摘要： A nozzle box 10 includes: a lead-in pipe 20; a bent pipe 30 connected to the lead-in pipe 20 and formed so as to change a direction of a channel center line 50 to an axial direction of a turbine rotor 212; and an annular pipe 40 connected to the bent pipe 30 and leading steam to a first-stage nozzle 213a while spreading the steam in a circumferential direction of the turbine rotor 212. In the steam channel lead-in part structure 10, from an inlet of the lead-in pipe 20 toward an outlet of the annular pipe 40, steam channel widths Sa-1 to Sn-1 in a first direction intersecting with the channel center line 50 gradually increases and steam channel widths Sa-2 to Sn-2 in a second direction intersecting with the channel center line 50 and perpendicular to the first direction gradually decreases.

摘要： A high temperature steam valve has a valve casing including a main steam inlet, a main steam outlet and a valve chest. The high temperature steam valve also has a valve seat positioned in the valve chest, a valve element facing the valve seat, and a valve rod slidably penetrating the valve casing to drive the valve element. A cooling steam hole is provided to surround a valve-rod penetrating portion of the valve casing. Cooling steam can be poured into the cooling steam hole from outside through a cooling steam inlet hole and steam having finished heat exchange can be exhausted from a cooling steam outlet hole into the valve chest. The sliding portion between the valve rod provided in the valve-rod penetrating portion of the valve casing and bush is cooled to prevent oxidized scale from depositing on the sliding portion.

摘要： An image transmission system includes a modulating part for independently modulating a luminance signal and two kinds of color difference signals and a demodulating part for independently demodulating the modulated luminance signal and the two kinds of modulated color difference signals. The demodulating part includes a signal correcting part for shifting at least one of the modulated luminance signal and the two kinds of modulated color difference signals by a predetermined number of picture elements in a scanning line direction to correct an error introduced by the modulation.
