  • Patent number: 10773613
    Abstract: In a vehicle seat, a second parallel link mechanism is actuated in order to adjust an vertical position of a seat body with respect to a vehicle body, such that a first parallel link mechanism is moved up or down together with the seat body with respect to the vehicle body. In order to recline a seatback as an integral unit with a seat cushion, the first parallel link mechanism and the second parallel link mechanism are actuated such that an upper link is maintained in a predetermined orientation. The upper link is restricted from rotating relative to the armrest, and so the armrest is also maintained in a predetermined orientation.

  • Publication number: 20200209033
    Abstract: To provide an MFC capable of improving an S/N ratio of a sensor signal even when a pressure difference between both sides of the MFC is small and a flow rate in the sensor flow path is low. Provided is a mass flow controller including a fluid flow path that allows a fluid to pass therethrough, a plurality of flow sensor units that measure a mass flow rate of the fluid passing through the fluid, an adjusting valve that adjusts a flow rate of the fluid passing through the fluid flow path, and a control unit that controls a degree of open of the adjusting valve. The flow sensor units are each a thermal flow sensor unit.
