Title: Piston of 4-cycle engine
Inventor: KAJIWARA KENICHI
IPC: F02B75/02
Filed: 1983-11-29
Abstract: PURPOSE:To raise outputs of a 4-cycle engine by gaining quick better combustion states by a method in which walls between recessions are removed and the bottom faces of each recession are connected with smoothened connecting faces in a piston having plural recessions at its top for avoiding interface with a suction valve or exhaust valve. CONSTITUTION:Three suction valve recessions 12a and 12b and two exhaust valve recessions 13 are provided on the top 11a of a piston 11. The walls between two suction valve recessions 12b on both ends of a central suction valve recession 12a and the recession 12a and also the wall between two exhaust valve recessions 13 are removed, and the bottom faces of the recessions 12a and 12b and also of the recessions 13 are connected with the first and second smoothened connecting faces 14 and 15. The interruption of secondary swirl flow in parallel with the top 11a, which occurs during the rise of the piston 11, by said walls can thus be eliminated. Since the secondary swirl flow can be maintained until the following ignition and combustion processes without damping, quick and better combustion of fuel can be attained.

Title: Protecting circuit
Inventor: ISHIKAWA HITOSHI
IPC: G05F1/56
Filed: 1987-09-09
Abstract: PURPOSE:To reduce the power consumption when the output is cut off by using a 1st transistor TR which produces a reference current and a 2nd TR which produces a current accordant with the base-emitter voltage that increases and decreases according to the increase/decrease of the voltage produced at a current detecting resistance and supplies this current to an output control circuit. CONSTITUTION:The bases of PNP TR Q3 and Q4 forming a current mirror circuit 5 are connected in common to each other and the emitters of both TRs are connected to both ends of a current detecting resistance R1 respectively. The TR Q3 has the diode connection, that is, the base and the collector of the TR Q3 are connected in common to each other and the collector is connected to a constant current source which produces a reference current I1. In such connections, the TR Q4 outputs an output control current I2 which increases or decreases in response to the increase/decrease of the current flowing to the R1. Then an output cut-off TR Q5 is controlled by the current I2 and also controls its output with control of an error amplifier 4. As a result, the power loss is reduced.
