Title: Automatic welding method
Inventor: OOTA SHINSUKE
IPC: B23K9/022
Filed: 1985-06-26
Abstract: PURPOSE:To enable the instantaneous execution of a main welding without relying on a tack welded bead by depositing and growing alternately a molten metal at both sides of a groove wall in a butt welding, by bridging the molten metal at the both sides and by performing the main welding from the position of the bridged molten metal. CONSTITUTION:A torch 14 is displaced to one side from the center position by an adequate quantity for a welding machine control device by a host computor. the computor outputs to the control device the welding conditions of not feeding a filler wire and starts the welding. The computor returns smoothly to the groove center position direction by adequate quantity the position of the torch 14. The welding conditions are outputted then with the feeding of the filler wire and the position of the torch 14 is rapidly returned to the groove center position. Now a molten metal 19 is alternately deposited and grown on the groove wall at both sides under the welding conditions of synchronous pulse and the bridging of the molten metal 19 is completed. The conditions of the main welding are then outputted and simultaneously the signal for rotation is outputted to a setting device and the main welding is started.

Title: Method for detecting disengagement and erroneous electricity conduction of electrode tip for spot welding
Inventor: KOYAKATA MASATO
IPC: B23K11/24
Filed: 1980-10-02
Abstract: PURPOSE: To detect the pull down of an electrode tip surely and prevent erroneous electricity conduction while the tip is held pulled down by providing means of detecting the insulation from an adapter and giving an alarm when said tip disengages  from said adapter.  
     CONSTITUTION: When an electrode tip 1 slips off from a tip holder 2 or a shank 4 owing to a certain inconvenience, the conduction of electricity is inhibited by an insulation plate 5 provided as an insulating means. On the other hand, a control circuit serving as a detecting means detects that electricity is conducted despite application of voltage by pressurizing the electrode. This control citcuit feeds a signal further to an alarm means, for example, an alarm device, and a signal machine (not shown), thereby announcing the pull-down of the tip 1. Hence, the operator knows the pull-down of the tip and suspends the subsequent work, where- by welding defect and the failure of the device owing to the absence of the tip are surely prevented.

Title: Prevention device of wind pressure in tunnel
Inventor: BUNTOU MUTSUROU
IPC: E21F17/00
Filed: 1993-06-10
Abstract: PURPOSE:To effectively prevent shock waves of air that are generated when high speed vehicle bodies, etc., pass through tunnels from being generated by reducing movements of wind pressure boards by a buffer and absorbing sound pressure by soundproofing material. CONSTITUTION:When a wind pressure which accompanies running of a high speed vehicle body, etc., hits a wind pressure board 2, the wind pressure board 2 moves microscopically at the moment, but the moving speed is reduced by a buffer 1. The wind pressure in the running direction of the high speed vehicle body, etc., is, therefore, weakened, and a reflected pressure is also weakened. Namely, a shock wave which is generated from a compressional wave, depending on a sonic velocity, is partially changed to a transmitted wave and the remainder is changed to a reflected wave by a buffer 1. Further, a soundproof material 3 which is provided on both front and rear sides of the wind pressure board 2 reduces sound pressure by its soundproof properties, and both transmitted wave and reflected wave are weakened. By providing and arranging an appropriate number of the wind pressure buffer means as stated above in the axial direction of a tunnel 01, shock waves generated from the running of high speed vehicle bodies are effectively prevented.

Filed: 1995-06-06
Abstract: PURPOSE: To obtain a measuring method in which a primary resistance value can be measured simply by measuring the output current of a three-phase inverter measuring and computing the primary resistance value of an induction motor on the basis of a specific expression. CONSTITUTION: A voltage control factor K and a phase θ0 in a PWM pattern are decided. At this time, the control factor K is decided by taking a voltage drop at a switching element into consideration so that a designated voltage can be applied to the terminal of an induction motor. Then, a voltage based on the PWM pattern is applied to the induction motor, it is detected that a current value has become constant (the change rate ΔI1 /Δt of a current is within a prescribed value) and a primary current value I1 is found by I1 =1/√3.√(Iu <2> +Iv <2> +Iw <2> ) (where Iu , Iv and Iw represent currents at a U-phase, a V-shape and a W-phase, respectively).  Then, the application of the voltage based on the pattern is cut off, and a primary resistance value R1 is computed on the basis of R1 =KVd /2√2.I1 ) (where Vd represents the output voltage of a rectifier). This operation is executed five times, the mean value which has excluded a maximum value and a minimum value is computed on the basis of a sample value, and the resistance value R1 is computed.
