IPC: B01J20/32

Abstract: A method for the removal and concentration of desired ions from a source solution which may contain larger concentrations of other ions including H⁺ comprises bringing the source solution into contact with a compound comprising a polytetraalkylammonium and/or polytrialkylamine containing ligand covalently bonded through an organic spacer silicon grouping to a solid inorganic support. The polytetraalkylammonium and/or polytrialkylamine portion(s) of the compound has an affinity for the desired ions to forma complex thereby removing the desired ions from the source solution. The desired ions are removed from the compound by contacting the compound with a much smaller volume of a receiving solution having a greater affinity for the desired ions than does the polytetraalkylammonium and/or polytrialkylamine ligand portion of the compound. The concentrated ions thus removed may be recovered by known methods. The process is useful in removing desired or unwanted ions from water streams and in the treatment of waste streams. The invention is also drawn to the polytetraalkylammonium and polytrialkylamine containing ligands covalently bonded through a spacer grouping to a hydrophilic inorganic solid support material.

Abstract: An amplifying circuit of the invention comprises: a high frequency amplifying circuit (3) for amplifying high frequency; a low frequency amplifying circuit (4) for amplifying a low frequency; input filters (6, 8, 10, 11) which are provided on the input side of the respective amplifying circuits (3, 4) so as to pass the frequency components thereof; output filters (7, 9) having the same characteristics as those of the input filters; and an adding circuit (5) for adding outputs of the output filters. Therefore, an output dynamic range of the whole amplifying circuit is equal to the sum of the dynamic ranges of the respective amplifying circuits, so that a large output which is not distorted even if a sound volume is raised is derived. By providing a matching filter (12) on the input side of the low frequency amplifying circuit (4), even if the low frequency side output filter (9) which needs a large coil is omitted, the frequency characteristics of the output of the adding circuit (5) can be made flat and the amplifying circuit of a small size and a less distortion can be realized.

Correction coefficeints of the sensor outputs are computed from the peak voltages and center voltages, and the sensor outputs are compensated based on these correction coefficients. A fine displacement is then computed by an inverse trigonometric function from the two corrected signals, and a displacement signal is output by adding the coarse displacement to the fine displacement.
