Abstract: PURPOSE:To reduce the thermal loss of a fuel cell by connecting two adjacent electrodes at a short distance by dividing the said electrodes into small areas, and inserting  a plural number of conductive elastic members, which are fixed to a battery frame, between the divided small areas so as to connect the surfaces of the said electrodes. CONSTITUTION:Unit cells, each of which has an oxidant electrode 5', a fuel electrode 4' and an electrolyte chamber 6, are stacked by interposing battery frames 14, the surfaces of each of which are provided with an oxidant chamber 10 and a fuel chamber 9, between them. At the same time, an oxidant electrode 5' and a fuel electrode 4' adjacent to one another are electrically connected so as to take electricity outside the fel cell. Here, the electrodes 4' and 5' are divided into small areas, insulating frames 12 are provided on the electrolyte chamber 6 sides of the divided surfaces, and current collecting bodies 11 are provided on the opposite sides of the divided surfaces. Then, the electrodes 4' and 5' are connected by making plural conductive elastic members 12, which are fixed to the frame 14, in close contact with the current collecting bodies 11. Consequently, the generation efficiency of the fuel cell can be enhanced by re ducing the thermal loss caused by the electric resistance of the electrodes 4' and 5' by connecting them at a short distance.

Title: Semiconductor device
Inventor: MATSUBA SHIYOUICHI
IPC: H01L29/73
Filed: 1992-04-13
Abstract: PURPOSE:To prevent a drop in a current amplification factor by forming a low concentration base region on an internal base. CONSTITUTION:An necessary portion of an epitaxial layer 2 formed on a silicon board 1 excluding an internal base region 7 is etched and thereby removed so as to form a low concentration base region 16. The presence of this low concentration base region 16 forces the photocarriers to be generated at a depth far separated from the surface of the board 1 when a reverse bias is applied to a base junction in a reverse direction. Therefore, the photocarriers are subjected to the relaxation inducted by their scattering until they reach the surface of the board 1 and lose their energy and injected into an oxide film 9 on the board 1 while they are prevented from disturbing the interface between a polycrystalline silicon film 10 and the silicon oxide film 9. This construction makes it possible to prevent a drop in a current amplification factor during the operation of a bipolar transistor.

Title: Switching device of drive power for four wheel drive car
Inventor: TAKAHASHI JIYUNICHI
IPC: B60K23/08
Filed: 1980-09-01
Abstract: PURPOSE: To facilitate switching between runnings of 4-WD and FF by adapting planet gears to a drive-switching part to keep a gear mechanism constantly engaged for braking a ring gaer or the like of 4-WD running and releasing the braking for FF running.  
     CONSTITUTION: When a brake band 24 of a drive power switching device is in a released state, the power given to a shaft 18 is transmitted to a ring gear 20a via a planet gear 21a rotatable round a shaft 23, and the said gear 20a is rotated in the same wise with the shaft 18. At this stage, a ring gear 20b is fast fixed, and planet gears 21a and 21b are shifted in the same direction via the shaft 23. Consequently, shafts 18 and 19 are optionally rotatable, and rear wheels 7 are free from the power for obtaining FF running. Meanwhile, when the brake band 24 is pushed to the gear 20a, the gear 20a is stopped, and the shaft 19 is rotated in the same wise with the shaft 18 for obtaining 4-WD running.

Abstract: PURPOSE:To improve line utilization efficiency by reading a picture data stored by a picture data storage means from a head and tail respectively at transmission, assigning the picture data to different communication channels and sending the result thereby decreasing the time when only one communication channel is idle. CONSTITUTION:In addition to a picture data storage means 100 storing the picture data of the transmission original, a picture data read control means 200 and a transmission control means 300 are provided.
