A combustor includes: a fuel nozzle for injecting fuel; a combustion liner surrounding a combustion space for combusting the fuel and having an internal passage having an outlet communicating with the combustion space; and an air-fuel mixture line, connected to an inlet of the internal passage of the combustion liner, for introducing an air-fuel mixture containing the fuel and compressed air to the internal passage. The combustion liner is configured to be cooled by the air-fuel mixture flowing through the internal passage.

Combustor and gas turbine including the same

A combustor nozzle includes a nozzle main body extending along an axis. The nozzle main body includes a first fuel passage which extends along the axis and through which first fuel is configured to flow, a first fuel ejection passage which extends to an outer circumferential surface of the nozzle main body toward a distal end side thereof from the first fuel passage and is configured to eject the first fuel from the outer circumferential surface, an air flow passage which extends in an axial direction on a radial outer side of the first fuel passage with respect to the axis and through which purge air is configured to flow, and an air ejection passage which extends from the air flow passage toward a center of a distal end of the nozzle main body and is configured eject the purge air from the center of the distal end.

Digital camera

An operating device is provided having a supporting member, a button, an elastic member, and a bearing member. The supporting member has an opening which passes through the thickness direction of the supporting member. The button has a shaft and an engaging portion. The shaft is arranged such that the axial direction of the shaft is parallel to the thickness direction of the supporting member. The engaging portion projects parallel to the axial direction of the shaft. The elastic member is set onto the supporting member so as to cover the opening, and has a projecting portion which engages the end of the shaft. The bearing member is provided between the supporting member and the elastic member, which is provided around the opening and is located nearer to the shaft than the engaging portion in the direction orthogonal to the projecting direction of the shaft. The shaft may press the elastic member so that the elastic member is deformed so as to move along the thickness direction of the supporting member in the opening.

Operating device

An operating device is provided having a first button, a second button, and a regulating member. The first button has a tubular hole having a bottom, and is able to be pressed in the direction from the opening edge of said tubular hole to the bottom. The second button freely fits the inside surface of said tubular hole on the outside surface of the second button. The regulating member engages the edge of the first button and regulates the movement of the first button in the pressing direction. The first button is swingable on its edge.

A circuit board is to be provided on outer surfaces of an internal camera body having a containing section to hold an element of a camera. The containing section has an opening on one of the outer surfaces of the internal camera body. The circuit board has a bendable portion that allows the circuit board to bend thereat; and a leaf portion that is connected to the remaining part of the circuit board only with the bendable portion. The leaf portion covers the containing section when the leaf portion is not bent at the bendable portion, and is located to expose the containing section to outside when the leaf portion is bent at the bendable portion.

Circuit board for camera

A prism is provided having a surface on which light is made incident, surfaces at which light is reflected and a surface from which light is emitted. The prism includes an uneven surface portion provided on at least one of the incident, reflecting or emitting surfaces and located outside a light transmission area through which effective light of an associated optical system, in which the prism is to be incorporated, can be transmitted. The disclosure is also directed to a real image type view finder having such a prism.

Prism and real image type view finder

A parallax compensation system in a camera finder includes a mirror surface mounted to a mounting member. The mounting member is rotatably mounted to a mounting frame having protrusions about which the mounting member rotates such that the mounting member is rotatable about an axis defined on the mirror surface. A cam mechanism is rotatably mounted on a top surface of the mounting frame for regulation of the mounting member to have a predetermined position. An urging member biases the mounting member against the cam mechanism, so that when the cam mechanism is rotated, the mounting member is rotated about its axis according to a cam surface of the cam mechanism. The mounting member is rotated about the axis of the mirror surface to change an optical axis of the same to compensate for parallax.

Regulated parallax compensation system for a camera finder

An apparatus for adjusting the size of a picture image area and field frame of a view finder in an associated manner. The apparatus includes a picture image area restricting member which is linearly movable into and out of a photographing aperture, a field frame restricting member which is rotatably movable into and out of the field frame, a rotatable operating member for moving the picture image area restricting member, and a driving member which is linearly driven by the rotation of the operating member to rotate the field frame restricting member.

Coordinating mechanism for picture image area and field frame size

A remotely controllable camera system has a photodetector mounted in a camera housing and facing a front panel thereof. The photodetector detects an external optical command signal beam applied thereto through the front panel. The camera system also has an optical fiber for guiding an external optical command signal beam applied through a rear panel of the camera housing toward the photodetector. The external optical command signal beam is transmitted from an infrared remote controller which may be positioned in front of or behind the camera. The camera has an electrically controllable shutter that can be released in response to the external optical command signal beam detected by the photodetector.

Remotely controllable camera system

A movable member positioning mechanism in which the number of components of lock and click mechanisms is decreased, and the number of assembling steps is decreased accordingly. In the movable member positioning mechanism, a remote controller 20 is movably arranged along an inner wall 11 of a housing 10, a locking pawl (K) is arranged between the inner wall 11 and an outer wall 12, a lock hole 21 and a click hole 22 are formed in the surface of the remote controller 20 which is confronted with the inner wall 11, and the locking pawl (K) comprises: a lever 14 extended between the inner wall 11 and the outer wall 12; a locking portion 17 which is formed at one end of the lever 14 in such a manner as to be able to engage with the lock hole 21 and the click hole; an operating portion 16 which is formed at the other end of the lever 14 so as to cause the locking portion 17 to protrude towards the remote control 30 through the inner wall 11; and a spring member 18 for urging the locking portion 17 towards the lock hole 21 and the click hole 22.
