摘要： A technology is provided to improve tamper resistance in encrypting data to be secured and inputting/outputting the data between a recording device and a host device. When the recording device issues an input/output command to a storage device to input/output data to be secured, the recording device attaches an ID to the command to identify to which cryptographic input/output processing the command belongs. Upon reception of a sequence command, the storage device receives the command if its ID has been allocated and the command is verified to have been issued in the correct sequence. The sequence ID is used to identify a process system while appropriately managing the steps of executing commands.

摘要： Embodiments of the present invention provide a simplified authentication transaction for reconnecting a storage device to a host apparatus that has completed authentication in the past. According to one embodiment, an authentication log is recorded in the host. Plural units of this log information are recorded in the storage device. At the time of transferring a content decryption key and usage rules between the host and the storage device, the decryption key and usage rules are recorded into the host as a log for the transfer. The used authentication log is recorded into the storage device as RAPDI. If RAPDI indicates the authentication log in the simplified authentication transaction, recovery transaction is permitted. The host device deletes/invalidates or holds the log for the transfer in accordance with non-permission/permission. In the case of permission, the key and usage rules are recovered by using a log for the transfer prior to the simplified authentication transaction.

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 spring-actuated electromagnetic brake includes a noise-suppressing device for suppressing a striking noise emitted when an armature is attracted onto a field to release the brake when an electromagnetic coil is excited to magnetize the field. The noise-suppressing device is comprised of a plurality of hemispherical elastic members each disposed in one of recesses formed in one of two opposed surfaces of the field and the armature. When the brake is in the engaged state, a hemispherical surface of each elastic member partially projects from the recess and is in contact with the other of the two opposed surface. When subjected to a compressive force or pressure applied from the armature, the hemispherical elastic member undergoes elastic deformation as a whole and does not produce any locally concentrated elastic deformation. The hemispherical elastic member is highly durable and is able to greatly suppress the striking noise generated when the brake is released.

摘要： In a laser beam machine tool, the problems of power losses, misalignment, high cost, and other problems associated with moving laser heads are eliminated by using a five-axis table in which a biaxial work holder, capable of rotating and tilting a workpiece is mounted on a three-axis table mechanism. In the three-axis table mechanism, an X-axis table is supported on linear motion bearings in overlapping relationship on a Y-axis table, which is, in turn, supported on linear motion bearings on a vertically movable Z-axis table, which is also supported in linear motion bearings. The X-axis, Y-axis and Z-axis tables are driven by servo motors through ball screws so that backlash is avoided.
