    摘要: 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.

    摘要: 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.

    摘要: 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.
