摘要:
A measuring apparatus is provided with a light source (4), a first light-receiving element (5) and a second light-receiving element (6) which output signals corresponding to light intensity, a calculating part (12) and a memory part (13). The first light-receiving element (6) and the light source (4) are arranged so that transmitted light emitted from the light source and passed through a sample is received by the first light-receiving element (5). The second light-receiving element (6) is arranged so as to receive light other than the transmitted light emitted from the light source (4). In the memory part (13), a correlation between the output value of the first light-receiving element (5) and the output value of the second light-receiving element (6) when light is emitted from the light source (4) in a state where the sample is not present is stored. The calculating part calculates absorbance of a target component contained in the sample, from the output values of the first light-receiving element (5) and the second light-receiving element (6) when light is emitted from the light resource (4) in the state where the sample present, and from the correlation.

摘要:
The present invention relates to an analyzer (3) for analyzing a sample by taking an analytical instrument (20) out of a cartridge accommodating a plurality of analytical instruments and using the analytical instrument. The analyzer (3) includes a housing (4), an operational member (5) which is reciprocally movable relative to the housing, and a movable member (60) which moves, in accordance with the reciprocal movement of the operational member (5), reciprocally between a wait position and a take-out position for taking an analytical instrument (20) out of the cartridge. The movable member (60) is designed to engage an analytical instrument accommodated in the cartridge and take the analytical instrument (20) out of the cartridge.

There is provided a cold cathode fluorescent lamp that has excellent sputtering resistance and long life, even if high tube current is applied, and can be easily manufactured at low cost. In a cold cathode fluorescent lamp comprising a transparent tube having a fluorescent layer provided on an inner wall surface, containing a rare gas and mercury inside, and having both ends enclosed by sealing members, electrodes provided near both ends inside the transparent tube, and lead wires connected to the electrodes and provided through the sealing members, the electrode contains nickel as a main component and contains cerium metal or cerium oxide.
摘要:
A process for improving the coefficient of traction at high temperatures in a traction drive, and a tranction drive fluid for use therein. This traction drive fluid comprises the hydrogenated product of a dimer, a trimer or a tetramer of norbornanes and/or norbornenes, and exhibits excellent traction performance over a wide temperature range from low temperature to high temperature.

The present invention relates to a lubricating oil composition for traction drive, which consists essentially of:(A) a base oil containing as the main component a saturated hydrocarbon or hydrocarbons having fused ring and/or nonfused ring,(B) an ethylene-.alpha.-olefin copolymer having a number-average molecular weight of 800 to 8,000, and(C) an anti-wear agent.The lubricating oil compositions of the present invention are effectively used in winter and cold districts, since they have a high coefficient of traction and show a limited change in the coefficient of traction at low temperatures.
摘要:
A lubricant composition for transmission of power consisting essentially of (A) base oil of which main component is a saturated hydrocarbon having condensed ring and/or non-condensed ring, (B) one kind or more than two kinds of zinc dithiophosphate and/or oxymolybdenum organophosphorodithioate sulfide, (C) alkenyl succinimide and (D) rust inhibitor.

The present invention relates to a blood sugar level control system equipped with an insulin dispensing device 2 and a blood sugar measuring device 3. An attachment mechanism 4 is provided which serves to couple the insulin dispensing device 2 and said blood sugar measuring device 3 in a relatively movable manner. Preferably, the attachment mechanism 4 is constructed so that the blood sugar measuring device 3 is movable or slidable with respect to the insulin dispensing device 2. A blood sugar level control system can be provided which includes a blood sugar measuring device and an insulin dispensing device without using an adapter. Accordingly, it is possible to avoid a cost rise due to an increase in the number of parts as required. In addition, it is possible to prevent the blood sugar level control system from being unable to be used due to the loss of an adapter in the form of a different part.

The present invention provides a lubricating oil composition for a compression type refrigerator, containing a base oil having a kinematic viscosity of 2 to 1,000 mm2/s at 40° C. The base oil contains the following compounds (1) to (6) each having a molecular weight of 150 to 5,000 and a tertiary or quaternary carbon: (1) an alicyclic hydrocarbon, (2) a branched carboxylic acid ester of a polyhydric alcohol, (3) an alicyclic polycarboxylic acid ester, (4) polybutene, (5) an alkyl benzene and/or an alkyl naphthalene, and (6) a paraffinic mineral oil showing a 13C-NMR spectrum in which an area of peaks at chemical shifts in the range of 30 to 100 ppm accounts for 5 to 40% of the entire peak area and/or a naphthenic mineral oil having a naphthene content of 30 to 70% by mass. The composition has excellent traction performance, lubricating properties and stability.
