  • Patent number: 5776171
    Abstract: An input command controller (A) provides logic function selection signals and proportional signals. The signals are generated by movement of a ball member (12) and socket member (14) relative to two orthogonal axes. When the joystick is implanted, a transmitter (50) transmits the signals to a patient carried unit (B). The patient carried unit includes an amplitude modulation algorithm such as a look-up table (124), a pulse width modulation algorithm (132), and an interpulse interval modulation algorithm (128). The algorithms derive corresponding stimulus pulse train parameters from the proportional signal which parameters are transmitted to an implanted unit (D). The implanted unit has a power supply (302) that is powered by the carrier frequency of the transmitted signal and stimulation pulse train parameter decoders (314, 316, 318). An output unit (320) assembles pulse trains with the decoded parameters for application to implanted electrodes (E).

  • Patent number: 5457473
    Abstract: An image display apparatus capable of adjusting a display picture by an input unit through a computer body is disclosed. When the user inputs a control instruction for adjusting the display picture of the display unit by the input unit connected to the computer body, a control signal addition circuit prepares a control signal Sc corresponding to the control instruction and adds the control signal to a video signal R, G or B or a synchronizing signal Hs or Vs produced by a display control circuit during a vertical retrace period. A control signal separation circuit separates the added control signal Sc from the video signal R, G or B or the synchronizing signal Hs or Vs produced by the control signal addition circuit. A display control circuit produces adjustment signals Sa and Sb on the basis of the control signal from the control signal separation circuit to adjust a video circuit and a deflection circuit.

  • Patent number: 5339110
    Abstract: In a sound multiplex broadcast system employing sound multiple signals having a plurality of sound multiplex modes and a display control method therefor, there are detected kinds of sound multiplex mode of sound multiple signals received by the receiver, a sound multiplex mode is set, a demodulated sound output signal of a mode determined according to the mode detection signals and the mode setting signal is selected from demodulated sound output signals attained by demodulating the received sound multiple signals so as to be supplied to a sound output unit, and a kind of sound multiplex mode of the demodulated sound output signal thus selected is displayed on a display unit.

  • Patent number: 5086337
    Abstract: This invention relates to a connecting structure for electrically connecting an electronic part such as an LSI chip to a substrate, its production method and an electronic device using the former. The present invention is particularly useful for connecting electrically a plurality of chips, for which an absorption function of the difference of thermal expansion in a horizontal direction and capability of displacement in a vertical direction are requisite, to a substrate. Moreover, the connecting structure of the present invention can simplify the fabrication process, has high reliability and can be applied to high performance electronic appliances and apparatuses such as electronic computers.

  • Patent number: 5035314
    Abstract: In a gravity rollerway conveyor having a plurality of resilient tired rollers with low frction bearings, the resilient tires are selected for various properties desired for the overall conveyor and are permanently preassembled on metallic cylindrical tubes for stockpiling, so that thereafter they may be selected for a particular job and mechanically force fit or cemented onto the outer race of a standard roller subassembly that has the bearing. In this manner, the secure assembly of the tire can be accomplished without contaminating or deteriorating the bearing or other parts of the roller subassembly.
