Filed: 1987-09-21
Abstract: PURPOSE:To eliminate the lacking of an original music sound signal and to prevent mal-detection by providing an amplitude modulator and a detector to designate a duplication inhibition depending on the presence/absence of an amplitude-modulated signal. CONSTITUTION:A music sound signal inhibiting the duplication is subjected to a prescribed amplitude modulation in an amplitude modulator 1, and transmitted to a transmission medium 2. In case of reproducing said signal to duplicate it in a duplication medium 5, that the prescribed amplitude modulation is applied is detected by the detector 3, a duplicator 4 is stopped, and thus the duplication is inhibited. Since the duplication inhibition is designated depending on the presence/absence of the amplitude modulation, any lacking of an original music sound signal does not occur. Also, by making the modulation factor sufficiently small, the variation in the amplitude can be made below a level that can be noticed by a human being. By this selecting a modulation signal suitably, a mal-detection can be prevented.

Title: Clock signal distribution circuit
Inventor: NOMURA MASAHIRO
IPC: G06F1/10
Filed: 1993-09-24
Abstract: PURPOSE:To set a clock skew to be small or to improve driving performance by shorting output terminals for the respective stages of buffers or at every several stages in plural hierarchies. CONSTITUTION:The outputs of the buffers 101-105, 111-114, 121-124, 131-134 and 141-144 (simplex invertors) constituting tree structure are shorted by shorting wirings 161-164 and 171-194. Since the distribution of a clock makes, loads to be equal by tree structure and the output terminals are shorted in the respective stages, the skews occurring in the respective stages are small and the occurred skew can efficiently be reduced by shorting. The invertor in an initial stage is made small and the invertor in a final stage is made large so that the input capacity and the output resistances of the respective buffers become small. Thus, capacity to be charged/discharged through the output resistances and wiring resistances can be made small and therefore driving performance can be made large.
