  • Patent number: 10340825
    Abstract: An initial position determination process and a rotation driving process are both attained. A motor includes a rotor having a permanent magnet with a plurality of magnetic poles and a stator having coils with a plurality of phases. A voltage signal generation part generates a voltage signal corresponding to an electric current flowing through each of the coils with the phases of the stator. A filter part includes a first filter and a second filter. The voltage signal is inputted to a comparator through the filter part. A control part controls such that the first filter whose filter constant is larger is selected when performing the initial position determination process of the rotor and the second filter whose filter constant is smaller is selected when performing the rotation driving process.

  • Publication number: 20190151921
    Abstract: A projector emits laser light, and an optical receiver includes a photodetector. When an upper table is lowered, a safety controller controls lowering of the upper table to stop, when it is determined that the optical receiver is in a light obstructing state in a period in which a condition is satisfied that a first distance between a tip of a punch and an upper end of a material is equal to or greater than a second distance between the tip of the punch and the photodetector, and controls the lowering to continue without stopping the lowering of the upper table even when it is determined that the optical receiver is in the light obstructing state in a period in which a condition is satisfied that the first distance is less than the second distance.

  • Patent number: 10222613
    Abstract: A display apparatus for a vehicle is provided with a display unit and a display position control unit. The display unit is capable of displaying information at plural different display positions. In an autonomous driving state of the vehicle, the display position control unit detects a position of a steering wheel and an eye position of a driver. When the display position control unit determines that information displayed by the display unit is obscured by the steering wheel as seen by the driver, the display position control unit causes the information to be displayed at a display position that is visible to the driver.

  • Patent number: 8754141
    Abstract: A method that produces heat-expandable microspheres includes the use of a shell of thermoplastic resin and a non-fluorine blowing agent encapsulated therein having a boiling point not higher than the softening point of the thermoplastic resin. The method includes a step of dispersing an oily mixture containing a polymerizable component, the blowing agent, and a polymerization initiator containing a peroxydicarbonate in an aqueous dispersing medium to polymerize the polymerizable component contained in the oily mixture. The resultant heat-expandable microspheres have a shell which is less apt to become thinner than its theoretical value, contain minimum amount of resin particle inside their shell, and have excellent heat-expanding performance.
