Abstract: ABSTRACT:     Socket for receiving edge of a chip carrier substrate comprises a dielectric housing having an elongate channel interrupted by partitions having aligned U-slots which limit position of substrate. Cavities separated by the partitions receive U-shaped contacts each having a base with directly opposed arms formed upward therefrom and a flat pin formed downward therefrom and extending into respective apertures in the floor of the channel. Arms present convex rolled inside surfaces to opposed surfaces of substrate for electrical contact therewith. Floor of channel has convex portion in each cavity on which base rocks as pin deflects resiliently in chamfered lead-in to aperture to accommodate any substrate warpage.          Profile of U-slot in partition prevents stressing of arms beyond elastic limit. One embodiment of contact comprises a pair of opposed arms formed upward to a bend where each is formed through an obtuse angle toward the other arm of the pair, one arm being stamped from a continuous carrier strip leaving an aperture, each contact being attached to the carrier by a pair of straps .

Abstract: ABSTRACT OF THE DISCLOSURE         In manufacturing a  DC motor body  including a  motor  magnet,  conventionally,  a  magnetized  magnet is fitted to one by one to    the cylindrical molding core  and  a motor  body  is injection-molded  within  a cavity formed between a motor body forming mold and a cylindrical molding core to which the magnet is at-tached.  Therefore,  the magnet  should  previously  be molded and stocked before molding the motor body, thus being  not  applicable  to  mass-production  processes. To overcome the above problems,  the motor magnet and the motor body are molded  in  sequence  in accordance with two separate molding steps by the use of the same molding  core.  This  method  can  eliminate  troublesome magnetic  fitting work,  the  need of magnet  stock and enhance  the  dimensional  precision  of  motor  magnet, thus being applicable to mass-production process while increasing  the  energy  transduction  efficiency of  the DC motor.

Abstract: ABSTRACT:          ''Method of, and device for, decoding a repeatedly address-able information stream which is protected by a  symbol-correction code''.           During the decoding of a code word of an infor-mation stream which is protected by a symbol-correction code, first all channel symbols are demodulated; a first in-dicator flag then indicates whether or not the demodula-tion is reliable. All code symbols of a code word are subsequently collected, after which the decoding operation commences; the code word is corrected if possible and neces-sary. The reliability of the correction is indicated by a second indicator flag. When the correction is unreliable, the stream of channel symbols is addressed again. During the latter operation only unreliably decoded code sym-bols are replaced by new code symbols in order to enable renewed decoding of the code word thus modified.

Abstract: ABSTRACT OF THE DISCLOSURE         A system for performing talk and data transmission by a polling process between terminal units and a central station, which system is capable of interruption talk during data transmis-sion, is described.  The central station is provided with slots for use in interruption given at appropriate time intervals in the polling process.  Thus the central station is given, as one of its functions, the function of until the predetermined polling is finished, repeating steps of (i) generating interruption accept-ance signals at appropriate intervals in the polling mode, (ii) giving thereafter a plurality of time slots for receiving the interruption signals from the terminal units, and (iii) when inter-ruption signals from the terminal units are received in the plural-ity of time slots, returning to the talk mode by generating a polling finish signal and terminating the polling or simply ter-minating the polling, and when not received, continuing the polling.  The terminal units are given, as one of their functions, the function of when occasion demands to do talk in the polling mode, either manually or automatically, assuming a plurality of slots timed with the central station, independently after receiving the interrupt acceptance signal from the central station, electing at random one of the slots and sending an interruption signal through such slots.  Thus the talk and the data transmission by the polling process are realized in the same channel.

Abstract: ABSTRACT OF THE DISCLOSURE A cable meter for monitoring the channel selected by a converter of a television system which receives signals by means of cable.  The cable is connected to the cable meter and the output of the cable meter is applied to the converter.  The output of the converter is connected back to the cable meter which, in turn, provides an output to the television.  During normal operation, signals received by the cable meter from the cable pass directly to the converter, and a selected channel from the converter passes through the cable meter to the television.  To monitor the channel selected, an oscillator generates a substitution signal which is substituted for the television signal applied to the converter.  The cable meter then monitors whether the sub-stitution signal passes through the converter, during which period, the cable meter prohibits this substitution signal from reaching the television.  By varying the frequency of the substitution signal, a search is performed for the selected channel.  Techniques are employed to enhance the accuracy of the monitoring.  The present invention has applicability to any communications system in which radio frequency signals are transmitted over any medium, such as televisions with internal tuners which may not even be adapted to receive cable signals or radio receivers.
