Title: Manufacture of virus antigen
Inventor: EDOWAADO JIEIMUZU SUTOTSUTO
IPC: C12N7/08
Filed: 1981-06-30
Abstract: Antigens specific to respiratory syncytial virus are produced on the surface of cells by: (1) culturing in vitro cells derived from a human or animal mucosa, (2) inoculating the cultured cells with respiratory syncytial virus, and (3) selecting virally infected cells from the culture. The resulting cells or the viral antigen(s) when partially or completely isolated from the cells have immunological and diagnostic uses in respect of infection by respiratory syncytial virus and may be used to isolate viral antibodies. A specific cell strain NM7 produced by this method from bovine nasal mucosal cells has respiratory syncytial virus antigens on its surface and its corresponding, uninfected cell strain NM5 can be infected similarly.

Title: Purification of valeraldehyde
Inventor: MIYAZAWA CHIHIRO
IPC: C07C45/50
Filed: 1990-04-17
Abstract: PURPOSE:To industrially advantageously purify valeraldehyde in stably performing continuous operation while suppressing valeraldehyde attaining high boiling point by distilling a reacted solution of valeraldehyde by keeping a specific amount of butene fraction in a bottom solution in a distilling purification of the reacted solution of valeraldehyde. CONSTITUTION:In obtaining valeraldehyde by hydroformylation of butene fraction, a valeraldehyde-containing reaction product is supplied into a distillation tower and the distillation is operated with keeping concentration of butene fraction in the bottom solution at >=2wt.% and at <=150 deg.C bottom temperature, then distillate containing unreacted butene fraction as a principal component is distilled, thus a fresh solution containing valeraldehyde is obtained from the tower bottom to purify valeraldehyde. Thereby, temperature of the tower bottom is lowered, suppressing the valeraldehyde from attaining high boiling point and variation of the tower bottom temperature is able to be had extremely small. Furthermore, the system is stably performed in continuous operation.

Filed: 1996-04-23
Abstract: PROBLEM TO BE SOLVED: To make it possible to attach a thin adhesive tape which has a single- layer adhesive layer to a die pad section of a lead frame with high accuracy by adjusting a relative position between a base film and the die pad section and then attaching the adhesive layer to the die pad section. SOLUTION: A lead frame is supplied to an attachment position and then an adhesive layer 12 is supplied to the attachment position as it is kept attached to a base film 10, that is, the base film 10 is used as a carrier of the adhesive layer 12. By setting the ratio of a tape feeding speed to a lead frame carrying speed at a specified value, a relative positon between the tape and the lead frame is adjusted.

Filed: 1996-04-23
Abstract: PROBLEM TO BE SOLVED: To precisely identify the locus of a corresponding point from a multi view point input image by changing a detecting condition that an identifying means uses and generating parametric image data expressing a corresponding point with a luminescent spot identified every individual point. SOLUTION: A corresponding point locus judging part 12 scans the multi view point image in a memory 11 to search the image of the luminescent spot with a linear locus. This search is controlled by a coefficient sent from a coefficient control part 13. A memory 14 stores the coefficient of the locus of the detected luminescent spot (n) and the grey level of the luminescent spot in a file 40. Judgement at the locus judging part 12 uses a threshold value, which is controlled by a threshold value control part 15. A memory 16 holds a position of the locus of the corresponding point in the image and a detected condition. A data output part 17 outputs the coefficient of the locus of the corresponding point. A data input part 110 inputs parametric data from the file 40.  Then a corresponding point locus interpolation part 31 interpolates the locus of the corresponding point of a data input part 30 from the position of the actual view point of an observer to generate an image seen from the view point.
