Title: Elevation controlling method of welding electrode and apparatus thereof
Inventor: HASEGAWA KAZUYOSHI
IPC: B23K9/12
Filed: 1979-02-23
Abstract: PURPOSE: To prevent the production of gouges of the work and the damages of electrode by gradually decreasing the exhaust pressure for lowering the welding electrode through the use of a diaphragm valve thereby gently lowering the welding electrode.  
     CONSTITUTION: To perform spot welding with the welding electrode 1 being held locked in the up position, two-way electromagnetic change-over valves 11, 14 are energized to change-over the valve 11 on the pressure side to the position where the diaphragm valve 3 side pipe line and air pressure source 7 side pipe line communicate. Further, the valve 14 on the up side is changed over to the cut-off position of a low pressure reducing valve 13 and quick exhaust valve 15. Next, the valve 8 is opened to allow the air pressure of the air pressure source 7 to flow into the diaphragm upper chamber 4a through filter 9 and valve 11. Since the upper chamber 4a is gradually boosted and the quick exhaust valve 15 acts as a relief valve, the lower chamber 4b is gradually reduced of pressure, causing the electrode 1 to descend gently and press the work not illustrated. According to this method, the forging pressure rising speed can be increased, hence the results of welding such as Al alloy may be enhanced.

Title: Blast furnace operating method
Inventor: YAGI MITSUO
IPC: C21B5/00
Filed: 1979-02-27
Abstract: PURPOSE:To improve the circumference balance collapsion of the fusion bonded zone and eliminate gas deviation flow by grasping the timings at which the differences in the furnace top gas density of the same radius level by each direction and shaft pressure values occur at the blast furnace operation and performing reducing blowing down operation to lower the raw descending material level then doing such things as operation controlling. CONSTITUTION:At the blast furnace operation, the timings at which the differences in the furnace top gas density of the same radius level by each direction and shaft pressure values occur are grasped. Thence, the reducing blowing down operation is done to lower the raw descending material level down to the shaft lower part, barrel or bosh part below the existing fusion-bonded zone level, so that the fusion-bonded zone is rebuilt. Namely, by lowering the descending raw materials down to the shaft lower part or bosh below the existing fusion-bonded zone level, the fusion-bonded zone volume after the reduction becomes 50% or less of the existing fusion-bonded zone volume. According to this method, the in-furnace gas reduction efficiency improves and the Si variations in iron and fuel ratio may be lowered.

Abstract: PROBLEM TO BE SOLVED: To reduce the number of electric discharging electrodes necessary for die manufacturing as many as possible and to increase the machining accuracy of a notched surface for each die. SOLUTION: The manufacture of a die for a helical gear comprises the steps of entering an electric discharge electrode 1 into the hole 10 of a die material 9 while rotating the same, forming helical projected and recessed parts 16 and 15 in the inner peripheral surface of the die material 9 by machining the die material 9 by electric discharging, and then taking the electric discharge electrode 1 out of the die material 9 while rotating the same in an opposite direction.  In this case, for taking the electric discharge electrode 1 out of the die material 9, the rate of a rotating amount corresponding to the moving amount of an axial direction after the electric discharge electrode 1 reaches a specified position in the hole 10 of the die material 9 is reduced more than that of a rotating amount corresponding to the moving amount of an axial direction before the electric discharge electrode 1 reaches the specified position in the hole 10 of the same, and a notched surface 17 is formed by eliminating a part of the projected part 16 formed in the hole of the die material 9 by electric discharge machining.

Abstract: PURPOSE:To prevent deviation in the indication between an indicator and an alarm needle, by driving a wheel train faster than the normal speed with a switch input to a drive control circuit from a mode switch to halt the output from a drive circuit when electric connection between two contact members is detected. CONSTITUTION:A drive circuit 3 enters a contact detection mode of a contact switch 18 by a short-circuit signal of a mode switch 20 and the output pulse to the drive circuit 4 is altered to 128Hz from 1Hz in the normal point until the turning ON of the contact switch from a detection circuit 19 is detected to drive the wheel train 6 at a high speed. When the mode switch 20 fails to short-circuit to VDD while the detection signal of the detection circuit 19 is inputted, an alarm control circuit 9 outputs a clock pulse to an alarm driving circuit 10 for 20sec and the mode switch 20 enters the wheel train detection mode, short-circuiting to the VDD to output a clock pulse to the alarm drive circuit 10 when a contact conduction signal of the detection circuit 19 is inputted. This enable easy self-detection of indication deviation of a pointer and also facilitate the calculation of a drive pulse necessary for the correction of the indication deviation of the pointer thereby enabling self correction.

Title: Ceramic heater and oxygen sensor using the same
Inventor: TANAKA SATOSHI
IPC: G01N27/409
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To reduce the amount of Na segregating to a lead take-out part at the cathode side and prevent oxidation of Pt, by reducing a content of Na in an insulating ceramic in which a heating resistor essentially consisting of Pt is buried to a specific amount or smaller. SOLUTION: A heating resistor 3 consisting essentially of Pt is buried in a plate-shaped insulating ceramic body 2. End parts of the heating resistor 3 exposed to an end face of the insulating ceramic body 2 form lead terminals 4a and 4b at the anode side and cathode side of a ceramic heater 1. At this time, the content of Na included in the insulating ceramic body 2 is reduced to approximately 50 ppm or lower. Accordingly, an amount of Na ions segregating to the lead take-out part 4b at the cathode side is reduced, whereby Pt is prevented from being oxidized. Even when repeatedly heated, the heating resistor can heat to a prescribed temperature at all times.

Abstract: PURPOSE:To cancel the deviation of ions and the accumulation of charges and to lessen hysteresis and unstability by providing the surfaces of oriented films with metallic films connected to electrodes. CONSTITUTION:The films of a conductive indium tin oxide are formed by sputtering on glass substrates 11 to form transparent electrodes 12.

The deviation of the ions and the accumulation of the charges which are the problems in FLC(ferroelectric liquid crystal) intermediate display are thereby canceled. Consequently, the hysteresis and unstability are drastically lessened and the flat display is attained with high-speed responsiveness and high fineness.

Filed: 1980-02-28
Abstract: PURPOSE:To make it possible to guide a flying object to many targets without lowering the probability of collision to the targets, by correcting the course of the  flying body to its further estimated point upon occasion. CONSTITUTION:Guidance device 10 consists of target position tracking device 4, estimating device 5 for the future position of a target, discriminator 11 for the necessity of correction, and correction signal transmitter 12. Once tracking device 4 outputs the position of the target, estimating device 5, on the basis of this data, outputs position 13 of the collision between flying body 2 and the target or estimated position 15 for the observation of the necessity of the course correction of flying object 2 and the estimated time that corresponds to each estimated position. Next, tracking device 4 tracks the target after the estimated time when the target reaches position 15 to compare the obtained target position with the estimated position of position 15, and discriminator 11 makes a judgement according to the difference, so that transmitter 12 will send a course correction signal to flying object 2. Thus, the flying object can be guided to many targets without lowering the probability of collision.
