Abstract: PROBLEM TO BE SOLVED: To detect the target sequence by hybridizing a single strand chain oligonucleotide containing a fluorescent label with a target sequence in the presence of a double-strand DNA-binding protein under heating and subsequently converting the single-strand chain into the double strand chain form to change the fluorescent polarization.  
     SOLUTION: A probe or signal primer comprising a single-strand oligonucleotide containing a fluorescent label labeled with fluorescein, eosin, rhodamine, etc., is hybridized with a target nucleic acid sequence in the presence of a double-strand DNA-binding protein (e.g. polymerase) at a temperature of approximately 45-75°C. The hybridized single-strand oligonucleotide is elongated on the target nucleic acid sequence. The amplified single-strand oligonucleotide is converted into the double-strand chain form. Thus, the target nucleic acid sequence is detected by the fluorescent polarization change accompanied by the conversion.

IPC: B23K26/02
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To enable positioning with high accuracy without preliminary working. SOLUTION: According to this laser beam machine, when positioning an object to be worked, the object is irradiated by a laser beam for working, which has been adjusted to an energy density by which the object is not worked, and fluorescence generating in an irradiating position is detected by a photoelectric detecting means. According to its information, the object is positioned. Therefore, in this machine, preliminary working is unnecessary.

Abstract: PURPOSE: To accurately record and reproduce information and to make an optical system small in size and thin in structure by integrally forming a light splitting means with a photodetector means and providing a light reflection means guiding split light to the photodetector means. CONSTITUTION: After irradiating light a1 emitted from a light source 1 is transmitted through a diffraction means 2 ass zero-th order diffracted light, it is condensed by a condensing means 3 so as to form a fine spot on a recording carrier 4. After the reflected light a2 reflected by the carrier 4 is reversely transmitted through the means 3 again, it is polarized as 1st order transmitted light a3 by the means 2. The diffracted light a3 is reflected by the light reflection means 7 arranged in parallel to the light splitting means 5 and the photodetector means 6 integrally formed. Furthermore, the reflected light a5 is made incident on the means 6. Based on the incident amount and the incident position of the split light a4 on the means 6 at such a time, the error of the focus position of the means 3 or the entire pickup and the carrier 4 is detected.  Then, the information is recorded and reproduced while performing focus controlling by controlling the relative positions between the means 3 and the carrier 4, or the entire optical pickup and the carrier 4 by a mechanism detecting the error amount of a tracking position.
