Magnetic disc storage unit for a computer

A booster lever unit includes a first lever pivotably supported by an object via a first pivotal shaft, a second lever pivotably supported by the object via a second pivotal shaft, and a linkage member that links the first lever to the second lever. The pivotal plane of the first lever is parallel to the pivotal plane of the second lever. The first lever has one end provided with an operation section, and another end provided with the first pivotal shaft, and the first lever further includes a first linker, the first linker being provided between the operation section and the first pivotal shaft and linked to the linkage member. The second lever has one end provided with an action section, and another end provided with a second linker linked to the linkage member, and the second pivotal shaft is provided between the action section and the second linker.

Booster lever unit

An enclosure of an electronic computing apparatus allows two electronic computing modules, each having a built-in fan, to be mounted in a perpendicular direction, when the two electronic computing modules are inserted, a shutter is at an intermediate position due to an elastic force of pushing a spring cover in a front surface direction, from push rods corresponding to the two electronic computing modules, and when one of the electronic computing modules is removed, the elastic force of pushing the cover from the push rod on the removal is lost, and the shutter moves, around a rotating mechanism, to a side of a housing space on the removal side and shuts off a flow path in the housing space.

Portion of a magnetic disc storage unit for electronic computer

A toner for developing an electrostatic charge image, the toner including: elemental iron, wherein a content of the elemental iron is in a range of 1.0&#xd7;10to 1.0&#xd7;10ppm, based on a total weight of the toner; elemental silicon, wherein a content of the elemental silicon is in a range of 1.0&#xd7;10to 5.0&#xd7;10ppm, based on a total weight of the toner; elemental sulfur, wherein a content of the elemental sulfur is in a range of 500 to 3,000 ppm, based on a total weight of the toner; optionally elemental fluorine, wherein a content of the elemental fluorine, if present, is in a range of 1.0&#xd7;10to 1.0&#xd7;10ppm; and a binder resin.

Toner for developing electrostatic charge image and method for preparing the same

A toner for developing an electrostatic charge image includes three or more elements selected from a group including an iron element, a silicon element, a sulfur element and a fluorine element and a binder resin including an amorphous polyester-based resin.

Magnetic disk storage unit for electronic computer

Storage apparatus configured to provide an external apparatus with logical storage area as data storage area, the storage apparatus having a physical storage medium configured to generate the logical storage area, and storage controller communicatively coupled to physical storage medium to control data input/output processing between the external apparatus and the logical storage area, wherein the storage controller includes circuit package including circuit board which implements predetermined function of storage controller and a circuit board case to accommodate the circuit board, plurality of cooling fan units that generate cooling air for cooling circuit component mounted on the circuit board of the circuit package, and a chassis having a structure for accommodating the circuit package and the cooling fan units, some of circuit packages are inserted to be accommodated in chassis from opening thereof and are arranged side by side across width direction of chassis.

Storage apparatus and storage controller of storage apparatus

A control unit is proposed which makes it possible to prevent connection problems between a package box and a backboard and prevent damage to the connector of the backboard. The control unit comprises a unit cover in which a first package box, which comprises a predetermined function and on the rear side of which a first connector is provided, is inserted into the corresponding spatial area so as to move over a shelf from an open end [of the unit cover]; and a backboard which is disposed inside the unit cover and on which a second connector is provided in a position where the first package box, inserted in the corresponding spatial area, mates with the first connector, wherein the shelf is provided with a protrusion which rotatably supports the first package box in a fan direction.

Controller

In a storage device accommodating a plurality of memory devices in a general-purpose chassis provided from both of the surface sides thereof, a cooling device is provided on the front of the memory devices. This cooling device is allowed to freely move to leave available the area in front of the memory devices, thereby enabling maintenance and replacement of the memory devices from the both surface sides of the chassis. With such a storage device of a type using a general-purpose chassis, and inserting therein a plurality of memory devices from the both surface sides thereof, even if a cooling device is located on the front of the chassis, the memory devices can be subjected to maintenance and replacement.
