Title: Optical shaft torsion meter
Inventor: IKEDA TSUTOMU
IPC: G01B11/16
Filed: 1987-05-06
Abstract: PURPOSE:To eliminate the need for testing operation after the fitting and adjustment of a shaft torsion meter and to measure shaft torque speedily and securely by fitting a couple of front and rear fixed rings on the outer peripheral surface of a rotary shaft at a proper shaft distance. CONSTITUTION:A main body 4 and a reflecting mirror are fitted on a fixed ring and when a light source (a) is tuned on, two parallel light beams are obtained through the slits of a slit plate (b). Those parallel slit light beams are reflected by the reflecting mirror, enlarged by a magnifying lens 18, and projected on a photodetection sensor C, so that the addresses (n) of an element at light points S2 and S1 of the slits are detected respectively as shown in a figure. In this state, when the shaft is rotated to place a load, the light spot S2 of the slit on the sensor C moves to S2' and the light spot S1 moves to above S2' to scale out; and the current output voltage Vm is obtained as a measured value, so the current torsion delta of the shaft is found from an equation.

Title: Variable speed hoist
Inventor: NAKAMURA YOJI
IPC: B66D1/46
Filed: 1989-04-28
Abstract: PURPOSE:To obtain a variable speed hoist which is low-priced and has good working efficiency by switching the frequency of a hoisting motor to the frequency higher than the reference frequency when the rotating speed of the hoisting motor at the time of performing a hoisting operation at the reference frequency exceeds the preset reference speed. CONSTITUTION:At the time of performing a hoisting operation at the reference frequency, if load is light and near no-load and the rate of load to rated load is small, the rotating speed of a hoisting motor 2 exceeds the preset reference speed, so that a frequency designation selecting device 10 closes an always open contact 10a and opens an always close contact 10b at the time the preset time elapses. Whereupon, an inverter 1 short-circuits a high-frequency 120Hz select input terminal H and a common terminal G to select high frequency, and starts increasing the frequency to 120Hz with a preset gradient to increase the speed of the hoisting motor 2. When the frequency reaches 120Hz, the inverter 1 stops increasing of the frequency, and the hoisting motor 2 is operated with constant speed rotation at high speed.

Filed: 1983-06-21
Abstract: PURPOSE:To stop an original at a correct exposure position by finding the extent of movement of an original feed belt accurately from the extent of rotation of a belt driving motor, and matching it with the length of the original. CONSTITUTION:When a printing start switch is depressed, stoppers 47 and 34 are displaced downward and the original feed belt 30 and a conveyance roller 35 operate; the former sends out an original which is possibly left on exposure glass 2 to a paper discharging part 51, and the latter sends a new original O to a resist roller 36.

Filed: 1977-09-19
Abstract: PURPOSE: To improve the reliability in lap joining of the inside of one pipe with that of another by ultrasoldering, by preventing the shrinkage cavity tending to promote corrosion through proper handling of solidification after soldering.  
     CONSTITUTION: One end of an inner tube made of copper material or the like is inserted into an outer tube made of aluminium material or the like up to a given depth and then, an ultrasonic soldering is performed. In the process of pulling the soldered joint from a solder bath, the pulling is halted temporarily before the open end 11a of the outer tube is completely separated from the surface of the solder bath. After the solder half melted at the pulled section is allowed to solidify, the joint is pulled again and then, cooled. Accordingly, the open end 11a is fed with solder sufficient to cover the shrinkage accompanying the solidification from the bath thereby checking the generation of shrinkage cavity.

Abstract: PURPOSE:To obtain high brightness by setting up a delay time in the timing of video signals to be impressed to two electron gans for a blue projection tube and applying the video signal to the 2nd gan with an optimum delay time from the video signal applied to the 1st gan. CONSTITUTION:In the projection type television device using three, red, green and blue, projection tubes 7 to 9, the blue projection tube 9 has two electron gans.
