Title: Coiled rubber tube, manufacture thereof and mandrel for manufacturing coiled rubber tube
Inventor: SAKAINO SUSUMU
IPC: B29C69/02
Filed: 1988-03-11
Abstract: PURPOSE:To obtain a compact coiled rubber tube, the strain of which is slight, by a method wherein the coiled rubber tube is primarily vulcanized under the state of being coiled in normal helix and, after that, secondarily vulcanized under the state of being coiled in reverse helix and finally rewound in normal helix. CONSTITUTION:A watersoluble coagulating agent film is formed on the surface of a coarse- pitched coiled mandrel over the domain ranging from the tip straight part 13a to the rear end straight part 13b of the mandrel. A rubber layer 2 is formed by immersing the mandrel in a latex tank. When the latex is natural rubber, for example, the rubber layer is primarily vulcanized by being heated at 80-100 deg.C for 3-5hr. As a result, a rubber tube 2 hardens to some extent and can be demounted from the mandrel 1 for handling and the pitch of the demounted tube results to be smaller than that of the mandrel by about 5%. Concretely, water is passed under pressure through the rubber tube 2 so as to wash off a part of the coagulating agent in order to draw the rubber layer 2 out of the mandrel 1 by turning it. The rubber tube 2 is rewound in reverse helix, immersed in hot water having a temperature of about 60 deg.C for about 2 days in order to remove the remaining coagulating agent and, after that, dried so as to be secondarily vulcanized by heating at 80-100 deg.C for 3-5hr. Finally, by rewinding the rubber tube again in normal helix, a fine-pitched coiled rubber tube is obtained.

Abstract: PURPOSE:To obtain compact structure and freely variable damping force by moving a movable substance in a cylinder against a belleville spring in order to vary the specific gravity of the magnetic fluid by means of electric current in an electromagnetic coil together with guiding magnetic fluid to flow through an orifice. CONSTITUTION:A cylinder 1 in the form of a short tube is connected to a supporting structure side, while a movable substance 2 that is nearly in a cylindrical form is connected to a supported structure side. When downward load is imposed on the movable substance 2, the load is elastically supported by resilient force of belleville springs 10 and 11 which are locked to the inside surface of the cylinder 1 at both upper and lower parts of a coil case 3. When the movable substance 2 is moved up and down by outside exciting vibration, volume ratio between two, or upper and lower, magnetic fluid chambers 5 and 6 varies corresponding to the position of the movable substance 2. And magnetic fluid the flow rate of which is proportional to the variation in the said ratio flows, passing an orifice 7 or 8 that is formed between the movable substance 2 and the coil case 3, thereby producing damping force. By varying amperage in an electromagnetic coil 4, apparent specific gravity of the magnetic fluid passing the orifice can be changed so that the damping force can be changed at will.

Abstract: PROBLEM TO BE SOLVED: To adjust a sound volume level corresponding to a surrounding state changing time by time automatically by deciding a minimum mean value among plural mean values of amplitude levels of received voice signals and selecting the decided minimum mean value to be a noise sound level. SOLUTION: The equipment is made up of an amplitude detection circuit 22 detecting an amplitude level of a voice signal, an adder 24 calculating a mean value of the amplitude levels for each prescribed time, and a 1st register 25 deciding a minimum mean value among plural mean values. Then the amplitude level of the voice signal picked up by a transmission microphone is detected and the mean values of the detected amplitude levels with respect to a range of the prescribed times are calculated, and the minimum mean value among the calculated mean values is used for a noise sound level. Since the noise sound level is calculated based on the voice signals picked up by the transmission microphone in this way, the noise level is calculated without new provision of a device for noise sound level measurement.
