Title: Manufacture of semiconductor photodetector
Inventor: AISAKA FUKUNOBU
IPC: H01L31/107
Filed: 1980-08-28
Abstract: PURPOSE:To form a guard ring in a step of diffusing at low temperature for a short time by selectively removing a semiconductor layer forming the surface of a semiconductor photodetector prior to the step of diffusing impurity. CONSTITUTION:An n type InP buffer layer 2, an n type InGaAs layer 3, an n type InP layer 4, and an n type InP layer 5 are sequentially formed on an n<+>-type InP substrate 1. Then, an SiO2 film mask 6 is formed on the layer 5, and the layer 5 not with the mask 6 is removed by a selective etching. After the mask 6 is separated, a diffusing mask 7 is formed, Cd is diffused in the layers 4, 5 to simultaneously form p<+> type InP regions 8, 9. The region 8 becomes a  guard ring, and the region 9 becmes a photodetector. Since the formation of the guard ring can be accordingly formed in the step of diffusing at a low temperature for a short time, it can reduce the crystalline defects, thereby obtaining a stable avalanche breakdown.

Title: Picture signal correcting method
Inventor: MATSUMOTO MASAYUKI
IPC: H04N1/409
Filed: 1984-06-09
Abstract: PURPOSE:To suppress the influence of noise included in a picture signal to be exerted on a finally corrected picture signal by dividing picture information of each picture element in a window using a proper divisor before addition of the amount of correction S. CONSTITUTION:Dividers 8a-8p are interposed between gate circuits 6a-6p and an adder 7. Digitized picture information inputted to the adder 7 is divided by a proper divisor by dividers 8a-8p. Thereby, lower rank bits of digitized signals representing the picture information are removed, and influences of fluctuation of lower rank bits due to influences of noise on the added value is prevented. When calculating the amount of correction S using picture information amm of central picture element, considering that the number of picture elements in the window is (n)X(n), information amm is multiplied by n<2> in the multiplier 17, and this n<2>Xamm is sent to a latch circuit 18. A signal SIGMA of the latch circuit 13 and n<2>Xamm of the circuit 18 are added by an adder 19 (actually, operation of n<2>Xamm-SIGMA is performed) and the amount of correction S is obtained.

Title: Fuel injecting pump
Inventor: SENDA JIRO
IPC: F02M59/26
Filed: 1986-05-22
Abstract: PURPOSE:To have reduction of combustion noise in low-speed operating range and holding of the combustion characteristic in the high-speed operating range simultaneously by forming a throttle flowout passage at a plunger. CONSTITUTION:At the periphery of the top of a plunger 3, a throttle flowout passage 13 is formed which is in communication with a lead 11 and allows the fuel to flow out in throttle state in the condition in communication with a barrel port 10. In low-speed operation, fuel flowout is made smoothly through said throttle flowout passage 13, so that two-staged injection consisting of a fore stage and after stage is obtained, i.e. a fore injection to be made till the barrel port 10 being put in communication with the flowout passage 13 and a main injection to be made from said communication being shut off till the barrel port 10 to be put in communication with said lead 11. In high-speed operation, on the other hand, fuel flowout via throttle flowout passage 13 is suppressed, which reduces drop of the fuel pressure while the barrel port 10 is in communication with the throttle flowout passage 13, to lead to accomplishment of single-staged injection free of interruption of the injection.

Title: Data communication system
Inventor: YASUDA NOBUO
IPC: H04L29/08
Filed: 1984-06-12
Abstract: PURPOSE:To prevent the generation of a drop-out at the reception side by transmitting again the character preceding an error character in case the error character is equal to a canceling character when a collation error is detected at a transmission terminal. CONSTITUTION:A transmission terminal Ti compares successively a transmission data train with a reception data train while transmitting an output data train and decides a transmission error in case no coincidence is obtained from said comparison. If the pattern of an error character CH is not equal to the pattern of a canceling control character, the canceling character is added after the error CH. Then the data train subsequent the error CH is transmitted again. When the coincidence is obtained between the pattern of the error CH and that of the canceling character, no character is added and the data train is transmitted again at and after the CH which precedes the error CH by one step. Thus such a case is avoided at a reception terminal that characters are continuous within a reception data train. This can avoid a drop-out of a received telegram that is disused unnecessarily. Thus the reliability is improved with data communication.

Filed: 1984-06-12
Abstract: PURPOSE:To shorten access time and to improve durability of clutches by dividing an output of an electric motor into two systems, disposing a long-cycle digital solenoid clutch in one system and a short-cycle digital solenoid clutch in the other system, and adding outputs thereof to be output. CONSTITUTION:A digital solenoid clutch comprises an electromagnet 8, and a roller 2 mounted on an arm 4 turned around an output shaft 4a, which is adapted to conduct friction gearing between the output shaft and a shaft 1a of an electric motor. Two sets of the clutches are disposed between the shaft 1a of the electric motor and the output shaft 4a. In this arrangement, when a continuous output is required, one clutch adapted to connect and disconnect in a long cycle is used to output, and the other clutch adapted to connect and disconnect in a short cycle is used at the time of obtaining output with high accuracy. Therefore, if both clutches including normal and reverse rotations are suitably combined to output, it is possible to output with the shortest access time.

Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To suppress the power consumption of a reading means to the minimum by making the reading means read assigned identification data by providing an identification card carrying the data to a user, and when the reading means does not read the identification data for a fixed period of time or longer, prolonging the reading time intervals so as to make the reading means read the data at the new reading time intervals. SOLUTION: An IC card unit 54 is actuated intermittently at time intervals of 100 ms in a standby state, and when a peculiar IC card 32 is not able to be recognized even when a prescribed period of time has elapsed from then, the IC card unit 54 is actuated intermittently at time intervals of 500 ms. When the characteristic IC card 32 is still not unable to be recognized, a standby stopping state is set. As a result, the power consumption of the IC card unit 54 can be suppressed, and accordingly, the electric power of a battery 16 can be saved. Thus, an electric vehicle is started to run after the user of the vehicle rides in it.

Title: Screen printing method
Inventor: NISHIKAWA NOBORU
IPC: B41F35/00
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To automatically perform a solidification-prevention of a solder on a mask, without the reduction of a productivity and a loss in the working man-hours, and improve the quality by reducing the viscosity of the cream solder on the screen mask by reciprocating a squeegee a specified number of times when a stop period of time of the squeegee becomes a specified value or higher. SOLUTION: After a start, when there is no operation interruption of a screen device at #2, whether a printing is continued or not is checked by #8, and at the time of a printing continuation, the process returns to #2. At the time of an operation interruption at #2, a counting of a squeegee stop period of time is started at a timer section, and when the squeegee stop period of time exceeds a set value, the arrival of a next carried-in base is waited, and a solder is mixed and kneaded by reciprocating a squeegee a set number of times at #6, and the solder which is beginning a solidification while the squeegee stops is softened again, and a printing with the cream solder on a screen mask is performed.  When the reciprocation of the squeegee reaches the specified number of times, the squeegee returns to a set reciprocating motion for a normal printing, and when the printing is not continued, the printing is finished. By this constitution, the solidification of the solder on the mask is automatically prevented from occurring, and the efficiency and the quality can be improved.
