  • Patent number: 7929135
    Abstract: The size of particles is detected accurately and at low cost even when there are few microparticles as impurities included in a liquid. Provided is a method of detecting a size of particles in a liquid by detecting diffraction fringes appearing due to the particles in the liquid by a light detection portion. Diffraction fringes are detected by a first light detection portion and a second light detection portion that are separated along the flow direction of the liquid. A peak time difference (T2) that is a difference between times at which peak values appear in a detection signal from the first and second light detection portion is measured, and an area (SQ) based on the waveform of the detection signal is measured. The sizes of the particles included in the liquid are detected based on the peak time differences (T2) and the areas (SQ) that were measured.

  • Publication number: 20090313783
    Abstract: A vacuum cleaner is disclosed, and this cleaner maintains sucking power at a high level while it resists lowering the suction force although it sucks dust. The vacuum cleaner includes a cylindrical dust collecting case which takes air in sucked by an electric air blower and including dust. The case includes a suction port through which the air including dust flows into the case along a tangent line, and a dust collector communicates with the port. A dust filter in the case is placed in an air-duct through which the case communicates with the electric air blower. This structure allows whirling airflow in the case to whirl continuously in the case, so that dust can be removed from the filter even if the dust attaches to the filter. As a result, sucking airflow can be always secured.

  • Patent number: 7581584
    Abstract: An air conditioning seat device includes an air blower, and a dehumidifier for dehumidifying the air sent from the air blower owing to adsorption, and blows out the dehumidified air to holes provided on a skin of a seat through an air duct. In this makeup, the sweat on the body surface and in the clothes is rapidly vaporized, causing a large amount of vaporization heat loss. Accordingly, the human body feels coolness, and steaminess on the skin is suppressed owing to the sweat vaporization.

  • Publication number: 20070134742
    Abstract: The present invention provides diagnostic reagent or reagent kit whereby the presence of adenocarcinoma cells can be detected in cells obtained from uterine cervix obtained for cytodiagnosis, in particular, the presence of adenocarcinoma can be specifically detected in distinction from squamous carcinoma cells; and methods of detecting adenocarcinoma cells. Adenocarcinoma cells are detected by determining cytokeratin 8 with use of cytokeratin 8 antibody optionally with its secondary antibody. Cytokeratin 8 is contained in the largest amount in adenocarcinoma cells among cells obtained from uterine cervix. The detection sensitivity is increased by employing HIK 1083 antibody together. The subject specimen may comprise either uterine cervix tissues or individually dispersed cells.

  • Publication number: 20070122909
    Abstract: The invention provides methods of treating cells wherein cells in a specimen containing mucus-producing cells are stabilized, mucus in the specimen is removed without affecting the cell morphology, or cells in the specimen are dispersed individually; and reagent kits to be used in said treating methods. After the cells are stabilized by treatment with a solution containing an aldehyde compound, the cell populations can be dispersed by treatment with protease. In the case of specimens containing cells aggregated with mucus, the processes of stabilizing and treating with protease may be conducted after the mucus is removed. In order to remove mucus, cysteine and/or a compound derived therefrom is preferably used.
