IPC: G01C19/56
Filed: 1985-02-16
Abstract: PURPOSE:To enhance detection sensitivity up to the level of shot noise lower by about two figures than heat noise, by detecting the amplitude of vibration excited by Coriolis force by using an optical position detection means based on the interference of light. CONSTITUTION:The titled gyroscope is constituted of a piezoelectric element 10, an exciting means 20 consisting of an oscillator 21, an amplifier 22 and an exciting electrode 23 and an amplitude detection means 30.

Title: Electromagnetic ultrasonic wave converter
Inventor: MIZUNO MASASHI
IPC: G01N29/04
Filed: 1979-03-16
Abstract: PURPOSE: To obtain a light, miniaturized, low-price electromagnetic ultrasonic wave converter by connecting an erase coil to a receiving coil in an opposite phase so as to offset the influence thereupon of the electromagnetic energy of a transmitting coil, whereby the excitation current for an electromagnet is reduced remarkably.  
     CONSTITUTION: An electromagnetic ultrasonic wave converter 1 consisting of an electromagnet 7, a transmitting coil 8, a receiving coil 9, an insulating plate 10 and an erase coil 11 is formed. In this structure the erase coil 11 is connected to the receiving coil 9 such that the coils 11, 9 have 180° phase difference. The coils 11, 9 are connected to an eddy current detection circuit 5 so that the coils 11, 9 offset the influence thereupon of the electromagnetic energy receiving from the coil 8. Accordingly, the offsetting of reflected ultrasonic signals can be minimized in spite of the difference between the coils 9, 11 in the distance from a material subjected to flaw detection and in the signal sensitivity due the difference in the mentioned distance. This structure permits minimizing the excitation current for the electromagnet and reducing a dead zone of a detected wave form. Therefore, the number of areas whose flaws are beyond detection is largely reduced.

Filed: 1993-02-19
Abstract: PURPOSE:To ensure the stable control of a carriage by supporting an objective lens on a optical pickup via a supporting means so that the objective lens can move in the tracking direction orthogonal to the track of an optical disk. CONSTITUTION:The input signal inputted to an A/D converter 18 from a detector amplifier 27 is never saturated in a normal tracking control state. Thus the gain of the amplifier 27 is increased by the control signal GCl of a controller 28. A carriage 14 is controlled also in the normal tracking control state and the gain of the amplifier 27 is increased. Therefore the output data of a small quantization error is inputted to a carriage controller 20 from the converter 18. Then the carriage 14 is controlled in a stable way.
