  • Publication number: 20140087646
    Abstract: A vehicle air conditioning apparatus includes a case having a defrosting air outlet, a face air outlet and a foot air outlet, a mixing zone provided on a downstream side of a cold air flow path and a warm air flow path within the case and in which cold air and warm air are merged, and a face air outlet door which opens and closes the face air outlet. The face air outlet has a constantly open portion not closed by the face air outlet door. In the mixing zone, there is provided an air guide which has a warm air leading path guiding part of the warm air toward the defrosting air outlet preferentially. The air guide includes a guide wall forming the warm air leading path and having a warm air outlet which causes part of the warm air to flow toward the constantly open portion.

  • Patent number: 7909751
    Abstract: A centrifugal separator includes a sample line and a rotating apparatus portion including a rotor that has a rotor chamber. The centrifugal separator centrifugally separates a sample by supplying the sample from the sample line into the rotor and driving to rotate the rotor in the rotor chamber and discharges the centrifugally separated sample from the rotor via the sample line. The centrifugal separator includes a sterilizing apparatus for sterilizing at least a portion with which the sample is brought into contact by making a sterilizing fluid flow through the sample line.

  • Publication number: 20040234560
    Abstract: The present invention relates to a naturally derived cosmetic material obtained from bean broth, or by being fermented it or treating it with enzymes, and to a manufacturing method thereof. The method for manufacturing the cosmetic material of the present invention is characterized in that beans are added to a water-based solvent and heated, and the bean broth thus obtained is subjected to fractional purification, to inoculation with Bacillus natto and fermentation culturing, or to the action of soybean Aspergillus bacteria-derived proteases. Because the cosmetic material obtained by this method has excellent SOD activity, cytotonic activity, collagen-formation accelerating ability, antibacterial activity, and tyrosinase inhibiting action, this cosmetic material inhibits the peroxidation of skin lipids and prevents skin aging, and can be appropriately used as a beauty product having excellent functionality in the skin.

  • Patent number: 6005592
    Abstract: An image processing apparatus suitable for three-dimensional high speed image processing can be realized by improving the memory address control and the access method, that is, by improving the data transfer speed between the image memory and the other unit. The image processing apparatus comprises the pixel forming unit (1) for forming frame data for each pixel; an image memory (2) constructed by a plurality of banks (3, 4) to which row addresses are inputted through a row address input system (6) and column addresses are inputted through a column address input system (7); and the DRAM controller (5) for controlling the image memory (2).
