Abstract: A projection video display device, which enlarges and projects an image from an image-displaying means, has a housing and a raisable/lowerable mirror and a power supply, a light source, and a lens unit inside the housing. The raisable/lowerable mirror covers a projection-light opening formed in the top surface of the housing and able to rotate with respect to the housing, and has a convex mirror on the inside surface thereof. The raisable/lowerable mirror covering the top surface of the housing forms a smoothly connected, smooth, convexly curved surface with no height difference between the edge of the raisable/lowerable mirror and the front edge of the opening, and a half-bowl-shaped concavity is formed on at least one side of the raisable/lowerable mirror in the direction of the axis of rotation thereof.

Abstract: Without increasing the size of a projection video display device that has a mirror that can be raised and lowered, this invention makes it easy to raise and lower said mirror. In order to do so, this projection video display device, which enlarges and projects an image from an image-displaying means, has a housing (10) and a raisable/lowerable mirror (30) wherein: a power supply, a light source, and a lens unit are accommodated inside the housing (10); said lens unit enlarges light from the light source after said light has been directed to the aforementioned image-displaying means; and the raisable/lowerable mirror (30) covers a projection-light opening (26) formed in the top surface of the housing (10), is provided so as to be able to rotate with respect to the housing (10), and has a convex mirror (110) on the inside surface thereof.

Abstract: A light emitting device is manufactured in which a cap having a frame portion is bonded to a package having a light emitting element mounted in a recess of the package to cover an opening of the recess. A method for manufacturing the light emitting device includes: partially disposing a metal bonding agent, having greater wettability to the frame portion than to the package, to one of the package and the frame portion; and bonding the package and the frame portion by extending the metal bonding agent along the frame portion so that ends of the metal bonding agent are joined to each other while defining a space at a joining portion where the ends of the metal bonding agent are joined.

Abstract: A light emitting device uses a conductive bonding agent in bonding a package and a cap, and the light emitting device is a non-air tight and can be manufactured stably, with an improved yield. A method of manufacturing the light emitting device includes a step of bonding a cap having a frame portion to a package having a light emitting element mounted in a recess of the package to cover an opening of the recess. In the step of bonding, a metal bonding agent having greater wettability to the frame portion than to the package is partially disposed to the package or the frame portion, and extended along the frame portion so that ends of the metal bonding agent are joined to each other. With this, a space is defined at a joining portion where the ends of the metal bonding agent are joined, and the package and the frame portion are bonded.
