Title: Directional control valve device
Inventor: ASAWA TAMIO
IPC: F16K11/087
Filed: 1993-12-28
Abstract: PURPOSE:To provide a directional control valve device without a liquid reservoir by devising it so that a valve element rotationally slides against a case between a columnar surface of the valve element and a circular arc sliding surface formed in a chamber of the case. CONSTITUTION:A resin made blocking member 18 having a circular arc sliding surface 18a facing against a columnar surface 16b of a valve element 16 is arranged in a fourth port 19 of a case 15. A circular arc sliding surface 14a facing against the columnar surface 16b of the valve element 16 is formed at a position between each of the first-fourth ports 11-13, 19 adjacent to each other in a chamber 14 of a case 15. The valve element 16 rotates and slides against the case 15 between the columnar surface 16b of the valve element 16 and the circular arc sliding surface 14a facing against the columnar surface 16b formed in the chamber 14 of the case 15. Consequently, fluid supplied from the first port 11 constantly and selectively flows out to the second port 12 or the third port 13 through an L letter channel hole 16a of the valve element 16. Additionally, intrusion of fluid to the fourth port 19 is prevented by the blocking member 18 having the circular arc sliding surface 18a.

Inventor: OONISHI MICHINARI
IPC: B22F5/08
Filed: 1996-12-16
Abstract: PROBLEM TO BE SOLVED: To surely form a sufficiently dense layer on the surface of gear parts by form-rolling. SOLUTION: A working blank 1 composed of a sintered body having the gear parts with plural teeth constituted of tips of teeth 1c, surfaces of teeth 1a and bottoms of teeth 1b is subjected to form-rolling by using a form-rolling die 2 meshable with the gear parts to make the dense surface of the gear part. At this time, in at least a part of the teeth, desirably, in many teeth as much as possible in the gear part of the working blank 1, the relations of the shape and the position between the working bland 1 and the form-rolling die 2 are defined so that the surfaces of teeth 1a and the bottoms of teeth 1b of the gear parts are press-contacted with the form-rolling die 2 and the interval between the form-rolling die 2 and the tips of teeth 1c of the gear parts becomes zero for execution of the form-rolling.  By the method, the thickness of the working blank 1 crushed with the form-rolling die 3 is surely fluidized into the inner part of the working blank 1 (pressurizing direction by the form-rolling die 2) and the dense layer can surely be formed on the surface of the gear parts press-contacted with the form-rolling die 2.

Title: Method for supplying washing water to spray-type multistage washing device
Inventor: HYODO TADAYOSHI
IPC: C25D13/00
Filed: 1989-12-27
Abstract: PURPOSE:To prevent fluctuation due to the lowering of a water level by steadily supplying a filtrate to a washing water tank from a filtrate tank and keeping the filtrate level at a specified valve when the washing device is stopped. CONSTITUTION:The electrodeposition coating soln. sent from the subtank 2 of an electrodeposition tank 1 is separated by a filter 3 such as a UF device into a paint component and a filtrate. The paint component is returned to the tank 1, and the filtrate is stored in a tank 4 and steadily supplied to a washing water tank T4 as washing water. The pumps 5 of the washing device are started to spray the washing water from a riser 6, hence the level of washing water in the washing water tank is lowered. When the level is detected by a control switch, the filtrate in the tank 4 is supplied to each washing water tank. Consequently, the time until overflowing is caused is reduced, and the quality of the washed article is improved.

IPC: H01L27/115
Filed: 1991-11-26
Abstract: PURPOSE:To reduce a parasitic capacitance, a leak current and a break down current, and also prevent a narrow channel effect. CONSTITUTION:A silicon substrate 1 is coated with a thick insulating film 9, and a silicon film is formed on the insulating film 9.
