  • Publication number: 20180313454
    Abstract: A check valve is provided with a rectilinear flow passage having a liquid inlet and a liquid outlet and allowing a liquid to flow therethrough in one direction, and a first valve body, a first valve seat, a second valve body, and a second valve seat are provided in the rectilinear flow passage. A first drive body is provided in the rectilinear flow passage at a position closer to the liquid inlet than the first valve body so as to be movable in one direction. The first drive body is driven in one direction by the drive mechanism. The drive mechanism is adapted to set the first drive body either to an open state in which the first drive body presses the first valve body toward the liquid outlet side to detach the first valve body from the first valve seat or to a closure state in which the first drive body does not press the first valve body toward the liquid outlet but allows the first valve body to be seated on the first valve seat.

  • Patent number: 10100403
    Abstract: A surface-coated cutting tool includes a base material and a coating formed on a surface of the base material. The coating includes a first hard coating layer including crystal grains having a sodium chloride-type crystal structure. The crystal grain has a layered structure in which a first layer composed of nitride or carbonitride of AlxTi1?x and a second layer composed of nitride or carbonitride of AlyTi1?y are stacked alternately into one or more layers. The first layer each has an atomic ratio x of Al varying in a range of 0.76 or more to less than 1. The second layer each has an atomic ratio y of Al varying in a range of 0.45 or more to less than 0.76. The largest value of difference between the atomic ratio x and the atomic ratio y is 0.05?x?y?0.5.
