Patent JP-H0315295-A (JP)
Title: Double mode control type pulse width modulator
Inventor: DANIERU MAAKU SABURU
IPC: H02P7/29
Filed: 1990-01-26
Abstract: PURPOSE: To operate any load stably and efficiently by a combination of a hysteresis continuous mode controller making a transition between modes depending on the load and the state of a command and a variable frequency discontinuous mode controller. CONSTITUTION: A light load is operated in discontinuous motor current mode and a heavy load is operated in continuous motor current mode. A discontinuous current is a current decreasing to zero current within a finite time and continuous current is a current sustaining a level higher than zero. As the load increases, current pulses are generated more frequently until they are repeated continually. As the load increases furthermore, the hysteresis band begins to raise within a limit for transmitting a ramp signal of current and thereby a current pulse is superposed on a continuous current.

Title: Terminal metal fitting inspecting method and inspecting tool for multipolar connector
Inventor: TOMIKAWA KAZUYOSHI
IPC: H01R43/00
Filed: 1994-02-09
Abstract: PURPOSE:To inspect electric communication by installing a group of electric communication inspecting pins, which correspond to respective terminal storage chambers, in distinguishing additive parts formed at mutually different positions of a plurality of types of respective terminal metal fittings. CONSTITUTION:In a multipolar connector, female type terminal metal fittings C1 and C2 coated with gold and tin are stored in two terminal chambers in respective upper and lower steps. Distinguishing additive parts 2a, 2b projected toward the lower left and the lower right of the front of a female type electric contact part 2 are formed in these metal fittings C1 and C2. An inspecting tool D has four pairs of electric communication inspecting pins d1, d2 which correspond to the metal fittings C1, C2 and are put in an inspecting chamber 4 in the way they can slide freely in a supporting hole 5 and the tool D is pressed forward by a built-in spring. When a multipolar connector is inserted into the inspection chamber 4, the additive parts 2a, 2b of the metal fittings C1, C2 are brought into contact with the pins d1, d2 but not with the pins d2, d1. Consequently, electric communication and error insertion can be inspected simultaneously.

Title: Fuel cell power generating system
Inventor: SATOU YOSHIO
IPC: H01M8/06
Filed: 1982-02-01
Abstract: PURPOSE:To facilitate quick and stabilized follow-up sharp load change by installing a pressure device between a cell and a reformer in consideration of the difference of response of the cell and the reformer. CONSTITUTION:Carbon monoxide of a hydrogen rich gas 103 generated with a reformer 202 is removed with a shift convertor 203, then the hydrogen rich gas 103 is pressurized, and fed to a pressure tank 209. A fuel cell 205 opens or closes a cell inlet hydrogen adjusting valve 204 according to load variation to take in the required amount of hydrogen. Pressurized hydrogen in the pressure tank 209 can be used as auxiliary fuel when a load is increased or at starting by opening and closing an auxiliary valve 210. By this process, since the fuel cell 205 and the reformer 202 are controlled independently, quick and stabilized follow-up to sharp load change can be realized.

Title: Method for measuring field effect transistor
Inventor: SUZUKI KOUICHI
IPC: H01L21/66
Filed: 1981-02-05
Abstract: PURPOSE:To make it possible to measure parasitic resistance on a source side and ideal mutual conductance by measuring the mutual conductance of one of approximately identical, two field effect transistors and also that of two when they are connected in parallel. CONSTITUTION:The two FETs having an identical structure and approximately the same characteristics are prepared. A constant DC voltage is applied between a drain and a source and between a gate and a source of one FET so that a drain current becomes constant, and the mutual conductance thereof is measured. Then, the two FETs are connected in parallel, and the DC voltage which is applied between the gate and source is adjusted so that synthesized drain current become equal to the current set for one FET. Then the synthesized mutual conductance is measured. By using two measured values, the parasitic resistance Rs on the source side in the element and the ideal mutual conductance Gm without Rs are obtained. Thus, the measurement can be performed highly accurately under the actual operating state.

Abstract: PROBLEM TO BE SOLVED: To make it possible to transfer low-melting point metal through a simple process by rotating a transferring rotating body coated with molten solder under pressure and further pressing the rotating body against the tips of the metal bumps of a semiconductor chip to transfer the molten solder. SOLUTION: Molten solder 6 is prepared in a pot 5 in advance. A semiconductor chip 1 is pre-heated using a heater 7. Then a heat-resistant roller 8 is dipped in the molten solder 6 in the pot 5 to stick the solder to the roller, and is moved above the tips of gold bumps 2 on the chip 1. The roller is pressed against the tips 3 of the gold bumps 2 on the chip 1 coated with flux, and is rotated to transfer the molted solder 6. Thus a solder coat is obtained, and thereafter the flux is rinsed out. Since the height of the tips 3 of the gold bumps 2 is 5 microns or so, the sufficient solder coat is obtained, and connection with a printed board is facilitated.

Title: Annular data transmission system
Inventor: YAMAGUCHI HITOSHI
IPC: H04L1/00
Filed: 1980-02-13
Abstract: PURPOSE:To omit transmission for reception confirmation by considering reception to be done up to a reception order word when a data format has a reception confirmation frame. CONSTITUTION:Every time data is generated, a transmitting station transmits the data while increasing transmission order word NS. A receiving station returns transmission order word and reception order word NR with the transmission order word set to zero. Then, the transmitting station judges the data has arrived correctly by checking the value of reception order word NR, and then discards the data. When the receiving station has data to be sent to the transmitting station, transmission order word NS is increased and the data is transmitted. Thus, the same time slot can be used for both data transmission and reception confirmation.
