Title: Manufacture of solenoid valve
Inventor: SAKANOUE KOUZOU
IPC: F16K31/06
Filed: 1993-11-12
Abstract: PURPOSE:To fix a ball valve body to the end of a plunger properly and without any gap by coupling and connecting the ball valve body to a recess at the end with resistance welding. CONSTITUTION:A plunger 18 is integrally formed to have a roughly columnar shape, and a coupling recess 23 is formed on the upper end thereof. A ball valve body 24 contacting and parting from a valve seat for opening and closing a flow passage 21 is fastened within the recess 23. The plunger 18 may be made of sintered metal or a general lump of metal. First, the ball valve body 24 is loosely coupled to the recess 23 and, then, resistance welding is applied thereto. As a result, the surrounding wall of the recess 23 melts due to the resistance welding, thereby jointing the ball valve body 24. In this case, a gap is not formed between the recess 23 and the lower half of the ball valve body 24, and the ball valve body 24 is held in such state as in contact with the whole internal surface of the recess 23. The body 24 may be made of ceramics other than steel. In this case, the plunger 18 made of sintered metal facilitates contribution all the more to the achievement of light weight.

Inventor: HASHIZUME SHINJI
IPC: B22F3/15
Filed: 1985-12-16
Abstract: PURPOSE:To directly form an intricately shaped body having a high density by using a small amt. of binder by forming a green compact from ceramic powder by using SI process, coating the entire surface thereof with rubber, etc. and subjecting the coated body to cold hydrostatic pressurization. CONSTITUTION:The ceramic or metallic powder is kneaded in the presence of an extremely small amt. of a high-polymer binder and water added thereto to prepare a slurry having a high viscosity (about 10<3>-10<5> poises). The slurry is injected by an injection molding machine into a mold made of a porous body under about 40-400kg/cm<2> pressure and the pressure is held to dehydrate the slurry and to form the green compact in which the powders are entangled with each other. After such green compact is dried, a coating material such as rubber is coated thereon by spraying etc. to about 2-3mm. The green compact is then subjected to the cold hydrostatic pressurization (CIP) and is calcined. The smaller amt. of the binder is thereby required and the ceramic or metallic powder is molded with the shorter time for the calcination over the entire part.

IPC: A46B13/02
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To perform neat finishing without a polishing flaw conspicuous, by giving a swivel motion to perform composite rotary action during one-way rotation. SOLUTION: When an eccentric cam shaft is rotated around in the clockwise direction with a carrier plate, a rotary work shaft 4 is rotated in the clockwise direction through a connection lever 5. By on-its own axis rotation of this eccentric cam shaft, when an eccentric cam 2 is rotated around an axial center of the eccentric cam shaft, the rotary work shaft 4 performs fixed angle reciprocating rotation in the clockwise and counterclockwise direction through the connection lever 5. As a result, in the rotary work shaft 4 and its tip end mounted polishing member of buff 29, sand paper, polishing grinding wheel, brush, etc., compound rotation making a swivel motion in the clockwise counterclockwise direction at a different speed, though rotating in the clockwise direction, is generated. A polishing flaw becomes discontinuously short and inconspicuous, and finishing is also improved.
