摘要： PURPOSE:To find the light diffusion characteristic of a face to be measured, which has been averaged over a definite area in all directions. CONSTITUTION:A ring-shaped light source 3 is arranged in parallel with a face 1 to be measured, a photodetector 2 at a field angle theta is arranged coaxially with the light source 3 so as to be directed to the face 1 to be measured, and the diffusion characteristic of the face 1 to be measured is measured on the basis of the ratio of the radius of the light source 3 to the height from the face 1 to be measured of the light source 3 or to the height from the face 1 to be measured of the phtodetector 2 or on the basis of a light-receiving intensity measured by changing the visual field angle theta. In addition, when the measuring method is used to continuously measure a change in the roughness of a face, a prescribed angle constant alpha is used, and the light-receiving intensity is found on the basis of the radius of the light source 3, the height from the face 1 to be measured of the light source 3, the height from the face 1 to be measured of the photodetector 2 and a magnitude relationship between the value of an expression decided by the theta and the alpha.

摘要： PURPOSE:To highly efficiently pickle a hot-rolled steel sheet utilizing cavitation by injecting a laminar high-pressure pickling soln. on the entire region of the steel sheet in its cross direction and impressing a continuous ultrasonic wave with the pickling soln. as a medium. CONSTITUTION:A laminar high-pressure pickling soln. is injected on the surface of a hot-rolled steel sheet 1 introduced into a pickling device 13 at a specified angle. The content of the laminar high-pressure pickling soln. column 12a is transmitted, and a focused ultrasonic wave 8 of 20-100kHz frequency is impressed on the sheet 1 surface. The sheet is efficiently pickled by the impact force and chemical action of the high-pressure pickling soln. and the chemical reaction accelerating action and impact force of cavitation. A plate wave is generated by the injected strong ultrasonic wave in the forward and backward rolling directions of the sheet 1. A boundary layer between the sheet 1 surface and the pickling soln. supplied by the soln. column 12a is broken by the plate wave, and pickling is accelerated.

摘要： PURPOSE:To efficiently and effectively descale and pickle a steel sheet by focusing an ultrasonic energy at a specified angle to the steel sheet surface to increase its density and causing cavitation. CONSTITUTION:A hot-rolled steel sheet 1 is predistorted in the lower yield region by a scale breaker 10 and then conveyed into a pickling layer 13 by a roll 11 through an inlet 9. The sheet 1 is kept at a fixed level between rolls 12 and 12. A strong focused ultrasonic wave 21 of 20-100kHz frequency is injected from an oscillator 20 set in a pickling soln. 13 onto the upper and lower surfaces of the sheet 1. The ultrasonic wave 21 is line-focused on the sheet 1 surface by a cylindrical acoustic lens 3 to cover the entire region of the sheet 1 in its cross direction. Cavitation is caused by the ultrasonic wave 21, and the sheet is efficiently pickled. Meanwhile, the boundary layer between the sheet 1 surface and the pickling soln. 13 is broken by the produced plate wave, and pickling is accelerated.

摘要： PURPOSE:To measure accurate film thickness even when the refractive index and property of a base material change by calculating the thickness of a thin film from the phase angle cosine relation among reflected light beams from thin films classified by wavelengths and the base material. CONSTITUTION:Light beams emitted by homogeneous light sources 20 and 21 which differ in wavelength are passed through a half-mirror body 22 and a polarizer 23 alternately through shutters 26 and 27 to illuminate the surface of a sample 24 which has thin films on the base at an angle phi0. Light beams reflected by the thin films and base of the sample 24, on the other hand, are branched into three light beams by optical flats 29a-29c, transmitted through respective analyzers 31a-31c which have fixed transmission azimuth angles, and sent to respective photoelectric converters (not shown in figure). The outputs of the respective photoelectric converters are inputted by the wavelengths, the phase angle cosines of the respective reflected light beams from the thin films and base are found by the wavelengths from the inputted output signals, and the thicknesses of the films are calculated from the relation among the phase angle cosines.

摘要： PURPOSE:To decrease the transmission quantity of radiation heat and to measure exactly the flow rate of gas by controlling the quantity of electricity to be applied to each heating element in such a manner that the temp. of an outside radiation shielding body is made equal to the temp. of an inside heating element probe. CONSTITUTION:A heater 11 and the 1st temp. measuring sensor 12 are contained in the heating element probe 1. The outside radiation shielding body 2 is so installed as to provide the double construction to enclose partially the probe 1. The heater 21 and the 2nd temp. measuring sensor 22 are contained therein. The electric energy to be applied to each heating element is so controlled by using a controller 3 that the temp. T2 of the body 2 is made equal to the temp. T1 of the probe 1. The transmission quantity of radiation heat is decreased by the above-mentioned method. The exact measurement of the flow rate of the gas to be measured is made possible even if the temp. of said gas is as high as >=400 deg.C.

摘要： PURPOSE:To prevent the deterioration of the measurement precision of ellipso- parameters even if an object to be measured tilts a little, in the measurement of the ellipso-parameters. CONSTITUTION:The polarized light is radiated with a prescribed angel phi to an object to be measured 13, and the reflected light 18 of the object 13 is separated to four different polarized light components by using an optical system including a beam splitter 19. Two ellipso-parameters as the final targets are obtained by resolving the simultaneous equations consisting of four equations having the variation rate of the intensity reflection rate/intensity transmission rate in the case where the reflected light 18 is separated into the reflection light 20a and the transmission light 20b by the beam slitter 19 from four separated light intensity I1, I2, I3 and I4, the value related to the light intensity of the reflected light 18 and two ellipso-parameters, as four variables.
