Abstract: A twist tie feed device is provided for twisting together the ends of a tie ribbon which encircles a product including a base plate. A twist head assembly is mounted on the base plate and receives a first end of a tie ribbon which encircles the product and a second end of the encircling tie ribbon and will rotate about itself to twist the tie ribbon about the article. Two positive drive wheels feed the ribbon in one of a first direction towards the twist head assembly and a second direction away from the twist head assembly so that the wheels contact the ribbon at its top and bottom to apply a positive drive force to the drive ribbon as it passes between the drive wheels. A drive assembly is operatively coupled to the twist head assembly and the drive wheels for driving the positive drive wheels and twist head assembly.

Abstract: A thermal transfer ink sheet including a heat resistant support film, a first fusible ink layer disposed on the support film, an interlayer which will support the first ink layer in uniform layer condition during thermal printing and will still separate cleanly from the non-printed portion on the first ink layer and a second fusible ink layer on the interlayer. Several embodiments of the interlayer will maintain the first ink layer in uniform layer condition during thermal printing. The interlayer can be formed of: a material with a low melting point whose viscosity does not decrease substantially when its temperature is increased; a thin film of thermosetting resin; and a layer of material formed of minute grains or domains smaller than a pixel which will form a pixel sized layer support during thermal printing.

Abstract: A dual transducer probe for measuring blood flow by Doppler effect measurement in which quantitative flow data can be compiled and flow constriction points as small as 10% and less can be pinpointed with relative ease. The probe is formed with two transducers, oriented at about 45.degree. from a bottom contacting surface of the probe so that transmission signals diverge at an angle of about 90.degree.. A first transducer directs pulsed sound waves into the direction of blood flow and a second transducer directs pulsed sound waves with the direction of blood flow. The transducers act as receivers for the respective pulses. Fluid velocity can be calculated due to the Doppler effect. By analyzing the signal frequency shifts from the two transistors the blood flow at a very minute region between the transducers, can be determined. Constrictions, corresponding to changes in flow can be pinpointed by moving the probe along the blood vessel.

In an alternative embodiment, the deck has at least one outermost area of reduced thickness and at least one non-outermost area of reduced thickness. The outermost area is preferably about half the height of the non-outermost area. In another preferred embodiment, the deck includes at least one outermost area of reduced thickness and at least one non-outermost area of reduced thickness. The height of the outermost area varies from a maximum height near the middle of the deck, to a minimum height near the end of the deck.

Abstract: A disc drive for a disc including a disc rotating apparatus comprising a rotating shaft for being received within a first aperture of the disc. A spindle is affixed to the shaft. The spindle has a surface disposed in a plane perpendicular to the shaft, for supporting the disc. A disc driving means includes a position controlling member received in a second aperture of the disc, a rigid member for controlling the position of the position controlling member, and a biasing member for urging the rigid member in at least one direction so that the position controlling member engages the disc. A centering force to center the disc on the disc rotating apparatus is produced due to the action of the position controlling member on the disc. The biasing member may be configured so as to act upon the rigid member in an additional direction to produce an additional centering force component when the position controlling member engages the disc, thus urging sides of the first aperture of the disc against the rotating shaft.

Abstract: A liquid crystal display device for producing a substantially uniform tone pattern by placing in the same display state all display dots producing the tone pattern which are associated with the same scanning electrode during each frame of a cycle. The method further includes adjusting the scanning waveform applied to each scanning electrode during each frame based on the tone pattern. Alternatively, the liquid crystal display device places all display dots which produce the tone pattern in the lit state for the same duration of time during the cycle and concurrently adjusts the scanning waveform applied to each scanning electrode during the cycle based on the tone pattern. Different groups of display dots which produce the tone pattern are placed in the non-lit display state at different portions of the cycle. Voltage disturbances giving rise to spikes and rounding of the voltage pulses occuring on the scanning and signal electrodes are substantially eliminated.

The photoconductive layer includes a first charge generation layer adjacent to the conductive layer, a charge transfer layer on the first charge generation layer and a second charge generation layer on the charge transfer layer. During exposure, resistance of the photosensitive layer is reduced so that charges can flow through the photosensitive layer to create oppositely charged portions of the image forming member corresponding to a desired image of each color. Appropriately charged color toner adheres to the surface of the image forming member in the form of the desired image. After each color toner image is formed, the completed color image is transferred to a transfer medium.
