摘要:
Disclosed is a shaped article comprising a continuous oriented polymer matrix having dispersed therein microbeads of a polymer which are at least partially boredered by void space, the microbeads being present in an amount of about 5-50% by weight based on the weight of said oriented polymer, said void space occupying about 2-60% by volume of said shaped article. Preferably, the microbeads are cross-linked to an extent they will be resilient and elastic at the orientation temperature, and are coated with a slip agent. The shaped article is preferably in the form of a sheet, fibers, or other molded article, preferably has a relatively low specific gravity and whiteness.

Equipment for towless skiing on water surface includes a pair of propulsion sticks having buoyant members at one end and handles at the other end. The buoyant members provide increased thrust against the hydrodynamic resistance of the water, and the shape of the buoyant members permits removal of the buoyant members from the water with little resistance. The equipment also includes a pair of skis comprised of foam material and provided with stabilizing shoulders on both sides of each ski for minimizing the effect of nose diving and rolling of the skis in the surf. The cross-sectional areas of the buoyant members and of the skis are such that maximum propulsion forces are provided. The skis are designed to endow the surf skier with a greater degree of freedom during surf skiing and to enable the skier to ski for longer distances on the water.

A method of measuring the height of a foot arch precisely and easily using two essential heights of the foot arch is disclosed. In the method, a foot cast is primarily cast by pouring plaster into a foot mold. Thereafter, a first intersecting point and a second intersecting point are determined. The first intersecting point is determined by making a first line and a third line intersect. The second intersecting point is determined by making a second line and the third line intersect. The first line is a straight line extending from the center of the second toe to the center of the heel end. The second line is a straight line extending from the center of the big toe to a point spaced apart inwardly from the center of the heel end by ⅛ of the total distance of the heel end. The third line is a center line of the transverse arch of the foot. Finally, a first height and a second height are measured while the foot pattern is set in an upright position. The first height is defined between a flat base level and the first intersecting point, while the second height is defined between the base level and the second intersecting point.

Disclosed are photographic elements having reflective or diffusely transmissive supports shaped from a continuous oriented polymer phase having dispersed therein microbeads of a polymer which are at least partially bordered by void space, the microbeads being present in an amount of about 5-50% by weight based on the weight of the oriented polymer, and the void space occupying about 2-60% by volume of the support. Preferably, the microbeads are cross-linked to an extent they will be resilient and elastic at the orientation temperature, and are coated with a slip agent. Such supports have excellent physical properties.

An output buffer circuit for an integrated circuit for outputting an amplified signal from a sense amplifier which senses information stored in a memory cell of random access memory for improving operation of the integrated circuit is disclosed. The output buffer circuit comprises NAND gates ND1, ND2 operatively connected to the output of the sense amplifier to receive first and second output signals S1, S2, and operatively connected to receive a control signal .phi.1 from the integrated circuit which operates the memory cell to read. A MOSFET Q1 and a MOSFET Q2 are utilized with both MOSFETs turning on or off depending upon the signals applied to their gates. An output loading capacitor CL is operatively connected to the junction P4 and to the ground. A logic combination means 10 connected to junctions P1, P2 performs a logical combination of the signal applied through the junction P4 and the control signal .phi.1 applied to the input points of the logic combination means. An output means 20 is connected between the logic combination means 10 and the junction P4, thereby controlling the output level of the output buffer circuit to a middle level depending upon the signal from the logic combination means.

摘要:
Desired control of the thickness and composition of a solder coat on the J-leads of an integrated circuit Quad package is obtained by orienting the packages while being solder coated in a "leads-up" orientation as a series of strips mounting the packages are passed through a solder wave of a wave soldering apparatus on a pallet. The Quad or other shaped integrated circuit or other electronic packages which have leads extending exteriorly thereof, thus have the critical lead crest portions coated with substantially the same solder layer thickness and composition. This permits reliable electrical connections between the crest portions of the leads and printed circuit board metal traces (metallization), particularly in surface mounting of the package to a printed circuit board. An additional feature of the invention is a pallet for holding a series of package-holding elongate frames which pallet is used for conveying the packages through the wave soldering apparatus.

A combined storing and slicing device is provided with a rectangular box-like container having one open shorter side through which a stick of butter or the like is received. A cutting line is held in a taut condition and is mounted for movement between a first rest position at the top of the open side and a second position at the bottom of the open side while traversing the open side. A cover is provided for the open side which retains the line in the second position when the cover is over the open side.
