摘要： A method of operating an impact printer having a printhead normally intended to create letter quality characters during one pass across the printing medium at a carriage speed at least three times slower than the carriage speed at which the printer creates draft quality characters wherein the method of operation produces letter quality characters at least 50% faster than the prior art method of operation. To accomplish the throughput increase, the printer is operated in the same faster draft speed for the printing of both draft and letter quality characters. Letter quality characters, however, are created in two passes and the printing medium is not advanced to a next row position until after the two passes. During the first pass, the carriage is moved across the printing medium while printing one of each pair of horizontally close adjacent dots includes in the vertical strokes of the characters comprising a row of characters and a portion of other dots included in the row of characters. During the second pass, the other of each pair of horizontally close adjacent dots included in the vertical strokes of the characters comprising the said row of characters and any remaining unprinted other dots are printed.

摘要： A high speed print pin driver for a dot matrix printer. A U-shaped core having a pair of parallel spaced legs is formed of a plurality of laminations of silicon iron. A rectangular magnetic field-forming coil is on one of the legs. A magnetic flux plate of silicon iron is disposed across the open end of the U of the core between the legs, the flux plate being attached to the other of the legs and in close-spaced adjacent relationship to the one of the legs. The top surface of the flux plate over the other leg is slightly longitudinally beveled and the flux plate has a bore therethrough over the one of the legs and longitudinally aligned therewith. A longitudinal spring-metal beam is disposed along the flux plate, being attached on one end to the beveled top surface and extending out over the flux plate on the other end. The beam includes an armature piece of magnetically attractable material disposed within the bore in the flux plate. The beam tapers from adjacent the armature piece to the other end thereof and has one edge forming a reinforcing rib along the tapered portion. A print pin is carried by the other end of the beam disposed substantially parallel to the one leg of the core.

摘要： The 3-D Model Maker of the present invention is a device that builds three dimensional models of computer generated (e.g., CAD) structures by vector plotting layer-upon-layer applications of solidifiable substances. The layers are formed by expelling minuscule beads of the substances in liquid or flowable phase onto a platform from one or more jets, the jets and platform being relatively movable in X, Y and Z coordinate system. The beads are deposited along vectors, during X/Y relative movement, on the stage, one at a time, layer-upon-layer, to build the model. The jets and platform are moved relatively to one another in accordance with instructions from the computer (controller) to form each layer in the X-Y plane (in a manner analogous to an X-Y vector plotter) and either the stage or the jets may move in the Z direction to allow the jets to form subsequent layers.

摘要： A satellite relay communications system includes a ground relay station arranged so that each message from one subscriber to another is relayed by the satellite relay to the ground relay, processed by the ground relay and then transmitted to the second subscriber by way of the satellite relay. Processing at the ground relay station includes a switching function in which the carrier frequency of each message is changed from the frequency used for transmitting by the subscriber sending each message to the frequency used for reception by the subscriber to whom the message is addressed. This permits each subscriber to use a single transmitting frequency and a minimum number of receiving frequencies.

摘要： An improvement to a dot matrix printer of the shuttle variety wherein a printhead is oscillated from side to side within a printer base. The shuttle is disposed within a ballistic energy transfer device mounted for oscillating movement from side to side in the opposite direction to the instantaneous movement of the shuttle. A rebound spring is operably connected to exert a rebounding force against the shuttle to aid it in reversing direction. Also, a centering spring is operably connected for exerting a centering force against the ballistic energy transfer device. A linear motor is connected for driving the shuttle back and forth in an oscillating motion with respect to the ballistic energy transfer device. Optionally, the linear motor is connected for driving the ballistic energy transfer device back and forth in an oscillating motion with respect to the printer base. The turnaround time of the shuttle is adjusted by adjusting the span of the shuttle or the spring constant of the rebound spring. Linear encoders are provided to determine the shuttle position as the shuttle moves back and forth.
