  • Patent number: 10859177
    Abstract: An electrically operated gas flow regulating valve causes a needle valve body to move axially by the rotation of an electric motor through a motion conversion mechanism. The mechanism includes: a rotating body rotated by the electric motor; a cylindrical cam body prevented from rotating; a cam pin which is engaged with a spiral cam groove formed in the cam body and which is fixed to the needle valve body.

  • Patent number: 10825628
    Abstract: An microelectromechanical switch uses electrostatic attraction to draw a beam toward a contact and electromagnetic repulsion to disengage and repel the beam from the contact. The electrostatic attraction is generated by a gate electrode. The electromagnetic repulsion is generated between the beam and a magnetic coil positioned on the same side of the beam as the contact. The magnetic coil produces a magnetic field, which induces a current in the beam that repels the magnetic coil. The gate electrode and the magnetic coil may be co-planar or in different planes. A circuit may also operate a coil-shaped structure act as the gate electrode and the magnetic coil, depending on the configuration.

    Abstract: A fuel injection control unit includes an injection amount detector and a correction unit. When implementing partial lift injection where a valve closing operation is started after the valve body starts a valve opening operation and before a valve body reaches a maximum valve open position, the injection amount detector detects a physical quantity (valve closing timing) having a correlation with an injection amount. When implementing the partial lift injection, the correction unit corrects an energization time of a fuel injection valve on the basis of a detection value (learning value) that was previously detected by the injection amount detector. An energization time in a small amount region longer than a predetermined time in the partial lift injection is allowed to be corrected on the basis of a value (small amount time detection value) detected in the small amount region by the injection amount detector.

A method for controlling a valve as mentioned above provides that, upon actuation of the electrodynamic actuator, during energization of the coil by a voltage source, a capacitor connected in parallel to the coil is charged. After termination of the energization by the voltage source, the coil is energized further by a discharge of the capacitor.

  • Patent number: 9797121
    Abstract: A system and method for unclogging a drain involving at least one internal member and at least one external member. At least one member is ferromagnetic, and at least one member is a magnet. External members may have handles. Internal members are disposed inside a pipe and external members are disposed outside a pipe. When an external member is moved, the magnetic force between the internal and external members causes the internal member to move. Internal members can be disposed such that they cause a clog to move further into the drain system. Internal members can also be disposed such that they are below the clog when it forms, allowing the internal members to move the clog out of the pipe system, into the sink, toilet, or other basin. Safety members can be disposed below the internal members to prevent loss of internal members into pipe system.

  • Patent number: 9567736
    Abstract: A shutoff valve connects between a toilet fill valve and a water supply line for a toilet tank. A housing containing a valve mechanism is positionable between open and closed positions. A latching mechanism holds the valve mechanism in the open position unless receiving an electric signal from an electronic sensing system upon detection of a fault condition. A manually-actuated reset lever returns the valve mechanism to the open position. The electronic sensing system includes at least one water level sensor for sensing a water level in the toilet tank, the electronic sensing system programmed to detect a slow flush valve leak, a stuck-open flush valve, or a high water level fault. Another water level sensor may be included in the toilet bowl to detect a plugged toilet fault condition.

  • Patent number: 9546743
    Abstract: A substantially leak-free, sealable microvalve that can be repeatedly opened and sealed is presented. The resealable microvalve includes a block with a through via and a sealing plate. The gap between the block and the sealing plate is sealed by a sealing material. The sealing material can be melted when heat is applied and can be solidified when heat is absent. To close the resealable microvalve, heat is applied by flowing a current through a resistive heater and an actuator brings the block and the sealing plate into a contacting position. By removing the heat, the sealing material is solidified and creates a sealed state. To open the resealable microvalve, heat is applied to the sealing material. When the sealing material melts, the actuator moves the block and the sealing plate into a spaced apart position.

  • Patent number: 9236740
    Abstract: An apparatus for removing harmonic noise from a power transmission line transmitting electricity at a primary frequency includes a filter and a controller coupled to the sensor and to an actuator-generator. The filter separates electricity at a harmonic of a primary frequency from the electrical signal transmitted by the power transmission line. The controller is configured to modulate consumption of electricity from the power transmission line. The consumption is controlled by electrical actuation of the actuator-generator, such that the electrical actuation of the actuator-generator causes consumption of electricity from the power transmission line at a harmonic of the primary frequency. The actuator-generator is coupled to an elastically deformable component, such that electrical actuation of the actuator-generator generates tension in the elastically deformable component.
