Title: Combustion chamber for collision diffusion type diesel engine
Inventor: YAOITA YASUHITO
IPC: F02B23/04
Filed: 1993-03-01
Abstract: PURPOSE:To mix air and burnt gas into fuel jet on a collision surface to improve volatility and diffusibility of the fuel jet to reduce smoke, by arranging another collision surface smaller than the collision range of the injection fuel, in a collision surface peripheral part on a piston in a combustion chamber. CONSTITUTION:In a collision diffusion type combustion chamber in a diesel engine, a second collision surface 2 and a collision surface 3 are arranged, in order from a nearer side to a fuel injection valve 1, on a piston in the front in a fuel injection direction by the fuel injection valve 1. A link part 4 and a narrow space are arranged between both the collision surfaces 2 and 3. An air chamber 6, having an opening part 5 in the center part of the collision surface 2, is formed on the inside of a collision part 7. Moreover, the second collision surface 2 is set equal to or more than the opening part 5 so as to prevent the direct flow of injection fuel into the opening part 5, and also smaller than the collision range of fuel. On one hand, the collision surface 3 is set larger than the collision range of fuel. Consequently, air and burnt gas can be mixed into the fuel jet in the collision surface 2.

IPC: H02P29/00
Filed: 1986-04-04
Abstract: PURPOSE:To reduce the variation of the rotating speed of a motor due to the detecting error of a rotation sensor in a speed controller for a motor by detecting the speed of the motor on the basis of the output of the sensor, and producing a control signal on the basis of detection signal values of predetermined times. CONSTITUTION:An AC signal of a period responsive to the rotating speed of a motor 1 is generated by a rotation sensor 2, and input to a speed detector 3. The detection signal of the detector 3 is input to a compensator 4 to produce a control signal. The compensator 4 has a calculator 5, a memory 6, and a D/A converter 7, and produces a control signal on the basis of the detection signal of the detector 3 by a signal combined with a new detection signal value of the detector 3 and the detection signal value of previous time. This signal is input to a driver 8.

Title: Retraction/extension apparatus for triangle sail
Inventor: YAMANAKA KAZUO
IPC: B63H9/06
Filed: 1981-05-26
Abstract: PURPOSE:To facilitate retraction/extension of a triangle sail without laborious work by using a rotatable mast and a winch. CONSTITUTION:In order to retract a triangle sail, a worm 5 turns to rotate a mast 1 and the winch 14 is made free to deliver a wire rope 15. As a result, the triangle sail 13 is wound around the mast 1 to be retracted. While, in order to extend the sail 13, the worm 5 turns reversely to rotate the winch 14. Consequently, the end portion 13' of the triangle sail 13 is pulled by a wire rope 15 and the sail 13 is wound back from the mast 1, extending the sail. During the extended condition of the sail, suitable tension can be always applied to the triangle sail 13 by means of the winch 14.

Title: Multi-color recording method
Inventor: TANAKA TAKESHI
IPC: G03G15/01
Filed: 1986-04-05
Abstract: PURPOSE:To obtain good color reproducibility even with a toner image by using a pulverized particle toner having <=7mum average grain size and specifying the surface roughness of the half toner image part after fixing to <=8 cycles/mm ruggedness frequency and <=9mum amplitude. CONSTITUTION:The color of the toner image can be made as good as the color by offset printing simply by controlling the surface roughness in such a manner that the product of the ruggedness frequency and amplitude attains <=0.072. The toner particles having 10-15mum average grain size are usually required to be adhered to each other by exerting heat or pressure to the toners in order to smooth the image surface until said value is satisfied. An offset arises and the fine lines are thickened to deteriorated the image quality if the heat and pressure are excessive. The average grain size is, therefore, selected at <=7mum, and the average roughness at 10 points is controlled to <=9mum and the ruggedness frequency to <=8 cycles/mm. The irregular reflection on the toner image surface is then decreased, by which the color deviation by the decreased saturation and lamination is prevented and the high-quality multi-color image by the toner image is obtd.

Title: Electrostatic induction transistor logical device
Inventor: NAKANO TAKAO
IPC: H01L27/02
Filed: 1978-06-28
Abstract: PURPOSE:To improve a high-speed property and the efficiency of power, by decreasing junction capacity while preventing the injection of a small number of unnecessary carriers. CONSTITUTION:Ranges 22, 11, 132 form a PnP transistor Tp that employs each range as an emitter, a base and a collector.

Title: Rotor of magnetic generator
Inventor: OYAMA MIYUKI
IPC: H02K21/22
Filed: 1994-03-25
Abstract: PURPOSE:To adequately mount a magnet to a yoke where a reluctor is expansion-formed while avoiding a decrease in inner radius. CONSTITUTION:In a rotor of a magnet generator where a plurality of arc-shaped magnets 20 are located at regular intervals within the inner periphery of a yoke where a reluctor is expansion-formed in a part of a cylindrical wall outside the radial direction, a radius Ra of a central portion 22a in peripheral direction of the outer periphery of each magnet is set larger than a radius ra of the inner periphery of a yoke cylindrical wall 12, and a radius Rb of both the ends 22b in peripheral direction is set smaller than the radius ra of the inner periphery of the yoke cylindrical wall. By doing this, if the roundness of the yoke is degraded due to the expansion of the reluctor, then the central portion 22a at the outer periphery of the magnet always comes in contact with the inner periphery of the cylindrical wall of the yoke, so that the magnet is not deviated to the center direction of the yoke. Since the inner diameter of a group of magnets is not reduced, interference of the rotor with the stator of generator can be avoided and thus it is not required to make an air gap larger between the rotor and stator of generator.

Title: Pinball game machine
Inventor: UGAWA SHOHACHI
IPC: A63F7/02
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To provide a pinball game machine capable of shortening time required for dispensing continuous prize balls concerning the pinball game machine for switching the destination of ball dispensation to ball lending and prize balls by providing a ball dispensing passage with a passage switching means. SOLUTION: When a prize winning ball is detected before completely dispensing prize balls corresponding to one time of transmission of a prize ball dispense signal, without waiting the end of the dispensing operation of prize balls, a game control substrate transmits the next prize ball dispense signal to a dispensation control circuit board and when a prize winning ball is detected and ball lending is not requested before completely dispensing prize balls corresponding to one time of reception of a prize ball dispense signal (SS 13b), the dispensation control circuit board performs control so as to continuously dispense the next prize balls. Thus, since the next dispensing operation of prize balls is started just after the preceding dispensation of prize balls at the time of continuous prize balls, the time required for dispensing the continuous prize balls can be shortened.
