    • Disclosed is a three electrodes system cell for evaluation of performance of a molten carbonate fuel cell. A lower part of the reference electrode is fixed to a wet seal part of the single cell without penetrating a current collector plate and an electrode of the single cell. Preferably, the reference electrode comprises cured matrix slurry and powders of electrolyte stacked on the matrix slurry in the lower part thereof. Preferably, a diameter of an electrolyte-interchanging hole formed in a bottom of the lower part of the reference electrode is 1ψ. Preferably, an outer diameter of an alumina tube in the reference electrode is 6ψ. According to a three electrodes system cell for evaluation of performance of a molten carbonate fuel cell of the invention, it is possible to separately evaluate the performance of each electrode which cannot be evaluated by the prior method of evaluating the performance of the single cell. Particularly, contrary to the prior art, it is possible to prevent a crack of the matrix due to a physical shock and a heat shock resulting from the outflow and inflow of the supply gas, to reduce the gas leakage resulting from a decrease of adhesive strength between the matrix and the alumina tube and a heat shock due to the gas leakage, to improve the problem of electrolyte depletion and to reduce the physical defects resulting from a size of the reference electrode. Accordingly, it is possible to clearly measure the variation of the performance of each electrode while reducing the physical errors to the highest degree, to provide an exact criterion regarding the factor influencing on the variation of performance of the single cell when evaluating the performance of the single cell having 100 cm2 of large area, and to directly evaluate the performance of the molten carbonate fuel cell.

    • A track jump method for an optical recording/reproducing medium is provided. In the track jump method, once a track jump command is input, a track jump operation is held until a falling edge of a header mask signal is detected. The track jump starts at the falling edge of the header mask signal and ends before a rising edge of the header mask signal so that a TZC signal is not influenced by a header during the track jump. Therefore, the track jump can be exactly and stably performed. In particular, when the track jump command is input, a PLL of a wobble signal is inhibited, and a PLL-wobble signal is held to a previous value obtained before the track jump is performed, during the track jump, or a header mask signal is generated using a read channel signal which is not influenced by a wobble period, until a wobble signal becomes stable after a trackjump. During a normal servo, a header mask signal is generated using a PLL-wobble signal to mask a header area. Therefore, a header area coming first after the trackjump is completed can be stably masked, thereby preventing a system from being unstable due to a header during the track jump.
    • 提供了一种用于光学记录/再现介质的轨道跳跃方法。 在轨道跳跃方法中,一旦轨道跳转命令被输入,轨道跳转操作被保持,直到检测到标题屏蔽信号的下降沿。 磁道跳转在标题屏蔽信号的下降沿开始,并且在标题屏蔽信号的上升沿之前结束,使得在轨道跳跃期间TZC信号不受标题的影响。 因此,可以准确稳定地进行轨道跳跃。 特别地,当输入轨道跳转命令时,禁止摆动信号的PLL,并且将PLL摆动信号保持为在轨道跳跃期间执行轨道跳跃之前获得的先前值,或者标题屏蔽信号 使用不受摆动周期影响的读通道信号产生,直到摆动信号在轨迹之后变得稳定。 在正常伺服期间,使用PLL摆动信号产生标题屏蔽信号以屏蔽报头区域。 因此,可以稳定地掩盖在轨迹开始完成之后首先出现的首标区域,从而防止系统在轨道跳跃期间由于头部而不稳定。
