Title: Ignition device for internal combustion engine
Inventor: ONO EIJI
IPC: F02P3/04
Filed: 1986-06-24
Abstract: PURPOSE:To effectively prevent smoke, by parallelly connecting ignition coil secondary sides of cylinders, in which a phase is 360 deg. different, in the case of an ignition device which sets an ignition coil in each cylinder. CONSTITUTION:In the cold time, a water temperature signal circuit 21 drives transistors 10a, 10b and 11a, 11b even of an ignition group and no ignition group. For instance, in case of ignition in the group of cylinders #1, #4, an ignition pulse is supplied to the transistors 10a and 11b, but no reverse current is allowed to flow in spark plugs 3-2, 3-3 by diodes 13b, 14b. As shown by a broken line in the drawing, secondary windings 7a, 7b of ignition coils are connected in parallel, further an electric current is allowed to doubly flow in the secondary coil 7a through spark plug electrodes 3-1, 3-4 by setting diodes 15, 16. As a result, good ignitionability is ensured by high increasing a margin for smoke. While the internal impedance in a coil side low decreases by the parallel connection, and ignition required voltage is always generated by low decreasing a voltage drop when the smoke is generated.

Title: Thermal head and manufacture thereof
Inventor: OMORI SEIYA
IPC: B41J2/335
Filed: 1991-05-23
Abstract: PURPOSE:To manufacture a thermal head wherein the useless downward flow of heat generated at a heat generating resistor is minimized by an ordinary manufacturing technique of thermal head i.e., printing technique and burning technique.

Title: Nozzle flapper valve
Inventor: MITO AKIO
IPC: F16K17/30
Filed: 1985-07-05
Abstract: PURPOSE:To enable a high pressure to be controlled in a large bore by a small input, by providing a small hole, which introduces a pressure in the point end surface side of a flapper to an operating oil chamber, in said flapper. CONSTITUTION:An operating oil chamber 24 is formed between a flapper 25 and a rod 27 restricting a movement of the flapper in its moving direction. While the flapper 25 provides a small hole 25b which introduces a pressure in the point end surface side of said flapper to the operating oil chamber 24. By this constitution, a relation of force by the oil pressure is always balanced even if a nozzle back pressure changes because the pressure of oil, introduced to the operating oil chamber 24 from the small hole 25b of the flapper 25, acts on the flapper so as to press it to a nozzle side, thus the high pressure can be controlled in a large bore by a small input.

Abstract: PURPOSE:To cause the warning display on a sensor unit side to be ceased when an informing state is set, by providing a means which selectively sets the informing state for informing of a visitor and another state for informing an abnormal case. CONSTITUTION:A means which switches the direct current to be made to flow to a circuit to a pulse-like current of such a duty that the warning lamp provided in a sensor unit cannot light at the time of informing state, is installed to a crime preventing unit.
