  • Patent number: 7105797
    Abstract: The current-voltage converting circuit converts an input current signal into a voltage signal, and the single-differential converting circuit converts the voltage signal into differential signals so as to output the differential signals. The first and second low-pass filters input outputs from the single-differential converting circuit, respectively, and the voltage-current converting circuit converts a difference between the output voltages from the first and second low-pass filters into a current signal. The current-voltage converting circuit inputs a voltage held in the hold capacitor as a control signal and converts the input current signal into a voltage signal using a current-voltage converting gain according to the control signal.

  • Publication number: 20060043042
    Abstract: In a counterweight attaching and detaching apparatus for a crane, the length of a suspension member is adjusted by an extendable member and links because the distance provided between the peak of a gantry and an upper surface of each of weights when the gantry is suspending the weight at a respective mounting position varies depending on the mounting position. In order to complement the adjustment of the length, different amounts of protrusion of rings from the upper surfaces of the weights are set so that the protrusion amount in the forefront weight is the largest and the protrusion amount in the rearmost weight is the smallest. This reduces the number of types of necessary links used in the suspension member to attach and detach the weights, and the number of operations of connecting and removing the links, and improves operation efficiency.

  • Patent number: 6812787
    Abstract: In a reference voltage generating circuit, in a first period, only a first switch is OFF and a maximum peak value Vmax of an input signal In is held at a node A of a first capacitor 1. Next, in a second period, a second and a third switches are opened, and a voltage difference between the maximum peak value Vmax and a minimum peak value Vmin is held at a node C of a capacitor string. At this time, the voltage held in a second capacitor of the capacitor string is added to the voltage held in the first capacitor, and the voltage at a node B is output as a reference voltage Vref. The input signal In is applied to one input terminal of a differential amplifying circuit, and the reference voltage Vref is applied to the other input terminal. When the voltages held at the nodes A and C have stabilized, the reference voltage Vref is generated.
