Abstract: A blade ring assembly including: a turbine blade ring extending in a circumferential direction about an axis; a component to be cooled, disposed on an inner circumferential side of the turbine blade ring; and an outer circumferential side component disposed on an outer circumferential side of the turbine blade ring. The turbine blade ring has a cooling medium intake port leading from an outer circumferential surface to an inner circumferential surface of the turbine blade ring. The outer circumferential side component includes: a first wall portion which covers at least a portion of the cooling medium intake port from the outer circumferential side of the turbine blade ring; and a second wall portion which extends from an end portion of the first wall portion on the axially downstream thereof toward the outer circumferential side of the turbine blade ring.

Abstract: The present invention provides a printed wiring board free from undercuts, which can be formed by an additive method without a dry treatment and a dry treatment apparatus, and a production method thereof. A printed wiring board of the present invention has a conductor circuit free from undercuts which is produced by carrying out additional plating to fill undercuts.

Abstract: A rotary dial device having a click stop mechanism, includes a stationary member; a rotary dial rotatably supported by the stationary member; a ball guide groove formed on the stationary member to extend in a radial direction of the rotary dial; a ball positioned in the ball guide groove; at least one protrusion and at least one depression which are formed on the rotary dial along one of two imaginary cylindrical surfaces with axes thereof on an axis of the rotary dial, the two imaginary cylindrical surfaces being positioned radially outside and inside the ball guide groove in the radial direction of the rotary dial, respectively; and a cylindrical resilient member positioned along the other of the two imaginary cylindrical surfaces to bring the ball into pressing contact with any one of the protrusion and the depression by resiliency of the cylindrical resilient member.

Abstract: A strobe mounting structure is used for retractably mounting a pop-up strobe on an upper portion of a single lens reflex camera having a pentagonal prism. The pop-up strobe has a strobe case which is movable between an operable position and a retracted position. The strobe case further has a pair of legs, which astride the pentagonal prism. Each of the pair of legs has a U-shaped cross section taken along a plane perpendicular to a longitudinal direction thereof. The strobe case is rotatably mounted on the upper portion of the single lens reflex camera by a shaft penetrating through opposing walls of each of the pair of legs.

Abstract: An operation apparatus for a water proof device includes an operation member which is rotatably or slidably supported on an outer surface of a water tight casing of a water proof device, a water tight transparent window formed in the casing that is covered by the operation member, a reflection type photocoupler provided inside the transparent window, and a reflection code pattern provided on the surface of the operation member that is opposed to the transparent window. The reflection code pattern is provided with different reflectances for light emitted from the light emitter of the photocoupler, so that the amount of light to be received by the light receiver of the photocoupler can be varied in accordance with the operation position of the operation member.
