Title: Surface wave filter
Inventor: UMEMURA YOSHIHARU
IPC: H03H9/25
Filed: 1992-07-03
Abstract: PURPOSE:To attain a superior out-band attenuation for the surface wave filter by providing a plate-shaped projection part crossing input and output lead terminals of the surface wave filter on a bottom face of a shield case and allowing the projection part to be penetrated through a substrate together with the lead terminals. CONSTITUTION:A plate-shaped projection 5 provided on a bottom face of a shield case 1 is integrated with the shield case 1 in a form of crossing input and output lead terminals 2, 3 of the surface wave filter. Moreover, a hole 9 is made to a substrate 6 so that the plate-shaped projection 6 is penetrated on the rear side of the substrate therethrough. Through the constitution, the invasion of an undesired wave due to electromagnetic coupling between the input and output lead terminals 2, 3 of the surface wave filter is suppressed by the shield effect of the plate-shaped projection 5. Thus, a superior out-band attenuation is attained for even the surface wave filter used at a comparatively higher frequency such as a frequency for a satellite broadcast.

IPC: H04N1/411
Filed: 1990-07-04
Abstract: PURPOSE: To obtain an overall high compression ratio by assigning at least one of two kinds of compression ratios to respective adjacent data and determining it according to the frequency of information contents of data from specific adjacency on pixels in an image. CONSTITUTION: In an original frame a large low-frequency area and a small high-frequency area are discriminated, a scheme for loss compression is used for the low-frequency area and a scheme which allows no-loss compression is applied to the high-frequency area. A compressing/releasing decompression method consists of prefiltering, evaluation of compression possibility, etc. For example the prefiltering operates on a principle that pixels adjacent to a segment are removed and all black pixels are removed from a binary image, which are shown in figures 1 and 2 as an example. The figure 1 consists of a grating diffused colored dots and background noise disappears from data, after scanning, as shown in the 2nd figure. Consequently a method which compresses image data at a high compression ratio is obtained.
