摘要： Describes a new method for saving 65% of material in fabricating electro-magnetic coils. Made as a series of linear open jaw winding coil slots, in a sheet, with the individual coils connected together with bendable remnants. Several of these sheets can be combined to achieve the desired height, for the best thickness of the coil structure. The individually wound coils can be used as separate coils, in solenoids or in electro-magnetic relays, or combined as a stator, The “connection together” is accomplished by bendable remnants, which can be formed into a circle, and used as a stator. If used with a magnet rotor, the lack of winding slots minimizes “cogging”.

摘要： This invention is a new single piece dental prosthetic, a root section connected to the decorative crown section, becoming one part, with a bifurcated root for better anchoring and cleaning action, characterized by: Its simplicity makes it less expensive, and affordable by persons of limited means. Simpler, easier implementation than previous systems. This reliable system provides a new type of anchoring. The present invention is a reliable system with several fastening systems.It is also new way to make an implant less costly, and therefore more affordable by poor persons of low income status. This is done by simplifying the above mentioned procedures, and using new method's such as bifurcation and circular ridge fastening.

摘要： A single coil, direct current permanent magnet brushless motor including a stator including six alternately-wound coils connected into a single coil having first and second ends, the oppositely-wound coils forming stator poles, and six magnets of alternating polarity coupled to a rotor and rotatably journaled in the stator. A sensor, such as a dual output Hall sensor, is used for sensing rotation of the rotor. A drive circuit, such as an H-bridge circuit, is coupled to the first and second ends of the single coil to drive the motor. The H-bridge circuit includes two high-side switches for alternately receiving signals from the Hall sensor, and two low-side switches alternately receiving signals from the Hall sensor. A high-side switching signal can be controlled by an inverted low-side switching signal. A voltage boost circuit is also provided, having capacitors to provide a boosted voltage to alternately turn on the high-side switches of the H-bridge. The capacitors can be charged by an unregulated bus voltage.

摘要： An alignment and latching apparatus for a drive mechanism for data tape mini-cartridges. The alignment and latching apparatus enables the drive to use a new mini-cartridge while retaining backward compatibility with older smaller mini-cartridges. The mini-cartridges have a plastic top cover and a rigid metal baseplate. For some embodiments, an alignment datum is defined by three reference points on the bottom of the mini-cartridge baseplate. In other embodiments, the alignment datum is split with two reference points on the top of the baseplate and one reference point on bottom of the baseplate. Alignment and latching forces are applied on both the plastic cover and onto the baseplate. In some embodiments, alignment force on the top cover is provided by flat springs. In alternative embodiments, alignment force on the top cover is provided by spring loaded rollers. Alignment force on the baseplate is provided by rollers or cam surfaces, pushing upward if a split datum is required and downward if a bottom surface datum is required.

摘要： Improved data protection features for a magnetic recording tape cartridge comprise a recess in the cartridge shell and a movable "file protect" device, which may be a rotatable plug or slidable member. The features enable tape drives to distinguish between two types of cartridges with otherwise identical form factors, allowing one of the cartridges to contain a recording tape with different characteristics that require the tape drive to identify the characteristics of the tape prior to use.

摘要： A circular, shape-retaining cover is fastened to the hub of a rigid recording disc to provide a cartridge. The cover rotates with the disc and undergoes snap-action between a normal conical shape enclosing the periphery of the disc and an inverted conical shape providing free access to the recording surface from the entire periphery of the disc.

摘要： This is a machine with unusual odd-numbered stator coils, and an automatic start position by a single stator-mounted magnet, allowing one (or 2) semi-conductors to start and run the alternate north and south rotor to run efficiently.
The rotor always stops in a start position by magnetic attraction.
The single magnet is also generating power during running.
The stator can be produced with 40% less material, and 40% less cost.

摘要： This invention is for an inexpensive and cost-effective way to patrol and prevent un-authorized personnel from entering or crossing a special one-way roadway. By having continuous surveillance, with the patrol-vehicles having photo equipment, infra-red equipment, radio equipment for contacting proper authority, and having a siren equipped vehicle, it is unlikely for un-authorized personnel from entering or crossing the one-way roadway.The road way is having a left and right fence, preferably made with transparent panels, allowing for visual and infrared surveillance. This surveillance allows for instant detection of any un-authorized person or equipment,The preferred patrol is with a vehicle that is electric and driverless. Signage stating of an addition of an electrified wire, similar to “animal-prevention-fence” prevents personnel from entering the roadway.
