Title: Capacitor for secondary circuit in internal combustion engine equiped with electric ignition system
Inventor: HITOMI KAZUE
IPC: H01G4/002
Filed: 1985-09-20
Abstract: PURPOSE:To increase the electrostatic and electromagnetic energies so as to improve the ignition and combustion efficiency by allowing a secondary circuit to be additionally provided with a capacitor with or without wires for increasing an electrostatic suspension capacity so as to provide an additional proper capacity. CONSTITUTION:A secondary circuit is additionally provided with a capacitor with or without wires by an atmospheric earthing system. With this, an electrostatic suspension capacity is increased by a supplemental effect of a spontaneous generative capacitor component which exists substantially in nature. In this case, if the proper amount of an capacity is additionally provided, capacity discharging which takes place at an ignition plug P.G., is positively and stably effected because of an increase in electrostatic energy, expediting both a flame nucleus forming phenomenon between electrodes of the ignition plug and an ionization of a mixture. And indicative discharging allows a high frequency component of oscillating current at a time of an ignition to be rectified and smoothed, and also allows the disturbance of a spark line in secondary voltage waves to be smoothed out for reducing the unevenness of sparks so as to enable sparks to take place evenly and stably. Accordingly, the ignition and combustion efficiency can be improved.

Filed: 1981-12-24
Abstract: PURPOSE:To obtain a large quantity of elimination with high efficiency and at high speed, by irradiating a laser light pulse to plural arc stages concentric to each other successively at and after the 1st outer circumference stage. CONSTITUTION:Each detector 5 at the root part of each support stand 3 detects the eccentric load of a work 1 as well as the direction of the eccentric load by cooperation with a photosensor 6. Thus the signal corresponding to an operator 7 is obtained. The output of the operator 7 is compared with the signal of a storing circuit 9 to obtain the signal to an operator 10. This signal is led to a laser oscillator 12 and a driving source 13 via a control circuit 11 to perform control. With this control, an arc (a) extending to its both ends on the basis of the direction X-X of the eccentric load is estimated to concentric arcs a1-a11 at and after the 1st outer circumference stage. Then the laser light pulse is irradiated first to the arc a1 and furthermore, to arcs a2, a3... successively by the degree of the eccentric load.

Title: Game machine
Inventor: UGAWA SHOHACHI
IPC: A63F7/02
Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To reduce burden to control related to displaying patterns by a game controlling means without increasing number of commands delivered to a displaying control means even when kinds of changes in patterns are increased. SOLUTION: In a reach (li-zhi) embodiment when there exists re-lottery, there exist a plurality of kinds in lengths of re-lottery periods when left, right and middle patterns are changed again. However, the length of changing period (a timing A) to fixing the whole patterns (a timing C) is definite. Therefore, when e.g. a period for reach motion is increased or decreased to make the period of changing, the length of re-lottery is made variable in cope with it. Even when the lengths of the periods of re-lottery are different, each pattern of motion in the pattern of changing is the same. I.e., even though the time for each pattern of motion during period of changing is different, order of generation of each pattern of motion is the same.

Abstract: PURPOSE:To reduce the loss of a semiconductor wafer caused by removing an abnormal growth part produced when liquid phase epitaxial growth is performed by a method wherein one surface of the semiconductor wafer is perfectly circular and a slop which is in parallel with a cleaving direction or has a certain angle a with the cleaving direction is formed by cutting off a portion between the other surface and the side circumference of the wafer. CONSTITUTION:As far as observing a semiconductor wafer 1 from its surface 8, the wafer 1 is completely circular. On the other hand, observing from the rear, a slope 5 is formed by cutting. The slope 5 is formed by cutting off a portion between the side circumference 6 and the rear 7 and may be in parallel with a cleaving direction (2) or may have a certain angle with the cleaving direction (2). If a thin film is built up on the semiconductor wafer 1 by a liquid phase epitaxial growth method, an abnormal growth part 3 can be very narrow. If the abnormal growth part 3 is removed with a width DELTA, as a removed part 9 is narrow, the remaining effective area of the wafer can be wider. With this constitution, the acceptable area efficiency after the liquid phase epitaxial growth can be improved.
