Abstract: An ink-jet printer is provided and includes: a motor, generating a driving force that prompts an ink-jet head moving in a main scanning direction relative to a print object; a motor, generating a driving force by which the ink-jet head is moved; a motor pulley, being rotated by the driving force generated by the motor; a first belt wound around the motor pulley to transmit the driving force from the motor pulley toward the ink-jet head; and a decelerating pulley on which the first belt is wound around to be rotated by the driving force transmitted on the first belt. At least one of a group of motor-side teeth of the motor pulley and belt-side teeth of the first belt and a group of deceleration-side teeth of the decelerating pulley and the belt-side teeth of the first belt is a combination of intermeshable spur gear teeth and helical gear teeth.

Abstract: A panel for an airbag of an automobile is formed by integrally molding a cover body, which is made of a synthetic resin, with a main body, made of another synthetic resin. The panel includes a joint portion, joined with the cover body, and provided around an opening portion formed in the main body. The joint portion constitutes an overlapping portion in which an outer peripheral edge of the cover body is overlapped as being arranged on the inner side of an opening edge of the main body.

Abstract: Disclosed is a method of molding an automobile outer trim part, including the steps of: (1) providing a film or sheet comprising a colored layer composed of a propylene polymer composition and, laminated thereto, a clear layer composed of a propylene homopolymer, (a) heating the laminated film or sheet, (3) feeding the heated laminated film or sheet into a metal mold including a pair of dies, (4) closing the metal mold so that the laminated film or sheet is shaped into desired configuration, (5) loosing the closed metal mold, and (6) injecting a thermoplastic polymer onto the side of the colored layer of the metal mold so that the shaped laminated film or sheet is united with a substrate layer of the thermoplastic polymer.
