Title: Facsimile transmission controller
Inventor: NARUKAMA KAZUO
IPC: H04L29/06
Filed: 1985-05-02
Abstract: PURPOSE:To prevent deteriorated communication by bringing the mode to the low-order mode when training check is not established in the G3 mode. CONSTITUTION:When a training check discrimination section discriminates it that an FTT repeats the transmission of a prescribed number of times and the training check is not established, a mode changeover section 4 transfers the mode to the low-order mode of the G2 or the G1 (in this case, a G1 transmission control section is required) by a G2 transmission control section 2 in place of the output of a cut-off instruction DCN. When an outgoing station receives the 3rd FTT, the G2 transmission control section 2 sends continuously a GC (group command) signal, and LCS (line conditioning signal) and a PHS (phase signal) sequentially. When the phase matching by the PHS is finished, a CFR2 (reception acknowledgement signal) is returned to the outgoing station. The outgoing station receiving the said signal uses the G2 transmission control section to send the picture signal by the G2 mode.

Abstract: PURPOSE:To heighten the degree of foaming by feeding an extruder with a resin mixture prepared by adding a foaming nucleus agent to a fluorinated resin, putting a foaming gas by pressure into the extruder, and performing an electron beam irradiation bridging process. CONSTITUTION:A resin mixture prepared by adding a foaming nucleus agent to a fluoric resin is cast into a cylinder of an extruder, and also a foaming gas is put into the cylinder. Resin as the fluorinated resin described should preferably be ethylene tetrafluoroethylene copolymer (ETFE). Ordinary example of the nucleus agent for foaming is boron nitride, while the foaming gas is usually fron-22 or N2. From a die discharge hole of an extruder, the mentioned resin mixture is extruded to be put as covering on a conductor, and also an electron beam is cast onto this resin compound covering the conductor, and an electron beam irradiation bridging takes place. This enhances the melting viscosity of the resin mixture, and a covered electric wire having a higher degree of foaming than conventional is obtained.
