Title: Fuel hose and its manufacture
Inventor: MURAKAMI KOYO
IPC: F16L11/10
Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To manufacture a hose with ease and at a low cost, by laminating, heat treating and integrally forming a polyamide resin inner layer on the inner circumferential surface of an acrylonitrile-butadiene rubber outer layer without an adhesive. SOLUTION: In the manufacture of a fuel hose, a rubber composition is prepared by mixing a rubber material for forming a rubber outer layer, carboxyl containing NBR, a divalent to tetravalent metallic compound, a vulcanizing agent, a vulcanization accelerator and a plasticizer, and a tubular rubber outer layer is formed by being injection molded or being vulcanized after molding. Next, polyamide resin powder is charged and stuck on the inner circumferential surface of the outer layer so as to electrostatically coat the inner circumferential surface of the outer layer, however, a powder fluidizing/clipping/coating method and a spray atomizing method can be used. Then, heat treatment that polyamide resin powder and the rubber outer layer are integrated, is executed under a condition of a temperature of 200 to 220 deg.C and time of 10 to 30 minutes.  By this treatment, it is considered that NBR activated by the divalent to tetravalent compound and fused polyamide are bonded each other. Therefore, a complex-shaped hose can be manufactured without increasing a cost to a large extent and deteriorating environment.

Filed: 1988-09-13
Abstract: PURPOSE:To immediately conclude a moving object as an illegal invader when a warning is issued against the object by modulating the phase of radio waves by of a specific code when the radio waves are issued to a moving object to which no warning is required from an invasion watching device. CONSTITUTION:When radio waves from an antenna 30 reach a moving object 71 fitted with a responder 80, the radio waves are reflected by the object 71 after receiving a Doppler frequency shift and, at the same time, radio waves which are modulated by means of a specific code from the responder 80 are reflected. While the Doppler-frequency shifting frequency to an ordinary moving object 70 is low, the frequency of the specific code can be made appropriately higher. Therefore, characteristics of a low-pass filter (LPE) 50 and band-pass filter (BPF) 51 are set so that the Doppler-frequency shifting frequency and frequency of the specific code can respectively pass through the LPF 50 and BPF 51 only. Then, when the radio waves of the antenna 30 reach the moving object 71, the LPF 50 and BPF 51 simultaneously output and a controller 90 controls a warning device 60 so that the device 60 cannot be actuated when reflected waves match the specific code.
