Title: Optical recording and reproducing device
Inventor: IMURA MASAHARU
IPC: G11B7/20
Filed: 1982-11-24
Abstract: PURPOSE:To increase the moving speed of an information recording medium without reducing the life of laser light sources by efficiently superposing straight polarized optical beams which are radiated from two different light sources and intersect each other at right angles by a light superposing means having different optical properties in accordance with the light polarizing directions. CONSTITUTION:The laser light sources 1a, 1b radiate straight polarized optical beams intersecting each other at right angles. Two parallel beams 14, 16 are efficiently superposed by a polarized beam spritter 10 and radiated as an optically superposed beam 18 parallel with an optical axis 12c from a surface 17. The optically superposed beam superposed by the polarized beam splitter 10 passes through a half mirror 14 and forms an optically superposed spot on the information recording surface of the information recording medium 6 by a lens 5, a light focusing means. Since the optically superposed spot is formed by the optical beams from the two light sources, energy about twice the ordinary one can be applied to the information recording medium 6. Therefore, driving the two laser light sources 1a, 1b by a signal supplying device 11 at the recording makes it possible to write data at a speed twice the ordinary one.

Title: Improving amplification of neucleic acid
Inventor: TEIMU KIEFUITSUTSU
IPC: C12Q1/6844
Filed: 1993-08-23
Abstract: The present invention relates to an improved method for the amplification of nucleic acid. The invention is characterized in that ribonucleotides are introduced during amplification that weaken normal basepairing. Preferably the ribonucleotides are inosine-triphosphate nucleotides which partly substitute guanine-triphosphate nucleotides normally present in the amplification reaction mixture. The incorporation of nucleotides, during amplification, that weaken normal base pairing prevents the formation of secondary structures in the amplificate. The efficiency of the amplification is thereby increased. The introduction, during amplification, of nucleotides that weaken normal base pairing also results in an improved sensitivity during detection of the amplified nucleic acid, when the detection method comprises the hybridization of the amplified nucleic acid to a complementary sequence.
