Title: Safety operation control device of burner
Inventor: KISHIZOE YOSHIHIKO
IPC: F23N5/18
Filed: 1982-08-02
Abstract: PURPOSE:To enable to cope with the trouble even under the ON state of an air speed switch by a method wherein a predetermined combustion sequence does not proceed until the OFF state of the air speed switch is confirmed when a blower for feeding combustion air starts its rotation. CONSTITUTION:When the power supply of a power transformer 1 is put to work, current flows in a secondary side control circuit transiently through resistors 18 and 10 and a diode 23 into a capacitor 20, resulting in raising the voltage at the point Q of a programmable unijunction transistor (PUT) 17 until a predetermined set value is reached stably in a few seconds. In this time point, the temperature at the point to be controlled is low due to the condition that no combustion starts yet and consequently the voltage at the point (c) is higher than that at the point (b), causing a comparator 6 to invert and a relay 14 to turn ON. Consequently, the blower 13 for feeding combustion air starts its rotation. A few seconds later, when the rotational frequency becomes enough high, the air speed switch 16 is turned ON. However, if the air speed switch 16 is in such a trouble as that its ON state remains, PUT17 is driven to conduction, the voltages at the points A and G become nearly zero. Accordingly, the voltage at the point (c) of the comparator 6 is lowered through the diode 23, resulting in stopping the inversion of the comparator 6 regardless of the existing resistance value of a thermistor 9 or the existing temperature of the point to be controlled, resulting in remaining the relay 14 in OFF state and consequently checking the starting of combustion.

Title: Crater processing method for plasma welding
Inventor: NAGAOKA YOSHIYUKI
IPC: B23K9/00
Filed: 1985-06-20
Abstract: PURPOSE:To form a normal bead on the welding terminal part and to prevent a welding defect by gradually reducing the welding current after reducing it with gradations at the welding terminal part and by increasing the flowing quantity by changing the center gas from argon to helium as well. CONSTITUTION:The center gas is changed from argon gas to helium gas by opening a solenoid valve 9 and by closing solenoid valve 11 on reaching to a welding terminal part. It makes to reduce the key hole forming function as the center gas by reducing the mass of the center gas. The reason why the flow of the helium gas is increased is for displaying the reducing function of the arc of the center gas. The reason why the welding current is gradually reduced at the helium gas changing time is to make the heat gain same before and after the center gas shifting due to the heat again becoming large with the same current value and the helium gas ionization voltage being higher compared to that of argon gas. The current value is gradually reduced thereafter to obtain a good terminal bead.

Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To accurately generate a trigger and to minimize deterioration of a flicker in operation by setting the minimum output time of the trigger to a specific value when the zero crossing of a commercial power source can not be detected. SOLUTION: A fixing unit 30 detects the temperature of a ceramic heater 31 by a thermistor 32 and connects to an A/D port of a CPU 10 to monitor a temperature state. The CPU 10 obtains a zero-crossing signal CS from a zero-crossing detecting circuit 20, determines minimum duty width by a minimum duty width varying means 11 according to the cycle of the signal CS, and generates a trigger output signal asynchronously almost at the zero-crossing point of the commercial power source. A logical value with minimum duty width is 10 msec at a power source frequency of 50 Hz and 8.3 msec at 60 Hz, so the logical value is set to 9 msec between the two values, so that a power controller can be placed in operation even if a zero-crossing signal can not be detected, thereby minimizing the deterioration of a flicker.

Title: Production of welded h-beam
Inventor: INABA HIROTSUGU
IPC: B23K13/04
Filed: 1986-06-10
Abstract: PURPOSE:To prevent the generation of weld defects and to produce a welded H- beam having high joint strength and excellent quality by disposing insulating ferroelectric magnetic materials on both sides of a high-frequency current flow path on a web side to accelerate the heating of the part to be welded of a flange. CONSTITUTION:The insulating ferroelectric magnetic materials 6, 6 are disposed on both the right and left side of the high-frequency current flow path of the web 1. The spread of magnetic lines B of force to the right and left is suppressed by the effect of magnetic focusing so that the magnetic lines of force are changed to a longitudinally long shape and that the magnetic flux of a high density acts on the part 2' to be welded of the flange 2 in a narrow range. The electric current of a high density is, therefore, induced concentrically to the part 2a to be welded and makes an effective contribution to the heating to the flange 2 side. The difference in the heating state between the web 1 and the flange 2 is corrected and the heating on the flange 2 side is selectively accelerated according to the above-mentioned method; therefore, the melting thereof is surely assured.
