Abstract: In a snow accretion test method, a snow accumulation step of accumulating snow on a specimen, and a snow accretion step of freezing snow accumulated on the specimen in a state where snow is not supplied to the specimen are performed. The snow accumulation step and the snow accretion step are repeatedly performed. In the snow accretion step, the ambient temperature of the specimen is adjusted to a temperature lower than the ambient temperature in the snow accumulation step.

Abstract: A snow environment test apparatus includes an injector including a two-fluid nozzle, a temperature setting section for setting an indoor temperature, an air conditioner for cooling an inside of a test chamber, a temperature control section for controlling the air conditioner, a water flow rate setting section for setting a flow rate of water to be supplied to the injector, a water supply section for supplying water having a predetermined temperature to the injector, a snow quality selection section for selecting snow quality, a related information storage section that stores information in which a temperature in the test chamber, a flow rate of water to be supplied to the injector, a pressure of air to be supplied to the injector, and a snow quality are related with each other, and a pressure regulation section for regulating the pressure of the air to be supplied to the injector to a pressure obtained by using the information stored in the related information storage section.

Abstract: A snow environment test apparatus includes a first nozzle that injects water particles, a second nozzle that injects water particles smaller in size than the water particles from the first nozzle, an air conditioner that regulates a temperature in a test chamber to a set temperature, a state selection section that sets a state of snow to be caused to fall, and a flow rate regulation valve that regulates a ratio between quantities of water to be supplied to the first nozzle and to the second nozzle for obtaining the state of the snow set by the state selection section at the set temperature as a temperature at which a snow environment is obtained.

Abstract: There is provided an environmental test apparatus that can create a predetermined environment inside a test chamber, the environmental test apparatus including: the test chamber for placing a test target object; a heating portion; and a cooling portion. The cooling portion has a refrigeration circuit having a compressor, a condenser, an expansion portion, and an evaporator and in which a phase-changing refrigerant is to be circulated. The refrigeration circuit has a first bypass flow path connecting a discharge side of the condenser and a suction side of the compressor and the first bypass flow path is provided with a first flow rate control portion. A temperature measurement portion for measuring a temperature of the compressor and a controller are provided. The controller is configured to control a substantial degree of opening of the first flow rate control portion according to a detection value of the temperature measurement portion.

Abstract: A shift device comprises a shift body, a click mechanism and a guide portion. The shift body is moved to change a shift position of the shift body. The click mechanism has a click member and a click surface against which the click member is biased to abut. The click mechanism is configured so that, when the shift body is movably operated, one of the click member or the click surface moves in accompaniment with movement of the shift body and imparts a clicking feel to the shift body. The guide portion guides the click member to the click surface and is disposed in a position in which it does not oppose the click surface.

Abstract: A shift device including: a shift body that, when operated, is configured to change a shift position; a first switch that, when operated, is configured to control a drivetrain system of a vehicle; and a second switch that, when operated, is configured to control a non-drivetrain system of a vehicle, the second switch having a different operating aspect from the first switch.

Abstract: According to one embodiment, a vehicle-seat slide device includes a rail to be fixed to a floor, the rail extending in a vehicle front-back direction; a slider slidably attached to the rail and fixed to a seat; a lock member being movable between a lock position at which the slider is locked to one of slide positions on the rail and a lock release position at which the slider is released from being locked to the rail; a support member fixed to the slider; and an operational member supported by the support member to be rotatable about a rotational center extending in a vehicle lateral direction. The operational member receives an input from an input member to rotate in a first rotational direction around the rotational center to thereby move the lock member from the lock position to the lock release position.
