Title: High frequency power supply
Inventor: KATO TSUTOMU
IPC: H01L21/302
Filed: 1993-05-19
Abstract: PURPOSE:To obtain a high frequency power supply from which no excess high frequency power is outputted even when no discharge is caused in a load. CONSTITUTION:An incident high frequency power Pf and a reflected high frequency power Pr from a coupler 5 are fed to a divider 9, and its output is fed to an adder 10, in which the output is added to a level signal V2 from a level signal source 11. When discharge in the load is stopped, the relation of Pf=Pr is set and an output of the divider 9 reaches 1V. When a set value of the level signal source is set to be -5V, an output of an adder 10 is positive voltage and a transistor(TR) T is turned on. A signal of the reflected high frequency power Pr in this state is short-circuited and an output of a subtractor 8 becomes a signal of only the incident high frequency power Pf. Thus, the control to make the incident high frequency power Pf constant is executed. When discharge is caused in the load and an output voltage of the divider 9 reaches 5V or over, an output of the adder 10 becomes negative. As a result, the TR T is turned off and the control making the effective power constant is started.

Title: Thick film printed circuit
Inventor: TSUKAHARA MICHIYOSHI
IPC: H05K1/16
Filed: 1981-07-27
Abstract: PURPOSE:To prevent the exudation of resistor paste from the air gap which the wiring pattern, stencil screen and substrate form, by a method wherein the thickness of pattern conductors of printed circuits on the insulated substrate is minimized. CONSTITUTION:A stencil screen is laid on a ceramic substrate (5) and such paste (2) as Au and the like, is pressed and moved to print a wiring pattern and burned thereupon. Then, a stencil screen (1) is laid thereon and a resistor paste (6) is pressed and moved by a gum squeegee (5) to print. As the wiring pattern (2) is of some 1m of thickness, the triangular air gap (4) is extremely small, the paste (6) flowing into said air gap (4) is very little and in case of flowing out from said air gap by ways of viscosity it hardly exudes. Therefore, the hole of screen can be reflected conscientiously to print the resistor (7) in a well-ordered way. On burning up continually a thick film printed circuit can be completed. According to this constitution, in a high density pattern the wiring pattern does not come in contact with adjacent resistors to provide a high quality thermal head.

Abstract: PURPOSE:To transform voltage in a wide range by providing a reactor, an energy discharge circuit to discharge energy accumulated in it and an error amplifying transistor, etc., and making a transistor execute either chopper action or linear action. CONSTITUTION:When the transistor Tr 13 is turned OFF, the energy accumulated in the reactor 14 is discharged to load through a diode 15 as shown by an arrow mark 27. Besides, the voltage of a smoothing capacitor 25 drops as well, and when it reaches a threshold level, the error amplifying Tr 21 is turned into an OFF state from an active state, and a base current controlling Tr 16 is turned ON, and subsequently, the Tr 13 is turned ON. Thus, the Tr 13 repeats ON and OFF, and oscillation is continued. When the voltage of a direct current power source 11 drops and gets near to the sum of saturation voltage between the collector and the emitter of the Tr 13 and the threshold level, the chopper action is stopped and the linear action is started. Thus, the voltage of the wide range from the voltage near to the voltage to be supplied to the load and up to the several times higher voltage than it can be transformed.
