IPC: H01M8/04
Filed: 1993-02-16
Abstract: PURPOSE:To prevent a fuel cell from being damaged by detecting a gas shortage condition which locally takes place in a cell stack when a command is directed to increase fuel cell loading, and thereby suspending the operation of the fuel cell for protecting the cell. CONSTITUTION:A fuel cell stack 1 is divided into a plurality of cell blocks 1a, 1b, 1c,...1f and the like while plural unit cells are made to be one unit, so that each voltage Va, Vb, Vc,...Vf and the like in each cell block is thereby detected by a voltage detector 22. Detected voltage is compared by a judging means, with a protection level set value Vp determined in advance when either one of respective voltages Va, Vb, Vc,...Vf and the like for the cell blocks is found to have been lowered to the protection level set value Vp in a process that the output electric power of fuel cell stack is quickly increased by a load change command 9s, it is judged that gas shortage takes place in some cell blocks, so that the fuel cell is suspended in operation so as to be protected.

Title: Bipolar transistor
Inventor: TSUBATA TAKESHI
IPC: H01L29/72
Filed: 1981-02-27
Abstract: PURPOSE:To contrive high power output for the bipolar transistor by a method wherein the distribution of the windows, to be used to lead out the emitter electrode provided on an insulating film, is coarsely formed within the row on the inner side of the emitter region and the windows are densely formed within the row on the outer side of the emitter region. CONSTITUTION:The distribution of windows 1', provided on the second insulating film 12 on a polycrystalline Si layer 3, are changed between the inner side and the outer side of the emitter region arrangement. The interval within the row of the square windows, having a side of several mum, is narrowered outside the emitter region arrangement. The stabilized resistance per row of the emitter region is reduced in proportion to the narrowering of the interval within the row. According to this constitution, as the emitter stabilized resistance becomes larger as it approaches to the center region of the junction, the temperature distribution is equalized, thereby enabling to drop the operational temperature of  the bipolar transistor. As a result, high output characteristics can also be improved.

Abstract: PURPOSE:To eliminate a delay of control so as to improve a purifying effect of exhaust gas in the case of an engine stably loaded by previously adjusting air-fuel ratio of a mixture, supplied to a combustion chamber, with an immediately preceding data and differentiating time just before lean and rich changes of the air-fuel ratio. CONSTITUTION:Air-fuel ratio in the next time is previously adjusted on the basis of an immediately preceding air-fuel ratio based on an output signal of an O2 sensor 12, and the adjusted result if further utilized for the next time, as a result a deflecting width of the air-fuel ratio is decreased by eliminating a delay of control. When a time for changing fuel from its decrease side to increase side is delayed by shortening set time just before changing the air-fuel ratio from its rich to lean on a low load side, an increase amount of fuel is decreased, so that the control center of the air-fuel ratio is changed to a lean side. On the other hand, when a time for changing the fuel from its increase side to decrease side is delayed by shortening set time just before changing the air-fuel ratio from its lean to rich on a high load side, the increase amount of the fuel is increased, so that the control center of the air-fuel ratio is changed to a rich side.

Abstract: PROBLEM TO BE SOLVED: To reduce an adverse effect when a photographing action is executed while a window is covered with a finger by arranging the plural windows in a line according to the seriousness of the adverse effect exerted on the photographing action when the window is covered with the finger so that the window exerting the more serious adverse effect is positioned, nearer to the more center of a camera. SOLUTION: The remote control light receiving window 10, the red eye phenomenon reducing light emitting window 9 and the photometry window for automatic exposure 8 are fitted in turn from the side surface of a camera body 1 at the lower part of the stroboscopic light emitting window 7. Besides, the finder objective window 6, the AF light receiving window 5 and the AF light projecting window 4 are arranged near to the center of the body 1. When the photographing action is executed while the window 8 is covered with the finger, an automatic exposure device does not normally function. Since the normal photographing action also cannot be executed when the window 4, the window 5 or the window 6 is covered with the finger, the window 8 is prevented from being covered with the finger in comparison with the windows 9 and 10.
