Patent JP-2000167389-A (JP)
Title: Gas refining method
Inventor: THOMAS HISHAO-RINGU HISHANGU
IPC: C01B32/40
Filed: 1999-12-03
Abstract: PROBLEM TO BE SOLVED: To efficiently remove carbon monoxide, hydrogen, carbon dioxide and water from air when a high purity nitrogen gas is prepared by compressing a supply gas, then heating the supply gas by the compression heat to bring the gas into contact with a catalyst, and oxidizing carbon monoxide into carbon dioxide. SOLUTION: Air is compressed by a main air compressor and heated by the compression heat, and next, this heated air is supplied into a column 18 filled with a carbon monoxide-oxidizing catalyst, which oxidizes the carbon monoxide contained in the air into carbon dioxide, and at the same time, converts a part of hydrogen into water. After that, a gas flow containing a reduced amount of carbon monoxide is supplied to a heat swing adsorption or a pressure swing adsorption system. The columns 28, 30 of this system are filled with a three-layer material respectively. The first layer is an active alumina adsorbent layer 34 which adsorbs water, and the second layer is an oxidizing catalyst (Pd or Pt bearing alumina) layer 36 which converts the residual hydrogen to water.  The third layer is a zeolite 13x adsorbent layer 38 which adsorbs water generated by the oxidation of hydrogen and the residual carbon dioxide.

Title: Spherical sliding bearing
Inventor: OUCHIDA NOBUYUKI
IPC: F16C23/04
Filed: 1996-12-10
Abstract: PROBLEM TO BE SOLVED: To uniformalize a bearing surface pressure across the total bearing width so as to improve service life and reliability of a spherical sliding bearing by deviating the center of the radius of curvature of each spherical surface by a preset distance to the opposite side to the center of gravity of a rotor along the shaft direction from the center of the bearing width. SOLUTION: The center Y of the radius of curvature R of spherical surfaces 2a, 2b is shifted by a preset distance L to the opposite side of the center of the gravity of a rotor along the axial direction from the center X-X of the bearing width W. Provided that the bearing width is W, the radius of curvature of spherical surfaces 2a, 3a, is R, a frictional coefficient is α, an axially unbalanced quantity of bearing surface pressure load is Q, and (a) is a constant, a rotational moment M generated by Q is a.L.W and a rotation blocking moment M' owing to the maximum frictional reaction generated by friction between frictional surfaces 2a, 3a is a.W.α.R and if L for making M and M' equal to each other is sought, it may be expressed as L=α.R.  Meanwhile, when a rotary shaft 1 is supported by a bearing inside race 2, since the bearing inside race 2 turns until the rotational moment M makes balance with a rotational blocking movement M', the bearing surface pressure p is uniformalized across the total size of the bearing width W.

Title: Semiconductor device
Inventor: DAVID P BAUER
IPC: H01L29/201
Filed: 1997-12-16
Abstract: PROBLEM TO BE SOLVED: To provide a high-performance semiconductor device having excellent structural, optical, and electronic characteristics. SOLUTION: A 'C'-plane sapphire (Al2 O3 ) substrate is nitrized before an epitaxial process and, during the nitrization, the substrate is momentarily exposed to an ammonia gas at a temperature higher than 1,000 deg.C. The exposing time is not important in many states and can be adjusted within a range from several seconds to several minutes. In general, the substrate is exposed to the ammonia gas for about 5 to 10 minutes. The notarizing process changes the ammonium oxide on the surface of the substrate to ammonium nitride by replacing oxygen atoms on the surface with nitrogen atoms. It is possible to use another nitrogen precursor, such as the hydrazine, phenylhydrazine, or another organic nitrogen molecule, etc., which is sufficiently heat-treated at a temperature higher than 500 deg.C instead of the ammonia gas.

Title: Integrated spm sensor
Inventor: KAMIYA NOBUTAKA
IPC: G01B21/30
Filed: 1995-12-14
Abstract: PROBLEM TO BE SOLVED: To obtain an integrated SPM sensor by which the resolution of a measurement is increased by arranging only a probe part at a first cantilever in a liquid and also arranging the arrangement part of a photodetection mechanism at a second cantilever in the liquid. SOLUTION: The tip part of a probe part 3 at a first cantilever 4 and only a P-N photodiode part at the tip of a second cantilever part 6 are arranged in a liquid 21. In this arrangement state, a measurement in an ac mode in which a cantilever is vibrated in order to observe the inside of the liquid is performed. Then, since the first cantilever part 4 itself is not brought into contact with the liquid 21, it does not receive the resistance of the liquid 21 so as to be vibrated easily.  In addition, since the P-N photodiode part at the second cantilever part 6 to be used as a photodetection part is situated in the liquid, scattered light 23 in which evanescent light generated near the surface of a sample 22 to be measured is scattered by the probe part 3 is not scattered at the interface between the air and the liquid, and its can be detected with good efficiency by the photodetection part.
