  • Patent number: 11933183
    Abstract: A steam turbine valve abnormality monitoring system according to an embodiment includes a detection unit detecting the state of a steam turbine valve or a steam turbine valve drive device, a determination unit, and an abnormality processing unit. Based on the detected result of the detection unit, the determination unit determines whether or not an abnormality has occurred in the opening degree control of the steam turbine valve. The abnormality processing unit issues an alarm or issues a turbine stop command when the determination unit determines that an abnormality has occurred in the opening degree control of the steam turbine valve.

  • Patent number: 11760405
    Abstract: A handle in which a sensor layer capable of detecting grip is disposed on a gripping portion that is gripped at a time of steering. The gripping portion includes a core material, a covering layer formed of urethane foam, which is disposed by die-molding so as to cover a periphery of the core material, the sensor layer, and a protective layer covering the sensor layer. The sensor layer is formed of a mold coat agent formed of a urethane-based paint containing a conductive material. The mold coat agent is applied to a die surface of a molding die of the covering layer. At a time of molding the covering layer, the sensor layer formed of the mold coat agent is disposed on a surface side of the covering layer.

  • Patent number: 11492837
    Abstract: In order to notify a user of a vehicle of a sensor position in an easily understandable manner to easily open and close a vehicle door by an operation performed by the user of the vehicle, a vehicle door opening/closing device includes: a road surface projection unit configured to project a display representing a position at which shape identification is performed, on a road surface around a vehicle; a shape identification unit configured to perform identification of a shape of an object in a predetermined road surface range including the display projected by the road surface projection unit; and a control unit configured to drive opening or closing of a vehicle door when the shape that is identified by the shape identification unit for the object in the predetermined road surface range represents a shape of a foot portion of a person.

  • Patent number: 11061248
    Abstract: A noncontact operation detecting device includes a detecting means configured to be able to detect whether or not an object is present at each of a plurality of points to be observed, which are set in a space, an operation decision section configured to determine, on the basis of a detection result detected by the detecting means, whether or not a gesture operation has been performed, and an aerial image displaying device configured to be able to display an aerial image showing locations of the plurality of points to be observed, in the space.
