Publication number: 20100074069Abstract: There are provided an optical disk device and tilt correction processing method for performing recording/reproduction by rapidly acquiring an optimal tilt correction value for an optical disk having a plurality of recording/reproducing layers. In an optical disk device capable of recording or reproducing information by irradiating a laser beam to each of a plurality of recording/reproducing layers of an optical disk, the tilt value is stepwise set within a predetermined range at a predetermined radius position of the recording/reproducing layer located at the farthest distance from the laser beam irradiation side so that an optimal tilt correction value can be obtained from the quadratic function by the method of least squares of the jitter or the like obtained from the disk. By applying the optimal tilt value obtained to the other recording/reproducing layer, it is possible to start recording or reproduction in a short time.Type: ApplicationFiled: December 2, 2009Publication date: March 25, 2010Applicant: Hitachi, Ltd.Inventors: Koji Iijima, Motoyuki Suzuki, Junji Nakajima

Publication number: 20080264048Abstract: An inlet chamber 40 and outlet chamber 50 for exhaust gas are integrated as an inflow/outflow section 80, and a first post treatment device 10 equipped with a DPF 13 at its central portion and second post-treatment device 20 equipped with a urea DeNOx catalyst 23 on its outer periphery side are integrated as a catalyst installation section 70. The catalyst installation section 70, the inflow/outflow section 80, and a communication chamber forming section 30 are provided separately and detachably from one another, and the catalyst installation section 70 is made installable in a reversible manner. As a result, by reversing the catalyst installation section 70, it is possible to easily reverse the DPF 13 without having to extract it from the central part. Further, since the urea DeNOx catalyst 23 is reversed simultaneously, it is possible to change the direction in which the exhaust gas flows therein, thereby enabling to prevent unbalanced deterioration of the urea DeNOx catalyst 23.Type: ApplicationFiled: November 24, 2005Publication date: October 30, 2008Applicant: KOMATSU LTD.Inventors: Toshihiko Nishiyama, Koji Iijima

Patent number: 5689611Abstract: A method and an apparatus by which a panorama image is produced with a high degree of accuracy from an image signal are disclosed. An image signal produced by a CCD imaging element is recorded onto a video tape by way of a camera signal processing circuit, a recording signal processing circuit, a recording/reproduction amplifier and so forth. Meanwhile, a microcomputer calculates of a motion vector of an image from the output of a motion vector detector to which the image signal from the CCD imaging element is inputted, and controls a video subcode processor so that motion vector information may be recorded onto the video tape. The motion vector information is reproduced from the video tape together with the image signal, and a plurality of images are formed from the thus reproduced image signal and joined together in accordance with the motion vector information to produce a panorama image.Type: GrantFiled: January 5, 1996Date of Patent: November 18, 1997Assignee: Sony CorporationInventors: Masashi Ohta, Hiroshi Kobayashi, Tsuneo Sekiya, Toshimichi Hamada, Kyoko Fukuda, Koji Iijima

Patent number: 5168363Abstract: A video signal processing apparatus for performing editing of video signals includes a memory into which one field or one frame of a moving picture video signal from a video camera is written and a crossfading circuit, wherein a still picture of the video signal is written in the memory at a selected time or at a time the video camera stops operation. Thereafter, when the video camera resumes operation, the contents of the memory are read out, so that the real moving picture video signal being currently provided by the video camera and the previous still picture video signal read out from the memory are crossfaded. The video signal processing apparatus can also cooperate with a video tape recorder for storing in the memory a still picture derived from the video tape recorder, so that when the video camera starts its operation, the real moving picture video signal produced by the video camera and a still picture video signal from the memory are crossfaded.Type: GrantFiled: October 15, 1990Date of Patent: December 1, 1992Assignee: Sony CorporationInventors: Masaaki Kojima, Kazuo Yoshino, Teruhiko Kori, Takao Takahashi, Koji Iijima

Patent number: 4777537Abstract: Described is a method and a recording apparatus whereby audio and video signals can be recorded on a plurality of recording tracks on the same recording medium. A series of temporarily consecutive audio signals can be recorded across a plurality of tracks. On at least the audio track, information signals including the leading track number, the next following track number and the number of the video track bearing the corresponding video signals, are recorded. The track number data of the information signals on these audio tracks are written in corresponding positions of a digital, table memory. These control code data are recorded on a predetermined control track on the recording medium such that a series of desired audio signals and the corresponding video signals can be selectively reproduced smoothly and promptly by first reading the control track and then reproducing the audio and video tracks in accordance with the control code data information.Type: GrantFiled: October 10, 1986Date of Patent: October 11, 1988Assignee: Sony CorporationInventors: Katsuhiko Ueno, Takayuki Sasaki, Koji Iijima, Masaaki Arai
