Title: Preparation of cholera toxin subunit b
Inventor: ICHIYANAGI TAKUO
IPC: A61K39/106
Filed: 1984-05-17
Abstract: PURPOSE:The titled substance useful for the determination of ganglioside GM1 on the cell membrane and as a vaccine for cholera is obtained from the liquid containing cholera toxin. CONSTITUTION:The anti-cholera toxin antibody is supported on a biochemically inactive, water-insoluble carrier. A liquid containing cholera toxin (CT) is added to the above carrier to effect the reaction of CT with the anti-CT antibody and obtain the CT-anti-CT antibody-water-insoluble carrier composite. The medium component mixed in the CT is removed by washing, and only the CT is eluted to obtain purified CT. The purified CT is converted to the procholeragenoid composed of CTSU-A and the toxoid composed of CTSU-B. The toxoid is separated from the mixture by ultracentrifugal separation. The separation after the centrifugation can be carried out more effectively by putting the high-density solution of cesium chloride, etc. in the centrifuging tube before centrifugation.

Title: Noise reducing circuit
Inventor: TAKAGUCHI TATSUSHI
IPC: H04N9/64
Filed: 1988-04-20
Abstract: PURPOSE:To eliminate even impulsive noise having a large amplitude by processing the output of a band-elimination filter BEF whose gain is 0 for a chrominance subcarrier frequency and that of a band-pass filter BPF which has complementary relations to said filter BEF. CONSTITUTION:A BEF 11 whose gain is 0 for the chrominance subcarrier fre quency and a BPF 12 which has complementary relations to the BEF 11 and permits only a band component having the chrominance subcarrier frequency as the center frequency to pass through are provided, and the noise component having a small amplitude is reduced by the circuit from the BPF 12 to an adder 26, and the impulsive noise having a large amplitude is eliminated by the circuit (a center value selecting circuit 10) from the BEF 11 to a changeover switch SW. When there is not a noise component to be suppressed, a video signal is kept because the BEF 11 and BPF 12 have complementary relations. Thus, only noise components are accurately reduced without causing evils at all.

IPC: G03G9/113
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To lessen the dependence of an electrostatic charge quantity on the environment by using the powder of single phase magnetite for a core material and coating the powder with a resin having high water repellence. SOLUTION: The single phase magnetite is used as a raw material (S1). The resin is diluted or dissolved with a solvent (S2). In such a case, the resin is diluted with a solvent (for example, toluene). Then, the single phase magnetite is put into a fluidized bed device (S3). Next, the resin diluted or dissolved with the solvent is sprayed into a fluidized bed (S4). Then, the single phase magnetite is taken out of the device after the film-forming (S5). A heat treatment (curing) is then executed. The heat treatment of, for example, >=150 deg.C and >=30 minutes as the conditions is executed to thermally cure the resin with which the surface of the single phase magnetite is coated (S6). The electrostatic charge quantity is measured under the specific measurement environment conditions (S7). The surface of the magnetite is thinly coated with the resin having the high water repellence in such a manner to cure the coating, by which the production of the carrier having the excellent environmental characteristic is made possible.
