Title: Apparatus and method for measuring thickness of metal on rolling mill
Inventor: JIYON KUREIBIRU
IPC: G01B15/02
Filed: 1993-07-13
Abstract: PURPOSE: To measure the thickness of a material being rolled. CONSTITUTION: This device and method are for measuring the thickness of a moving sheet 106 having an alloy composition that fluctuates longitudinally, typically a metal. The measurements are made by measuring using a length- absorbing-filter radiation detector 1 10 the spectrum energy of a radiation beam that passes through the material perpendicularly without being absorbed by the material. The length absorbing filter separates the radiation into a plurality of waveforms and measures the strength of the wavelengths. Outputs showing these measurements are output to a processing device 118, which determines the thickness of the material on the basis of the transmission ratio measured for each energy band measured and of the absorption coefficients of elements in the material. The result is utilized in controlling a rolling mill in real time through on-line feedback.

Then, a p-side electrode 9 is grounded; a voltage of V (V<0) is applied to an n-side electrode 8 in such a way that the p-n-p transistor becomes an active region. During this process, a collector current flowing in the laser diode is decided by a voltage to be applied to the electrode 10 of the n-type GaAs current-blocking layer 5 as the base electrode. Thereby, it impossible to control an optical output by means of the voltage to be applied to the electrode on the n-type GaAs current-blocking layer; a drive circuit and the like are simplified.
