Abstract: In a power source device including a battery pack, a safety switch is provided between a given pair of battery modules connected to each other. The safety switch connects and disconnects those battery modules by insertion and removal of a safety plug to/form a switch body. The power source device also includes an insertion prevention unit, such as a lock, for preventing the insertion of the safety plug to the switch body in such a manner that prevention of the insertion of the safety plug is releasable. A release operation unit is kept by a worker who removes the safety plug, so that safety of the worker against electric shock is ensured.

Abstract: In a ZIF connector having first and second connectors, the first connector includes an operating member rotatably held by a first insulator portion holding first contacts arranged adjacent to one another in a predetermined direction. The second connector includes a floating member held by a second insulator portion to be rotatable and slidable in the predetermined direction. The floating member has a first and a second surface which face the first contacts and the operating member, respectively, in a mutually fitted state of the first and the second connectors. Second contacts have one parts held by the first surface and arranged adjacent to one another in the predetermined direction. The floating member is rotated in a first rotating direction to bring the second contacts into contact with the first contacts when the operating member is rotated in the mutually fitted state.

Abstract: A terminal connection device is adapted for connecting two voice coils in a speaker between a series connection and a parallel connection wherein the terminal connection device includes a jumper housing and a terminal switch detachably mount thereto. The jumper housing includes a jumper circuit defining a plurality of jumper inlets adapted for electrically connecting with electric outputs of the voice coils respectively and a plurality of jumper terminals electrically extended from the jumper inlets respectively. The terminals switch includes a terminal circuit electrically connected with the jumper terminals of the jumper circuit for selectively switching the voice coils between a series connection and a parallel connection.

Abstract: A method for producing an ultraviolet light (UV) transmissive silicon nitride layer in a plasma enhanced chemical vapor deposition (PECVD) reactor is presented. The UV transmissive film is produced by reducing, in comparison to a standard silicon nitride process, a flow rate of the silane and ammonia gas precursors to the PECVD reactor, and significantly increasing a flow rate of nitrogen gas to the reactor. The process reduces the concentration of Si—H bonds in the silicon nitride film to provide UV transmissivity. Further, the amount of nitrogen in the film is greater than in a standard PECVD silicon nitride film, and as a percentage constitutes a greater part of the film than silicon. The film has excellent step coverage and a low number of pinhole defects. The film may be used as a passivation layer in a UV erasable memory integrated circuit.

Abstract: The invention concerns an analytical system in which at least two modules are in contact with one another by a connecting plug, and a connecting plug which is suitable for connecting modules. When two modules are connected by the connecting plug a part of the plug extends partially underneath the bottoms of the modules such that the plug connection is secured by the dead weight of the modules.

Abstract: An electric connection box 111 comprises a stationary unit 11 and a movable member 12. The stationary unit 11 is formed integrally with a box body 113. The movable member 12 is removably attached to the stationary unit 11. When the movable member 12 is detached from the stationary unit 11, the power supply from a battery to an electric load is interrupted.

Abstract: The present invention relates to a link bar for capacitors of an audio system, comprising a conducting portion and a connecting portion for connecting electrical poles of the capacitors together. The connecting portion stretches between the conducting portion. The link bar can be connected with another link bar by overlapping the connecting portions which will have the same height as the conducting portion after overlapping. In using the link bar, the desired number of capacitors are chosen and the link bars are assembled by mutually contacting the connecting portions. The maker can use one single link bar to connect capacitors instead of several kinds with various specifications of link bars.

Abstract: A switch-equipped connector device, comprises: a case having an opening; a cover to be removably mounted on the case so as to cover the opening; a first connection terminal on the side of load and a second connection terminal on the side of a power supply, a connection portion between which is exposed from the opening, and which are held in the case; a short-circuiting terminal attached to the cover; a switch connector located in said opening, the switch connector to be electrically connected to the short-circuiting terminal in the opening, the short-circuiting terminal being disconnected from said switch connector when the cover is removed from the case; and a switching device connected to the second connection terminal through the power supply, the switching device interrupting power supply to the second connection terminal when the cover is removed from the case.

Abstract: A removable automotive fuse block assembly for mounting to an automobile and disabling vital automotive electrical systems, comprising a fixed fuse block casement which is mounted to the automobile in a permanent fashion. A removable fuse block segment engages the fixed fuse block casement, both the fixed fuse block casement and removable fuse block segment having receptacles with electrical fuses contained therein which are in electrical communication with various automobile system circuits. The assembly is configured so that when the removable fuse block segment is disengaged from the fixed fuse block casement, vital automobile system circuitry is broken, and the automobile rendered inoperable. It is envisioned that an operator of the automobile, upon exiting, will disengage the removable fuse block segment and carry it with him, thus leaving the automobile in a non-functional state.

Abstract: A new vehicle anti-theft system for preventing theft of motor vehicles. The inventive device includes a module which is mounted within the vehicle's dashboard and which is connected to the vehicle's electrical power system and the vehicle's ignition system, and an audio unit which releasably connects with the module and which includes an electrical connection associated therewith which connects the electrical power system to the ignition system when the audio unit is connected to the module thus permitting the vehicle to be started. When the audio unit is disconnected from the module, the electrical power system and the ignition system are disconnected which prevents the vehicle from being started until the audio unit is again connected to the module.

Abstract: A fire detector includes both a detector unit and a detector base including a base block to which the detector unit is mounted. The detector unit has an outermost peripheral wall, an engaging portion located inwardly of the outermost peripheral wall, and connecting members of a bayonet coupling. The detector base includes coupling members of a bayonet coupling engaged with the coupling members of the detector unit. The bayonet coupling is locked in place by a locking spring of the base block of the detector base, which locking spring engages the engaging portion of the detector unit. A pair of spaced apart connecting terminals for connection with a power and signal line are fixed on the base block. These terminals have small holes, respectively.
