Abstract: First and second index divider sheets, each having outward tabs vertically offset from one another, and a table of contents page are provided, with first and second labels releasably attached to the front of the table of contents page generally adjacent to but spaced from first and second descriptive field areas of that page. The page is passed through a printer or copier and custom indicia are printed in the same operation on the labels and in the field areas. The labels are then removed by the user and attached by their adhesive backings to the respective tabs on one or both sides thereof. The labels before printing are adhered directly to the table of contents page inward of the descriptive field areas, to a removable carrier strip which itself is adhered to the front of the page or to a tear-away strip at the bottom of the page.

Abstract: An accelerometer is fabricated by forming a proofmass and at least one associated hinge in a silicon substrate by ion implantation and the formation of an oxide support layer below the proofmass, subsequently integrally bonding two complementary proofmass and substrate structures together, and then removing the oxide support layer to leave the proofmass supported by the hinge within the body of silicon material. The proofmass may be electrically connected to a lead extending through an etched recess in one of the substrates; and the proofmass may be electrically isolated or separated from the substrates by an oxide layer and by a change in conductivity type of the semiconductor material where the hinge is structurally mounted to the substrates.

Abstract: A packing machine includes a frame on a bottom of which a motor is mounted which has a rotary shaft laterally protruding therefrom. A sprocket train is securely mounted around the rotary shaft of the motor to rotate therewith. A chain train is mounted in the frame for co-operating with the sprocket train. A first sealing module is mounted on the side portion of the frame and is driven by the chain train for coupling the two opposite edges of the plastic film together. A second sealing module is mounted on the side portion of the frame below the first sealing module and is driven by the chain train for sealing the bottom end of the plastic film. A guiding device is mounted on the side portion of the frame for introducing the plastic film to smoothly move through the first sealing module and the second sealing module.

Abstract: A single-frequency fiber-optic ring laser exhibits improved frequency stability, reduced laser intensity noise, broad tunability and narrow linewidth. The fiber-optic ring laser includes a ring-resonator with a length of single-mode optical fiber, a gain medium of rare earth-doped fiber, a broad-band fiber Fabry-Perot filter for wavelength tuning of the laser, a narrow-band fiber Fabry-Perot filter for suppression of longitudinal ring modes and an optical isolator for preventing interetalon interactions between the tandem fiber Fabry-Perot filters. Selective positioning of the tandem fiber Fabry-Perot filters, relative to the ring laser's gain medium and output coupler, results in laser intensity noise reduction to the standard quantum limit.

Abstract: An inflation apparatus is described for a labeling machine for placing labels on containers. A sealing element seals the opening of a container whereby the sealing element covers the opening without substantial insertion of the sealing element into the opening in the container. A wall in the sealing element defines an opening through the sealing element for passing an inflation gas through the sealing element and into the container. A gas supply and conduit are provided for connecting the gas supply to the opening in the sealing element. The invention is particularly suited to in-line labeling machines.

Abstract: A random access memory has an access time which is longer than the period of read input signals, for example digital video data signals, such that it cannot respond directly to the input signals. The memory has two read address inputs and two outputs which are arranged as separate channels, each of which can access any location in the memory. The access time of the memory is shorter than two input signal periods. The input signals are applied alternatingly to the read address inputs, and output signals constituted by data stored at addresses corresponding to the input signals are produced at the memory outputs by an arrangement of clocked latches such that, although two input signal periods are used for accessing each memory location, the alternating accessing using two channels enables the memory to produce output signals having the same period (at the same frequency) as the input signals.

Abstract: A toy painted with paint containing thermochromic material which changes color as the temperature of the toy varies. Selected portions of the toy may be painted with the thermochromic material to provide a variety of patterns, designs, numbers, letters or other indicia which change color in response to temperature variations. In addition, different portions of the toy may be painted with different paints containing different colored thermochromic materials.

Abstract: A novel channel buffer management scheme for a video decoder minimizes the amount of memory allocated to buffer a video bitstream received from a transmission channel. A channel buffer accumulates picture data encoded in a video bitstream received from a fixed rate channel. Picture data is read out of the channel buffer by a video decoder immediately after a predetermined or expected amount of bitstream data is received by the channel buffer. Picture decoding, reconstructing, and displaying operations are synchronized to permit the transfer of picture data from the channel buffer to the decoder whenever all of the data bits comprising a picture are received in the channel buffer. A microcontroller monitors and regulates the operation of the novel channel buffer management scheme to avoid overflow or underflow of bitstream data in the channel buffer.

Abstract: The invention is a self-contained protective device/system designed to protect the hips, pelvis, buttocks, and coccyx areas of the user. The device may be worn outside of the clothing. Because it is small in size and lightweight, it may be easily put on and removed and does not interfere with body movements. It contains the following components: an inflatable air bag folded into pleats, a battery, a gas cartridge, sensors to determine angular motion and acceleration, a triggering/valve mechanism to release the gas and a relief valve. When the user falls, the sensors automatically release gas from the cartridge and inflate the airbag assembly, forcing the folded pleats to fully cover said areas of the user's body. After use the relief valve is opened to release air from the airbag assembly, the pleats are reinserted into the system and the invention is ready for reuse after the spent cartridge is replaced.

Abstract: Electrically conductive polymeric compositions suitable for fabricating devices for safely transporting volatile chemicals and fuels are disclosed. The electrically conductive polymeric compositions include at least one matrix polymer and an electrically conductive filler material incorporated in the matrix polymer in an amount sufficient to provide the conductive polymeric composition with an electrical conductivity of at least 10.sup.-10 S/cm. The electrically conductive filler material is intrinsically conductive polymer coated carbon black particles. The coating of intrinsically electrically conductive polymer provides a protective shield against loss of particle conductivity, contributes to the overall conductivity of the filler material and enhances the mechanical properties of the filled matrix polymer.

Abstract: Thermally conductive non-metallic honeycomb structures are provided as well as a novel co-corrugation process for their production. The thermal conductivity of the non-metallic honeycomb structures is increased by incorporating unidirectional thermally conductive fibers in the corrugated laminate sheets used to form the honeycomb. Thermally conductive fibers are integrated in the laminate sheets as a unidirectional fiber prepreg which minimizes the number of broken fibers and allows controlled directional heat conductance through the honeycomb structure.

Abstract: A novel semiconductor fabrication chamber includes a quartz vessel and a metal vessel with a resilient sealing member disposed between the quartz and metal vessels to define a vacuum chamber, along with a cooling assembly mounted on a quartz flange extending around the perimeter of the quartz vessel. A liquid or gaseous cooling medium is passed through the cooling assembly to reduce the operating temperature of a portion of the resilient sealing member in contact with the quartz flange during semiconductor fabrication processing so as to extend the useful life of the sealing member. The cooling assembly is secured to the quartz flange using a plurality of clamping fixtures for easy installation and retrofitting.

Abstract: A digital force balanced instrument such as an accelerometer that incorporates a directly digital electrostatic forcer with servo loop plates charged by a digital feedback loop is disclosed. The accelerometer has a proofmass electrode suspended in a cantilever configuration between electrodes on either side thereof, which proofmass is displaced upon acceleration. Each side electrode includes a plurality of electrostatic plates sized in binarily weighted multiples of area. An induced signal in the proofmass electrode is quantized via A/D converter in the feedback loop, which activates the appropriate number of plates to force the proofmass to an initial position.

Abstract: A critical temperature rise .DELTA.R is selected at a value for which electromigration of atoms in the metal conductive line deposited on a semiconductive substrate is predominantly a grain boundary electromigration. Selection of the critical resistance rise is made by performing a number of tests on different ones of a plurality of substantially identical bow tie conductive lines formed of alternating narrow and wide sections interconnected by tapering line sections. Temperatures for the selection of the critical resistance rise are calculated rather than measured so as to more accurately reflect the relatively high local temperature at the site of a void in the metallic conductive line. Plot of a plurality of line widths against temperature for a given current density enables selection of a minimum line width or maximum void depth that will occur in a condition of predominantly grain boundary electromigration and before a large amount of bulk electromigration occurs.

Abstract: A day/night sight includes a visible-light first optical path and an invisible-light second optical path which are everywhere optically coaxial. The invisible-light second optical path leads to a detector or to an image intensifier tube for providing either an electrical signal or a visible image, respectively, in response to the invisible-light image. A third optical path for the visible image from the image intensifier tube is also everywhere optically coaxial with the first and second optical paths. A visible image produced from the electrical signal is introduced into the first optical path to thereafter be coaxial therewith. Consequently, a uniquely compact arrangement of the elements for the day/night sight is achieved.
