摘要:
A gas turbine includes a nozzle vane and a sealing unit engaged with the nozzle vane inside a turbine supplied with combustion gases produced by mixing and burning air for combustion and fuel. The nozzle vane and the sealing unit are disposed in a channel of the downward flowing combustion gases on the outlet side of a gas path. A plurality of engagement portions between the sealing unit and the nozzle vane are provided successively from the upstream side toward the downstream side in a direction of flow of the combustion gases, and a downstream one of the plurality of engagement portions has a contact interface formed in a direction across a turbine rotary shaft. A reduction in the thermal efficiency of the gas turbine can be suppressed.

In the transmitter receiver of the present invention, a light-shielding sheet is arranged in front of a light-emitting portion having a LED whose light-emitting central axis is inclined and an aperture from which only the head of the light-emitting portion is exposed is made in the light-shielding sheet. The light-shielding sheet masks the inclined side portion of the light-emitting portion to prevent a light-receiving portion from detecting the light leaking from the inclined side portion. Therefore, the light-receiving portion can detect with high accuracy a change in the amount of light emission that is produced by a change in the direction of the light-emitting portion.

According to this invention, a recording/reproducing device includes a DC motor for driving cam plates in the horizontal direction, a sensor for detecting positions of the cam plates in the horizontal direction, and a horizontal cam groove portion which is formed on at least one end portion of the cam grooves and with which the cam pins of the pickup unit are brought into contact. The cam plates are driven in the horizontal direction by the DC motor, the cam pins of the pickup unit are brought into contact with the horizontal cam groove portion, and, at this time, initialization of the cam plates is performed by causing the sensor to detect the positions of the cam plates in the horizontal direction.

A lower surface and an upper surface are provided in a detection panel 2. Lower electrode layers 11a and 11b, a lower wiring pattern 15, and a lower land portion 13 formed on the lower surface are covered with upper shielding layers 28a and 28c of the upper surface, and an upper electrode layer 21, an upper wiring pattern 25, and an upper land portion 23 formed in the upper surface are covered with lower shielding layers 19a and 19b of the lower surface. Therefore, an effect of a decorative area shielding light may be enhanced, and thus an electrical shielding effect may further be exhibited.

There is provided a small-sized vibration generator that resonates at two different frequencies. A movable base is housed inside a case. The movable base has an installation plate, and supporting plates bent at right angles from both ends of the installation plate. A first elastically deformable portion is formed integrally with the installation plate, and a weight body is supported by the first elastically deformable portion. In the movable base, a second elastically deformable portion is provided between the installation plate and the supporting plates, and the supporting plates are fixed to supporting end plates of the case. The bending elastic modulus of the second elastically deformable portion is higher than the bending elastic modulus of the first elastically deformable portion, and resonates at two natural frequencies when a driving force is applied to the weight body by a magnetically-driven portion.
