Filed: 1979-10-26
Abstract: PURPOSE:To reduce the power consumption and to make stable the oscillation, by providing a capacitor of AC coupling between gates of P channel MISFET and N channel MISFET constituting an amplifier circuit. CONSTITUTION:To follow the gate bias of an amplification MISFETQ3 provided at the power supply line A of an oscillating circuit against the variation of the power supply voltage due to the change in the output voltage by a power supply switching circuit 4, a high resistance R4 is provided in parallel with a capacitor C0. When the voltage on the power supply line A is decreased and MISFETQ4 for bias turns off, the resistance R4 forms a discharging path to a coupling capacitor C0. Since the gate voltage of a driving MISFETQ3 follows a voltage change is comparatively short time, it can sufficiently follow the feedback signal fed via the coupling capacitor C0, allowing the oscillation circuit to stably be in oscillation operation.

Title: Open-close burner utilizing coefficient of expansion
Inventor: SHIBATA KANAE
IPC: F23D11/38
Filed: 1984-07-05
Abstract: PURPOSE:To prevent a gas leakage by opening or closing a valve by making use of the differential coefficients of expansion. CONSTITUTION:Since the present burner has a construction in which the heat at the time of ignition starts the discharge and burning, the gas leakage is automatically stopped as the heat dissipates when the burning is ceased for any reason. The outer casing 1 and a nozzle port A which are made of material having a high coefficient of expansion are subjected to a compound expansion of the cubical and linear expansions by the heat of ignition to cause a rod valve 2 made of material having a low coefficient of expansion to separate from the tight contact area 4 with a valve retainer screw 3 due to the differential expansion, and the gas flows from the gas inlet B to the nozzle port A to be burnt. When extinguished, as the temperature of 1 and A is lowered, the thermal expansion is lost to cause the valve to be closed, and the gas discharge is stopped.
