Title: Constant speed control circuit of motor
Inventor: IKEDA IKUMASA
IPC: H02P7/03
Filed: 1987-03-05
Abstract: PURPOSE:To enable a motor to reach a constant speed state in changing its speed and in reversing its direction within the shortest time, by changing the time constant or amplification degree of a smoothing circuit both in the reverse rotation and in the constant speed rotation of the motor. CONSTITUTION:When the number of revolutions of a motor 1 is lower than the set number of revolutions due to a variable resistor 11 by a specified number of revolutions, an operational amplifier 21 becomes low-level while the output of an inverter 24 becomes high-level. An analogue switch 22 is thereby conducted while an analogue switch 23 is non-conducted. The amplification degree of an operational amplifier 13 is determined by resistances 14 and 15. When the speed of the motor 1 is increasing to approach the preset value, the output of the operational amplifier 21 gets high-level while the analogue switch 22 becomes non-conductive and the analogue switch 23 conductive. Under this circumstances, a negative feedback path by a resistance 16 and a capacitor 17 is formed.

Abstract: PURPOSE:To enable to select either of idle vibration preventing operation or creep operation, by providing a mechanism for preventing coupling of a clutch when the throttle valve of an engine is positioned at its idling opening, in the manner that the mechanism cannot be operated freely from the driver's position in the cabin of a vehicle. CONSTITUTION:A coupling preventing mechanism 16 is designed such that, when an output signal is produced from both an idle opening detector 23 attached to a throttle pedal 22 and a means 25 for detecting stoppage of vehicle which produces an output signal when the vehicle is operated at an extremely low speed, a switch 27 is closed and a solenoid 20 is connected to a battery 28. This causes opening of a valve 19, so that pressure oil is drawn to a drain passage 18 and therefore coupling of a first-speed clutch 9-1 is prevented. Further, a switch 38 is connected, in series to the switch 27, in a circuit for connecting the solenoid 20 to the battery 28. The switch 38 is associated with a control lever 10 and is opened for interrupting current supply to the solenoid 20 when it is shifted to an L-range.

Filed: 1986-03-07
Abstract: PURPOSE:To simplify the circuit constitution by providing a switch in a loop of a tracking control loop consisting of a track error signal detecting means, a tracking control means and an objective lens driving means. CONSTITUTION:When a tracking signal T.R. is within a range of 'H', a switch 17 is closed, a tracking control loop is closed and tracking control is executed. In a section of t0 t1, a tracking error signal T.E. is negative, therefore, a tracking actuator generates force in the negative direction, and also, in a section of t2 t3, the tracking error signal is positive, therefore, the force is generated in the positive direction Also, when an optical spot moves to a track A B' direction (negative direction), the force is generated in the positive direction in a section t0-t1', and in the negative direction of a section t2'-t3', and the time required for generating the force in the negative direction is shortened. In this way, by simple circuit constitution, correct brake control is applied, and stable tracking reading-in can be executed in a short time.

Filed: 1982-03-31
Abstract: PURPOSE:To improve insulating characteristics and to reduce short circuits and wire breakdown, by providing a silicon oxide film, which is obtained by internally oxidizing a silicon layer, between a high melting point metal layer and the silicon layer. CONSTITUTION:A substrate 1 is constituted by a single crystal silicon substrate 2 and an insulating film 3, e.g., a silicon oxide with a thickness of 400Angstrom . A high melting point metal layer 4 is formed on the substrate 1. It is necessary that the material having the following features is used for the metal layer 4: resistivity is low; heat resistance is high; and the oxide including said material can be readily reduced by the heat treatment in an atmosphere including hydrogen. Then the surface of the high melting point metal layer is oxidized, and a high melting point metal oxide layer 20 is formed. It is necessary to use MoO2, whose melting point is as high as 1,900 deg.C and which is stable at a high temperature for the oxide layer 20. For this purpose, e.g., Mo is oxidized in oxygen atmosphere at about 300 deg.C, and MoO3 is once formed on the surface of Mo. Then heat treatment is performed in an inactive gas at a temperature close to a sublimation point of MoO3 or higher, and MoO3 is transformed into MoO2. Thus MoO2 is formed on the surface of Mo by adopting this method.

Title: Method for measuring minute dimension
Inventor: FUJITA HIROO
IPC: G01B11/02
Filed: 1987-03-06
Abstract: PURPOSE:To obtain a dimension with high accuracy even when an object to be measured has varying surface reflectivity by taking correlation between two or more quantities from the intensity value at the point becoming the extreme value of a W-shaped pattern and a total intensity value and independently calculating the surface reflectivity and dimension of the object to be measured. CONSTITUTION:The intensity of a reflected beam from a base material part 22 becomes max. or the intensity of the reflected beam from a reference part 21 becomes min. based on whether the surface reflectivity of the dimension part 21 of an object 20 to be measured is lower or higher than that of the base material part 22 and an M- shaped intensity patterns is shown. Min. and max. intensity detection parts 10, 11 respectively detect the value mp of the min. intensity and the value cp of the max. intensity and a total intensity detection part 12 detects the sum total sp of the reflection intensities within a predetermined region. Herein, from the correlation between two arbitrary values among the values mp, cp and sp, not only the dimension of the dimension part 21 but also the variation in surface reflectivity can be detected and, from the curve of a reflected beam intensity pattern, it can be also judged whether the geometrical shape of the object 20 to be measured is normal or foreign matter such as dust is adhered to said object.
