  • Patent number: 8398861
    Abstract: A separation method for extracting a target 1 from a separation subject (101) in which the target (1) to be extracted and a non-target (2) are mixed. The method includes the steps of distinguishing the target (1) from the non-target (2); obtaining positional information of the target (1) distinguished; attaching a liquid to the target (1) based on the positional information; and extracting the target (1) from the separation subject (101) by bringing a catch member (140) into contact with the separation subject (101) such that viscosity of the liquid causes the target (1) to adhere to the catch member.

  • Patent number: 7863409
    Abstract: A separation object including at least two types of resins with different glass transition temperatures (glass transition temperature of a first resin 1<glass transition temperature of a second resin 2) is placed on a separating member 3. Next, primary heating is applied at a temperature between the glass transition temperatures of the first resin 1 and the second resin 2, and pressurization is additionally performed to cause the first resin 1 to adhere to the separating member 3. Subsequently, a heat history of secondary heating at a temperature higher than the primary heating temperature is applied to detach and recover the second resin 2 by restoring the shape of the second resin 2, while the first resin 1 adhering to and retained by the separating member 3 is detached by a blade 5 and the like for recovery.

  • Patent number: 6808845
    Abstract: The present invention relates to an electrode metal material for batteries, capacitors, etc, used in contact with non-aqueous electrolyte, and particularly to a capacitor formed of the electrode metal material, and provides a valve metal material capable of decreasing the internal resistance of the capacitor. The electrode metal material comprises a valve metal material and numerous carbon particles included in the surface of the valve metal material. The carbon particles are further fixed in the surface of the valve metal material so as to expose to the surface. The electrode metal material is coated with an activated carbon layer and used as a double-layer electrode for an electric double-layer capacitor. The carbon particles included in the surface ensure conduction between the activated carbon layer and the valve metal material.

  • Patent number: 6326694
    Abstract: A printed circuit board includes an uncured substrate material with closed voids which are disposed with a through-hole. When the through-hole is formed, voids which exist in the substrate material open from inner wall of the through-hole to form a hollow-shaped part. By filling the through-hole and the hollow-shaped part with conductive paste, the adhesion improves by the increased holding effect between the conductive paste and the wall surface of the through-hole.
