    摘要： The present invention relates a diagnosis device for detecting an end of lamp life of a lamp, a diagnosis method, and a lamp ballast circuit using the same. The diagnosis device generates a reference lamp voltage by adding a predetermined reference voltage to a distributed voltage corresponding to a lamp voltage applied to a lamp and generates an integrated lamp voltage by integrating the reference lamp voltage. The diagnosis device compares the integrated lamp voltage with a normal range that an integrated lamp voltage has when the lamp is in a normal state.

    摘要： An antenna system measurer (110a, 110b, 110c) for a repeater and a base station (10) measures powers of a progressive wave and a reflected wave of a transmit/receive antenna, and transmits measured results to a monitoring server (200) in a radio data format such as an SMS message. The monitoring server (200) receives the radio data, identifies a repeater and a base station from sender information of the radio data, and calculates a VSWR based on the measured values. The VSWR is modified based on characteristics of the base station such as length and substance of feeders from a base station identifier corresponding to the sender information. According to the present invention, the remote antenna system is monitored in real-time without visits or installation fees, and a plurality of repeaters and base stations is managed in a combined manner.

For this purpose, a base station device has a reverse processor for processing a reverse signal received through the antenna array, a forward fading information extraction unit for extracting forward fading information from the received reverse signal, a beam formation controller for generating a weight vector for formation of a transmission beam using the forward fading information and the received reverse signal, and a forward processor having a transmission beam generator for generating a transmission beam for a transmission message based on the weight vector. A mobile station device has a forward processor for processing a received forward signal, a forward fading estimator for estimating forward fading information of the forward signal for each path, a forwarding fading encoder for combining the estimated forward fading information and encoding the combined forward fading information, and a reverse processor for multiplexing the encoded forward fading information with a transmission message and feeding back the forward fading information in the multiplexed signal to a base station.

    摘要： A method of forming a tungsten plug in a semiconductor device includes forming a contact hole in an insulating layer, forming a contiguous titanium layer in the contact hole and on the insulating layer, forming a titanium nitride layer on the titanium layer. forming a thin tungsten layer of about 50 angstroms or less on the titanium nitride layer by CVD (chemical vapor deposition), annealing the structure once the thin tungsten layer has been formed, and depositing additional tungsten by CVD to completely fill the contact hole. The titanium nitride layer can be formed by a discrete CVD process or as a result of the annealing process. Forming a thin tungsten layer by CVD before the contact hole is completely filled in with tungsten is used to stabilize the titanium layer. For instance, a small amount of fluorine from the source gas of the thin tungsten layer diffuses into the titanium layer. Annealing the structure then diffuses the fluorine uniformly throughout the titanium layer to the point where additional fluorine from the subsequent CVD process of depositing tungsten can not diffuse into the titanium layer This, in turn, prevents a reaction at the titanium layer from taking place at the time the contact hole is filled in completely with tungsten. Accordingly, the titanium nitride layer remains adhered to the insulating layer.
