Title: Forging method for tooth profile part
Inventor: SASAKI NAOKI
IPC: B21K1/30
Filed: 1987-02-17
Abstract: PURPOSE:To obtain a tooth profile part having no crack generation by forming annular recessed part adjoining to the outer peripheral face of a small diameter part on the face of the large diameter part of a blank step part in advance and escaping in the annular recessed part the excess metal caused by the pressure from the tooth line direction of the tooth profile at forging time. CONSTITUTION:The annular recessed part 6 adjoining with the outer peripheral face B of a small diameter part 1a and surrounding it on the face A of a large diameter part 1b at a step part 2 is formed in advance on the blank 1 forming the step part 2 with the small diameter part 1a and large diameter part 1b being co-axially connected. At the forging time of a toothed wheel 3, then, the excess metal 4 caused by the pressure from the tooth line direction of a tooth profile 3a is escaped into an annular recessed part 6 so as to cause no overlap of the excess metal 4 even if the tooth profile 3a is forged at low load. The tooth profile part causing no crack generation from the excess metal part can thus be manufactured.

Title: Flow rate controlling valve
Inventor: KINOSHITA TERUO
IPC: F25B41/06
Filed: 1988-02-17
Abstract: PURPOSE:To make an entire compact shape of a control valve and reduce an installing space by a method wherein a pilot valve is opened when a valve is opened and a pressure difference across a main valve body is substantially eliminated and then the main valve body is opened. CONSTITUTION:In case that a control valve is controlled from its fully closed state to its open state, a pulse is given to a solenoid coil 26. A rotor 21 is rotated by an angle corresponding to the number of pulses to pull up a rod 24 and a pilot valve 7. Only the pilot valve 7 is raised by a basing force of a pilot spring 9 and an opening end of a communication pipe 5 is opened. A pressure within an upstream side passage 1A guided to an interior part of a cylinder 2 is applied to a downstream passage 1B through an axial hole 5b and a communication 5a and its interior part is substantially equal to a pressure within a downstream passage 1B. Accordingly, a spring washer 8 is engaged with a stopper 10 by lifting a pilot valve 7 to cause the main valve 3a to be pulled up integrally. In this case, a valve seating force of the main valve 3a onto a valve seat 4 is sufficiently weakened, the valve can be opened with a low driving force, resulting in that a small-sized pulse motor can be used.

Title: Method for partially coating base material
Inventor: HONDA TOMIYASU
IPC: B05C5/02
Filed: 1986-02-18
Abstract: PURPOSE:To uniformly and efficiently coat only a required part by decompressing the inside of a coating box and also feeding paint so that it exceeds the level of a coating port provided to the side wall and inducing paint to the required part of a base material which is brought into contact with the coating port under pressure and transferred. CONSTITUTION:Paint is fed so that it exceeds the level of a coating port 11 and on the other hand, the inside of a coating box 10 is decompressed by a decompressing means 30 and thereby outside air is sucked through the coating port 11 and paint is stored in the box 10 without being overflowed. In this state, in case of putting a base material on a guide plate 13 and bringing it into contact with the coating port 11 under pressure and transferring it, the suction of air is not performed and only the part exposed to the coating port 11 of the base material is coated by paint when the coating port 11 is completely closed by the part to be coated of the base material. Coated paint is scraped off in the edge part of a downstream side of the periphery of the coating port 11 and a coated thin film is formed. An easily-exchangeable adapter may be used in order to change the shape and the dimension of the coating port 11.
