Abstract: In cellular MOSFET transistor arrays using a geometric gate construction, deleterious inherent capacitance induced by the construction is substantially reduced by the use of plugs in between adjacent source regions of transistor source rows and adjacent drain regions of transistor drain rows of the array. Embodiments using field oxide, thicker step gate oxide, dielectric materials in a floating gate construction, and shallow trench isolation region plugs are described.

Abstract: A medical instrument uses solid tapered cones mounted to a preferably concave, spherically curved, piezoelectric ultrasound transducer which focuses and concentrates the ultrasound energy to a narrow tip so very high levels of ultrasound can be delivered to the tissue adjacent to the tip. Ultrasound matching layers or variable curvature geometries are employed at the tip aid in transferring the energy from the tip to the tissue. Alternative embodiments employing cooling technology are also described.

Abstract: Methods and apparatus for enabling substantially bloodless surgery and for stemming hemorrhaging. High intensity focused ultrasound (“HIFU”) is used to form cauterized tissue regions prior to surgical incision, for example, forming a cauterized tissue shell around a tumor to be removed. The procedure is referred to as “presurgical volume cauterization.” In one embodiment, the method is particularly effective for use in surgical lesion removal or resection of tissue having a highly vascularized constitution, such as the liver or spleen, and thus a propensity for hemorrhaging. In further embodiments, methods and apparatus for hemostasis using HIFU is useful in both surgical, presurgical, and medical emergency situations. In an apparatus embodiment, a telescoping, acoustic coupler is provided such that depth of focus of the HIFU energy is controllable. In other embodiments, apparatus characterized by portability are demonstrated, useful for emergency medical situations.

Abstract: An integrated circuit process technology for simultaneously forming multiple threshold voltage devices is disclosed. Devices having both high speed and low power consumption can be fabricated for use in integrated circuits having a need for both, such as microprocessors having cache memory.

Abstract: The present invention provides a process for self-limiting trim etch of patterned photoresist that will allow integrated circuit fabrication to achieve smaller integrated circuit component features and greatly reduce final critical dimension drift or variation. Trim time is set in a plateau region of the critical dimension loss process curve.

Abstract: A brass-wind musical instrument mouthpiece. A plurality of nodal enhancers is provided externally about the portion of the mouthpiece between its rim and shank. In an exemplary embodiment for a trumpet, a total of six rings and seven interspersed grooves in the outer wall of the cup barrel region of the mouthpiece are integrally provided. Better intonation is also achieved with the present invention.

Abstract: A performance optimized computer data recording media format and associated control logic method is disclosed. Localized data block recording, such as by concurrent parallel or serpentine recording techniques, is used to create a series of Virtual Volumes on a single physical volume. Physical localization of data blocks records is achieved which tends to minimize access time. Using the Virtual Volume construct, other industry standard data storage systems can be emulated. Many data storage operations requesting physical motion are translated into virtual motion which in turn results in significantly less physical motion than that requested, thereby reducing access times and media and drive apparatus wear.

Abstract: In a thin film process system, an anti-contamination device, anti-flake shield or collimator plate, is fit to a process chamber. By maintaining a temperature differential between the chamber body and the device, or between the device and any adapter used to conform the device to the chamber apparatus, the device expands to maintain a substantially sealing press fit to the chamber body. The temperature differential can be maintained even when the process is finished until it is time to remove the device for cleaning or disposal and replacement.

Abstract: A tape guide device adapted for a magnetic tape transport system is disclosed. A biasable flat spring, mounted on a barrel roller mechanism, frictionally engages the top edge of magnetic tape. The spring is mounted in order to allow simple adjustment of both the force applied to the top edge of the magnetic tape and the contact angle between the tape and the spring at the arc-radius of the barrel roller.

Abstract: A changer method and apparatus for the loading and unloading of data storage modules from a module drive, such as a computer back-up tape drive, is described. To load the drive, the changer pulls a data storage module, such as a DAT cassette, from a magazine by its end, or face, farthest from the drive. To unload a module from the drive, the changer pushes the module by its end or face found furthest in the interior of the drive's module operative station.

Abstract: In a magnetic sensing head with reduced crossfeed interference circuitry, the winding of each half of a magnetic core of the head is wound in the same direction as the other about the core. Each winding is coupled to an individual differential amplifier and the output of each amplifier is fed to another differential amplifier which provides the head output substantially unaffected by interference signals picked up by the head. Both magnetically coupled and stray capacitive interference are compensated.

Abstract: A method and apparatus for priming a thermal ink jet pen is disclosed. Using an ink reservoir fabricated of a foam material, forced air pressure applied to the foam causes ink therein to flow through the foam and into the printhead. A holder for a rubber air bladder operates in conjunction with a pen cartridge holder whereby an air hole in the reservoir container is aligned with the bladder. Manually pushing the cartridge against a spring results in a squeezing of the bladder, causing air to exert a compression-like pressure directly on the foam reservior.

Abstract: The invention relates to a method and apparatus for making low inertia motors useful under circumstances where the load exerting drag on the motor during start-up acceleration may be different from time to time. A ramped drive current as opposed to a conventional constant current limit signal is applied to the motor. The invention is particularly useful, for example, in magnetic tape drives which must adapt to variations in drag between one tape cassette or cartridge and another.
