Inventor: YAMATO YUUICHI
IPC: H04B3/36
Filed: 1979-10-04
Abstract: PURPOSE:To prevent degradation of the noise characteristic even if the disconnection accident of the transmission line occurs, by making the length of the coaxial line near the high group transmission-side transmission station shorter than the assumed coaxial transmission length for setting a prescribed level diagram, in respect to the submarine coaxial transmission line. CONSTITUTION:Level diagram curve 33 is distributed between high group transmission-side transmission terminal station 11 and high group receiving-side terminal station 12. In respect to inclination 33' rising near transmission terminal station 11,  the transmission level of terminal station 11 is lower than the assumed level for set  of a prescribed level diagram by -B, and meanwhile, the length of the coaxial line  near the terminal station is shorter than the assumed coaxial line for set of the prescribed level diagram, and level up portions generated by this shortening are  reduced as -B in terminal station 11. When the disconnection accident occurs at the  position of the mark X, cable patching is performed and the high group transmission level is raised by A. As a result, the rise of the level just near the terminal  station is restrained to the degree shown by solid line 41 approximately, and reduction of the overload margin is small.

Title: Freeze compression molding method
Inventor: SHIMAGUCHI TAKASHI
IPC: B22F3/02
Filed: 1986-06-04
Abstract: PURPOSE:To prevent the deformation of a molding during thawing by mixing raw material powders, water and other solvents and using molding tools for which a specific binder is used at the time of molding the powders of ceramics and metals by a freeze compression molding method. CONSTITUTION:The water and 1 or >=2 kinds among alcohol, ester and arom. solvents are added as the solvents to the powders of the ceramics and metals and the mixture is kneaded to prepare the raw material 8 for the molding. The molding material is packed between a pressurizing mold 3 and pressure receiving mold 4 consisting of a solvent collapsible material of the metallic mold 1. The mold 3 is lowered to pressurize and mold the kneaded raw material 8 for the molding and the molding 8 is frozen by a rfrigerant such as liquid nitrogen. The pressurizing mold 3, the pressure receiving mold 4 and the frozen molding 8 are then parted by ejector pins 6 from the mold 1 and are thawed. Since the two molds 3, 4 are formed by molding the powder of an inorg. or org. Material by a binder such as acrylonitrile/styrene compolymer, the molds soften by absorbing the moisture generated by the thawing of the molding 8. The shrinkage by the thawing of the molding 8 is, therefore, restrained by the molds 3, 4 and the deformation thereof is obviated.
