Abstract: PROBLEM TO BE SOLVED: To make transmission quality uniform at each channel by performing A/D conversion and hierarchical separation to a transmission analog signal and performing batch optical transmission by modulating and multiplexing the carrier wave of a correspondent frequency for each hierarchy. SOLUTION: A digital electric signal passed through an A/D converter 101 is divided into plural hierarchies corresponding to the degree of importance consisting of source data by a hierarchical separation part 102 and modulated by 1st-4th digital modulation circuits 1031-1034 at a modulation part 103 for modulating the modulating carrier wave of a frequency corresponding to each hierarchy by a hierarchical signal. This modulated signal is passed through a multiplexer part 104 and an electric/optic converting part 105 and a batch signal is transmitted. In this case, the carrier signal of a low frequency is modulated by the modulation part 103 corresponding to the degree of importance consisting of a transmission signal and the transmission quality can be made uniform at low cost for each channel having the different levels of waveform degradation and distortion corresponding to bands.

Abstract: PURPOSE:To transfer a minute magnetic object at a high speed by utilizing magnetic gradient leaked out of a magnetic circuit gap to mvoe a magnetic body electromagnetically. CONSTITUTION:A coil (electric wire) 3 is wound on a yoke 2. When a current is applied to the coil (electric wire) 3, magnetic flux is produced in a gap 1 and leaked magnetic flux is produced in areas 4 and 5 apart from the gap 1. A magnetic body or a compound magnetic body 5 is transferred due to the leaked magnetic flux in the direction of 4 or 1.
