Polyvinyl halide or polyvinyl graft copolymers intimately mixed with a polyester derived mainly from an halogenated bicycloheptene carboxylic acid or anhydride such as chlorendic acid or anhydride and an alkylene glycol or alkylene oxide such as ethylene oxide are provided. The graft copolymers of the invention are obtained by polymerizing a vinyl halide in bulk in contact with an olefin polymer. The graft copolymer compositions of the invention have good clarity and provide improved processing characteristics and increased impact strength without reduction in heat distortion resulting from the addition of the polyester. The improved impact strength polyvinyl halide compositions of the invention can include blends of the polyester of the invention with modifying compounds, such as alkyl methacrylate-butadiene/styrene graft polymer impact modifiers and halogenated polyvinyl chloride. Blends of vinyl halide polymers with the polyesters of the invention provide compositions having improved processability. A reduction in melt viscosity and fusion temperature can be obtained in the blends while maintaining or increasing heat distortion temperature. The compositions of the invention are useful in the production of molds made by extrusion, injection, blow, and sheet molding processes.

Urethane elastomers are prepared by reacting a long-chain polyol having a molecular weight of 400 - 5000 in a one-shot operation with an organic diisocyanate and a halogenated aromatic diamine of the general formula: ##STR1## wherein X.sub.1, X.sub.2, X.sub.3 and X.sub.4 are the same or different and each represents a halogen atom and n is zero or 1. According to this process, urethane elastomers possessing excellent physical characteristics can be produced economically and advantageously in the operations.

A semiconductor electrostatic device for producing an output electrostatic force includes an active element, an opposed field element and a control element. The active element has a semiconductor region containing carriers movable in response to an applied electrostatic field only when the field exceeds a predetermined threshold level. The field element generates the electrostatic field and applies the field to the semiconductor region of the active element. A control element controls the electrostatic field to selectively exceed the threshold level so as to localize the carriers within the semiconductor region to thereby generate an output electrostatic force. The device may be configured to output a useful electrostatic force exceeding the inverse of the squared value of the distance between the active element and the field element. Either the active element or the field element of the semiconductor electrostatic device may be configured to be movable in response to the output electrostatic force and the movable element may be used in many applications requiring a movable element, including a mechanical switch, a valve, an electric switch, or a shutter for an optical device. The electrostatic force may be alternatively be used to attract and fix or test a workpiece. In this configuration, the semiconductor electrostatic device may be used for handling or for testing a workpiece, such as a semiconductor wafer.

A windshield support is formed as a cantilever-like or overhang support including a bend portion 16, a box portion and a flange portion 20 which are formed continuously in that order. The bend portion 16 is extended from an instrument panel upper portion 12 and has a substantially V-shaped cross section. The box portion 18 has a hollow rectangular cross section and is sufficiently disposed away from the instrument panel upper portion 12. The flange portion 20 receives a front window glass 15. A recessed portion 12a is provided at the instrument panel upper portion 12 for receiving a lower portion 18a of the box portion 18 when the bend portion 16 has to be bent by virtue of an external force applied to the windshield.
