摘要:
A receiver that receives radio signals, and a method for the same. The radio signals may be received by a plurality of antennas and then demodulated by respective converter devices, an estimated channel device estimates a channel for at least one antenna and at least one beam-forming device performs beam-forming on a selected main path signal from among the demodulated incident data signals. The output signals from the at least one beam-forming device are combined. The method of receiving the incident data signals may be accomplished by using space diversity.

A nitride semiconductor light emitting device includes n-type and p-type nitride semiconductor layers, and an active layer disposed between the n-type and p-type nitride semiconductor layers and having a stack structure in which a plurality of quantum barrier layers and one or more quantum well layers are alternately stacked. A net polarization of the quantum barrier layer is smaller than or equal to a net polarization of the quantum well layer. A nitride semiconductor light emitting device can be provided, which can realize high efficiency even at high currents by minimizing the net polarization mismatch between the quantum barrier layer and the quantum well layer. Also, a high-efficiency nitride semiconductor light emitting device can be achieved by reducing the degree of energy-level bending of the quantum well layer.

The present invention provides a door opening prevention device of a vehicle door outer handle. The door opening prevention device includes: a handle base having a lever mounting part; a lever rotatably mounted on the lever mounting part, having a return spring and having a locking slot formed in a shaft of the lever so as to pass through the shaft; a lever cover mounted on the lever mounting part so as to be provided outside the lever and having an elastic rotary member; a locking arm formed in the elastic rotary member, the locking arm being inserted into the locking slot when the elastic rotary member is rotated. The present device can reliably prevent the door from being opened in the event of a broadside collision.

A nitride semiconductor light emitting device includes n-type and p-type nitride semiconductor layers; an active layer disposed between the n-type and p-type nitride semiconductor layers and having a structure in which a plurality of quantum barrier layers and one or more quantum well layers are alternately stacked; and an electron blocking layer disposed between the active layer and the p-type nitride semiconductor layer. The electron blocking layer has a superlattice structure in which two or more layers having different compositions are alternately stacked. An absolute value of a net polarization mismatch between a material, the material having a composition corresponding to an average composition of the superlattice structure, and a quantum barrier layer adjacent to the electron blocking layer among the plurality of quantum barrier layers is less than ⅔ of an absolute value of a net polarization mismatch between AlxG1-xN(0

摘要:
Provided is a method and an apparatus for controlling a NEW MESSAGE alert in a portable wireless terminal. In a sender-side terminal, a NEW MESSAGE alert is set after a message is written. The NEW MESSAGE alert setting is designated at a header of the message. The message having the header with the NEW MESSAGE alert setting is transmitted. In a receiver-side terminal, a message is received and it is determined whether a NEW MESSAGE alert is designated at a header of the received message. If a NEW MESSAGE alert is designated at the header of the received message, the designated NEW MESSAGE alert is generated. Therefore, both a sending user and a receiving user can have equal authority over the NEW MESSAGE alert.

A composition for a photo-conductive layer and an electron transferring complex system on a color CRT panel having 1-(p-diethylaminophenyl)-1,4,4-triphenyl-1,3-butadiene as an electron donor and a thioxanthene derivative as an electron acceptor in an organic binder dispersion system have not only a high electron transferring capability but also a high electron generating capability so that it is not necessary to add a separate electron generating material.
