Abstract: This invention relates to a vehicle having a pivoted head rest and a pivoted seat back that follows a human head and torso forward during the accident of the vehicle, but prevent backwards motion. A U-shaped air bag, the head rest, and seat back prevent whip-lash and also side-impact-whip-lash by immobilizing the head and torso during a frontal or side impact crash.

Abstract: Simple AC circuitry driving a brush-less motor having a rotor consisting of alternate polarity permanent magnets poles, with the rotor journaled in a stator with a like number of wound poles having only two free ends for energizing. The motor is using only two AC electronic switches for starting and accelerating, and an AC switch to run the motor at synchronous speed. It has higher efficiency than previously known circuits, uses less parts and is less costly.

Abstract: A gas generator with the sole input of air, water and coal that continuously produces hydrogen and carbon monoxide and further reacts these two gases into alcohol. This gas generator/reactor is using its own by-products and is therefore also self sustaining.

Abstract: An in-expensive method to join metals or other materials by a slug that is compressed or clinched into a punched or machined substantially rectangular slot in two adjoining pieces. The final assembly is flat and of the same thickness as the clinched material. It could be used to advantage in a mitered frame type assembly.

Abstract: 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.

Abstract: A fast acting re-settable and low cost circuit breaker without moving parts. It has a magnetic amplification feature, and can also be used as a current limiter or current sensor. The fast acting switching function is provided by a Hall device with a binary output actuated by a coil. It is operating within microseconds and can be used to protect semiconductors from destruction by overloads. Integrated circuit fabrication processes can be used for manufacturing of this invention. This device can be used on both direct current and alternating current.

Abstract: 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.

Abstract: 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.

Abstract: The belt of a rectangular two-reel tape cartridge is stretchably entrained around the tape packs, a single belt-driving roller, and four idler rollers. Each idler roller is positioned near a corner of the cartridge so that the belt has an angle of wrap of at least 150 degrees at the periphery of each of the tape packs. Such angle of wrap permits the cartridge to employ magnetic recording tape that has a smoother backside and yet avoids read/write errors at high tape speeds.

Abstract: A corner roller tape tension enhancer assembly for use with a corner roller in a belt driven magnetic tape cartridge. The assembly comprises a cylindrical corner roller having an outer wall for contact with a drive belt and an inner wall suitable for mounting the corner roller on an axial mounting structure. The assembly also comprises a fatigue resistant metal spring positioned against a portion of the corner roller for controlling magnetic tape tension and to produce a uniform tape tension with respect to drive force over a wide speed range.

Abstract: Mechanical incompatibility features between a first and a second belt-driven magnetic recording tape cartridge comprise a shorter rail-mating channel and a countersunk lip in one of the side walls of the first cartridge. The features prevent the first cartridge from being inserted into a tape drive for reading the second cartridge, and vice versa, in order to mechanically distinguish between belt-driven cartridges containing magnetic tapes with different recording characteristics, but having the same form factor.

Abstract: Stretched surface recording disk (SD) 10 comprises an annular support 12 having raised annular ridges 42 and 28 at its inside and outside diameters 22 and 30 with a base portion 24 in between the two ridges, and an annular recording medium film 14 held in radial tension and stretched across the base portion by adhering the film to attachment surfaces 48 and 36 near the inside and outside diameters respectively. The SD is annealed twice during manufacture to relieve stress in the stretched film 14. This annealing results in SD essentially free from track anisotropy and stress distribution anisotropy in the plane of the disk. As a result, data tracks are more stable than in previous SD, track density can be greater, and the SD is generally more reliable.
