Title: Discharge lamp lighting device and lighting system
Inventor: TAKAHASHI KEIJI
IPC: H01J61/54
Filed: 1994-02-28
Abstract: PURPOSE:To detect the final phase of the service life of a discharge lamp in a simple structure, by detecting the quantity of electricity according to the lamp voltage of a discharge lamp in only the power feeding direction of a DC current, and controlling an electron stabilizing means so as to carry out a protective operation. CONSTITUTION:A discharge lamp 1 is lighted by a high-frequency output in which DC currents are superposed by a DC superposing means B. As a result, a filament to be at the anode side to a DC component is liable to receive a damage by the impact of electrons compared to the other side filament, and is deteriorated rapidly. And, at the final phase of the service life, a half-wave discharge is generated from the filament at the anode side to the other side, and the lamp voltage in this direction is raised. Such a phenomenon is detected by a detecting means C, and according to this output, a control circuit 23 converts the switching cycle of a transistor 7, so as to throttle or stop the high-frequency output. Since a filament liable to be deteriorated is specified, a detecting circuit of the quaitity of electricity can be simplified.

Title: Field effect transistor
Inventor: NANBU SHIYUUTAROU
IPC: H01L29/808
Filed: 1980-03-11
Abstract: PURPOSE:To remarkably improve the surge level resistance with respect to the positive surge in a field effect transistor by increasing the interval of the electrodes between the gate and the source and between the gate and the drain of a gate supply unit wider than those at the other parts of active regions. CONSTITUTION:The intervals between the gate G1 and the source S and between the gate G2 and the drain D of the gate supply unit of a dual gate FET are formed wider than those of the other parts therein. Thus, the resistance of the gate supply unit can be increased, and the concentration of the current thereto can be avoided. Accordingly, it can enhance the surge level resistance of the FET due to the positive surge. The intervals between the electrodes can be thus increased, thereby reducing the gate electrode area of the stepwise mesa and accordingly decreasing the gate resistance.
