Abstract: A connector for a multilayered board to connect a flat cable to a middle layer of a multilayered board while minimizing the impact due to variations in the dimensional precision and strength of multilayered boards and/or preventing deformation of the multilayered board and improving contact stability. The connector includes a board-side connecting portion and a cable-side connecting portion. The board-side connecting portion includes a column-shaped terminal, and the cable-side connecting portion includes flat terminals. The column-shaped terminal protrudes from the middle layer of the multilayered board in the thickness direction. The flat terminals include resilient contact portions, contacting a side surface portion of the column-shaped terminal from the width direction of the insertion slot in response to insertion of the cable-side connecting portion into the insertion slot.

Abstract: A sealed lamp device may include a discharge lamp burner; a concave mirror opened to a front direction and reflecting radiation light of the discharge lamp burner to the opened side, an optical axis of the concave mirror being aligned with an optical axis of the discharge lamp burner; a hollow casing structure having an opening section in a front side, to which the concave mirror opened out; and a front plate closing the opening section of the hollow casing structure and emitting the radiation light. The hollow casing structure may be made wider than an opening width of the concave mirror, so as to increase a sealed volume occupied by the discharge lamp burner.

Abstract: Disclosed herein is a lamp cooling device for cooling a lamp including a light emission source for emitting light, a front transparent plate, a reflector for reflecting light emitted by the light emission source toward the front transparent plate, the light emission source being disposed in an intralamp space surrounded by the front transparent plate and the reflector, said lamp cooling device including: a duct having joint ports defined in respective opposite ends thereof and communicating with said intralamp space, said duct having a continuously extending portion between said opposite ends which is disposed in a space outside of said intralamp space, for circulating a gas through said duct and said intralamp space in isolated relation to the space outside of said intralamp space.

Abstract: There are provided a multilayer disc manufacturing apparatus and method, capable of computing a rotational eccentricity of a disc with no contact with the disc and a high accuracy, and producing the disc with lower costs without having to rotate the disc or perform any complicated operations. The multilayer disc manufacturing apparatus (100) is for manufacturing a multilayer disc by bonding one disc (220) to another disc (210).
