Abstract: A power unit control system includes: a gas turbine including a turbine rotor; an energy converter being able to operate as a power generator that generates electric power with rotation of the gas turbine; a battery that stores electric power generated by the energy converter; a reception portion that receives a signal which is transmitted from a device controller that controls a device operating using the electric power stored in the battery or electric power generated by the energy converter; and a control portion that performs rotation speed increase control which increases the rotation speed of the gas turbine to a predetermined rotation speed when a predetermined first signal is received by the reception portion.

Abstract: In a gas turbine engine, an inside turn duct portion and a nozzle guide vane are engaged together via an engagement part. An axially forward-facing load acting on a reverse flow combustor is transmitted to the vane via the engagement part. Therefore, it is possible to counteract an axially backward-facing load acting on the vane from combustion gas with the axially forward-facing load, thus reducing a bending moment acting on a support part of the vane and enhancing durability. Furthermore, part of the axially forward-facing load acting on the combustor acts on the support part via the vane. The axially forward-facing load acting on the support part of the combustor without via the vane is decreased by the above-mentioned part. Thus, it is possible to reduce bending moments acting on an outside turn duct portion and dome portion of the combustor and enhance durability, thereby preventing degradation of combustion performance.

Abstract: A new type of display unit is provided. A light emitting body such as a fluorescent lamp is disposed behind an elongated display panel. The middle section of the fluorescent lamp extends parallel to the elongated display panel to face it from end to end. The opposite ends of the lamp are bent if necessary.

Abstract: A display apparatus having a plurality of display units arranged contiguously so as to form mosaic patterns on the display apparatus by varying in the contents of display according to control signals given thereto. The display unit includes a fluorescent lamp, a display element, a fluorescent lamp stabilizer, a glow lamp for lighting the fluorescent lamp, and a case. All these components of the display unit are accommodated in the case, so that the display apparatus is formed in a compact construction and the electronic circuits of the display units are not disturbed by noises attributable to the current flowing through the cables connecting the fluorescent lamp stabilizers to the fluorescent lamps, respectively.
