  • Patent number: 10352822
    Abstract: A temperature display device of a vehicle is provided, which includes a temperature sensor for detecting a temperature of coolant of an engine, the coolant being switched in circulation state by opening and closing a thermostat, between a first state where the coolant is circulated through a radiator and a second state where the coolant is circulated bypassing the radiator, a display unit for displaying a temperature of the coolant, and a controller for controlling a display mode of the display unit based on the detected temperature by the temperature sensor. When the detected temperature changes within a first temperature range where the thermostat is in an open state, the controller changes the displayed temperature on the display unit by less than the change of the detected temperature.

  • Patent number: 8016283
    Abstract: In a recording sheet feeder, a recording sheet tray moving mechanism moves a recording sheet tray between an upper position, at which an uppermost recording sheet of a plurality of recording sheets loaded on the recording sheet tray contacts a feed roller, and a lower position, at which the uppermost recording sheet separates from the feed roller. A first eccentric cam and a second eccentric cam rotate to press down the recording sheet tray. A driving force switch member drives the recording sheet tray moving mechanism when a driver rotates in a first direction, and rotates a feed roller driving shaft mounted with the feed roller when the driver rotates in a second direction.
