  • Publication number: 20240123950
    Abstract: A vehicle moving apparatus may include a housing extending in a first direction; an elevator coupled to the housing to be movable in the first direction and another direction opposite thereto, extending in a third direction and being inserted to be drawable into an underside space of a vehicle, and configured to lift or lower a wheel of the vehicle; and a wheel assembly coupled to the elevator and configured to move the housing and the elevator in a direction toward the vehicle or in a direction opposite the vehicle, wherein the wheel assembly includes a wheel rotatably provided with a vertical direction as an axis, and configured to movably support the elevator; and an actuator coupled to the wheel and configured to provide power for rotating the wheel, wherein the wheel is rotatable such that a diameter of the wheel is aligned between the first and third directions.

  • Patent number: 11493847
    Abstract: The present invention relates to a structure for a quantum dot barrier rib and a process for preparing the same. The structure for a quantum dot barrier rib of the present invention comprises a cured film having a uniform film thickness and an appropriate range of film thickness. Here, the reflectance RSCI measured by the SCI (specular component included) method and the reflectance RSCE measured by the SCE (specular component excluded) method are reduced, and the ratio between them (RSCE/RSCI) is appropriately adjusted, so that it is possible to satisfy such characteristics as high light-shielding property and low reflectance at the same time while the resolution and pattern characteristics are maintained to be excellent. In addition, when the structure for a quantum dot barrier rib is prepared, it is possible to form a multilayer pattern having a uniform film thickness suitable for the quantum dot barrier ribs in a single development process. Thus, it can be advantageously used for a quantum dot display.

  • Publication number: 20220206389
    Abstract: The structure for an optical device according to an embodiment comprises a protective layer formed from a photocurable siloxane resin composition, wherein the protective layer is capable of serving not only to protect or seal a light emitting element such as a mini-LED chip from external heat or moisture, but also to improve such optical characteristics as brightness and contrast ratio of light emitted from the light emitting element through the light diffusion effect.

  • Patent number: 7261906
    Abstract: A process for preparing As4O6 comprises successively heating and cooling a mixture of natural Sinsuk and 40% alcohol in a ratio of about 1: about 1 for about 1 to about 2 hour(s) resulting in a product, successively washing the product with distilled water thereby forming washed precipitates, maintaining the washed precipitates at about ?40° C. for 24 hours, defrosting, filtering, and drying the precipitates, and successively heating and cooling the precipitates to obtain the final As4O6 product.

  • Patent number: 6589567
    Abstract: This invention is about the identification of the HD-2, a natural chemical substance that was separated and purified from a natural product, Sinsuk, as arsenic hexoxide (As4O6) and about its therapeutic efficacy as an anti-cancer drug and pharmaceutical composition. Arsenic hexoxide (As4O6), a natural chemical substance obtained from Sinsuk after eliminating the toxic property, has a potent anti-cancer efficacy by its direct cytotoxicity on tumor cells and suppresses the formation of new blood vessels of tumor masses, which results in complete cure of malignant cancers.
