Patent number: 10850335Abstract: This cutting insert has: as cutting edges, arcuate cutting edges that are of an arc shape protruding toward an outer circumference side of a distal end. A chisel part is formed at an intersecting ridge line part between the flank faces of the pair of arcuate cutting edges. A round honing is formed on the cutting edge tip of the arcuate cutting edge at least in a range where a radial angle is 30° or less. A curvature radius of the round honing in a cross section perpendicular to the edge length direction of the arcuate cutting edge is 20 to 40 ?m. A chisel angle formed between the distal end part of the arcuate cutting edge and a chisel edge of the chisel part is 150° to 170° as seen in an insert front view.Type: GrantFiled: October 19, 2017Date of Patent: December 1, 2020Assignee: MITSUBISHI HITACHI TOOL ENGINEERING, LTD.Inventors: Yasuhiro Kiuchi, Yoshiyuki Kobayashi, Takao Nakamigawa

Patent number: 4353142Abstract: A floor mop or the like is shown including a mop removably, replaceably mounted to a mop carrier, for instance using conventional Velcro hook and fleece fasteners. The mop carrier is pivotally mounted to a mop handle via a bearing arrangement that includes sleeves on the carrier and handle, pinned together with a pivot pin that is non-rotatable relative to the carrier but which provides for a limited degree of rotation of the mop carrier relative to the mop handle upon overcoming a moderate degree of friction between the pivot pin and mop handle bearing barrel that results from a snut fit between specially contoured surfaces of these two members.Type: GrantFiled: June 9, 1980Date of Patent: October 12, 1982Assignee: Duskin Franchise Kabushiki KaishaInventors: Masanobu Nishiyama, Yasuhiro Kiuchi
