摘要： PURPOSE:To accurately measure the shapes of the citrus fruits and to eliminate the overlooking of a discoloring defective part by detecting the outward shape or discoloring defect part according to a video obtained by photographing continuously a fruit which is being conveyed and rotated by a roller conveyor in a slanting arrangement. CONSTITUTION:Roller shafts of rollers 18 and 18 of the transfer conveyor 16 of the inspecting device 12 which conveys the citrus fruits are arranged slantingly at an angle theta to a conveyance side from the horizontal direction. The citrus fruits 10 are rolled in the conveyance direction by the rotation of the rollers 18 and 18 and spun and moved, but when the rollers 18 and 18 are rotated at different rotating speeds, the fruits 10 are twisted and spun on the rollers 18 and 18. Here, the rollers 18 and 18 are flocked in mutually different states and twist spinning is possible without making their rotating speeds different. Further, the outer peripheral surfaces of the rollers 18 and 18 and the other peripheral surfaces of the flocking are colored in complementary relation with the skin color of the fruits 10 and a television camera 22 and a video processor 24 are used to extract only the color components of the skin of the fruits 10 and their outward shapes, thereby making classifications by classes and grades.

摘要： PURPOSE:To easily separate and remove foreign matter by photodetecting an X-ray image of a raw fish tool by a photodetecting device by utilizing an electroluminescence phenomenon, converting its photodetection image plane into an electric signal and operating buckets of a bucket conveyor. CONSTITUTION:Raw fish shucked short-necked clams 14 fed from a supply hopper 16 are fed in the buckets 24 by a specific amount continuously and conveyed intermittently under an X-ray irradiating device 32. The raw fish short-necked clamps 14 in the buckets 24 are irradiated with X rays from the X-ray irradiating device 32 in synchronism with the intermittent conveyance cycles of the conveyor 18. The X-ray image of the shucked short-necked clams 14 is photodetected by the photodetecting device 36, whose electroluminescence panel 38 photodetects it with high sensitivity and high brightness. The photodetection signal is converted by a converting device 42 into the electric signal and the conveyor 24 for the shucked short-necked clams 14 containing foreign matter is rotated down like a keyboard through the operation of a support roller 50 according the electric signal, so that the foreign matter is easily stacked in a defective hopper 54 and separated.

摘要： PROBLEM TO BE SOLVED: To obtain high dust collecting performance with high operation voltage and to weaken radiated electromagnetic wave noise even if spark is generated. SOLUTION: This electrostatic air cleaner is provided with an electrode system of a charging part 10 composed of a discharge wire 11 and a flat plate 12 opposed thereto and an electrode system of a dust collecting part 20 composed of a high voltage impressed flat plate 21 and a dust collecting plate 22 and spark discharging current is suppressed by the resistance of the electrodes theirselves of the discharging part and the dust collecting part. The intense of the radiated electromagnetic wave noise is remarkably suppressed and generating sound of discharge is made small preferably by imparting a distributed resistant component equal to or above π times a characteristic impedance per unit length to a characteristic impedance settled by the electrostatic capacity and the coefficient of self-induction of the electrode system by each electrode. And since the high voltage operation is enabled, dust collecting performance is improved.
