Abstract:
A resonator comprising a single crystal plate of lithium tantalate, lithium niobate or the like is provided having electrodes formed on the plate, the electrodes being multiple layers including gold, chromium, copper and chromium. A novel method of forming such a resonator is also disclosed.
Abstract:
A GASEOUS GLOW INDICATOR TUBE INCLUDING METHOD OF MANUFACTURING AND AGING IN WHICH THE ELEMENTS OF THE INDICATOR ELECTRODES ARE ARRANGED IN A SINGLE PLANE BY PLATING CONDUCTING SEGMENTS ON A BASE INSULATING PLATE WHICH ALSO CARRIES A PLURALITY OF ELEMENT ENERGIZING ELECTRODES. THE VARIOUS ELEMENTS OF THE INDICATOR ELEMENTS ARE INDIVIDUALLY CONNECTED TO THE ENERGIZING ELECTRODES BY STRIP CONDUCTORS WHICH ARE
MOUNTED ON A LAYER OF INSULATION WHICH OVERLIES THE ENERGIZING ELECTRODES. ANODE ELECTRODES ARE MOUNTED ADJACENT THE INDICATOR ELECTRODES AND ARE CONNECTED TO ANODE ENERGIZING LEADS SO AS TO SELECTIVELY ENERGIZE VARIOUS INDICATIONS. A METHOD FOR AGING THE GASEOUS GLOW INDICATOR IS ALSO DISCLOSED.
Abstract:
An indicator display tube in which indicator electrode units, each consisting of anode and cathode segments, lie in the same plane and in which all of the cathode segments are simultaneously energized and the anode segments are energized on a time sequential basis in such a manner that only the indicator electrode unit having its anode segments energized will glow at a particular time. The cathode segments of each indicator unit are connected in parallel. The indicator display tube has barrier segments for preventing accidental discharge of adjacent indicator electrode units which would produce erroneous message displays. At least the cathode but preferably all of the segments are formed of a silver paste coated with nickel. The base material on which the silver paste is coated is glass. This arrangement prevents sputtering.
Abstract:
An indicator display tube in which indicator electrode units, each consisting of anode and cathode segments, lie in the same plane and in which all of the cathode segments similarly located in each unit are simultaneously energized and the anode electrodes are energized on a time sequential basis in such a manner that only the indicator electrode unit having its anode electrodes energized will glow at a particular time. The cathode segments of each indicator unit are connected in parallel which substantially reduces the number of leads to the display tube over conventional indicators which require a separate lead for energizing each of the cathode segments. The indicator display tube is designed dimensionally and otherwise for preventing accidental discharge of adjacent indicator electrode units which would produce erroneous message displays. The tube has each indicating unit preconditioned in advance of each firing to shorten the turn on time of each indicator unit.
Abstract:
IN A NUMBER AND SYMBOL DISPLAY SYSTEM FOR A COMPUTER, THE DIGIT PORTIONS OF A REGISTER ARE SEQUENTIALLY SUPPLIED WITH CODES RESPECTIVELY REPREENTING THE DIGITS OF AN EFFECTIVE NUMBER TO BE DISPLAYED WITH THE CODES REPREENTING ANY FUTILE "0''S" BEING DISTINCTIVE IN RESPECT TO THE CODES REPRESENTING ANY "0''S" IN SUCH EFFECTIVE NUMBER, A DISPLAY DEVICE RESPONDS TO THE SEQUENTIALLY SUPPLIED OUTPUT OF THE REGISTER TO DISPLAY AT ITS RESPECTIVE DIGIT PORTIONS THE DIGITS OF THE EFFECTIVE NUMBER REPRESENTED BY THEIR RESPECTIVE CODES IN THE REGISTER OUTPUT AND AVOIDS THE DISPLAY OF ANY FUTILE "0''S" REPRESENTED BY THEIR DISTINCTIVE CODES, THE DISTINCTIVE CODE IN THE REGISTER OUTPUT IS DETECTED AND, IN RESPONSE TO SUCH DETECTION, A CONTROL OUTPUT SIGNAL IS SUPPLIED TO A DISPLAY DEVICE AT A DIGIT TIME POSITION THAT IS ONE OR TWO DIGIT TIMES LATER THAN THAT OF THE MOST SIGNIFICANT DIGIT OF THE EFFECTIVE NUMBER AS DETERMINED BY THE DETECTED DISTINCTIVE CODE TO CAUSE THE DISPLAY DEVICE TO DISPLAY THE SYMBOL REPRESENTED BY A SUPPLIED SYMBOL CODE IN THE DIGIT POSITIONS HIGHER THAN PLAY DEVICE THAT IS ONE OR TWO DIGIT POSITIONS HIGHER THAN THAT OF THE DIGIT PORTION DISPLAYING THE MOST SIGNIFICANT DIGIT OF THE DISPLAYED EFFECTIVE NUMBER.
