摘要:
An amplifying circuit with a bypassing function includes an input terminal to which a signal is input from an antenna, an amplifier connected to the input terminal, a first inductor connected between the input port and a ground, and a bypass circuit connected between the input terminal and the output port of the amplifier. The bypass circuit includes a first port connected to the input terminal, a second port connected to the output port of the amplifier, a switch, a capacitor, and a second inductor. The switch is connected in series between the first and second ports. The capacitor is connected in series to the switch between the first and second ports. The second inductor is connected in series to the switch and the capacitor between the first and second ports. The amplifying circuit does not reduce power of a signal drastically even when the signal passes through the bypass circuit, as compared to passing through the amplifier, thus maintaining a profile of a propagation property unchanged and provide preferable transmission quality.

A signal branching filter according to the invention is a signal branching filter connected to a network having at least four terminals. The signal branching filter includes a first line one end of which is connected to a first terminal of the network, a second line one end of which is connected to a second terminal of the network, a third line one end of which is connected to a third terminal of network, and a fourth line one end of which is connected to a fourth terminal of the network. The other end of the first line and the other end of the second line are connected to each other at a first node, and the other end of the third line and the other end of the fourth line are connected to each other at a second node. When a signal is received from the first node, a phase difference between a phase of a signal appearing on a second node side of the third line and a phase of a signal appearing on a second node side of the fourth line is almost 180°±360°*n is an integer equal to or larger than 0).

Disclosed is an apparatus for supporting an electric blower of a vacuum cleaner, comprising a front supporting member positioned between the front surface of the electric blower and a housing of the vacuum cleaner and a rear supporting member positioned between the electric blower and the housing thereof. The rear supporting member is fixed to the electric blower and the housing to prevent the electric blower from being moved in its thrust direction. The rear supporting member is fixed thereto such that one end portion thereof is fixedly secured to the rear portion of the electric blower and a groove portion formed on the periphery of the rear supporting member is engaged with a fixing member protrudingly provided on the housing. The front supporting member is formed so that at least the cross section of a portion thereof positioned between the front surface of the electric blower and the housing of the vacuum cleaner has a wedge-like configuration.
