  • Patent number: 8961910
    Abstract: There is provided a technology for decreasing copper and tungsten contained in tantalum-containing wastes, and recovering a high-purity tantalum. The present invention is a tantalum recovery method for recovering tantalum from a tantalum-containing waste, the method comprising subjecting the tantalum-containing waste to an acid treatment in an oxidizing atmosphere, thereafter to a roasting treatment and an alkali treatment, and further comprising carrying out a magnetic separation treatment before the acid treatment to thereby separate a tantalum-containing material in the tantalum-containing waste. This is particularly a suitable recovery method for recovering tantalum from wastes containing a relatively large amount of copper and tungsten such as discarded substrates such as printed wiring boards.

  • Publication number: 20150044690
    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.

  • Publication number: 20150044763
    Abstract: FRET measurement uses a FRET probe that includes a probe element X labeled with a donor fluorescent substance and a probe element Y labeled with 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. A test sample as a measuring object in FRET measurement contains a test object about which it is unknown whether or not it has an approaching/binding property of allowing the probe element X and the probe element Y to approach to each other or bind together or a separating property of separating from each other the probe element X and the probe element Y that are in a state where they adjoin each other or bind together. A plurality of sets of a fluorescence lifetime ?sample and a ratiometry Rsample obtained by this measurement are used to judge whether or not the test object has the approaching/binding property or the separating property.

    Abstract: A first and a second surface of a latch for a seat permit sliding passage of the latch relative to a front leg of a striker, upon contact of the front leg with either of the first and second surfaces. A third surface in a containing space of the latch stops the latch by contacting the front leg. The third surface is arranged such that a rear leg of the striker is brought in alignment with a lock groove of the latch upon contact of the front leg with the third surface. The latch can be guided along the second surface when the second surface contacts the front leg, so that the second surface slides on and past the front leg. By continuously unfolding the seat back upwards until the third surface contacts the front leg, the seat back can be set to a design reference position.
