Abstract: ABSTRACT            A cell-organized graphic display  apparatus  is  described in  which  a set of canonical or standard cells is stored in a character generator (17).  A data processor (not shown)  loads character  codes  into  a  character buffer (14) and attribute bits into an attribute buffer (16).   Lines  to  be  displayed are  computed  on  a cell-by-cell basis by the processor using two canonical cells  and  the  computed  character  codes  are stored in the character buffer (14): attribute bits represent-ing displacements of the required canonical cells  are  loaded into  the  attribute  buffer  (16).   During  accessing of the character  generator  (17),  an  adder  (20)  shifts  the  bit patterns  in accordance with the attribute bits.  Optionally a second character buffer (40),  a  second  character  generator (39)  and  a  logic  mixer (37) are used to allow logical com-bining of cell images in accordance with attribute bits.

Abstract: One Device Field Effect Transistor (FET) AC Stable Random Access Memory (RAM) Array Abstract Disclosed is an integrated circuit electronic memory array having a plurality of FET memory cells arranged in rows and columns and formed on the same integrated circuit chip with associated support circuits.  Each memory cell of the array has a capacitive storage region, an adjacent channel region, and a gate region for controlling the trans-fer of binary information through the channel region in and out of the capacitive storage region.  Each memory cell also has a bit line contact region which is shared with an adjacent memory cell.  The word lines are arranged in rows in a substantially equi-distant parallel relationship, each word line pas-sing, in succession, over the storage region of a first one of the memory cells and electrically integral with the gate region of a second one of the memory cells.  The column arrangement of memory cells is interdigitated such that the memory cells asso-ciated with a single bit line are arranged in first and second parallel lines along both the left and right sides of each bit line.  Thus, the bit line is arranged in a zig-zag configuration alternately contacting memory cells arranged along its left and right side.

Abstract: ABSTRACT OF THE DISCLOSURE          The present invention provides a glow discharge heating apparatus comprising a pair of main electrodes opposing each other through a predetermined gap.  An auxiliary electrode is disposed within the gap and an arrangement is provided for causing a pilot glow discharge between either of the main electrodes and the auxiliary electrode and causing a glow discharge between the main electrodes through the induction of the pilot glow discharge to heat a heated liquid with thermal energy injected into the main electrodes. The auxiliary electrode has applied thereto a pulse voltage superposed on a voltage due to the full-wave rectification of an AC voltage.          The pulse voltage rises before a time point where a voltage applied across the main electrodes reaches a glow discharge hold minimum voltage across the main electrodes and also falls before that time point.  The pulse voltage effects the discharge breakdown between the main electrodes and the auxiliary electrode and the full-wave rectified voltage supplies a current for the pilot glow discharge after the discharge breakdown.

Abstract: ABSTRACT OF THE DISCLOSURE              The invention relates to a resetting device on a rotary switch for resetting the latter when the power supply voltage falls below a predetermined limiting value, in which an electromagnet connectable to the power supply and equipped with an armature is provide, and this armature releases or blocks, in dependence on the state of excitement of the magnet, a return mechanism which subjects the rotary switch to a resett-ing from a switching position into a definite starting position.    With such a resetting device, the armature of the electromagnet controls at least one displaceable blocking tappet, which blocking tappet, in the case of a switch located in a switching position different from its starting position and with the armature pulled up, rests against a projection or engages into a depression of at least one restoring mechanism loaded by a return spring and in drive connection with the drive or switch shaft.  In this way, it is possible, to use such a resetting device also for a switch having several switching positions.

Abstract: Abstract A gas compressor of the scroll type is disclosed wherein means are provided for reducing its degree of com-pression as it starts from a standing start in order to re-duce the initial starting torque required.  To this end, passage means are provided which extend through the end plate means of the compressor from a location in communication with the closed moving volumes defined between the wrap elements to a second location in communication with working gas nor-mally at discharge pressure during operation of the com-pressor.  Valve means are associated with the passage means for permitting flow therethrough when the pressure within the closed moving volumes exceeds the discharge pressure at said second location as the compressor starts from a standing start, and for blocking flow therethrough during operation of the compressor when discharge pressure normally exceeds the pressure in the closed moving volumes.  In the preferred embodiment, the valve means comprise pressure responsive valve means operative to permit flow through the passage means when the pressure within the closed moving volumes ex-ceeds the discharge pressure at the second location, and to prevent flow therethrough when the discharge pressure at the second location exceeds that within the closed moving volume. Preferably, the passage means comprise first and second in-dividual passages, each having its own associated valve means.
