Title: Ghost cancelling method
Inventor: KIM INN-CHOL
IPC: H04N5/21
Filed: 1993-09-08
Granted: 1996-10-02
Abstract: The method improves the ghost cancellation by correcting a phase reversion of the input signal occurring from the channel characterization. The method comprises the steps of: carrying out the channel characterization; storing a first relative peak value in a second variable; storing a difference of the absolute values of the first and second variable; comparing a predetermined threshold value with the second variable stored to check the CC condition; cancelling the ghost included in the TV signal if the second variable value is larger than the predetermined value; and carrying out a new channel characterization to get a new filter coefficient and cancelling the ghost included in the received TV signal using the new filter coefficient.

Title: Automatic degasser
Inventor: SHIN MAENG-KOO
IPC: F04B49/00
Filed: 1993-09-23
Granted: 2000-12-15
Abstract: PURPOSE: An automatic degasser is provided to prevent waste of power consumption and to lengthen the life time of a vacuum pump by stopping the vacuum pump automatically if atmospheric pressure in a vacuum chamber is lower than a reference value and then operating the vacuum pump if the atmospheric pressure is higher than the reference. CONSTITUTION: An automatic degasser includes a power unit(10), a power supply unit(40), a pressure sensor(50), a control unit(60), a vacuum pump(20), a solenoid valve(70) and a vacuum chamber(30). The vacuum chamber has a liquid tube(31). The vacuum pump and the solenoid valve are stopped as the vacuum chamber keeps vacuum by the vacuum pump. If the vacuum chamber keeps vacuum by continuous pressure falling, bubbles contained in a liquid flowing through the liquid tube are discharged out of the vacuum pump through a thin film of the liquid tube. The bubbles are exhausted to outside by the vacuum pump. Thereby, the bubbles contained in the liquid are eliminated by the automatic degasser and injected into a column by the pump to analyze various kinds of element precisely.

Granted: 1997-03-05
Abstract: A method of forming an oxide layer of a semiconductor device is provided, in which a wafer on which the oxide layer will be formed is loaded in an oxidation tube and the oxide layer is grown through pre-oxidation, main oxidation and post-oxidation processes. The main oxidation process uses the mixture of N2O gas and NH3 gas, and the pre-oxidation and post-oxdiation processes, performed before and after the main oxidation, use only N2O gas. Addition of the pre-oxidation and post-oxidation prevents the wafer from being nitrided before oxidized and keeps the interface characteristics from being deteriorating due to H of NH3 which is penetrated into the oxide layer. Accordingly, high quality oxide layer can be obtained by simultaneously controlling nitrogen introduction and oxidation.

Pour un récepteur à N=4 ou N=2 à double sur-échantillonnage, les matrices 4x4 résultantes sont divisées en sous-matrices blocs 2x2, inversées et reconstruites en une matrice 4x4. Des computations communes sont trouvées et des computations répétées sont éliminées par améliorer l'efficacité.
