摘要: A turbine nozzle (2) that, among components constructing a turbine, reaches particularly high temperature is efficiently cooled with a relatively simple structure. A double casing structure in which a turbine casing (7) is provided outside a turbine shell (5) is formed. The turbine casing (7) functions as a flow path (24) for compressed air (20→21) before combustion. The turbine shell (5) covers a turbine nozzle (2) and a radial turbine impeller (3) and forms flow paths (15, 16) for combustion gas (10→11→12→13). The compressed air (21) before combustion flowing in the flow path (24), for compressed air, having air-tightness between itself and the outside air is blown to the turbine nozzle (2) through a through-hole (51) penetrating both wall surfaces of the turbine shell (5) so that the turbine nozzle (2) is evenly cooled and the compressed air used to cool the turbine nozzle is made to flow toward the turbine impeller (3).

摘要: A centrifugal compressor is equipped with an impeller having a blade angle distribution that makes it possible to achieve a relatively wide operating range. The blade angle of a shroud side facing a circular plate of a blade is termed a first angle and a blade angle of a hub side disposed at the circular plate is a second. The shroud side is formed in a curved shape having an angle distribution from a front area in a shaft direction toward a centrifugal direction in which the first angle is the local maximum point before a substantially middle portion and the local minimum point after the substantially middle point. The hub side is formed in a curved shape having an angle distribution from the front area in the shaft direction toward the centrifugal direction in which the second angle is the maximum local point before the substantially middle portion.

摘要: A digital signal transmission system adopting a quadrature amplitude modulation and demodulation principle and feasible for large capacity data transmission in which a number of levels are used. Each of a modulating and a demodulating device of the system is constructed to shift the phase difference between two carrier waves by a suitable angle of .DELTA..theta. radian from .pi./2 radian. The tuning phase in the demodulating device is limited to one so as to allow a bit error rate characteristic to remain constant.

摘要: In a demodulation circuit, a timing synchronizing circuit generates a timing signal representing a sampling timing of an A/D converter and has a timing signal generator, a polarity identification circuit and a logic circuit. The timing signal generator is phase-controlled by a phase control signal and generates a timing signal. The polarity identification circuit identifies a polarity of a differential coefficient of the baseband signal at a sampling point of the A/D converter and generates a polarity identification signal. Upon logic processing, the logic circuit supplies to the timing signal generator the phase control signal representing a deviation of an actual sampling point of the baseband signal from an optimal sampling point. A carrier asynchronism detection circuit detects an asynchronism state of a carrier regenerating circuit and supplies to the timing synchronizing circuit a signal which changes its loop parameter.
