摘要:
A thermoplastic composition is provided which comprises a phenylene ether resin, a preformed, two-phase rubber modified, high impact vinyl aromatic resin, and a preformed styrenic homopolymer which has a number average molecular weight of 65,000 to 120,000.
摘要:
A lamp and lamp driver are disclosed, in which single intensity marker lamps that are desired to be flashed can be connected to a lamp driver employing an exclusive OR (XOR) logic circuit. In one application, this lamp driver is coupled to a vehicle turn function wire and marker function wire, and a plurality of marker lamps in a row can be of the same style, but one lamp can be flashed in the row of marker lamps. In some embodiments, if all of the marker lamps are on, the lamp being driven by the XOR driver circuit will flash out of sequence with the turn signal flash. If all of the marker lamps are off, the lamp being driven by the XOR driver circuit will flash in sequence with the turn signal flash. Other embodiments are disclosed.
摘要:
Noise suppression system for a relay-switched windshield wiper, wherein reversal of current to a motor driving the wiper causes the motor to reverse. Filters contained within the motor, together with filters and shielding located external to the motor, suppress rf emissions.
摘要:
The invention provides thermoplastic blends of a polyphenylene ether, a polystyrene, a substantially hydrogenated styrene-butadiene block copolymer, and a rubbery acrylate polymer; said blends may have improved thermal stability, gloss, color, and processability, heat distortion, and impact strength.
