摘要: A disc apparatus has a cartridge loading/unloading mechanism to perform a loading operation for attaching an optical disc enclosed in a cartridge inserted from an outside to a rotary shaft of a spindle motor and an unloading operation for removing the optical disc from the rotary shaft of the spindle motor and for ejecting the cartridge to the outside. The loading operation of the cartridge loading/unloading mechanism is executed by the rotation of one direction of a load motor. The unloading operation of the cartridge loading/unloading mechanism is executed by the rotation in the reverse direction of the load motor. A drive current of the load motor is turned on or off at a short period, thereby adjusting so as to optimize a drive torque. When an exchangeable optical disc is loaded, a motor is activated, an initialization control is executed during the acceleration, and after a motor rotational speed reached a specific speed, the apparatus enables the writing/reading operations to be executed. When a voice coil motor is driven simultaneously with the spindle motor during the initialization adjustment, the drive current of the spindle motor is limited.

摘要: An optical disk apparatus adapted to a mark edge recording method having a structure such that a data pattern experimentally recorded on an optical disk with one write power is reproduced plural times while changing reproducing conditions (for example, a slice level for binary-coding a reproduced analog signal) and the number of errors is calculated whenever the reproducing process is performed. The thus-structured process is repeated for using a plurality of write powers. An appropriate write power for the optical disk is determined in accordance with the obtained results of the calculations of the number of errors. In a case of a read-only optical disk, a data pattern experimentally and previously recorded on the optical disk is reproduced plural times by changing the reproducing conditions (for example, a slice level for binary-coding a reproduced analog signal), and the number of errors is calculated whenever the reproducing process is performed. In accordance with the obtained results of the calculations of the number of errors, an appropriate reproducing condition for the optical disk is determined.

摘要: An apparatus for reproducing data includes a branch metric computation unit and a plurality of parallel computation units. Each parallel computation unit includes path metric computation units that compute path metric values based on branch metric values. Path metric memories store the path metric values to be used in a next following path metric computation, and reliability computation units compute path reliability. Modified-path generating units generate an inverted path that is inverse to a path indicated by an output of the reliability computation units as having low reliability. If any one of the modified-path generating units generates the inverted path, a corresponding one of the path metric computation units stores a path metric value corresponding to the inverted path in a corresponding one of the path metric memories as a path metric value to be used in a next following path metric computation.

摘要: The present invention realizes stable and more proper data reproduction even when a reproduced signal varies locally due to a noise or includes a steady distortion. In a data reproduction control method and apparatus, and an optical disk unit that adjust sampled values, in sampling a signal reproduced from a recording medium recorded with data, the frequencies of the levels of quantized data are counted, a histogram of the frequencies of the levels is created based on the counting results, and more accurate reproduced data is obtained by means of a distribution of the frequencies of the levels in the histogram.

摘要: An exhaust gas purification apparatus for an internal combustion engine is capable of stably introducing secondary air and heating a catalyst at the same time without increasing an amount of discharge current from the battery. When the internal combustion engine 1 is started, the output terminal A of a generator 10 is electrically connected to the first contact 51 of a switching relay 50 through an output switching circuit 33 and the output terminal A of the generator 10 is electrically isolated from a second contact 52 . As a result, when the internal combustion engine 1 is started, since a current output from the generator 10 is supplied to the motor 8 of a secondary air introduction unit 6 and the heating element 3 of a catalytic converter 4, the power of a battery 20 is consumed only by a plurality of electric loads and is not consumed by the motor 8 and the heating element 3.

摘要: It is to provide a novel molybdenum ion transporter MoTR1 gene responsible for molybdenum transport for the first time in plants, enabling to promote effectively molybdenum absorption from the environment or molybdenum transport in vivo. By QTL analysis of Arabidopsis thaliana accessions Col-0 and Ler, it was found that QTL which dominates Mo concentration in leaves was present on the chromosome No: 2. In the present invention, the region in which the causal gene is present was limited to 172 kb, by a genetic analysis. In the region, the gene At2g25680 having a domain common to sulfate ion transporter, while its function is not revealed was present. Thus, knockout strains of 2 separate lines in which a foreign gene fragment (T-DNA) was introduced at At2g25680 were obtained, Mo concentration in leaves was measured, and MoTR1 gene was identified.
