摘要： An auto-correlation unit for pattern recognition to obtain auto-correlation functions as for sampled signals is disclosed N pieces of sample values X.sub.n (n=0 to N-1)are extracted from a series of the sample values expressed with an accuracy of optional multi-bits and the auto-correlation coefficients of these N pieces of the sample values obtained. The sum of sample values X.sub.n and X.sub.n-.tau. (.tau.=0 to P) are calculated. The squared value (X.sub.n +X.sub.n-.tau.).sup.2 of the added results is previously memorized in a ROM while being addressed by the resultant sum. The auto-correlation coefficients are available by feeding the output (X.sub.n +X.sub.n-.tau.).sup.2 of the ROM and executing calculation as defined by the following equation: ##EQU1##

摘要： Speech recognition executes the final matching operation for each characteristic pattern according to the preliminarily selected order prior to the final matching, where any further calculation in reference to such a characteristic pattern is not executed after a specific condition has been satisfied during the matching calculation, and as result, calculation requirements can be drastically minimized so that the speech recognition can eventually be implemented at higher speed and yet under a sharply reduced cost.

摘要： A transducer access control system for use in a disk recording/reproducing apparatus for moving a transducer a required distance from its present position over a disk in the radial direction thereof, includes a linear motor for driving the transducer, a circuit for generating a distance signal indicative of the required distance for moving the transducer, and a calculator for calculating a half distance which is a half of the required distance. To move the transducer for the required distance D, the linear motor is operated at the velocity controlled in accordance with a reference velocity signal produced from a reference velocity generator. The reference velocity is determined such that, the reference velocity is maintained at a predetermined value during the movement of the transducer in the first half of the required distance, and gradually decreases during the movement of the transducer in the second half of the required distance.

摘要： An apparatus for operating a magneto-optic medium includes a magnetic biasing field developing device for developing a magnetic biasing field which is applied to the magneto-optic medium when the magneto-optic medium erases or records data. Additionally, a neutral-position controller is provided for positioning permanent magnets of the magnetic biasing field developing device in a neutral position with respect to the medium when the magnetic biasing field developing device is switched off. Thereby, the neutral-position controller maintains the medium at the neutral position with respect to the permanent magnets until the magnetic biasing developing device is switched on and the permanent magnets are placed in a field applying position.

摘要： A disk recording checking method in which recording is performed on a disk having radially different recording tracks each divided circumferentially into a plurality of sectors. The method employs a continuous writing device for continuously writing data onto a predetermined number of the sectors, and a continuous checking device for checking the data, while continuously reading the data from the predetermined number of the sectors. The method utilized checks both the number of errors in each code sequence and the total number of errors in each sector to determine if the data in the sector is valid.
