  • Patent number: 6032713
    Abstract: A first tension adjustor for adjusting the tension of a liner and a pitch measuring device for measuring the corrugation pitch of a first core board of a single-faced corrugated board are used. A first tension controller operates so that the tension acting on the liner is adjusted on the basis of the corrugation pitch of the first core board of the single-faced corrugated board. Further, a second tension adjustor for adjusting the tension of the single-faced corrugated board and a phase shift measuring device for measuring a phase shift between the corrugations of the first core board of the single-faced corrugated board and the corrugations of a second core board to be laminated to the first core board are used. A second tension controller operates so that the tension acting on the single-faced corrugated board is adjusted on the basis of the phase shift measured by the phase shift measuring device.

  • Patent number: 4929934
    Abstract: In a pressure-sensitive input apparatus comprising an X-coordinate detection resistive member connected to mutually parallel vertical electrodes and a Y-coordinate detection resistive member connected to mutually parallel horizontal electrodes, for detecting the position of a point depressed by a stylus or the like, by detecting changes in the resistance values of these resistive members, switches are provided for on-off control of the current flowing into or out of both ends of the X-coordinate detection resistive member and the Y-coordinate detection resistive member, and a voltage detection circuit detects the voltage between the X-coordinate detection resistive member and the Y-coordinate detection resistive member. Multiple inputs can be detected according to the results obtained from the voltage detection circuit when the currents are switched by the switches.
