Title: Method for controlling drive of cylindrical coordinate robot
Inventor: KOBAYASHI MASAKAZU
IPC: B25J9/04
Filed: 1992-03-24
Abstract: PURPOSE:To provide a control method capable of highly accurately determining the driving output of a cylindrical coordinate robot over the whole areas. CONSTITUTION:A CPU 511 judges whether the posture (zenithal angle) of a teaching point or an interpolation point is in a specific area or not. When the posture is outside the specific area, the CPU 511 calculates the strict solutions of a quaternary equation for the cosine of an intersecting angle and then calculates the angle of turning from the solution. When the posture is in the specific area, the angle of turning is calculated from the strict solution of a quaternary equation for the reciprocal of the cosine of the intersecting angle. In addition, the CPU 511 determines other driving variables from the angle of turning, calculates driving signals D1 to D5 and transmits the signals D1 to D5 to driving mechanisms 531 to 535 through a data bus 57. Consequently the tip of a torch is accurately moved to the teaching point or the interpolation point.

Title: Reproducing device of information recording disc
Inventor: HIRASAWA KAZUO
IPC: G11B7/09
Filed: 1983-06-01
Abstract: PURPOSE:To prevent the malfunction of a control loop due to a false control signal by providing a limiter circuit, which clips a control signal having a specific frequency range with a prescribed value, in the control loop of an optical disc device. CONSTITUTION:Limiter circuits 26 and 27 inserted to a track following-up control loop and a focus control loop respectively show limiter characteristics for high ferquency components but do not show limiter characteristics for high frequency components but do not show limiter characteristics for low frequency components. In case of surface shake or eccentricity of a disc, the relation between an essential control voltage Vt and a false control voltage Vf is shown by Fig. Since the frequency components of the voltage Vf are very higher than those of the voltage Vt, they can be discriminated with respect to a band. The clipping operation indicated by clip levels E1 and E1' is performed for the discriminated high-frequency false control voltage by a clipping circuit. Thus, the clipping of the essential control voltage is avoided to perform the sufficient clipping operation for the false control voltage Vf.

Title: Piezoelectric vibrator and its production
Inventor: SUGIMOTO MASAHITO
IPC: H03H9/17
Filed: 1997-04-16
Abstract: PROBLEM TO BE SOLVED: To suppress the spurious by preparing two piezoelectric single crystal plates which are unified together in the direction, almost opposite to the axial direction of spontaneous polarization and the drive electrodes which are formed opposite to each other on both main surfaces of those two single crystal plates that are bonded directly to each other. SOLUTION: Two sheets of piezoelectric single crystal wafers 11 and 12 are made of lithium niobate and have the same thickness with directions of polarization Ps shown by arrows respectively. These wafers 11 and 12 are bonded directly to each other in a single body. Then the drive electrodes 13 are formed on the upper and lower surfaces inverted polarization wafers 11 and 12 bonded to each other. Thus, an energy containment-type piezoelectric vibrator is obtained. When the wafers 11 and 12 are bonded to each other, the bonding surfaces of both wafers 11 and 12 are polished into mirror-finish surfaces and cleaned and undergo hydrophilic treatment. Such two wafers are touched with each other and then heated. From this, both wafers 11 and 12 can be directly bonded to each other at an atomic level without the use of any adhesive whatsoever.  Therefore, the elastic loss is very small, when a bulk wave is transmitted. Thus, the mechanical quality counting Q and quality are improved for the vibrator.

Filed: 1988-04-22
Abstract: PURPOSE:To reduce the occurrence of disorder accompanied with the switching operation by switching a time constant of phase synchronization to form a gentle slope at the time of switching from the quick lead-in state to the normal synchronous state. CONSTITUTION:When switching from the quick lead-in state to the normal state is indicated, the output voltage of a voltage comparator IC 2 of a time constant switching controller 4 falls and the voltage of a time constant switching signal S6 falls while describing a gentle slope. Consequently, the circuit between the drain terminal and the source terminal a field effect transistor Q1 of a filter 2 is turned off, and the resistance value between them is raised. Then, the time constant of the filter 2 is changed to the value by which the eliminating integral capability of high frequency components is increased, and the normal synchronous characteristic is realized as the whole of a phase synchronizing circuit.

Title: Semi-plane type josephson junction device
Inventor: SHINADA MEGUMI
IPC: H01L39/22
Filed: 1990-04-16
Abstract: PURPOSE:To improve the yield of manufacture and device characteristics in a semi-plane type Josephson junction device by forming a metal thin film having a proximity effect between an insulating layer and a second layer superconduction thin film. CONSTITUTION:A first layer Nb thin film 2 is formed on a substrate 1 such as Si and an insulating layer 3 formed on the former. A metal thin film 6 such as Au is formed on the layer 3 in a thickness less than the one where the film 6 becomes a superconduction state by the proximity effect. Herein, the film 6 can be formed by resistance heating evaporation, etc., and does not damage the layer 3. Then, a second layer Nb thin film 4 is formed on the film 6 by sputtering, and the layer 3 is thereupon protected by the film 6 and is not damaged. Finally, a third layer Nb film (bridge) 5 is formed to yield a semi-plane type Josephson junction device. Upon operation, the film 6 becomes a superconducting state by the film 4, and a bridge length is determined by the thickness of the layer 3. Thus, the layer 3 can be made thinner. Hereby, breakdown of the insulating layer is reduced, and hence the yield of the manufacture and the device characteristics can be improved.
