Title: Low-resistance film forming coating liquid, low-resistance film, its manufacture, low-reflection low-resistance film, and its manufacture
Inventor: ABE KEISUKE
IPC: B82Y99/00
Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To provide a low-reflection low-resistance film by forming a film superior in conductivity and weather resistance by a low-temperature processing, when a film is formed on a glass substrate such as a CRT face. SOLUTION: TiOx (1.0<=x<=2.0) fine particles are nitrogen atom-containing titanium oxide fine particles. When the average primary particle size of Ag fine particle exceeds 100nm, the scattering of visible light on the formed film is increased, and the transparency of the film decreases. When the average particle size is 10nm or below, the uniform dispersibility and dispersion stability of the Ag fine grains in a coating liquid is impaired. The nitrogen atom quantity of the nitrogen atom-containing titanium oxide fine particles is preferably set to the range of 0.3-30wt.% with respect to the sum of titanium atoms and oxygen atoms. When the nitrogen quantity is below 0.3wt.%, the suppression of the generation of the oxygen radical is difficult, and the weather resistance of the formed film is insufficient.  When the nitrogen quantity exceeds 30wt.%, the nitrogen atom-containing titanium oxide fine particles are easily oxidized, and the oxidation resistance of the film is insufficient.

Filed: 1996-11-12
Abstract: PROBLEM TO BE SOLVED: To reduce heat energy cost by a simple process and inexpensively obtain cullet by mixing trona ore with silica sand, calcining the mixture under prescribed conditions and heat melting the calcined material. SOLUTION: After trona ore prepared so as to have <=10mm particle diameter is mixed with silica sand or before the prepared trona ore is mixed with silica sand, calcination is carried out under oxygen-containing atmosphere at 500-900 deg.C for >=5min. Thereby, Na2 CO3 .NaHCO3 .2H2 O which is a main component of trona ore is decomposed and the produced CO2 and H2 O are scattered to form Na2 CO3 and an organic substances in impurities are removed by combustion. Thus calcined mixture of trona ore with silica sand is heated and melted. The mixture of trona ore with silica sand can be melted at relatively lower temperature for relative shorter heating time by mixing trona ore with silica sand in (45/55) to (30/70) weight ratio of Na2 O/SiO2 .  The heating and melting temperature is normally >=1,000 deg.C and the temperature is 1,000 deg.C to 1,300 deg.C for 30-90min from the viewpoint of durability of a furnace.

Filed: 1990-11-22
Abstract: PURPOSE: To lessen the skew arch fact of the data acquired in spiral form by interpolating or extrapolating the obtained projection set in which the spiral offset from two sensor vs. crest semi-scans acquired near the slice plane is lessened. CONSTITUTION: The slice plane 14 for an imaging object 12 parallel with the image plane is confirmed. Then the data about the beam source 10 vs. crest projection set is acquired over a rotation of the beam source 10 for 2π. The object 12 is moved along the Z-axis and the beam source 10 is rotated so that the imaging plane intercepts the slice plane 14 during acquisition of the beam source 10 vs. crest projection set. The obtained set is re-inserted to the sensor 18 vs. crest projection set. This sensor vs. crest projection set is divided into two semi-scans, and the data is jointed between the semi-scans so that the perfect sensor vs. crest projection set for 2π is prepared. Further the semi-scan data is extrapolated or interpolated to generate the sensor vs. crest projection set for the slice plane, and the obtained set is restructued to produce the intended slice image.
