Thus each of LD 14 to 16 is assigned for the video signals of only 20 channels. Under such conditions, the effective light modulation degree mue is 20% or less as long as the light modulation degree is set at 6.3% or less per channel. Thus no clipping distortion is generated. Meanwhile the VOD signals are also transmitted via an exclusive LD 18. The optical outputs of the LD 14 to 18 are synthesized by the 3dB optical couplers 22 to 24 and finally multiplexed into a single optical signal LF20 ABCV that is transmitted via a single optical fiber 2.

Abstract: PURPOSE:To form a bale where the forming pressure of a bale is increased, the density is not varied, and the volume reduction ratio is large by increasing the width of an upper roll among the roller groups forming a compression chamber to extrude the compressed bale. CONSTITUTION:The substance to be compressed is fed over the whole width of a compression chamber 9 from a carrying conveyor 35 through a connection port 34. When the diameter of a bale 12 is expanded in the compression chamber 9, and the approximately whole circumference is connected to rollers 7, 8, a part of the non-compressed substance is scraped into the connection port 34 from a surface part of the bale 12 by a roller 7-1. The frontage capable of pulling the substance by the roller 8 becomes higher by increasing the diameter of the roller 8 above inner pressure plates 2, 3, and the range to be brought into contact with the raised non-compressed substance is increased. The non- compressed substance which is scraped and raised is successively pushed over the surface layer part of the bale 12 without staying at the connection port 34. The bale 12 is fixed to a housing 33 on the side where the inner width is narrower, and discharged without delay by the pushing force of the housing 33 and the self-weight of the bale 12.
