    Abstract: To provide a decompressing jig that can apply pressure on a workpiece after a space for accommodating the workpiece is sufficiently decompressed and a method for applying pressure on a workpiece by using the decompressing jig. The decompressing jig 1 is configured by integrating a first member for decompression 10, a second member for decompression 20, a sealing member 30, a first member for preliminary decompression 40, and a second member for preliminary decompression 50. The first member for decompression 10 is formed by spreading a first sheet 12 made of a flexible sheet across a first frame 11. In the first frame 11 a path for suction 15 that is connected to a device for suction via a port for suction 14 and that is connected to a space S for accommodating the workpiece is formed.

  • Patent number: 8900397
    Abstract: The present invention is to provide an apparatus to manufacture joined laminated media and a method therefor. The joined laminated media that are manufactured from the membrane materials and that are joined by being pressed have no displacement, deformation of the membrane materials, or any defect in joining the boundary faces of the laminated materials, and are efficiently manufactured in a good yield. The apparatus can manufacture a joined laminated-media where the laminated media are placed in the housing space (S) that is formed by a pair of endless belts (15a, 15b) and the sealing member (24). The laminated media are then transported in a state where the laminated media are fixed by the pair of endless belts (15a, 15b) that are closely attached to the laminated media because the air is discharged from the housing space (S) through the discharge holes (17) and they are joined by being pressed in the hot-press section (11) and cold-press section (13).

  • Publication number: 20050212846
    Abstract: An apparatus is provided for ejecting liquid drops while eliminating a special sensor (a photosensor) and improve detection accuracy for abnormal ink drop ejection. When the detecting an abnormal ink drop ejection, a drive circuit outputs an actuator-driving voltage in addition to an original drive voltage with a contact of a changeover switch located in a first position. The original drive voltage causes the electrostatic actuator to be driven. Thus, the vibrating plate is vibrated, whereby ink drops are ejected. Thereafter, the electrostatic actuator is charged with a charge according to the actuator-driving voltage. The charging voltage corresponds to the residual vibration of the vibrating plate. Then, the contact of the changeover switch is switched to a residual vibration-detecting circuit. Thus, the residual vibration-detecting circuit is supplied with the charging voltage to thereby output a residual vibration waveform.
