摘要:
A method and apparatus for recording/reproducing data is disclosed. The apparatus for recording/reproducing data comprises a diffraction element splitting light diffracted or reflected from a recording medium into a main beam and first and second sub beams, the main beam and the first and second sub beams having no interference from one another; a light-receiving part detecting the main beam and the first and second sub beams; and a controller controlling a position of the diffraction element based on at least one light capacity of the detected beams or the detected position.

The present invention provides a disc cartridge assembly, by which loading/unloading of a disc is facilitated to enable both one use in a cartridge state and the other a use as a single disc entity. The present invention includes a lower case having a window for a drive access, an upper case provided onto the lower case, the upper case having an exposure window provided to a central part to expose a label face of a disc, a rotating ring rotatably provided within the upper and lower cases to receive an outer circumference of the disc, at least one shutter provided within the upper and lower cases to open/close the window by interoperating with a rotation of the rotating ring, and a rotating means for rotating the rotating ring by interoperating with an external device.
摘要:
The present invention relates to a skin-whitening composition comprising a paper mulberry extract, and more particularly to a skin-whitening composition containing an extract of Acer barbinerve Max., Acer barbinervis var. glabrescens, Wikstroemia trichotoma, Acer tschonoskii var. rubripes, Edgeworthia chrysantha, Broussonetia papyrifera for. Oppositifolia, Broussonetia papyrifera for. Lucida, Daphne kamtschtica or Broussonetia kazinoki Siebold, which can be used safely on the skin without causing side effects and has excellent effects of inhibiting melanin production and pigmentation.
摘要:
The present invention relates to a skin external composition comprising an extract of the flower and fruit of paper mulberry, and more particularly to a skin external composition containing, as an active ingredient, an extract of flower and fruit of paper mulberry, which shows an excellent skin-whitening effect by effectively inhibiting melanin production.
摘要:
The present invention relates to hydrogel particles coated with lipid, which are made from dispersing hydrogel particles in an organic solvent in which lipids are dissolved, and to a method for manufacturing same. Unlike the existing method for manufacturing hydrogel core vesicles, the present invention can effectively manufacture same by using an emulsification method, without involving the steps of chemical treatment of the surface of hydrogels or dilution, thereby facilitating mass production and preventing the decrease of drug encapsulation efficiency. The present method could be widely used for research on delivery carriers of oil/water-soluble active material or cell structure reproduction and more particularly, a keratinocyte mimetic of the present invention containing natural moisturizing factors can contain a large quantity of bound water for a long time, thereby exhibiting superior capability to retain moisture and moisturize, and providing a composition for an ingredient in cosmetics for moisturizing.
