Title: Piston and manufacture thereof
Inventor: KAWABATA FUMIAKI
IPC: F16J9/00
Filed: 1985-05-01
Abstract: PURPOSE:To provide heat resistance and abrasion resistance for a ring groove by using a composite wire in which the hollow core part made of aluminium or Al-alloy is charged with Si powder and padding the part corresponding to the piston ring groove and forming the ring groove. CONSTITUTION:As for a composite wire 1, the hollow core part of a skin member 2 made of Al-alloy containing 5% Si is charged with Si powder 3 in a weight ratio of 30%. Said composite wire 1 is continuously supplied through an electricity feeding tip 7 by a feeding roller 6, and a recessed part 5 is padded to form a bulged part 8 through MIG welding. Then, a piston ring groove is formed through machining, and therefore, the superior heat resistance and abrasion resistance can be provided for the ring groove by forming a piston ring groove through machining, even if an expensive abrasionproof ring is not used in the conventional. Further, the machining for the ring groove is facilitated, and since the ring groove and the piston body are made integrally, the heat transmission performance at the boundary part is not reduced.

Inventor: MATSUMOTO YOSHIRO
IPC: B01J20/18
Filed: 1985-05-01
Abstract: PURPOSE:To obtain a detecting agent which enable the detection of a water removing capacity, by supporting cobalt chloride on a synthetic zeolite having pores exceeding the effective diameter of the cobalt chloride to make color change clearly even at the dew point of below -20 deg.C. CONSTITUTION:Synthetic zeolite can not support cobalt chloride unless the pores thereof exceed the effective diameter of the cobalt chloride. The boiling point of a solvent into which the cobalt chloride is desirable below 150 deg.C, since the cobalt chloride as being dried at about 200 deg.C for a long time will indicate changes in the color no longer depending on water when the solvent is removed after a solution into which the cobalt chloride is dissolved is impregnated with the synthetic zeolite. Then, the cobalt chloride solution is impregnated with the synthetic zeolite for a specified time. Then, the synthetic zeolite supporting the cobalt chloride is taken out of the solution to remove the solvent water at the temperature of about 150 deg. or below it in the air or a dry air. This can provide a detecting agent which enables the detection of a water removing capacity by a clear change in the color even at the dew point of -20 deg.C.

Filed: 1980-07-09
Abstract: PURPOSE:To form a diffused layer selectively by treating a semiconductor substrate having a doped silicon oxide film at a high temperature in an atmosphere of oxygen with a plasma nitride film pattern as mask after it is formed on the substrate. CONSTITUTION:A boro-silicated glass film 21 is formed on an N type semiconductor substrate 20 and a plasma nitride film 22 is formed thereon.
