  • Publication number: 20220146866
    Abstract: An optical isolator includes a Faraday rotator including a trivalent ion exchange TAG (terbium-aluminum garnet), and arranged around the Faraday rotator, a central hollow magnet and a first and a second hollow magnet units arranged to sandwich the central hollow magnet in an optical axis direction. A magnetic flux density B [T] in the Faraday rotator and an optical path length L [mm] where the Faraday rotator is arranged satisfy 0<B??(1) and 14.0?L?24.0??(2). The optical isolator, compared with a conventional Faraday rotator such as a terbium-gallium garnet (TGG) crystal, contributes to reduction of a thermal lensing effect, being a pending problem, in a high-output fiber laser.

  • Publication number: 20190345067
    Abstract: A method includes molding a raw material powder containing a ceramic powder and a thermoplastic resin having a glass transition temperature higher than room temperature into a shape by isostatic pressing and in which a raw material powder slurry is prepared by adding the ceramic powder and the thermoplastic resin to a solvent so that the thermoplastic resin is 2% by weight or more and 40% by weight or less with respect to a total weight of the ceramic powder and the thermoplastic resin, a cast-molded body is to formed by wet-casting the raw material powder slurry into a shape, dried, and subjected to first-stage isostatic press molding at a temperature lower than the glass transition temperature of the thermoplastic resin, then this first-stage press-molded body is heated to the glass transition temperature of the thermoplastic resin or above, and warm isostatic press (WIP) molding is performed.

  • Publication number: 20190250810
    Abstract: An image processing apparatus includes: a display part that causes a touch panel display to display a first screen and a second screen adjacent to each other, the second screen being provided with a first area which is responsive to a slide operation performed by a pointer being slid in a direction of the first screen and a second area which is not responsive to the slide operation; a determiner that determines that the slide operation has been performed not on the first screen but in the first area in a case where the slide operation has been performed from the first area to the first screen; and a processor that performs a process based on a result of determination by the determiner.
