摘要： An automobile bumper comprises a bumper face and a bumper beam constructed of members molded of thermoplastic resin. The bumper beam includes at least two members of thermoplastic resin having flanges for forming beam flanges together when the members are fused to each other, the beam flanges being fused to an inner surface of the bumper face. An FRP sheet is continuously heated in an atmosphere having a temperature successively lowered from a temperature higher than a resin melting temperature at which a resin of the FRP sheet is melted so that the entire FRP sheet is increased through successive heating stages to a temperature between the resin melting temperature and a resin degradation temperature at which the resin of the FRP sheet is degraded. Heaters are brought into close proximity with joining surfaces to be fused of at least two parts of synthetic resin with a prescribed spacing therebetween for melting the joining surfaces, and thereafter the melted joining surfaces are pressed against each other to fuse the parts together. At least one of the at least two parts comprises an FRP product made of glass fibers reinforced with a thermoplastic resin, the joining surfaces of the FRP product having a plurality of projections containing the thermoplastic resin only, the projections being melted when the parts are fused together.

摘要： An airbag rupturing groove forming apparatus forms an airbag rupturing groove excellent in invisibility even in a vehicular interior member having a hard substrate, while performing proper control of the thickness of the remainder of the airbag rupturing groove. A method also is provided for manufacturing the vehicular interior member. The airbag rupturing groove forming apparatus has a rupturing groove former for forming the airbag rupturing groove by protruding a metal blade at the back side of the vehicular interior member. First and second blade detectors confirm the presence or absence of the blade protruded into the vehicular interior member individually at detecting positions that are different in the thickness direction of the surface layer. An edge position deciding unit decides whether the blade is detected by the second blade detector, although the blade is not detected by the first blade detector.

摘要： A front face distance is obtained by measuring the position of a front face of an instrument panel held by an end effecter of a robot. An error on an optical axis, at the position of the front face is obtained based on the front face distance. Based on the error, the position of the instrument panel is adjusted so that a focal point of a laser meets the position at a predetermined depth defined with the front face as the standard. A back face of the instrument panel is irradiated with a laser to form a fine hole of a fragile section.
