    摘要: After establishing a connection between an ATU-C and an ATU-R and having a state where data communication is enabled, the ATU-R checks a packet that flows through a network at the user side. When there is no packet addressed to the ATU-R for a predetermined time period, the ATU-R transmits, to the ATU-C, a request to transition to an energy-save mode. The ATU-C and AUT-R determines a parameter to be used for the energy save mode, the parameter enabling a number of carriers and/or transmission power to be decreased compared to the ones in a normal mode. Using the determined parameter, a state in which data communication is enabled is maintained.

    摘要: In a &pgr;/2 phase shifter, first and second signals and first and second inverted signals are produced based on input signals. The first and second signals have the same amplitude and are out of phase from each other, and the first and second inverted signals respectively correspond to the first and second signals with their respective phases inverted. A first output signal is produced by adding the first signal and the second signal, and a second output signal is produced by adding the first signal and the second inverted signal. Since the first and second signals have the same amplitude, the first output signal and the second output signal respectively correspond to diagonal lines of a rhombus formed by a vector representing the first signal and a vector representing the second signal. Accordingly, the phase difference between the first and second output signals of the &pgr;/2 phase shifter is accurately set to &pgr;/2 even when the phase difference between the first and second signals is not &pgr;/2.

    摘要: Between resistors 13, 14 and an NPN bipolar transistor 12 are interposed PNP bipolar transistors 21, 22 forming a current mirror 20 that uses a collector current of the NPN bipolar transistor 12 as a reference current, and determines a collector current of an NPN bipolar transistor 11. This makes possible to design a size ratio A of the PNP bipolar transistors 21, 22 so as to approximate a voltage drop &Dgr;Vb to a value close to zero, and to suppress the voltage drop &Dgr;Vb of the base voltage Vb accordingly to achieve a high power output and high efficiency when a high frequency input signal Pin increases and generates a base rectified current.

    摘要: Disclosed is a conductive antireflection film comprising a laminate structure consisting of a conductive layer and an insulating covering layer covering the surface of the conductive layer and a conductive member connected at one end to the conductive layer and exposed at the other end to the outside. The conductive member is brought into contact with an electrolytic solution so as to control the state of the metal contained in the conductive layer, making it possible to prevent effectively an electromagnetic wave from leaking to the outside and to obtain a clear image of a high contrast.
