Title: Nonconsumable electrode arc welding method
Inventor: OGINO TADAAKI
IPC: B23K9/127
Filed: 1986-04-22
Abstract: PURPOSE:To perform the smooth titled welding by superimposing an exciting signal with prescribed amplitude and frequency on a separated distance adjusting signal to control the arc voltage between materials to be welded and an electrode fixedly and adjusting and controlling the separated distance and making fine adjustment of the arc voltage. CONSTITUTION:The voltage of a torch 5 of TIG welding equipment to perform the continuous welding while filler material 3 is fed to an arc 5a between a rotating 11 steel pipe 4 and a welding torch 5 is compared with the prescribed voltage of an arc voltage setting device 7 with an adder 12 and a motor 11 is driven with a torch elevating device 2 and the arc voltage is maintained constant. There is a blind sector in the control signal voltage in that case and the smooth adjustment cannot be made. Then, when the exciting signal 10 with the amplitude of about l.l-l.2 times as much as the blind sector width and the frequency of about 5-10HZ is superimposed on the adder 12 from an oscillator 6, the adjusting signal is sent to the elevating device 2 and the torch 5 is moved up and down and the arc voltage is fine-adjusted fixedly almost regardless of the blind sector.

IPC: H05B3/00
Filed: 1986-04-23
Abstract: PURPOSE:To shorten an electric feed time and to improve heat efficiency by starting feeding electricity for heating before a heat roller and a pressure roller abut with each other across a toner image support body and holding the toner image support body at specific temperature, and stopping the electric feeding beyond a contact. CONSTITUTION:A paper detection sensor 11 supplied a signal indicating the entrance timing of the toner image support 100 to a controller 20 and then an electrode 10 is applied with a voltage; and the electric resistance heat generating zone 7 of the heat roller 1 is fed with electricity to generate heat, so that the surface temperature rises. The surface of the heat roller 1 which begins to rise in temperature after contacting the electrode 10 by the rotation of the heat roller 1 reaches temperature which is high enough for fixation when it reaches a nip part formed along with the pressure roller 2. When the tone image support body 100 passes the nip part, a toner image 102 is fused with heat supplied from the heat roller 1 and penetrates the support body 101 by being pressed by the pressure roller 2, so that the toner image 102 is fixed to the support body 101 by natural cooling after passing the nip part.

Title: Gas feeder with cylinder
Inventor: YOKOKI KAZUO
IPC: B08B9/02
Filed: 1990-04-11
Abstract: PURPOSE:To prevent a gas leakage from occurring by installing a purge line for purging gas and a safety line between a cylinder and a gas supply line, purging gas in the gas supply line at time of cylinder replacement, and exhausting the gas from a vent port. CONSTITUTION:Both high pressure and low pressure on-off valves 4a, 5a and 4b, 5b are installed in gas supply lines 3a, 3b, interconnecting an interval between each line and a vent port 9 with safety lines 16a, 16b, and two on-off valves 17a, 17b are installed there. For example, when a cylinder 1a is replaced, an on-off valve 8a in a purge line 7a and another on-off valve 11a in a vent line 10a both are closed and an on-off valve 17a in the safety line is opened instead after exhaust of gas in the supply line 3a has been performed by purging N2 gas. Thus, a vacuum by an ejector 12 is made to act on the supply line 3a, thereby exhausting the residual gas out of the vent port 9. Therefore even if there is a leak in the high-pressure on-off valve 4a, a gas leakage to the outside will not happen at all.

Title: Single phase induction motor
Inventor: SAKAI KAZUMA
IPC: H02P1/42
Filed: 1988-04-15
Abstract: PURPOSE:To increase the accelerating torque in starting a motor with the stalling torque in operation ensured by connecting a series circuit of a part of auxiliary windings and an operating capacitor in parallel to a positive temperature coefficient thermistor. CONSTITUTION:In starting a motor immediately after the power supply 2 is put to work when the temperature of a positive temperature coefficient thermistor 4 is low and the resistance value is small, the current flows to main windings M1 and M2, auxiliary windings A1 and A2 and the positive temperature coefficient thermistor 4, since the resistance of an operating capacitor is large, so that a motor starts by a phase-shifting method. After that, as positive temperature coefficient thermistor 4 is gradually self-heated and the resistance value increased, the thermistor 4 is interrupted from a circuit and the current flows to main windings M1 and M2, auxiliary windings A1, A2 and A3 and the operating capacitor 3. In this way, a single-phase induction motor of PTC capacitor run type excellent both in startability and operating efficiency can be obtained.
