  • Patent number: 9863969
    Abstract: A method of evaporation control of a sample which is stored in a thermally insulated state is configured for preventing evaporation or denaturing of the samples and specimens. The method includes carrying the samples contained in individual containers out from a cold container having a capability of cold storage. An elapsed time that each sample container has been removed from the cold container is measured and is compared with a preset time. If the elapsed time is less than the preset time, the sample container can be returned to the cold container. An alarm is output if the elapsed time exceeds the preset time.

  • Patent number: 7823469
    Abstract: A sample dispensing apparatus dispenses a sample from a container accommodating a sample such as blood or urea sampled for checking. This sample dispensing apparatus can prevent internal contamination of the apparatus due to dripping of the sample and abnormal sucking operations caused by drainage, condensation and fixing of the sample. The sample dispensing apparatus according to the present invention comprises a dispensing device for dispensing a sucked sample, a dispensing head provided in the dispensing device, and a disposable nozzle chip dismountably set on the dispensing head. In this apparatus, dispensing of a sample to child sample containers is performed exchanging the child sample containers with new ones. When the state, in which dispensing to the child container cannot be carried out, is continued for a prespecified period of time, the nozzle chip is automatically released from the dispensing head.

  • Publication number: 20090166583
    Abstract: An anisotropic dye film that exhibits a high dichroism and a high uniformity in a coating film is formed at a high level of productivity. In the composition for an anisotropic dye film containing a dye and being capable of forming a lyotropic liquid crystal phase, the time until the relaxation modulus G measured 0.01 seconds after the application of strain drops to 1/10 is equal to or shorter than 0.1 seconds at a temperature of 5° C. The composition contains a cation and a strongly acidic anion that respectively account for contents in the range of 0.9 to 0.99 equivalence and in the range of 0.02 to 0.1 equivalence relative to the content of the acidic groups of the dye. An anisotropic dye film is formed using this composition for an anisotropic dye film. A polarizing element is formed using this anisotropic dye film.
