  • Publication number: 20190277375
    Abstract: A toroidal continuously variable transmission includes a preload spring disposed between a rotary assembly including a first disc and a pressing device, and a driving force transmission shaft, and a thrust bearing disposed between a first member and the preload spring, the first member being one of the rotary assembly and the driving force transmission shaft. In a direction of an axis line, a gap is formed between a second member and the thrust bearing, the second member being the other of the rotary assembly and the driving force transmission shaft. A dimension of the gap in the direction of the axis line is less than a deformation amount of the preload spring in the direction of the axis line, at an elastic limit.

  • Publication number: 20190265357
    Abstract: An electromagnetic wave from a transmitter (100) is emitted toward the outside of a first angular range (AR). A receiver (200) cannot detect an electromagnetic wave reflected at a position somewhat close to a sensor device (10), specifically, an electromagnetic wave reflected at a position apart from the sensor device (10) by less than a distance R1. Specifically, when the electromagnetic wave is reflected at the position apart from the sensor device (10) by less than the distance R1, the electromagnetic wave reaches the sensor device (10) before the first angular range (AR) reaches a Y axis. Consequently, the electromagnetic wave reflected at the position somewhat close to the sensor device (10) is not detected by the receiver (200).

  • Publication number: 20190204438
    Abstract: A measuring device (200) is a device disposed in a mobile body, and includes a measurement unit (202) that scans an object by emitting electromagnetic waves. The measurement unit (202) is controlled by a measurement unit control device (203) including a control unit (204). The control unit (204) sets a scanning range of the measurement unit (202) using information on a position that is a predetermined distance ahead. Specifically, the control unit (204) determines a position that is a predetermined distance ahead of the current position of the mobile body (240), on a predicted course of the mobile body (240). Further, the control unit (204) uses information on the position that is a predetermined distance ahead to set the scanning range of the measurement unit (202).

  • Patent number: 9076400
    Abstract: A memory-type liquid crystal display device includes transistors (N1, N2), retention electrodes (MRY), refresh output control sections (RS1), and capacitors (Cb1). In a data retention period, an electric potential of each of the retention electrodes (MRY) is changed via a corresponding one of the capacitors (Cb1) by changing an electric potential level of a retention capacitor wire signal that is supplied to a corresponding CS line (CSL(i)). Each of the refresh output control sections (RS1) receives the electric potential thus changed of a corresponding one of the retention electrodes (MRY) via the input section and controls an electric potential of a corresponding pixel electrode (PIX) in accordance with the electric potential thus changed.
