Title: Piston ring for internal combustion engine
Inventor: MATSUURA MASAAKI
IPC: F16J9/10
Filed: 1985-09-10
Abstract: PURPOSE:To make sure of sealability despite simplicity in a manufacturing process, by forming a piston ring with a plastic member, and installing a metallic backup ring, which gives force in an expanding direction to this piston ring almost over the whole circumference, in the inner circumferential surface. CONSTITUTION:Since a piston ring 13 is made up of a plastic member having elasticity such as, for example, a Teflon (fluorpacarbon polymers) compound or the like the outer circumferential surface 13b is subjected to deformation and wear after the form of an inner circumferential wall of a cylinder bore 2 and forcedly pressed by expanding force of a backup ring 17. And, it is almost uniformly pressed whereby the occurrence of partial damage in the piston ring 13 is chaecked. In addition, the plastic member is lightweight so that the promotion of lightweightiness in a reciprocating part is attainable, thus fluttering of the ring 13 inside a piston ring groove 11 attributable to reciprocation of a piston 3 is hard to occur, and with this fact, a leak of blow-by gas and so on becomes reduced. Therefore, a manufacturing process is simple and positive sealability is enjoyed an, what is more excellent in durability.

Title: Charger for electrostatic coating
Inventor: ACHINAMI TOKUYUKI
IPC: B05B5/10
Filed: 1990-07-30
Abstract: PURPOSE:To prevent the generation of spark discharges when a high voltage is impressed on an automobile body being conveyed by connecting the high-voltage rail part of a current collecting rail for impressing a requisite high voltage on the body to the low-voltage rail part connected to a ground through a high-resistance booster part and laying an insulating rail part over the requisite length from the low-voltage rail part to the high-resistance booster rail part. CONSTITUTION:When an automobile body W arrives at a coating zone, a current collector 8 provide at the front end of an upper frame 7 is brought into sliding contact with a low- voltage rail part 1a. Since the low-voltage rail part 1a is grounded, spark discharges are not generated when the collector 8 is brought into contact with rail part 1a. The collector 8 transfers to an insulating rail part 1x from the low-voltage rail part 1a and moves toward a high-resistance booster rail part 1b. The correction 8 then passes the rail part 1x and transfers to the high-resistance booster rail part 1b, hence a voltage beings to be impressed on the body W, and the impressed voltage is increased as the collector 8 moved toward a high-voltage rail part 1c while in sliding contact with the high-resistance booster part 1b. When the collector 8 transfers to the front end of the high-voltage rail part 1c, the voltage impressed on the body W reaches a requisite value for electrostatic coating. As a result, the paint supply system of a coating machine need not be insulated.

Abstract: PURPOSE:To make it possible to mold under the condition that skin material is uniformly and extendingly spread and prevent flatting out of pattern from occurring by a method wherein a pressure air opening is provided on a cavity face, onto which the skin material of a mold is sucked. CONSTITUTION:At the stage that the outside part 3b of a skin material 3 starts to be sucked to the cavity face 19 of a mold 11 after its center part 3a has been sucked to the cavity face 19 during the suction of the skin material 3 to the cavity face 19 of the mold, a small quantity of air is fed from a pressure air opening 31 between the cavity face 19 and the skin material 3. Accordingly, the center part of the skin material 3 is temporarily floated up from the cavity face 19 and, during its floating, the outside part 3b is moved and extendingly spread to corner parts and side wall parts, resulting in uniformly elongating the whole skin material. Then, after a mold 11 is closed synthetic resin material is introduced in a cavity so as to integrally mold a molded item, onto the synthetic resin surface of which the skin material 3 is provided. Thus, the whole skin material is uniformly elongated and troubles such as the flatting out of pattern and the like can be solved.
