    摘要： A multi-stage switching network in a telecommunication switching system includes a virtual link frame having fixedly closed virtual switches which are inserted according to the switching system size required by the application range of telephone traffic into a specified intermediate stage of the multi-stage switching network to permit the switching network of large or upper size to be degenerated to a switching network with smaller numbers of stages by degeneratively inducing a partial path structure from the path structure of the upper sized switching network having a great traffic capacity. The switching network with smaller numbers of stages can be incremented to a switching network of larger or upper size according to the switching system size. In either case, the multi-stage switching network can be controlled by the same control circuit and the same control program.

    摘要： A defect detection unit (5), a disc position detection unit (9), and a disc rotation speed detection unit (1) are in a disc control device which includes a repetition control device to control storing to and reading from a memory unit (3) functioning as a learning memory and for varying the number of memory divisions of the memory unit (3) on the basis of detection by the detection units. Components having periodicity apparently due to partial surface runout or partial eccentricity are stored in memory unit (3) by increasing the resolution and microscopic noise components, and noise components having no periodicity are not stored in memory unit (3). This system carries out stable focus tracking control even when disturbances such as device vibration or scratches on a disc are mixed.

    摘要： A key plate examination apparatus and examination method whereby the form of an examined key plate can be recognized accurately and form information of a reference key plate can be compared with the recognized key plate form to determine their conformity rapidly. The form of the examined key plate is recognized by form recognition means, and form information is generated by form information generation means in response to the recognized form of the examined key plate. On the other hand, form information of the key number corresponding to a key number input externally is retrieved by key number retrieval means from a key information memory means storing the key number proper to the reference key plate and its corresponding form information. The form information generated by the form information generation means is compared with the form information retrieved by the key number retrieval means to determine their conformity by determination means. The operator is informed of the determination result of the determination means by communication means.

    摘要： Provided is an orbiting memory capable of suppressing residual deviation even when a phase difference is caused between a signal to be compensated and information stored in a memory to be fed back and a disc device using the orbiting memory. The disc device includes: an adder to which a signal (s10) to be compensated and having a cyclic frequency component such as a control system error signal is inputted; and a feed back signal system for successively updating and storing an output signal of the adder for each cycle in a memory and inputting one-cycle information stored in the memory to the adder. The feed back signal system includes: a filter unit for outputting a signal contained in a learning band which is arbitrarily set among output signals from the adder; the memory for successively updating and storing the output signal of the filter unit; a phase correction unit capable of arbitrarily setting a phase amount when inputting the output of the memory to the adder; and a gain element for multiplying the one-cycle information subjected to the phase correction by the phase correction unit by a value not smaller than 0 and not greater than 1 and inputting the obtained value to the adder.
