    摘要： There is provided a flat type piezoelectric ultrasonic motor for generating a rotation force to a rotor by ultrasonic vibrations. In the piezoelectric ultrasonic motor, a vibrator is formed of elastic material at a given size, a plurality of piezoelectric plates are attached on the vibrator, a rotor is drivingly connected to the vibrator thereby to be rotated, and a power source unit applies driving voltages to the piezoelectric plates. The piezoelectric plates are arranged on quartered surface areas of the vibrator in such a way that longitudinal axes of neighboring piezoelectric plates form a given angle therebetween and opposing piezoelectric plates have opposite polarizations, and the power source unit applies alternating driving voltages to the piezoelectric plates thereby to make the rotor rotated, thereby making it possible to simplify the piezoelectric plates' shape, minimize its size and enhance its driving efficiency.

    摘要： Disclosed herein is an impact modifier for a polymer composition and a method of preparing the same. The impact modifier includes a core comprising a polyorganosiloxane, an acrylate polymer and a styrenic polymer; and a shell generally surrounding the core, the shell comprising a polymer attached to the core. The method includes providing a silicone rubber particle; adding a polymerizable styrenic compound into the silicone rubber particle; polymerizing the polymerizable styrenic compound within the particle to provide a styrenic polymer; adding a polymerizable acrylic compound into the silicone rubber particle; polymerizing the polymerizable acrylic compound within the silicone rubber particle to provide an acrylate polymer; and grafting a polymerizable compound onto the silicone rubber particle to provide a shell substantially surrounding the silicone rubber particle comprising the styrenic polymer and the acrylate polymer.

    摘要： A polycarbonate composition and its use as a molded article and as housing or a part of electronic device are disclosed. The polycarbonate composition includes a polycarbonate resin, a liquid crystalline polymer resin, a core-shell grafted copolymer and a low molecular weight polyolefin. The composition has an impact strength of at least about 68 kg·cm/cm when a specimen of the composition is subject to a chemical treatment and the chemically treated specimen is tested according to the standard ASTM D256 (⅛″ notched). The composition has an impact resistance of exhibiting substantially no cracking when a specimen of the composition is subject to a chemical treatment and the chemically treated specimen is tested at 0.6 m according to the standard ASTM D3029. The chemical treatment includes submerging the specimen in paint thinner for 20 seconds and thereafter drying the specimen at 70° C. for 5 minutes. Further, the composition has a fatigue resistance of at least about 130,000 when a specimen of the composition is tested at 4000 psi at 5 times per second according to the standard ASTM D638.
