Title: Hiv and material for removing its related substance
Inventor: MOTOMURA TADAHIRO
IPC: B01D15/00
Filed: 1994-04-28
Abstract: PURPOSE:To easily and selectively remove HIV and its related substances with high accuracy from a soln., such as blood or plasma prepn., contg. protein, etc., by depositing sulfuric acid groups substantially in the form of a salt on the pore surfaces of a porous substance. CONSTITUTION:The blood is filtered by the porous substance deposited with the sulfuric acid groups substantially in the form of the salt. The porous substance is a porous membrane of an average pore size of 0.1 to 1mum consisting of a hydrophobic polymer and is deposited with a polysulfuric acid compd. on the surface of this porous membrane. This polysulfuric acid compd. is not particularly limited, insofar as this compd. is the one having plurl sulfric acids in the molecule. Such polysulfuric acid compd. includes sulfated polysaccharides, such as sulfated dextran, sulfated cellulose and curdlan sulfate and polymers and copolymers of sulfonated monomers, such as sulfoethyl acrylate, vinyl sulfate and styrene sulfonate. As a result, the HIV and its related substances included in the plasma are adsorbed away simultaneously when the plasma is separated.

Filed: 1979-07-18
Abstract: PURPOSE:To widen the width of erasing effect, by erasing at least twice the information track desired for erasion recorded on the recording media by means of different scanning locus, which is biased toward orthogonal direction to the track. CONSTITUTION:At the tracking control of the information track desired for erasion, the tracking signal S2 corresponding to the shape of distortion is stored corresponding to the lengthwise direction of track to the waveform memory circuit 13 by means of the waveform memory command signal S5 and read out corresponding to the lengthwise position of track.

IPC: H03H9/00
Filed: 1984-05-10
Abstract: PURPOSE:To obtain a miniature multi-mold filter which has a wide band characteristics and can be used in a range of 500kHz-1MHz, by attaching a set of electrodes made of a constant elastic metal with a space decided by the pass band width to the lengthwise counter surfaces of a rectangular piezoelectric ceramics having the residual polarization in the lengthwise direction and utilizing the vertical effect. CONSTITUTION:Constant elastic metallic electrodes (elinvar, etc.) 2, 2' and 2'' are fixed on both sides of a rectangular piezoelectric ceramics 1 having a residual polarization 3 in the lengthwise direction and utilizing the vertical effect by means of an adhesive like solder, etc. An input signal of a pass band frequency is impressed between input side electrodes 5 and 5' of such a filter from an oscillator 4. Thus the vibrations of a thickness slip mode are generated between input side electrodes 2 and 2'', and the vibration energy is enclosed under electrodes by a mass load effect of the electrodes. In the same way, the vibration energy is also enclosed under an area between output side electrodes 2' and 2''. Thus this filter can be used in a wide band of frequencies owing to use of the piezoelectric ceramics having a large electric-mechanical coupling coefficient as a piezoelectric material.
