Title: Controlling device of thickness of forge-welded pipe
Inventor: SATO TAKASHI
IPC: B21B37/18
Filed: 1985-03-25
Abstract: PURPOSE:To control the thickness of a forge-welded pipe so that the thickness is uniform even if the thickness of a flat plate varies by inserting a tapered plug into a material pipe at the final stand of a forge-welder and adjusting the inserting position of the plug. CONSTITUTION:The tapered plug 11 is inserted into the material pipe in a caliber of the final stand 2-n of the forge-welder and the insertion position of the plug 11 is adjusted. A main controller 14 compares an initially set position of the plug 11 with an actually detected position, generates a speed criterion in accordance with the compared deviation, controls a thyristor-Leonard device 12, and adjusts the position of the plug 11. The deviation between the set thickness and an actual thickness of the flat plate is tracked on other hand. The position correcting value of the plug 11 is calculated to correct the thickness of the pipe in accordance with the deviation being larger than a specified value in the final stand 2-n; the speed criterion according to the deviation is inputted into the thyristor-Leonard device 12 to adjust the position of the plug 11.

Title: Damage monitoring method for compressor and device therefor
Inventor: OTSUKI YASUHIKO
IPC: F04B49/10
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To find out a damage on a blade and the like in an early stage by calculating a compressor efficiency, calculating a reduced efficiency by a correction efficiency found out from a compressor inlet temperature in a rated condition and a correction efficiency found out from an inlet guide blade opening in the rated condition, and monitoring the reduced efficiency. SOLUTION: In an efficiency monitor of a compressor, a compressor efficiency ηreal is calculated from a compressor pressure ratio, a compressor delivery temperature, a compressor inlet temperature CTIM, and a specific heat ratio of an operating fluid. The compressor efficiency is reduced to a rated condition by ηconv =ηreal -ΔηCTIM-ΔηIGV ηconv is a reduced efficiency, ΔηCTIM is a correction efficiency by an IGV opening. In a monitor device, the ηconv reduced in the rated condition is monitored, and it is judged that a moving blade of the compressor or a part of a stationary blade is broken when the value is reduced more than a setting value. It is thus possible to find out a damage on a blade and the like of a compressor automatically and precisely.

Filed: 1982-04-09
Abstract: PURPOSE:To read picture information with the most suitable scanning line density in response to the state of picture of an original, by performing the output control of a line sensor at the reverse motion in response to the result of discrimination of the state of picture original obtained at the forward motion. CONSTITUTION:At the forward movement of the scanner, the scanning to detect the picture condition of an original 2 is executed, the picture information read at the scanning is processed and stored in a memory. At the reversing of the scanner, each line information is read out sequentially in the reverse direction from the storage from the memory and the discrimination of the fine line section is discriminated. In response to the result of discrimination, the sub- scanning speed of the scanner is lowered for lines where the change in black and white is frequent, and the sub-scanning speed of the scanner is quickened for the thick line part where the change in black and white is less. Thus, the picture information is read efficiently with the most suitable scanning line density in response to the picture state of the original.
