    • A printed-circuit board characteristic evaluation system is basically configured by an input device, a data processing device, a storage device and an output device. Herein, the input device inputs layout information representing an overall layout of a printed-circuit board installing at least one active component, from which layout information data regarding a power supply circuit is extracted and is stored in the storage device. The layout information data is converted to electric circuit information representing an equivalent circuit model with respect to a selected side of the printed-circuit board. Then, calculations are performed based on the layout information data to produce impedance characteristics with respect to the power supply circuit. A decision is made as to whether resonance is caused to occur in the power supply circuit on the basis of results of comparison of the impedance characteristics. The output device outputs the impedance characteristics as well as resonance information. If it is determined that resonance is caused to occur in the power supply circuit, the system changes the layout information, from which new layout information data is being extracted. In addition, a resonance suppression technique (e.g., installation of a decoupling capacitor) is applied to a certain point of the power supply circuit or a prescribed power terminal connecting position. Thus, the system is capable of performing evaluation as to whether printed-circuit boards are well designed to suppress variations of power voltages while inhibiting radiation of unwanted electromagnetic waves from occurring due to resonance of power supply circuits.

    • A vending machine capable of selecting any one of a first of a fourth mode which make it possible to carry out a commodity and a prize and a fifth mode which makes it possible to carry out only a commodity by a mode selecting device. In a state in which the fifth mode is selected, an ordinary commodity sale in which a selected commodity is executed based on insertion of coins or paper money, and pushing a commodity selecting button 4 is executed. In a state in which any one of the first to the fourth mode is selected, carrying-out of the prize from a prize carrying-out unit is executed in parallel with carrying-out of the commodity or independently.

    • The optical disk player is capable of correctly restarting to write data. Data protection means returns an optical pick-up from an interruption address to a synchronization starting address. The data protection means reads data from the synchronization starting address to the interruption address at a reading velocity equal to a former writing velocity. The data protection means restarts writing data from the interruption address if a phase of data read is synchronized with a phase of data to be written. The data protection means returns the optical pick-up to the synchronization starting address and reads data from there to the interruption address at a reading velocity slower than the former writing velocity so as to synchronize the phases if the synchronization is failed.
    • 光盘播放器能够正确重新启动以写入数据。 数据保护装置将光学拾取器从中断地址返回到同步起始地址。 数据保护装置以等于前一个写入速度的读取速度从同步开始地址读取数据到中断地址。 如果数据读取的相位与要写入的数据的相位同步,则数据保护装置重新开始从中断地址写入数据。 数据保护装置将光学拾取器返回到同步开始地址,并以比前一个写入速度慢的读取速度从那里读取数据到中断地址,以便在同步失败的情况下使相位同步。
