Patent number: 7267860Abstract: A topsheet 10 of an absorbent article is a nonwoven fabric having a plurality of heat fusion joints 3 formed by embossing. Fibers constituting the nonwoven fabric protrude in the thickness direction of the nonwoven fabric between the joints 3 to form a plurality of protrusions 4a and 4b on both the upper and the lower sides of the nonwoven fabric.

Publication number: 20060234228Abstract: Test nucleic acids are identified by the steps of: synthesizing multiple nucleic acids that comprise nucleotide sequences complementary to different regions of a test nucleic acid; and comparing the dissociation curve of a mixture of the synthesized nucleic acids. The dissociation curve of a mixture of nucleic acids shows a waveform pattern that is unique to the test nucleic acid. Many types of nucleic acids can be efficiently identified using simple reactions. The multiple types of nucleic acids that are necessary for analysis can be easily synthesized by using a primer complex that anneals to multiple regions of the test nucleic acid.Type: ApplicationFiled: May 20, 2003Publication date: October 19, 2006Inventors: Joji Oshima, Ken Nemoto
