Abstract:
Provided is a portable electronic device having a removable hard disk drive in which the hard disk drive is adapted to have a slot-type removable shape, thereby allowing the hard disk drive to be conveniently mounted and used, and when the hard disk drive is detached, power is cut off before detaching the hard disk drive, and when the hard disk drive is mounted, power is automatically supplied after the hard disk drive is completely mounted, thereby preventing damage by a voltage shock. The device includes: a case having a mounting opening on one side thereof, the mounting opening connected to a mounting space inside the case, thereby providing a passage to the mounting space, and the mounting space having a connector disposed on the bottom of the inside of the mounting space; a hard disk drive slidingly inserted into the mounting space through the mounting opening of the case, and having terminals which become in contact with the connector when the hard disk drive is completely mounted; and a power switching unit sensing an operation for attaching or detaching the hard disk drive, thereby cutting off power before detaching the hard disk drive and providing power after mounting the hard disk drive.
Abstract:
Disclosed are a light emitting apparatus, a method of manufacturing the same, and a lighting system. The light emitting apparatus includes a body, a light emitting device on the body, a conductive member electrically connected with the light emitting device on the body, a resin member surrounding the light emitting device, and an inorganic oxide layer having a refractive index less than a refractive index of the resin member on the resin member.
Abstract:
Disclosed is a method for manufacturing a fluorescent material. The method includes: putting the fluorescent material into a first solution, and agitating the fluorescent material and the first solution; putting a nano fluorescent material having a nano size into the first solution, and agitating the nano fluorescent material having a nano size and the first solution; and separating supernatant from the first solution including the fluorescent material, and drying the fluorescent material. Disclosed is a light emitting device. The light emitting device includes: a body; a light emitting element mounted on a cavity formed in the body; a resin formed in the cavity; and a fluorescent material added to the resin, wherein a nano fluorescent material having a nano size is adsorbed in the fluorescent material.
Abstract:
The present invention relates to a composition comprising extracts of Gramineae plant that improves cell viability under hypoxic conditions by inhibiting apoptosis. Thus, the extract of Triticum aestivum L., one of the Gramineae plant, of the present invention, in particular, prevents damage of brain, heart and kidney in animal models of ischemic diseases, and it also improves memory in an animal model of Alzheimer's disease. Therefore, a composition comprising extracts of Gramineae can be used as therapeutic agents or health care foods for preventing and treating ischemic diseases and degenerative brain diseases.
