  • Patent number: 8054093
    Abstract: There is provided a sensor threshold circuit that makes available a hysteresis width that is not dependent on the change in a threshold point. Since a bias current IB is generated by a threshold current IT and a threshold adjusting current ICONT, the threshold point is given by a coefficient A and a coefficient K and the hysteresis width |BH| is given by the coefficient K. Accordingly, when the coefficient K is determined, the hysteresis width |BH| is not dependent on the coefficient A and keeps a constant value. In addition, since the coefficient A depends on the resistance ratio, the threshold point is variable by changing a single resistor. Further, when the coefficient K is determined, the hysteresis width |BH| is also determined to be a single value with no variations in its value, no changes according to temperature, and no changes over time.

  • Publication number: 20060205298
    Abstract: A decorative laminate 40 in which a substrate 5 and a decorative sheet 10 comprising a base sheet 1 and at least a resin coat layer 2 provided on one surface thereof are laminated with each other, wherein the resin coat layer 2 is scraped partly or entirely. The antique style decorative laminate is provided thereby, with the process of work simplified and with the influence on the environment and human body decreased, moreover without installing equipment for exclusive use.
