IPC: F22B1/18
Filed: 1990-06-08
Abstract: PURPOSE:To shorten starting time as the whole electric power plant by connecting together the high pressure drum and the low pressure drum of an exhaust heat boiler through a connecting pipe, and providing a control valve on the way of the connecting pipe. CONSTITUTION:A combined-cycle electric power plant is constituted out of a gas turbine l, a steam turbine 15, and an exhaust heat boiler 2. The high pressure drum 17 and the low pressure drum 11 of the exhaust heat boiler 2 are connected together through a connecting pipe 30. A control valve 31 is provided on the way of the connecting pipe 30. By circulating water between the low pressure drum 11 and the high pressure drum at starting, rise of steam pressure and temperature of the low pressure drum 11 can be quickened. By decrease of the water flow from a high pressure circulating pump 18 to a high pressure evaporator 4, heat absorption of the high pressure evaporator 4 is decreased and the heat absorbing quantity of a low pressure evaporator 7 is increased by the portion. In this way, the rising speed of steam pressure and temperature of the low pressure drum is quickened, the warming time of the exhaust heat boiler can be shortened, and the starting time as the whole plant can be shortened.

Title: Detection of positioning mark for electron beam exposure
Inventor: KUSAKABE HIDEO
IPC: H01J37/304
Filed: 1980-10-29
Abstract: PURPOSE:To reduce a detection error of positioning mark for electron beam exposure by a method wherein the position of the center of a mark to be detected is transferred to the neighborhood of the origin of the electron beam scanning system, and the position thereof is detected. CONSTITUTION:An arm 3a of mark in the Y direction is scanned in the X direction at the partial positions X1...Xn, reflected electrons are detected and stored, the feedback straight line A in the Y direction is calculated, the feedback straight line B is calculated in the same way to obtain the coordinate of the central point P (x1, y1) of the mark from the intersection (electron beam scanning system coordinate), those are reduced to the measured value x0, y0, and the coordinate x0+x1, y0+y1 of the point P are detected. When the electron beam scanning system coordinate is rotated at an angle theta in relation to the length measurement system coordinate, the more the scanning system coordinate (x'1, y'5) of the point P is remote, the more the error according to the angle theta of the length measurement system coordinate (x1, y1) is increased. Therefore when the center P of the mark is transferred to the neighborhood of the origin of the beam scanning system coordinate and the position thereof is detected, detection error of the central position P can be reduced even when the beam scanning system is rotating by regulation.

Abstract: PURPOSE:To attain saving of equipment and of man-hour in the maintenance of a line by inserting a low pass filter means forming a smoothing circuit to an output of the 2nd level detecting means detecting narrow band level so as to smooth the output signal of the 2nd level detecting means. CONSTITUTION:An intermediate frequency amplifier consists of a variable gain amplifier 11, the 1st level detection means 13, a band pass filter means 15, the 2nd level detection means 16, an AGC amplifier 14, a low pass filter means 17, and a squelch control circuit 18. In the circuit of the low pass filter means, the resistors 22, 23 are adjusted to set properly the cut-off frequency thereby setting the degree of signal smoothing and the detection speed properly. The low pass filter means 17 is inserted and the detected output is not lowered up to '0' in inputting a sweep signal, then malfunction is prevented by setting the squelch setting point to a minimum input voltage level or below. As a result, even when the sweep signal is inputted to an AGC amplifier 14, since the repetition of on/off operation is avoided, the line characteristic is measured.

Abstract: PURPOSE:To control amount of cold air passing through a vacant slot or individual electronic circuit packages, by providing a guide pin on each electronic circuit package for pushing an L-shaped arm to rotate the same so that air resistance is regulated by a guide vane. CONSTITUTION:When a slot is vacant and no electronic circuit package is inserted therein, a guide vane 1 is turned to the transverse position by tension of a spring 3 to close the passage of cold air. When a package 9 is inserted into the slot, a guide pin 11 pushes a rod 15 of an L-shaped arm 4 to rotate the same and the guide vane 1 is thereby turned to the vertical position to open the passage of cold air. The side edge of a fan type plate 14 engaging the guide vane 1 takes various positions according to rotational angular positions of the L-shaped arm 4. Accordingly, passage condition or amount of cold air can be regulated by changing the position of attaching the guide pin 11.
