Abstract: PROBLEM TO BE SOLVED: To detect the abrasive condition of bearing components easily and accurately. SOLUTION: A coated layer 4 is formed on the face on the inner ring 3A side of a spacer 3E so as to be opposite to an end face 3d. This coated layer 4 is formed into a continuous ring shape in the circumferential direction along the outer circumferential face of a rotary shaft 1, and the outer diameter is a little larger than the extreme end side part of the end part 3c. The coated layer 4 is formed into a multilayer construction of an outside layer 4A and an inside layer 4B, both the outside layer 4A and the inside layer 4B are made of different metal from metal forming an inner ring 3A, an outer ring 3B, rollers 3C, and the spacer 3E as bearing components constituting a bearing 3, and they are formed out of softer metal than the metal forming the bearing components.  For example, when the bearing components are formed out of general bearing steel, the outside layer 4A is formed out of nickel, and the inside layer 4B is formed out of cobalt.

Title: Heat exchanger
Inventor: KAWAHARA KATSUYUKI
IPC: H05K7/20
Filed: 1989-02-14
Abstract: PURPOSE:To make it possible to close a device hermetically and to make it small in size and to prevent the occurrence of vibration, noise, etc., by a construction wherein the inside of a casing whose one side part is opened is partitioned from an opening by a partition wall to which a heating component is fitted and which is formed of a material of high heat conductivity, while the air inside the casing is made to flow by the drive of a plate-vibrating means provided with said partition wall interposed. CONSTITUTION:While a heating component 2 generates a heat when a power source is charged in the main body 11 of an electric apparatus, a prescribed pulse-form current flows through an electromagnet 6, and thereby a sinusoidal magnetic force is generated to make a vibrating plate 7 vibrate. If a current in a non-audio band of frequency of about 10Hz is let to flow on the occasion, noise or the like does not occur in the main body 11 of the electric apparatus. The vibrating plate 7 can vibrate flexibly since it has a certain degree of heat resistance and since it is connected in the opposite ends by an elastic material 8 having elasticity. By making the vibrating plate 7 vibrate in a heat exchanger 10 in this way, the air inside the heat exchanger 10 which is heated by the heating component 2 is exhausted outside from an opening 5c and also replaced by cool air around the heat exchanger 10.

Title: Production of quartz glass foam
Inventor: NAKAMURA RYOHEI
IPC: C03C11/00
Filed: 1989-02-14
Abstract: PURPOSE:To industrially and readily obtain a high-quality quartz glass foam at a low cost by reacting a cellular quartz glass preform containing a specific amount of OH groups with ammonia at a specified temperature, then heating and foaming the resultant reaction product. CONSTITUTION:A cellular quartz glass preform containing >=100ppm OH groups is reacted with ammonia at 800-1,300 deg.C and the resultant reaction product is then heated at 1,350-1,700 deg.C and foamed to provide the objective foam. The cellular quartz glass preform used as a starting agent can be produced by, e.g. vaporizing a silicon compound, such as silicon tetrachloride, highly purified by distilling operation, etc., feeding the vaporized silicon compound into an oxyhydrogen flame, carrying out flame hydrolysis to form fine glass powder and depositing the fine powder on a refractory rodlike target. Even if the cellular quartz glass preform is formed by binding quartz glass powder with a binder, the binder is thermally decomposed by heating at the high temperatures. Thereby, the resultant quartz glass foam is obtained as a high-purity foam without containing impurities.
