Disclosed is a laminating frame employing a partial hologram, in which a photograph or picture is placed. The laminating frame includes a first laminating film of a desired dimension; a backing sheet adhered to the first laminating film and having a dimension slightly less than that of the laminating film; a partial hologram film disposed on the backing sheet and having a rim adhered to the first laminating film and a transparent window of a dimension slightly less than that of the backing sheet, wherein the transparent window is patterned with a plurality of dotted-hologram pixels and the rim is patterned on the upper and lower surfaces of the rim with a plurality of deeply colored hologram pixels; and a second laminating film adhered to the partial hologram film.

A method and an apparatus for resource allocation are provided. The method includes measuring the temperature of the mobile terminal, sending, when the measured temperature exceeds an upper threshold temperature set in advance, a request for reduced resource allocation to a corresponding base station, receiving a message for reduced resource allocation corresponding to the sent request from the base station, and performing communication according to reduced resource allocation. Hence, the temperature of the mobile terminal can be kept within an appropriate range.

The present invention discloses a device for measuring and monitoring electron density of plasma. The device includes a chamber filled with plasma having varying electron density; a frequency probe having transmission/receiving antennas and a pair of waveguides, one end of which is mounted in the chamber, for radiating and receiving electromagnetic waves; an electromagnetic wave generator electrically connected to one of the waveguides of the frequency probe for generating electromagnetic waves; and a frequency analyzer for scanning the frequency of received electromagnetic waves and analyzing the scanned frequency with respect to the amplitude of the received electromagnetic waves. Coupled to the rear end of the frequency probe is preferably a transfer unit having a hydraulic cylinder structure such that the frequency probe is moved in the chamber to detect the spatial distribution of electron density.

The present invention relates to an apparatus and method for monitoring an electron density and electron temperature of a plasma. The apparatus includes an electromagnetic wave generator that continuously transmits electromagnetic wave of a series of frequency bands, an electromagnetic wave transceiver connected to a plasma within a reaction container and electrically connected to the electromagnetic wave generator so that a frequency of the transmitted electromagnetic wave is correlated to the electron density and electron temperature of the plasma, the electromagnetic wave transceiver transmitting the electromagnetic wave, a frequency analyzer electrically connected to the electromagnetic wave transceiver, for analyzing the frequency of the electromagnetic wave received from the electromagnetic wave transceivers and a computer electrically connected to the electromagnetic wave generator and the frequency analyzer, for calculating a correlation between the electron density and electron temperature, and a corresponding electromagnetic wave based on a frequency band-based transmission command of the electromagnetic wave and the analyzed data.
摘要:
A flux distribution measuring apparatus measures distribution of flow rates of a flowable medium. The measuring apparatus includes thin metal wire(s) for scanning a flowable medium and lead wires connected to the thin metal wire(s), wherein a voltage difference is detected between adjacent lead wires while the measuring apparatus scans the flowable medium in the direction perpendicular to a flow path of the flowable medium. The voltage differences are generated due to temperature changes in the thin metal wire(s) while scanning the flowable medium having different flow rates. The measuring apparatus visualizes the distribution of flow rates of a flowable medium using a computer which receives and processes the voltage differences detected.
