    摘要： In the present invention, miniaturization of an electric power conversion system is made possible while the reduction of a rise in temperature is achieved through a cooling operation by a cooling fan. The electric power conversion system is provided with a casing for covering cooling fins for cooling power semiconductors, a main circuit board having a driver circuit for driving the power semiconductors, and a cover for covering up the main circuit board. The system includes a first airflow hole provided at a part of the main circuit board, on the upper side of an air-intake provided in the cover, and a second airflow hole provided on the lower side of the first airflow hole, and on the lower side of the cooling fins, wherein air from the second airflow hole is driven to the cooling fins by a cooling fan.

    摘要： An in-mold decorated molded article wherein a coating layer is formed on a top surface of a transparent molded resin body which is flattened in a thickness direction of the body, thereby covering an edge part of the top surface adjacent to a side face on with a side gate mark formed, in order for the side gate mark not to be seen from the top surface of the molded resin body, and a decorative layer is formed on a bottom surface of a decorative layer of the transparent molded resin body. According to an in-mold decorated molded article, even when the transparent molding resin is employed with the result that an agreeable appearance is not achieved despite of a treatment for the side gate mark, the design property of the in-mold decorated molded article can be maintained, the gate mark of unacceptable appearance being not seen from the top surface.

    摘要翻译： 一种模内装饰成型制品，其中在透明模制树脂体的顶表面上形成涂层，该透明​​模塑树脂体在主体的厚度方向上被压平，从而覆盖与侧面相邻的顶表面的边缘部分， 形成侧门标记，以便从模制树脂体的顶表面看不到侧栅标记，并且在透明模制树脂体的装饰层的底表面上形成装饰层。 根据模内装饰成型品，即使使用了透明模塑树脂，结果即使对侧浇口标记进行了处理也没有达到令人满意的外观，因此模内装饰成型品的设计性能可以 要保持，从顶面看不到不可接受的外观的门标。
