IPC: G01J3/28
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To measure the influence of stray light and to improve the accuracy and linearity of a spectrometer by blocking the specific wavelength of a light source spectrum. SOLUTION: A collimation lens 102 converts light discharged from a light source 100 to parallel beams. A filter 104, a shutter 106, and a sample 108 enter and exit a light path by computer control. A focusing lens 110 focuses light at a slit 112. The light is subjected to spectrum scattering by a diffraction grating 114 and is focused at a photodiode array 116. A specific wavelength is blocked by filters 104, 118, and 120. Compensation intensity spectrum is measured by positioning the filter 104 at a specific position. Namely, a first compensation measurement is performed without a sample 108 by using the filter 104. A second compensation measurement is performed by use of both the filter 104 and the sample 108. By multiplying the compensation measurement values by a coefficient, the quantity of stray light hitting against the array 116 is estimated.

Title: Device for ejecting rolling material
Inventor: MATSUO TATSURO
IPC: C21D9/00
Filed: 1993-02-02
Abstract: PURPOSE:To reduce the variation of time between rolling materials in a rolling line and to improve the productivity by reducing the time between the rolling materials. CONSTITUTION:By a control part composed of a host computer and a program controller, ejecting movement is controlled as follows. When a photoelectric tube arranged near the outlet of a heating furnace (i.e., at a position shorter than the length of the rolling material in the distance to a rolling mill) detects the tip part of the preceding material, the host computer calculates the rolling time of the preceding material, and based on this, the ejector is started to drive at the earlier time than the ordinary time and thereafter, lock time (t) in an ejecting roller is calculated. The program controller receives this lock time (t) value and after detecting the rear end of the preceding material bitten to the rolling mill with the photoelectric tube, the ejecting roller is locked by the time (t). During this locking condition, the ejector lays the following material on the ejecting roller. When the locking time (t) passes, the ejecting roller is rotated to feed the following material to the rolling line. By this control, the time between the rolling materials is not affected to the rolling time of the preceding material and the ejecting preparing time.
