Abstract: PURPOSE:To make it possible to obtain an area at an instant tracing is finished and to make memory capacity the minimum, by computing the increments or decrements of the area at every instant in parallel with the tracing of the figure, and accumulating said increments or decrements. CONSTITUTION:From a point A on a figure whose area is to be obtained, tracing is performed clockwise in the sequence of ABC. During the tracing, vertical segments to an X axis are computed and accumulated (the increment of X during this period is positive). The area, when the ABC is traced, becomes ABCl. Then the vertical segments to the reference line during the tracing period for CDE are computed and accumulated. The increment during this period is negative. Therefore the figure CDEl is negative. The area, when the tracing is performed to a point E, is ABCDE. The same procedure is performed for EFGA. When the tracing of ABCDEFGA is finally finished, the desired area is obtained.

Title: Method for constituting by-pass of loop transmission system
Inventor: YOSHINO KAZUSHI
IPC: G06F13/00
Filed: 1984-06-15
Abstract: PURPOSE:To expand the transmission range of information and to shorten a time related to the detection of a failure by sending a check signal to a closed loop constituted of continuous transmission control pairs adjacently arranged on the loop transmission line to detect abnormality and changing the number of transmission control pairs constituting the closed loop. CONSTITUTION:To detect the position of a failure, checking is started from a loop constituting a by-pass at a transmission control pair separated from the self-transmission control pair by kXn (k=1-n) sections on the loop transmission line and the check loop is narrowed successively from a far position to a near position. One cycle of a loop including a by-pass separated by n sections is checked at first, and if the checking is unsuccessful, the distance is successively narrowed like n-1, n-2-1. When a normal by-pass is not detected even if the sectional distance goes to ''1'', a by-pass is formed in the self-transmission control pair and the checking range is expanded from 2n to n+1 sections. When a normal by-pass is detected, the by-pass constituted in the self-transmission control pair is released and message transmission to the loop is restarted.

Title: All wave rectifier circuit
Inventor: NAGANO KATSUMI
IPC: H02M7/12
Filed: 1979-09-25
Abstract: PURPOSE: To accomplish high accuracy with a simple constitution by a method wherein an emitter voltage of a transistor, having an emitter and a collector connected to a voltage supply terminal through a resistor, is compared with a rectified input voltage.  
     CONSTITUTION: When an emitter voltage of a transistor Tr3 is high against an input voltage Vin, a Tr91 collector current is smaller than a Tr92 collector current, so a Tr81 collector current, which is on the input side of a current mirror circuit, becomes smaller and in response to this a Tr82 collector current is also functions to the attenuating direction, thereby causing an emitter voltage to drop. In contrast with this, when the input voltage is higher than the Tr emitter voltage, the collector current functions inversely to the above, the emitter voltage increases and a stabilized condition is attained at a point when this voltage becomes equivalent to the input voltage to be rectified Vin. In this way, with a relatively simple constitution, rectifying accuracy can be increased.
