Title: Solar cell, solar cell module, installation of the solar cell module and manufacture thereof
Inventor: YAMANO MASARU
IPC: H01L31/04
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To reduce the extraction loss of carriers to obtain a solar cell having superior characteristics by a method, wherein a take-out of a minority carrier out of the light producing carriers, which are produced in a crystal system semiconductor layer, is conducted from both sides of the semiconductor layer. SOLUTION: Extraction of electrons, which are a minority carrier, is conducted from both sides of a crystal system semiconductor layer 1 through first and second electrodes 3 and 5. Owing to this, the electrons produced at the regions close to the electrodes 3 and 5 in the interior of the layer 1 are respectively taken out through the electrodes 3 and 5. Moreover, both of the electrodes 5 and third electodes 6 are provided in such a way as to distribute almost evenly on the whole surface on the side of the light-transmitting surface of the layer 1. Power extraction through the electrodes 5 and 6 is conducted via electrode extraction regions 5A and 6A provided at the end parts, which face opposite to each other, of the layer 1.  As a result, the distance to be diffused by minority carriers can be shortened, and the effective utilization of light producing carriers, which are produced in the layer 1, is realized.

Title: Memory circuit
Inventor: KUSUMOTO ETSUO
IPC: G06F7/24
Filed: 1983-02-14
Abstract: PURPOSE:To attain sorting only by one writing cycle by connecting a sorting memory to a data bus in parallel and comparing the size of data from the data bus, data held in a self-memory and the prestage data. CONSTITUTION:Plural memories Mi are cascaded to form the sorting memory. Data Dx are inputted from the data bus DB to the memory part 11 and the data Dx are transmitted/received through prestage and poststage data lines Si-1, Si. The comparator 12 compares the held data Di with the input data Dx. If Di>Dx, the current data Di is continued to be held, and Di<Dx is formed and Di-1>Dx is YES, the data Dx are inputted and the data Di is transferred to the succeeding stage. If NO, a control part 13 sends signals CNTRL, Ci so that the prestage data Di-1 are inputted. The memories of respective stages process the input data Dx simultaneously. Consequently, sorting can be performed within a short time only by one writing cycle and data can be arrayed in the descending order. If the mark > is turned to <, the arrangement is changed to the ascending order.

Title: Fast breeder reactor without secondary system, and its steam generator
Inventor: KAMEI MITSURU
IPC: G21D1/04
Filed: 1990-02-01
Abstract: PURPOSE:To prevent generated gas from flowing into a reactor core part in case of a break of a heat transfer pipe, and to intend improvement of safety by integrally building an electromagnetic coolant circulation pump part into the down stream side of a heat exchanger part in a steam generator. CONSTITUTION:A coolant sodium Na introduced to a steam generator 20 generates a steam by heat-exchanging with water in heat transfer tubes at a heat exchanger part 24, the heat exchanged Na is sucked by a pump duct 30 and returns to a nuclear reactor vessel by the function of an electromagnetic pump part 26. In very rare case of break of the heat transfer tubes, a huge amount of water and steam flows outside the tubes to cause chemical reaction with the Na and to generate a huge amount of high temperature hydrogen gas which flows into the duct 30. At that moment, the Na cooling a three-phase coil 32 and a fixed iron core 28 at the pump part 32 is removed to bring about an overheat condition and hence the copper in the coil 32 melts away to disable conduction of power thus disabling the pump parts 26. As this pump part 26 has no rotary inertia, transportation of the Na ceases immediately after the break, flowing of the great amount of the hydrogen gas into the reacor core part can be prevented.

IPC: H04B3/03
Filed: 1979-03-02
Abstract: PURPOSE:To omit the hybrid transformer and realize the IC formation by giving the negative feedback control to the current supply side circuit via the output voltage detector provided with connection in parallel to the load and furthermore preventing the detouring for part of the aural signals. CONSTITUTION:The DC current is supplied to load 24 through the functions of power source 25, current supplying current amplifier 20, diving current amplifier 21, output voltage detector 22 and input current supply circuit 23 each. For detector 22 the differential input impedance decreases with increase of resistance ratio R221/ R223 and increases with decrease of the resistance ratio respectively. Thus the coincidence can be obtained between the differential input impedance and the impedance of load 24 by selecting the constant of the circuit element to the proper value. The transmission of the aural signal from the 4-wire side to the 2-wire side is performed through the action in which the input supply current of battery 230 via resistance 231 is modulated by the signal of signal source 28 to be changed into the aural signal. And the extraction of the signal from the 2-wire side to the 4-wire side is carried out via detector 22. At the same time, the signal detouring can be prevented by capacity 31 plus resistances 29 and 30 each.
