摘要： A dielectric filter of which a characteristic is stable without a gastight casing. The dielectric filter's structure is comprised of an input, an output, a dielectric having a plurality of holes extending from a top to a bottom surface thereof, each of the holes being covered with a first conductive material, a second conductive material being electrically connected to the first conductive material at the bottom surface and unconnected to the first conductive material at the top surface, and an insulating weatherproof coating provided on the top surface.

摘要： A dielectric filter and a method of manufacture. The filter includes a block of ceramic material having one or more holes extending from a top surface to a bottom surface, each of which is interiorly covered with conductive material so as to form an inner conductive layer. The bottom surface and side surfaces of the block are also covered with bottom and side conductive layers electrically connected to the inner conductive layers at the bottom surface. The inner conductive layer is further connected to spaced apart top conductive layer portions provided on the top surface of the block surrounding each hole. The top layer portions are spaced from each other and have an oblique edge portion which is capacitively coupled with, and obliquely faces an upper edge portion of the side conductive layers, the oblique edge facilitating adjustment of the resonant frequency by removal of a predetermined amount of conductive material therefrom. In accordance with the method of manufacture of this filter, the filter is initially constructed to have a resonant frequency which is greater than that ultimately desired, and after measuring the resonant frequency initially obtained, a predetermined amount of conductive material is removed from the top conductive layer at a location along the oblique edge portion according to the required reduction in resonant frequency in order to reduce the resonant frequency to a desired value.

摘要： Composite units of an optical semiconductor device and a supporting substrate are disclosed, in which the rear surface of the optical semiconductor device is provided with one or more electrode patterns and the top surface of the supporting substrate is provided with one or more electrode patterns. The optical semiconductor device and the supporting substrate are fixed to each other by once melting and solidifying one or more solder bumps which intervene between the one or more electrode patterns provided on the rear surface of the optical semiconductor device and the one or more electrode patterns provided on the top surface of the supporting substrate. A good grade of accuracy in the mutual geometric position of the optical semiconductor device and the supporting substrate is obtained in a horizontal direction due to a phenomenon called "the self alignment results" in this specification, in which a molten metal is inclined to become a ball based on surface tension. Methods for mounting an optical semiconductor device on a supporting substrate with a good grade of accuracy in the mutual geometric position therebetween in the horizontal direction, based on the same technical principle, are also disclosed. To realize the foregoing results, each of the composite units of an optical semiconductor device and supporting substrate in accordance with this invention is given various structures specific to each of them, and each of the methods in accordance with this invention is given various steps or processes specific to each of them.
