  • Publication number: 20190227044
    Abstract: An artificial olfactory sensing system includes a sensor unit. The sensor unit includes a semiconductor device equipped with a transistor and a sensor cell in which an olfactory receptor is manifested on a lipid film. A proton adsorption film is formed on a gate electrode of the transistor. A physiological aqueous solution is disposed on the proton adsorption film. Then, the sensor cell is disposed in the physiological aqueous solution. A proton is adsorbed onto the proton adsorption film. When the olfactory receptor recognizes an odor molecule, the positive ions in the physiological aqueous solution flow from an ion channel of the olfactory receptor into the sensor cell. As a result, the proton is dissociated from the proton adsorption film into the physiological aqueous solution, and the potential of the gate electrode is changed.

  • Patent number: 9919403
    Abstract: When a polishing pad is attached to a polishing table, the polishing pad can be easily positioned on and attached to the polishing table and air pockets are prevented from forming. As a position guide member 130 is inserted into a guide hole 109 with an attachment surface of a polishing pad 108 downward, the polishing pad 108 is positioned on and attached to a polishing table 110. At this time, the guide hole 109 of the polishing pad 108 is guided by the position guide member 130 and the polishing pad 108 is easily positioned so as to match the upper surface of the polishing table 110 with the outer periphery thereof. Then, as release paper is gradually peeled off from a rear surface of the polishing pad 108, the portion where the release paper is peeled off is attached to the polishing table 110.

  • Patent number: 9421867
    Abstract: An output current of a DC/DC converter which serves as a step-down device for charging the low-voltage electric storage device is detected. Based on the detected output current and the efficiency of the DC/DC converter, the electric power consumed by an auxiliary equipment load that is connected parallel to the low-voltage electric storage device is controlled to make the efficiency of the DC/DC converter equal to or greater than a prescribed efficiency, so that the low-voltage electric storage device can be charged from a high-voltage electric storage device or an external power supply.
