Abstract: Disclosed is a process for the preparation of polyetherester polyols prepared with hybrid catalysts, the polyetheresters obtained from the process and the use of such materials in polyurethane applications. The hybrid catalysts used in this invention comprise double metal cyanide complex catalysts (DMC) and at least one co-catalyst.

Abstract: A molding apparatus comprises first and second mold chases that are configured to clamp an electronic device therebetween, and a driving mechanism which drives the first and second mold chases to apply a clamping force onto the electronic device. A pressure adjustment mechanism communicates with at least one of the mold chases and applies an additional clamping pressure onto one or more portions of the mold chase. The pressure adjustment mechanism comprises movable supports that are displaceable in directions which are substantially perpendicular to the direction of the clamping force so as to transmit and apply the said additional clamping pressure onto the mold chase, and also a plurality of piezoelectric actuators which are operative to apply displacement forces to the movable supports in their displacement directions.

Abstract: A capillary is provided for a wire bonding tool that comprises a holding portion for clamping the capillary, a conical portion at a tip of the capillary for performing bonding and a substantially frustoconical portion located between the holding portion and the conical portion. The sidewalls of the frustoconical portion form an interfacial angle that is smaller than an interfacial angle formed by the sidewalls of the conical portion so as to provide a gentle taper from the holding portion to the conical portion.
