Title: Method of corrosion protection in boiler water supply system
Inventor: KOBAYASHI TAKEO
IPC: F22D11/00
Filed: 1990-11-09
Abstract: PURPOSE:To form an oxide film on the surfaces of pipes that constitute a boiler supply water system and prevent the pressure loss caused by the compacted ferrous ingredients that are eluated on the surface of the piping by pouring oxygen into the boiler water so as to bring the oxygen content in the boiler water to a specified value. CONSTITUTION:In the trial operation of a boiler after the manufacture or right after the start of its operation, the oxygen 38 from an oxygen supply source 25 is poured into the boiler water through an oxygen pouring pipe 23 at a position of a piping 24 for connection between a deaerator 19 and a supply water pump 20 of the boiler water supply system 10. At this time the oxygen content in the boiler water 28 that flows in the piping 24 is measured by an oxygen content meter 27, and an instruction 29 of regulating the degree of opening is sent to an oxygen flow rate regulating valve 26 that is provided in the middle from the oxygen pouring pipe 23 to the oxygen content meter to bring the oxygen content in the boiler water 28 to 20-200ppb. With this arrangement, in the case of pouring oxygen 38 a perfect oxygen film is formed in which fine hematite particles 36 close the spaces among the coarse magnetite particles 35, and the oxide film 37 prevents the invasion of the boiler water and the eluation on the piping 24.

Title: Device for measuring magnification/angle of pattern
Inventor: ARAI TAKASHI
IPC: G03F1/00
Filed: 1993-11-10
Abstract: PURPOSE:To automatically measure the magnification and angle of a pattern by calculating the contour distances from the center of gravity of the pattern to contour pixels and plotting the contour distances at respective angle positions to form a graph and calculating the dispersion of a contour distance ratio. CONSTITUTION:The pattern (a) on a printing manuscript A and the pattern (b) on layout specifying paper B are inputted to a computer 100. Edge detection processing is performed with respect to the pattern (a) and the patterns (a), (b) are subjected to binarization processing to become a line image consisting of black and white pixels. The center of gravity of line image data is set as an end, point to define the half straight line Ltheta arranged at an arbitrary angle position theta and the black pixel present at the remotest distance from the center of gravity on the line Ltheta is determined as a contour pixel Ptheta. A contour line is constituted by the aggregate of pixels P, over 360'. The contour line is corrected in fault by smoothing processing and the distance rtheta of the pixel Ptheta and the center of gravity is calculated over 360 deg.. A graph taking positions theta on horizontal axes and the contour distances ratheta, rbtheta of the patterns (a), (b) on vertical axes are formed. The ratio rbtheta/rtheta at the position theta becomes the relative magnification to be calculated of both patterns and the phase distance between both graphs becomes a relative angle of rotation.

Title: Error analyzing system
Inventor: MURAMATSU MIDORI
IPC: G06F11/28
Filed: 1989-11-24
Abstract: PURPOSE:To facilitate the analysis of errors by reading some data out of a RAM as an address at output of the tracer contents when a fault occurs and adding the address. CONSTITUTION:When a fault occurs in a CPU 1, a dyagnostic control part 3 informs a service processor SVP 4 of the occurrence of the fault. Then the SVP 4 reads out the contents of a tracer 2 and holds them successively in a register 5. A part of th contents held in the register 5, e.g., the address value of a microinstruction is taken out and used as an address to read the corresponding label information out of a RAM 6. A register 7 holds the contents of the register 5 merged with the label information. Then the contents of the register 7 are printed out. Thus it is possible to obtain a log dump list added with a label serving as an identifier for a microinstruction word. As a result, the errors can be quickly and easily analyzed.
