IPC: H02B13/02
Filed: 1989-02-23
Abstract: PURPOSE:To miniaturize a device by making the end of a bar-shaped charge section arranged in the insulating gas hemispheroidal, forming an insulating layer on the hemispheroid and, at the same time, making the thickness of the insulating layer smaller than about 1/3 of an insulation distance from the hemispheroid to a part of the ground electric potential, and suppressing the maximum field strength to promote insulation characteristics. CONSTITUTION:In an impressed impulse voltage, a distance l between the tip of a hemispherical bar electrode 11 and a metal plate 13 of the ground electric potential is varied to derive an impulse flashover electric potential in that case. The ratio between the thickness t of an insulating layer 12 and a gap length is such that the effect to boost a voltage begins to appear from t/l=30 mm/50mm 1/2, the maximum effect is obtained from t/l 1/3, and about 1.5 times of the voltage rise is obtained. The phenomenon is because that the maximum field strength is suppressed by the effect of the insulating layer 12 having a dielectric constant larger than the insulating gas and, at the same time, that the action to suppress the emission of electron from the hemispherical bar electrode 11 works.

Abstract: PURPOSE:To miniaturize a driving electric power element by providing a means for processing and recording a bit of speed information from trial acceleration and deceleration so as to be the information for controlling the acceleration and deceleration at the time of positioning an actuator afterward. CONSTITUTION:At the time of switching on an electric power source or prior to reseeking in case of a positioning error, etc., a trial of acceleration and deceleration is performed under the state of setting a voltage or electric power to be impressed on the electric power element 20 as a specific value, and that deceleration is processed and then recorded for each individual remaining track to a recording part of a speed instruction generator 2, so as to be used as a deceleration curve for the afterward positioning operation. Since this deceleration curve includes variations of the electric power source voltage and parts related to the positioning, when the afterward positioning operation is carried out by this deceleration curve, the voltage and electric power to be impressed on the electric power element 20 is approximately the same as the trial of acceleration and deceleration, so that the electric power for the electric power element 20 can be restricted. By this method, a speed control is feasible by absorbing fluctuations of the electric power source and variations due to the parts related to the positioning, thus miniaturizing the electric power element 20 for driving a voice-coil motor 6.
