Abstract: When a trouble occurs on a transmission line, each station transmits a predetermined frame to the adjacent station. The station which does not receive the frame outputs to the adjacent downstream station a frame instructing that its primary output be looped back to its secondary input. The information transmission trouble is removed by arranging the responses to the frames by the respective stations and the transmission procedure.

Abstract: A pipelined computer includes an instruction cache connected to an instruction prefetch queue for storing a target address and a target instruction, with the address of a branch instruction taken as an index, and a comparator for comparing a predicted target address stored in the instruction cache with a real target address determined upon execution of the branch instruction. When both the target addresses agree in the comparator, the decoding unit and the instruction prefetch queue continue pipeline processing without alteration.

Abstract: The data transmission control system includes a transmitter/receiver data buffer for temporarily storing data transmitted to or from a ring transmission line, a basic clock generating device for generating a basic clock and its phase data to be transmitted in a packet to the next node to synchronize a basic clock of the next node, and a controller for controlling data storage of the data buffer and timing of data transmission to the ring transmission line so as to produce a constant transmission time, thus making it possible to use a circuit switching method in the token ring network.

Abstract: An electric contact capable of terminating a few conductors of different thicknesses. The contact comprises a contacting section provided for contact with a mating contact and a connecting section provided behind the contacting section for connection to a conductor. The connecting section has at least two piercing walls lying in spaced parallel planes perpendicular to the axis of a conductor.

Abstract: A separate operational section for determining the degree of a polynomial is provided to increase the process speed in determining both error locator and evaluator polynomials. When a received word is decoded based on the error location found, the received word is stored in a memory and corrected and output through the designation of the address. The formula ##EQU1## is derived from the error locator equation ##EQU2## and the value of which satisfies .sigma.(.alpha.)=0 is determined to increase the process speed. The decoder and the encoder share part of the hardware to make the system compact.

Abstract: A velocity control unit of a detecting head consists of a differentiation circuit for differentiating a reference velocity signal and feeding it via an analog switch to a first-order lag circuit which generates a feedforward signal. The analog switch is controlled by a constant velocity/deceleration detecting circuit so that it may be turned on in the constant velocity/deceleration period of the head.

Abstract: An off-set signal provided from an off-set detector is stored in a memory. When a head is positioned on a data track, an off-set signal stored in the memory is read out to correct the head position and position the head to the center of the data track, thus effecting accurate reading and writing of data. An off-set generator feeds the servo system with a dummy off-set signal for producing an off-set correction signal, whereby the servo system corrects the off-track of the magnetic head.
