    Abstract: A serialization process presents an efficient method of creating serial numbers on a ceramic-like semiconductor wafer by forming a non-rigid photomask that incorporates character specifications for the serial numbers. The non-rigid photomask is retained in a rigid, optically transparent photomask holder that enables the photomask to be handled as a rigid structure. Upon preparation of the wafer, the serial numbers are created onto wafer dies using a combined process involving photolithography, and a reactive ion etching process with a selective etch rate. The serialization process enables a rapid creation of serial numbers, with the selective RIE process substantially increasing the optical contrast of the characters without the need for deep trenches and without generation of excessive debris.

    Abstract: A transducer for a hard disk drive system has a planar magnetic core and a pair of poletips that project transversely from the core for sliding contact with the disk during reading and writing. The transducer is formed entirely of thin films in the shape of a low profile table having three legs that slide on the disk, the poletips being exposed at a bottom of one of the legs for high resolution communication with the disk, the throat height of the poletips affording sufficient tolerance to allow for wear. The legs elevate the transducer from the disk sufficiently to minimize lifting by a thin air layer that moves with the spinning disk which, in combination with the small size of the thin film head allows a low load and a flexible beam and gimbal to hold the transducer to the disk. The transducer includes a loop shaped core of magnetic material that ends at the poletips, the core extending further parallel than perpendicular to the disk surface and preferably being formed of a plurality of slightly spaced ribbons of magnetic material in order to increase high frequency permeance. A high magnetic saturation layer may be formed adjoining the gap in at least the trailing poletip, in order to avoid saturation at the poletips during writing. The dimensions of the yoke adjacent to the poletips are also designed to avoid saturation at the poletips by saturating at a lower flux in the yoke than the poletips. The close relationship between the transducer and the media of the disk affords high density magnetic data storage and retrieval.

    Abstract: A carburetor for internal combustion engines has a toroidal fuel evaporation chamber which is defined by an outer cylindrical housing and an inner intake tube shorter than the housing. The carburetor further comprises a bottom wall or floor and an upper wall or roof, which together with other elements define the evaporation or wick compartment and a mixing chamber, as well as a plurality of intake orifices with adjacent inwardly opening valves in the upper wall or roof and about the periphery of the cylindrical housing in the region of the mixing chamber. Throttle plug means are reciprocal in guide means and cooperate with the upper wall member or roof to define a selectively variable throttle opening. A level control device maintains a pre-determined fuel level in the evaporative chamber wherein appropriate wick means are provided for the release of fuel vapor into the air drawn into the mixing chamber of the carburetor, and thence into the engine intake manifold.

    Abstract: A solvent piston 22 shuttles between first and second positions. In the first position, high pressure air applied to the rear 22a of the solvent piston 22 closes a solvent bore 24 around the solvent piston 22 and prevents passage of solvent into the mix chamber 26. In the second position, high pressure air is applied to the front 22b of the solvent piston 22 causing it to retract slightly thereby uncovering the solvent bore 24, closing off the solvent inlet 28 and allowing a slug of solvent to mix with the purge air 32 and pass from the solvent outlet 30 into the mix chamber 26. The solvent is either self contained in the applicator or plumbed eternally to the gun.

    Abstract: A spray gun designed for high volume low pressure (HVLP) use is provided with a simple yet effective mechanism for providing feathering as well as allowing for extended needle and nozzle life. A poppet member is spring biased and moves some distance to first initiate air flow prior to initiation of fluid flow. The needle nozzle combination is provided with geometry such that the location of highest velocity is separate from the seating area so as to minimize wear of the seating areas and thus extend life. A two stage pressure drop is utilized for use with plant air. The two stage drop provides more consistent results.
