  • Publication number: 20230343541
    Abstract: A photoelectric-surface electron source includes: a glass substrate that receives laser light from a substrate light-receiving surface including microlenses and that focuses the laser light toward a substrate main surface located on the opposite side from the substrate light-receiving surface; a photoelectric surface that is provided to the substrate main surface, and that receives the focused laser light and emits photoelectrons; and an extraction electrode that is fixed to the substrate main surface and that extracts the photoelectrons from the photoelectric surface. The extraction electrode is disposed away from the photoelectric surface along the normal direction of the substrate main surface and has: an electrode part in which electrode holes for allowing the photoelectrons to pass therethrough are provided; and a frame part that is fixed to a region surrounding the photoelectric surface in the substrate main surface.

  • Patent number: 9492338
    Abstract: A novel pressure-sensitive adhesive tape package easy to open and easy in application of an adhesive tape is disclosed. The pressure-sensitive adhesive tape package 10 according to the present invention includes an adhesive tape 14 that accommodates a support 18 and an adhesive agent layer 12 provided on one surface of the support 18, and a release sheet 16 releasably attached to the adhesive agent layer 12. Moreover, the release sheet 16 is folded with the adhesive tape 14, and the adhesive tape 14 is sealed inside of the folded release sheet 16. A plurality of temporary attach portions 50 to 54 spaced from each other is provided in a half of the adhesive agent layer 12 in the adhesive tape 14 to securely expose the half when the release sheet 16 is opened.

  • Patent number: 9318312
    Abstract: An ultraviolet light generating target 20 includes a substrate 21 made of sapphire, quartz, or rock crystal; and a light-emitting layer 22 that is provided on the substrate 21 and that generates ultraviolet light upon receiving an electron beam. The light-emitting layer 22 includes powdered or granular Pr:LuAG crystals. By using such a light-emitting layer 22 as the target, the ultraviolet light generating efficiency can be increased more remarkably than when a Pr:LuAG single crystal film is used.
