Title: Printed wiring board
Inventor: SAEGUSA HIROSHI
IPC: H05K3/00
Filed: 1993-08-16
Abstract: PURPOSE:To effectively avoid a solder bridge between a solder land part and a through hole by a method wherein printing with a specific width is performed with an ink on a board surface surrounding a land part or a circuit pattern. CONSTITUTION:A surface of a through hole 3a containing a circuit pattern 2 that is not used as a solder land and both surfaces of a board 1 that the circuit pattern 2 is not formed are coated with an insulating solder resist ink 7. Therefore, a silk ink 6 is printed and simultaneously part number letters of a land part 5 are printed thereon. The surface of the through hole 3a that is not used as a solder land is coated and also a hole part 30a is blocked up with a solder resist ink 7 and the silk ink 6 is printed therefrom. Accordingly, the through hole 3a is insulation-sealed and a bridge between a solder land part 4 and the through hole 3a in the vicinity thereof can be more positively avoided than when only a conventional resist ink 7 is used.

Abstract: PURPOSE:To improve the efficiency of operation by fixing an eccentric body to a home position by means of fixtures to make stroke exactly changeable in the stage of rotating a revolving shaft and changing the stroke. CONSTITUTION:The tooth profiles 18b of fixtures 19 are pressed to the tooth profiles 18a of an eccentric body 4 via a support fitting 22 by means of a hydraulic cylinder 25 incorporated with a relief valve in the circuit. The body 4 is fixed and held by the fixtures 19. A hydraulic chamber 13 is then pressurized and the meshing parts 9, 10 of a boss 5 for fixing the rate of eccentricity are removed. A revolving shaft 1 is rotated and is stopped when a desired stroke length is attained.

Title: Control system for fuel cell air supply system
Inventor: NAKAYAMA TAKASHI
IPC: H01M8/04
Filed: 1987-08-17
Abstract: PURPOSE:To simplify a control structure as well as to make a stable supply air flow rate controllable by installing a cathode supply air flow controlling three-way valve which distributes air fed out of a compressor of a turbocompressor to a pipeline to to cell cathode side and a pipeline to a mixing chamber or the turbine inlet side. CONSTITUTION:As control over an air flow rate between the cell cathode side and the system differential pressure side, there is provided with a three-way valve which distributes air fed out of a compressor of a turbocompressor 2 to a pipeline 4 leading to the cell cathode side and a pipeline 7 leading to a mixing chamber or the turbine inlet side in place of using each one valve. With this constitution, when a cathode supply air low rate becomes lessened, a bypass air flow rate to the mixing chamber or a turbine inlet is automatically increased, and since both air flow rates come to supplementary relations with each other, the flow rate as a whole is not changed, but a pressure variation at the valve upstream side lessens, whereby stable air flow control can be done in the same manner as in case of control with two pieces of a two-way valve, and that a control structure is simplified and, what is more, system efficiency is also improvable.

Title: Memory access controller
Inventor: SAKAI MASANAO
IPC: G06F11/20
Filed: 1993-08-17
Abstract: PURPOSE:To shorten the waiting time of a microprocessor by performing the connection control of a data transfer route each time the request of access to a shared memory is generated, and arbitrating competing access requests at an access arbitration part when the access requests compete. CONSTITUTION:This controller is provided with access arbitration parts 10a and 10b for performing the arbitration of access requests and the instruction of a route to be connected to access control parts 5a and 5b for performing the connection control of the data transfer route by decoding an address signal containing a device address and a memory address. Each time the request of access is generated, the access route from microprocessors 2a and 2b to shared memories 3a and 3b is secured by the access arbitration parts 10a and 10b. Therefore, the microprocessors 2a and 2b can access the shared memories 3a and 3b without processing the occupation request of the shared memories 3a and 3b. Further, the waiting time can be reduced by arbitrating the access requests at the access arbitration parts 10a and 10b when the shared memories receive the access requests.

Title: Composite transistor
Inventor: FUJIWARA HIROKI
IPC: H01L29/73
Filed: 1982-11-22
Abstract: PURPOSE:To obtain a high speed switching device of low power drive by respectively inserting the drain and the source of an FET between the collector and the base, and between the base and the emitter of a bipolar element. CONSTITUTION:When a positive control voltage is applied to a gate G, an NchFET4 between the base and the collector of an element 2 is conducted to conduct the element 2. In this case, since the element 2 is shortcircuited only between the B and the C, VCE does not lower as compared with a saturated voltage, storage carrier produced in the base of the element 2 is less, its adverse influence is reduced so that the FET4 of small capacity is sufficient. When zero or negative control voltage is applied to the gate G, the FET4 is turned OFF, the PchFET5 between the B and E of the element 2 is conducted, the storage carrier in the base of the element 2 is discharged, and the FET5 may be small capacity. According to this structure, a drive circuit which has extremely less power consumption with simple structure can be obtained in combination with a bipolar transistor and the FET, and the element having small size and high efficiency can be obtained.
