Title: Semiconductor device and its manufacture
Inventor: YAMABE KIKUO
IPC: H01L21/76
Filed: 1989-10-30
Abstract: PURPOSE:To form an element separating area which is small in stress and high in reliability by burying an insulating silicon compound having a silicon ratio higher than the stoichiometric ratio in a groove for element separation. CONSTITUTION:This semiconductor device is constituted by burying an insulating silicon compound 5 having a silicon ratio higher than the stoichiometric ratio in a groove for element separation. A silicon nitride, silicon oxide, and silicon oxynitride can be used as the compound 5, but, of the three kinds of compounds, the nitride is the most suitable for the burying material. Since the lattice constant of the compound 5 is closer to that of a base layer 1, the compound can be buried without producing any stress against the layer 1 and, even after the compound is buried, the difference in coefficient of thermal expansion between the compound 5 and silicon substrate 1 becomes smaller. Therefore, an excellent element separating area which is small in stress can be formed.

IPC: G03G15/08
Filed: 1994-10-22
Abstract: PURPOSE: To provide an image forming device capable of always keeping the gap between a developer carrier and an image carrier constant and reducing the maintenance cost. CONSTITUTION: A developing unit is arranged in contact with a photoreceptor drum 1 on which an electrostatic latent image is formed, in the parts of the developing sleeve 6d and gap rollers 6b of the developing unit and the gap (d) between the developing sleeve 6d and the drum 1 is kept constant Toner housed in the developing unit is supplied from the developing sleeve 6d to the drum 1 and the electrostatic latent image formed on the drum 1 is visualized with the toner. Since the gap rollers 6b are made of a material having hardness higher than that in the contact part of the drum 1 with the gap rollers 6b, they are not worn by the drum 1 exchanged at prescribed cumulative working time intervals. Thus, the gap between the drum 1 and the developing sleeve 6d is always kept constant, a developer is stably supplied and a high quality image is formed.

Title: Repowdering technique for spent sintered hard alloy part by tin impregnation method
Inventor: NAKAMURA MITSURU
IPC: C01B32/949
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To reduce the transportation cost, to improve the quality and to increase the reutilization value by heating a spent sintered hard alloy (WC-Co base) part in a tin metal bath, allowing only Co to react with tin to take out as a metallic compound and to make the sintered hard alloy part brittle and easily pulverizing WC. SOLUTION: This sintered hard alloy to be broken is charged into tin heated to 1,050 deg.C and melted in a small sized simple quenching furnace and is held for a fixed time. The tin bathing time is different with the size of the alloy part and the impregnating speed of tin from the surface of the part to the center is fixed by the temp. condition. Next, the part is taken out from the bath and is cleaned while being stirred in concentrated hydrochloric acid for about 1 hr and as a result, the compound of tin with Co and excessively impregnated tin are washed out and the shape is broken. After the filtration and recovery thereof, the WC fine powder having 1.0-4.0 μm particle diameter, which is in nearly the same state as that before sintered, is obtained by pulverizing by a stamp mill or the like.
