Abstract: PURPOSE:To externally detect a flame figure in a combustion chamber by air- tightly providing a seeing through window through which a flame figure is transmitted in the combustion chamber on the side of a penetrated hole and fixing an optical fiber on a side opposite to the combustion chamber on the above side. CONSTITUTION:A penetrated hole to externally propagate a flame figure generated in a combustion chamber 2 is formed on the partition wall 3 of the combustion chamber 2 of a reciprocating internal-combustion engine 1.

Title: Power circuit
Inventor: IMAGAWA KAZUHIKO
IPC: H02M3/155
Filed: 1993-07-16
Abstract: PURPOSE:To provide a reliable DC-DC converter that operates normally even if a power switch is turned on immediately after it is turned off. CONSTITUTION:When a first supply voltage V1 is turned off, the voltage V3 of a capacitor 38 does not decrease due to a Zener diode 37 and a regulator 40 increases the on/off duty ratio of a transistor 41 in order to compensate for a drop of V1. When V1 decreases and becomes equal to V3, both voltages decrease at the same level to the output voltage V2 and then an overload detecting operation is started. A potential of the capacitor 38 increases with the increase in the duty ratio and the regulator 40, when it exceeds a specified potential, outputs a control signal to the transistor 41 to turn it off and then to protect it from overload. When V3 comes to the operation voltage of the regulator 40 or lower, the operation of the regulator is reset and the forced off-state of the transistor 41 is cancelled. By this, output voltage can be supplied even if a power switch is turned on right after that it is turned off.
