Title: Record eliminating method for optical disk
Inventor: NISHIUCHI KENICHI
IPC: G11B7/30
Filed: 1986-10-07
Abstract: PURPOSE:To contrive to recover the amplitude and noise level of a recording signal by projecting high power laser light and making the width of the molten part of a recording material wider than the time of recording when the recording signal is deteriorated. CONSTITUTION:When a light spot 1 of a high power narrowed up to about 1mum of the wavelength limit of a laser light along a track 3 on a rotating optical disk 1 is irradiated, a temperature quickly rises, a molten point Tm of a material is instantaneously passed through, the heat is spread, quickly cooled and an amorphous condition is obtained. The condition is a reflection factor lower than a crystal condition. When an eliminating light spot 2, which is elliptical and a power density lower than a circular light spot, passes through in the moving direction of a laser beam, a temperature up and a temperature down and smoothly executed, a crystal condition is obtained and a high reflection factor is obtained. When a recording signal is deteriorated, the recording light spot 1, which is a power higher than the time of usual signal recording and is not modulated, and the eliminating light spot 2 are alternately irradiated and recovered. In the condition molten by the laser light irradiation of a non- modulating high power, material composition is equalized, the amplitude and the noise level of the recording signal are recovered and the repetitive life of a material is improved.

Title: Air motor apparatus
Inventor: ARAHORI HARUO
IPC: G01P3/489
Filed: 1984-11-12
Abstract: PURPOSE:To achieve a higher working efficiency and a higher safety margin, by comparing the rotational speed of the spindle with a reference rotational speed to issue a signal based on the results of the comparison. CONSTITUTION:The output from a generator 11 is measured 15 through a waveform shaping circuit 14. The reference measuring time with a counter 15 is determined by the division of oscillation 16 and a control pulse preparation circuit 17 and the measured value is sent to comparators 18-20 separately. Then, the comparators 18 compare the measured values with the upper limit of the proper revolutions set 21 and issues a signal to emit 22 light of blue when the measured value is lower than the upper limit of the proper revolutions. The comparator 19 compares the measured value with the lower limit of the proper revolutions set 23 and issues a signal to emit 24 the light of blue. On the other hand, the comparator 20 in which the maximum revolutions are set 25 to secure the safety issues a signal to emit 26 light of red when the spindle rotational speed exceeds the maximum rotation thereof. Thus, if the diodes 22, 24 and 26 shine blue, the safe condition can be checked.

Title: Dielectric strength measuring instrument and dielectric strength improving method for thin film element
Inventor: KUKI TAKAO
IPC: G01R31/12
Filed: 1989-09-19
Abstract: PURPOSE:To minimize the damage of a measured body and to measure its accurate dielectric strength by applying an AC voltage T which increases in amplitude with time to the body to be measured, detecting a high frequency component which flows and deciding whether or not there is a dielectic break down. CONSTITUTION:The oscillator 4 of a power source part 2 generates the AC voltage which increases in amplitude with time, the voltage is applied to the sample 30 through a voltage cutoff circuit 8, and voltmeters 20 and 22 measure its instantaneous voltage. Then the HPF 12 of a dielectric breakdown detection part 10 extracts only the high frequency component which is generated at the time of the dielectric and a window comparator 16 measures it to detect the dielectric breakdown. Once the dielectric breakdown is detected, its data is fed back to the circuit 8, which cuts off the applied voltage to minimize the damage of the sample 30. At the same time, the instantaneous applied voltage value is measured as a dielectric breakdown voltage. Consequently, one sample is measured repeatedly to measure the dielectric breakdown mode.

Abstract: PURPOSE:To perform highly accurate measurement even in an adverse environment by vibrating a sensor element at the time of non-measurement to shake off dust and a waterdrop. CONSTITUTION:An oscillator 8 repeates alternately an output period wherein measurement is executed and a stop period wherein the measurement is not executed. Based on an output signal outputted from the oscillator 8 in said output period, a sensor signal processing circuit 11 processes a sensor signal from a sensor element 2 and executes a measuring operation. a prescribed time after a fall of the output signal of the oscillator 8, that is, within the stop period of the oscillator 8, a start signal generator 9 generates a pulse signal. Next, a drive signal generator 10 supplies a drive signal to a vibrator 3 to vibrate the same while it is supplied with the output signal from the generator 9, that is, in the stop period wherein the measurement is not executed, and the element 2 is vibrated by the vibration thereof. Accordingly, the element 2 is vibrated forcibly at the time of non-measurement, and by an acceleration generated by this vibration, carbon black or a waterdrop sticking on the element 2 is shaken off therefrom. Thus, an error in measurement is reduced and highly accurate measurement can be executed.
