Title: System and device for adding/subtracting absolute value
Inventor: OKAMOTO FUYUKI
IPC: G06F7/50
Filed: 1988-12-22
Abstract: PURPOSE:To perform the addition/subtraction of absolute values at a high speed by calculating previously the carry generating functions in both cases of A<=B and B<A at execution of the subtraction and selecting a proper carry generating function to calculate the carry and the sum of each bit after deciding the difference of value between A and B via a most significant digit carry foresight unit. CONSTITUTION:The carry generating functions are previously obtained in both cases of A<=B and B>A in a subtraction process of the absolute value ¦A - B¦. Then a carry is calculated by a most significant digit carry foresight unit 160 from the most significant of A'' + B + 1 (A'' is complement of 1 of A). If a carry is produced from the most significant, A'' + B + 1 is calculated in a carry foresight system by means of the carry generating function selected in the case of A<=B. In the case no carry is produced from the most significant, A + B'' + 1 (B'' is complement of 1 of B) is calculated by means of the carry generating function selected in the case of B<A. Thus the difference between A and B is always calculated. Thus it is possible to omit an absolute value obtaining process where the complement of an answer 2 is calculated by a conventional absolute value addition/subtraction device. As a result, the addition/subtraction process speed is increased for the absolute value.

Title: Optical repeater
Inventor: NAKATSUGAWA MAKOTO
IPC: H04B10/03
Filed: 1989-12-15
Abstract: PURPOSE:To receive a control signal from a faced line even when a self-line is interrupted by interrupting a data signal and a clock signal to be inputted to an identifying circuit when the self-line is interrupted. CONSTITUTION:When a self-line data signal 1 is interrupted, power is decreased for a signal to be passed through a filter 15 for baud pass and to be outputted from a limiter amplifier 16. In a no-signal detecting circuit 14, this decrease of the power is detected and by disconnecting an analog switch 6-2 and a gate circuit 13, the self-line data signal 1 and a clock signal 17 to be inputted to an identifying circuit 9 are interrupted. Therefore, when the self-line is interrupted, noise is not inputted to a supervisory and control circuit 4 and erroneous detection is not generated in a signal detecting circuit 5-1. Thus, an analog switch 6-1 can normally connect the control signal of the faced line to a command receiver 7 as well.

Abstract: PURPOSE:To arrange data with high density by arranging a sound data and a picture data for background in an area for a real-time file, and arranging the picture data for characters to be in an area for a non real-time file. CONSTITUTION:A first picture data transfer means 120 transfers the picture data en bloc for characters for plural pictures from the non real-time file area of CDI disk 100 to a memory 110, and a sound data transferring means 140 reads out sound data from the area for real-time file and transfers it to a sound generator 130. Also, a second picture data transferring means 150 reads out a prescribed amount of background picture data out of the plural picture data for background and transfers it to the memory 110. A picture constituting means 160 selects one screen amount of picture data for the character, forms a picture data for display in preference to the held picture data for background, and superimposes the character screen with the screen for background. Thus, a high density can be achieved for data arrangement.
