    • A four-wheel-drive-vehicle driving force distribution apparatus has an auxiliary transmission mechanism for switching motive power transmitted to an input shaft at least between two levels, a high speed and a low speed, and transmitting the motive power to a main output shaft; a friction clutch for selectively transmitting the motive power of the main output shaft to an auxiliary output shaft; a ball cam mechanism for changing the pressing force of the friction clutch in a non-step manner; and a shift mechanism for shifting the auxiliary transmission mechanism. A clutch control mechanism is provided between a drive member fixed to an output shaft of a motor and a pinion gear and changes the clutch pressing force caused by the ball cam mechanism corresponding to clockwise rotation of the drive member performed by a motor starting from a control starting point. A shift control mechanism is provided between the drive member and a shifting cylindrical cam and alternately repeating switching between a H position and a L position of the auxiliary transmission mechanism in every counterclockwise reciprocating rotation of the drive member performed by the motor starting from the control starting point.
    • 四轮驱动车辆驱动力分配装置具有辅助传动机构,用于至少在两级之间切换传动到输入轴的动力,即高速和低速,并将动力传递到主输出轴 ; 用于选择性地将主输出轴的动力传递到辅助输出轴的摩擦离合器; 用于以非步进方式改变摩擦离合器的按压力的球形凸轮机构; 以及用于移动辅助传动机构的换档机构。 离合器控制机构设置在固定到电动机的输出轴的驱动构件与小齿轮之间,并且改变与由控制器开始的由电动机执行的驱动构件的顺时针旋转对应的由球形凸轮机构引起的离合器按压力 初始点。 在驱动构件和变速圆柱形凸轮之间设置有变速控制机构,并且在由控制开始的电动机的驱动构件的每个逆时针往复旋转中的交替重复切换辅助变速机构的H位置和L位置之间 点。

    • A broadcasting receiving apparatus includes a tuner to receive a broadcasting signal and output a reception signal selected therefrom, a demodulation portion to output a video audio signal by demodulating the reception signal from the tuner, an encryption portion to output an encrypted video audio signal by encrypting the video audio signal, a buffer portion to store one of the video audio signal from the demodulation portion and the encrypted video audio signal from the encryption portion, and a control portion to perform control in such a manner that, when the video audio signal needs to be encrypted in the encryption portion, the video audio signal is transferred in the form of first files each having a first capacity (m [KByte]), encrypted on a file-by-file basis in the encryption portion, and stored into a memory region in the buffer portion successively in units of the first capacity, and when the video audio signal need not be encrypted in the encryption portion, the video audio signal is transferred in the form of plural second files each having a second capacity (n [KByte], (m>n)) smaller than the first capacity on a file-by-file basis, and stored into the memory region in the buffer portion successively in units of the second capacity. It is thus possible to provide a receiving apparatus capable of preventing unauthorized copying of a video audio signal committed by tampering with flag information indicating the need for encryption.
    • 广播接收装置包括:接收广播信号并输出​​从其选择的接收信号的调谐器,解调部分,通过解调来自调谐器的接收信号来输出视频音频信号;加密部分,通过加密来输出加密的视频音频信号 视频音频信号,用于存储来自解调部分的视频音频信号之一和来自加密部分的加密视频音频信号的缓冲部分,以及控制部分,以使得当视频音频信号需要时 要在加密部分中加密,视频音频信号以加密部分逐个加密的第一容量(m [KByte])的第一文件的形式传送,并存储到 存储器区域以第一容量为单位连续地进行,并且当在加密部分中不需要加密视频音频信号时,视频音频 信号以逐个文件为基础以多个第二文件的形式传送,每个文件具有小于第一容量的第二容量(n [KByte],(m> n)),并且被存储到缓冲器中的存储器区域中 以第二容量为单位。 因此,可以提供一种能够防止通过篡改表示需要加密的标志信息来提交的视频音频信号的未经授权的复制的接收装置。
