Abstract: PROBLEM TO BE SOLVED: To prevent noise by an electric motor and its other operation part by preventing a temperature rise in the inside of a crankcase and the electric motor in a reciprocating piston type gas compressor. SOLUTION: A cylinder of a sealed state and an electric motor case of a sealed state of having a gas introducing hole in an outside end part, are ventilably and continuously arranged in the crankcase of a sealed state. Gas is sucked from the gas introducing hole 7 of the electric motor case 36 by reciprocating a piston 14 inserted into the cylinder 14 by a crankshaft 13 by driving a driving shaft 11 integral with the crankshaft 13 arranged in the crankcase 6 by the electric motor built in the electric motor case, and is introduced into the crankcase 6 via the electric motor 10. The gas in the crankcase 6 is sucked and pressurized to the front side of the piston 14 in the cylinder 1, and is sent out of the tip of the cylinder 1. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To easily coat an exposed flow path made of Al material with anticorrosive metal by fitting an anticorrosive metal-made bush with press or driving into a coating material flow path for feeding the coating material in circulation to an automatic gun main body made of Al alloy casting via a manifold. SOLUTION: Coasing material feed circulation flow paths 1a, 1b are bored on the automatic gun main body 1 of the automatic manifold shaped gun, and a center flow path 5a for coating material is bored on a casting material 5 cast in the main body 1, and a coating nozzle is screwed at the tip and also a needle valve 9 is set on the center part. At this time, the anticorrosive metal- made bushes 3, 4 are fitted to the coating material feed circulation flow paths 1a, 1b to be made to communicate with flow paths 2a, 2b of the manifold 2 and the tip 3b of the bush 3 is airtightly force-fitted into a communication hole with the center flow path 5a for coating material. Also a recessed groove 1c is formed at the rear part fitted with the bush 3 and the airtightness of the communication part of the flow paths 2a, 2b of the manifold 2 is kept through O-rings 6, 7 fitted to the recessed groove 1c.

Abstract: PROBLEM TO BE SOLVED: To comply with a request to obtain an adequate amount of spray corresponding to the size of a coating pattern in a simple structure and to obtain always an adequate atomizing-condition without any special sense or skill so as to solve such a problem that when an air spray gun which atomizes a coating and sprays it over an appropriate pattern by compressed air is used by adjusting the size of the pattern, at a coating position the change of only the size of the pattern without changing the amount of spray will vary the thickness of the coating film and produce an uneven finish. SOLUTION: The spray gun is constituted in such a way that the movement position of an adjusting knob of a pattern regulator is interlocked with the movement of a trigger in the spray gun operation and the margin of the trigger is enlarged corresponding to the enlargement of the pattern, whereby the opening of a coating valve interlocked with the trigger is enlarged.

Abstract: PROBLEM TO BE SOLVED: To solve the problem that a part of the paint jetted from a paint feed pipe is sprung back to form the scattered particles when an extremely large amt. of the paint is needed in the rotary electrostatic coater, and defective coating is caused. SOLUTION: The paint outlet hole 14 of a paint feed pipe 15 is set at right angles with respect to the axis of the paint feed pipe to smoothly disperse the paint jetted from the paint feed pipe on the inner periphery of a rotary cup 5 in the form of film, the total area of the outlet hole is controlled to at least 1.0 times the cross-sectional area of the paint inlet hole 16 of the feed pipe to decrease the speed of the paint jetted against the inner periphery of the rotary cup. Further, the paint outlet hole of the paint feed pipe is directed outward on a line connecting the rotating shaft and the feed pipe and at an angle of θ with respect to the rotating direction of the outer periphery of the cup.

Abstract: PROBLEM TO BE SOLVED: To obtain an air cap which is high in a spray pattern stability and lessens the splashes of mists by improving the boring structure of the air cap of an air spray gun. SOLUTION: This air cap is formed by forming the lateral air holes bored at a pair of the angle parts of the air cap as a main lateral air hole 2 and auxiliary lateral air holes 3a, 3b, setting the main lateral air hole 2 for flattening the pattern at a jet angle αto bring the air into collision approximately perpendicularly against the central jet flow and forming two pieces of the auxiliary lateral air holes 3a, 3b bored in the base parts of the angle part at the acute jet angle β with the splashes of the mists generated by the approximately perpendicular collision to form the auxiliary lateral air jets so as to hold the jet of the main lateral air hole, thereby forming the spray pattern of a well arranged elliptic shape.

Abstract: PROBLEM TO BE SOLVED: To provide an electrostatic coating apparatus which prevents the action of an operator to keep an electrostatic spray gun unconsciously apart from an optimum position for coating during electrostatic coating. SOLUTION: When a load current which changes approximately in proportion to the change in a spray distance is detected, and the load current is equal to or below the threshold which is the maximum load current within an optimum range of the spray distance, the operator is informed by the lighting of an alarm lamp or an alarm sound that the spray distance is out of the optimum range.
