  • Patent number: 10450253
    Abstract: A simple production process is provided of a perfluoroalkyl compound that uses monohydroperfluoroalkane as a starting material, the perfluoroalkyl compound being an important intermediate of organic electronic materials, medicine, agricultural chemicals, functional polymer materials and the like. With monohydroperfluoroalkane is reacted a base and then a carbonyl compound to produce an alcohol having a perfluoroalkyl group. For example, potassium hydroxide is made to interact with trifluoromethane, and a reaction with a carbonyl compound is induced to produce an alcohol having a trifluoromethyl group.

  • Patent number: 10400723
    Abstract: A first spring axially urges a needle valve toward an injection hole. A second spring axially urges a movable core toward a stationary core with an urging force that is smaller than an urging force of the first spring. A stopper is placed on one axial side of the movable core where the injection hole is located. The stopper limits movement of the movable core toward the injection hole to limit an amount of compression of the second spring.

  • Patent number: 9951867
    Abstract: A piston damper has a cylinder including an attachment portion; a piston reciprocatingly disposed inside the cylinder; and a rod including an attachment portion that is moved synchronously with the piston. Each of the attachment portions of the cylinder and the rod is adapted to connect to different one of a first member and a second member to damp a movement of the other member relative to one member among both the members. At least one of the attachment portion of the cylinder and the attachment portion of the rod is formed with a fitting hole, and the attachment portion is axially supported in a fitted state between the fitting hole and an axis relative to at least one of the first member and the second member, and includes an urging device absorbing looseness of the fitting hole relative to the axis.

  • Patent number: 9366996
    Abstract: A sealing structure includes a housing to accommodate powder, a powder roller having a surface to bear and convey the powder, and an entrance seal disposed between the powder roller and the housing to allow powder remaining on a circumferential surface of the powder roller to enter the housing. A pair of left and right edge seals is provided in a circumferential direction of the powder roller to overlap with outer circumferential surfaces of both ends of the entrance seal, respectively. Both ends of the entrance seal include powder damming sections extended from both ends thereof along the pair of left and right edge seals, respectively. A pair of inner edges of the respective powder damming sections is each sandwiched between a corresponding one of the pair of left and right edge seals and the powder roller while substantially symmetrically inclining from the rotation direction of the powder roller.

  • Patent number: 9285010
    Abstract: A damper device includes a protruding portion located outside a closing portion of a cylinder body facing a piston body and forming a flow path communicating inside and outside of the cylinder body; a plug body including a shaft portion inserted into the flow path from an outside of the cylinder body; and an urging device of the plug body. An insertion length of the shaft portion of the plug-like body into the flow path against urging of the urging device increases by change in pressure due to a movement or a relative movement of the piston body in a direction separating from the closing portion of the cylinder body.

  • Patent number: 8827056
    Abstract: A cylinder body is partitioned by a partition into a first chamber that is divided from an outside by a cap body and a second chamber accommodating a piston body. A flow channel communicating the first chamber and the second chamber with each other is formed in the partition, and a shaft is projected from the partition onto the first chamber side. The cap body includes a through-hole, the shaft is inserted movably in the through-hole from a reference position along an axis line direction of the cylinder body. There is provided a throttle structure that changes a gap between the through-hole and the shaft when the cap body moves from the reference position by a pressure change generated by a movement or a relative movement of the piston body.

  • Patent number: 8307505
    Abstract: A rotation control device is configured so that a spring force of a torsion coil spring holds an attitude of a rotation body at a pre-advancement position corresponding to a post-return position (a), and a post-advancement position corresponding to a pre-return position (b), respectively. The rotation control device includes a first rotation part supporting one end of the torsion coil spring and supported on a fixed body so as to rotate as the rotation body rotates, and a second rotation part rotatably supported on the fixed body at a first rotation part side and supporting the other end of the torsion coil spring. When the first rotation part rotates, the second rotation part rotates together with the first rotation part. A wound portion of the torsion coil spring is most elastically deformed when the rotation body is at an intermediate position (c) between the position (a) and the position (b).
