Title: Method and equipment for driving ultrasonic motor
Inventor: HONDA YASUYOSHI
IPC: H02N2/00
Filed: 1995-07-05
Abstract: PROBLEM TO BE SOLVED: To make it possible to change rotary torque of an ultrasonic motor rapidly and smoothly. SOLUTION: As shown by Figure, rotary torqueτ generated in an ultrasonic motor changes with a change in a phase difference θof driving signals of two phase to be supplied to the ultrasonic motor. Therefore, a gradient α of a change in rotary torque against the change in a phase difference is measured and at the same time, a deviation in a phase difference β is also measured. The deviation in a phase difference β is a difference between a phase difference when the rotary torque reaches a specified value when the phase difference is so changed that the rotary torque in a certain direction may increase and a phase difference when a rotary torque reaches the specified value when the phase difference is so changed that the rotary torque in a certain direction may decrease. For controlling the rotary torque of the ultrasonic motor, a phase difference θ is found using a formula θ=1/α.τT+β/2 when a target value τT (a positive value in the clockwise direction and a negative value in the counter clockwise direction) of the rotary torque tends to increase, and using a formula θ=1/α.τT-β/2 when the target value tends to decrease, and thereby a phase difference between the driving signals of two phase to be supplied to the ultrasonic motor is agreed with the phase difference θ.

Title: Circuit substrate
Inventor: YASUMOTO YASUAKI
IPC: H05K3/46
Filed: 1989-06-30
Abstract: PURPOSE:To make circuit patterns come closely, favorably into contact with an AlN substrate and an AlN thin film by providing repeatedly the circuit patterns having multilayer structure consisting of a metal layer and a metal nitride layer and an aluminum nitride thin film having prescribed compositions on an aluminum nitride substrate having the prescribed composition. CONSTITUTION:For example, circuit patterns 2, 5, 9, and 3 having: a metal nitride layer which is expressed by MxNy (M represents Cr, Ti, Ta, W, Zr, Hf, Mo, Nd, Ni, and further x and y indicate integers which are determined according to values of M and N); a metal layer consisting of M; a Cu layer; and multilayer structure made up by the metal layer consisting of M and the metal nitride layer as well as AlN thin films 4, 8, and 12 in which the content of oxygen reaches 0.005-30atomic% are provided repeatedly on an AlN substrate 1 in which the content of oxygen reaches 0.005-30atomic%. If the content of oxygen is 0.005atomic% or less, internal stress at a boundary layer between the AlN thin films and the circuit patterns is not relieved sufficiently and no circuit patterns which are superior in adhesion to an AlN substrate and the AlN thin films are formed. On the other hand, if the content of oxygen exceeds 30atomic%, the ratio of Al2O3 containing in the boundary layer increases and then, the circuit patterns are liable to peel off from the AlN substrate and the AlN thin films.

Title: Information recorder
Inventor: SUZUKI KATSUMI
IPC: G11B7/135
Filed: 1989-06-30
Abstract: PURPOSE:To make a recording spot and a reproducing spot on an information recording medium smaller and hence to enable high density recording by recording and reproducing information with a light beam obtained by superimposing a fundamental wave emitted from a laser light source and its n-th higher harmonics. CONSTITUTION:The subject device is composed of an n-th higher harmonics generator 2 for converting one part of the fundamental wave emitted from the laser light source 1 into the n-th higher harmonics and an optical system for convergently irradiating the information recording medium 10 with the light beam of the laser light source 1. Then, the information is recorded and reproduced by the superimposed laser beam of the n-th higher harmonics from the n-th higher harmonics generator 2 and an unconverted fundamental wave. Consequently, the superimposed light beam of the fundamental wave emitted from the light source and n-th higher harmonics is smaller than the fundamental wave in wavelength. By this method, the recording spot and the reproducing spot can be smaller than before, and hence the recording density can be promoted.

Moreover, complementary input signals A, A' are inputted to the bases of TRs Q3, Q6. When the clock CK is at a high level, a same potential Vcc-V1/2 appears at the nodes nu1, nu2 and when the clock CK is at a low level, an ECL logic signal appears at the nodes nu1, nu2 depending on the inputs A, A'. Thus, the transfer of data by the clock without series gating. As a result, a high voltage source Vcc is made close to a low voltage source Vss and the lower limit of the power voltage is sufficiently made small.

Abstract: PURPOSE:To easily change a probe and a sample by providing a base and a vibration eliminator, a fixing mechanism for fixing the base at a constant position, etc. CONSTITUTION:A lever 13 is pressed by a driving shaft 18 to turn around a fulcrum 13a. As this lever 13 rotates, a coupling rod 15 which is engaged between the lever 13 and the force point P of a lever turns the lever 16 around a fulcrum 16a. Consequently, cut parts 4a and 4b formed in end parts of the base 4 are pressed by pins 14 and 17 provided at the operation points of the levers. At this time, the base 4 is pressed by the pins 14 and 17 toward the bottom plate of an observation chamber 1 to press the vibration eliminator 12 arranged between the bottom plate and base 4 toward the bottom plate of the vibration eliminator 12, so the operation of the vibration eliminator 12 is suppressed and the base 4 is fixed at the constant position. Then a probe socket 6 and a sample holder 9 are changed at the position where the base 4 is fixed.
