  • Patent number: 9176619
    Abstract: A connection portion extends from an operation substrate, and a retaining groove of an elastic body is retained in a retaining hole of the connection portion. When a shaft portion of a retaining member is inserted into a through hole of the elastic body and screwed into an internally-threaded hole of a panel, an upper elastic portion of the elastic body is interposed between the connection portion and a support portion of the panel, and a lower elastic portion of the elastic body is interposed between the connection portion and an facing member. When an operation surface of the operation substrate is pressed, the connection portion rotates in a direction and the upper elastic portion and the lower elastic portion of the elastic body are compressed, whereby an appropriate operation reaction force and an elastic return force can be exerted.

  • Publication number: 20140362038
    Abstract: A touch pad with an antenna includes an electrode, control means for detecting proximity and a proximate position of an object on the basis of a change in capacitance which is associated with the proximity of the object to the electrode, an antenna, and antenna driving means for supplying power to the antenna. When the proximity of the object is not detected, the control means controls driving of the antenna driving means to set an output of the antenna to an output during ordinary driving. When the proximity of the object is detected, the control means controls driving of the antenna driving means to attenuate the output of the antenna with respect to the output during ordinary driving or to set the output of the antenna to zero.

  • Patent number: 8734549
    Abstract: A gasification process is divided into three processes: a gasification furnace for carrying out gasification process by pyrolysis and gasification (pyrolysis gasification phase, first process), a combustion furnace for burning char to obtain calcined active chemical (char combustion phase, second process) and a gas purification furnace for purifying gasified gas (gasified gas purification phase, third process). Through heat transmission by the fluid heat medium and chemical reactions in respective phases by the chemical, the gasification furnace is independently controlled to a low or medium temperature (773-1073 K) which is required for gasification and which enables absorption of CO2; and the gas purification furnace is controlled to a high temperature (1073 K or more) required for gas purification.
