IPC: B23K26/21
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To obtain a joint which does not heat the inner part of a vessel to a high temp. regarded as giving the adverse effect to the contents and has high closeness and does not develop a root crack by joining the vessel main body and a cover body in a specific range to the ratio of the depth of a fused joining part and the width of the fused joining part. SOLUTION: For example, a part of a vessel body composed of Al or an Al alloy is notched and a cover body 2 is fitted to join the vessel body 1 and the cover body 2. Then, the ratio of the depth D of a fused joining part 3 and the width W of the fused joining part 3, i.e., an aspect ratio (D/W) is made to 1-5. At the time of using a slab laser beam as a high density heat source, a condition, in which the aspect ratio at the joining part is made to >=1, is easily found by executing a simply test and the aluminum closed vessel usable as a case for a high density battery of a high performance lithium ion secondary battery, etc., excellent in impact resistance can be manufactured by executing a simple test run.

Title: Liquid crystal display device
Inventor: KIMURA YUICHIRO
IPC: G02F1/133
Filed: 1987-11-11
Abstract: PURPOSE:To decrease baking and flickering which are generated by a fluctuation in the voltages impressed to a liquid crystal cell by switching the voltages impressed to gate buses according to the polarities of the video signal impressed to the liquid crystal cell. CONSTITUTION:Both the on and off voltage of gates are switched to 2 ways respectively according to the polarities of the source voltage. Namely, an analog data selector 14 switches the polarities of the signal impressed to the liquid crystal cell switches 4 kinds of the external input voltages V1-V4 to suppress the falling width of the gate voltages which affect punch-through to a min required level. The gates of thin film transistors (FT) are driven to turn off the TFTs at the min required voltage according to the polarities of the video signal in such a manner and, therefore, the punch-through by the gate-source capacity CGS is decreased and the flickering and baking are suppressed as well.

Title: Radar device
Inventor: TSUKAGUCHI SATOKO
IPC: G01S13/87
Filed: 1988-11-09
Abstract: PURPOSE:To reduce the size of the device scale by using different frequencies for long distance and short distance, using a local oscillator in common, and changing a pulse compressive modulation system for a center frequency by a reception system. CONSTITUTION:A 1st frequency-modulated expanded pulse is obtained by imposing frequency modulation on a signal from a 1st sent signal generator 14a with a modulating signal from a 1st pulse compressive modulation generator 15a. A 2nd frequency-modulated expanded pulse, on the other hand, is obtained by imposing frequency modulation upon a signal from a 2nd sent signal generator 14b with a modulating signal from a 2nd frequency modulation generator 15b. Those 1st and 2nd frequency-modulated expanded pulses are put together by a 1st composition device 12a, frequency-converted by a 5th frequency modulator 11a by receiving a signal from the local oscillator 9, and amplified, so that the resulting signal is transmitted from an antenna 1a. If a sent signal from a 2nd antenna system 1b enters a 1st antenna system 1a, the signal is distributed by a 1st distributor 5a, but the modulating signals differ in center frequency, so the signal does not pass through 1st and 2nd compressing filters 6a and 6b, thereby evading misrecognition.

Title: High-voltage rotary electric machine coil
Inventor: HAGA KOJI
IPC: H02K3/32
Filed: 1988-11-09
Abstract: PURPOSE:To improve reliability of insulation by forming a reinforcing insulating layer composed of a thermosetting resin containing mica powder extending over specified length including the bent section of an aligned coil conductor and increasing the radius of curvature of the inside diameter side surface of the reinforcing insulating layer. CONSTITUTION:A reinforcing insulating layer 11 consisting of the cured layer of a thermosetting resin comprising mica powder within the range of specified length including the bent section of an aligned coil conductor 1 is shaped, and the thickness of the reinforcing insulating layer 11 is adjusted so that the radius of curvature of the inside diameter side of the layer 11 is made larger than that of the inside diameter side of the bent section 15 of the aligned coil conductor. Consequently, since the ratio of the radius of curvature R of the inside diameter side of the bent section of the reinforcing insulating layer 11 to the radius of curvature of the outside diameter side is lowered, the ununiformity of the taping thickness of a base material tape and defects such as winding thickness, the crease and clearance of the tape, etc., are reduced, thus forming the equal insulating base material layer 11. Accordingly, the difference of thermal stress-resistant characteristics and partial discharge characteristics and the like in the linear section and bent section of a main insulating layer 12 obtained through impregnation and curing is removed, thus improving reliability of insulation.

Title: Cover and upper structure of arc furnace
Inventor: MAGARINO TETSUJI
IPC: F27D1/18
Filed: 1994-10-26
Abstract: PURPOSE: To ensure a cover and an upper structure of an arc furnace which is capable of preventing scrap from being deposited, of preventing a furnace upper part from being thermally deformed, and of stable gas sealing by providing a furnace cover receptacle for placing the furnace cover on the furnace upper part outside the furnace upper part, and configuring the receptacle into a cone enlarging externally downwardly. CONSTITUTION: A furnace cover receptacle 5 is fixed outside an upper part of a furnace body, and the upper part of the furnace cover receptacle 5 is configured into a cone enlarging externally downwardly. During melting and rectification a furnace cover 2 is put on the upper surface of the furnace cover receptacle 5. Scrap is thrown in by opening the furnace cover 2. In this case, scrap scattered over a furnace outer periphery slips downward without being deposited on the upper surface of the furnace cover receptacle 5. This ensures stable gas sealing at a contact between the furnace upper part and the furnace cover, so that suction effect for waste gas produced in the furnace is increased and hence the working environment is improved. The initial cost and the running cost are reduced because the amount of sucked air can be reduced.

Abstract: PURPOSE:To suppress the fluctuation in reproducing power by detecting the fluctuational characteristic in the reproducing power at the time of switching on/off of superposition of high frequency current to the drive current of a semiconductor laser and correcting the drive current. CONSTITUTION:A high frequency current superposition module 22 is turned on by a control signal from a CPU 23, and the reproducing power from the semiconductor laser 11 is controlled by a reproducing power control part 21.

By the CPU 23, a time from when a module 22 is turned on to when the output signal of the comparator 29 becomes '1' is measured, and a current value with a characteristic opposite to the fluctuation characteristic of the reproducing power is set to an addition current generation part 30, and is added to the drive current of the laser 11 by an adder part 31. Thus, the fluctuation in the reproducing power is suppressed.
