Title: Gas blast circuit breaker
Inventor: MATSUMOTO EIJI
IPC: H01H33/91
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To prevent a metal foreign matter generated at a slide part on an arc extinguishing chamber side during current interruption from being swept out, adhered, and stayed to the inside by thickening a movable side fixing part of a hollow insulation cylinder, embedding a metal bush, applying a taper to the inside to be nozzle-shaped, and providing a brim at an outer circumference side and fixing it. SOLUTION: A metal bush 9 for mounting an arc extinguishing chamber is embedded in an indication insulation cylinder 1A for insulating and supporting the arc extinguishing chamber from a grounding container, and an arc extinguishing chamber movable side support 2 is tightened with a bolt 8. An inner face of a support insulation cylinder 1A is nozzle-shaped with a taper whose inner diameter is greater toward a grounding side, and tightening with the grounding side is by a brim 11 provided at the outside of the support insulation cylinder 1A. A foreign matter wept out with gas flow from the arc extinguishing chamber during current interruption hardly invades the support insulation cylinder 1A.  If it invades, the foreign matter is not adhered and does not stay in the vicinity of the movable side of the arc extinguishing chamber that is a particular problem on electric field intensity, is swept out to the grounding fixing side, and reliability of the gas blast circuit breaker can be improved.

Title: Control device of vehicle internal combustion engine
Inventor: HIROMOTO KENICHI
IPC: F02P5/15
Filed: 1989-03-23
Abstract: PURPOSE:To execute ignition cut only to a cylinder in which no fuel is present and prevent welding loss of catalyst by sending a current to an ignition plug at following ignition timing only when a valve opening signal is outputted to a fuel injection valve. CONSTITUTION:When a vehicle is made into a determined driving state such as deceleration driving, a fuel cut control means M5 prohibits the output of valve opening signal to a fuel injection valve M1 from a fuel injection executing means M2, and executes fuel cut control. At that time, a judging means M6 provided every cylinder judges whether the valve opening signal is outputted to the fuel injection valve M1 of this cylinder from the fuel injection executing means M2 or not, and when the signal is not outputted, the current sending to the ignition plug M3 of this cylinder executed at following ignition timing by an ignition executing means M4 is prohibited by an ignition cut control means M7. Hence, inconveniences such as welding loss of catalyst and breakdown of ignition plug caused according to fuel cut control and ignition cut control can be completely prevented.
