摘要： PROBLEM TO BE SOLVED: To shorten the time required for resetting a plant to a predetermined load by making a decision that combustion is abnormal when the combustion state of a combustor or a gas turbine exceeds an allowable value and sustaining the operation while lowering the gas turbine load down to a partial load. SOLUTION: Combustor metal temperature 13 of a plurality of two stage combustors 1 arranged around a gas turbine is detected by means of total n thermocouples 11 fixed to the second stage combustion section of each combustor 1. Operating unit 17a-17c take in the measurement of respective combustor metal temperatures 13 and when any one of individual allowable temperatures, fluctuation widths or variation rates of the measurements exceeds a preset allowable value, a decision is made that combustion is abnormal and signals 18-20 are delivered. As an example, allowable temperature is set at 750 deg.C while taking account of the melting point of material at the combustor metal part thus protecting n apparatus against damage.

摘要： PURPOSE:To provide a facsimile device capable of saving power and performing automatic transmission and polling at a low cost. CONSTITUTION:When a stepping motor 1 is rotated in the direction A, a cam 25 is rotated, and a transmission switching arm 30, an RS arm 37 (cut switching arm 35), and a reception switching arm 33 are shifted. The engagement state of gears is switched to the state corresponding to the transmission or reception mode. A mode switch 29 detects the rotation position of the cam 25, and the mode switching is controlled based on it. When the stepping motor 1 is rotated in the direction B, the rotation is transmitted to a platen roller 4, a separating roller 10, a sensor roller 14 and a cutter block 8 in response to each mode, and a sheet is conveyed and cut.

摘要： PROBLEM TO BE SOLVED: To provide a steam turbine, a steam turbine plant system, and an output increasing method for steam turbine capable of increasing the output by raising the performance of a high-low pressure integrated type turbine in which a high pressure part and a low pressure part are integrated and by utilizing its surplus steam effectively.
SOLUTION: A steam drainage hole 20 is provided in the prescribed place prior to the low pressure part L and a pressure regulating valve 35 is installed to discharge the steam as surplus for the low pressure part L from the steam drainage hole 20 by controlling the steam. The steam within the range of the rated pressure for the high pressure part H and surplus for the low pressure part L is introduced to the high pressure part H so as to perform high-load operation in the high pressure part H, while the surplus steam is introduced to the low pressure part L after discharged from the steam drainage hole 20. Thereby the output can be increased.

摘要： PURPOSE:To perform shading correction based on a white reference value by accurately detecting the white reference value without being limited by the object depth on the document side of a read sensor. CONSTITUTION:A white reference part 2b is provided on a part of a carrying roll 2 of a reader 1, and the whole of the carrying roll 2 including the white reference part 2b is closely brought into contact with a read sensor 3, and shading correction of the whole including a paper feed part 2a is performed based on the white reference value of the white reference part 2b. The coefficient of friction of elasticity of the white reference part 2b is reduced to prevent sticking of dust or the like, and that of the paper feed part 2a is increased to surely carry the document. Consequently, the white reference is accurately detected and shading correction is stably performed without restrictions due to the object depth of the document side because the white reference part is always placed on the read sensor surface. Since the whole of the carrying roll including the white reference part is closely brought into contact with the read sensor, the document is not floated and is surely read.

摘要： PURPOSE:To prevent a wrench from occurring even in fitting to or separating from a roller by a method wherein a roller is freely rotatably with a bearing component on an outer periphery of the bearing component. CONSTITUTION:A bearing component 7 of a shaft 2b of a platen roller 2 is supported with support components 8a, 8b of the platen roller 2. A roller 9 has a form capable of being rotated on the outer periphery of the bearing component 7. Herein, when a thermal head 1 and the plated roller 2 perform opening and closing operations, bearing grooves 3a', 3b' of positioning components 3a, 3b fit to or separate from the roller 9. A relative positional 2 is kept constant. Further, since the roller 9 performs rotary operation on the outer periphery of the bearing component 7 when the bearing grooves 3a', 3b' of the positioning components 3a, 3b fit to or separate from the roller 9, fitting or separation is smoothly performed, and abrasion of contact parts between the bearing grooves 3a', 3b' of the positioning components 3a, 3b and the bearing components 7 is apt to be decreased.

摘要： PURPOSE:To facilitate the replacement of an ink film by providing a member having a mechanism which engages with an engagement part on the other end of paired spools and fits the paired spools after the positional control of the spools in an axial direction, on the other end of the interior of a cassette. CONSTITUTION:Three end parts of both ends of each spool 8, 9 on the winding side and supply side of an ink film 7 are formed so that they become engaged in the same manner. Only the other one end is formed so that it becomes engaged in a different manner. In a cassette, members 2, 2', 3 which can become engaged with the engagement parts on the ends of paired spools 8, 9 and a member 4 which can become engaged with only the other end are provided. Consequently, when the spools of an ink film on the winding side and those on the feed side which are paired with the former are attached to the cassette 1, no erroneous attachment occurs.
