Abstract: Disclosed herein is a system for managing chemicals using Radio-Frequency Identification (RFID). A storage facility identification tag, attached to a chemical storage facility in a laboratory, stores the unique identification code of the chemical storage facility and a list of chemicals. A chemical identification tag, attached to the cover of a chemical container, stores the unique identification code of the chemical storage facility and chemical-related information. A mobile terminal, provided with an RFID reader, receives and outputs the unique identification code of the chemical storage facility, the list of the chemicals, and the chemical-related information.

Abstract: Disclosed is a mobile communication terminal having a camera function and a method of controlling a photographing process thereof. According to an embodiment of the disclosure, the mobile communication terminal comprises two buttons relating to the camera function positioned separately on a main body of the terminal. A first button is a photographing button that captures an image when on-state and a second button is a supporting button, provided the user chooses to activate this function. In this setup, the mobile communication terminal protrudes a camera lens or takes a photograph only when the first and the second buttons are in the on state. Accordingly, it is possible to reduce the possibility of dropping the terminal due to carelessness during photography, and to decrease the possibility of damaging the camera lens even when the terminal is dropped on the ground.

Abstract: A disk mounting hub has a disk-mounting face formed at one end as a truncated conical surface of revolution symmetric about a central axis. A cylindrical inner hub member is coaxial with the hub body outside diameter and the surrounding mounting face. The inner hub member is adapted to receive a planar disk with a central opening. The mounting face is disposed at a hub face angle (n/2+/?1) relative to the central axis. Hub face angle ? is selected so that a disk clamping force F applied to an inner disk portion surrounding the opening bends a portion of the disk interior to the hub inside diameter to conform with the conical disk-mounting face. This interior bending portion reduces or eliminates the tendency of the outer disk portion to form an excessive conning angle ?.
