  • Patent number: 7220483
    Abstract: Fluoropolymer particles are subjected to high energy treatment so as to change the chemical functionality of the particle surfaces and thereby change the surface characteristics of the particles. These characteristics improve the usefulness of these particles and can make them highly dispersible, even in water. The surface treated fluoropolymer particles are subject to a chemical crosslinking process, or alternatively, are subject to a high energy treatment process, and may optionally be pretreated with a macromolecular chemical species prior to the foregoing processes. The high energy treatment can be used to both surface treat the fluoropolymer particles and in some embodiments, may also cause chain scission of the fluoropolymers to thereby reduce the molecular weight of the fluoropolymer particles. The surface treated fluoropolymer particles can be used to form fluoropolymer coatings on various substrates.

  • Patent number: 7220785
    Abstract: This invention provides a mounting method for reliably connecting mounting components electrically. Specifically, an anisotropically conductive adhesive can be composed of crushable microcapsules and a second liquid in which the microcapsules are dispersed. Each microcapsule encloses a first liquid and a conductive particle. The first liquid can react with the second liquid at normal temperatures to cure the second liquid. This anisotropically conductive adhesive can be applied on a flexible printed circuit (FPC). Then, a drive IC is mounted and pressed on the FPC to crush the microcapsules between electrode pads provided on the drive IC and electrode pads provided on the FPC, thereby bonding the electrode pads. Subsequently, the anisotropically conductive adhesive is heated to plasticize a capsule wall of each microcapsule, thereby bonding the drive IC and the FPC.

  • Patent number: 7160614
    Abstract: Crystalline superfine particles capable of emitting light depending upon a time-rate-of-change of a stress and controlled in grain size in the range from 5 nm to 100 nm are complexed with another material such as resin. The crystalline superfine particles are manufactured by using aggregates of molecules, i.e. inverted micelles, which orient hydrophilic groups of surfactant molecules inward and hydrophobic groups outward in a nonpolar solvent and which contain metal ions of a metal for forming the crystalline superfine particles dissolved in water inside the inverted micelles. Alternatively, they are manufactured by using inverted micelles enveloping precursor superfine particles, in which precursor superfine particles are enveloped in water inside the inverted micelles. The crystalline superfine particles are excellent in dispersibility in another material to be complexed, enhanced in emission efficiency and usable to make a transparent stress emission material.
