IPC: C08J7/00
Filed: 1997-10-29
Abstract: PROBLEM TO BE SOLVED: To obtain the subject resin board capable of suppressing the rise of the gloss reversion, that is, glossiness in the time of thermoforming by irradiating ultraviolet trays to a methacrylate resin board having a matted surface. SOLUTION: This resin board is obtained by irradiating ultraviolet rays to a methacrylate resin board having a matted surface to which a minute ruggedness pattern called a grain and a crepe is provided. A high-pressure mercury light with about 120 W/cm output level is used as a ultraviolet ray source, for example, set at the height of 300 mm from the surface of the methacrylic resin while, for example, moving the methacrylic board at a speed of 1 m/min and irradiating the methacrylic board, for example, so that the exposure dose may be 1500 mJ/cm<2> . The temperature at the time of the irradiation is preferably from the room temperature to 50 deg.C.  The resin board like this can prevent the disappearance of a matted pattern because a retention of the matted state after thermoforming is excellent, and can maintain the matted pattern nearly same as that of before heating and molding and has high-level feeling and glare shield activities.

Abstract: PROBLEM TO BE SOLVED: To restrict wear-elongation of a chain, improve the fatigue strength of the chain, and reduce vibration noise by applying shaving operation to at least one face out of engaging faces to be engaged with a sprocket, inner faces of pin holes, back face of a plate. SOLUTION: On a plate 1, two pin holes, and engaging faces 3, 4 to be engaged with a sprocket when the plate is incorporated into a silent chain 1, are provided. The plate 1 is formed by stamping out a blank material, and after the engaging faces 3, 4 are stamped out to be formed, shaving operation S is applied to the engaging faces. Thus, squareness of the engaging faces of the plate 1 in relation to the plate-plane is improved, and when the chain is organized, the pin hole 2 and the pin are in parallel-contact with each other in order for any unbalanced load not to be applied, since the plate 1 abuts against the sprocket wheel face when the plate is engaged with the sprocket. Consequently, wear-elongation of the chain is restricted, and vibration or noise caused when the plate and the pocket are engaged with each other, is reduced.
