  • Patent number: 11353894
    Abstract: A liquid processing apparatus includes: a substrate processing unit; a supply line that supplies the fluid to the substrate processing unit; a flow meter that measures a flow rate of the fluid flowing through the supply line; a flow rate adjustment mechanism that adjusts the flow rate of the fluid flowing through the supply line; and a controller that control the flow rate adjustment mechanism based on a measurement result of the flow meter. The controller receives the measurement result at a first cycle. When the measurement result of the flow meter indicates that the flow rate of the fluid flowing through the supply line is included in a preset range, the controller causes the flow rate adjustment mechanism to adjust the flow rate of the fluid flowing through the supply line at a cycle having a time interval longer than a time interval of the first cycle.

  • Patent number: 10739021
    Abstract: An air handler unit (AHU) in communication with a building automation system (BAS) or through direct programming of one or more smart valves within the AHU operates to meter an amount of water that flows through a coil in the AHU. In one embodiment, the BAS transmits a temperature setpoint signal to the smart valve and allows the smart valve to control its valve position without additional input from the BAS. In another embodiment, the AHU includes a master smart valve and a second valve. The BAS provides the temperature setpoint signal to the master smart valve, which in turn provides another temperature setpoint signal to the second valve. The second valve may take the form of a slave smart valve or a slave non-smart valve.

  • Patent number: 10684632
    Abstract: A pressure control device controls a flow rate of gas supplied to a pressure control target to maintain an inside of the pressure control target at set pressure. The pressure control device includes a controller that is configured to: subtract, at a predetermined ratio, a signal related to the supply of gas from a set pressure signal indicating the set pressure, when gas is being supplied into the pressure control target in order to bring the inside of the pressure control target to the set pressure; compare a detected pressure signal indicating pressure within the pressure control target with the set pressure signal subjected to the subtraction; and control, on the basis of a comparison result obtained by the controller, a flow rate control valve which controls a flow rate of gas supplied to the pressure control target.

  • Patent number: 10677373
    Abstract: The disclosure discloses a servo-valve that controls a fluid discharged from a discharge port of a nozzle by displacing the nozzle and drives an actuator. The servo-valve includes a receiver that includes an inflow surface provided with a first inflow port and a second inflow port into which the fluid discharged from the discharge port flows. The nozzle includes a force generation portion that includes an end surface provided with the discharge port and an outer circumferential surface formed in the periphery of the end surface. When the nozzle is displaced from a neutral position toward the first inflow port, the fluid inside the second inflow port is blown out toward the nozzle. The force generation portion collides with the fluid blown out from the second inflow port and causes an assisting force in a direction matching a nozzle displacement direction toward the first inflow port. The nozzle easily moves by the assisting force generated in the force generation portion and thus a response speed is improved.

    Abstract: A gas pressure within a treatment chamber 2 can be more accurately regulated to a predicted target pressure whereby there can be provided a pressure control apparatus which can easily and speedily regulate the gas pressure for various combination of the treatment chamber 2, a sanction chamber 3 and a valve 4. A required inflow rate (Qi) at which it is necessary for gas to flow into the treatment chamber 2 in order to reach a preset target pressure (Psp) within the treatment chamber is calculated on the basis of the expression of Qi=Qo+(P/?t)V and the thus calculated required inflow rate (Qi) is flown into the treatment chamber 2 to control the pressure within the treatment chamber 2 to the required pressure (Psp).

  • Patent number: 10564653
    Abstract: Methods, systems, and computer-readable storage media for controlling and monitoring an electro-mechanical flushing mechanism in a pressurized water distribution system. A first pressure reading of water in a supply channel is taken, the supply channel being in fluid communication with a distribution line of the water distribution system and terminated by a flushing valve. The flushing valve is then actuated causing the valve to change state. A second pressure reading is taken of the water in the supply channel and a difference between the first and second pressure readings is computed. The computed difference is compared to a minimum pressure differential value, and, upon determining that the difference is not greater than the minimum pressure differential value, a central control system of the water distribution system is alerted that a valve failure has occurred.

  • Patent number: 10526195
    Abstract: In an example, a method of supplying fuel to a fuel tank of a vehicle includes supplying, via a fuel line, fuel to a fuel tank of a vehicle at an initial rate of fuel flow. The act of supplying the fuel causes an electrostatic charge to accumulate on a surface of the fuel in the fuel tank. The method also includes determining a level of ionization of an air medium in the fuel tank, and determining an increased rate of fuel flow based on a difference between the determined level of ionization and a baseline level of ionization. The electrostatic charge accumulated on the surface of the fuel dissipates at an increased rate when the determined level of ionization of the air medium is higher than the baseline level of ionization. The method further includes supplying the fuel to the fuel tank at the increased rate of fuel flow.
