Abstract: Technique to provide an abrasive regeneration method which, from a used abrasive, 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, zirconium oxide and cerium 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, an abrasive recovery step (C) for recovering the separated and concentrated abrasive, and a second concentration step (D) for filter-treating the concentrated abrasive.

Abstract: 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.
