Abstract:
A process for preparing phenolepoxy resin represented by the following formula: ##STR1## wherein: (a) R.sup.1, R.sup.2, R.sup.3, and R.sup.4, which can be the same or different, are hydrogen, C.sub.1 to C.sub.6 alkyl groups, C.sub.6 to C.sub.10 aromatic groups, or C.sub.1 to C.sub.6 alkyl group-substituted C.sub.6 to C.sub.10 aromatic groups; (b) R.sup.5 and R.sup.6, which can be the same or different, are hydrogen, C.sub.1 to C.sub.6 alkyl groups, C.sub.6 to C.sub.10 aromatic groups, or C.sub.1 to C.sub.6 alkyl group-substituted C.sub.6 to C.sub.10 aromatic groups; ##STR2## (c) R.sup.7 is hydrogen, C.sub.1 to C.sub.6 alkyl groups, C.sub.6 to C.sub.10 aromatic groups, or C.sub.1 to C.sub.6 alkyl group-substituted C.sub.6 to C.sub.10 aromatic groups; (d) R.sup.8 and R.sup.9, which can be the same of different, are hydrogen, C.sub.1 to C.sub.6 alkyl groups, C.sub.6 to C.sub.10 aromatic groups, or C.sub.1 to C.sub.6 alkyl group-substituted C.sub.6 to C.sub.10 aromatic groups; and (e) n is an integer of 0 or 1. The phenolepoxy resin can be advantageously used in making packaging materials for ICs, as a substrate additive for printed circuit boards, and as adhesive for the electronic industry. The process includes the steps of preparing a reaction medium which contains only polyphenol, epihalohydrinl and an imidazole catalyst, and then causing the reaction medium to react in the absence of an aqueous phase.
Abstract:
A locking device includes a body, a first part, an engaging assembly, a link and a locking member. The body has an installation area and the engaging assembly is installed in the installation area and includes a first engaging member and a first resilient member which provides a force to the first engaging member to connect the engaging member to the first part. The link is movably located in the installation area to push the first engaging member to move relative to the first part to release the locked status. The locking member is located in the installation area and has a first recess and an operation end. When the first recess is located corresponding to the first engaging member, the first engaging member is movable in the first recess. When the first recess is located away from the first engaging member, the first part is secured to the body.

Abstract:
A case assembly for electronic appliance includes a first case having a plurality of engaging members and each engaging member includes two clamping protrusions. Each clamping protrusion includes a supporting portion and a protruding portion. A space is defined between the two clamping protrusions. A second case includes multiple ports and each port has a shoulder defined in an inside thereof and the shoulder is located corresponding to the protruding portions of the clamping protrusions. Multiple positioning members each have an insertion portion and a head. A transverse width of the opening of the space is smaller than a width of the insertion portion. When the insertion portion of each of the positioning members is inserted into the space corresponding thereto, the clamping protrusions are expanded outward by the positioning member, and the protruding portions are engaged on the shoulder of the second case.
