  • Patent number: 10948099
    Abstract: A motor operated valve includes a feed screw mechanism and a stopper mechanism. The feed screw mechanism includes a guiding part including an external thread portion on an outer surface thereof, and a guided part that is a cylindrical member constituting a rotation shaft of a rotor, and including an internal thread portion, which is engaged with the external thread portion, on an inner surface thereof. The stopper mechanism includes a stopper portion provided on the guided part, and a stopping face formed integrally with the guiding part. When a valve element is driven by the motor to move in a valve closing direction, the stopping face stops the stopper portion to restrict the movement of the rotor in the valve closing direction.

  • Patent number: 10937564
    Abstract: An electric wire for improving the adhesion force between the adjacent winding wires of a coil is described. The electric wire of the present invention may include a conductive wire with a substantially quadrilateral cross-sectional shape. The electric wire further includes a first groove and a second groove positioned diagonally at two opposite corners of the quadrilateral along a longitudinal direction of the conductive wire. An adhesive pocket filled with an adhesive is sized to fit within each of the first and second grooves at diagonally arranged opposite corners.

  • Patent number: 9874808
    Abstract: The present invention provides a mask blank used to produce a halftone phase shift mask to which ArF excimer laser exposure light is to be applied. The present invention attains the object by providing the mask blank comprising a transparent substrate, and a light semitransmissive layer formed on the transparent substrate and made only of Si and N or a light semitransmissive layer formed on the transparent substrate and made only of Si, N and O, wherein the light semitransmissive layer has an extinction coefficient of 0.2 to 0.45 at a wavelength of ArF excimer laser exposure light, a refractive index of 2.3 to 2.7 at the wavelength of ArF excimer laser exposure light, and a transmittance of 15 to 38% at the wavelength of ArF excimer laser exposure light, and further has a layer thickness of 57 to 67 nm.
