Abstract: An electronic component package includes a base, a lid, and a bonding layer part. The lid has a first recess. The lid is bonded to the base with a bonding layer part interposed therebetween. The base closes the first recess of the lid. The base and the lid define an internal space of the electronic component package. An electronic component is located in the internal space of the electronic component package. The electronic component is mounted on the base.

Abstract: A solid-state battery package that includes: a substrate; a solid-state battery on the substrate; and a water vapor barrier layer between the substrate and the solid-state battery. The water vapor barrier layer preferably has both an Si—O bond and an Si—N bond, and preferably has a water vapor transmission rate of less than 5×10?3 g/(m2·Day).

Abstract: A vapor chamber that includes a housing defining an internal space, and a working medium and a wick structure in the internal space of the housing. As viewed in a plan view, the vapor chamber has a first region with a first thickness and a second region with a second thickness, the second thickness being smaller than the first thickness.

Abstract: A vapor chamber that includes a housing; a pillar arranged in the housing; a working fluid sealed in the housing; and a wick arranged in the housing. The pillar has a first bottom surface and a second bottom surface, and pores therein. The first bottom surface is in contact with a first main interior surface of the housing and the second bottom surface is in contact with the wick. The first bottom surface has an area larger than an area of the second bottom surface. The pillar has a side surface connecting a periphery of the first bottom surface and a periphery of the second bottom surface. A cross-sectional area of the pillar decreases along a direction from the first bottom surface to the second bottom surface.

Abstract: A vapor chamber that includes a housing, a wick structure joined to a major inside surface of the housing, and a working liquid enclosed inside the housing. The wick structure is joined to the housing at a joint portion within a joint region, and a proportion of a total area of the joint portion within the joint region to an area of the joint region is 50% or less.

Abstract: A vapor chamber includes a housing including first and second sheets that face each other and that include respective outer edge portions joined to each other, supports that support the first and second sheets from inside and that are disposed therebetween, and a hydraulic fluid enclosed in the housing. The first and second sheets do not include an angled portion having an angle of about 90° or less between a joint and a support nearest to the joint. The expression 0.02?b/a?0.3 is satisfied, where a is a distance from an outer edge of the outermost support to an inner edge of the joint between the first and second sheets, and b is a distance between the first and second sheets at the outer edge of the outermost support.

Abstract: A vapor chamber that includes a housing including a first sheet and a second sheet opposing each other and having respective outer edges of the first sheet and the second sheet joined together; an operation fluid enclosed in the housing; a wick on an inner surface of the first sheet and/or an inner surface of the second sheet; a first pillar on the inner surface of the first sheet and/or the inner surface of the second sheet and that defines a cavity in the housing; and a second pillar on the inner surface of the first sheet and/or the inner surface of the second sheet and configured to prevent the housing from being warped when heated to join the first sheet and the second sheet together.

Abstract: A vapor chamber that includes a casing, a pillar in an internal space of the casing and that supports the casing from an inside thereof, a working fluid in the internal space of the casing, and recessed portions in at least a portion of a main external surface of the casing.

Abstract: Provided is a powder supply device that can stably supply powder from a main hopper to a powder supply means including a sub-hopper without requiring component replacement and the like. The powder supply device is provided with: a first piping that guides powder accumulated in a main hopper downward; a second piping that is connected to the first piping at a lower end portion thereof while intersecting with the first piping, and that guides the powder guided by the first piping to a sub-hopper; and a switching valve that pressure-feeds the powder temporarily deposited while forming an angle of repose at an intersecting portion of the first piping and the second piping, to the sub-hopper.
