Title: Manufacture of semiconductor device
Inventor: KONO MICHIHISA
IPC: H01L29/205
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To enable manufacturing an HBT in a state such that variations of characteristic is restrained. SOLUTION: A resist pattern 108 is formed on a semiconductor layer, which is selectively etched by using the resist pattern as a mask. Thus, a mesa type cap layer 107a is formed under the resist pattern 108. In this case, the work is performed by wet etching using solution composed of citric acid and hydrogen peroxide. The semiconductor later in a region under the mask pattern is scarcely etched because the side surface only is exposed to the etching seed in the case of formation of the cap layer 107a. As a result, the cap layer 107a is formed almost the same form as the mask pattern, and reproducibility of emitter dimension can be maintained to be high, so that an HBT can be manufactured in a state such that variations of characteristic can be restrained.

Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To smoothly continue paper feeding by a simple operation when the kind of paper sheets to be fed are changed in the paper feeder of a friction separation roller system using a feed roller and a reverse roller. SOLUTION: The pressure-contacting force of a reverse roller 8 against a feed roller 7 is freely changed and the pressure-contacting force and the paper sheet returning force of this reverse roller 8 are increased/decreased based on a negative relationship. Thus, when the kind of paper sheets 1 to be fed is changed, the pressure-contacting force and the paper sheet returning force of the reverse roller 8 necessary for properly feeding the paper sheets 1 are easily set. Also, since it is not necessary to greatly increase the paper sheet returning force or the pressure-contacting force of the reverse roller 8, a compact driving device is used for the reverse roller 8 and the paper feeder is miniaturized and reduced in weight.

Title: X-ray power source device
Inventor: HINO HIROBUMI
IPC: H05G1/10
Filed: 1982-03-05
Abstract: PURPOSE:To improve the linearities of the non-load voltage and the tube voltage as well as the strain of the output voltage of an X-ray power source device by locating a power-source-impedance controlling resistor, which equalizes the source impedance  irrespective of the position in which the X-ray power source is installed, on the secondary side of a voltage-control transformer. CONSTITUTION:An autotransformer 3 controls the voltage of an a.c. power source 1,  and applies the controlled voltage to a high-voltage transformer 5 through a resistor 2  and a switch 4. The output of the transformer 5, after undergoing a full-wave rectification carried out by a rectifying circuit 6, is applied to an X-ray tube 7. Since the resistor 2 is located on the secondary side of the autotransformer 3, the resistance of the  resistor 2 seen from the secondary side of the autotransformer 3 becomes constant irrespective of the secondary voltage of the autotransformer 3. As a result, loss caused  in the resistor 2 becomes constant as far as the tube current is maintained constant  even when the secondary voltage changes, and the linearities of the non-load secondary  voltage and the tube voltage can be improved. In addition, the strain of the output  voltage can be suppressed by damping vibrations which are causd due to the leakage  inductance of the transformer 5 and the electrostatic capacity of a high-voltage cable.

Abstract: PURPOSE: To lower the activation temp. of a getter and to reduce the energy loss in the activation process of the getter by mixing powdery titanium with an oxidizing agent in such a ratio that prescribed heat of oxidation is generated and pelletizing the resultant mixture. CONSTITUTION: This getter 1 is obtained by mixing powdery titanium with an oxidizing agent such as powdery titanium oxide, powdery barium peroxide, etc., in such a ratio that a prescribed exothermic reaction is caused by heating the resultant mixture with a heater, and press-forming the mixture into pellets having a prescribed shape.
