IPC: G01B11/08
Filed: 1988-11-24
Abstract: PURPOSE:To easily and exactly obtain the grain size of the powder which is to be measured of the grain size and is the same material as the material of reference powder from a calculation equation by measuring the transmittance of specific wavelength light with plural liquid dispersions of the reference powder of a known grain size, previously determining the calculation equation for the relations between the transmittance of the dispersions and the grain sizes of the powder and measuring the concn. of the dispersion of the above-mentioned powder to be measured and the transmittance of the same wavelength light. CONSTITUTION:A UV visible spectrophotometer of 200 to 1,100nm measuring wavelength region consisting of two light sources; a deuterium lamp D2 and a halogen lamp W1, is used for the spectrophotometer. The liquid dispersion of the powder is set as a sample side cell Sam in this photometer and only the dispersion medium is set as a reference side cell Ref therein. The transmittance is measured from the attenuation rate of the transmitted light of the case in which the powder particle exists and the case in which the powder particle does not exist. The transmittance of the long wavelength light of >=800nm is measured with the plural liquid dispersions of the reference powder of the known grain size. The experimental equation for the relations between the transmittance of the dispersions and the grain sizes of the powder is determined. The concn. of the powder liquid of the powder which is to be measured and is the same material as the material of the reference powder and the transmittance of the same wavelength are measured. The grain size is calculated from the experimental equation.

Title: Color slurring preventing device
Inventor: KUBOTA YOICHI
IPC: G03G15/16
Filed: 1986-12-17
Abstract: PURPOSE:To obtain a highly accurate servo mechanism and to prevent the generation of a color slurring by using only one oscillator to be a reference for speed control of belt and a drum so as to use it in common. CONSTITUTION:A speed detector S1 for detecting the speed of a belt 1 consists of a rotary encoder or the like having a roll to be brought into contact with the surface of the belt 1. The detecting result of the detector S1 is fed back to a motor M1. A detecting result of a speed detector S2 for detecting the rotational speed of the drum 3 is fed back to a motor M2. The speed on the surface of the drum is detected by the roll contacting with the surface of the drum 3 to prevent the generation of speed variation due to the coupling part of the drum driving motor M2 and the drum 3. The rotational speeds of the belt driving motor M1 and the drum driving motor M2 can be controlled at the same accuracy by setting up the resolution of the speed detector S1 equally to that of the detector S2. Since the moving speeds of the drum 3 and the belt 1 are detected by the speed detectors with the same resolution and controlled by clocks outputted from a common reference oscillator, the servo mechanism with high accuracy can be obtained and the generation of the color slurring can be prevented.
