Title: Cable drum assembling apparatus
Inventor: SUZUKI YOSHIAKI
IPC: B65H75/14
Filed: 1985-08-31
Abstract: PURPOSE:To efficiently manufacture a cable drum having the superior balance by setting the pressing plates having a fitting groove for the fitting between a rib and the right and left collar plates of a machine frame so as to be set oppositely each other and to be brought close to each other and installing an annular holder which can be divided between the both pressing plates and nipping a taking-up drum. CONSTITUTION:The rib of the collar plate 9 of a cable drum is fitted into the fitting grooves 10 of the right and left pressing plates 5 and 6 of a machine frame 1, and an annular holder 21 is divided, and a taking-up drum 41 is interposed therebetween. Then, one pressing plate is bought close to the other pressing plate, and when the collar plate 9 contacts the both edges of the taking-up drum 41, the annular holder 21 is returned into annular form, and the taking-up drum 41 is shaped into cylindrical form and nipped. When, in this state, the annular holder 21 is separated and the pressing plates are revolved, the collar plate 9 and the taking-up drum 41 revolve integrally. Therefore, a cable drum can be assembled by welding the joint part between the collar plate 9 and the taking-up drum 41. Therefore, the axis lines of the right and left collar plates and of the taking-up drum coincide, and the taking-up drum can be formed into cylindrical form.

Inventor: MURAKAWA KAZUO
IPC: G01R27/20
Filed: 1998-07-07
Abstract: PROBLEM TO BE SOLVED: To provide a grounding resistance measurement method and device for eliminating the need for measuring a complex amount. SOLUTION: The measurement signal of a frequency, that matches the series resonance frequency of a ground return circuit that is composed of a grounding electrode 11, a metal plate 12, an insulation member 13, and lead wires 14A and 14B, is supplied from a measuring instrument 20. By causing the imaginary part of the impedance of the ground return circuit to be set to zero and utilizing that a complex amount is not related to the measurement of a reflection power, measurement can be made at a real number region, obtaining the absolute value of a reflection coefficient from reflected and incident powers, and the grounding resistance of the grounding electrode 11 is measured. As a result, the need for measurement at a complex region, as in a conventional case, is eliminated, the configuration of a measuring device is simplified, and furthermore a consumption power can be reduced.

IPC: H03C1/02
Filed: 1981-11-30
Abstract: PURPOSE:To keep a prescribed modulation degree to the change of load, by detecting the carrier signal level and the low frequency signal level from the modulated wave signal of output and applying feedback after comparing both levels with each other. CONSTITUTION:The carrier signal supplied from an oscillator (not shown in figure) is fed to a modulation amplifying circuit 8 after high frequency amplification 7. While the low frequency signal is fed to the circuit 8 after low frequency amplification 10. The carrier signal is modulated with the low frequency signal through the circuit 8 and amplified again to be delivered in the form of the modulated wave signal. This modulated wave signal is fed to an extracting circuit 11 for carrier signal component and to an extracting circuit 12 for low frequency signal component. Thus the carrier signal component obtained with no modulation given by the low frequency signal is extracted out of the circuit 11, and the rectified 13 carrier signal level A is fed to a voltage comparator 15. At the same time, the low-frequency signal component is extracted out of the circuit 12, and the low frequency signal level B is fed to the circuit 15. The circuit 12 performs the relative voltage comparison between the signal levels A and B and then applies feedback.

Abstract: PURPOSE:To suppress the temperature rise of the thin film magnetic head and to generate a large magnetic field at the time of writing by making the area of an upper magnetic pole large enough to cover the both ends and the rear end of a conductor coil. CONSTITUTION:An upper magnetic pole 11 is equipped with a main body part 11a for covering the front part of a conductor coil 3 and a cover part 11b for covering the both ends and the rear end of the conductor coil 3 by extending at the back of this main body part 11a and extending to right and left, and this cover part 11b is attached onto a substrate 1 while protruding the both ends from the both ends of the conductor coil 3. The Joule heat of the conductor coil 3 is propagated to the upper magnetic pole 11 and radiated through a protecting layer 5 and the substrate 1, etc. In such a case, since the upper magnetic pole 11 covers the surface of the conductor coil 3, the heat is speedily radiated to the outside. Thus, when a large current flows to the conductor coil 3 to generate a strong magnetic field, the temperature rise is suppressed, thermal noise generated from the conductor coil 3 is reduced, and the thin film magnetic head with a high resonance frequency can be obtained.
