Abstract: PURPOSE:To provide a method which is capable of simplify manufacturing bipolar transistors having specified properties. CONSTITUTION:A collector semiconductor layer 3, a base layer semiconductor layer 4 and an emitter layer semiconductor layer 5 are formed on a semi- insulating semiconductor substrate 1. There is formed a window or a notch 1 which forces the base semiconductor layer to face the outside. Then, there is formed a window 12 which forces the collector semiconductor layer to face the outside as well. The surface of the region facing the outside is cleaned. Then, the outer base semiconductor layer having the concentration of impurities which provide a higher conductivity type compound with the base semiconductor layer on the collector semiconductor layer where the surface facing the window of the base semiconductor layer is cleaned, is formed in continuous contact with the cleaned side facing the window of the base semiconductor layer. Hydrogen plasma is used to clean the sides facing the window for the base semiconductor layer and the surface of the area facing the window of the second semiconductor layer for the collector semiconductor layer.

Inventor: HAYASHIDA WATARU
IPC: H05G1/66
Filed: 1992-04-15
Abstract: PURPOSE:To rotate the anticathode at the required minimum rotating speed in response to a load to be applied to the anticathode. CONSTITUTION:The minimum allowable rotation speed according to the really applied load is obtained at each time on the basis of the relationship between the load applied to an anticathode 10 and the temperature rise so as to rotate the anticathode at this minimum allowable rotation speed. The rotation speed of the anticathode is thereby lowered as low as possible to minimize the deterioration of a vacuum seal device and a water seal device of a rotating part.

Abstract: PURPOSE:To enable stable data reading and correct density variation correction by providing a device to perform at least, either of the function to allow the first standard sample to be read and adjust the offset of a reading device or the function to allow the second standard sample to be read and adjust the gain of the reading device. CONSTITUTION:A storage medium in which a 70% duty halftone pattern 119 as the first standard density sample and a 30% duty halftone pattern 192 and a 50% duty halftone pattern 193 as the second standard density sample are sent in an E direction. If the pattern 191 reaches a position of a reading unit 14, it reads the 70% duty halftone and the offset is adjusted so that the readout is 0. Next, if the pattern 192 reaches the position, the reading unit 14 reads the 30% duty halftone and the gain is adjusted so that the readout indicates a maximum value. After that, the reading unit 14 reads the density variation of the 50% halftone, sensing the pattern 193. Thus variation correction data is rewritten.

Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To achieve a uniform system enzyme immunity analysis method that has a low background value and can secure sufficient S/N ratio by allowing a ligand, an enzyme labeled ligand, an antibody for the ligand, and a second antibody for the antibody to react one another and measuring the change in the enzyme activity of the labeled enzyme in a reaction liquid. SOLUTION: A ligand, an enzyme labeled ligand, an antibody for the ligand, and a second antibody for the antibody are allowed to react one another, and the change in the enzyme activity of a labeled enzyme in a reaction liquid is measured, thus measuring the amount of ligand. The ligand with an antigen determinant being contained in a specimen, namely an antigen, is to be measured. The specimen includes blood, lymph, and urine. The enzyme labeled ligand contains a substance that shares the ligand with a light source determinant being subjected to enzyme labeling. By combining the enzyme labeled ligand with the antibody and then combining the second antibody, steric hindrance for the labeled enzyme is increased. The enzyme activity of the labeled enzyme in the reaction liquid can be measured by adding an enzyme substrate to the reaction liquid.

Title: Hammering tool
Inventor: KOBAYASHI NORIAKI
IPC: B25F5/02
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To easily discharge the dust heaped in a housing by providing a dust discharge port in the housing positioned at a side opposite to a fan in a motor in a direction, in which the gravity is applied when a hammering tool is operated. SOLUTION: A dust discharge port 2e is formed in a matching part 2d of a housing 2 positioned in rear of a motor while crossing the axial direction of a tip tool. With this structure, in the case of using a hammering tool, the dust can be discharged from the dust discharge port 2c by the vibration to be generated by hammering. In a case where the hammering tool is not used, when the hammering tool is directed upward, the dust can be discharged from the dust discharge port 2c by the dead weight of the dust itself. At this stage, the dust to be sucked by a fan is a fine and easily discharged from the dust discharge port 2c. Since the dead weight of the dust is larger than the force to be given by a little quantity of the air sucked from the dust discharge port 2c, the dust is fallen onto the dust discharge port 2c side.
