    • An audio system, an audio apparatus, and a method for performing audio signal output processing are provided that prevent the occurrence of sound interruption of high-priority voice signal output, such as voice guidance for navigation. The audio system includes the audio apparatus communicatively connected to an electronic device for producing an audio signal and to an electronic device for producing a high-priority voice signal (voice guidance signal). When the voice guidance signal is received with the audio signal being received, the audio apparatus starts to perform a mixing operation of the voice guidance signal. If a request for switching a sample rate of the audio signal is made during the mixing operation, the audio apparatus suspends a sample-rate switching operation until the mixing operation is completed.
    • 提供了音频系统,音频装置和用于执行音频信号输出处理的方法,其防止诸如用于导航的语音引导之类的高优先级语音信号输出的声音中断的发生。 音频系统包括通信地连接到用于产生音频信号的电子设备的音频设备和用于产生高优先级语音信号(语音引导信号)的电子设备。 当接收到音频信号的语音引导信号时,音频装置开始执行语音引导信号的混合操作。 如果在混合操作期间进行切换音频信号的采样率的请求,则音频设备暂停采样率切换操作,直到混合操作完成。

    • A particle shielding element of a shape memory metal is installed between an electroconductive layer on the inner peripheral surface of a neck glass tube of a cathode-ray tube and a shield cup of an electron gun therein to close a gap between the neck glass tube and the shield cup for thereby guarding the electronic gun against invasion of particles, Before the particle shielding element is inserted into the neck glass tube, the element is deformed to reduce its outer diameter so that the element can be inserted into the neck glass tube without scratching the electroconductive layer. After the element has been installed in Position in the neck glass tube, the temperature therein is adjusted to cause the element to recovery to its initial shape into dust sealing engagement with the electroconductive layer.

    • In a magnetic floating type of super high speed transportation system using a linear synchronous motor system as its drive system in which a field magnet is carried on a train and a series of armature coils are provided along a track, a speed of a train is regulated under control of a frequency converter of the variable frequency and voltage type for supplying power to the armature coils. For the speed regulation, a relative position of the field magnet to the armature coils is detected to form a train of position detecting pulses. A reference frequency pattern with a frequency corresponding to a speed command is formed. A phase difference between the reference frequency pattern and the position detecting pulse train is detected. A propulsion force command of a linear motor is obtained by setting different limit values in the positive and negative parts of the phase difference signal. A sinusoidal current waveform pattern is formed in synchronism with the position detecting pulse train. By multiplying the current waveform pattern by the propulsion force command, a sinusoidal armature current pattern is obtained of which the frequency and the crest value are fixed. The cycloconverter is controlled so as to provide an armature current following the armature current pattern, whereby the vehicle speed accurately follows the speed command.
