摘要:
Methods and structures are disclosed which realize high Q inductors to provide on-chip noise matching of microwave monolithic integrated circuits, such as low noise amplifiers and output matching networks for power amplifiers. High Q inductors, of typically 6nH, are devised by using the inductance of package leads, bondwires, electronic board trace wires and transmission lines and other components in various configurations. These and other components are serially connected starting from a chip pad, representing a circuit node, to a circuit input on a that electronic board.
摘要:
The present invention provides a method of supporting and driving an electro-photographic photoreceptor in which total deflection can be improved and vibration sound due to the total deflection can be prevented, and an imaging apparatus realizing the method. A sliding bearing 3 fixed to a supporting member 2 consisting of a box member is fitted into an inner circumferential surface of an end portion of a cylindrical substrate 1 in the axial direction thereof. An annular driving member 4 is fitted into the other end portion of the cylindrical substrate 1 in the axial direction thereof. A threaded hole is provided at the central portion of the driving member 4. When a screw 5 is inserted into the threaded hole, the driving member 4 is deformed in an outer diametrical direction thereof and fixed to the inner circumferential surface of the cylindrical substrate 1. The driving member 4 is caused to be rotated by a driving source (not shown) which is connected to the driving member 4 via a gear 8. The cylindrical substrate 1 is interlocked with the rotation of the driving member 4 and is thereby rotated. Since the cylindrical substrate 1 is directly supported by the sliding bearing 3 and the driving member 4, very little deflection is caused to the substrate 1 so that the generation of vibration sound due to the deflection can be prevented.

A microwave bandpass filter having a wide bandwidth, low loss, and yet which requires only a relatively small circuit area. A generally annularly shaped unit-wavelength resonator is formed on a dielectric substrate, disposed between input and output matching circuits. The unit-wavelength resonator is formed by a pair of semi-annular strips disposed opposite one another and having opposing stubs defining therebetween a gap of predetermined width.
