Abstract: A process for purifying maleic anhydride graft polyolefin comprises adding an aqueous solution of alkali metal hydroxide to a solution of maleic anhydride graft polyolefin containing unreacted maleic anhydride and dissolved in an organic solvent at a temperature from 80°C to 160°C, thereby precipitating maleic anhydride graft polyolefin particles to make a W/O emulsion; stirring the W/O emulsion while maintaining the temperature within the above temperature range for less than 2 hours; adding further aqueous solution of alkali metal hydroxide to the W/0 emulsion to change it into an 0/W emulsion; and separating and washing the maleic anhydride graft polyolefin particles with water.An organic solvent having no affinity for water and with a boiling point not lower than 80°C can be used, which simplifies the recovery of the solvent; moreover unreacted maleic anhydride is changed into water-soluble maleic anhydride salt, but grafted maleic anhydride groups in the modified polyolefin can be prevented from changing into alkali metal salt, by using a solution of inexpensive alkali metal hydroxide in a specific concentration, which provides maleic anhydride graft polyolefin with good adhesion.

Abstract: An AMI signals receiver generates a logic signal stream representative of AMI encoded information signals which have traversed a transmission medium. Adaptive compensation circuits are responsive to characteristics of the received AMI signals for generating a bipolar signal ideally corresponding to the transmitted AMI signal but in practice includes noise primarily caused by near-end crosstalk. An apparent improvement in the signal-to-noise ratio is achieved by generating a unipolar signal from instant and last amplitude samples of the bipolarsignal and thereafter differentially decoding a binarysignal representation of the unipolarsignal.

Abstract: An electro-optical apparatus transforms a single stabilized frequency, linearly polarized laser input beam (18) from a light source (10) into an output beam (46) having two orthogonal polarization components of different frequency. The input beam (18) is provided to an acousto-optic Bragg cell (20) which is driven by the output of an electrical oscillator (30) which provides the Bragg cell (20) with a frequency stabilized electrical signal (32) comprised of two different frequencies.

Abstract: Automated positioning appartus for positioning multi-contact components (from 15) on a circuit (on 17) utilizes automated members having a high degree of repetitive movement but not in themselves accurate, such member realtively inexpensive. A positioning member (11) picks up a component and moves it over a first viewing head (18). The component is viewed and its orientation determined. A viewing head (14) on the positioning member (11) is then positioned over a target on a circuit board and its position and orientation determined. The results enable the positioning member to position the component on the circuit board in the correct position and orientation. The viewing heads (14, 18) are calibrated for aspect ratio and pixel dimension. Also, the fields of view of the viewing heads are calibrated for orientation relative to the positioning member (11). The position and orientation of the viewing head on the positioning member relative to a pick-up member on the positioning member is also obtained.

Abstract: The circuit for converting an analog signal into corresponding N-bit digital signal (A/D converter ) of a parallel comparison type comprises a 2 N-M  number of M-bit encoders(6),a single N-bit encoder(8)and error suppression circuits(10),a block indicating signal on a block indicating line belonging to each M-bit encoder serving as an output inhibit signal for one of the other error suppression circuits connected to the M-bit encoder in one lower order (or higher order) with respect to the corresponding M-bit encoder, and the block indicating line of each M-bit encoder being connected to an output terminal of one of the comparators in a lowest order (or highest order) or a few comparators in the comparator group to which the corresponding M-bit encoder is connected. Therefore, if an output signal is generated from the highest comparator (or lowest comparator) in the comparator group whose output terminals are connected to the corresponding M-bit encoder, the transmission of the output signal of the M-bit encoder in one lower order (or higher order) to the N-bit encoder is interrupted by means of the corresponding error suppression circuits when the output signal from the one lower order (or higher order) is generated. The block indicating signal is directly used as the output inhibit signal for the one lower order error suppression signal so that no particular gate circuit is needed, thus reducing the number of transistors. In addition, a small number of comparators are connected to the block indicating line so that the number of transistors is accordingly reduced.
