Title: Nickel super fine powder
Inventor: KATAYAMA EIJI
IPC: B22F1/05
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To improve particle size by controlling the average particle diameter and the existing ratio of a coarse particle having a particle diameter specific times as large as the average particle diameter respectively to a specific range. SOLUTION: The average particle diameter of a nickel super fine powder is controlled to 0.2-0.6 μm. Because the fine powder is a powder having a particle diameter distribution, the coarse particle having larger particle diameter than the average particle diameter is existed. When the existing ratio of the coarse particle is increased, the possibility that the coarse particle breaks through a laminated dielectric layer to be in contact with an adjacent inner electrode in electric circuit wise at the time of making an inner electrode film of a laminated ceramic capacitor thin is increased. As a result, the contact of the inner electrodes with each other makes short-circuit to damage the circuit.  Then, the existing ratio of the coarse particle having the particle diameter >=2.5 times as large as the average particle diameter in the nickel super fine powder is controlled to <=0.1% basing on the number as a reference. The fine powder is produced by properly selecting the concentration of nickel chloride vapor, the reaction temp. and a structure of a reactor in a vapor phase reaction.

Title: Laminate of functional material and production of the same
Inventor: IWAMOTO KAZUNARI
IPC: C03C27/06
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To restrain the vaporization of water in production process and to reduce the unevenness in composition, by setting the dispersion in moisture content in various parts of a functional material in a laminate produced by laminating the functional material between two transparent boards so as to have a value equal to or below a specific one. SOLUTION: This laminate is produced by placing a functional material in a liquid or wet gel form in a laminated state between substrate bodies 2 and 3 at least the one of which is partially or wholly transparent, by placing a sealing material 5 between margins of the substrate bodies 2 and 3 so as to surround and seal the material 4 and by setting the difference in moisture contents in various parts of the material 4 in a laminate 1 so as to become <=10%. When the material 4 consists of a cellulose derivative, water and an inorganic electrolyte, the material functions as a thermotropic material which reversibly changes its state between transparent state and cloudy one depending on the change of its temperature.  Since the concentration of the inorganic electrolyte alters the temperature where the state changes, the material 4 changes its state uniformly by reducing the difference in contents of moisture as solvent.
