  • Patent number: 12165827
    Abstract: An X-ray generation device includes: an electron gun that emits an electron beam; a target portion in which a plurality of elongated targets that generate an X-ray because of incidence of the electron beam are disposed parallel to each other; a housing that accommodates the electron gun and the target portion; and an X-ray emission window provided in the housing to emit the X-ray generated in the target portion, to an outside of the housing. The targets are disposed on the target portion to face the electron gun at a predetermined inclination angle with respect to an emission axis of the electron beam. The X-ray emission window is disposed at a position where the X-ray generated in a direction perpendicular to the target portion is transmittable through the X-ray emission window, to face the target portion at a predetermined inclination angle.

  • Publication number: 20240332247
    Abstract: A method of manufacturing a light emitting device includes preparing a plurality of first elements including first bonding parts and a wiring substrate including a plurality of second bonding parts. The method further includes placing the first elements on the wiring substrate by bonding the first bonding parts and the second bonding parts under first bonding conditions, and bonding the first bonding parts and the second bonding parts under second bonding conditions by placing a buffer sheet on the first elements and applying pressure on the first elements via the buffer sheet towards the wiring substrate. The bonding conducted under the second bonding conditions is performed multiple times.

  • Patent number: 11372138
    Abstract: An anti-reflection film (X) of the present invention includes a laminated structure including a substrate (11), a hard coat layer (12), and an anti-reflection layer (13), and a luminous reflectance of the anti-reflection layer (13) side is 2% or less. The anti-reflection layer (13) includes a surface (13a) having a coefficient of kinetic friction of 0.3 or less and a coefficient of static friction of 0.3 or less. In addition, in the anti-reflection film (X), after a rubbing test performed on the surface (13a) using steel wool #0000 as a rubbing material under conditions of a load of 200 g/cm2, a rubbing stroke length of 10 cm, and reciprocations of 1000 times, a difference of the haze value (%) after the rubbing test from the haze value (%) before the rubbing test is 0.1 or less. Such an anti-reflection film is suitable for achieving high scratch resistance together with high anti-reflective properties.
