A complex type cleaner includes: a cleaner body having at least one of a dust collecting container for storing dust or foreign materials and a water collecting container for storing contaminated water; and a suction head having a dust suction opening disposed at a lower portion of the cleaner body and sucking dust when the cleaner performs a vacuum cleaning and a suction head having a suction nozzle for sucking contaminated water when the cleaner performs a water cleaning. By implementing both vacuum cleaning function for sucking dust and water cleaning function in one cleaner, a cost can be reduced, users' convenience can be improved, and the cleaner can be conveniently kept in storage.

A suction apparatus of a cleaner includes: a suction motor inserted in a cleaner body and generating a suction force; a filter for collecting dust or filth sucked by a suction force generated for the suction motor; a suction head connected to the filter by a suction pipe and sucking dust and filth on the floor by the suction force generated from the suction motor; and an auxiliary suction unit installed at the opposite side of a side where the suction pipe of the suction head is connected. A cleaning performance is enhanced by compensating a suction force at a portion where the suction force is relatively weak.

Disclosed is a mounting structure of a blower for a vacuum cleaner comprising a mounting cover for fixing the blower to a body base so that the blower is structurally separated from a body cover. The mounting cover is put on the upper surface of the blower disposed on supporting ribs, and connected to the body base, and then the body cover is put on the body base. The blower is fixedly interposed between the supporting ribs and the mounting cover and separated from the body cover, thereby preventing oscillation generated by the blower from being transmitting to the body cover and then preventing the oscillation of the body cover and the consequently occurring noise of the body cover.

The present invention relates to a method for preparing mulberry leaf powder and ice cream containing thereof. More particularly, the present invention could provide a method for preparing mulberry leaf powder by blanching mulberry leaf in an aqueous solution containing 0.05˜0.5% of sodium bicarbonate, and drying and pulverizing said mulberry leaf. And ice cream of the present invention is prepared by mixing said mulberry leaf powder in an amount of 0.5˜5% by weight of the total ice cream with the mix base for ice cream. The ice cream products containing mulberry leaf powder of the present invention are functional as well as palatable.
摘要:
Disclosed is a ubiquitous city (u-city) exclusive middleware to provide services to a u-city. A middleware device performs a role corresponding to a brain of a human being by aggregating u-city information collected through wired and wireless converged and complex communication networks, analyzes the aggregated information, finds an optimal service based on reasoned current context information and a given command, and processes the found service to be executed. The u-city exclusive middleware performs various embedded functions by operating in a three-tier method through a u-city infrastructure and a u-city portal, and an operating method and executed functions of the middleware follows a method of an operating system of a typical computer system.

Disclosed is a liquid crystal display device including a first substrate, a second substrate, and a liquid crystal layer interposed there between. The first substrate is provided with gate lines and data lines thereon. The gate lines and data lines cross with each other and are insulated from each other. Pixel electrodes are stacked on the gate lines and data lines. Each pixel electrode includes first and second sub-pixel electrodes spaced apart from each other and a connection electrode, which connects the first sub-pixel electrode to the second sub-pixel electrode. The second substrate is provided with a common electrode thereon. The common electrode includes a first domain divider formed on the center of the first sub-pixel electrode and a second domain divider formed on the center of the second sub-pixel electrode.

A thin film transistor substrate, wherein the moving area of electrons between source and drain electrodes of a thin film transistor (TFT) is minimized, the moving distance of electrons is increased, and the sizes of capacitors defined by a gate electrode together with the respective source and drain electrodes are identical to each other so that an off current generated when the TFT is off can be minimized; a method of manufacturing the thin film transistor substrate; and a mask for manufacturing the thin film transistor substrate. Accordingly, it is possible to minimize an off current induced due to a phenomenon of electron trapping by light.
