    摘要： The device characteristics is in containing a maleimide resin with a content of 0.2 weight percent of less of an organic acid, a phenolic resin, and a combination of a basic catalyst and a peroxide as a curing catalyst. In addition, additives as a mold release agent such as a polyethylene wax and an inorganic filler are contained. The maleimide resin composition is prepared in such a manner that a part of the phenolic resin is preblended with the curing catalyst in advance of other components, while the remainder of the phenolic resin is added to the maleimide resin to prepolymerize, and then, the preblend and the prepolyer are blended the other components. The maleimide resin composition has excellent moldability by improvement of curing characteristics through combined use of a basic catalyst and a peroxide as a curing agent. Besides, a resin encapsulated semiconductor device manufactured by encapsulating a semiconductor element with the resin composition has excellent heat resistance and moisture-resistance reliability.

    摘要翻译： 该装置的特征在于含有0.2重量％以下的有机酸，酚醛树脂，碱性催化剂和过氧化物的组合的马来酰亚胺树脂作为固化催化剂。 此外，含有作为脱模剂的添加剂如聚乙烯蜡和无机填料。 马来酰亚胺树脂组合物的制备方法是将一部分酚醛树脂与其它组分预先与固化催化剂预混合，同时将剩余的酚醛树脂加入到马来酰亚胺树脂中进行预聚合，然后将预混物 并将预分散器与其它组分混合。 马来酰亚胺树脂组合物通过组合使用碱性催化剂和作为固化剂的过氧化物来改善固化特性，具有优异的成型性。 此外，通过用树脂组合物封装半导体元件制造的树脂封装的半导体器件具有优异的耐热性和耐湿可靠性。

    摘要： The detergent of this invention, directed to the cleaning of an object having a gap portion at least in part thereof, contains at least one of components of the detergent having a solubility parameter difference of not more than 3 from and a contact angle within 15.degree. with at least one of components of a smear on the object. The detergent provides an ideal cleaning for the object because it easily permeates into and dissolves the machining oil filling the gaps between closely cohering thin metallic strips. The method of cleaning according to the invention has first cleaning the object with a polar detergent and then rinsing and drying the cleaned object with a detergent having low polarity or no polarity. In the precision cleaning of such objects as electronic parts, therefore, it manifests satisfactory cleaning and drying properties. The detergent and the method of cleaning mentioned above are both safe in the environment because they have no use for such detergents as the Flon type and the chlorine type solvents which induce the destruction and the pollution of the environment.
