摘要： PURPOSE:To prevent the increase of the stop time of a gas turbine owing to a draft force generated by a chimney effect. CONSTITUTION:A branch duct 11 having an air intake port 10 and a valve 12 is installed in the middle of an exhaust duct 8 through which exhaust gas from a gas turbine 6 is guided to a chimney 9. This constitution prevents the increase of a stop time owing to a draft force by a chimney effect during the stop of the gas turbine. Through utilization of the draft force generated by the chimney effect, turning operation of the gas turbine is practicable without using other power of a starting device.

摘要： PURPOSE:To inspect the pressure proof of high pressure piping simultaneously with the assembling and adjusting operation of high pressure turbine casing by sealing an annular space which includes a weld line and contacts the high pressure casing and the pipe to be inspected by packing. CONSTITUTION:A high pressure lower half casing 1 is set and then a main steam pipe 4 and further a steam control valve are set; while respective pipes 4 are welded temporarily simultaneously with the assembly of a high pressure upper half casing 2, a specific heat treatment is carried out to weld respective parts. Then, annular packings 18 and 18' which are sectioned in a C shape are brought into the casing 1 and pipe 4 to seal the annular space W contacting the weld line W, and further packing pressers 19 and 19' are used to back up the packings 18 and 18'. In this state, pressure liquid is injected into the space sealed by the annular packings and pressurized to detect whether or not there is the defect of the weld zone W.

摘要： PURPOSE:To greatly shorten the alignment operation for a turbine by installing a gas turbine, a power generator and a steam turbine with use of a level adjuster member formed to have a thickness and a gradient corresponding to the installation level after completion of the installation. CONSTITUTION:A sole plate 5 is preliminarily installed, via level adjusting bolts 3, on plates 2 fixed on the upper surface of a turbine base 1. After the upper surface of the sole plate 5 is adjusted to a predetermined level by the level adjusting bolts 3, grout pads 6 are hammered into between the sole plate 5 and the turbine base 1. Further, the upper surface of the sole plate 5 is previously made to have a level and a gradient which are based on a linear alignment diagram of the turbine as a whole. By forming to a prescribed thickness a base pad 7 fixed to the bottom of a leg portion of a turbine casing 10, it is possible to install the turbine casing 10 to a predetermined position. This can shorten the installing operation time period in the constructing field.

摘要： PURPOSE:To reduce installation area and cut down the cost of constructing the building by arranging gas flow of both burner and regenerator to be horizontal and at a right angle to the body of the turbine. CONSTITUTION:The turbine enclosure 17 is formed to enclose the compressor wheel chamber 13, the turbine wheel chamber 14, the turbine intermediate casing 15 and the suction air plenum 16, etc., a burner enclosure 20 is attached to the turbine enclosure 17 to be freely attached and detached, in the form to surround the outer cylinder of the burner 18. Further, a horiozontal type regenerator 22 is connected to the turbine exhaust port 23 so that its flow derection may be perpendicular to the turbine body 11, and all the accessories other than covered by the turbine enclosure 17 are enclosed by the outer cover 30. By this arrangement whole equipment of the turbine can be installed compactly as a package type, and units sent from the manufacturer's plant per each enclose can be immediately assembled as it is on the site, and operated.

摘要： PURPOSE:To stabilize stacking attitude in a roll-over transfering device for a shadow mask for a color CRT by inching the roll-over device and a conveyor as much as they are relatively offset so that products can be shifted and stacked on the conveyor. CONSTITUTION:A mask 21 which is taken out of a molding device is put on a mask supporting member 22 in a roll-over device 10. The mask 21 is retained by the grip 23a of an air cylinder 23 and the roll-over device 10 is moved to the side of a belt conveyor 30 by an air cylinder 14. The mask 21 is rolled over by an air cylinder 19 and placed on the conveyor 30, when the grip 23a is relieved from retention. In case of repeated operation for stacking, a sensor 32 detects the mask to inch the conveyor 30 until a sensor 31 is turned off. In this way, stacking is performed in a stable condition.

摘要： PURPOSE:To remarkably reduce the consumption of water at the time of a pressure test and to greatly reduce the man-hours for operation by charging a water amount exclusion member which substitutes for the volume of a part of injection water and has smaller specific gravity than water in a pressure container. CONSTITUTION:Plural spherical bodies 23 for gas charging are formed in the pressure container while linked with one another by communicating pipes 25, which are connected to a gas cylinder 7. When the pressure test is taken, the water amount exclusion member 2 is charged in the pressure container 1 and then the communicating pipes 25 and sealed from the pressure container 1 with water and connected to the gas cylinder 7 through a gas pressure origin valve 9, which is opened until the bodies 23 for gas charging swell as specified to apply pressure with the gas of the gas cylinder 7. In this case, the water amount exclusion member 2 has no variation in volume because of pressure proof structure, and water for hydraulic pressure can be reduce greatly to reduce and shorten the operation man-hours and time for water filling and water discharging and also facilitate the operation, thereby reducing the cost.
