An electric pump includes a transmission unit that transmits rotational drive of a motor unit, a pump unit, and a rotary valve unit. The pump unit expands and contracts a pump chamber to draw in a fluid from an inlet and discharge the fluid from an outlet. The rotary valve unit includes a valve body and a valve cover. The valve body is rotated by the rotational drive force transmitted by the transmission unit. The valve cover includes a valve-side inlet that draws in a fluid and a plurality of fluid outlets that discharges the fluid to the exterior. The rotary valve unit is configured to switch the fluid outlets that come into communication with the inlet in accordance with rotational drive of the valve body. The valve body is intermittently driven by an intermittent drive mechanism that converts continuous drive corresponding to the rotational drive force into intermittent drive.

Electric pump

A vehicle seat includes a bladder as an actuator; a pump that is operated to supply air to the bladder; a switch that is operated to operate the pump; and a switching valve that is disposed in an air supply/discharge passage for the air for the bladder, the switching valve being configured to connect the air supply/discharge passage to a discharge port of the pump when the air is supplied to the bladder, and to connect the air supply/discharge passage to an exhaust port when the air is discharged from the bladder. The switching valve is incorporated in the switch, and is configured to receive an operating force applied to the switch, and to supply and discharge the air to and from the bladder in accordance with an operation of the switch.

Vehicle seat

A buckle pivotally arranged in a movable clamp of a first tube holder is attached with play to a buckle pivotally arranged in a movable clamp of a second tube holder When tubes are held in the first and second tube holders and release of the tubes from the holders and is prevented by a movement of a plunger in correspondence of excitation and demagnetization of a solenoid for a predetermined period of operation of the apparatus after holding the tubes (i.e., for a period required from the locking of the buckle until the completion of moving-down of a wafer holder).

Tube connecting apparatus

A buckle pivotally arranged in a movable clamp of a first tube holder is attached with play to a buckle pivotally arranged in a movable clamp of a second tube holder . When tubes are held in the first and second tube holders and , release of the tubes from the holders and is prevented by a movement of a plunger in correspondence of excitation and demagnetization of a solenoid for a predetermined period of operation of the apparatus after holding the tubes (i.e., for a period required from the locking of the buckle until the completion of moving-down of a wafer holder).

A tube connecting apparatus is arranged to hold tubes in a first tube holder and a second tube holder, to rotate a pair of rotatable clamping members which include separable pieces disposed in rotational symmetry for holding the tubes in either or both of the first tube holder and the second tube holder, to heat and melt the tubes by a heated cutting plate moving therebetween to cut the tubes, and to weld cut end faces of the different tubes. When the pair of clamping members are in a state of not holding the tubes rotation preventing members fixedly lock the clamping members in a predetermined position, preventing the clamping member from being rotated.
