Title: Firing circuit device of semiconductor element
Inventor: CHIKAI SATOSHI
IPC: H02M1/06
Filed: 1993-06-04
Abstract: PURPOSE:To make a device small by installing a transistor whose base side is connected across a first resistance and a switching element, whose emitter side is connected across a second resistance and a first power supply and whose collector side is connected to the switching element. CONSTITUTION:When an ON instruction is introduced from a drive input terminal 39, a third transistor 37 and a first transistor 34 are turned on, a driving instruction is introduced simultaneously, and a second power supply 28 is driven. At this time, since the voltage of the power supply 28 is higher than that of a first power supply 27, a current flows to a gate terminal 29 via the transistor 34. The current is increased gradually, it becomes definite, and it functions as an overdriving current. Then, when the supply period of an overdriving power supply is finished, a stop instruction is introduced from the drive input terminal, and the power supply 28 is stopped. After this point of time, a current flows to the gate terminal from a firing DC power supply for the power supply 27, but it is at a steady-state driving current value. Consequently, the current in two stages can be made to flow to the gate terminal by the transistor 34 only, and the title device can be made small.

Filed: 1981-08-28
Abstract: PURPOSE:To obtain the IC having the resistance element of resistance value extending over a wide range and capacitor by forming a Ta thin-film having property required by repeating sputtering as necessary and using the thin-film.

Title: Surface flaw detection method for steel material
Inventor: TSUBOTA KAZUYA
IPC: G01N25/72
Filed: 1978-11-02
Abstract: PURPOSE: To ensure a simple detection method for the flaw on the steel material surface by quenching only the surface of the steel materials after giving a short- time contact of the cooling bar to the surface of the steel material under the hot processing and then detecting through magnification the temperature difference between the faulty area and the normal area.  
     CONSTITUTION: The diagrams show the scab, the bite-in flaw, the vertical crack and the concave flaw each. The cooling bar is made to touch surface 1 of the steel material under the hot processing to give quenching only to the surface layer part. Thus faulty area 2 seems darker or more reddish than normal area 3 since area 2 has the different electric heating condition due to the dislocation of the metal structure. As a result, the presence of the flaw can be detected distinctively.

IPC: H01P3/16
Filed: 1994-06-17
Abstract: PURPOSE:To provide a directional coupler for an NRD guide in order to facilitate the gap adjustment and the positioning and also to reduce the occupied area of the coupler. CONSTITUTION:A linear part 7 is inserted into a part where the distance is smallest in reference to the connection between the main and secondary lines which construct a directional coupler. Thus the connection part of both lines is equal to the part 7 that includes even a line side face. Then the bend having the smallest curvature radius is equally divided into (n) parts among those bends that are designed as the bends having no loss. These bends that are equally fractionated into (n) pieces are all continuously arranged again in a single-stroke writing way so that a curved line is formed. When a signal is inputted at the input end of the curved line in an LSM mode, a curve part 4 is formed for the branch part secondary line of a coupler line in a range covering the input end of the curved line through a single point where the signal mode is reset in an LSM mode on the curved line.

Abstract: PURPOSE:To decrease power consumption at pulse signal transmission, by connecting a matching resistor across primary winding of a coupling transformer, connecting transistors (TRs) between other end of the resistor and power supply and ground, and controlling the conduction of a current. CONSTITUTION:A primary winding of a coupling transformer 20 is connected with matching resistors 13 and 14 and TRs 21-24 are connected respectively between other ends of the resistors 13, 14 and ground and between the ends and a power supply, and a load 12 is connected to the secondary winding of the transformer 20. Signals (a), (b), (d) and (e) are applied to the bases of the TRs 21-24 via resistors 15-17 respectively.
