  • Patent number: 11559116
    Abstract: A slider includes a slider body part that includes an upper wing plate and a lower wing plate, a stop tab body, a tab elastic member that biases the stop tab body, a base part integrally formed with the upper wing plate, and an operation cover part rotatably attached to the base part. The operation cover part includes a pressing projecting part that projects from an inner surface of a top plate part, and the pressing projecting part has a configuration in which by rotating the operation cover part, a locked state and an unlocked state can be switched therebetween. Accordingly, since a stop mechanism by the rotation of the operation cover part can be provided in the slider with a relatively simple configuration, the manufacturing cost can be reduced and the productivity can be improved.

  • Publication number: 20180058978
    Abstract: A lensmeter includes a light emission portion, a light reception portion, a storage unit, a display unit and a display control unit. The light emission portion emits light so as to radiate the light onto a lens-to-be-inspected. The light reception portion receives the light transmitted through the lens-to-be-inspected to measure an optical characteristic of the lens-to-be-inspected. The storage unit stores a measured value of the optical characteristic of the lens-to-be-inspected. The display unit displays the measured value of the optical characteristic of the lens-to-be-inspected stored in the storage unit. The display control unit causes the display unit to display a target pattern including at least two different colors, and changes the target pattern in accordance with the measured value stored in the storage unit.

  • Patent number: 9831067
    Abstract: In a film-forming apparatus according to an aspect, a substrate placed on a substrate placing region passes through a first region and a second region in this order by rotation of a placing table. A precursor gas is supplied to the first region. Plasma of a reaction gas is generated in the second region by a plasma generation section. The plasma generation section includes an antenna that supplies microwaves as a plasma source. The antenna includes a dielectric window member and a waveguide. The window member is provided above the second region. The waveguide defines a waveguide path that extends in a radial direction. The waveguide is formed with a plurality of slot holes that allow the microwaves to pass therethrough from the waveguide path toward the window member plate. A bottom surface of the window member defines a groove that extends in the radial direction.
