    • A portable electronic device has a display part (16) which can display a plurality of selection items; an operation part (12) for selecting the selection item displayed on the display part (16); and a control part (18) which switches the selection item to other selection item selected from the selection items displayed on the display part (16) by operation of the operating part (12). The control part (18) has a function of changing the switching speed of the selection item selected by the operation of the operation part (12) in accordance with display mode of each of the selection items displayed on the display part (16). Thus, usability is improved by, for instance, changing a scroll speed for the continuous selection operation.
    • 便携式电子装置具有能够显示多个选择项目的显示部件(16) 用于选择显示在显示部分上的选择项目的操作部分; 以及控制部(18),其通过操作部(12)的操作将选择项切换到从显示部(16)上显示的选择项中选择的其他选择项。 控制部(18)具有根据显示在显示部(16)上的各选择项的显示模式,改变由操作部(12)的动作所选择的选择项的切换速度的功能。 因此,通过例如改变用于连续选择操作的滚动速度来提高可用性。

    • A delay-line demodulator for demodulating a differential quadrature phase shift keying (DQPSK) signal is provided. The demodulator includes two Mach-Zehnder interferometers individually comprising two waveguides having different lengths therebetween and through which a light signal branched from the DQPSK signal propagates, respectively. A phase of the light signal propagating at one of the waveguides is delayed as compared to a phase of the light signal propagating at another one of the waveguides, wherein a divergence amount of polarization is adjusted by driving sets of heaters that are facing each other and sandwiching a half wavelength plate therebetween.
    • 提供了用于解调差分正交相移键控(DQPSK)信号的延迟线解调器。 解调器包括两个马赫 - 曾德干涉仪,它们分别包括两个不同长度的波导,分别从DQPSK信号分支的光信号通过该波导传播。 与在另一个波导上传播的光信号的相位相比,在波导中的一个传播的光信号的相位被延迟,其中通过驱动彼此面对的加热器组来调节偏振的发散量, 在其间夹着半波片。
