  • Patent number: 9307639
    Abstract: Present invention provides an electro-deposited copper foil having the equivalent low-profile surface as in a conventional low-profile electro-deposited copper foil and extremely large mechanical strength and a method for manufacturing the same. The electro-deposited copper foil is formed by depositing fine copper crystal grains having a small deviation of grain-diameter. The electro-deposited copper foil has a low-profile and glossy surface and has extremely large mechanical strength expressed by a tensile strength as received of 70 kgf/mm2 to 100 kgf/mm2 and has a tensile strength after heating (180° C. for 60 minutes) corresponding to 85% or more of the tensile strength as received. The electro-deposited copper foil is manufactured by electrolysis using a sulfuric acid base copper electrolytic solution containing a compound composed of a benzene ring having a sulfo group bonded thereto, a sulfonate of an active sulfur compound and a polymer of a quaternary ammonium salt having a cyclic structure.

  • Patent number: 9291563
    Abstract: FRET measurement uses a FRET probe that includes a probe element X containing a donor fluorescent substance and a probe element Y containing an acceptor fluorescent substance and enables FRET to occur when the probe element X and the probe element Y approach to each other or bind together. The modulation frequency of laser light with which the FRET probe is irradiated is adjusted to an optimum modulation frequency that maximizes a difference between the phase difference of donor fluorescence emitted from the donor fluorescent substance with respect to intensity modulation of the laser light at the time when FRET occurs and the phase difference of donor fluorescence emitted from the donor fluorescent substance with respect to intensity modulation of the laser light at the time when FRET does not occur.
