Abstract: Electrically conductive compositions are provided. The compositions contain a nonconducting polymeric component and an electrically conducting polymeric component. The electrically conducting component is conducting because it is protonated. These compositions are new since the protonated conductive polymer is insoluble and, therefore, without using the methods of this docket the protonated electrically conductive polymer cannot be substantially uniformly dispersed in the dielectric polymer to form an electrically conductive body. In one embodiment the nonprotonated polymer is mixed in a solvent containing the dielectric polymer and a protonating agent. The solution is exposed to energy such as heat which causes the protonating agent to release a proton which interacts with the nonprotonated polymer to make it conducting. Simultaneously, the heating volatilizes the solvent quickly enough to prevent the protonated polymer from falling out of solution to form an electrically conductive body. In another embodiment the protonating agent is the dielectric polymer which is a carboxylic acid which provides the proton to protonate the polymer to the conducting state. In an application of these compositions paint is electrostatically or electrochemically deposited onto the composition.

Abstract: A current mode bus coupler (10) for electromagnetically coupling a terminal unit, i.e., an electronic subsystem, with a data bus cable (24) comprising a twisted wire pair is disclosed. The current mode bus coupler (10) includes a planar coil (16), upper and lower slotted planar shields (20 and 22) and a ferromagnetic core (12). The planar coil 16 and planar shields (20 and 22) are formed in a sandwich (14) of alternating dielectric and conductive layers. Apertures (36, 37 and 38) are formed in the sandwich (14) for receiving the legs of the ferromagnetic core (12), and the planar coil (16) spirals around one of the apertures (37). The ferromagnetic core (12) has at least two legs, one of which is inserted into the aperture (37) around which the planar coil (16) is formed. The ferromagnetic core (12) is disengagable and disassemblable so that the core can be inserted in a loop formed by separating the conductors of the twisted wire pair data bus. The planar shields (20 and 22) which would be connected to a common ground form upper and lower layers of the sandwich (14) and shield the planar coil (16) from external electromagnetic and electrostatic fields. The upper planar shield (20) lies between the planar coil (16) and the twisted wire pair data bus in which the ferromagnetic core (12) is inserted. The apertures of the planar shields (20 and 22) are slotted (58 and 60) so that the shields, which are conductive, do not form short circuits about the legs of the ferromagnetic core (12). The sandwich (14) can include additional planar coils (18) formed about the same (or other) aperture and connected in series by conductively plated through-holes (48).

Abstract: A sense amplifier circuit for sensing a datum read from a mask ROM intended for shortening delays in read time due to the stray capacity of the bit line (B1) is disclosed. The circuit has a charging circuit (2, 3) and a discharging-current path (4, 5, 6). At the beginning of a read cycle, the charging circuit is connected to the bit line to promptly precharge the stray capacity. Subsequently an addressing signal is applied to a word line. If the addressed memory cell is an OFF bit, then the electric potential level of the bit line remains unchanged. If the memory cell is an ON bit, then the discharging-current path turns on, thereby enabling prompt discharge.

Abstract: Piezoelectric elements that can resonate at a certain frequency with a coil are extended and contracted as they are repeatedly charged and discharged. The extending and contracting movements of the piezoelectric elements are amplified and transmitted to move the print wires toward and away from the platen. The waveform of a voltage generated across the piezoelectric element is detected by a monitoring device. Then, the detected voltage waveform is compared with the waveform of a voltage that is produced when the print gap is proper, and lets the user to know the magnitude of the print gap between the distal ends of print wires and a platen at any time during printing operation.

Abstract: There is disclosed a voice message system (104) that employs the automatic number identification, ANI, associated with a calling party. This information is transmitted from a switching system, such as a private branch exchange (102) or central office to the voice message system (104). The calling party's ANI is transferred and stored in an ANI register (111) of the voice message system and is compared with pre-stored numbers contained in a memory and selectively entered therein by a voice message subscriber. If a favorable comparison is made between the stored ANI and a number stored in memory, as inserted by the subscriber, a number of unique control features will be implemented by the system based on the confirmation that the ANI number, as derived from the calling party, compares favorably with the stored number entered by the system subscriber. In this manner the system, by making such a favorable comparison, can now implement special features whereby the message stored by the calling party will receive a priority status. One special feature is controlled playback to the subscriber representing an urgent message status for desired calling party priority. The subscriber can further implement message playback whereby the calling party's actual name is announced to the subscriber during the playback of the message. In another special feature, the subscriber can receive his voice mail or messages from a number of locations other than the subscriber's actual extension, which numbers are stored in memory as entered by the subscriber. In another special feature, the subscriber can implement greetings whereby the calling party receives a greeting recorded specifically for them. In yet another special feature, the subscriber can initiate a callback to the original calling party by pressing a single digit.
