    摘要: A dielectric filter utilizing a plurality of serially coupled resonators having attenuation maximums at the lower side or higher side, or both, of a pass band frequency region. The filter may include an input element which is coupled with both of a first resonator and a second resonator, and may also include an output element which is coupled with both the last and the next-to-last resonator. In the dielectric filter, it is not necessary to provide an external wire connection to generate such attenuation maximums.

    摘要: A dielectric resonator device with a higher Q and a lower cost and which makes it possible to effect spatial coupling between predetermined dielectric columns of adjacent dielectric resonators without using any special coupling loop. One disclosed dielectric resonator device includes a first magnetic-field-coupling window for effecting magnetic field coupling between a first pair and a second pair of dielectric columns and a second magnetic-field-coupling window for effecting magnetic field coupling between a third pair of dielectric columns. Due to this construction, it is possible to successively effect magnetic field coupling between predetermined dielectric columns of adjacent dielectric resonators solely by spatial magnetic coupling, without having to employ any partition or special coupling loop. Further, this construction facilitates the provision of characteristics-adjusting holes perpendicularly to the plane made by each composite dielectric column.

    摘要: An information recording disk comprising a disk-like substrate and magnetic layers formed on both surfaces of the substrate is provided with a mark punched through the disk. The mark is provided by, for example, a hole positioned apart from a reference line passing through both the center of an index hole for specifying the circumferential position of the disk and the center of the disk. If the disk is rotated by 180.degree. about the reference line, the position of the mark is reversed with respect to the reference line, making it possible to distinguish the front and back surfaces of the disk. The magnetic layers formed on both surfaces of the substrate by means of, for example, sputtering, differ from each other in magnetic properties. To determine the magnetic layer used for the information recording-reproduction or to determine the optimum conditions for the recording-reproduction, it is necessary to distinguish the front and back surfaces of the disk. The mark provided in the disk of the present invention permits visually distinguish the front and back surfaces of the disk easily in the step of loading the disk in a package. Also, the mark can be provided in the punching step of a tape having magnetic layers formed on both surfaces thereof in a disk-like shape, thereby eliminating confusion in the later step.

    摘要: A method of manufacturing an input screen for an image intensifier which comprises the steps of thermally depositing a phosphor layer of alkaline metal halide on one side of a substrate to provide a phosphor layer formed of columnar crystals extending in a direction substantially perpendicular to the plane of the substrate; treating the surface of the phosphor layer by a liquid material of low boiling point and incapable of dissolving the phosphor, thereby producing cracks extending in a direction substantially perpendicular to the plane of the substrate in said phosphor layer; and forming a photoemissive layer on the surface of the phosphor layer, thereby enabling the phosphor layer to have a high light-guiding property and ensuring the prominent elevation of the resolving power of an image intensifier.
