  • Patent number: 9227443
    Abstract: A recording head is configured to selectively eject ink droplets from nozzles. A head board is configured to control the recording head to operate based on a high-frequency signal outputted from a control board. A carriage is configured to move in a reciprocating manner, with the recording head and the head board mounted thereon. A belt-like cable connects the control board and the head board so that the high-frequency signal can be transmitted therebetween. The cable has such flexibility that the cable can change a posture following reciprocating movement of the carriage. The cable has a first surface facing in a thickness direction of the cable. The cable has a reflective layer at a part of each of both end portions of the first surface with respect to a longitudinal direction of the first surface. The reflective layer is configured to reflect an electromagnetic wave.

  • Patent number: 8151431
    Abstract: Technology which enables a first member and a second member to be fastened together strongly is provided. A bar-shaped section is formed on the first member, a hole is formed in the second member, and the bar-shaped section of the first member is pressure fitted into the hole of the second member. Here, the diameter of the circumscribed circle which circumscribes the cross-section perpendicular to the axis of the bar-shaped section is made greater than the diameter of the inscribed circle which inscribes the cross-section perpendicular to the axle of the hole. The diameter of the inscribed circle which inscribes the cross-section perpendicular to the axis of the bar-shaped section is made smaller than the diameter of the circumscribed circle which circumscribes the cross-section perpendicular to the axle of the hole.

  • Publication number: 20090159209
    Abstract: The plasma etching method first forms a coating film on the inner surface of the chamber. Next, an etching process is performed on a wafer under a condition in which the coating film is formed, and thereafter a reaction product adhered onto the coating film in the etching process is removed together with the coating film. Each of these processes is implemented at a frequency in which the condition of the chamber inner surface is nearly always the same at the time of initiating the etching process.
