Abstract: PURPOSE:To intend suppression of eluting out of metallic component form a heat tranfer tube by forming a highly corrosion resistive glossy annealed skin on a surface of the heat transfer tube of a moisture separator heater. CONSTITUTION:A basic material of a heat transfer tube 3a of moisture separator heater 3 is constituted of a stainless steel of a ferrite system and, on the surface thereof, a glossy annealed skin is formed. The glossy annealed skin is formed by holding the basic material during predetermined time in reductive atmosphere at around 800 to 900 deg.C. Heated steam sent into the tube 3a, is condensed through heat transferring with main steam flowing outside the tube and finally is completely drained to the outside. the drainage is at a temperature as higher as 235 to 282 deg.C and therefore the temperature region is strictly corrosive one for a stainless steel of ferrite system, however, since the highly corrosion resistive glossy annealed skin is formed on the surface corrosion of the tube 3a is extremely reduced and an amount of eluting out metal is substantially diminished.

Abstract: PURPOSE:To improve processing capacity by extracting a subject to be renewed after detecting the presence or absence of the subject in the space higher in position than the page unit and a segment area. CONSTITUTION:A space table 1 consists of plural segments and each segment contains a reference bit A. A space table retrieving part 5 retrieves the table 1 and the ON/OFF of the bit A. Then the part 5 outputs logic value ''0'', for instance, when the bit A is turned off. Then a non-replacement state is decided via an inverter circuit 7, and a processing part 10 performs processing. When the bit A is kept on, a segment retrieving part 6 is actuated to retrieve only segments belonging to the ON state of the bit A of the table 1. The segment of non-replacement is processed via an inverter circuit 8. A page table retrieving part 11 also performs the same action as the part 6 and processes the ON state of the bit A within a page table 3 as a subject to be renewed through the part 10.

Filed: 1984-10-12
Abstract: PURPOSE:To eliminate the reliability of a detection output without lowering the response, by controlling the scanning of a scanning circuit by an output of a detection circuit so as to increase the detection speed of an object while an output is generated when objects are detected beyond a specified number. CONSTITUTION:A drive pulse from a pulse driving circuit 6 is applied sequentially to light emitting elements 1a-1e by switching operation of a scanning circuit 7 and a light receiving element 2 receives reflected light from an object. Then, a scanning circuit 7 courses a scanning so that either the projection area with the light emitting elements 1a-1e or the light receiving area with the light receiving element 2 or both thereof will be altered in sequence electrically or mechanically. A control circuit 12 controls the scanning of the scanning circuit 7 to increase the detection speed of an object by an output of a comparator 9 of a detection circuit. A decision circuit comprising an integrator 10 and a switch circuit 11 produces an output when the outputs of the detection circuit are detected beyond a specified number. Here, when the element 2 receives reflected light, the scanning of scanning circuit is stopped so that the reception of light will be continued and the decision circuit increases the sampling speed of the output of the detection circuit at the stopping of the scanning.
