Abstract: PURPOSE: To provide an optical fiber testing method capable of simply discriminating whether the undulation of the waveform displayed by OTDR is caused by the fluctuations of a Rayleigh's scattering coefficient or a back scattering collection rate or the fluctuations of light loss. CONSTITUTION: A light pulse 21a is allowed to be incident on one end of an optical fiber 20 and the light intensity waveform of back scattering light 21b is observed. A light pulse 22a is allowed to be incident on the other end of the optical fiber 20 and the light intensity waveform of back scattering light 22b is observed. A formula wherein a back scattering collection rate and transmission loss are separated can be formed by the addition and subtraction of two light intensity waveforms and the characteristics of the optical fiber can be simply evaluated.

Abstract: PURPOSE:To prevent the drop-out of an original image on copying paper by changing the reference position of the image by the signal to detect the use and non-use of an automatic sheet original feeder so that the image is formed in the specified position. CONSTITUTION:The optical path of a sensor 3 is interrupted and a signal is fed to an image processing part 10 when an original 1 is placed on an imposing base 2 in the case of taking a copy by an automatic original circulator RDF. The image read-out position from a line memory is changed to the read out from just before 2.5mm in the part 10. The original 1 is set apart respectively by 2.5mm from the front and rear index plates when the RDF operates and the original 1 is fed to the prescribed position of a platen 7. The original picture image is resolved by an optical system 8 to the picture elements converted photoelectrically by a photodetector 9 and is stored in the line memory of the part 10 with the deviation by as much as the position corresponding to the image deviation from the reference position of the index plates. Since the image is read out earlier by 2.5mm in the part 10 by the signal from the sensor 3, the exposing on a drum 14 by the laser light of a laser modulating part 12 is moved by 2.5mm in the main scanning direction, by which the formation of the copy image is made possible in the same position where RDF is not used.

IPC: G01N23/18
Filed: 1992-08-17
Abstract: PURPOSE:To obtain a method for discriminating quality of tuna by which the distribution of fat in the body of a frozen tuna and the presence/absence and, if present, location of a parasite in the body of the tuna can be discriminated without manual aid. CONSTITUTION:The tomogram of a frozen tuna is taken by projecting X rays upon the part of the tuna near its anus in the crossing direction from an X-ray CT device 10. An arithmetic processor 38 calculates the distribution of fat in the body of the tuna from each area ratio of each specific CT-value area against the CT-value area of the body by extracting those indicating the body of the tuna from among CT values obtained from the tomogram and, at the same time, specific CT value areas decided by dividing the extracted CT values in corresponding to the fat content in the body of the tuna. Then the processor 38 discriminates the fat distribution in the body of the tuna from each calculated area ratio. At the time of discriminating the presence/absence of a parasite, the presence of a nonextracted CT value in the extracted specific area is confirmed on the picture.
