  • Patent number: 7426027
    Abstract: A small object identifying device and its identifying method according to which a large number of small objects can be identified. In one embodiment, the device includes a dispersion region section which disperses a large quantity of several kinds of small objects which are labeled by a combination of the presence/absence or measure of label elements of several kinds. A measuring device distributes and associates kinds of said label elements to two or more measurement points and measures the presence/absence or the measure of said label elements of the kinds which have been associated with respective measurement points. An identifying section associates the measurement results measured at each measurement point to thereby identify said small objects.

  • Patent number: 6723237
    Abstract: The invention relates to a concentration device using magnetic particles and a method therefor aimed at performing concentration of a large volume of liquid efficiently and reliably with a simple structure and on a small device scale. The construction involves having: a liquid suction passage in which liquid can pass through only in a suction direction; a liquid discharge passage in which liquid can pass through only in a discharge direction; a magnetic force device which can exert a magnetic field from outside of the liquid passage on at least one liquid passage thereof or remove the magnetic field, and which can separate magnetic particles having directly or indirectly captured a target substance suspended in the liquid by having the magnetic particles adhere to the inner wall of the liquid passage; a storage section communicated with each liquid passage, for storing the sucked liquid; and a pressure adjustment device for sucking and discharging the liquid by adjusting the pressure in the storage section.
