Title: Insulation resistance testing method for winding core
Inventor: TAKADA YOSHIAKI
IPC: G11B5/455
Filed: 1986-06-27
Abstract: PURPOSE:To prevent an accident due to an insulation resistance from being generated, by measuring an insulation resistance value between one of two pieces of cores, and one of two pieces of cores on a winding end part side, and deciding the quality of the insulation resistance by comparing the insulating resistance value, and a threshold value to secure the insulation resistance. CONSTITUTION:At the time of measuring an insulation resistance value R between a winding 1, and a C core 2, firstly, a resistance value R1 between two arbitrary points 2a, 2a of the C core 2 on which the winding 1 is applied, is measured, and next, a resistance value R2 between two points 1a, 1a on the free terminal side of the winding, is measured. When each of the resistance values R1 and R2 is below each of the threshold values set respectively, it means that the contact between the electrode of a measuring instrument, and a work 3 and the winding 1, is in a good state. Next, the resistance value R of one point between 1a and 2a, out of two points, is measured, respectively. The insulation resistance value obtained in such a way, is increased higher than the threshold value by imperfect contact between the electrode, and work 3 or the winding 1, therefore, it is possible to prevent the quality of the insulation resistance to be decided erroneously, and the accident to lower an electromagnetic conversion function, or to damage a device from generating.

IPC: G01N21/78
Filed: 1987-06-16
Abstract: PURPOSE:To prevent the cracking of the surface of a film wound on a roll by specifying the diameter of the roll wound with an analyzing tape to >=30mm. CONSTITUTION:The analyzing tape 2 supplied from the roll 2a (the diameter of which is specified to >=30mm) in a cassette 3 is sent from a cold retaining chamber 4 out through a window provided with as shutter 8 to a measuring section. Low-humidity air is supplied atop the tape 2 en route thereof by a blasting means 5. The rear face of the tape 2 is preheated to a suitable temp. near room temp. by a preheater 7. An optical measurement probe 12 projects a luminous flux for measurement to the rear face of the tape 2 and receives the light reflected therefrom. The reflection optical density of the irradiated surface is measured by measuring the quantity of the reflected light. The tape 2 is transiently stopped by a heat retaining block 11 and is spotted 9 with a sample, following which the tape is kept at a desired temp. for a suitable period and thereafter, the reflection optical density is measured with the probe 12 and a photometric means 16. The cracking on the surface of the film wound on the roll 2a is thus obviated.

Title: Method and device for measuring shape of cylindrical cam
Inventor: USHIKUSA MORIHITO
IPC: B23Q17/20
Filed: 1991-05-24
Abstract: PURPOSE:To cause coincidence of a cam with a regular measurement starting point through correction of an error by calculating an error angle with the measurement starting point of the cam mounted on a reference point planned during measurement of the shape of a manufactured cam. CONSTITUTION:A cam P is supported to a support bed 4 capable of controlling revolution dividing, an error detector 37 is located to a slider capable of controlling positioning in the direction of an R-axis, and a manual cam P is mounted so that a temporary measurement starting point R1 is set to a value within + or -10 deg. of a design reference point (a regular measurement starting point) R0. Based on the temporary measurement stating point R1, measurement is determined through temporary measurement and a difference eni between a change amount  r'n of a cam profile radium and a change amount  r''ni of a design value of thetai calculated by a design formula is determined. An angle thetai at which a square sum of the difference eni is minimized is determined. By correcting and rotating the temporary measurement starting position of a cam based on the thetai forming an angle displacement amount T, the cam is caused to coincide with the regular measurement starting point.

Title: Synchronizing control system
Inventor: SASAKI TAKAO
IPC: G05B19/4103
Filed: 1990-06-07
Abstract: PURPOSE:To improve the machining accuracy of gears and screws by providing a virtual distribution means to an axis control circuit and performing the synchronizing control with output of a synchronizing pulse. CONSTITUTION:An axis control circuit 20 contains a virtual distribution circuit 24 which distributes virtually the feedback pulses sent from a pulse coder 7 connected to a spindle motor 4. The means 24 also distributes virtually the feedback pulses sent from a pulse coder 5 and drives a servo motor 6. In order words, an output pulse of the coder 5 is multiplied by a fixed coefficient K. As a result, the circuit 20 performs its processing at a speed higher than an interpolation period of a numerical controller 10. Furthermore no delay is produced to the transfer time of the controller 10 to the circuit 20. Thus the processing speed is increased and the step-out level is reduced. Then the machining accuracy is improved for the gear cutting and screw cutting.

Abstract: PURPOSE: To improve electric connecting ability between a feed terminal on the fusion controller side and an electrode metal fitting on the coupling body side by mounting a protrusion belt-form belt on one of joints brought into electric contact with an electrode metal fitting and a feed terminal. CONSTITUTION: An electrode metal fitting 13 of an electric fusion coupling 10 is provided with a pressure terminal 14 to connect heating wire 12. Further, the electrode metal fitting 13 has a protrusion belt-form belt 15 embedded in a stepped inside diameter part 13A. A protrusion belt-like belt 15 is rounded in a C-shape, a strip-form crest is formed at a central part, and a spring contact part is formed. When the protrusion belt-form belt 15 is inserted in the stepped inside diameter part 13A of an electrode metal fitting 13, as a result of the peripheral direction of C being forcibly contracted for insertion, this is spread by a reaction force and the belt fits the stepped inside diameter part 13A of the electrode metal fitting 13.  When a feed terminal is fitted in the electrode metal fitting 13, reliable contact at a strip-form contact part is effected and besides the electrode metal fitting provides resistance for prevention of coming- off of the feed terminal during energization.
