Title: Method of controlling beam diameter and device therefor
Inventor: SUMI KATSUTO
IPC: H04N1/06
Filed: 1996-08-19
Abstract: PROBLEM TO BE SOLVED: To enhance a light utilization efficiency and to eliminate the need for a complex and expensive optical system and zooming system, in a laser diameter control method and device which varies a focus beam diameter of a laser beam. SOLUTION: A part of a laser beam flux is provided with a light path difference longer than a coherence length before being focused. A transparent plate P is provided for giving the light path difference. It is recommended that the laser beam is emitted by a longitudinal multi-mode semiconductor laser with a short coherence length. The transparent plate P may be a parallel plate or a ring form plate positioned in the neighborhood of the light flux. It is recommended that the transparent plate P is put in a parallel beam. It is recommended that the transparent plate P is placed in a parallel beam (collimated beam), however, it may be placed in diverging rays or converging rays. In this case, a light flux quantity divided by the transparent plate P can easily be changed by varying the position of the transparent plate in the direction of the light axis.

Title: Method for detecting position of trouble point of transmission line
Inventor: MORITA AKIRA
IPC: G01R31/08
Filed: 1984-11-07
Abstract: PURPOSE:To reduce the labor before reaching a trouble point, by detecting the position of a trouble point regardless of earth insulating intensity after the trouble of a transmission line was removed. CONSTITUTION:Light is received by a light receiving plate 8 and electric signals respectively outputted from the light receiving elements 8a of said light receiving plate 8 are simultaneously inputted to an erasable memory apparatus 9. A spectrum discriminator 10 discriminates whether the electric signal due to light with a wavelength emitted from a N2<+> molecule is present in the electric signals inputted to the memory apparatus 9, and when it is discrimi nated that the light with said wavelength is absent, the memory content of the memory apparatus 9 is erased. When the electric signal due to the light with the wavelength emitted from the N2<+> molecule is detected in the electric signals inputted to the memory apparatus 9, the memory content obtained at the time of discrimination operation is inputted to a trans mission apparatus 11 to start transmission to the ground. Because this transmission of the memory content is performed in a time series manner corresponding to the number of the light receiving elements 8a of the light receiving plate 8, the coordinates of the position on the light receiving plate of the light receiving element having received the light with the wavelength emitted from the N2<+> molecule is confirmed on the ground.

Title: Operation method of direct injection type gasoline internal combustion engine
Inventor: BAUR BERND
IPC: F02F1/24
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To ensure reliable ignition and combustion of an air-fuel mixture by generating AC voltage by an igniter, generating an ignition spark having a high transformation speed, and charging an ignition coil. SOLUTION: An ignition plug 9 is arranged in a cylinder head 5 so that electrodes 10 and 11 fall within an edge range of a conical jet 7 or an air-fuel mixture cloud 13 by entering a combustion chamber 4 by passing through the combustion chamber ceiling 8. In order to ignite the air-fuel mixture cloud 13, an ignition spark is generated by impressing flashover voltage between the central electrode 10 and the earth electrode 11 connected to the cylinder head 5 from an igniter 15. The igniter 15 generates AC voltage, and transforms necessary flashover voltage, and charges an ignition coil of the igniter. The rapid establishment of high voltage reduces a loss by a resistance shunt circuit by the formation of soot of the electrodes 10 and 11 and an insulator base part 12, and can generate large high voltage. Therefore, a probability of igniting an air-fuel mixture can be enhanced by slight necessary energy.

Abstract: PROBLEM TO BE SOLVED: To surely remove impurity over a long period of time by providing a notch-like peripheral face opening recessed upward from the peripheral edge of a lower end opening on the lower end of a bubbler nozzle, and widening it toward the end with the steepled top. SOLUTION: A circular pipe whose both upper and lower ends are open is used on a first bubbler nozzle 16 inserted by penetrating the upper wall of an upper stage bubbler tank 13 and a second bubbler nozzle 17 extending by inserting the bottom wall of the upper stage bubbler tank. The lower end of the first bubbler nozzle 16 is formed serrated by disposing a triangle in the circumferential direction, a part of the peripheral edge of an end face opening 16a is made a bottom side, and a peripheral face opening 16b recessed upward on a triangular shape, for instance, joins four pieces in the circumferential direction. The lower end side of the second bubbler nozzle 17 is the same. Thereby sample gas becomes fine bubbles, impurity is surely removed, and deposition and adhesion to the inner face of the edge of the peripheral face opening 16b of the separated impurity can be suppressed.

Title: Fuel injector
Inventor: FUJIEDA MAMORU
IPC: F02D3/00
Filed: 1985-10-23
Abstract: PURPOSE:To eliminate insufficient fuel delivery due to influence of pressure control valve by setting specific relation between the delivery of fuel pump and the maximum delivery of injector thus producing pressure for compensating fuel pressure droppage in pressure control valve. CONSTITUTION:The fuel is pressure fed through a pump 15, a filter 16 and a piping 3 to an injector 2. The fuel pressure of injector 2 is controlled through a pressure control valve 17 coupled to the piping 3 to specific level while the fuel discharged from said valve 17 is returned through a piping 18 into a tank. The fuel injected through the nozzle of injector 2 is mixed with the intake air in air supply tube 7 then fed to an engine 11. here, the delivery of fuel pump 15 is set higher than 1.1 times of the maximum delivery of injector 2. Since such pressure as compensating the fuel pressure drop in pressure control valve 17 is achieved, insufficient delivery is eliminated.

Title: Detection of change in computer program
Inventor: DEIBUITSUDO ARAN RATSUDO
IPC: G06F11/28
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To indicate the difference between a changed computer program and its original program by providing a means which extracts the dependence between variables in each program and a means which compares the dependence. SOLUTION: At the time of comparing a first computer program with a second computer program, the input variables of the first program, depending upon which output variables vary, are listed. In addition, the input variables, depending upon which output variables vary, are listed. Then the lists are compared with each other. It is desirable that a dependence extracting means does not extract the dependence between intermediate variables. It is also desirable that the dependence extracting means deletes the dependence between the intermediate variables by performing relation synthesization on a dependent pair. Thus an analysis program can lists differences by comparing dependence relation.

Patent JP-S6297384-A (JP)
Title: Semiconductor laser device
Inventor: SHIBUYA TAKAO
IPC: H01S5/00
Filed: 1985-10-23
Abstract: PURPOSE:To improve the maximum optical output, by forming each layer including an active layer on a substrate, on which two parallel ridges, whose width becomes narrow in the vicinity of an end surface, are formed. CONSTITUTION:Widths WR of ridges 2a and 2b are different in the vicinity of the center (A-A') and in the vicinity of an end surface (B-B') in a laser chip. In this BTRS laser device, the smaller the width WR of the ridges 2a and 2b, the thinner the thickness of a grown film on the ridges. In liquid phase epitaxial growing, the slower the growing speed of an active layer 4, the larger the composition ratio of Al in a crystal and the larger the forbidden band width tends to become. Therefore, the film thickness dB of the active layer in the vicinity of the end surface of the laser chip becomes thinner than the film width dA in the vicinity of the center. As a result, the forbidden band width becomes large only in the vicinity of the end surface. Therefore, laser light emitted in the laser chip is not absorbed in the vicinity of the end surface, and end surface breakdown, which determines the maximum optical output of the laser device, is hard to occur.
