Abstract: ABSTRACT OF THE DISCLOSURE   The invention relates to a MNOS memory cell arrangement in VLSI (very large scale integration) technology comprised of a multi-layer gate insulating layer covering a surface of a semiconductor body in the region between the source and drain zones. In order to avoid breakdowns at the source and drain zone edges before an  erasure voltage is attained, the gate elec-trode is split into two electrodes, which can be operated in different ways and which are superimposed one upon another. These gate electrodes are connec-ted via self-aligned, overlapped contacts. This arrangement avoids "short channel erasure", even in the case of VLSI technology. The invention can be applied as required to MNOS EEPROM memory devices.

Abstract: ABSTRACT OF THE DISCLOSURE     A snap on bottle cap for a container having a neck configuration including an annular shoulder over which the bottle cap is engaged so as to be self-retaining thereon.  The bottle cap is formed of resilient material permitting distortion of the cap when it is applied to the bottle.  A ring is positioned around and fastened to an annular flange of the cap by a plurality of frangible elements and it is attached to a portion thereof separated from the remainder by spaced cutaway areas. The ring thus may be used as a pull ring to free the portion of the annular flange as necessary in removing the cap by permitting the remainder of the cap to expand circumferentially so as to become disengaged from the annular shoulder on the neck portion of the bottle.  The separation of the ring provides a visual indication of tampering.  The spaced cutaway areas are a pair of circumferentially spaced vertical slots in the annular flange of the cap and the area therebetween forms a hinge between the cap and the ring.  This invention is distinguishable from others by reason of the arrangement of the ring on the annular flange of the cap which at first reinforces the same and when pulled away from the cap acts to impart motion to the portion of the annular flange to which it remains attached so that the annular flange may expand to free the cap from a bottle.

Abstract: TITLE:  TOY MOVABLE BY ALTERNATELY RELOCATING        INDIVIDUAL MEMBERS OF A PAIR OF BODY PARTS                ABSTRACT    A toy has a first body section and a second body section which are preferedly each shaped as one unit of a matched pair; for example, a pair of shoes.  A crank extends transversely between the bodies and is rotatably connected to each.  The crank includes a first crank section and a second crank section connected together by a connecting section such that the first and second crank sec-tions are parallel but non axial.  One of the bodies, because they are connected together by the crank, can be located longitudinally in front of the other body.  Upon rotation of the crank the second body moves through an arcuate pathway until it is located in front of the first body.  Then the first body moves through an arcuate pathway to once again locate it in front of a second body.  Each of the first and second bodies includes a surface engagement member which is capable of engaging the support surface such that when the first body moves through its arcuate pathway and a portion of its weight is lifted above the support surface, it is not capable of tilting the second body with respect to the support surface and vice versa for the surface engagement member associated with an other body.

Abstract: ABSTRACT OF THE DISCLOSURE         Process are provided herein for producing highly water-absor-bable and water-retainable hydrogels having a large particle diameter together with a sufficient gel strength.  The process involves the use of a specific dispersing agent in the water-in-oil type inverse phase suspension polymerization in an organic solvent polymerization medium of an .alpha. , .beta. -unsaturated carboxylic acid and/or its alkali metal salt in the presence or absence of a cross-linking agent.  The improvement involves using a carboxyl-containing polymer having an affinity to the organic solvent which is used as the dispersing agent.   Due to the high water-absorbability and water-retainability, along with the superior gel strength and the stable gel structure, the hydrogels provided herein enlarge the conventional range of usages.  Thus, they may be used for various sanitary materials, for example, disposable diapers, tampons, sanitary cottons, bandages, napkin and other usages where they contact the human body, without any obstacle.  They may also be used in various commercial uses, for instance, separating agent for water in oil, other dehydrating or drying agent, water-retaining agent for plant and soil, liquid chromatography carrier and other usages where its water-absorbing and water-retaining abilities are utilized.  The hydrogel may be added with coloring agents perfumery or other additives or various inorganic and inorganic fillers.  Furthermore, the hydrogel may be used compositely with paper, fiber, textile and other different materials.

Abstract: BRUSHLESS DIRECT CURRENT MOTOR WITH     MAGNETICALLY OPERATED COMMUTATING SWITCH MEANS                        ABSTRACT         Current to the stator coils of a brushless DC motor is commutated by making transistors alternately conductive by current through magnetically actuated switches.  These switches are actuated by magnetic fields from the permanently magnetized poles of a magnet attached to, but spaced from the rotor and the stator poles.  Depending on the polarity of the magnetic fields, the switches permit one of the tran-sistors to be biased by a voltage source that causes that transistor to become conductive and, simultaneously, connects the base of the other transistor to a voltage that causes that transistor to become non-conductive.  Conductivity of the transistors alternates as the rotor rotates.
