    Abstract: A digital filter is configured to convert, into a digital value, the duty ratio of a control signal subjected to pulse width modulation according to a target toque to be set for a fan motor to be driven. A sampling circuit is configured to perform sampling of the output value of the digital filter at a sampling timing that is asynchronous with respect to the cycle of the control signal, so as to generate a torque instruction value. A driving circuit is configured to drive the fan motor according to the torque instruction value thus generated.

  • Publication number: 20150118065
    Abstract: According to one embodiment, a pump unit provided for piping which feeds a liquid at a preset unit flow rate includes (n+1) pumps and a constant flow valve. The (n+1) pumps are arranged in series and set to pressurize the liquid so as to achieve the unit flow rate when n pumps are arranged in series. The constant flow valve is installed downstream of the (n+1) pumps. The constant flow valve feeds the fluid at the unit flow rate by giving first resistance to the fluid when the fluid is pressurized by n pumps of the (n+1) pumps. The constant flow valve feeds the fluid at the unit flow rate by giving second resistance larger than the first resistance to the fluid when the fluid is pressurized by the (n+1) pumps.

  • Publication number: 20150086387
    Abstract: A method for warming up a vacuum pump arrangement having a booster pump and a backing pump downstream of the booster pump for evacuating a process chamber includes setting the booster pump at a first speed higher than an idle speed of the booster pump when the same is in an idle mode; and controlling a backing pressure at an outlet of the booster pump within a range from 0.1 mbar to 10 mbar at least for a period of time from when the vacuum pump arrangement is activated from the idle mode to when the booster pump reaches a temperature equal to or exceeding a first predetermined threshold value. Such method is implemented in system where a controlled is configured to carry out the above-motioned actions.

  • Patent number: 8956125
    Abstract: The present invention relates to a method for determining a flow rate indicator relating to the output flow rate of one or more activated pumps of a pumping station. The pumping station includes a well to be at least partially emptied by the pumps and an inlet through which inflow can be supplied into the well. The method includes the step of determining, using a computational device, an operating condition relating to the activated pumps. The pumps are temporarily deactivated and an inflow rate indicator relating to the inflow is determined using the computational device, responsive to the determination of the operating condition. The method further includes the step of determining, using the computational device, the flow rate indicator using the determined inflow rate indicator. The present invention is equally applicable to a well to be at least partially filled by the pumps.

  • Patent number: 8939730
    Abstract: A fan control system includes first and second fan control units. Each fan control unit includes a connector, a delay circuit, a switch unit, and a control circuit. Each connector is connected to a corresponding fan interface to receive a voltage signal. The delay circuit of the first fan control unit delays the voltage signal for a first period of time, and turns on the corresponding switch unit after the first period of time. The delay circuit of the second fan control unit delays the voltage signal for a second period of time, and turns on the corresponding switch unit after the second period of time. Each control circuit receives the corresponding delayed voltage signal, to start the corresponding fan. The first period of time is unequal to the second period of time.
