摘要： A packet-relay unit 100 including a first interface unit (110), a second interface unit (120), and a function-setting switch (130). The second interface unit (120) includes a classifying unit (121), a priority control unit (122), and a transceiving unit (123). When the function-setting switch (130) sets a “QoS function” as “operative”, the classifying unit (121) transfers packets transferred from the first interface unit (110) to the priority control unit (122). The priority control unit (122) provides priority control over the transferred packets such that the transferred packets are preferentially treated at a wireless zone connected to the second interface unit (120), whereby the priority-controlled packets are transferred to a transceiving unit (123) from the priority control unit (122). When the function-setting switch (130) sets “the QoS function” as “inoperative”, the classifying unit (121) transfers the transferred packets directly to the transceiving unit (123).

摘要： An amplifier circuit for amplifying a change in a resistance value of a magnetic resistance element is formed by connecting a first and a second current mirror circuits having the same structure in cascode, so that a voltage change is amplified without using a capacitive coupling. Hence, a high-pass filter is not created as a parasitic circuit, whereby a gain is maintained high in the low frequency region and a low frequency characteristic is excellent. Further, since control electrodes of transistors which form each current mirror circuit are grounded through the capacitance, a noise is reduced without using a conventional feedback circuit. This eliminates an influence of the feedback circuit over a high frequency characteristic, and therefore, a high frequency characteristic becomes excellent.
摘要翻译：通过将具有相同结构的第一和第二电流镜电路串联连接形成用于放大电阻元件的电阻值变化的放大器电路，从而在不使用电容耦合的情况下放大电压变化。因此，不产生高通滤波器作为寄生电路，从而在低频区域中增益保持较高，并且低频特性优异。此外，由于形成每个电流镜电路的晶体管的控制电极通过电容接地，所以在不使用常规反馈电路的情况下，噪声降低。这消除了反馈电路对高频特性的影响，因此高频特性变得优异。
