Title: Power source controller for inverter type resistance welding machine
Inventor: SAITO MINORU
IPC: H02M7/48
Filed: 1987-07-16
Abstract: PURPOSE:To prevent a small-sized and lightweight welding transformer from being damaged by detecting the magnetic saturation based on the variation of a primary current of the welding transformer to control a switching action of an inverter according to a detected signal. CONSTITUTION:In order to detect the magnetic saturation of the welding transformer 20, a current sensor 38 is provided to wiring between a primary coil of the welding transformer 20 and an output terminal of an inverter circuit 18. Then, an output signal of said current sensor 38 is supplied to a primary current detection circuit 40 which supplies an output signal SI corresponding to the primary current Ip to a magnetic saturation detection circuit 42. The magnetic saturation detection circuit 42 produces a detected signal MS indicating a magnetic saturated state of the welding transformer 20 and in response to said signal MS, a pulse width control circuit 32 controls the switching action of the inverter circuit 18 so as to regulate the pulse width of the primary current Ip when the magnetic saturation is generated.

IPC: H03F3/343
Filed: 1980-12-17
Abstract: PURPOSE: To stabilize the current output, by connecting transistors in series respectively to plural trnsistors which have bases connected commonly to the base of one transistor.  
     CONSTITUTION: Transistors (TR) Q 2 ' and Q 3 ' are connected in series to TRs Q 2  and Q 3  which have bases connected commonly to the base of a TR Q 1  of the diode constitution.

IPC: B08B7/02
Filed: 1982-10-13
Abstract: PURPOSE:To remove the adhered dust efficiently by a method wherein a vibrator is attached to a heat transfer tube to vibrate it without providing the tube with a strong impact force. CONSTITUTION:The temperature of fluid to be heated and heating fluid are detected always and the results of the detections are inputted into a control box 5, memorizing them and outputting command signals. A temperature difference between the fluid to be heated and the heating fluid, under a condition that the dust is not adhered to the surface of the heat transfer tube 1, is memorized previously into the control box 5, and when the value of the actually measured data of the temperature of the fluid to be heated with respect to the same of the heating fluid is lower than a specified value, the control box 5 decides that the dust is adhered to the tube and outputs an operating signal to the vibrators 4, 6 to effect the dust removing work. In this case, if displacement sensors 11, 12 are attached to vibration transmitting rods to measure the displacement and the number of vibration and the feedback of the results of them are fed into the control box, the control of the dust removing work may be more facilitated.
