  • Patent number: 11143182
    Abstract: An oil pump fixation detecting apparatus includes an oil pump, a discharge state switching unit, a target oil pressure setting unit, a pressure regulator, and a fixation determining unit. The discharge state switching unit performs control of switching a discharge state of the oil pump from a full-discharge state to a partial-discharge state. The fixation determining unit determines that the oil pump is not fixed in the full-discharge state in a case where oil pressure in a high-pressure oil passage has dropped by a predetermined value or more within a predetermined time, and determines that the oil pump is fixed in the full-discharge state in a case where the oil pressure in the high-pressure oil passage does not drop by the predetermined value or more.

  • Patent number: 10962112
    Abstract: A transmission apparatus includes a planetary gear mechanism, a first path, a second path, and a continuously variable transmission. The planetary gear mechanism has a first gear, a second gear, and a third gear. The first path is configured to transmit power from an output shaft of an engine to the first gear. The second path is configured to transmit the power from the output shaft to the second gear. The continuously variable transmission is disposed in the first path.

  • Publication number: 20180012332
    Abstract: A method for preventing burn-in conditions on a display of an electronic device is disclosed. The electronic device acquires a position of, for example, a task bar being displayed on an OELD screen, extracts a color of a pixel located adjacent to the task bar, and generates an overlay window of a color based on the extracted color. The color of the overlay window is translucent and continuously changes from the extracted color to black with an increase of the distance from the pixel located adjacent to the task bar. The task bar is displayed on the OELD screen with the overlay window overlaying the task bar.
