  • Patent number: 8215624
    Abstract: A jig pallet for conveying a workpiece that is placed on it and has a portion to be worked. The jig pallet has a conveyance carriage (A) movable along a production line, a workpiece receiving member (B) provided on the conveyance carriage (A) and on which the workpiece is placed, a pressing mechanism (E) to be placed so as to face a peripheral section of a to-be-worked portion of the workpiece placed on the workpiece receiving member (B), and an opening/closing member (D) on which the pressing mechanism (E) is provided. When the opening/closing member (D) is closed, the pressing mechanism (E) presses a peripheral section of the to-be-worked portion of the workpiece from above, and when being opened, the pressing is released, enabling the opening/closing member (D) to be opened and closed, with one end of the conveyance carriage (A) functioning as the support point, and allowing the workpiece to be taken out.

  • Patent number: 8215004
    Abstract: A fabrication line that utilizes a jig pallet that is commonly used in processing equipment to efficiently finish and assemble semifinished products of plural shapes. The jig pallet includes a holding member D for holding a semifinished product W and an opening/closing device G1 for opening and closing the holding member D, and allows the semifinished product W to be mounted and dismounted by opening and closing the holding member D with the opening/closing device G1. The jig pallet is transported to processing equipment M1, M2, and M3 to allow the semifinished product to be processed in the fabrication line. An opening/closing driving device G2 that engages the opening/closing device G1 to open and close the holding member is provided along the fabrication line.

  • Patent number: 8161651
    Abstract: A process and assembly line for assembling a door-trim assembly in which resin-made door-trim parts are automatically fixed to a resin-made door-trim main body. Resin-made door-trim parts and deformable members associated therewith are temporarily installed to a resin-made door-trim main body. In a deforming processing unit (3), an electrically operated cylinder (10) equipped with an ultrasonic oscillator (2) extends and contracts and is rotatable within a horizontal plane by a ball screw mechanism (12). To the deformable members of the resin-made door-trim parts temporarily installed on the resin-made door-trim main body, the ultrasonic oscillator (2) comes close in opposite relationship by driving of the electrically operated cylinder (10) and ball screw mechanism (12), and performs ultrasonic irradiation. Consequently, the deformable members are deformed and the resin-made door-trim parts corresponding thereto are fixed to the resin-made door-trim main body.

  • Patent number: 8089269
    Abstract: An annular magnetic encoder capable of detecting an absolute position precisely by specifying the shape of a magnetization pattern. The annular magnetic encoder (A) is of such a type that the magnetic poles (2a) of N pole and S pole are formed alternately at an equal pitch by magnetization along the circumferential direction of an annular magnetic body (2), an unequal pitch region (20) is provided at least one place in the circumferential direction of the annular magnetic body (2) corresponding to a plurality of magnetic poles (2a). The unequal pitch region (20) consists of one specific pole portion (2b) in the center and different pole portions (2c) located on the periphery thereof whose polarity is different from that of the specific pole portion.

  • Publication number: 20100276891
    Abstract: A combination seal is attached to a bearing comprising a fixed element and a rotating element which rotate relative to each other, so as to seal an inner side and an outer side of the bearing. The combination seal is comprised of a seal ring and a slinger. The seal ring is comprised of a reinforcing ring and an elastic seal supported by the reinforcing ring. A leading end side of the elastic seal, supported by the reinforcing ring extending toward the slinger, is brought into contact with a surface of the slinger, which is opposite to the seal ring, when the combination seal is attached to the bearing. During a combining work process, when combining the seal ring and the slinger to form the combination seal, a seal lip does not turn over and the seal lip can be held toward a predetermined direction without using a specific jig during the combining work process and without being particularly careful during performance of the combining work process.
