  • Patent number: 11345079
    Abstract: A liquid discharge apparatus to form a three-dimensional object with a plurality of layers of ink laminated includes a stage; a discharge head to discharge photocurable ink, toward the stage, for each layer in a height direction of the three-dimensional object; a driver to move the discharge head or the stage relative to the other; an irradiation device to cure the ink, for each layer, with curing light irradiation; and circuitry. The circuitry causes the discharge head to discharge the ink, according to slice data indicating a printing region and a non-printing region in each layer generated by sliding in the height direction of the three-dimensional object, corresponding to movement of the discharge head; and change, in each layer, illuminance of the curing light in the printing region and the non-printing region in accordance with a state of the printing region and the non-printing region indicated by the slice data.

  • Publication number: 20100274485
    Abstract: A communication unit communicates information via near-field wireless communications. An information generating unit derives a travel distance, by which a movable object moves in a predetermined time period, and generates travel information including at least the generated travel distance. A transmission control unit transmits the generated travel information to a portable navigation device via the communication unit. A GPS receiver receives a signal from a GPS Satellite. A current position deriving unit successively derives a current position according to the signal received by the GPS receiver. A travel information obtaining unit obtains the generated travel information. A position estimating unit estimates an estimated current position moved from a previous current position, which is previously derived by the current position deriving unit, according to the travel information obtained by the travel information obtaining unit.

  • Patent number: 7088304
    Abstract: An antenna coil includes an air-core coil wound helically in a plane and a plate magnetic core member inserted in the air-core coil to be approximately parallel with a plane of the air-core coil. The magnetic core member is formed by a soft magnetic metal, an amorphous or ferrite, or a composite member of a powder, flake and plastic, or rubber. The magnetic core member is formed by performing an injection molding operation or a compressing molding operation of the composite member. Alternatively, the magnetic core member is a magnetic coating formed by applying and drying the composite member. A non-magnetic conductive plate that has a conductivity is layered on a surface of the air-core coil through which the magnetic core member is inserted. The conductive plate is made of a copper, a copper alloy, an aluminum or an aluminum alloy having 0.01 to 2 mm thickness. The antenna coil is operated by relatively high frequency while it is rigid relatively.
