Title: Marine engine
Inventor: IKUTA KAZUNARI
IPC: F02K7/02
Filed: 1986-11-13
Abstract: PURPOSE:To prevent the life-shortening of a capacitor due to vibrations from taking place by providing a discharge chamber above a power output chamber retaining the injection water, and then providing the discharge chamber with a discharge circuit which generates an arc discharge between both electrodes therein so that the force of inertia is added in the discharge current direction of the capacitor. CONSTITUTION:A capacitor 7 is filled up by means of a resistance 5 from a constant-voltage power 4, and then, when a fixed voltage is reached, an arc discharge is generated between the main electrode 1a and a power output chamber 2. The arc, which has been generated, moves toward the Glober electrode 1b, and then, at a point of time where the terminal voltage of the capacitor 7 reaches zero, it comes in electrical contact with an arc and is shorted within a discharge chamber 1. Hereupon, the electrical energy of the capacitor 7 passes into a coil 8, and then, it is attenuated as the Joule heat is generated in the discharge chamber 1. Thereby, water in the power output chamber 2 is injected without causing vibrations of the both-ends voltage of the capacitor so that the lifetime of the capacitor can be extended.

IPC: G05F1/66
Filed: 1988-10-27
Abstract: PURPOSE:To eliminate a need of extension of a power receptacle to improve the installation efficiency of vendors by not operating the large-capacity load of one of two vendors at the time of operating that of the other. CONSTITUTION:When the large-capacity load of a first vendor 1 is set to the operating state, a light emitting diode 4 is turned on and a photo transistor 5 of a second vendor 2 is turned on.

Title: Electrostatic recorder
Inventor: TAKEUCHI EIICHI
IPC: G03G15/05
Filed: 1990-10-09
Abstract: PURPOSE:To stabilize formation of a high resolution image by disposing an electrode, applied with a surface layer composed of a material having volume resistivity variable with the intensity of working electric field, oppositely to a recording electrode. CONSTITUTION:A tubular electrode 5 has a double layer structure in which a surface layer 5b is laminated on the peripheral surface of a conductive sleeve 5a. The surface layer 5b is composed of such material as the volume resistivity decreases as the intensity of working electric field increases. Developing field for forming black dots has maximum intensity in the center of the width of recording electrode line and the intensity decreases substantially in symmetrical toward the opposite ends over the width of the electrode. Since the surface layer 5b composed of an dielectric is applied on the tubular electrode 5 at a recording position W, volume resistivity is minimized at a part opposing to the lateral center of the recording electrode line when the developing electric field functions on the surface layer 5b of the tubular electrode and the electric lines of force is converged to the central part of dot thus reducing the radiation angle theta. According to the constitution, a recording image having high resolution can be formed stably for a long term.
