摘要:
The radioactive iodine compound of this invention or an intermediate for preparing the compound is represented by the following formula (I): ##STR1## wherein R is H or .sup.125 I. The radioactive compound can readily introduce a radioactive isotope element such as .sup.125 I into an antibody molecule without damaging the activity of the antibody molecule. Therefore, the compound can preferably be used to label an antibody of immunoradiometric assay, and allow a higher degree of measurement sensitivity.

A hybridoma producing a monoclonal antibody recognizing the C-terminus of human brain natriuretic peptide (hBNP) was cultivated in a medium or the abdominal cavity of a mouse to recover the monoclonal antibody from the medium or ascites accumulated in the abdominal cavity. An immunoassay for hBNP was established using the monoclonal antibody. The immunoassay for hBNP of the invention is so sensitive that the minimum detection limit is 1 pg/ml and can therefore determine the hBNP level in blood plasma directly, without the extraction of hBNP from blood plasma. It is useful for diagnosing diseases such as hypertension and the like, and states of the heart, kidney, and the like by using the increase/decrease of the hBNP level as an index.

摘要:
In copying apparatus having a magnification ratio varying device, wherein a photosensitive member in motion is exposed to an optical image of an original by slit exposing to form an electrostatic latent image thereon and the original scanning velocity is varied in accordance with the magnification ratio selected, it is necessary to effect registration of the forward end of the image of an original with the leading end of a photosensitive sheet or a transfer-printing sheet. The above-mentioned registration is effected by delivering a copy sheet after lapse of a predetermined period of time following the production of a detection signal by a detector, the above-mentioned predetermined period of time being varied in conformity with the selected one of magnification ratios.

摘要:
A multi-mode copying machine capable of effecting copying in accordance with a sheet mode copying system and a book mode copying system is provided with an original feed apparatus having means for guiding conveyor belts to deflect away from an original irradiation position in their travel, the conveyor belts being adapted to transport an original in sheet form. Further, the original feed apparatus has means for transporting an original in sheet form exactly at a predetermined rate in the sheet mode copying system and for transporting the original without deformation or breakage while being fed at a high rate in the book mode copying system.
摘要:
A touch panel including an upper substrate (4A) consisting of a soft film having an upper resistor film (51) and a lower substrate of a hard plate having a lower resistor film, which are bonded together to face each other. The touch panel provides a detection output representing the position of contact between the upper resistor film (51) and the lower resistor film as two-dimensional coordinate values. Either the upper resistor film (51) or the lower resistor film or both are of a comb shape having a plurality of resistive lines with a common connector (41) at one end.
