    摘要： Technique to provide an abrasive regeneration method which, from a used abrasive slurry, can recover an abrasive by an efficient method and can thereafter obtain a high-purity regenerated abrasive by a simple method. This abrasive regeneration method uses an abrasive comprising at least one type of abrasive selected from diamond, boron nitride, silicon carbide, alumina, alumina zirconia and zirconium oxide. The abrasive regeneration involves a slurry recovery step (A) for recovering an abrasive slurry discharged from a polishing machine, a separation and concentration step (B) for adding an alkaline earth metal salt as an inorganic salt to the recovered abrasive slurry to aggregate the abrasive, and separating and concentrating the abrasive from a mother liquor, and an abrasive recovery step (C) for recovering the separated and concentrated abrasive.

    摘要： A medical imaging system includes an X-ray Talbot imaging apparatus and an image processing apparatus. The X-ray Talbot imaging apparatus includes a controller which generates reconstructed image(s) including at least a differential phase image from image signals of an imaged subject. The image processing apparatus measures the thickness of cartilage in the joint in the differential phase image or an image generated from the differential phase image, by reference to at least one of i) an edge of a bone in the joint identified in a reconstructed image or an image generated from the reconstructed image and ii) an edge of the cartilage identified in the differential phase image or the image generated from the differential phase image.

    摘要： A paper feed apparatus is capable of correcting the skew of a sheet irrespective of a differential conveyance distance. The paper feed apparatus is provided with a first large volume paper feed apparatus 100A having a control unit 130 which performs first correction control to correct the skew of a sheet by controlling a first conveyance unit 110 and forming a loop of the sheet P before a paper stop rollers 110d, and also performs second correction control to correct the skew of a sheet by controlling a second conveyance unit 120 and forming a loop of the sheet before a paper stop rollers 110d. In this case, the control unit 130 controls the first conveyance unit 110 and the second conveyance unit 120 in order that the skew correcting ability of the second correction control becomes greater than the skew correcting ability of the first correction control.

    摘要： A glossiness inspection device includes an illumination device that emits irradiation light to a glossiness detection target and a light receiving device that receives reflected light of the irradiation light reflected by the glossiness detection target and outputs a light reception detection signal according to an amount of the received light. A dimmer of the device adjusts an amount of the irradiation light, and a detection signal adjuster of the device adjusts a gain for amplifying the light reception detection signal. An irradiation position controller of the device selectively irradiates a first gloss region and a second gloss region of a correction plate with the irradiation light. A hardware processor of the device adjusts at least one of the amount of the irradiation light, an offset of the detection signal adjuster, a characteristic straight line for calculating a glossiness, or a calculated glossiness.
