  • Patent number: 11938783
    Abstract: A refrigeration cycle device including a first pressure reducing valve, a first evaporator that exchanges heat between the refrigerant decompressed in the first pressure reducing valve and air, a second pressure reducing valve that is disposed in parallel with the first pressure reducing valve; a second evaporator in which the refrigerant decompressed in the second pressure reducing valve to absorbs heat from a battery; a third pressure reducing valve that reduces the pressure of the refrigerant evaporated in the second evaporator; and a controller configured to control opening degrees of the second pressure reducing valve and the third pressure reducing valve. The controller performs a limit control for controlling the opening degree of the second pressure reducing valve to an opening degree of smaller one of a battery cooling opening degree and an air cooling opening degree.

  • Publication number: 20240059262
    Abstract: A pedal pad in an organ-type pedal device swings about a predetermined axis when stepped on by a driver's foot. A sensor unit outputs a signal corresponding to a swing angle of the pedal pad. A reaction force generation mechanism generates a reaction force against a driver's stepping force applied to the pedal pad. A first housing holds or covers at least one of a rotation shaft provided at the axis of the swinging of the pedal pad, the sensor unit, and the reaction force generation mechanism. A second housing is made of a rigid portion having a Young's modulus greater than that of the first housing or has the rigid portion at least in part. The second housing is configured to support a portion of the reaction force generation mechanism on one side opposite to the pedal pad by the rigid portion.

A sensor unit outputs a signal corresponding to a swing angle of the pedal pad. A reaction force generation mechanism has an elastic member that generates a reaction force against a driver's pedaling force applied to the pedal pad. A first housing covers the reaction force generation mechanism, and an opening at least on one side. A second housing is provided on one side of the first housing in a swing direction of the pedal pad. Further, the first housing has a largest opening on a second housing side, which is closed by the second housing and into which the elastic member of the reaction force generation mechanism in a non-bending state is insertable.

  • Publication number: 20220198303
    Abstract: Provided is an environmental factor prediction device that includes a predictor and predicting means. The predictor uses, as explanatory variables: water quality data in a plurality of layers in water, the data including a value corresponding to a biochrome level or a bioluminescence level (e.g. chlorophyll concentration), water temperature, salt concentration, dissolved oxygen, turbidity and flow rate; and meteorological data including atmospheric temperature, precipitation and sunshine duration, and outputs an estimated value of each item of the explanatory variables at a unit time later, based on time series data of the explanatory variables. The predicting means predicts the water quality data up to an N unit time later by repeating prediction using the estimated value acquired by the predictor as input of the predictor again.
