In an optical device, a number of structures having higher portions or lower portions are arranged at a fine pitch equal to or shorter than a wavelength of visible light on a surface of a base. Each of the structures is arranged to form a plurality of arc track rows on the surface of the base, and to form a quasi-hexagonal lattice pattern, and the structure has an elliptical cone or truncated elliptical cone shape having a major axis in a circumferential direction of the arc tracks.

An optical information recording medium, which includes both of a land surface and a groove surface as a recording track and presents high signal quality. The optical information recording medium includes both a land and a groove as the recording track on a substrate, in which a laser light is irradiated from a reverse side of the substrate to thereby carry out a recording and a reproduction, and an inclination angle of a groove side is 25° or more and 40° or less, and both of arithmetic average roughness (Ra) on the land surface and the groove surface are assumed to be 0.2 to 0.7 nm.

The present invention provides such a measuring method of the CK isoform and a reagent therefor. Accordingly, the present invention provides a reagent for measuring creatine kinase (CK) activity comprising an antibody, wherein said antibody inhibits CK-M.sub.T subunit, but does not inhibit CK-M.sub.S subunit. The present invention also provides a method for measuring CK activity comprising determining an inhibition of CK of body fluids using a reagent for measuring CK activity, wherein said reagent comprises an antibody which inhibits CK-M.sub.T subunit, but does not inhibit CK-M.sub.S subunit.
摘要:
An audio signal recording and reproduction apparatus enabling a low frequency band signal component to be reproduced by existing reproduction apparatuses and a high frequency band component to be processed as well. A digital audio signal is divided into a low frequency band signal component and high frequency band signal component by a frequency band division filter. The low band signal component is subjected to straight PCM processing to maintain compatibility with existing reproduction methods. The high frequency band signal component is subjected to high frequency coding through a requantization circuit and entropy coding circuit. A comparison circuit compares the straight PCM signals and the high efficiency coded signals to determine if they will fit into a predetermined bit length and, when not fitting, causes the requantization circuit to perform requantization to shorten the bit length. The bit redistribution circuit performs redistribution between the straight PCM bit data and the high efficiency coded bit data. The wave data is recorded on a CD. On the CD may also be recorded the sub-code data of an entropy coding circuit and the number of requantization bits of a requantization circuit.

A method of constructing the top slab of a nuclear reactor container in which a flange for mounting the top head of the container is prepared separately from the sleeve of the container. When the outside diameter of the flange is greater than the inside diameter of a doughnut-shaped steel; reinforcement structure assembled on the container, the steel reinforcement structure is situated in place and then the flange is welded to the sleeve, thus shortening the construction period. Disclosed also is a nuclear reactor container constructed by this method.

The air flow rate detecting resistance element 1A or the temperature sensing resistance element 1B comprises a dielectric substrate 5A or 5B, a thin film type conductor 6A or 6B as a resistance element forming conductor, and a thin film type conductor 7A or 7B as a shield electrode element forming conductor. The resistance element conductor 6A or 6B and the shield electrode element conductor 7or 7B are formed by evaporation on the dielectric substrate 5A or 5B. The shield electrode element conductor 7A or 7B is provided in the vicinity of the resistance element conductor 6A or 6B an electrostatic capacity is formed therebetween. The shield electrode element conductor 7A or 7B is maintained at the lowest potential such as ground or a common potential. The guidance of high frequency radio waves to the resistance element 1A or 1B can be effectively prevented, so that the radio interference resistance of the hot film type air flow meter can be improved.

A platinum wire (2) is wound in the form of coil. An outer surface of the coiled wire (2) is overcoated with a glass member (4). The coiled wire (2) is welded to supporting member (3). An exothermic resistor (1; 1A, 1B) comprised the coiled wire (12), the glass member (4) and the supporting member (3), and has no bobbin therein. Such an exothermic resistor (1; 1A, 1B) free from a bobbin is used as a hot wire element (1A) and a cold wire element (1B) in a hot wire air flow meter. The quantity of heat generated on the coiled wire (2) hardly transmit through the supporting member (3) and is carried away almost through air. The transient response characteristics under sudden change of an amount of air flow can be improved.
