Title: Indicator display tube
Inventor: YANAGISAWA YUZURU
IPC: H01J17/49
Filed: 1971-09-10
Granted: 1980-07-15
Abstract: ABSTRACT OF THE DISCLOSURE           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 simul-taneously 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 has a barrier electrode formed so as to lie between adjacent indicator units for prevent-ing accidental discharge of adjacent indicator units which would produce erroneous message displays.

Abstract: ABSTRACT OF THE DISCLOSURE     The present invention relates to a pellet useful for establishing plants on an area of land comprising sowing onto the bare soil, or onto existing herbage on the area of land, a pellet comprising at least one seed of at least one desired species of plant, nutrients sufficient to support the growth of the plant or plants until establishment, and from 10 to 30% by weight of a binding agent selected from clays and hydrophilic organic polymers selected from methyl cellulose, polyvinyl alcohols and alginates, said binding agent when sufficiently moist adhering to the soil to form a cohesive cake therewith, entrapping said seed or seeds; and wherein the nutrient materials are selected from materials that are available slowly to the seed. By the use of this invention desired species of pasture plants including grasses, clovers and lucerne can be established in areas where existing methods would prove too costly and would be precluded by unfavourable climatic and cultural conditions.

Abstract: VELOCITY CORRECTION TRANSDUCER                Abstract of the Disclosure One type of video disc reproducing system senses the capacitance between a stylus and a disc record to reconstruct the video information.  The stylus includes a thin conductive element or electrode and rides in a groove of the record, which is rotated at high speeds.  The record includes a conductive layer covered with a thin dielectric material.  A velocity correction system comprising a closed-loop feedback system provides an advantageous means to vary the position of the pickup means relative to the moving record.  This positioning maintains the relative velocity between the two substantially constant for a given radius from the center of rotation, thus correcting for residual velocity errors.  There is disclosed a transducer apparatus which is mechanically coupled to the signal pickup means and electrically coupled to circuitry providing a velocity error signal.  The transducer has a stationary portion which includes means for generating a magnetic flux.  The transducer also has a second portion which is coupled to the pickup stylus and which is movable with respect to the stationary portion.          The stationary and movable portions are intercoupled by compliant members.  An electrical winding is disposed on the movable portion and is coupled by the magnetic flux such that an electrical current passed through the winding imparts motion to the movable portion.  Electrical damping is provided by a closed-loop conductive member on the movable portion which is coupled by the magnetic flux and is operative to oppose motion of the movable portion.

Abstract: AUTOMATIC CHORD CONTROL CIRCUIT FOR              ELECTRONIC MUSICAL INSTRUMENTS     Abstract of the Disclosure An automatic chord control system is disclosed which is readily incorporated in an electronic organ by means of large scale integrated circuit chips.  The auto-matic chord control causes a chord or group of notes within an octave played on the lower manual keyboard to play through the upper manual voice in the octave below the lowest melody note being played on the upper manual key-board.  The proposed automatic chord control system has two operating modes.  In the first mode, the notes trans-ferred to the upper manual are generated directly by the keys activated on the lower manual.  In the second mode, the notes transferred to the upper manual are generated by a set of preset chords activated by single lower manual keys.

Abstract: DISTRIBUTED FEEDBACK DEVICES WITH PERTURBATIONS DEVIATING      FROM UNIFORMITY FOR REMOVING MODE DEGENERACY            Abstract of the Disclosure Distributed feedback devices such as distributed feedback lasers are modified by introduction of a central coupling strength discontinuity or other deviation from uniform nature of the distributed perturbations, in order to promote the transmission or oscillation of a single mode in preference over the nearest redundant modes.  The class of deviations from uniform coupling strength may be mathematically termed antisymmetric deviations, because they are deviations about the midpoint of the perturbation pattern which result in a distinction of effect of the two halves of the pattern, taking either half as a reference pattern by itself.

Abstract: DYNAMIC UNIFORM FLOOD CORRECTION FOR         RADIOISOTOPE CAMERAS                    Abstract of the Disclosure The intrinsic nonuniformity of a radioisotope camera having photomultiplier tubes substantially adjacent to the scintillator crystal assembly is improved by storing a plurality of integer correction factors from 1 to n for a matrix of loca-tions.  With a uniform flood source, the count at each location is compared with an average minimum count to generate the correction factors.  In operation, the correction factor for a location where a radiation event has been detected is compared to a random number between 1 and n.  If the correction factor is less than the random number, the radiation event is ignored.
