    The application of reactive processing to stampable sheet of toughness improved unsaturated polyester (1993)
    Stamford, Conn. [u.a.] : Wiley-Blackwell
    Polymer Engineering and Science 33 (1993), S. 989-995 
    Details
    ISSN: 0032-3888
    Keywords: Chemistry ; Chemical Engineering
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics , Physics
    Notes: Using twin screw extrusion and stampable sheeting processes, we have investigated the application of reactive processing technology to fiber-reinforced stampable sheet made of an unsaturated polyester (UP) alloy with high toughness. As a result, we obtained a stampable sheet composed of a UP/nitrile butadiene rubber (NBR) polymer alloy matrix and glass fiber mats with physical properties equivalent to those of polypropylene (PP) stampable sheet, and moreover, with higher heat resistance than PP.

    Development of an expert system for injection molding operations (1993)
    Hoboken, NJ : Wiley-Blackwell
    Advances in Polymer Technology 12 (1993), S. 403-418 
    Details
    ISSN: 0730-6679
    Keywords: Chemistry ; Polymer and Materials Science
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: To provide a computer assisted system in finding optimum conditions for injection molding operations, an Expert System based on Artificial Intelligence (AI) technique and knowledge or “know-how” from many skilled injection molding operators has been developed. For the construction of this Expert System, we have originally applied a new method of “Multi-dimensional Matrix” that represents the relationship between the parameters of each molding condition and expert's knowledge. In this article we describe an outline of the system and the process of converting expert knowledge into AI rules, and demonstrate some molded samples obtained using this Expert System. © 1993 by John Wiley & Sons, Inc.

    The development of on-line techniques and novel processing systems for the monitoring and handling of the evolution of microstructure in nonreactive and reactive polymer systems (1995)
    Hoboken, NJ : Wiley-Blackwell
    Advances in Polymer Technology 14 (1995), S. 277-290 
    Details
    ISSN: 0730-6679
    Keywords: Chemistry ; Polymer and Materials Science

    Topics: Chemistry and Pharmacology , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: The use of newly developed polymer processing technologies to enable the microstructure control of nonreactive and reactive polymer systems, which up to now have been manufactured with conventional chemical polymerization processes, has been rapidly becoming popular, particularly in the field of polymer alloy systems. In this article the mechanisms of morphological development and its control for polymer alloys used mostly in a twin-screw extruder have been reviewed mainly from our studies. And furthermore, on-line monitoring and handling techniques developed at The Japan Steel Works are described in relation to the evolution of microstructure of polymer systems in a twin-screw extruder. © 1995 John Wiley & Sons, Inc.

    Report on the state of the art: Reactive processing using twin-screw extruders (1991)
    Hoboken, NJ : Wiley-Blackwell
    Advances in Polymer Technology 11 (1991), S. 99-108 
    Details
    ISSN: 0730-6679
    Keywords: Chemistry ; Polymer and Materials Science

    Notes: Reactive processing technology is rapidly coming into widespread use in the plastic industry as a tool for both simplifying conventional polymerization processes and creating innovative polymers and their alloys. For a long time, we have been making great efforts to develop the technology and systems related to this field. In this report, we describe fundamental functions of twin-screw extruders and introduce some applications of reactive processing using the twin-screw extruder. Furthermore, we discuss the future trends of this technology.

    Encapsulation process for electronic devices using injection molding method (1993)
    Hoboken, NJ : Wiley-Blackwell
    Advances in Polymer Technology 12 (1993), S. 61-71 
    Details
    ISSN: 0730-6679
    Keywords: Chemistry ; Polymer and Materials Science
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: In this article, a new encapsulation injection molding method for electronic devices such as integrated circuits (ICs) is described as a superior technology to the conventional transfer molding process widely used in the electronics industries. The quantitative analysis has been carried out utilizing a computer simulation program covering cavity-filling behavior to analyze the relationship between the deformation of gold wires that are bonded with mounted IC chips and mold geometries, operational conditions, and physical properties of a thermoplastic encapsulant, i.e., polyphenylene sulfide. As a result, a new technology to encapsulate ICs has been established, preventing no practical gold wire deformation or break-up damage. © 1993 John Wiley & Sons, Inc.
