Title: Lighting device for discharge lamp
Inventor: SUZUKI HIROSHI
IPC: H05B41/24
Filed: 1989-11-24
Abstract: PURPOSE:To improve the switching off function by connecting an unbalanced circuit having impedance greater in the positive bias direction and smaller in the negative bias direction to the base of each transistor of a discharge lamp lighting device of an inverter type. CONSTITUTION:When an AC power 1 is turned on, a start pulse is sent from a starting circuit 4 to the base of a main transistor 9, and an inverter circuit 5 is started. When a preheat current is applied via the filament of the discharge lamp 6 and a resonance condenser 7, resonance is produced between a choke coil 10 and the condenser 7, and a high voltage is applied between the ends of the discharge lamp 6 to light it. Here, a resonance current flows through the primary coil of a current transformer 15 and positively fed back to the secondary coil 17, and a base current flows which current is limited in the positive bias direction by a base resistance 22 and a resistance 23 connected in series to the base of the main transistor 8. The main transistor 8 is quickly turned off in the reverse bias direction by a strong bias caused by an impedance Z2 which is the sum of a resistance 22 and the on resistance of a diode 24 smaller than an impedance Z1. A main transistor 9 functions in the similar manner.

Title: Sensor
Inventor: MURAMATSU HAJIME
IPC: G01P15/02
Filed: 1990-11-16
Abstract: PURPOSE:To enhance reproducibility by shortening the length perpendicular to the axial direction of a casing of a magnet exerting a larger magnetic force to a magnetic ball than that of a magnet exerting a smaller magnetic force, so that the drag the magnetic ball receives from the inside wall surface of the casing can be reduced. CONSTITUTION:When the acceleration of a sensor is zero, a steel ball 20 is situated in a reference position, and the differential output of a differential transformer 25 becomes zero. On the other hand, when the sensor is in a state of acceleration motion, the steel ball 20 receives an inertial force in the reverse direction to the direction of acceleration, and moves in the axial direction of a casing 10 to be away from the reference position. The steel ball 20 moves up to the position where this inertial force balances with the retracting force toward the reference position by permanent magnets 31, 32. As a result, the differential transformer 25 outputs a differential output corresponding to the acceleration. In the permanent magnets 31, 32, in the lengths (the diameters of respective magnetic pole surfaces) perpendicular to the axial direction of the casing 10 of opposite magnetic pole surfaces (N-pole surface of the magnet 31 and S-pole surface of the magnet 32), since the diameter of the magnet 31 is shortened than that of the magnet 32, the drag the steel ball 20 receives from the inside wall surface of the casing 10 is reduced.
