Title: Microwave plasma etching device
Inventor: OKUDAIRA SADAYUKI
IPC: H01L21/3065
Filed: 1982-02-26
Abstract: PURPOSE: To improve selective etching and to increase etching speed by providing a means of controlling the pressure of a gas for electric discharge in a  vacuum chamber and a means for selecting the kind of bias voltage to be applied depending upon whether the material of the surface of a sample is a semiconductor or a conductor or an insulator.  
     CONSTITUTION: A gas for electric discharge is introduced into a vacuum chamber 7, and the microwaves generated with a magnetron 2 by a microwave oscillating power source 1 and the magnetic field generated by a magnetic field coil 4 and a magnet 5 are acted upon the gas for electric discharge, whereby plasma 11 is generated and the surface of a sample 12 is etched with the active particles in the plasma 11. If the sample 12 is of materials other than insulators such as Si, Al, negative DC voltage is applied to a susceptor 10 from an external voltage source 13 to achieve selective etching and to increase etching speed. If the sample 12 is of insulators such as SiO 2 , Si 3 N 3  or the like, the pressure of the gas for electric discharge is controlled by controlling a gas introduction port 8 and a discharge port 9, and AC voltage is applied to the susceptor 10 from the power source 13, whereby the etching speed is increased.

Title: Differential amplifier equipped with gain switching circuit
Inventor: ARAI MINORU
IPC: H03F3/45
Filed: 1989-02-08
Abstract: PURPOSE:To decrease the fluctuation of an output direct current level by controlling the turning-on and off of 7th and 8th transistors by switching the voltage of a control terminal and switching a gain. CONSTITUTION:When a voltage higher than a control terminal C2 is impressed to a control terminal C1, 7th and 8th transistors Q7 and Q8 are controlled to be turned off and differential signals to flow to transistors Q9 and Q10 are synthesized. Then, a signal component is canceled and only a direct current component is remained. This direct current is distributed by transistors Q13 and Q14 and resistors R7 and R8 and flows to resistors R5 and R6. When the transistors Q7 and Q8 are turned on, a current I2 of a constant current source CS2 is distributed by transistors Q3 and Q4 and flows to the resistors R5 and R6. Thus, the current of the constant current source CS2 is distributed to be half and flows to the resistors R5 and R6 regardless of the turning-on and off of the transistors Q7 and and Q8 and the change of the output direct current level is eliminated.

Title: Discharge excitation short pulse laser device
Inventor: HARUTA TAKEO
IPC: H01S3/041
Filed: 1985-02-18
Abstract: PURPOSE:To obtain the good-quality laser beam without the unevenness in intensity by arranging one of a pair of principal discharge electrodes, i.e., the aperture parts of an aperture electrode in a manner the discharge bars overlap at least in the part a laser beam passes among the space sandwiched by the pair of principal discharge electrodes. CONSTITUTION:Apertures 19 are arranged over the entire surface of an aperture electrode 8 and the position is so determined that when an arbitrary assumed line parallel to the optical axis of the laser beam is arranged on a surface of the aperture electrode 8 comprising plural apertures, the assumed lines passes the plural apertures 19. Namely the apertures 19 are arranged by a zigzag configuration. The voltage between the principal discharge electrodes and the auxiliary discharge electrodes increases steeply and produces an auxiliary discharge at first. A part of the electrons produced by this auxiliary discharge makes the principal discharge a uniform glow-state discharge and subsequently the pulse-like principal discharge is generated in the principal discharge space to excite a laser medium and to extract a laser beam. As a result, the discharge bars necessarily overlap and the unevenness of intensity of the laser beam can not be observed.

Title: High voltage generator
Inventor: FUKUI KAZUO
IPC: H03K3/53
Filed: 1985-02-18
Abstract: PURPOSE:To simplify easily the output voltage of a high voltage transformer by dividing the DC voltage of a controlling power supply which is proportional to a DC power supply at the primary side via a Zener diode and a resistance to obtain a duty ratio control voltage, and controlling the open/close of a switching element. CONSTITUTION:When the duty ratio control voltage VDT is applied to a terminal (-) of a pulse generating circuit 7, the control power supply voltage VA proportional to the AC voltage ea is divided via resistances R1-R4 and a Zener diode ZD1. Thus the voltage ea of an AC power supply 01 and an actual ON/OFF duty ratio of a switching element and therefore the product of an ON period TON are kept constant with the generator 7. In other words, both the duty ration and the product of the ON period are kept adversely proportional to each other. Thus the control input that eliminates the change of the output of an ozonizer due to the variance of the input of the power supply is applied to said output of the ozonizer despite said variance of the power supply input. In such a way the output even with no conventional detection of current of a primary winding is stabilized.

Filed: 1980-03-11
Abstract: PURPOSE:To accurately and early detect a leak of a cooling liquid circulation system in a high pressure gas atmosphere by measuring the change in the natural frequency of the pipe in the circulating system which is caused by mixed gas bubble due to the leak. CONSTITUTION:To detect a leak in a cooling liquid circulation system in a high pressure gas atmosphere such as a cooling system for the tuyeres of a blast furnace, a bypass route 4 is installed to the cooling water circulation system for on object 2 to be cooled. The cooling water is cleaned with a strainer 7 installed to the route 4; the flow rate, temperature, and pressure are measured with a flow meter 8, thermometer 9, and pressure gauge 9P; and a leak in the cooling water circulation system is detected by a leak detector 10. The detector 10 consists of a U-pipe connected to the route 4 and passes the cooling water. If a leak occurs, bubbles are formed in the cooling water, and the presence of bubbles changes the natural frequency of the U-pipe. This change is measured and monitored by an indicator 13, alarm 14, and recorder 15, effecting an early and accurate leak detection in the circulating system 3.
