Patent JP-H0722050-A (JP)
Title: Fuel cell power plant
Inventor: FUNATSU TETSUYA
IPC: H01M8/04
Filed: 1993-07-05
Abstract: PURPOSE:To stabilize the pressure and temperature that a steam system requires by increasing or decreasing the opening of cell cooling water control valve using a predetermined function according to the temperature detected by a temperature detector or a set temperature value. CONSTITUTION:Cell cooling water is supplied from a cooling water source to the inlet of the cell cooling pipe of a fuel cell main body 1 and to a steam separator 13. Water separated from the separator 13 is returned to the cooling water source 18 through a circulation line, and a steam system 17 receives steam generated by the separator 13. A control valve 12 is disposed at the outlet of the cell cooling pipe 2 to increase or decrease the cell cooling water according to a temperature value detected by a temperature detector 20. The detector 20 detects the temperature within the fuel cell or a set temperature value, and a controller 21 increases or decreases the aperture of the control valve 12 according to the detected value using a predetermined function. Then the steam generated by the separator 13 can be supplied to the system 17 with its pressure and temperature stabilized, and the pressure and temperature that the system 17 requires can be stably reached.

Title: Mos-type semicondutor device
Inventor: TANAKA TAKESHI
IPC: H01L29/78
Filed: 1981-10-16
Abstract: PURPOSE:To increase drain withstand voltage and to prevent reduction in length of a drain by a method wherein an n type source, drain, and channel, of the same impurity concentration, are built in a p type Si substrate. CONSTITUTION:Ions are implanted in a p type Si layer 101 through a gate oxide film 103 with a field oxide film 102 serving as a mask, which process results in the provision of an n<-> type source 104, drain 105, and channel 106, of the same impurity concentration. Then a MOSi2 gate electrode 107 is built by sputtering and photo etching. A CVD SiO2 layer 108 is formed, wherein openings 1901, 1092 are provided and Al wirings 110, 111 are attached thereto. Lack of a convertional n<+> type drain eliminates the concentration of an electric field along the boundary between drain and channel, thereby markedly heightening the drain withstand voltage. Further, the drain/source being substantially, extremely shallow, the channel is checked from being reduced in length and enhanced integration is ensured. The gate electrode may be built of a silicide of one of other high melt point metals or of doped poly Si. The substrate may be of n type Si or an Si layer on an insulator-made substrate.

Filed: 1991-06-10
Abstract: PURPOSE:To prevent the occurrence of combustion trouble by providing a pressure sensor on both of, or on one of, the primary side and secondary side of a pressure regulating mechanism for a gas feed system to a burner, and controlling a gas control unit according to programs and data stored in advance. CONSTITUTION:By providing pressure sensors 2, 2' on the primary side and secondary side of a gas rate control unit 20, the feedback of secondary pressure to the gas rate control unit 20 becomes possible, and the necessary control of a secondary pressure correction is effected. As concrete operation, when a pressure value of the pressure sensor 2' on the secondary side of a governor falls outside a predetermined range by fluctuation in a gas feed pressure or by deterioration in the pressure control unit 20, a central processing unit 21, which has received this input, performs the control of a correction corresponding to a portion which falls outside the predetermined range with respect to the gas rate control unit 20. Thereby, safety of combustion performance of a burner can be enhanced.

Abstract: PROBLEM TO BE SOLVED: To evenly keep the inner temperature of a fuel cell at a temperature close to the optimum temperature. SOLUTION: In a fuel cell apparatus 20, cooling water circulating in a cooling water route 28 is heated by heat-exchange in a fuel cell 22, then cooled in a radiator 26, and again supplied to a fuel cell 22.

Title: Packet switching network route selection system
Inventor: OYOSHI SHOJI
IPC: H04L45/247
Filed: 1989-06-28
Abstract: PURPOSE:To send a packet by providing a detection means for disabled connection remoter from an adjacent network and a priority route block means so as to allow a call packet switching network to be bypassed even when a route remoter from an adjacent packet switching network has a fault. CONSTITUTION:When a caller packet switching network 1a receives a restoration request packet from a packet switching network 1b, a detection means 3 for disabled connection remoter from an adjacent network decides that a route 2c ahead an adjacent packet switching network 1b is disabled of connection, the means 3 informs disabled connection of the route 2c to a priority route blocking means 4. The priority route blocking means 4 blocks a route 2a with the highest priority to the connection to the packet switching network 1d and selects the route 2b with the 2nd priority to the succeeding packet transmission to the packet switching network 1d. Thus, even when the route disabled of connection farther than the adjacent packet switching network exists, the call packet switching network is bypassed and the disabled transmission of the packet is not caused.

Abstract: PURPOSE: To secure repeated feed of the same paper sheet in the case of the paper feeder of a both-sides copier without any pinch roller, by means of a multi-feed preventing retard roller and a paper leading edge entry guide plate installed near the feed roller.  
     CONSTITUTION: A paper sheet 13 with its one side already printed stays in its standby position alter its leading edge is inserted between a feed roller 3 and an entry guide plate 10 by means of the transporting pressure and dropping inertia of the weight, and those copied paper sheets are thus piled there successivly. Next, when the roller 3 is driven, transportation of paper sheet 13 1  is started. Then, the paper sheet just above said paper sheet 13 1  is transported simultaneousy but it is blocked after being separated from the lower paper sheet 13 1  owing to the reverse rotation of a retard roller 4. The paper sheet 13 1  is after reaching transport rollers 12, accelerated by high rotational speed of rollers 12 through allowable racing of a one-way clutch 3c. Here, when the trailing edge of the paper sheet 13 1  leaves the roller 3, the speed is recovered to its origianl level to be ready for starting transportation of the next paper sheet.
