  Terminal device and integrated circuit
  Patent number: 10420086
  Abstract: Degradation in reception performance due to interference is reduced while suppressing an increase in the amount of control information. There is provided a terminal device including; a higher layer that determines whether or not to apply NAICS; and a reception unit that receives downlink control information, in which, in a case where, with the higher layer, an indication that the NAICS has to be applied is provided, if the downlink control information is detected in a UE-specific search space, signal detection in compliance with the NAICS is performed, and in which, in the case where, with the higher layer, the indication that the NAICS has to be applied is provided, if the downlink control information is received in a common search space, signal detection in compliance with a linear scheme is performed.

  VIBRATION GENERATION DEVICE AND INPUT DEVICE WITH VIBRATION MECHANISM
  Publication number: 20180336985
  Abstract: A vibration generation device includes a plunger and a solenoid. The plunger includes a weight portion, a first biasing portion extending from the weight portion along a first direction and a second biasing portion extending from the weight portion along a second direction opposite to the first direction. The solenoid includes a first solenoid that is disposed so as to surround a part of the first biasing portion and operates the plunger in the first direction, and a second solenoid that is disposed so as to surround a part of the second biasing portion and operates the plunger in the second direction. The first solenoid and the second solenoid have a fixing portion for a vibration target, and the weight portion reciprocates between the first solenoid and the second solenoid to vibrate the vibration target.
  COPPER ELECTROLYTIC PLATING BATH AND COPPER ELECTROLYTIC PLATING FILM
  Publication number: 20180305833
  Abstract: The present invention provides a technology for, in copper electrolytic plating containing silver ions as an alloy component, obtaining a copper electrolytic plating film in which co-deposition of sulfur can be significantly suppressed and which is excellent in physical properties such as strength and hardness even after a high-temperature heat treatment at about 200° C. or higher. The present invention is a copper electrolytic plating bath comprising copper ions, an acid, chloride ions, and a complexing agent, wherein the copper electrolytic plating bath further comprises silver ions as an alloy component, and wherein methionine or a derivative thereof is contained as the complexing agent.

  On-vehicle electronic device
  Patent number: 9320161
  Abstract: A first drive arm and a second drive arm are rotatably coupled. A tip portion of the first drive arm and a device main body are connected to each other through a first connection link, and a tip portion of a second drive arm and the device main body are connected to each other through a second connection link. Because each of the drive arms and the device main body are connected to each other through an axial rotational portion, the device main body is moves smoothly between an extended position and a retracted position, and vibration and rattling are suppressed.
  Patent number: 9216701
  Abstract: A display device includes a display unit having a display screen on a front side, a driving mechanism configured to move the display unit, a holder configured to support the display unit and reciprocally move the display unit relative to the holder in a linear trajectory parallel to the display screen, a rotation guiding mechanism in the driving mechanism configured to rotate the holder, and a movement guiding mechanism in the driving mechanism configured to move the display unit relative to the holder after the holder is rotated to a predetermined position.
  In-vehicle display apparatus
  Patent number: 9036336
  Abstract: An in-vehicle display apparatus includes a display panel including a rectangular display screen; a pair of semicircular decorative rings (frames) obtained by dividing an annular member into two parts along a line extending in a lateral direction of the display screen; and a driving mechanism that drives the decorative rings to reciprocate toward and away from each other in a longitudinal direction of the display screen. The decorative rings are rotatable around axes extending in the lateral direction of the display screen. The driving mechanism moves the decorative rings while the decorative rings are in front of the display panel and in parallel positions in relation to the display screen. The decorative rings are rotated on sides of the display panel in a longitudinal direction of the display panel and stored in storage spaces.

  Abstract: A vehicle display apparatus includes a first partition member and a second partition member disposed in front of a display screen of a display panel. Each of the first and second partition members includes a window portion. The first and second partition members may be set in separated positions or in overlapping positions. In the separated positions, the first and second partition members are spaced apart from each other along the display screen. In the overlapping positions, the first partition member is separated forward from the display screen, the second partition member is located between the first partition member and the display screen, and the window portions of the first and second partition members overlap.
  Touch screen device
  Patent number: 9001065
  Abstract: A touch screen device includes a motor attached to a movable chassis to support the touch panel, a rotor fixed to the motor shaft, a driven rotor meshing with the rotor, a cam mechanism that converts the rotational driving force of the motor into a driving force in the thrust direction and transmits the driving force to the movable chassis, and a leaf spring elastically urging the touch panel moved by the cam mechanism toward the original position. The cam mechanism includes two wave cam portions that each have a cam surface having a series of wave-like recesses and protrusions arranged along a circumference and, and cam engaging portions that are provided at the axial ends of the rotors and that are in sliding contact with the cam surfaces.

  On-vehicle display apparatus
  Patent number: 8649161
  Abstract: An on-vehicle display apparatus includes a motor, a gear train, a threaded rod, a slider screwed to the threaded rod, and a display main body rotatably connected to the slider. The lead angle of the threaded rod is set greater than the friction angle thereof. The gear train includes first and second gears facing each other. Protrusions provided on one of the first and second gears are fitted in recesses provided in the other. A spring member elastically urges the first gear toward the second gear. A detection sensor detects the size of an external force on the basis of the displacement of the first gear against the spring member in the axial direction. The motor is controlled on the basis of the detection result of the detection sensor such that the display main body is moved away from the external force.
