    • A method of operating a fuel cell including a fuel electrode, an oxidant electrode, and an electrolyte layer having hydrogen ion conductivity sandwiched between the fuel electrode and the oxidant electrode, so that the fuel cell generates electricity as a result of an electrochemical reaction between a fuel and an oxidant. Each time the fuel cell is started from a non-operating condition, the fuel is supplied to the fuel electrode with the fuel electrode and the oxidant electrode electrically interconnected to produce hydrogen at the oxidant electrode by provoking electrochemical reactions expressed by the chemical equations H2→2H++2e− and 2H++2e−→H2 at the fuel electrode and the oxidant electrode, respectively, reducing oxides on the oxidant electrode, using the hydrogen produced at the oxidant electrode. Then, the oxidant is supplied to the oxidant electrode to begin normal continuing operation of the fuel cell.

    • This invention aims to provide a method and apparatus for detecting a synchronization shift in which the synchronization shift between an original image and a reproduced image can be accurately detected even if noises are generated by a video codec or the like. An original image sent out from an image source 1 has a sine wave for synchronization overwritten thereon in a frame memory. The image on which the sine wave has been overwritten is decoded in a codec and stored in another frame memory. The two images srored. in two frame memories are simultaneously started to be read out. From the image from the other frame memory, only the sine wave is extracted in a notch filter, subjected to an offset correction in an adder, and inputted to asynchronization shift detecting unit. The synchronization shift detecting unit uses the sine wave to detect line, frame and horizontal pixel shifts. Since a sine wave is used as a synchronization marker and only the sine wave is extracted in the notch filter, the synchronization shift can be accurately detected.
    • 本发明的目的在于提供一种用于检测同步偏移的方法和装置,其中即使通过视频编解码器等产生噪声也能够准确地检测原始图像和再现图像之间的同步偏移。 从图像源1发送的原始图像在帧存储器中具有用于同步的正弦波。 已经覆盖了正弦波的图像以编码解码器解码并存储在另一个帧存储器中。 这两个图像被扫描。 同时开始在两帧存储器中读出。 从另一个帧存储器的图像中,只有在陷波滤波器中提取正弦波,在加法器中进行偏移校正,并输入到异步移位检测单元。 同步移位检测单元使用正弦波来检测线,帧和水平像素移位。 由于使用正弦波作为同步标记,并且仅在陷波滤波器中提取正弦波,因此可以准确地检测同步偏移。

    • A corresponding MB2 for the left sequence is determined from the parallax vector of a coding-object MB1 of the frame Bi for the right sequence. The motion vector {circle around (2)} of the corresponding MB2 is used as an origin of the search area for finding the motion vector of the coding-object MB1. As an alternative, the motion vector {circle around (3)} of MB3 adjacent to the coding-object MB1 is used as an origin of the search area for finding a motion vector of the coding-object MB1. As another alternative, the motion vector {circle around (2)} or {circle around (3)}, whichever is higher in utility evaluation, is used as an origin. As a result, both the search area and the circuit size for detecting a motion vector can be reduced. This configuration provides a stereo video data motion vector coding apparatus small in circuit size and capable of detecting a motion vector with high accuracy.
    • 从右序列的帧Bi的编码对象MB1的视差矢量确定左序列的对应MB2。 使用对应的MB2的运动矢量{round(2)}作为用于找到编码对象MB1的运动矢量的搜索区域的原点。 作为替代,将与编码对象MB1相邻的MB3的运动矢量{round around(3)}用作用于找到编码对象MB1的运动矢量的搜索区域的原点。 作为另一种选择,使用运动矢量(围绕(2)}或{圆周(3)}(以公用事业评估较高者为准)作为起点。 结果,可以减少用于检测运动矢量的搜索区域和电路尺寸。 该配置提供了一种电路尺寸小且能够高精度地检测运动矢量的立体视频数据运动矢量编码装置。

    • A karaoke apparatus is constructed for playing a karaoke song according to song data jointly with a first vocal part and a second vocal part. In the karaoke apparatus, a generator device processes the song data to produce an orchestral accompaniment sound during the course of play of the karaoke song. A first input device collects a first singing voice which is physically sung along the orchestral accompaniment sound to fit with the first vocal part. A second input device collects a second singing voice which is physically sung along the orchestral accompaniment sound to support the first singing voice. An adjuster device adjusts at least a pitch of the second singing voice collected by the second input device according to reference data contained in the song data so as to fit the second singing voice with the second vocal part. A mixer device mixes the first singing voice collected by the first input device and the second singing voice fed from the adjuster device together with the orchestral accompaniment sound to thereby effect play of the karaoke song. The first singing voice may be of a main melody, while the second singing voice may be of a harmony melody or a back chorus.
