Abstract:
The present invention relates to a digital image signal recording/reproducing apparatus and the method thereof which can maintain a track spacing whereto a digital image signal is recorded during a long time mode in the same way as in the normal mode when the digital image signal is recorded on the recording medium, so that the crosstalks between channels caused by narrowed channel spacing of a tape can be prevented to thereby obtain an effect of a clear picture without a picture quality degradation.

Abstract:
In a transmission/reception apparatus in a base transceiver station (BTS), a commercial surface acoustic wave filter (SAW filter) can be used for suppressing transmission signals interfering with the reception path. By suppressing the interference signals, the reception sensitivity can be improved. In one embodiment of the present invention, an apparatus for processing trans-mission/reception signals in a BTS, comprises: a coupler connected to an antenna for providing reception signals; a duplexer having three terminals for routing the reception signals at a first terminal to a second terminal of the duplexer, and routing transmission signals at a third terminal of the duplexer to the first terminal, the coupler being further operative to provide the transmission signals at the first terminal to the antenna; and a narrow band low-noise amplifier connected to the second terminal for amplifying the reception signals from the second terminal, the narrow band low-noise amplifier being operative to suppress out-of-band interference signals such that reception sensitivity can be improved.
Abstract:
A low band converter for recording color signals converted in low band onto a video tape media of a VTR system. The inventive converter for use in a video tape recorder is capable of converting color signals thereof in low band, so that phase and frequency of the color signals may be correctly coincident with those of a horizontal synchronization signal in the VTR, by first demodulating and next modulating by way of synthesizing the color-differential signals from the color signals. An apparatus for achieving the converter includes a burst gate generator BGPG, a pulse synthesizer, a first delay circuit, a second delay circuit, a burst amplifier, a color signal demodulator, a first modulator, a second modulator, a mixer, a first detector and a second detector, a color gain converter ACC, a video recording amplifier, a color killer suited, and a low pass filter 100.
Abstract:
The present invention relates to a composition for preventing or treating an immune-related disease, and, more specifically, relates to a composition for preventing or treating immune-related diseases or oxidative-stress-related diseases in which the toxicity of an arsenic compound is effectively suppressed while the immune function boosting effect thereof is nevertheless maximised. The composition according to the present invention is useful in preventing or treating various immune-related diseases or oxidative-stress-related diseases since the composition reduces the toxicity of arsenic compounds, which traditionally have been difficult to use in clinical practice due to toxicity, while nevertheless maximising the pharmacological effects thereof.
