Title: Branch filter/synthesizer
Inventor: TAKAHASHI KUNIHARU
IPC: H01P1/213
Filed: 1997-01-08
Abstract: PROBLEM TO BE SOLVED: To reduce an attachment area, to prevent degradation of high frequency attenuation caused by the input/output coupling in a filter and the degradation of isolation between transmission and reception and to reduce costs by inputting a signal while branching it to respective strip line resonators. SOLUTION: The signal from an input terminal 13 is outputted from an output terminal 15 to the outside through a transmission line 11f and a strip line resonator 11. Around a ground conductor layer 3c and at its central part, plural through holes 14 are provided similarly to a ground conductor layer 3a. However, a through hole 5 forming the input terminal part 13 is provided with an insulating part 42 so as to be electrically insulated from the ground conductor layer 3c. Thus, plural strip line resonators 11 and 12 can be mounted in the area for one strip line resonator 11. Besides, since the strip line resonators 11 and 12 are almost completely electrically shielded by upper and lower ground conductor layers 3a, 3c and 3e, the degradation of isolation can be prevented.

IPC: C22B1/16
Filed: 1989-01-09
Abstract: PURPOSE:To pelletize the material into rigid manipelletes by charging ore having the description of the deterioration in pelletizing properties in which fine powder ore and water are blended into a compacting and plasticizing space, subjecting the ore to compaction kneading to bring it into a flaky shape under a prescribed vibrational force and furthermore subjecting it to rolling agglomeration under the same force. CONSTITUTION:A compacted medium is mixed to the ore such as Carol ore and fine iron ore and the compacted medium is provided with circular motion under >=3kg exciting force [(g) denotes the acceleration of gravity]. In this way, the compacted medium is rotated in the direction of the same rotation to cause the relative backward motion of the surfaces between the adjacent compacted media. Then, the sintering material grains present between the adjacent compacted media are subjected to the joining operation such as compacting, shearing, rolling, squeezing, mulling and kneading. As the result, the group of the grains enters into a capillary area, which are formed into flakes having high bonding strength and are plasticized. Then, the flaky material itself is subjected to rolling by high exciting of >=3g exciting force. As the result, the increase of packing density, the penetration of moisture into the surface, the adhesion by the moisture and the growth of grain size occur, by which minipellets having high strength can be obtd.
