Title: Snubber energy regeneration type partial resonance circuit
Inventor: TSURUTA YUKINORI
IPC: H02M1/06
Filed: 1993-10-29
Abstract: PURPOSE:To reduce the turn off loss of a main switching element by reducing the turn off loss of a self-arc-extinguishing element with a partial resonance circuit. CONSTITUTION:When a GTO 1U is turned on, a snubber capacitor(SC) 4U is charged. Moreover, when an auxiliary switch(AS) 6U is turned on, the charge of SC4U is discharged by the course of AS6U, a reactor(LA) 5U, and SC4U. And, when the charge of SC4U shifts to LA5U, it returns by the course of AS6U, LA5U, a diode(DD) 2U, and DD3U. When AS6U is turned off, the snubber energy accumulated in LA5U is regenerated on power source side by the course of DD7X, LA5U, and DD2U. This way, the turn off loss of GTO1U and 1X can be reduced by reducing the current of GTO1U and 1X at turn off. Moreover, the snubber load can be reduced by regenerating the surplus amount left last of the snubber energy made use for the reduction of turn off loss, in the main circuit.

Title: Device for notifying steel tower struck by lightning
Inventor: NOMICHI KENICHI
IPC: H02H3/16
Filed: 1994-11-07
Abstract: PURPOSE: To easily specify a steel tower struck by lightning even at night or in bad weather by providing a sensor, etc., which detects the magnetic flux caused by an electric current flowing through the steel tower. CONSTITUTION: A device for notifying steel tower struck by lightning is fitted to each steel tower for transmission line and when one steel tower is struck by lightning, the device fitted to the tower radiates radio waves. In other words, when an impact current flows through the tower due to lightning, a magnetic flux is generated from the leg of the tower and the flux is detected by means of a sensor coil 11. An overvoltage protective circuit 12 controls a photocoupler 13 by dividing the voltage and current so that the output of the coil 11 does not become higher than a fixed voltage. The photocoupler 13 gives a control signal to a timer 15 which turns on a system by means of a battery 14 through photocoupling. As a result, a control section 16 is actuated and gives the data of its own station to a transmitting section 17.  Another overvoltage protective circuit 18 connects the section 17 to an antenna 19. Therefore, the transmitted output is radiated as radio waves through the antenna 19. When a fixed period of time has elapsed, the timer 15 operates and sets the system to a turned-off state and all functions return to their initial standby states.

Title: End part chamfering method for plated mechanical part
Inventor: TAKAHASHI NAOHISA
IPC: C25D7/00
Filed: 1989-10-19
Abstract: PURPOSE:To reduce unevenness of a film thickness with current density changed continuously and generation of turbulence eliminated in plating fluid by chamfering an end part between an internal part and a through hole with high density energy irradiated before a plating layer is formed in the internal part having the through hole. CONSTITUTION:An end part 4 in a cylinder 1 is chamfered by irradiating it with high density energy of laser or the like and formed into a shape having curvature R. Thereafter by performing a plating process, a plating layer 3 of shape, having the curvature R in the end part 4, is formed. Since a port internal surface is prevented from being much plated as compared with a case not chamfered, this layer 3 is also prevented from being followed by deteriora tion of suction-exhaust efficiency. Accordingly, unevenness of a plated film thickness can be reduced, while in the case of using the cylinder 1 in which Si is deposited by an Al-Si alloy in the base material, since an insulator of Si is changed into a fine state by partly melting a surface of the cylinder by laser irradiation with conductivity of an Al part deteriorated, current density in the vicinity of the end part 4 is uniformly obtained further with unevenness of the plating film thickness enabled to reduce.

Since the light beam is turnably moved in such a constitution, the ROM 34 is provided in order to erase tracking offset which occurs in the case of the light beam's moving. Light spot position correction information previously stored in the ROM 34 is read out and the tracking offset is erased based on the read-out value.

Reflected luminous flux is led to the polarizing beam splitter 3, and the reflected luminous flux is separated to 0-order light and ±1st-order light by a diffraction grating 6. Respective separated luminous flux are separated to P/S polarization components by a wavelength plate 7 and a Wollaston prism 8, and are photoelectric converted/differential amplified respectively by a photodetector 10, and the reflected luminous flux from the land is separated from the reflected luminous flux from the groove.  The absolute value of the difference between the phase compensation amounts required for reproducing the signals from the land and groove is made 60 deg. to 180 deg..
