摘要： PROBLEM TO BE SOLVED: To provide a method for controlling kneading of a polymer material kneader having small unevenness of material quality. SOLUTION: In the case of masticating or kneading a solid polymer material by using a seal type kneader (Banbury mixer) 12 having rotors 16, rotor power (rotary power of rotors 16) and polymer material temperature in the kneader 12 are sensed. Instantaneous values of the rotary power and the material temperature are input at a predetermined period to a viscosity prediction formula with two variable functions with first and second variables of the rotary power and the material temperature, and compared with preset viscosity reference value. And, the kneading is finished based on the presence or absence of arrival, of the value at the reference value.

摘要： PURPOSE:To prevent generation of a deformation of an insert at the time of casting of a material and collapse of a form or distortion of the insert at the time of mold release, by a method wherein the insert is kept at a temperature where the insert possesses a shape retention capacity at the time of the casting of a rubber material and pulling out of a core. CONSTITUTION:An inner circumferential surface 31 is formed of a hard resin ring part 7 and a rubber body part 9 is composed of a rubber compound and a cut part 6 is formed on the same in a stabilizer bushing 31. A ring part 7 which becomes an insert is formed through extrusion or injection and held by inserting a core 19 into same. The ring part 7 is set to a bottom force 21a of a mold 21 and the rubber compound is cast into a cavity 23 by performing mold clamping. Although the temperature of the rubber compound is close to the softening temperature of a forming material of the ring part 7, since a casting period of time is short, deformation of the ring part 7 does not happen. At the time of heating and vulcanization of the mold 21, a temperature rise of the ring part 7 is performed also and the ring part 7 adheres to the rubber compound. When the ring part 7 is cooled down to a temperature where the ring part 7 possesses the shape retention capacity, the core 19 is pulled out.

摘要： PURPOSE:To enlarge the frequency range capable of preventing the vibration and noise by forming at least one of spring-constant variable layers, which is constituted of an elastomer having a particular glass transmission point and a heating member disposed on the surface of the elastomer or inside thereof. CONSTITUTION:An elastic member 4 is disposed between an upper holding plate 2 and a lower holding plate 3. The elastic member 4 is constituted of fixed layers 5, of which principal ingredient is crude rubber, and spring-constant variable layers 6, which is made of polynorbornane with the glass transmission point ranging from 10 deg.C-50 deg.C and contains thread-like heating elements 7 therein, and then, direct current is applied from a power source 9 through a lead 8. Thereby, in the unenergized state, the elastic member 4 possesses an inherent spring constant, which is the composition of those of the spring-constant variable layers 6 and the fixed layers 5, so as not to resonate with the vibration due to an engine during the ordinary rotation, while at the time of energizing, the elastic member 4 possesses such a spring constant as not to resonate with the vibration due to the engine during the high speed rotation. Therefore, it is possible to enlarge the frequency range capable of preventing the vibration and noise.
