摘要： A compact frequency multiplier can perform high-degree frequency multiplication and can be incorporated in a wireless device. The frequency multiplier includes an input terminal for inputting an input signal, a first resonant circuit resonating with the frequency &ohgr; of the input signal, a second resonant circuit and an idler circuit, which resonate with the frequency n·&ohgr; that is, n times the frequency of the input signal, a variable reactor such as a varactor diode, coupling-adjusting capacitors, a bias resistor, and an output terminal for outputting multiplied output signals. In one embodiment, the frequency multiplier is a current-excitation type. The first resonant circuit and the second resonant circuit, each of which is constituted of an LC series resonant circuit, are connected in series between the input terminal and the output terminal. In addition, a parallel circuit constituted of the idler circuit and the varactor diode is connected to a connection point between the first and second resonant circuits and the input terminal and the output terminal.

摘要： A circuit board holds a line of light emitting elements mounted thereon. The light emitting elements are at a predetermined height from the surface of the circuit board. A rod lens array longitudinally extends and forms images of the light emitting elements on a photoconductive body such that the images and the light emitting elements form pairs of conjugate points with respect to the rod lens array. A holder holds the rod lens array relative to the light emitting elements. Supporting members are mounted to the holder at locations along a length of the rod lens array and hold the rod lens array relative to the circuit board so that the images form a substantially straight line on the photoconductive body. Each of supporting member supports a part of the rod lens array relative to the circuit board. The supporting member has a first reference portion and a second reference portion, the first reference portion abutting a lower surface of the rod lens array and the second reference portion abutting the surface of the circuit board on which the light emitting elements are carried. The supporting member of different heights may be assembled to the holder along the length of the rod lens array so that any warp and/or distortion of the base is accommodated, thereby allowing images of light emitting elements are on a very straight line.

摘要： An LED head for illuminating a surface of a photoconductive body includes an LED circuit board, lens assembly (SLA), SLA holder, base, and engagement member. The LED circuit board has LED arrays mounted thereon. The lens assembly has an optical axis and focuses light emitted from the LED arrays on the surface of the photoconductive body. The SLA holder has two opposing walls to hold the lens assembly therebetween. One of the opposing walls has a first reference surface with which the optical axis of the lens assembly is in a predetermined positional relation and urges the lens assembly against the other of the opposing walls. The base houses the LED circuit board and the SLA holder therein. The base has a second reference surface such that the optical axis is placed in position with respect to the LED arrays when the second reference surface is in intimate contact with the first reference surface. An engagement member holds the holder and the base together so that the first and second reference surfaces are in intimate contact with each other.
