  • Publication number: 20190312180
    Abstract: Printed micro-LEDs have a top metal anode electrode that is relatively tall and narrow and a bottom cathode electrode. After the LED ink is cured, the bottom electrodes are in electrical contact with a conductive layer on a substrate. The locations of the LEDs are random. A thin dielectric layer is then printed between the LEDs, and a thin conductive layer, such as a nano-wire layer, is then printed over the dielectric layer to contact the anode electrodes. The top conductive layer over the tall anode electrodes has bumps corresponding with the locations of the LEDs. An omniphobic liquid is then printed which only resides in the “low” areas of the top conductive layer between the bumps. Any optical material is then uniformly printed over the resulting surface. The printed optical material accumulates only on the bump areas by adhesion and surface tension, so is self-aligned with the individual LEDs.

  • Patent number: 10412833
    Abstract: A programmable circuit includes an array of printed groups of microscopic transistors or diodes having pn junctions. The devices are pre-formed and printed as an ink and cured. The devices have a proper orientation and a reverse orientation after settling on a conductor layer. The devices are connected in parallel within small groups. To neutralize the reverse-oriented devices, a sufficient voltage is applied across the parallel-connected diodes to forward bias only the devices having the reverse orientation. This causes a sufficient current to flow through each of the reverse-orientated devices to destroy an electrical interface between an electrode of the devices and the conductor layer to create an open circuit, such that those devices do not affect a rectifying function of the devices in the group having the proper orientation. An interconnection conductor pattern may then interconnect the groups to form complex logic circuits.

  • Patent number: 5297055
    Abstract: A multi-purpose probe module 82, comprising both a touch-trigger type contact probe 84 and a non-contact type probe 86, is used in method and apparatus for monitoring and adjusting the accuracy of a computer-controlled machine for manufacturing precision bevel and hypoid gears. The probe module is mounted on the machine's tool support and is used in conjunction with locating points positioned on the machine's work support to monitor and recalibrate the relative positions of the tool and work supports. The probe module is also used to monitor the flanks of the gear-shaped workpieces (a) for initial stock division, (b) for pre-machining accuracy, (c) for first-piece testing, (d) for in-process accuracy, and (e) for post-machining accuracy. The same probe module is used in combination with a sacrificial test wafer mounted on the work support for adjusting the position of the machine's cup-shaped grinding wheel following each dressing of the latter's working surfaces.

  • Patent number: 4784894
    Abstract: A composite for constructing an article which is composed of a nonmetallic substance as represented by igneous rock of different particle sizes which are compacted and then surrounded by a solidified plastic resin. In a preferred manner, the igneous rock material is a selected type of basalt with the basalt particles being of different mesh sizes to be compacted into a mold. After compaction, the plastic resin as represented by an epoxy resin is introduced into the mold so as to displace air from any voids surrounding the basalt particles and to surround them with a resin which later solidifies. A novel resin delivery system is also presented.

  • Patent number: 4628441
    Abstract: An automatic dynamic error compensator for compensating the position error arising within a servo drive system includes a measuring head which is operative to measure the relative indicated position of two or more measuring vanes on the movable member. The measuring head, together with a feedback transducer, that measures indicated movable member position, are coupled to a feedback system. The feedback system determines the indicated movable member position from the feedback transducer reading and then compares the indicated movable member position to the known vane position upon occurrence of a vane crossing to yield a compensating value.

  • Patent number: 4533859
    Abstract: A motorized nut for use in conjunction with a fixedly secured lead screw for displacing a movable member along a fixed member into which the lead screw is journaled parallel to the desired path of member movement, includes an induction motor whose case is rigidly secured to the movable member. The motor rotor is made hollow so as to allow the lead screw to extend coaxially therethrough. A pair of nuts are each secured in a separate one of the ends of the tubular motor rotor for threadedly engaging the lead screw so that as the motor rotor rotates in response to motor excitation, the motor stator and hence, the movable member, are displaced on the movable member along the axis of the ball screw.

  • Patent number: 4487087
    Abstract: An improved ball nut having adjustable preloading comprises a pair of ball nut halves both in threaded engagement with a ball screw. Only one of the nut halves is secured to a movable machine member, the other nut half being movable to the relative fixed nut half. Separating the two nut halves is a pair of concentric sleeves, which are each fabricated from a piezomagnetic material such as nickel or nickel alloy. The sleeves are each keyed to the nut halves to prevent one nut half from rotating independently of the other. Between the sleeves is a magnetic coil which, when energized, causes the sleeves to expand. By varying the coil excitation, the sleeve length, and hence, the force exerted on the ball nut halves by the sleeves can be varied accordingly to vary ball nut preloading.

  • Patent number: 4390953
    Abstract: An unmanned diagnostic communications system for analyzing the operation of a remotely situated computer controlled machine tool and for diagnosing any abnormalities disclosed during machine tool operation includes an auto dialer and MODEM coupled between the computer controlled machine tool and one end of a communications channel and an auto answer MODEM coupled between the other end of the communications channel and a diagnostic computer. In response to a test command entered by an operator to the remotely situated computer controlled machine tool or a machine tool initiated test command, the auto dialer automatically establishes a communications link with the diagnostic computer through the auto answer MODEM. Thereafter, the diagnostic computer determines the identity of the remotely situated computer controlled machine and then transmits instructions to the computer controlled machine tool to direct its operation.

  • Patent number: 4266120
    Abstract: A numerically controlled machining center has a tool magazine, automatic tool changer, workpiece shuttle, and a workpiece magazine which holds enough workpieces for operation by the machining center for an entire shift of approximately eight hours. The numerical controls are programmed to perform predetermined machining operations on each workpiece, in turn, and to replace each finished workpiece with a fresh workpiece at the end of each machining program. A proximity switch is mounted on the machining center for checking tools to detect broken or incorrect tools. The tools are positioned adjacent to the proximity switch and are rotated while the output of the proximity switch is counted for one complete rotation of the tool to determine the number of radially extending teeth on the tool. If the tool has too few or too many teeth, thus indicating a broken or incorrect tool, it is replaced by another tool of the same type.

  • Patent number: RE31247
    Abstract: A diagnostic communication system for machine tools interlinks a computer controlled machine tool with diagnostic and analysis equipment located at a location remote from the machine tool. The computer associated with the machine tool is connected with the diagnostic apparatus over a telephone line, and the machine tool is caused to execute a predetermined routine as a result of instructions transmitted to the computer from the diagnostic apparatus. The operating characteristics of the machine are monitored during the operation of the machine, and are communicated to the diagnostic apparatus, where they are compared with corresponding characteristics previously collected for the same machine, and with design limit parameters. Such comparisons furnish an indication of the present operating condition of the machine tool, and establish trends, which are useful in identifying the nature and location of incipient faults or failures before they occur.
