  • Patent number: 9778765
    Abstract: There is provided a displacement sensor which can precisely detect the amount of displacement given by an operator. A touch sensor which is a type of the displacement sensor has a piezoelectric element, a voltage converting unit and a detecting unit. The piezoelectric element instantaneously generates a voltage proportional to a pressing force (the amount of pressing). The voltage converting unit converts the voltage generated by the piezoelectric element, into a voltage proportional to a transition determined based on a predetermined time constant determined by an impedance of a resistor of the voltage converting unit and capacitances of a capacitor and the piezoelectric element, and a pressing force. The detecting unit integrates output voltages of the voltage converting unit, and calculates the pressing force (the amount of pressing) based on an integration value.

  • Patent number: 9150798
    Abstract: Provided is a method of reforming a produced gas to reform tar contained in the produced gas from a gasification furnace. Quick lime comes in contact with a produced gas (3) from a gasification furnace (2) in a reformer (1) such that the quick lime absorbs carbon dioxide in the produced gas to generate calcium carbonate, and reforming reaction of the tar is performed with calcium as a catalyst using heat of reaction emitted during that time. In addition, as the calcium carbonate of the reformer (1) is supplied and burnt in a reforming agent regenerator (8), the quick lime is regenerated and supplied into the reformer (1) again. According to the above configuration, it is possible to provide a method and device for reforming a produced gas that are capable of simplifying equipment and operation thereof.

  • Patent number: 9102351
    Abstract: Construction of an electric power-steering apparatus is achieved that, by stably suppressing backlash of an output shaft 6a of an electric motor 5 over a long period of time, is able to stably reduce vibration and strange noise that occurs during operation. The front end section of the output shaft 6a and the base end section of a worm 7 are connected such that torque can be transmitted and such that relative displacement in the axial direction is possible. An elastic member 31 having an elastic force in a direction that separates the output shaft 6a and worm 7 is provided in the connecting section between the output shaft 6a and the worm 7. Due to the elastic force of the elastic member 31, together with the tandem arrangement contact angles, the preload is applied to a pair of ball bearings 14a, 14b that support the output shaft 6a with respect to the motor case 13 such that the output shaft 6a can rotate freely.

  • Publication number: 20150199061
    Abstract: A touch input device includes a touch panel, a push amount calculating unit and a touch detection signal generating unit. The touch panel includes piezoelectric and electrostatic sensors. The piezoelectric sensor outputs to the push amount calculating unit a push signal corresponding to a displacement amount obtained by pushing an operation surface. The electrostatic sensor outputs touch signals, corresponding to a touch and a non-touch, to a touch detection signal generating unit. The touch detection signal generating unit outputs to the push amount calculating unit the touch detection signals binarized according to the touch and non-touch state. The push amount calculating unit integrates differences between push signals and a reference potential during a touch state, generates a push amount detection signal and outputs the push amount detection signal. This unit resets a reference potential during a period in which a touch detection signal indicating a non-touch state is inputted.
