摘要： In a transmission channel, such as a tape recorder, errors in code words usually occur in bursts. Further, it is usually possible to detect only some of the erroneous code words. To conceal undetected erroneous code words, concealment starts before, and continues after, a detected erroneous code word. Thus the undetected erroneous code words in an error burst have a high probability of being concealed.
摘要翻译：在诸如磁带录音机的传输通道中，代码字中的错误通常在突发中出现。此外，通常可以仅检测一些错误代码字。为了隐藏未检测到的错误代码字，在检测到的错误代码字之前和之后开始隐藏。因此，错误突发中未检测到的错误代码字具有被隐藏的高概率。

摘要： This invention relates to freeze protected livestock watering assemblies in general, and more specifically to a watering device, which incorporates a dual activated variable flow water supply valve structure, which is operatively connected to an apertured float arm to progressively increase the volume of water supplied to a drinking receptacle in proportion to the degree of depression of the float arm actuator.

摘要： A ferroresonant transformer includes a drive winding wound around a thin strip of magnetic material and coupled to a high frequency voltage source. The drive winding is resonated with a capacitance for saturating the core portion of the strip under the drive winding. A load winding, separated from the drive winding sufficiently to provide substantial magnetic decoupling, via air, for example, is resonated with a capacitance to saturate the core portion of the strip under the load winding for providing a regulated output voltage across the load winding.

摘要： Electrical contact to the substrate of a COS/MOS integrated circuit made with a four photomask process and having a well region of conductivity type opposite to that of the substrate is made by ion implanting through the bond pad openings to reconvert portions of the well to the opposite conductivity type thereby allowing contact to be made to the underlying substrate from the top surface.

摘要： A pyrogenic oxide is grown on a silicon wafer in a furnace by oxidizing hydrogen in the presence of an excess amount of oxygen as well as anhydrous hydrogen chloride to produce steam within the furnace. After growing a suitable pyrogenic oxide layer, the hydrogen and hydrogen chloride flows are turned off while the oxygen flow is continued to grow a dry oxide. A nitrogen anneal while the wafer is slowly pulled from the furnace completes the hybrid, radiation hard oxide layer.

摘要： The source and drain of an N-MOSFET can be brought closer together without substantially increasing capacitance and punch-through effects, by using a very high resistivity P-substrate, a moderately high resistivity P- type region in the channel zone and a thin but low resistivity surface-adjacent channel portion through which current flows. The P- type region and the surface-adjacent channel portion are ion-implantations. The P- type region extends deep enough into the substrate to shield the source from electrostatic coupling with the drain. Diffused, low reactance integrated circuit resistors can be made using the same principles.

摘要： The circuit protects the oxide of MOS devices from destructive breakdown by limiting the potential difference which can exist between two circuit nodes. By forming a protective circuit between each pair of nodes in the circuit, the range of voltages which can exist between any two nodes is predetermined, and the range can be fixed to prevent damage to the MOS devices. The protective circuit comprises a pair of diodes, a resistor, and a bipolar transistor.

摘要： The versatility of a character generator system, suitable for use in a television broadcast controller, is enhanced by employing a read/write character generator memory of a given overall storage capacity, rather than a ROM, and organizing the memory to store symbols in any selected single one of a given number of different predetermined dot-matrix sizes. Logic means responsive to the selected dot-matrix size are provided for digitally generating symbols for display on a display device exhibiting a television raster scan employing the particular alphabet of symbols then stored in the memory in the selected dot-matrix size.
