Abstract: A gas turbine engine includes: a plurality of combustors disposed so as to incline radially outward from a turbine side toward a compressor side; and a diffuser inner tube and outer tube forming a diffuser as an upstream portion of a path that introduces a compressed gas from the compressor to the combustors. A transition duct portion of each combustor has such a shape that a circumferential dimension thereof gradually decreases from the turbine side to the compressor side so that a circumferential gap is formed between the transition duct portions. Downstream-side portions of the diffuser inner tube and outer tube each have a shape gradually increasing in diameter toward the downstream side. A turbine-side end of the circumferential gap at an inner diameter side of the transition duct portion is positioned radially inward of an imaginary extension conical surface continuous from the diffuser inner tube.

Abstract: An optical module for an optical device and an optical fiber is constituted by a pre-molded plastic package. In forming the plastic package, the main flowing direction of the molding resin is substantially parallel with the optical axis of the optical fiber. The optical module is formed by molding the resin by injection using pressure and then solidifying the resin. When the plastic package is formed by comprehensive molding, the flowing direction of the resin is parallel with the optical axis direction of the optical fiber to be installed in the optical module. As a result, for comprehensive molding, the molding pressure applied to the optical fiber is reduced. By using the resin case that is formed, the resulting package exhibits high rigidity and low thermal expansion properties in connection with the flowing direction of the resin, thus reducing the external stress and thermal stress applied to the optical fiber.

Abstract: The present invention is to reduce the package cost and secure the high reliability in an optical module having an optical device and an optical fiber.

Abstract: An amplitude detection circuit detects the peak value of an output signal of a photo-detector amplified by a head amplifier. The peak value detected by the amplitude detection circuit is read into a drive controller, and compared with a target value suitable for coding in a binary format a detected signal. The gain of a variable gain amplifier is adjusted accordingly. Consequently, an analog signal processing circuit can stably codify the detected signal in a binary format. Under the control of the drive controller, a recording power level calculation circuit determines a test writing power level with which test writing is performed on a test track of a magneto-optical disk. The recording power level calculation circuit then calculates an actual record power for each zone of the magneto-optical disk according to the test writing power level.
