Title: Controlling method for rolling work by reeling mill
Inventor: SAKURADA KAZUYUKI
IPC: B21B37/78
Filed: 1980-09-01
Abstract: PURPOSE:To prevent the variation in the wall thickness of a pipe, and to improve the yield, by controlling the diameter of the pipe to an aimed size of a rolling pass of a sizing mill, while correcting the expansion of the pipe due to a rolling work of a reeling mill, correspondingly to a thickness deviation caused by a plug mill's rolling work. CONSTITUTION:An arithmetic control unit 21 receives following information; material temperature T measured by a thermometer 20; information about the rolling torque Trq sent from torque meters 16, 16' attached to spindles 22, 22' of rolling rolls 10, 10'; wall thickness tp of a blank pipe measured after a plug mill's rolling pass and before being fed to a reeling mill; and outer diameter DP of the blank pipe. The unit 21 then outputs a reduction control signal DELTAE on the basis of said information to a reduction controller 19 which thereby practices the position control for the rolling rolls 10, 10'. Hereby, the roll gap E of rolling rolls 10, 10' is adjusted correspondingly to a difference (DELTAtA-DELTAto) between an aimed wall thickness reduction DELTAto and the actual reduction DELTAtA in the wall thickness. For DELTAtA-DELTAto>0, the gap E is increased, and for DELTAtA-DELTAto<0, the gap E is decreased, and thereby, the control is practiced so as to always make DELTAtA=DELTAto.

IPC: G01N30/40
Filed: 1982-07-13
Abstract: PURPOSE:To obtain a concentrator which ensures a large concentration along with a wide selectivity by adsorbing several solutes with an overcritical fluid fed to a second trap means from those which have been adsorbed from a solution by a trap means. CONSTITUTION:With vertical movement of a piston 54 and the rotation of a rotary disc 114, a pipeline is changedover to introduced a samle solution to a trap T1 via a pressure converter 11 from a vessel 152. The trap T1 adsorbs solutes while a solvent is sent out as waste. Then, an over critical fluid is delivered by a specified pressure produced with a pump to cause a backflush of the trap T1 so that the solutes will be sent to a hole A of a valve 32. The overcritical fluid flows from the hole A through a hole B and reaches a second trap T2 via a pipeline 158. When entering the trap T2 via a nozzle 160, this flow of the fluid is expanded into an extremely low temperature gas to release all solutes, which are adsorbed with the trap T2. In measuring the quantity of the solutes, the solutes are sent to an analyzer 34 by a backflush of the trap T2 with a carrier gas of a carrier source 164.

Abstract: PURPOSE:To enhance the degree of parallelization of light and to develop the resolving power of a diffraction lattice, by converting the light from an extremely small emitting orifice to parallel luminous flux and arranging a transmission type diffraction lattice in said parallel luminous flux. CONSTITUTION:A pinhole P is matched with the specific part of an extremely weak light emitting object S and a light emitting part to be spectrally diffracted is specified.

This operation is easily performed by mounting the object on an XY movable table and bringing the objective position to the crossing of a reticule by an observation system wherein the diffraction lattice G is pulled off and a detector is replaced with an eyepiece to match the pinhole with the crossing of the reticule. The light from the light emitting object S is set to a spot like or linear light source and converted to parallel luminous flux by the lens L1 having a small numerical aperture having a focus at the position of said light source and said luminous flux is spectrally diffracted by the transmission type diffraction lattice G and subsequently focused by the lens L2 and the wavelength distribution of the luminous intensity at said focus position is detected.
