    • An IR keyboard (1) generates key code information corresponding to an operated key, adds break flag information indicating whether the key is "in operation" or "not in operation" to the key code information as the operating state information of the key, adds terminator code information indicating the completion of the key code information corresponding to each key operation to the end of the key code information, and transmits the key code information, break flag information, and terminator code information on infrared signals from a light emitting section (11). A light receiving section (2) receives the infrared signals from the section (11) and inputs the key operation information of the IR keyboard (1) to a computer system (3). When the section (2) fails to receive signals because the break flag information added to the key information contained in the infrared signals transmitted from the section (11) indicates that the key is in operation, the section (2) starts time counting operations at the fault occurring time and, if the section (2) can receive signals within a prescribed counted time, it performs control as if signals were continuously received.
    • IR键盘(1)产生与操作的键对应的键码信息,将表示键是“正在操作”还是“不操作”的断点标志信息添加到键代码信息作为键的操作状态信息 指示与密钥代码信息的结尾对应的每个密钥操作的密钥代码信息的完成的终止符代码信息,并且从发光部分(11)发送关于红外信号的密钥代码信息,中断标志信息和终止符代码信息 )。 光接收部分(2)接收来自部分(11)的红外信号,并将IR键盘(1)的键操作信息输入到计算机系统(3)。 当由于从部分(11)发送的红外信号中包含的密钥信息中添加的中断标志信息指示密钥正在运行时,当部分(2)不能接收信号时,部分(2)开始计时操作 故障发生时间,如果部分(2)能够在规定的计数时间内接收信号,就像继续接收信号一样进行控制。

    • A matrix switcher which is used in the switcher system of a broadcasting station, connects a plurality of input lines with a plurality of output lines at arbitrary points, and output supplied source video signals from a desired output line. The switcher is specially constituted so that the input corresponding to each output is easily confirmed. On an operation panel (40) of the switcher system which connects the inputs with outputs by arbitrarily switching the inputs and outputs, there are provided cross point buttons (40A) which respectively select a plurality of inputs and a plurality of outputs, a source name display section (40N) on which inputted source names are displayed, delegation buttons (40A) which respectively select the outputs, and an output source name display section (45N) on which selected and outputted source names are displayed. When one of the delegation buttons (45A) selects a prescribed output, one of the cross point buttons (40A) changes the source name displayed on the displaying section (45N) to the source name newly selected by one of the cross point buttons (40A). Therefore, all source names currently selected for each output can be confirmed directly at a look.
    • 在广播台的切换器系统中使用的矩阵切换器将多条输入线与任意点的多条输出线连接,并从期望的输出线输出提供的源视频信号。 切换器是特别构成的,因此可以容易地确认与每个输出相对应的输入。 在通过任意切换输入和输出将输入与输出连接的切换器系统的操作面板(40)上,提供分别选择多个输入和多个输出的交叉点按钮(40A),源名称 显示输入的源名称的显示部分(40N),分别选择输出的授权按钮(40A)以及显示选择和输出的源名称的输出源名称显示部分(45N)。 当其中一个委托按钮(45A)选择规定的输出时,交叉点按钮(40A)中的一个将显示部分(45N)上显示的源名称改变为由交叉点按钮(40A)中的一个新选择的源名称 )。 因此,目前为每个输出选择的所有源名可以直接确认。

    • Before actually performing reproduction, the time from the reference phase position in one cycle of the rotating drum (1) to the time when the head detects a timing signal of each recording area in the tape-like recording medium is measured, an average of the measured times for each recording area is calculated and a reference value is generated based on the maximum and minimum of the calculated averages of the recording areas. During reproduction, the time from the reference phase position to the time when the head detects a timing signal for the tape-like recording medium is measured. Based on the result of comparison between the measured time and the reference value, the relative speed between the travel speed of the tape-like recording medium and the rotating drum rotating speed is controlled. This control enables satisfactory tracking over the entire area of the track even when the relation between the scan locus of the reproducing head and the track geometry is not ideal, thus improving the reliability of the digital data storage using a tracking controller for this tape-like recording medium.
    • 在实际进行再现之前,测量从旋转滚筒(1)的一个周期中的基准相位位置到头部检测到带状记录介质中每个记录区域的定时信号的时间的时间, 计算每个记录区域的测量次数,并且基于计算的记录区域的平均值的最大值和最小值来生成参考值。 在再现期间,测量从基准相位位置到头部检测带状记录介质的定时信号时的时间。 基于测量时间和参考值之间的比较结果,控制带状记录介质的行进速度与旋转滚筒转速之间的相对速度。 即使当再现头的扫描轨迹与轨道几何形状之间的关系不理想时,该控制也能在轨迹的整个区域上令人满意的跟踪,从而提高使用该带状跟踪控制器的数字数据存储的可靠性 记录介质。
