Patents by Inventor Kentaro Tsuruta

Kentaro Tsuruta has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11460798
    Abstract: A stored object detection device includes: a radar sensor which emits a radio wave and detects a reflected wave; a reflector which reflects the radio wave emitted from the radar sensor; and a detection target object storage amount detector which detects a storage amount of a detection target object in a container, based on a reflected wave of the radio wave that has been reflected on the container containing the detection target object, a reflected wave of the radio wave that has passed through the container and has been reflected on the detection target object, and a reflected wave of the radio wave that has passed through the container and has been reflected on the reflector.
    Type: Grant

  • Patent number: 8803038
    Abstract: An apparatus for image formation comprises a fixing unit, first to fourth switching units, a DC power supply unit, an accumulating unit, a charging unit, and a switching control unit. The first switching unit switches the state of connection between the fixing unit and a commercial power source. The DC power supply unit supplies another electric load of the apparatus than the fixing unit with DC power. The second switching unit switches the state of connection between the DC power supply unit and the commercial power source. The third switching unit switches the state of connection between the charging unit and the commercial power source. The fourth switching unit switches the state of connection between the accumulating unit and the electric load. Based on the state of conduction of the first switching unit, the switching control unit switches the states of conduction of the other three switching units.
