After receiving a time division multiplex signal including a plurality of digital data signals transmitted in accordance with different transmission schemes, the received time division multiplex signal is demodulated by a demodulation circuit, and it is judged by a detection circuit whether each of the demodulated digital data signals is received correctly or not. When it is detected that a digital data signal transmitted by any one of the plurality of different transmission schemes is not received correctly, the relevant digital data signal is replaced by a suitable signal such as a null packet signal which does not affect a correct reception of the remaining digital data signals transmitted by the remaining transmission schemes to form a corrected time division multiplexed signal even if a digital data signal is not received correctly.

Porous hollow fiber membrane having chelate formability and method for recovery of germanium oxide using the porous hollow fiber membrane

The specification relates to an adsorptive material for removing malodorous substances from gases and liquids. The adsorptive material comprises a substrate having macromonomers which are bonded to the substrate and contain functional groups capable of adsorbing polar substances. The adsorptive material is produced by applying to the substrate a mixture of a monosaccharide and the macromonomers and then grafting the macromonomers to the substrate.

Adsorptive materials and process for producing them

There is described a process for producing a filtration membrane that is also capable of adsorbing proteins. The process comprises the steps of subjecting a porous polymeric substrate to a graft polymerization reaction with a polymerizable monomer under exposure to an ultraviolet radiation or an ionizing radiation and thereafter bringing an amino acid into contact with the resulting graft membrane for immobilization. The amino acid is contained in an amount of 0.01-1 millimole per gram of the porous polymeric substrate. The polymerizable monomer to be grafted onto the porous polymeric substrate contains an epoxy group.

Process for producing filtration membranes having amino acids that are

A process for producing a filter membrane capable of simultaneous removal of metallic ions and nonionic materials from process water used in electronics industry, medical field, pharmaceutical industry and nuclear power generation. The membrane is produced by introducing iminodiacetic acid groups to a porous membrane made from polyolefin or a copolymer of an olefin and a halogenated olefin by uv or ionizing radiation initiated graft polymerization.
