  • Publication number: 20090137428
    Abstract: A probe-immobilized carrier for detecting a target substance is manufactured such that a spot is prevented from being contaminated with another spot and a probe is prevented from nonspecifically adsorbing a background area in the manufacture of the probe-immobilized carrier and nonspecific adsorption cannot be occurred even after the formation of an array. A substrate containing a reactive group for immobilizing a probe thereon is used and the steps of: (i) supplying a liquid droplet containing a probe on the substrate; (ii) inactivating a reactive group existing in an area other than a supplying area of the substrate, and (iii) removing an unreacted probe existing in the supplied liquid droplet are carried out.

  • Publication number: 20070264656
    Abstract: A probe-immobilized carrier in which a probe capable of specifically binding to a target is immobilized on a substrate is manufactured by a method comprising the steps of: (1) coating the substrate with a reactive substance having a reactive group for immobilizing the probe on the substrate; (2) applying the probe to a surface of the substrate coated with the reactive substance; (3) immobilizing the applied probe on the substrate; and (4) applying an inactivating compound capable of inactivating the probe to a probe-immobilized area on the substrate to inactivate an unreacted probe remaining on the substrate in the probe-immobilized area.

  • Patent number: 6424532
    Abstract: A memory module 10 is fitted with a “cover and heat sink” 5 having a U-shape in cross section in such a manner that the memory module 10 is inserted into a U-shaped deep recess of the “cover and heat sink” 5, and all packaged memory ICs 3 and the other components 2 mounted on each face of a printed circuit board 1 are covered by the “cover and heat sink” 5, with a silicone grease 6 being filled between the “cover and heat sink” 5 and the packaged memory ICs 3. The heat generated in each packaged memory IC 3 is conducted to the “cover and heat sink” 5 through the silicone grease 6, and the heat is radiated from the surface of the “cover and heat sink” 5 having a large surface area. In addition, since all the components 2 and 3 mounted on the printed circuit board 1 are covered with the “cover and heat sink” 5, the components 2 and 3 mounted on the printed circuit board 1 are protected from a mechanical shock.
