Abstract: The objective of the present invention is to provide an ammonia decomposition catalyst that is capable of efficiently decomposing ammonia into nitrogen and hydrogen and that has high mechanical strength, and a method for producing hydrogen and nitrogen by using the ammonia decomposition catalyst. The ammonia decomposition catalyst according to the present invention is characterized in comprising cobalt (A); one or more rare earth elements (B) selected from cerium, yttrium and lanthanum; one or more alkaline-earth metal elements (C) selected from barium and strontium; zirconium (D); and one or more calcium compounds (E) selected from calcium carbonate, calcium oxide and calcium hydroxide; wherein the ammonia decomposition catalyst comprises the cobalt (A), the rare earth element (B), the alkaline-earth metal element (C) and the zirconium (D) as metals or oxides.

Abstract: In the present invention, a bis (fluorosulfonyl) imide metal salt is an alkali metal salt of bis (fluorosulfonyl) imide or an alkaline earth metal salt of bis (fluorosulfonyl) imide. The bis (fluorosulfonyl) imide metal salt has an average particle diameter of not less than 0.1 mm, or has an average moisture absorption rate of not more than 2.5 mass ppm/cm2·min when sealed in a PE bag having a thickness of 80 ?m and left for 30 minutes at 23° C. and 65% humidity.

Abstract: In a colorimetric absorbance measurement apparatus, a filter assembly on which a plurality of filters are arranged in a circular pattern is continuously rotated by a motor at a regular speed based on a motor drive signal fed from a motor drive circuit, each of the filters being characterized by passing only such light components that have wavelengths falling within a range centering on a specific wavelength. The motor drive signal produced by the motor drive circuit is also fed into a timing generator circuit. The timing generator circuit supplies an A/D conversion start signal to an A/D converter in synchronism with the timing at which a selected one of the multiple filters is positioned on the optical axis of a measuring light beam.

Abstract: An operation guidance method of clinical system which enables a doctor or nurse unskilled in testing to operate the clinical system without operation error by providing operation guidance. In the system, an initial screen shows numerals 1 to 5 indicating the order of procedure of sample test and character information indicating the contents of works (1 confirmation of sample, 2 confirmation of request, 3 feeding samples, 4 confirmation of result and 5 finish) as contents displayed in an operation menu. When an operator selects a “start” button, display images showing as guidance on the respective works are sequentially displayed. Further, a display image as guidance on arbitrary one of the works may be displayed by selection of one of the works in the operation menu.

Abstract: A spindle motor comprises a rotary sleeve; a rotor hub which is integrally rotated with the rotary sleeve; a stationary sleeve; and a stationary support extending upwardly from the stationary part, the rotary sleeve being fitted onto the outer peripheral surface of the stationary support, and radial and thrust hydrodynamic bearings being provided on the relative sliding surfaces of both rotary sleeve and stationary support. A pair of annular grooves which partially overlap each other in the axial direction are peripherally provided on the rotary sleeve and stationary support, thereby providing a labyrinth chamber to suppress the outflow of the lubricant.
