摘要： PURPOSE:To enable assurance of dimensional precision during the year by calculating an optimum takeout temp. wherein a specified value being an optimum temp. difference for a year is added to the mean value of the atmospheric temp. per day and calculating a cooling time of the inside of a mold necessary to obtain this takeout temp. from a cooling curve which resin material has. CONSTITUTION:The atmospheric temp. To and the surface temp. Tr of a molded form at a time of takeout are measured by the use of a thermocouple. This measured value is stored in a CPU as data. In order to prevent the linear fluctuation in the amount of thermal shrinkage accompanying the fluctuation during the year of the atmospheric temp. To, the optimum temp. difference DELTAT for a year described hereunder may be always held at a specified value: DELTAT=Tr-To. Therefore the temp. Tr of the molded form at a time of takeout is controlled by a formula 1 in correlation with To. Tr is controlled by the cooling time gamma of the inside of a mold. The atmospheric temp. To is always measured but the temp. utilized for control in the mean value To per day obtained from the value measured in the previous day. The temp. Tr of the molded form for To at a time of optimum takeout is calculated from the formula 1. Furthermore the optimum cooling period gamma is calculated from Tr by a formula 2 and control is performed.

摘要： PURPOSE:To obtain the title resin excelling in elongation and tensile strength and improved in impact resistance and abrasion resistance, by adding an additive based on a fluororubber to a liquid crystal polyester resin. CONSTITUTION:The title resin is prepared by adding an additive based on a fluororubber and, optionally, a filler (B) such as carbon fiber, glass fiber or talc to a liquid crystal polyester resin (A). This resin is an injection-moldable resin material used for, e.g., coating the surface of a rotor of an automobile supercharger. By adding a specified amount of additive B to resin A, the title resin increased in elongation and tensile strength and excelling in impact resistance and abrasion resistance can be obtained. In said rotor, scoring or the like occurs very rarely though they occur in a conventional rotor frequently because of rubbing due to an error of assembly, thermal expansion, vibration, etc.

摘要： PURPOSE:To obtain the title resin having excellent flexibility and improved elongation, tensile strength, impact resistance and abrasion resistance, by mixing an olefin elastomer with a mixture of a liquid crystal polyester resin with a Teflon resin. CONSTITUTION:The title resin is prepared by mixing an olefin elastomer (C) with a mixture of a liquid polyester resin (A) with a Teflon resin (B). This resin is an injection-moldable resin material used for, e.g., coating the surface of a rotor of an automobile supercharger, and is one excellent in flexibility and improved in elongation, tensile strength, impact resistance and abrasion resistance. By adding elastomer C to a material formed by mixing resin A with resin B, the title resin decreased in hardness without increasing a resin B content, free from a problem of lowered blendability and improved in low- temperature adhesiveness can be obtained.

摘要： PURPOSE:To obtain the heating cylinder of a molding machine having radiation and heat transfer functions by arranging a band heater to the outer circumferential face of the heating cylinder main body made of steel and providing a ceramics layer for radiating far infrared rays to the inner circumferential face of the heating cylinder and fitting a reinforcing liner to the inner circumferential face of the ceramics layer. CONSTITUTION:In a heating cylinder M, a ceramics layer made of SiO2 for radiating far infrared rays is fitted to the heating cylinder main body 1 made of chrome-molybdenum steel. Furthermore a reinforcing liner 3 is fitted to the inner circumferential face of the ceramics layer 2. The SiO2 ceramics layer 2 is heated by heat transfer from a band heater 4 fitted to the outer circumferential face of the cylinder main body 1 and far infrared rays are irradiated. Therein the wavelength absorption characteristics of plasticized substance being an organic substance are allowed to coincide with the wavelength of far infrared rays and the wavelength of far infrared rays is 3 - 400 mum. For example, absorption of infrared rays of vinyl chloride and PP is effective in a range within 3 - 25 mum. Therefore since the plasticized substance 5 in the inner circumferential face of the heating cylinder M absorbs radiation heat of the far infrared rays radiated from the SiO2-based ceramics layer 2, the surface and the inside of the plasticized substance can be simultaneously heated.

摘要： PURPOSE:To prevent exfoliation of a resin layer by covering an insert member made of aluminium alloy with a resin layer made of the liquid crystal polyester resin or the composition thereof through injection molding. CONSTITUTION:The surface of an insert member 6 which is made of aluminium alloy and has a cocoon-shaped outer shape is covered with the resin composition consisting of liquid crystal aromatic polyester resin, graphite, fluorinated resin through injection molding. Since, with such constitution, the volume contraction rate in the coagulation from molten state of the resin composition is small and the difference of the thermal expansion rate from aluminium alloy is small and the resin composition intrudes into the uneven part on the surface of the insert member 6, a Roots type pump rotor 1 in which the resin layer is not exfoliated even after the use for a long period can be obtained.
