A hard disk drive (HDD) includes an enclosure base, a first cover coupled to the base, and two separate gasket seals composed of different materials and configured to seal the interface between the first cover and the base. One gasket seal is composed of a material having a low permeability to helium or another lighter-than-air gas contained within the HDD, and the other gasket seal is composed of material having a low water vapor or moisture transmission. By using two separate independent gaskets which have different attributes, the lighter-than-air gas concentration is kept high and humidity is kept low during manufacturing testing, prior to affixing a hermetic second cover over the first cover, and degradation of HDD performance due to change of flying height is ultimately avoided.

Dual gasket for manufacturing of hermetically-sealed hard disk drive

Described herein is a multilayer flex circuit having a first dual flex circuit and a second dual flex circuit where each one comprises an outer metal layer, a base insulation layer, and an inner metal layer. The base insulation layer is disposed between the outer metal layer and the inner metal layer. The inner metal layer of the first dual flex circuit is configured to face toward the inner metal layer of the second dual flex circuit. The multilayer flex circuit also includes a coupling layer that adhesively couples the inner metal layer of the first dual flex circuit to the inner metal layer of the second dual flex circuit. The multilayer flex circuit also comprises an electrically conductive material that electrically connects the inner metal layer of the second dual flex circuit to the inner metal layer of the first dual flex circuit.

A hard disk drive (HDD) includes an enclosure base, a first cover coupled to the base, and two separate gasket seals composed of different materials and configured to seal the interface between the first cover and the base. One gasket seal is composed of a material having a low permeability to helium or another lighter-than-air gas contained within the HDD, and the other gasket seal is composed of material having a low water vapor or moisture transmission.

An electrical feed-through involves a laminate structure having alternating insulator and metal layers with electrically conductive through-holes formed therethrough, by which a lower connector pad is electrically connected with a corresponding upper connector pad, and wherein the number of through-holes is less than the number of connector pads on either side. Thus, the chain of clearances associated with the through-holes on the inner metal layer(s) is reduced, which provides more leak resistant metal material within the metal layer(s), while maintaining suitable electrical performance and avoiding disruption of existing manufacturing. Such a feed-through may be used at an interface between a hermetically-sealed internal environment, such as in a lighter-than-air gas filled data storage device, and the external environment.

Sealed electrical feed-through having reduced leak rate

A flexible type electrical feed-through involves a flexible printed circuit (FPC) part constructed as a laminate structure of a base insulating layer, a conductor layer, and a cover insulating layer, where the FPC part is wrapped around a metal part, forming a connector assembly. Such a feed-through may be used at an interface between a hermetically-sealed internal environment, such as in a lighter-than-air gas filled data storage device, and the external environment. Multiple connector parts may be coupled to an inner side of the feed-through, to each mate with a respective flexible cable assembly electrically connected to a respective actuator of a multi-actuator hard disk drive. A floating board-to-board connector part may be coupled to the outer side of the feed-through, which in turn is electrically connected to a printed circuit board assembly of a hard disk drive, and which is able to tolerate connector mating misalignment.

Flexible type electrical feed-through connector assembly

Described herein is an apparatus that includes a housing that defines an interior cavity. The housing also includes a feedthrough aperture. The apparatus also includes an electrical connector that is coupled to the housing over the feedthrough aperture. The electrical connector includes a base, a plurality of pins extending through the base, and a skirt positioned about a periphery of the base. The pins extend from a location external to the housing to a location within the interior cavity of the housing. Further, an inner surface of the base is co-planar with an outer end of the feedthrough aperture. The apparatus also includes solder positioned on the housing and against an entire periphery of the skirt to seal the electrical connector to the housing.

An image forming apparatus includes a renderer configured to render a one page amount of image data based on intermediate data generated by either a first execution unit or a second execution unit, a printer engine configured to form image data of a page rendered by the renderer on a recording medium, and after forming the image data, stop each unit in the engine when there is no image data formation instruction corresponding to a next page of the page even after a cycle down time limit has elapsed, and a request unit configured to, during generation of intermediate data of a predetermined page by the first execution unit, request an extension of the cycle down time limit set in the printer engine based on a number of pages of rendered image data corresponding to intermediate data of pages following the predetermined page.

Image forming apparatus, control method thereof, and storage medium

An image forming apparatus to generate image data of print data containing a drawing object for reuse within a job includes a cache unit, an object parallel processing unit, a page parallel processing unit, and a processing control unit. The cache unit generates data based on the drawing object and caches generated data. The object parallel processing unit divides each page of the print data per drawing object unit and subjects a divided page to raster image processor (RIP) processing in parallel. The page parallel processing unit subjects the print data to the RIP processing per page unit. The processing control unit controls such that, in the print data, the object parallel processing unit executes processing sequentially from an initial page until the data having a value equal to or more than a threshold value is cached and the page parallel processing unit executes processing after the data is cached.

Image forming apparatus, method for controlling image forming apparatus, and storage medium

An image forming apparatus includes first and second interpreters configured to interpret page description language data and generate intermediate data. The apparatus further includes a setting unit configured to set an image quality priority mode for one of the first and second interpreters and a color/monochrome determination priority mode for the other of the first and second interpreters. Either the first interpreter or the second interpreter, for which the color/monochrome determination priority mode is set, skips the generation of the intermediate data for a processing target page in a case where it is determined that the processing target page is a color page.

Image forming apparatus, information processing method, and storage medium

A Web server function is provided for an image processing apparatus including a scanner for reading an image on a document, a printer for printing an image, an E-mail transmission/reception function, a FAX transmission/reception function, and the like to make the image processing apparatus generate a list of information about the status of various jobs and image data stored in a storage unit as a Web page. A user can browse and operate this Web page by using the Web browser of a computer connected to the apparatus through a LAN. The user of the computer can therefore grasp and manipulate information about a plurality of jobs executed by the image processing apparatus and information about image data at a remote place from the image processing apparatus.

It is determined whether the rasterization result of a rendering object is cashed. If it is determined that the rasterization result of the rendering object is not cashed, an image and a mask for the image are generated from the rendering object. The generated image and the generated mask are stored in a cache. If it is determined that the rasterization result of the rendering object is cached, an image and a mask are extracted from the cache. The extracted image is rendered on a portion of the extracted mask so that a background image remains on a portion other than the portion of the extracted mask.

Rendering apparatus, rendering method, and computer-readable storage medium

A color display apparatus is of the type wherein a unit pixel is constituted by at least three subpixels including first to third subpixels, and at each subpixel, a medium for changing an optical property depending on a voltage applied thereto is disposed. The color display apparatus includes means for applying a voltage, to each of the first to third subpixels, for changing the optical property of the medium within a brightness change range in which light passing through the medium is changed in brightness and a hue change range in which the light passing through the medium assumes chromatic color and a hue of the chromatic color is changed while including combinations of red and green, red and blue, and green and blue for the first to third subpixels, respectively.

Color display apparatus

This invention can substantially equally distribute a load necessary for rendering, and can complete printing all pages of one print job at high speed. A master printer interprets received print data, generates display list data as intermediate data for each page, and upon completion of generating intermediate data of all pages, transfers them to a slave printer. The master printer performs rendering (RIP) in an ascending page order of page numbers 1, 2, . . . , whereas the slave printer performs rendering in a descending page order from the final page. When the number of rendered pages held by the master printer does not reach half of all pages upon completion of rendering all pages, the master printer receives the rendering results of deficient pages from the slave printer. Then, each printer prints by almost the same number of pages.

Printer system for generating intermediate data in distributed printing

A voice coil includes a stack of a plurality of layers of aligned windings held between an outer holding portion and an inner holding portion of the carriage assembly. The carriage assembly is formed integrally with the voice coil through injection molding. An outermost peripheral layer is a conductive wire wound a number of turns that falls short of the number of turns required to constitute a complete layer. A step is thereby formed between the outermost peripheral layer and a layer adjacent thereto and inner therefrom. The outer holding portion includes a reinforcement portion formed thereon to cover part of a transverse end face of the voice coil. The outermost peripheral layer opposes a force acting on the outer holding portion from top downward and the reinforcement portion opposes a force acting on the outer holding portion from bottom upward.
