Title: Rotary torque detector
Inventor: OHARA TAMOTSU
IPC: G01L3/10
Filed: 1985-04-30
Abstract: PURPOSE:To obtain a stable, high-precision device whose measurement range can be varied from outside by providing plural opposite electrode surfaces which projects radially from a driving-side rotating shaft and a driven-side rotating shaft respectively. CONSTITUTION:The rotation of the driving shaft 1 is transmitted to the driven shaft 2 through the intervention of the lock force of a torque detection pin 12. At this time, if the driven shaft 2 is loaded, the load causes the pin 12 to flex, so an electrode interval varies and variable capacitors 27 and 28, therefore, vary in capacity. The electrostatic capacity variation of those capacitors 27 and 28 corresponding to torque variation is led out of the device with noncontacting structure through the coupling among capacitors 17, 18, and 19 by a fixed cylindrical electrode and a rotary cylindrical electrode and the quantity of the electric variation is processed to measure and display the torque value. Further, a stepping motor 16 is driven to move up and down a slide sleeve 13 and the length of projection of the pin 12 from a hole 1a is adjusted to adjust the measurement range of the torque value.

Title: Construction of temporary drain ditch on road surface
Inventor: MIZUNO YOUICHI
IPC: E02F5/10
Filed: 1982-05-31
Abstract: PURPOSE:To simplify the formation of a drain ditch by a method in which a temporary drain ditch is excavated on the shoulder of a road by pulling a framework having an excavating blade of a shape similar to the inside shape of the ditch by a power shovel, concrete is placed in the ditch, and a hopper serving as the framework in the inside of the ditch is pulled. CONSTITUTION:When constructing a temporary drain ditch on the surface of road, an excavating blade is projectionally provided to the lower part of a U-shaped framework and while the excavator is pulled in by the bucket of a back hoe 2, etc., a ditch 4 with a shape similar to the outside shape of the excavating blade is formed. Then, a concrete hopper 5 with same shape as the ditch is fixed to the square framework for placing concrete into the ditch, and while concrete 7 is discharged, the framework 5 of a ditch form is pulled by a rope and the concrete is placed on the inner surface of the ditch.

Title: Electrolytic inprocess dressing grinding wheel, electrolytic inprocess dressing grinding method and electrolytic inprocess dressing grinder
Inventor: TANI YASUHIRO
IPC: B24D11/00
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To grind a mirror surface to be high in quality and shorten an initial electrolytic dressing time so as to shorten a grinding time by using a grinding wheel composed of a binder, on whose surface a passive film made of a uniform and fine porous layer is produced. SOLUTION: When sharpening of a grinding wheel 11 is performed, electric resistance between the grinding wheel 11 and an electrode 14 is small and a relatively large current is supplied from a power source 16. By further continuing current application, a passive film composed of a porous layer 21 having a number of uniform and fine poroses 22 is formed via a barrier layer and electric resistance is increased. Thus, a current is reduced, melting-out of a metal part is reduced and jumping-out of ground particles is practically finished. When grinding is started in this condition, ground particles are worn with the grinding of a workpiece 13 while a grinding layer is gradually separated from the passive film, the passive film is eliminated and jumping-out of ground particles is resumed. Thus, by the formation and the elimination of the passive film, sharpening is automatically adjusted.

Title: Inspection for air leak of wrist watch
Inventor: YAMAGATA EICHIYOUSEI
IPC: G04D7/00
Filed: 1980-07-11
Abstract: PURPOSE:To enable to perform an accurate inspection to find whether a water proof is good or bad, by a method wherein the occurrence of air leak can be decided even if a distortion amount of a glass or a reverse lid diminishes while the inside of a capsul is increased in an air pressurization. CONSTITUTION:An output C of a comparator 14 is a >b as shown in a drawing while a distortion signal voltage (a) increases, and thereby it is a high level ''H''. Meanwhile, it is a <b when the distortion signal voltage (a) is 1% or more lower than a peak value, and thereby it is designed to be brought into a low level ''L'' through the inversion of the output (c) of the comparision 14. Even if the distortion signal voltage (a) changes as shown in a solid line, a voltage (b) changes as shown in a dashe line, and the output of the comparator 14 is once brought into ''L'' from ''H'' and brought into ''H'' again for the duration of an air pressure increasing time T1. Thus, even in this case, it is decided that an air exists when the output (c) of the comparator 14 inverts to ''L'' from ''H''. As a result, when an air pressure becomes in a constant state, the air leak can be detected even if a distortion amount does not change, and this permits the improvement of a water proof test.

Abstract: PURPOSE: To reduce an output error current even when a one-terminal type LPF is used by canceling the unbalance of a current Miller circuit part equivalently by switching an input to and an output from the circuit part.
