Title: Solution-phase dual hybridization assay for detecting polynucleotide sequences in a test sample
IPC: C07H21/00
Filed: 1986-02-19
Abstract: A dual hybridization assay method for detecting the presence of a particular polynucleotide sequence in a test sample wherein hybridization is accomplished in a solution phase. Two soluble polynucleotide probes are employed which hybridize to mutually exclusive portions of the sequence to be detected. The first, or separation, probe comprises a reactive site for a reaction partner, preferably a binding site (e.g., biotin) for a binding substance (e.g., avidin). After hybridization, the resulting solution is contacted with an immobilized form of the reaction partner whereby dual hybrids comprising the sequence to be detected and the detection and separation probes become immobilized. The immobilized fraction is then separated and the detection probe determined in one of the separated fractions. Preferably, the detection probe is labeled such as with a specifically bindable ligand, e.g., biotin or a hapten, and is detectable by binding of a labeled binding partner, e.g., enzyme-labeled avidin or antibody. The assay method has the advantages of a dual hybridization technique plus the kinetic and manipulative advantages of a solution-phase assay.

Title: Pattern inspection device and method
Inventor: SAKURAI SATOSHI
IPC: G06T7/00
Filed: 1992-01-23
Abstract: PURPOSE:To improve reliability of inspection by obtaining the shape image of an object by performing image processing after acquiring each image individually in reference to first and second target positions of the object to be inspected. CONSTITUTION:First (second) image acquisition means 11A (11B) acquires an image in reference to a first (second) target position p1 (p2) of an object 18 to be inspected and then the image acquisition data D1 (D2) is input by first and second pattern recognition means 12A (12B). The means 12A compares a pattern which changes to the position p1 based on the data D1 and then identifies it and then the means 12B compares it with the reference pattern and then identifies it similarly when the result satisfies the reference value. When both identification results satisfy the reference value, it is compared with a reference data DR by a judgment output means 13 and then the inspection result of the target 18 is output. In this manner, since each image in reference to the positions p1 and p2 is acquired by the means 11A and 11B individually and image processing is performed, a detection error due to an erroneous judgment can be reduced even if the target 18 is accompanied by solder-up state.

Filed: 1986-01-21
Abstract: PURPOSE:To detect an rf signal with high S/N without using a polarized plate by tilting the polarization axis of a straight line polarization incident on a recording medium by 45 deg. to the polarization axis of a polarized beam splitter of an rf signal detection section. CONSTITUTION:A polarized beam splitter 7 is arranged to the rf signal detection optical system of a transmitted light from a recording medium 5 and the polarized direction 10 of the linearly polarized light incident on the recording medium 5 is tilted by 45 deg. to the polarization axis 11 of the beam splitter 7. Then two photodetectors 8, 9 are arranged to the side opposite to the transmission side of the splitter 7. Thus, the constitution above offers the same action in a couple of conventional polarized plates whose polarization axes are perpendicular to each other and they are tilted by 45 deg. respectively to the polarization axes of the linearly polarized light incident on the recording face. Thus, the difference between the two photodetectors is detected as the rf signal by using the polarized beam splitter 7 only.
