An antenna device for a portable terminal, which includes an antenna module disposed in an antenna jack of a terminal capable of TV service, the antenna module receiving broadcasting signals depending on mounting/demounting of an external antenna. The antenna device for a portable terminal includes an antenna module disposed along the outer circumference of the antenna jack, which receives broadcasting signals depending on mounting/demounting of the external antenna; an insulator module; and an antenna switch module. The external antenna provides a broadcast signal to the terminal when connection jack of the external antenna is joined with the antenna jack. The antenna module provides broadcast signals when the connection jack external antenna is separated from the antenna jack.

A system for processing data in a ubiquitous home network is provided. The system uses RF signals based on combination of the remote-controller and the ubiquitous sensor network (USN) technologies and integrally controls a plurality of control targets. Although the remote-controller is spaced relatively far apart from the control targets, the system can control the control targets only if the spaced distance is within the range of an RF signal. As well, the system can automatically control the control targets based on the information detected by the respective sensor nodes.

A method for reducing corrosion of carbon steel components, such as in a water-cooled nuclear reactor, having an oxide film layer formed on a surface thereof is provided. The method includes injecting a solution of a compound containing zinc into a supply of feedwater introduced into the nuclear reactor. The compound is decomposed under operating reactor thermal conditions to release atoms of zinc. The atoms of zinc are incorporated into the oxide film layer to increase a corrosion resistance of carbon steel.

A method for mitigating stress corrosion cracking of a component exposed to a high temperature water in a high temperature water system is provided. The method comprises the steps of lowering corrosion potential conditions to a desired low corrosion potential in the high temperature water environment; and introducing a first material comprising zinc into the high temperature water environment, such that the desired low corrosion potential facilitates transport of the first material into cracks in a structure communicative with the high temperature water environment.

In a feed-forward power amplifier, a main path amplifies a power level of an input signal to generate a path turning signal, an error path receives the input signal and controls a gain or a phase of a second order intermodulation component in the path turning signal to generate an intermodulation compensation signal, and a first synthesizer generates an output signal responsive to the path turning signal and the intermodulation compensation signal, achieving linearity.

The present invention relates to a bacterial effector protein which inhibits programmed cell death in eukaryotes and a nucleic acid molecule encoding such a protein. The present invention also relates to methods of suppressing programmed cell death in eukaryotes, delaying senescence in plants, and increasing protein expression in plants. The present invention further relates to a nucleic acid construct having a nucleic acid molecule encoding a first protein, which suppresses immunity by inhibition of programmed cell death in eukaryotes, coupled to a nucleic acid molecule encoding a second protein which is toxic when expressed in eukaryotes. Additionally, the present invention provides a method of stabilizing a transgenic plant transformed with such a nucleic acid construct. Finally, the present invention provides a method of treating subjects for a condition mediated by programmed cell death involving administering to the subject a bacterial effector protein which inhibits programmed cell death.

There is provided a digital data receiver for recovering at least one message word signal from a digital data frame. The digital receiver includes a digital FM demodulator for receiving frequency modulated signals, and for demodulating a dotting sequence signal, a word sync signal and a message word signal of each sub-frame which is in digital data frame, a dotting detector for detecting a dotting sequence signal of at least one sub-frame among the signals demodulated by the digital FM demodulator, based upon a predetermined signal which is shorter than the length of each dotting sequence signal of the each sub-frame, detecting means for determining the termination of receiving of the digital data frame after the dotting detector detects the dotting sequence signal, and for detecting a new digital data frame followed by the digital data frame; and a message processor means for recovering a message word signal in the digital signal frame which is related to the dotting sequence signal detected by the dotting detector. A method for recovering at least one message word signal from a digital data frame is also disclosed.
摘要:
A CDMA communication system including a variable rate vocoder transmits voice data without restriction of an encoding rate of the vocoder and transmits a signaling message so that voice quality of the CDMA communication system can be improved. If the signaling message is an emergent signaling message to be transmitted within a certain time, the encoding rate of the vocoder is restricted to a half rate, a quarter rate, or an eighth rate. Thus, the signaling message can be transmitted with the voice data within the certain time, so that delay of the signaling message transmission can be prevented.

Disclosed is a method for producing a highly concentrated, rice-derived lactic acid fermented product which tastes highly sweet and sour, and of which the flavor and texture are excellent. In this method, unground, grainy rice is gelatinized and then it is liquefied and saccharified by the primary treatment with .alpha.-amylase and glucoamylase. After sterilization, it is inoculated with lactic acid bacteria and undergoes a secondary treatment with .alpha.-amylase and glucoamylase. The glucose produced thereby continuously ferments to lactic acid. Finally, high concentrated lactic fermented product, tasting sweet and sour, and having excellent flavor and texture, is produced.
