Patent number: 9489975Abstract: An optical disk device which quickly detects that a transparent disk is loaded is provided. When an optical disk is loaded, a drive controller of an optical disk device drives a spindle motor and checks existence of an optical disk based on a driving result. In addition, the drive controller drives an optical pickup to apply a focus control, to detect whether or not focusing is possible. When it is determined from the driving result that there is an optical disk and that focus is not possible, the drive controller judges that the optical disk (D) is a transparent disk.Type: GrantFiled: July 31, 2009Date of Patent: November 8, 2016Assignee: Almedio Inc.Inventor: Tatsuya Murata

Publication number: 20130022734Abstract: In the method for producing a medical pressure-sensitive adhesive tape or sheet of the invention, a water dispersion-type copolymer solution having a specific composition is used. Therefore, the problem caused by high thixotropy can be eliminated and a pressure-sensitive adhesive layer can be relatively easily formed on a porous substrate by a direct method. In addition, when the medical pressure-sensitive adhesive tape or sheet obtained by the method of the invention is attached to the skin surface, skin adhesion and tube fixing are excellent and at the same time, irritation to skin is low.Type: ApplicationFiled: July 20, 2012Publication date: January 24, 2013Applicant: NITTO DENKO CORPORATIONInventors: Tatsuya MURATA, Noriyuki KIKUTA, Atsushi HAMADA, Tomonari NAITO, Nobuaki MARUOKA

Patent number: 8185919Abstract: An optical disk device which highly precisely positions a disk tray in an ejection position is provided. A controller of an optical disk device drives the disk tray from a storage position toward an exposed position. When a position immediately before the ejection position is detected by a detecting switch, the velocity is reduced, to allow the disk tray to contact a mechanical stopper, for positioning. The controller measures a movement time to the position immediately before the ejection position, and adjusts the drive voltage to increase or decrease the drive voltage for contact with the mechanical stopper according to the measured time.Type: GrantFiled: August 4, 2009Date of Patent: May 22, 2012Assignee: TEAC CorporationInventor: Tatsuya Murata

Patent number: 8050161Abstract: An optical disk drive capable of reproducing data even when warpage is present in an optical disk. A system controller of the optical disk drive reproduces data by setting a maximum speed in accordance with the type of an optical disk, an amount of side-to-side runout, or the like. In the meantime, when a read error arises as a result of trial reproduction being performed at an outer radius of the disk at startup, warpage is determined to be present in the optical disk, and a limitation on the maximum speed is raised. The rotational speed is set to allowable maximum speed of the optical disk drive, and warpage is corrected by means of centrifugal force. When reproduction becomes impracticable for reasons of meandering of a tack, or the like, during the course of reproduction of data, the rotational speed is decreased, to thus perform a retry.Type: GrantFiled: March 26, 2008Date of Patent: November 1, 2011Assignee: TEAC CorporationInventor: Tatsuya Murata

Patent number: 8036081Abstract: An optical disk processing system having a recording unit and a printing unit is provided. The optical disk processing system comprises a printing unit and a recording unit. A drive controller of the recording unit rotationally drives a loaded optical disk (D) and detects whether or not a rotational speed is reduced during acceleration. When the rotational speed is reduced, it is judged that a stick-slip has occurred and loading of a plurality of the optical disks (D) is detected.Type: GrantFiled: June 5, 2009Date of Patent: October 11, 2011Assignee: TEAC CorporationInventor: Tatsuya Murata

Patent number: 7983130Abstract: An optical disk processing system having a recording unit and a printing unit is provided. An optical disk processing system comprises a printing unit and a recording unit. An optical disk is driven with a low torque and then with a high torque. Based on reaching times until target rotational speeds are reached when the optical disk is driven with the low torque and the high torque, a type of the optical disk is judged. Loading of a plurality of optical disks is detected when the judgment results for low torque and for high torque do not match.Type: GrantFiled: June 5, 2009Date of Patent: July 19, 2011Assignee: TEAC CorporationInventor: Tatsuya Murata

Patent number: 7957235Abstract: A disk drive controls the rotational speed of a disk to an appropriate value. A system controller of the drive stores data read from a disk and read-ahead data into buffer memory. A time interval ti at which the buffer memory becomes full is measured, and the time interval ti is compared with a predetermined lower limit value t1 and a predetermined upper limit value t2. When a relationship of ti>t2 stands, rotational speed is increased. When a relationship of ti<t1 stands, control is performed in such a way that the rotational speed is decreased so as to achieve t1?ti?t2.Type: GrantFiled: March 31, 2008Date of Patent: June 7, 2011Assignee: TEAC CorporationInventor: Tatsuya Murata

Patent number: 7944788Abstract: An optical disk drive capable of reproducing data even when defects, such as flaws or stains, are present in the disk. A system controller of an optical disk drive reproduces data by setting the maximum speed in accordance with the type of an optical disk, an amount of side-to-side runout, and the like. When reproduction of data becomes impracticable for reasons of meandering of a track, or the like, in the middle of reproduction of data, the rotational speed is decreased, and a retry is performed. However, when reproduction of data becomes impracticable for reasons of flaws or stains, the rotational speed is reversely increased, and a retry is performed.Type: GrantFiled: March 11, 2008Date of Patent: May 17, 2011Assignee: TEAC CorporationInventor: Tatsuya Murata
