Abstract: A fluid transmitting device includes aside cover connected to a pump impeller and defining a clutch chamber between the side cover and an outer surface of a turbine runner, and a lock-up clutch which includes a clutch piston connected to the turbine runner. The clutch chamber is divided by the clutch piston into an inner oil chamber and an outer oil chamber. In the fluid transmitting device, a dividing means for dividing the inner oil chamber into a primary inner oil chamber section and a secondary inner oil chamber section is provided between the turbine runner and the clutch piston. When a lock-up control device is operated to urge the clutch piston in a clutch switch-on direction, the pressures in the primary inner oil chamber section and the secondary inner oil chamber section are raised in the named order relative to the outer oil chamber. Thus, the connection responsiveness of the lock-up clutch can be enhanced in a simple structure.

Abstract: Copolycondensation of .alpha.-naphthol and .beta.-naphthol with an aldehyde compound gives a poly-hydroxynaphthalene compound having an average molecular weight of 300 to 2,000. This compound is useful as a curing agent for epoxy resins and as a precursor of epoxy resins. Epoxy resin compositions include (1) compositions comprising an epoxy resin and the poly-hydroxynaphthalene compound as a curing agent and (2) compositions comprising an epoxy resin obtained by reacting the poly-hydroxynaphthalene compound with an epihalohydrin and a curing agent. The epoxy resin compositions of the invention are characterized in that the cured resins have a high glass transition temperature and high heat stability and high moisture resistance, scarcely allowing package cracking even in soldering treatment. Therefore the compositions are suited for use in encapsulating semiconductors.
