Inventor: JIKUMARU SHIYUUICHI
IPC: B66C13/46
Filed: 1988-12-09
Abstract: PURPOSE:To detect the quantity of the position shift between a conveyance indication coil and the coil hoisting accessory with high accuracy by providing two windows in the width and radial directions of a coil to be detected in a two-dimensional image from the coil and detecting the center coordinates from data only in the windows. CONSTITUTION:The outer peripheral surface of the coil is irradiated with light from a projector fitted to the coil hoisting accessory and a beltlike reflected image from the coil which extends in the axial direction is detected as the two-dimensional image. The windows in minimum necessary ranges in the width direction and radial direction of the coil are provided in the two-dimensional image and the center coordinates are found from the data only in the windows. Consequently, the number of arithmetic data is decreased without decreasing the detection resolution. Further, a threshold value is calculated from the mean brightness level of extracted linear data and made to correspond to variation in the reflection factor of the coil surface, and a value measured by an ultrasonic range finder fitted to the hoisting accessory is used as the height to the coil to improve the position shift detection accuracy.

Abstract: PROBLEM TO BE SOLVED: To improve the operability and the security protection of information by providing switching elements which select to connect first and second pixel regions through a capacitor or to short circuit the regions and switching the visual field angles in accordance with the utilization conditions and objectives. SOLUTION: When a switching element 15 is opened, pixel regions 12 and 13 are connected through a capacitor 14 and therefore, the driving voltages applied on a control line 16 are mutually different in the regions 12 and 13. Thus, the reversal of the gradation characteristic of pixels 11 is prevented and a wide visual field angle for a display screen is obtained and an image is displayed. If the elements 15 is short circuited, the regions 12 and 13 are directly connected and same driving voltages, which are applied to the line 16, are supplied to the regions 12 and 13. Therefore, the gradation characteristic of the pixels 11 is reversed depending on the viewing angle of an operator and a narrow visual field angle of the display screen is obtained and a picture is displayed accordingly.

Title: Operating mechanism of breaker
Inventor: HIDAKA MIKIO
IPC: H01H33/42
Filed: 1987-12-11
Abstract: PURPOSE:To eliminate a pulsation of a load and to make it possible to drive the breaker with a small capacity of driving source by making it possible to reengage a small gear and a large gear smoothly. CONSTITUTION:When a participant spring 7 accumulates the force, a large gear 8 is rotated by a small gear 9 and the force is accumulated by the large gear 8. As a result, no pulsation is generated to the load to a driving source of the small gear 9, and the driving source is rotated smoothly. After the participant spring 7 completes the force accumulation, the small gear 9 is engaged with the first tooth of a synchronous pawl 14 composed at the tooth lacking part 8a of the large gear 8, the rotation of the small gear 9 owing to the inertia of the driving source is escaped by a swaying of the synchronous pawl 14, and a large restricting torque of the driving source is not imposed to the large and the small gears 8 and 9. And in a closed circuit operation, since the second tooth of the synchronous pawl 14 is geared with the small gear 9 after the completion of the force accumulation, regardless of the swaying position of the synchronous pawl 14 geared with the small gear 9, the large gear 8 is engaged with the small gear 9 smoothly, and no excessive shock load is imposed to the gear surfaces. In such a way, no load pulsation is generated, and the unit can be driven by a small capacity of driving source.

Filed: 1993-12-13
Abstract: PURPOSE:To obtain an inexpensive dynamometer for a three-phase alternating current induction motor which is utilizable as an electric dynamometer, by setting the three-phase alternating current induction motor at a torque-measuring stage. CONSTITUTION:A three-phase alternating current induction motor 10 is set immediately above the center of a measuring stage 12. The measuring stage 12 has a yaw shaft 14 parallel to an axis O1-O2 of a main shaft 13. When a motor directly coupled to the main shaft 13 is driven, a loss power is generated. The loss power can be measured by driving the electric motor 10 with an optional rotating frequency via an inverter 25. Meanwhile, when the motor is driven, the electric motor 10 absorbs an output of the motor as regarding the motor in a minus slip state and feeds back the generated power to a power line 26. When the output of the motor is absorbed, a torque as a counterforce to a control force acts to the electric motor 10 supported on the stage 12 to be able to sway freely. The torque is detected by a load sensor 22a, so that the output power of the motor is measured.

Filed: 1989-11-30
Abstract: PURPOSE:To obtain a print having accurate gradation and an accurate color with respect to input data by adjusting one unit of the gradation corresponding to one unit of input data as the predetermined distance in a uniform sensation color space. CONSTITUTION:In an adjusting part, at first, an object 10 is irradiated with light from a light source 11 and the reflected light thereof is incident on an imaging tube 12 through a lens 13 and the spectrum of the incident light is detected. Subsequently, the tristimulus values (color matching functions) of the detected spectrum in an RGB color system are calculated and subsequently converted to the XYZ color system of CIE(Commission International de l' Eclairage). When the tristimulus values X, Y, Z of the color of the object are obtained, these values are converted to uniform sensation color space coordinates. Herein, the uniform sensation color space (USC space) means a space such that the distance between points showing two arbitrary colors shows the measured values of the color difference between those colors. Next, objective energy is calculated from input energy wherein evaluation functions DELTAE*, DELTAC* are printed and current supply quantity is set from the objective energy and this set value is outputted to an image data/current supply quantity table.

Title: Servo motor control system
Inventor: IWASHITA HEISUKE
IPC: G05B19/404
Filed: 1990-11-20
Abstract: PURPOSE:To improve the servo rigidity while working and to reduce the overshoot of a servo motor when it is stopped by making the integration of a speed loop integrator incomplete only at the time of stopping the servo motor. CONSTITUTION:A numerical controller (NC) 20 writes moving commands in a shared RAM 21 at every IPT period (distribution period) and the processor CPU of a digital servo circuit 22 read the movement commands from the RAM 21 and performs a position and speed loop processes at time intervals produced by dividing the IPT period. When a servo motor is normally operated, a speed loop integrator (for integration process) performs perfect integration. When the motor is stopped, on the other hand, the integrator is switched to incomplete integration from the distribution period one period prior tothe distribution period in which the moving command becomes '0' so that the integrated value can become smaller when the moving command becomes '0'. Therefore, when the servo motor is stopped, the servo rigidity can be obtained and, at the same time, the overshoot of the motor can be reduced.
