Abstract: A mask or reticle for a single large microcircuit device is imaged in portions by an axially centered photolithographic reduction lens having a movable mask stage in addition to a movable wafer stage so that the portions of the complete device are imaged in juxtaposed registry on the wafer. This allows a single microcircuit device larger than the image field of the reduction lens to be imaged in a scanning mode or in a succession of steps forming images at the desired resolution range of 0.1-0.50 .mu.m.

Abstract: The method of making refractory ceramic products in which a slurry is formed of water, powdered alumina, and amorphous fibers containing AL.sub.2 O.sub.3 and SiO.sub.2, the volume of water in the slurry being sufficient to permit the slurry to flow under vibration but insufficient to permit the slurry to flow without vibration, the fibers having a molecular ratio of Al.sub.2 O.sub.3 to SiO.sub.2 substantially less than 3 to 2 and the molecular ratio of Al.sub.2 O.sub.3 to SiO.sub.2 in the combined slurry being at least 3 to 2, thereater placing the slurry in a liquid absorbing mold and vibrating the slurry to fill the mold, then permitting the mold to absorb a portion of the water from the slurry to form a body, then removing the body from the mold and drying the body, and thereafter heating the body to combine silica and alumina from the fibers and powdered alumina to recrystalize the fibers in the from of mullite.

Abstract: The present invention relates to filler tubes and, more particularly, to fuel filler tubes and methods of attaching them to automobile fuel tanks. The fuel filler tube of the present invention includes an inlet tube, a retainer member, sealing means and a fuel tank having a downwardly extending diameter portion. The retainer is disposed over the downwardly extending diameter portion and adhered to the tank. The inlet tube is then inserted into the fuel tank aperture until the inlet tubes annular flange engages the fuel tank's annular lip. A crimping tool is then inserted through the axial bore of the inlet tube and a plurality of bearings contained on the crimping tool are forced radially outwardly to thereby crimp the inlet tube and downwardly extending diameter portion together. The retainer member includes a plurality of recessed areas for hosting the expanded inlet tube and tank portions.

In one improved uniformity embodiment for ion-dominated processes, the apparatus of the invention includes a high-energy-density uniformizing grid having multiple, multi-sized and evenly-spaced holes. In one improved uniformity embodiment for chemically-dominated processes, the apparatus of the invention includes a high-energy-density uniformizing grid having multiple, evenly-spaced holes and a stepped or continuously-variable non-planar profile. In one improved low pressure embodiment for ion-dominated and/or chemically-dominated processes, the apparatus of the invention includes a high-energy-density grid having multiple, evenly-sized and spaced holes of widths large enough to overcome dark space effects.

Abstract: A multipoint, multiple function recorder which can record, display, and process up to 135 input/output data points, either analog or discrete, in various combinations. A strip chart recorder is provided for permanently recording input and output data points and, in conjunction with the chart recorder, a separate programmable dot matrix display is provided, such display being responsive to the same input/output data points and operable for displaying data in both alphanumeric and graphic form, the display being independently operable from said chart recorder, such that said input/output points are displayable at different times from the times when they are being printed on the chart recorder.

Abstract: A viewport assembly having a tubular member, such as a ullage tube, with an internal cylindrical surface, a frame ring with an outer and an inner circumferential surface, the outer surface being defined in part by an outwardly radially extending flange portion and the frame ring having a plurality of spaced apart bolt holes therethrough, a gland ring having an integral forwardly extending tubular portion, the tubular portion being telescopically receivable on the frame ring outer circumferential surface rearwardly of the flange portion and providing an annular area externally of the frame ring between the frame ring flange and the gland ring tubular portion forward end, a transparent window disc sealably received within the frame ring, and a bolt for each of the bolt holes in the frame ring threadably engaging matching threaded bolt holes in the gland ring so that as the bolts are tightened the gland ring is drawn onto the frame ring, compressing the packing ring to expand it outwardly into sealing engagement

Abstract: A motor assembly apparatus which includes a housing, an output shaft, a brush assembly, a stator, and a male connector disposed within the housing. The male connector includes a first lug and a second lug and apparatus for connecting the male connectors to the brush assembly and to the stator. In some forms of the invention the male connectors are spade lugs which may be coplanar axially aligned, and the apparatus for connecting the male connectors may include a first planar portion and a second planar portion. The first planar portion is coplanar with the spade lugs in some forms of the invention and the second portion is disposed in oblique relationship to the first portion. The housing may include first and second slots dimensioned and configured and aligned respectively with the first and second spade lugs to allow entry of associated mating electrical connectors.

Abstract: A compensating coupler uses spring coupling legs and tabs to connect a rotary (reciprocating) input drive to a rotary (reciprocating) output drive. The coupler exhibits very low backlash and compensates for misalignment between the input and output drives.

Abstract: Process for the remanufacture of transformers of the type having a coil/core assembly immersed in a tank of mineral oil. Contaminants such as water, air and dirt are removed from the coil/core assembly by means of a hot mineral oil bath which is maintained in a temperature range between the boiling point of water and the boiling point of the mineral oil, typically 212.degree. F. to 295.degree. F.

Abstract: A ticket processing device for use on a mass transportation vehicle. A housing, has a substantially horizontal top, provided with an opening therein for receiving a stack of flat cards, and a slot, for accommodating tickets, at said top of said housing spaced from said openings. Within the housing is a U-shaped pathway having a central axis, the central axis of the pathway being linear through a first, vertical portion thereof adjacent to the opening, an elongated cartridge, for accommodating said stack of flat cards, disposed within the first, vertical portion of the pathway. The cartridge has a slot on one sidewall, adjacent the bottom of said cartridge, for permitting the lowest card in the stack at a given time to be expelled.

Abstract: An improved expendable oxygen sensor particularly useful for measuring the dissolved oxygen content of an aluminum killed, high silicon steel bath is disclosed. The device has the typical closed end tube of solid electrolyte containing oxygen reference material, but differs from previous sensors in that a shield is provided which protects the solid electrolyte from being in contact with the bath until the solid electrolyte has had a chance to heat up more closely to the temperature of the steel. This shield, in one form, consists of a closed end tube positioned to surround the solid electrolyte and spaced from the solid electrolyte in order to prevent erroneous outputs from the sensor due to oxidation of the shield material.

Abstract: Optimum solutions for three-mirror lenses for projection lithography cameras using X-ray radiation to image a mask on a wafer are represented as single points within regions of two-dimensional magnification space defined by the magnification of a convex mirror as one coordinate and the ratio of the magnifications of a pair of concave mirrors optically on opposite sides of the convex mirror as another coordinate. Lenses within region 30, 50, and preferably within region 40, 60, of such magnification space represent potential solutions that are optimizable by standard computer optical design programs and techniques to achieve extremely low distortion lenses having a resolution of about 0.1 micron or less.
