Filed: 1992-02-27
Abstract: PURPOSE:To simplify the advance inspection of the characteristics of spectral emissivity as to a subject for measurement and enable measurement of radiation temperature at high speed and with high accuracy. CONSTITUTION:A converter 12 computes luminance temperatures (T1, T2) according to spectral radiance (L1, L2) obtained when two different wavelengths (lambda1, lambda2) radiated from a subject S for measurement are detected by a radiation detector 10. A first computing element 14 calculates apparent emissivity epsilon0 by substituting the wavelengths (lambda1, lambda2) and the luminance temperatures (T1, T2) for the following equation: epsilon0=exp[{C2/lambda1-lambda2)}(1/T2-1/T1)] (C2: the second constant of radiation); the computing element 14 then computes the emissivity epsilon1 of the wavelength lambda1 by applying to the calculated apparent emissivity epsilon0 the correlation function between the apparent emissivity epsilon0 and the emissivity epsilon1 at the wavelength lambda1. A second computing part 18 calculates the true temperature using the emissivity epsilon1 computed on the basis of the above equation and the result is displayed in a display 20.

Title: Electrically driven press
Inventor: SHIMIZU MASATO
IPC: B30B15/14
Filed: 1986-04-04
Abstract: PURPOSE:To uniformize the quality of a product and to permit the early discovery of the abnormality of parts by providing functions to detect and store the position of a ram to an electrically driven press and adjusting pressurizing force by changing the set current value of an electric motor. CONSTITUTION:The motor 4 is driven by the ascending signal for setting the origin from the central processing unit 2 when a switch A on an operation panel 1 is turned on. The ram 5 is then raised by the linear motion of a screw mechanism. The central processing unit 2 stops the motor 4 when the projection 5a of the ram 5 presses a limit switch 6a to detect the ascending limit point of the ram 5. The driving is thereafter inverted; therefore, the ram 5 starts descending. The ram descends by as much as the set pulse-component stored in the central processing unit 2, when the motor 4 is stopped. The upper and lower limit pressurizing forces are set and are adjusted by changing the set current of the motor 4 by the pressurizing force. The uniformized quality of working and the reduced expenses by failure are thereby attained and the precise and exact pressing operation is permitted.
