Abstract: The present invention is directed to a network attached data storage system. In one embodiment of the invention, the system provides high data density by providing the capability to mount four data storage devices, such as disk drives, in a row that extends across the width of an enclosure that conforms to the 1U specification. In a further embodiment, the system includes a latch that allows a data storage device that is disposed on a carriage to be attached and detached from a receiving bay within a disclosure. The latch includes a sensor that provides an electrical signal which is indicative of when a user is disengaging the latch to remove the data storage device from the enclosure. This signal can be used to prevent any data that is being transferred to or from the data storage device from being lost and/or corrupted during removal of the data storage device.

Abstract: A computer casing includes a cage (10), a fastener (109), and first and second side panels (20, 30). The cage includes a top panel (100). The fastener is mounted to a bottom surface of the top panel, and includes a body (112), an elastically deformable resilient plate (114), a slider (116), and a spring (118).

A conductor fills the through hole (16), thereby suppressing skews resulting from a difference in interconnect line length on the circuit module and decreasing a stub capacitance to achieve the reduction in power consumption.

Abstract: In an assembling structure of a vehicle center cluster, plural electrical devices are detachably assembled to a holding member to be removed from an inside of a passenger compartment while the holding member is fixed to a dashboard. Therefore, for example, when a CD deck is removed from the center cluster into the passenger compartment among the electrical devices, only the CD deck can be removed from the holding member into the passenger compartment without removing the other electrical devices, in a fixed state of the holding member to the dashboard. Accordingly, removing operation of the electrical devices can be made simple.

Abstract: An acceleration sensor is disclosed which includes a capacitance-type acceleration detection element mounted on a ceramic base plate. The element comprises a movable electrode mounted between a pair of fixed electrodes. Acceleration of the sensor in a measurement direction causes the movable electrode to move relative to the fixed electrodes and the element has opposite ends in a direction perpendicular to the measurement direction. The acceleration detection element is mounted on the base at a first one of the opposite ends. Accordingly, the mounting surface of the acceleration sensor is parallel to the direction of acceleration to be detected. Thus the acceleration sensor can be surface-mounted on a printed board, and more be easily mounted in an automobile air bag control system or the like.

Abstract: An automatically operating interlock prevents connection of an electrical device within a cabinet unless the cabinet door is closed. The interlock is particularly useful for circuit breakers contained within arc-resistant cabinets. The interlock includes a spring-biased locking plate reciprocating between a locked position wherein the locking plate resists movement of the levering-in locking plate, and an unlocked position wherein the locking plate permits movement of the levering-in locking plate. The locking plate is spring-biased towards its locked position, and is pushed from its locked position to its unlocked position when the cabinet door is closed. Access to the hex drive of the levering-in rod is thereby resisted when the cabinet door is open.
