Provided are a nitride semiconductor device and method of manufacturing the same. In the method, semiconductor nanorods are vertically grown on a substrate, and then a nitride semiconductor thin film is deposited on the substrate having the semiconductor nanorods. Accordingly, a high-quality nitride semiconductor thin film can be deposited on a variety of inexpensive, large-sized substrates. Also, because the nitride semiconductor thin film containing the semiconductor nanorods can easily emit light through openings between the nanorods, internal scattering can be greatly reduced. Thus, the nitride semiconductor thin film can be usefully employed in optical devices such as light emitting diodes and electronic devices.

A home-style decoctor endowed with steamy boiling function includes a main body equipped with a heater; a heating vessel; a support plate for allowing a to-be-boiled object to be placed above the surface of water stored in the heating vessel; means for supplying water for boiling into the heating vessel so that the to-be-object is immersed; a steam collector for gathering steam produced when the to-be-boiled object is decocted with water; means for condensing the steam collected into the steam collector; and steam/condensed water guiding means for leading the steam present in the heating vessel to the steam collector and the condensed water placed in the steam collector to the heating vessel. With such construction, undried or white ginseng can become red ginseng extract by producing such useful components as several kinds of phenolic compounds and maltol, anti-oxidants, and ginsenosides Rg and Rh through steam-boiling, drying and re-boiling.

The present invention relates to a cosmetic composition which mimics the extracellular matrix to stimulate the regeneration of skin cells, and more particularly to a cosmetic composition which contains active ingredients consisting of low-molecular-weight materials, which easily permeate through the skin, at a composition ratio similar to that in the extracellular matrix. The cosmetic composition stimulates the repair of the skin to maintain homeostasis and is effective for the regeneration of skin cells.

The present invention relates to a method for sharing data of a device in M2M communication and a system therefor. The invention comprises: a step of allowing a resource user terminal to request access authority of protected resource data to a resource owner terminal, in order to prevent a security threat; a verification step of allowing the resource owner terminal to verify the resource user terminal to request the setting of the access authority to an M2M server, and to transmit a verification key issued from the M2M server to the resource user terminal; an access authority setting step of allowing the M2M server to generate an access authentication key based on the verification key, and to transmit the access authentication key to the resource user terminal; and a using step of allowing the resource user terminal to inquire about the protected resource data from the M2M server based on the access authentication key, and to use the protected resource data.

Transmitting devices facilitate privacy protection of content broadcasted from the transmitting device to a receiving device without the need to modify the receiving device. A transmitting device may be adapted to acquire content, such as audio and/or video data, to be broadcasted by the transmitter for reception and use by a receiving device. A transmission range is selected to define a distance for broadcasting the content from the transmission device for reception and use by a receiving device. A frequency is also selected to be used for broadcasting the content. With the transmission range and frequency selected, the transmitting device may broadcast the content according to the selected transmission range and frequency.

There is provided a horizontal linear vibrator including a bracket providing an internal space; a vibration unit mounted in the internal space and including a mass body moving horizontally and linearly; and a magnetic field unit including a magnet fixed to the mass body and a coil installed within a magnetic field of the magnet and generating electromagnetic force to allow the vibration unit to move horizontally and linearly, wherein the coil includes a coil line disposed between the bracket and a printed circuit board and extending outside of the internal space of the bracket such that the coil line is connected with the printed circuit board for applying power from an external source to the coil outside of the internal space of the bracket.
摘要:
The present invention provides a horizontal linear vibrator which can increase vibration strength while at the same time guaranteeing a sufficiently long lifetime and satisfactory responsivity. The horizontal linear vibrator includes a casing, a bracket, a vibration unit and springs. The bracket and the casing form the internal space therein. A coil is provided above the bracket such that the center axis thereof is oriented in a horizontal direction. The vibration unit is disposed through the coil and comprises a magnetic field generating unit and a weight. The magnetic field generating unit includes a magnet assembly and a yoke. The magnet assembly has magnets which are provided on opposite sides of a magnetic body core such that the similar magnetic poles of the magnets face each other. The weight is mounted to the magnetic field generating unit. The springs are coupled to the casing or the bracket and elastically support the vibration unit.
