    摘要： A ghost cancelling system which detects a horizontal scanning line containing the reference signals and extracts 8 fields reference signals from the horizontal scanning line. A final reference signal corresponding to the 8 fields reference signals is calculated by a specified calculation algorithm, and the system corrects the tap coefficient in response to the distinguished ghost signal using the final reference signal.

    摘要： In the storing mode, an operator section is operated to direct a parabolic antenna toward a broadcasting satellite and to select a desired channel. After the desired channel is seized, a predetermined label is input from a label input part. The satellite position and the selected channel are stored in a memory with the label attached thereto. When a search operation is performed, the direction of the antenna is gradually adjusted. Whenever the direction of the antenna is adjusted, the receiving frequency is scanned to receive each channel. When a signal is received by the frequency scanning, the type of the satellite is recognized depending on the odd or even group of channels and on whether the antenna is set to horizontally or vertically polarized wave reception. The type of the satellite as recognized, the antenna direction at that time, and the desired receiving channel transmitted from the satellite are stored into memory with a given label attached thereto. In the viewing mode, the stored label is designated and read out from the memory through the label input part. The antenna is directed toward a specific satellite to receive a desired channel, and is also put into a receiving state to receive the predetermined horizontally or vertically polarized wave.

    摘要翻译： 在存储模式中，操作部分被操作以将抛物面天线引向广播卫星并选择所需的频道。 在所需频道被占用之后，从标签输入部分输入预定的标签。 卫星位置和所选择的频道被存储在附加标签的存储器中。 当执行搜索操作时，天线的方向逐渐调整。 无论何时调节天线的方向，扫描接收频率以接收每个通道。 当通过频率扫描接收到信号时，根据信道的奇数或偶数组以及天线是否设置为水平或垂直极化波接收来识别卫星的类型。 所识别的卫星的类型，当时的天线方向以及从卫星发送的期望的接收信道被存储到具有附加到其上的给定标签的存储器中。 在查看模式下，通过标签输入部分指定存储标签并从存储器中读出。 天线指向特定的卫星以接收所需的信道，并且还被置于接收状态以接收预定的水平或垂直极化波。

    摘要： Lepidocrocite (.gamma.-FeOOH) with an large specific surface area and a uniform particle size is provided by a method comprising preparing a suspension of ferrous hydroxide at a pH of 6.5 to 7.5 by adding a ferrous salt solution with an alkali solution in an amount of 0.4 to 0.7 times the theoretical amount for converting all the ferrous salt to ferrous hydroxide, blowing an oxygen-containing gas into the suspension to form a seed crystal of .gamma.-FeOOH, completing the generation reaction of .gamma.-FeOOH by blowing an oxygen-containing gas into the suspension while adding an alkali solution to keep the pH of the suspension within a range of 3 to 5, in which an Si concentration of the suspensions for seed reaction and for generation reaction of .gamma.-FeOOH is controlled to be within 5 to 30 ppm.
