  • Patent number: 11025178
    Abstract: An actuator device includes an actuator member, a drive subject, a drive device, and a tension applicator. The actuator member is configured to be deformed in response to application of energy to the actuator member from an outside of the actuator member. The drive subject is coupled to the actuator member. The drive device is configured to apply the energy to the actuator member and thereby displace the drive subject in a deforming direction of the actuator member. The tension applicator is configured to apply the actuator member a tension, which enables correction of a tension change generated by at least one of elongation and contraction of the actuator member that is induced by natural deformation of the actuator member.

  • Patent number: 7779867
    Abstract: The present invention relates to a miniature valve, which includes a valve body comprising an inflow channel, an outflow channel and a liquid chamber, and a close assembly comprising a driver, a rocker and a valve film. The close assembly connects to the valve body and is configured to selectively close the inflow channel and the outflow channel. The rocker can be driven by the driver to move, so that the movement thereof acts on the valve film and makes the valve film selectively close the channel. The rocker and the valve film are separate components. The valve film, an elastic film locating in the liquid chamber, has a size configured to cover the inflow channel and the outflow channel. The miniature valve according to the present invention doesn't have interior dead area and has a slight effect on liquid fluctuation when switching channels.

  • Patent number: 7534074
    Abstract: In order to prevent the contamination of particulates such as food material particulates, facilitate maintenance, and to enhance the process sealing accuracy, a flow path switchover device is presented. The device of the present invention has a tube assembly including first and second main tube members and a branch member. The first and second main tube members are interconnected via a first ring member. The first main tube member and the branch member are interconnected via a second ring member arranged at a preset angle with the first ring member. A metal changeover damper supported on a rotating shaft swings between the first and second ring members and accordingly blocks and seals either the connection between the first main tube member and the second main tube member or the connection between the first main tube member and the branch tube member, while allowing the other connection.

  • Patent number: 7290566
    Abstract: A diverter valve for bulk solids is disclosed. The valve has a single inlet and two or more outlets, preferable three. Two pivotal gate valves are used for three outlets so that one is open and two are closed. The valve includes a novel pivotal gate structure which includes a resilient planar component sandwiched between two rigid planar components. The resilient component engages the valve housing so as to avoid metal to metal contact. The invention also includes a seal bar on each side of the housing which presents a linear surface that is perpendicular to the plane of the gate structure so as to present a firm surface against which the gate structure seals. The seal bars for each gate structure are discontinuous so as to accommodate positioning of the other gate structure in a smooth non-deformed sealing relationship to the housing. Additional seal bars engage the top and sides of each gate structure when moved to a “closed” position.

  • Patent number: 7273071
    Abstract: A control for controlling the amount of heated fluid entering the inlet of the driving heat source for a refrigerant absorption cycle is controlled to vary the relative amount of heated fluid entering the driving heat source inlet, and being dumped to atmosphere. Preferably, a diverter valve is utilized such that a first valve body (40) communicates the flow into the driving heat source inlet, and moves in opposition to a second valve body (46) controlling the flow through the exhaust. The two valves bodies (40, 46) are preferably mechanically linked. Since the heated fluid is not allowed to enter the refrigerant absorption cycle as its drive heating source, no additional hardware and control for dumping excess heat is necessary within the refrigerant absorption cycle. A computer control preferably drives the first valve to a precise position and the linkage ensures the second valve is also received at a precise position.
