A frame search processing apparatus includes a frame information extraction unit () that extracts frame information from an input frame, a search processing unit () that compares the frame information with entry information, and a frame information output control unit () that controls output of the frame information to the search processing unit (). The search processing unit () includes a plurality of comparison units that read out N pieces of entry information from a search table, and perform comparison between the entry information and the frame information at once. The frame information output control unit () includes a frame information buffer that accumulates the frame information, and an output processing unit that, when triggered by a predetermined accumulation count of the frame information or an elapse of a predetermined accumulation time of the frame information, distributes a plurality of pieces of frame information accumulated in the frame information buffer to the comparison units of the search processing unit () one by one.

Frame search processing apparatus and method

The end of a communication period can be detected reliably and efficiently by a control unit and validity/invalidity of search rules in a search table can be effectively managed. A timer is provided so as to correspond to each entry area of the search table. Then, under control of a timer managing unit, the timer starts a counting operation whenever information is written in a validity management table or a packet in which a communication parameter matches a packet search condition corresponding to information on the validity management table that is set as valid is received. In addition, when a counting time of the timer exceeds a preset time-out time, information indicating the time-out is stored in a time-out management table.

Packet transfer processing device, packet transfer processing method, and packet transfer processing program

A plurality of heads with a plurality types of ink each having a different density for the same color filled therein and ejecting the ink are provided, and also a control means for controlling volume of ink drops ejected for each dot is provided. When forming a pixel, a head is selected by the control means with volume of ink drops ejected from each head controlled, and two or more types of ink are ejected at one position with varied dot diameter for representation of density gradations.

Ink jet printer

A multiple element printer including a printhead arranged with N of printing elements for printing dots on a surface of a receiving medium at intervals of k dots where k and N are positive integers mutually prime with each other, in a direction of feeding the receiving medium, first driving device for driving the receiving medium in the direction of feeding the receiving medium, second driving device for scanning the printhead in a direction of print lines orthogonal to the direction of feeding the receiving medium, data forming device for outputting previously stored information data for printing the information data onto a surface of the receiving medium, printing element drive signal forming device for outputting to the printhead printing element drive signals for driving the respective printing elements based on the information data such that a 1.sup.st one of the printing elements and an Nth one of the printing elements alternately printing the dots at odd ordinal numbers and the dots at even ordinal numbers on substantially the same print lines and controlling device for controlling the first driving device such that the receiving medium is moved by a distance of P dots where N=P+1 at every printing and scanning of the printhead in the direction of the print lines.

Multiple element printer and method of adjusting thereof

An image filing method, in which a plurality of images are registered one by one, and the registered images are retrieved by adding a retrieval condition so as to be simple and not require time and labor at the registration and retrieval times. A plurality of symbols for featuring objects in the images are set in advance, and the images are registered corresponding to the selected symbols. At the image retrieval time, the symbols are selected, and the images corresponding to the selected symbols are read out.

Image filing method based on symbol retrieval condition

A color image reading apparatus includes a multi-chip image sensor having a plurality of image sensor units adapted to read a test chart comprising a color slip having a plurality of colors. A processing circuit is provided for automatically calculating color correcting coefficients, respectively, for the plurality of image sensors and storing them in memory. This will reduce problems of color reproducibility among image sensors and among image reading apparatus.

Color image reading apparatus including color correction means

An electric motor assembly for driving an air blower is disclosed. The assembly comprises a casing of metal, the casing having opposed open ends closed by respective covers of metal; a rotation shaft rotatably disposed in the casing, the rotation shaft having one end exposed to the outside through an opening formed in one of the covers, the one end being adapted to connect to a fan of the air blower; a plurality of magnets installed in the casing and circumferentially surrounding the rotation axis; an armature mounted to the rotation shaft to rotate therewith; a commutator mounted to the rotation shaft and electrically connected with the armature; brushes operatively contacting with the commutator and supported by the casing; and an electric power feeding device for feeding the brushes with an electric power. A pulse width modulating device is further employed which is electrically connected with the power feeding device for modulating the electric power by means of a pulse width modulation method. The pulse width modulating device is installed in the casing for radio noise suppression.
