    • A meta data set correlated with position information is acquired from a server via a communication interface unit (202) or a broadcast interface unit (201). A current position information acquisition unit (208) acquires the current position information and a content processing unit (203) outputs a content list matched with the search condition including the current position information from the meta data set. When a display list is generated according to the content list, a content display control unit (204) compares the content list to the display list. When they coincide, the meta data generates a display list without changing the display method and displays the search result on a browser unit (205) according to the display list generated by the content display control unit (204).

    • Supplied with a power source, an output level of an oscillating circuit gradually increases until the oscillator circuit reaches its steady oscillation. A level monitor monitors the output level, and produces a control signal if the output level is less than a predetermined level. A current producing circuit receives the control signal and produces a boost current to increase a collector current at an oscillating transistor. The output level of the oscillating circuit suddenly increases as the collector current increases. After the output level of the oscillator reaches the predetermined level, the level monitor stops production of the control signal. Therefore, the boost current stops. As a result, the collector current of the oscillating transistor has a predetermined value dependent on the circuit structure of the oscillating circuit. Thus, only before the output level reaches the predetermined level, the collector current of the oscillating transistor is brought to an increased level, and after the output level reaches the predetermined level, the value of the collector current is decreased to a predetermined value. Therefore, the oscillator starts quickly, suppressing the increase of the power consumption even when the oscillator is intermittently driven.
    • 随着电源供电,振荡电路的输出电平逐渐增加,直到振荡器电路达到稳定振荡。 电平监视器监视输出电平,并且如果输出电平小于预定电平,则产生控制信号。 电流产生电路接收控制信号并产生升压电流以增加振荡晶体管处的集电极电流。 当集电极电流增加时,振荡电路的输出电平突然增加。 在振荡器的输出电平达到预定电平后,电平监视器停止产生控制信号。 因此,升压电流停止。 结果,振荡晶体管的集电极电流取决于振荡电路的电路结构具有预定值。 因此,只有在输出电平达到预定电平之前,振荡晶体管的集电极电流达到提高电平,并且在输出电平达到预定电平后,集电极电流值降低到预定值。 因此,即使振荡器间歇地驱动,振荡器也快速启动,抑制功耗的增加。

    • A differential amplifier produces a collector current of an output side transistor as an output current signal. In this case, a power supply voltage or a closer voltage to the power supply voltage is supplied to a collector terminal of the output side transistor. First and second current mirror circuits produce a current signal in response to the output current signal. The produced current signal passes through a resistor, a terminal of which is connected to a reference voltage. When the produced current signal passes through the resistor, a voltage drop from the reference voltage occurs at the resistor. By utilizing the voltage drop at the resistor, an output voltage changing in response to two output voltage signals is produced.
    • 差分放大器产生输出侧晶体管的集电极电流作为输出电流信号。 在这种情况下,向输出侧晶体管的集电极端子提供电源电压或与电源电压接近的电压。 第一和第二电流镜电路响应于输出电流信号产生电流信号。 产生的电流信号通过一个电阻,其端子连接到参考电压。 当所产生的电流信号通过电阻器时,在电阻器处产生从参考电压的电压降。 通过利用电阻器处的电压降,产生响应于两个输出电压信号而改变的输出电压。
