  • Publication number: 20170173935
    Abstract: Metal plates are placed on opposed surfaces of two heating plates, the metal plates are heated. Then, a hollow plate is placed between the two heating plates, and the two heating plates are moved toward each other. The metal plates, which are heated to a high temperature, are bonded to the outer surfaces of the hollow plate by thermal fusion caused by the heat of the metal plates. After the metal plates are brought into planar contact with the hollow plate, the heating plates are moved away from each other. The heating plates sandwich the hollow plate only for a very short time. Thus, the heat of the heating plates is not transferred excessively to the hollow plate.

  • Publication number: 20160088227
    Abstract: Provided is an ultrasonic motor that includes a vibrator to which a piezoelectric element is fixed and a friction member having a frictional contact surface with the vibrator. A pressurizing member pressurizes the vibrator toward the friction member using a resilient force of a coil spring. A pressurizing force setting unit transmits a driving force of a pressurizing force setting motor to a holding member and then sets the pressurizing force by altering an amount of deflection of the coil spring depending on the relative position of the holding member with respect to the pressurizing member. The friction member is driven relative to the vibrator by an elliptic vibration of the vibrator in a state where the projections provided on a vibration plate is brought into pressurized contact with the frictional contact surface of the friction member by the pressurizing force.

  • Patent number: 9007658
    Abstract: Color shift detection requires additional processing as compared to detection of other items, and thus increases the load on the inspection processing. Conventional inspection apparatuses have a problem that the processing speed associated with inspection is affected and the costs of the inspection processing apparatus are raised. In a case where an inspection setting specified by a user includes color shift detection (YES in S406), scan image data of a printed material for a test print is determined to be a reference (S407). Then, comparison is made between scan image data obtained by scanning the printed material associated with a print job and the scan image data of the printed material for the test print.
