Title: Degaussing circuit using relay
Inventor: CHOI JU-HYUN
IPC: H04N9/29
Filed: 1988-05-04
Granted: 1991-05-18
Abstract: The circuit cuts off the current flowing  to  the  degaussing coil when turning on the power  switch  so  that  the  unnecessary degaussing effect is prevented. When turning on  a  master  switch (SW), but turning off the power switch, the AC power  flows  to  a degaussing coil (L2) of the CRT and a PTC  (PT1)  to  degauss  the CRT. At this time, relay switches (RS1-2) cuts off  the  AC  power applied to the primary coil of a transformer (T1) so that the  CRT is only degaussed. When turning on the power switch, the AC  power is induced at the secondary coil of the transformer, and turns  on the CRT. But the relays degaussing the CRT are turned off and  the current flowing through the PTC is cut off.

Abstract: The invention relates to monoclonal antibodies (MAbs) which bind with high specificity and avidity to water-soluble complexones such as ethylenediaminetetraacetate (EDTA) or diethylenetriaminepentaacetate (DTPA) and after complexation of EDTA or DTPA with metal ions retain their high avidity and specificity for these complexones. These MAbs can therefore be used, for example coupled to filters or other supports, for removing toxic heavy metals which are complexed with EDTA or DTPA. Furthermore, these MAbs are suitable as components of immunoassays (RIA, ELISA etc.) for the quantitative detection of EDTA and DTPA in aqueous solutions.

Abstract: A convergence control system for multiple vertical modes or formats, having respective rasters with different vertical heights, comprises a selector (4) for initiating operation in one of the available vertical modes, and a circuit (40) for generating convergence correction signals responsive to the selector. The correction signals are generated from known convergence correction values and by interpolation of the known values. The convergence correction values may be stored and sequentially processed by digital circuits and the interpolation may be undertaken by analog circuits. The circuit for generating convergence correction signals may comprise a digital data store (46) for different sets of convergence correction values, for generating selectable sets of correction signals for different vertical modes or formats, for example normal and overscanned modes. The sets of convergence correction values define different sets of grid lines and rows of horizontal scan lines. Adjacent ones of the grid lines are spaced from one another at different intervals for different vertical formats. The intervals between adjacent horizontal grid lines are greater for vertical formats having rasters with greater vertical heights. An interpolating circuit (40) for processing the known convergence correction values is responsive to the horizontal deflection circuit. The interpolating intervals can be adjusted to correspond to the horizontal scanning rate. The number of interpolating intervals is matched to the number of horizontal scan lines in each row. <IMAGE>
