Patent number: 9028179Abstract: Chips are segmented to have a desired width and the chip controllability is improved and the tool rigidity is improved. A drilling tool is provided that includes: a tool body; a chip discharge groove formed at the outer periphery of the tool body; at least one sub-groove formed at an inner face facing the front side in the tool rotation direction T of the chip discharge groove; a rake face; a tip end flank face; and a cutting edge formed at a ridge line at which the tip end flank face intersects with the rake face. The plurality of rake faces form a step-like shape having at least one step section. The drilling tool is configured so that the turnup section of the sub-groove is turned up in a different direction from the direction along which the turnup section of the chip discharge groove is turned up.Type: GrantFiled: November 18, 2011Date of Patent: May 12, 2015Assignee: Tungaloy CorporationInventors: Kengo Wada, Koji Nisikawa

Publication number: 20130181465Abstract: After a scratch 160 or similar defect formed on the readout surface of an optical disc is nearly completely removed by grinding and polishing the readout surface with surface with a grinding/polishing agent or similar compound, the readout surface is coated with a coating agent 170 made of a transparent resin or similar material. In this process, a significant change in the thickness of the optical disc before and after the restoration can be prevented by controlling the grind/polishing and coating processes so that the decrease in the thickness due to the grinding/polishing is nearly equal to the increase in the thickness due to the application of the coating agent 170. Therefore, even a Blu-ray Disc or similar optical disc having only a small distance from the surface to the information record layer can be restored many times.Type: ApplicationFiled: January 17, 2012Publication date: July 18, 2013Applicant: ELM INC.Inventors: Takakazu MIYAHARA, Terumasa MIYAHARA, Kengo WADA

Patent number: 5513818Abstract: A tape winding apparatus, for winding a certain length of magnetic tape in a cassette, comprises a detection unit and a cassette distributor. The detection unit detects the existence of holes on the cassette, which are regarded as information used in winding the magnetic tape. The winding operation of the winding station is controlled by the information received from the detection unit. If the information set by a controller and the information detected by the detection unit do not match, the cassette is regarded as defective and is distributed to the appropriate location by the cassette distributor.Type: GrantFiled: March 14, 1994Date of Patent: May 7, 1996Assignee: Otari, Inc.Inventors: Kengo Wada, Yuji Sakuma, Shinichi Nomura
