Title: Drain valve device of washing machine
Inventor: SAITO KATSUYA
IPC: F16K1/32
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To prevent generation of a turbulent flow at draining time, and to shorten draining time by arranging a valve seat and a valve element to perform opening/closing operation on this valve seat, and forming the projecting part pointing to the tip part in the inflow side opening part of the valve seat in the valve element. SOLUTION: A drain valve device to drain washing waste water in a water tub 3 has a valve seat 15, a valve element 16 to perform opening/closing operation on the valve seat 15 and a valve element driving device 17 to operate the valve element 16, and the projecting part 19 pointing to the tip part is formed in the inflow side opening part 18 of the valve seat 15 in the valve element 16. When the valve element driving device 17 operates at draining stroke time, the valve element 16 is put in an opening state, so that the washing waste water is drained by passing to the outflow side opening part 20 from the inflow side opening part 18 of the valve seat 15 by water pressure of the washing waste water in the water tub 3.  Since there is the projecting part 19 in the valve element 16 when this washing waste water passes through the valve seat 15, the vertically colliding part of the washing waste water with the valve element 15 reduces, generation of a turbulent flow reduces, and resistance in the valve element 16 reduces, so that passing time to the outflow side opening part 20 from the inflow side opening part 18 is shortened.

Title: Method of dividing semiconductor device
Inventor: KUBO TOSHITAKA
IPC: H01L21/301
Filed: 1991-03-11
Abstract: PURPOSE:To expand the groove between the semiconductor chips of a wafer so as to make cuttings easy to flow in the widened groove by cutting the wafer while expanding an adhesive tape to which the wafer is stuck. CONSTITUTION:A ring claw 5 goes down, and an adhesive tape 2 is expanded, while, by vacuum suction holes 4, the wafer 1 being sucked by vacuum is fixed. A cutting blade 7 cuts in the adhesive tape 2 by approximately 20-30mum while rotating at high speed (2000-4000HPm) and cuts the wafer 1 completely and divides into semiconductor elements. At this time, the groove formed by the cutting is expanded, which prevents the interference between the cutting blade and the semiconductor elements. Furthermore, since the interval between the semiconductor elements is expanded, cuttings are easy to flow in the widened groove, therefore the cuttability improves.

Title: Steering lock
Inventor: ASADA TORU
IPC: B60R25/02
Filed: 1986-03-04
Abstract: PURPOSE:To prevent steering lock operation from abruptly occurring, by providing a pair of pawls for changing the direction of a latch, on the orbit of the latch which follows the motion of a plunger, and by enabling the latch to be selectively operated irrespective of the pawls. CONSTITUTION:When a solenoid 10 is energized to release a steering lock, a plunger 11 is withdrawn so that a retractable latch 14 is retracted. During this retraction, the latch 14 abuts against a pawl 17 so that the projection of the pawl 17 is engaged in a groove 15 while the latch 14 rotates, and therefore, the retraction of the plunger 11 is stopped. Meanwhile a spring 13 advances the latch 14 when the solenoid 10 is deenergized, so that the latch 14 abuts against a pawl 16 and then stops, resulting in release of a steering shaft 8. With this arrangement in which the latch mechanism is used to release a locking rod 7, the locking condition may be held even through a lead wire is broken.

Abstract: PURPOSE:To adjust flow of gas with a high accuracy by providing an adjusting valve which is capable of adjusting flow of gas to each sealing burner through the partial release of gas to the outside of path in the gas distribution path connected to each sealing burner. CONSTITUTION:A combustion gas is sequentially sent with pressure to a sealing burner 8 through a gas supply path 18, a center valve 24 and a gas distribution pipe 14 from a gas supply mechanism 19. In case flow of gas to the sealing burner 8 disperses and difference is generated in the firing power, a lock nut 35 is loosened and screwing of the adjusting screw 36 of the adjusting valve 30 is adjusted in accordanced with dispersion in flow of gas. Thereby, insertion of needle plug 37 changes and flow of combustion gas to be released to the outside through the release holes 34, 34. As a result, flow of gas to the sealing burner 8 can be adjusted. Flow of gas can be adjusted with higher accuracy as compared with the squeezing valve and fine adjustment can also be realized.
