    摘要: The computer system includes a host system, a recording medium, and a digital signal decoder connected to the host system and the recording medium. The digital signal decoder receives M-bit data and generates an N-bit code word from the M-bit data. The number of consecutive bits of 1 in the code word is not larger than a first predetermined number K, and the number of consecutive bits of 0 is not larger than a second predetermined number L. When data is recorded/reproduced by a method such as NRZI (Non-Return to Zero Inverted), or the like, there is a defect in that the number of transitions of data is larger in a code with a high data encoding rate, and the run length of zero is long thereby increasing the data decoding error rate with the recording/reproducing of data. In the digital signal decoder according to the present invention, any code word includes at most 3 consecutive bits of 1, and at most 11 consecutive bits of 0, so that the data decoding error rate can be reduced.

    摘要: A magnetic disk drive is provided capable of reducing a processing load even in a mode of, for example, reproduction during recording. In one embodiment, a magnetic disk drive includes a storage unit for storing certificate information that relates to the magnetic disk drive and corresponds to a root key of a certification organization. The certificate information is used on the host side to perform authentication processing of the magnetic disk drive.

    摘要: Provided is a plant cultivation device that improves cultivation efficiency and usability. A plant cultivation device comprises: a rack unit provided with cultivation racks on which cultivation units accommodating plants are stored as culture medium units; and a conveying device which moves along a horizontal movement path defined by a guide rail, and performs transport of the culture medium units and loading/unloading of the culture medium units to/from the cultivation racks. Multiple cultivation racks constitute a cultivation rack row, in which the cultivation racks are arranged at multiple levels in an up-down direction. The rack unit comprises: a cultivation storage constituted of multiple cultivation rack rows; and a loading/unloading station having a stock rack row, in which the holding frames of cultivation units not accommodating plants are stored as empty units. The transport device performs loading/unloading of the holding frames to/from the stock rack row.

    摘要: The invention flexibly limits a terminal able to play content and prevents unfair utilization of the content. In one embodiment, an identifier proper to each terminal device is allocated to discriminate each playback equipment. The identifier of a terminal which is allowed to play the content is registered to this license. When the content is played, authentication is performed between the terminal device as a license transfer destination and a memory device as a license transfer source. The identifier of the terminal device itself is transmitted to the memory device as a transfer source at an authenticating time. The memory device collates the identifier sent from the terminal device with an identifier registered to the license. If these identifiers are the same identifier, the memory device transfers the license to the terminal device. In contrast to this, if these identifiers are different identifiers, the memory device stops the transfer of the license.
