Filed: 1987-01-12
Abstract: PURPOSE:To execute an exact focus control by generating a comatic aberration simultaneously with an astigmatism by an optical system, and eliminating the influence of the comatic aberration by using part of signals obtained at the time of detecting a track error signal, for correcting a focus error signal. CONSTITUTION:A track error signal obtained by a differential amplifier 2' is amplified to a prescribed value by an inversion amplifier 7, and thereafter, in a compensating circuit 8, only a signal of a low frequency band is allowed to pass through by a low-pass filter 9 so that a frequency band by an inclination of an optical disk and a movement of an objective lens can be obtained. Subsequently, a signal with a frequency by an inclination of the optical disk and a frequency by a movement of the objective lens is divided by a frequency filter 10, signals of the respective bands are compensated by phase gain compensating circuits 11, 11', and the compensated signal is applied to a focus error signal. In such a way, subtracting a signal by an inclination of the optical disk or a movement of the objective lens, obtained at the time of detecting a track error signal, from a focus error signal having an offset, a focus error signal containing no offset can be obtained.

Filed: 1989-01-12
Abstract: PURPOSE:To easily and accurately take measure the propagation speed of the surface wave at any measurement site by arranging two vibrators and one vibrator opposite each other across a body to be inspected so that mutually transmission and reception are possible. CONSTITUTION:The vibrators are grouped in, for example, one and two, and one vibrator 6 is used for transmission, and two vibrators 7 and 8 are used for reception. The propagation time in a transmission-side wedge 2 is equal without reference to the distance of the vibrators 7 and 8 for reception and the propagation times in reception-side wedges 3 and 4 are equal because the wedges are at distances from the vibrators 7 and 8 for reception where the propagation times of ultrasonic waves on the abutting surface of the wedges 3 and 4 corresponding to the vibrators 7 and 8 are equal. Therefore, the difference in the total propagation time is equal to the difference in the propagation time of the surface wave propagated in the surface layer of the body 5 to be inspected, and this difference is proportional to the difference in the distance of the propagation of the surface wave. This difference in the propagation distance is divided by the difference in the measured propagation time of the surface wave to find the propagation speed.

Title: Variavle time constant element structure of semiconductor device
Inventor: YAMAMOTO TAKESHI
IPC: H01L27/07
Filed: 1987-01-13
Abstract: PURPOSE:To obtain a small time constant applying a simple structure and a small occupied area, by a method wherein a junction capacitance is varied by changing an inverse bias voltage applied to the junction surface of a diffusion layer and an island. CONSTITUTION:A P-type semiconductor layer 22 is stacked on a P-type substrate 21. On the semiconductor layer 22, an N-type resistance island 28 is formed, and a diffusion layer 24 is formed on the island 23 by P-type base diffusion. The island 25 is connected to high potential via a contact 27. Thus an inverse bias voltage is applied to a P-N junction surface, and the diffusion layer 24 is made electrically independent of other circuits. As the junction surface of the diffusion layer 24 and the island 23 is inversely biased, a junction capacitance is parasitic on the surface. When contacts 25 and 26 are made input output terminals, a diffusion resistance acts as a low-pass filter. Then the junction capacitance is varied by changing the potential of the contact 27, so that the time constant of the filter can be changed, and a capacitor is made practically unnecessary.
