IPC: F02M69/04
Filed: 1986-09-01
Abstract: PURPOSE:To improve ignitionability and reduce fuel consumption sharply by providing a fuel injection valve in an intake passage near an intake valve, and a squish area inside a combustion chamber. CONSTITUTION:A fuel injection valve 20 to injectedly supply fuel into a combustion chamber 5 is provided near an intake valve 8 on the side of the intake port 6 of a cylinder head 4. A projected part 23 is formed on a part opposite to the inner wall periphery of a cylinder bore 2a on the top of a piston 3, and a squish area 22 on the inner wall periphery of the cylinder bore 2a opposite to the direction of fuel injection from the fuel injection valve 20.

Title: Method of cutting optical fiber
Inventor: SUZUKI ISAO
IPC: G02B6/25
Filed: 1988-08-18
Abstract: PURPOSE:To cut a bare fiber with an exact cutting angle without contact by exposing the fiber in the cutting point and bringing the left part and right part on the front surface of a pressing member into contact simultaneously with the optical fiber on both sides of the cutting point. CONSTITUTION:The exposed bare fiber 12 is scored by a cutting blade 30 at the center of the fiber. Since the position of the cutting blade 30 is fixed in this case, the optical fiber 10 is so set to clamps 20, 22 that the center of the exposed bare fiber 12 and the position of the cutting blade 30 are aligned. The left part 64 and right part 66 of the pressing member 60 come into contact simultaneously with the optical fiber 10 from above a coating part 14 and push down the optical fiber. The stress rupture of the bare fiber 12 is, therefore, resulted by exerting a uniform force to the positions equal from the cutting points p on both sides of the cutting point p. The end faces of the optical fiber which are specular and are nearly perpendicular to the optical fiber axis are easily obtd. in this way.

Abstract: PURPOSE:To prevent a token from being lost by detecting abnormality in a following station with a normal station, which transmits the token, when the token is not received in the following station since a fault is generated, once returning the token to a control station, excepting the following station from a logical ring with the control station and transmitting the token to the new following station. CONSTITUTION:When a token frame is set from a normal station 2 to a normal station 3 and any response can not be obtained, the token is immediately returned to a control station 1. Next, the control station 1 refers logical ring data and sends the token to a normal station 4 which goes to be the new following station. Thus, in comparison with conventional operation, a time to return to normal processing can be shortened. Thus, when the fault which can not to receive the token, etc., is generated in the normal station on the logical ring, the token is returned to the control station 1 and after that, the token is immediately transferred to the new following station. Accordingly, the time to return to the normal operation is shortened.

Filed: 1994-08-31
Abstract: PURPOSE: To reduce the overall size of power supply by constituting a rectifier circuit part only of a diode bridge and feeding only reactive power from an excitation invertor to an induction motor. CONSTITUTION: When an induction generator 2 is not generating power, power is fed from a battery 4 to a drive invertor 5. When the induction generator 2 is generating power, generated power is converted through a diode bridge 3 into DC power and only the reactive component thereof is fed from an excitation invertor 7 to the induction generator and the effective component is fed to the drive invertor 5 and the battery 4. Consequently, the capacity and thereby the size of the excitation invertor 7 can be reduced and since the rectifier circuit part is constituted only of the diode bridge 3, the size can be reduced significantly resulting in reduction of the overall size of a power supply.

Abstract: PROBLEM TO BE SOLVED: To replace lamps with new ones, clean a laminate, and perform maintenance operations long in span by accumulating the action and used time of lighting equipment, and indicating that time having been accumulated, comes up to a set maintenance time. SOLUTION: A set-up inputting part 2 is operated so as to allow each specified value for the replacement time of each lamp and the cleaning time of a luminaire to be set up. The inputting part 2 is formed out of switches, and of a display means such as LEDs and the like, and the inputted specified values are stored in an EEPROM memory 4. Meanwhile, the operating time of the luminaire is accumulated by a real time clock 5 so as to be verified to each specified value stored in the memory 4, and when accumulated time is found to have come up to each prescribed time for the replacement of each lamp or the cleaning time of the luminaire, it is indicated over a display part 7 that replacement time is due, and concurrently a buzzer 8 is sounded so as to allow a warning to be given to controllers.  In this place, the controllers replace each lamp with one stored in advance, or order the lamps for replacement from a store when no lamp is available in stock. When the luminaire has to be cleaned, it is cleaned by the controllers, themselves, or cleaning is relied on outside contractors.

Abstract: PURPOSE:Not only to make a bipolar transistor high in operating speed but also to enhance it in resistance to alpha-rays by a method wherein a potential barrier region to minority carriers is provided between the collector region of the bipolar transistor and a substrate. CONSTITUTION:A potential barrier region 9 to minority carriers is formed between a collector region 10 of a forward bipolar transistor Tr2 and a substrate 1. In the forward bipolar transistor Tr2, as the peak value of the impurity concentration profile of a base region 18 can be accurately set to the junction of it with an emitter region 20 and the accelerating field of electron can be enhanced, a base cutoff frequency is enhanced and an operating speed can be also enhanced. Moreover, minority carriers induced by alpha-rays in the substrate 1 can be prevented from penetrating into a charge storing section 10 by the potential barrier region 9, so that the bipolar transistor Tr2 can be enhanced in resistance to alpha-rays. By this setup, a memory LSI can be improved in resistance to soft errors caused by alpha-rays and high speed operation.

Filed: 1992-08-03
Abstract: PURPOSE:To obtain a highly sensitive high response light receiving element incorporating circuitry by growing a P-type epitaxial layer having high specific resistance in place of a first N-type epitaxial layer having high specific resistance. CONSTITUTION:A first N<+>-type buried diffusion layer 2 is formed in a region for forming a photodiode whereas a P-type buried diffusion layer 4 is formed in a region for forming a signal processing circuit on a P-type semiconductor substrate 1.
