Abstract: PURPOSE:To shorten data retrieving time by protrusively providing a magnetic drum where a positional information signal accompanying each data signal is recorded on a rotary shaft on a nearly same plane as a voice coil and disposing a magnetic sensor for reading the positional information signal so that it may be opposed to the drum. CONSTITUTION:By energizing the voice coil 10 which is positioned in the mag netic field of a magnet 12, a head 9 is linearly displaced in proportion to an energizing current.

Title: Duplex loop transmission system
Inventor: HIRASAWA SHIGEKI
IPC: H04L12/42
Filed: 1989-02-03
Abstract: PURPOSE:To confine influence due to the delay of transmission of a node only on a loop on one side by automatically selecting a type with the node corresponding to the quantity of input/output relating to the node. CONSTITUTION:Each node calculates the ratio of the total quantity of data arriving at the node to the quantity of data addressed to its own node for constant time. The type is automatically converted from a one-side input/output type to a both-side input/output type when the value of the above ratio exceeds a value (a) decided in advance, and from the both-side input/output type to the one-side input/output type when it is less than a value (b). A node receiving data corrects a state table at every transmission of the data from the node whose type is changed. Also, each node, when transmitted data being returned as it is without being received, corrects the value of the state table of a destination node of the data from the one of the both-side input/output type to that of the one-side input/output type, and from the one of the one-side input/output type to that in error. In such a manner, the delay in the transmission between significant nodes with the large quantity of input/output can be released.
