Patent JP-H01167529-A (JP)
Title: Sheath type glow plug
Inventor: KONDO RYOJI
IPC: F02P19/00
Filed: 1987-12-21
Abstract: PURPOSE:To achieve improvement in durability of the title plug by inexpensive means, by a method wherein a sealing member made of a resilient material, which adheres closely to a metallic tube due to the resiliently repulsive force of the material itself and is less pervious to N2, is disposed in a position where the external air coming into the metallic tube can be shut off. CONSTITUTION:A heating resistor 1 repeats its heating and cooling due to an electric current flowing thereto. However, the use of a sealing member 8 made of a resilient material, which is less pervious to N2, permits only the extremely small amount of N2 in the air to pass through the sealing member 8 and come into the portion of the heating resistor 1. Accordingly, even if the temperature of the heating resistor 1 becomes high, the formation of AlN is extremely reduced owing to the presence of the remarkably small amount of N2, whereby the embrittlement and the wire breakage of the heating resistor 1, which are caused by the formation of AlN, hardly occur. As a result, a sheath type glow plug is markedly improved in durability, and furthermore, since the sealing member 8 made of a resilient material available at a low cost is used, said plug can be produced inexpensively.

Title: Voltage doubler type charging circuit
Inventor: OKAMURA KATSUYA
IPC: H02M9/04
Filed: 1990-11-28
Abstract: PURPOSE:To establish discharge stably without causing after voltage on a load by discharging one capacitor, when series connected capacitors are charged reversely with energy reflected from the load, and discharging the other capacitor through a series circuit of a diode and a resistor. CONSTITUTION:A series circuit of a diode 14 and a resistor 15 is connected in parallel with a capacitor 12 such that the diode 14 initially blocks discharge of charging voltage. When a current flows through a load, residual charges are fed from the series capacitors 11, 12 to the load but since impedance matching is not established between the circuit and the load, the series capacitors 11, 12 are charged reversely. Consequently, the capacitor 12 is discharged quickly through the diode 14 and the resistor 15 thus discharging the capacitor 11 while oscillating through a high speed switch 20.
