Title: Optical pickup device
Inventor: HIRAI HIDEAKI
IPC: G11B7/095
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To eliminate the vibration of an objective lens and to reduce the access time by outputting positioning signals while passing a d.c. component included in a track error signal and switching the control signal of the lens to positioning signal from the track error signal during a seek. SOLUTION: A positioning signal generating section 16, comprising a low pass filter, passes a DC component of a track error signal TE generated in a track error signal generating section 14 to obtain positioning signal LP. During a seek, a switch 18 whites the output of a subtractor 17 to a tracking control section 10 for an inputting. When a seek is started, sine wave-shaped track error signal TE is outputted at the output of the section 14. However, the sine wave components are eliminated by the low pass filter of the section 16 and only a DC offset signal is outputted. The DC component is transmitted to the section 10 by the switch 18 and therefore, no vibration exists at an objective lens 5 and it is accessed immediately after the completion of a seek.

Title: Starting circuit for inverter
Inventor: NAKAMURA TOMOHARU
IPC: G05F1/67
Filed: 1984-09-07
Abstract: PURPOSE:To utilize facilities effectively by using one inverter to start another inverter. CONSTITUTION:Direct-current electric power generated by a battery stack is converted by two inverters 3 into AC power, which is supplied to an electric power system 5 through a boosting transformer 4. During this battery stack actuation, the lower-side inverter is used as a rectifier so as to supply a minimum operating current to the upper-side inverter and holds the stack voltage constant. When the actuation is finished, the inverter is changed in polarity by a polarity switch 11 and used as an inverter to supply electric power to the system. In this case, a detected voltage is inverted in polarity for a lower- side converter, so the output of a constant voltage control circuit 16 is saturated to a small side. Consequently, a constant current control circuit 14 is selected and the output of the battery operates as a constant voltage source in the system; and the two inverters perform independent current control to convert the output of the battery into AC electric power according to a set value.

Title: Apparatus for detecting speed and acceleration
Inventor: NAKAZAWA KOICHI
IPC: G01P15/00
Filed: 1989-07-19
Abstract: PURPOSE:To accurately detect the speed at the sampling point of time in a state reduced in time delay by dividing the quantity of rotation of a motor per one pulse of an encoder by the pulse cycle of a signal most reduced in time delay to calculate a speed. CONSTITUTION:When an interruption signal pulse is inputted to a CPU 31 at a definite interval from a sampling timer 4, the CPU 31 executes the processing procedure preliminarily stored in a program memory 32. An encoder 2 generates the pulse of the multiphase signal pulse proportional to the quantity of rotation of a motor 1 and a cycle measuring means 5 measures the pulse cycle of said multiphase signal and that of the reversal signal thereof. Measuring means 5 detects the rotary direction of the motor from the generation order of the pulses of the respective multiphase and reversal signals and divides the quantity of rotation per one pulse of the encoder 2 by a pulse cycle most reduced in time delay to calculate a speed. As a result, the error of speed data is reduced and speed controllability can be enhanced.

Title: Flaw detection apparatus
Inventor: ISHIHARA KOJI
IPC: G01N29/04
Filed: 1985-08-26
Abstract: PURPOSE:To make it possible to certainly detect a flaw even if no coupler is used, by providing a surface wave generation means and a flaw measuring means. CONSTITUTION:When the compressed gas accumulator 13 of a surface wave generation means 10 is driven, compressed gas is injected and controlled by a compressed gas control system 14 to allow a needle 12 to act. By this mechanism, the needle 12 performs piston motion by the pulsation pressure of the compressed gas in an air gun 11 and the energizing force of a spring 15. Subsequently, the leading end of the needle 12 impinges against the surface of an object 1 to be inspected at the N-position thereof to excite a first surface wave R1 in the object 1 to be inspected. When the surface wave R1 advances to reach a flaw 2, said surface wave R1 is reflected from flaw 2 to advance as a second surface wave R2. At the same time, laser beam S is outputted from a laser oscillator 18 and passes through a beam splitter 19 and an interferometer 20 to irradiate an A-position. By this method, the flaw can be certainly detected even if a coupler is not used.

In the circuit 34, a level of the peak value is controlled, and its output controls the amplifier 31 through a peak detector 36. Also, the other output of the circuit 34 is inputted to a DC high voltage generator 32, the APD30 is biased by its output, and the multiplication of the APD30 is controlled. In this regard, as for the detector 36 and the high voltage generator 32, their time constants are almost equal, therefore, the controlling circuit of multiplication of the APD30 and the controlling circuit of gain of the circuit 31 are not operated at the same time.
