Abstract: An apparatus and method are disclosed for fabricating an expanded beam cylindrically terminated optical fiber taper (36-38) from a reduced diameter preform rod (15). The present invention comprises mounting the reduced diameter preform rod in a first moving arrangement (11, 13, 16, 18, 19, 23) and a second moving arrangement (12, 14, 17, 25-29) and uniformly heating the circumference of a predetermined portion at an intermediate point of the preform rod with a heating arrangement (81) to a predetermined temperature, and then uniformly pulling the preform rod while continuing to heat additional material of the preform rod to produce a pair of expanded beam cylindrically terminated optical fiber tapers (37) connected by a predetermined length cylindrical central section of standard optical fiber (38) having a uniform diameter less than that of the original preform rod. The cylindrical central section is then severed midway between the two expanded beam optical fiber tapers to form two separate expanded beam cylindrically terminated optical fiber tapers comprised of (1) a predetermined length cylindrical end section of uniform diameter (36) equal to that of the original preform rod; (2) a reduced diameter optical fiber end section (38) suitable for splicing onto an optical fiber of similar dimensions; and (3) a tapered section (37), connecting the cylindrical end section to the optical fiber end section, having a gradually decreasing diameter that will avoid mode conversion of a lightwave signal propagating therethrough.

Abstract: In different printed circuit base materials and test directions, two compensated fields of needle arrays are required to scan a core in both directions. The problem of the invention is based on adapting the expansion of the contacting grid to the actual soldering hole grid of a printed circuit board which has to be tested. The solution is to use the thermal expansion of the insulating material used to support the contact needles for the adaptation. Use of strip adapters (length much greater than width). With planar adapters (complete adapter) it is necessary to use an insulating material (or its filling) which has different coefficients of thermal expansion in the x and y direction. <IMAGE>

Abstract: A circuit which responds to the application of a pulse to its input (6) by generating a pulse at its output (3), the output pulse having a minimum duration T and being extended by the remaining length of the input pulse should the input pulse be still present at the end of the time T, comprises a pair of semiconductor switches (1,2) connecting the output (3) to points (5,4) carrying respective logic levels. The input pulse closes the first switch (1) and also inhibits a gate circuit (9). The resulting logic level on the output (3) closes the second switch (2) after delay by T in a delay circuit (13) and transmission through the gate circuit (9), thereby restoring the original logic level. The instant when this occurs coincides with the presence of the delayed output pulse at the output (14) of the delay circuit and the absence of the pulse at the arrangement input (6). A hold circuit circuit (15) may be provided for holding the logic level currently present at the output (3). The circuit may be used as an equalisation pulse generator for a data path in a semiconductor memory integrated circuit.

Abstract: An implantable fluid delivery device (10) for dispensing metered amounts of liquid medication when a pump assembly within its casing is operated by finger pressure applied to a central target zone (54) of the casing's top wall. The top wall also includes an injection site (72) spaced from the central target zone (54) for use when a bolus of medicament is to be injected into the device and delivered directly to the patient without passing through the pump assembly. The flattened pear shape of the casing and the location of the sites for pump activation and refilling on one hand, and for bolus injection on the other, facilitate error-­free use and operation of the device. Although limited fluid backup may occur during bolus injection, a valve arrangement within the device prevents intermixing of the bolus medicament with the liquid medication in the reservoir. In a second embodiment, a supporting grid (80) prevents possible injury to the backup-restraining valve during bolus injection.

Abstract: A portion of the heat of vaporization, required to separate and recover methanol from wash water used to remove methanol from a C₄ raffinate resulting from the reaction of isobutene containing C₄ hydrocarbons and methanol to produce MTBE is recovered by conducting the distillation of the methanol/water mixture at a pressure of 40 to 60 psig, thereby increasing the temperature of the methanol overhead to 104 to 114° C and using the reaction effluent from the MTBE reactor to cool and condense the methanol overhead, said reactor effluent being correspondingly heated prior to entry into a debutanizer tower where unreacted C₄'s and methanol are removed as a raffinate and MTBE product recovered. It is this raffinate that is washed with water to recover the unreacted methanol, with the methanol/water mixture being distilled as set forth above. In another embodiment a stream having a lower temperature than the methanol overhead is withdrawn from the debutanizer and used to cool the methanol overhead, then the correspondingly heated stream returned to the debutanizer.

Abstract: The rod base material for wafers comprises a plurality of rod members made of materials to be used as the wafers used for electronic devices which are assembled in parallel and bonded with each other into an integrated body. Wafers used for electronic devices can be obtained by slicing the rod base material for the wafers. Mirror-finished bonded face is formed to the outer surface for each of the rod members. The bonded face to each of the rod members is cleaned by a surface treatment using chemicals. Subsequently, respective rod members are assembled in parallel and brought into contact with each other at their respective bonded faces. The thus prepared rod base material are maintained in a heated atmosphere into an integrated body. Then, the rod base material is applied with slicing for providing wafers used for electronic devices. Since the rod base material has a structure in which a plurality of the rod members are assembled in parallel and bonded with each other into an integrated body, the diameter for the rod base material can remarkably be increased. Accordingly, the diameter of the wafers obtained by slicing the rod base material is also increased remarkably. Since the wafer diameter is increased remarkably, the cost per one electronic device formed on the wafer is also reduced remarkably.

Abstract: A method and apparatus for performing the square root function is described which first comprises approximating the short reciprocal of the square root of the operand. A reciprocal bias adjustment factor is added to the approximation and the result truncated to form a correctly biased short reciprocal. The short reciprocal is then multiplied by a predetermined number of the most significant bits of the operand and the product is appropriately truncated to generate a first root digit value. The multiplication takes place in a multiplier array having a rectangular aspect ratio with the long side having a number of bits essentially as large as the number of bits required for the desired full precision root. The short side of the multiplier array has a number of bits slightly greater by several guard bits than the number of bits required for a single root digit value, which is also determined to be the number of bits in the short reciprocal. The root digit value is squared and the exact square is subtracted from the operand to yield an exact remainder. Succeeding new root digit values are determined by multiplying the short reciprocal by the appropriately shifted current remainder, selectively adding a digit bias adjustment factor and truncating the product. The root digit values are appropriately shifted and accumulated to form a partial root. Succeeding exact remainders are calculated as the difference between the   previous remainder and the product of the newly calculated root digit value and the sum of the newly calculated root digit value and twice the previous partial root. The described steps are repeated to serially generate root digit values and partial roots with corresponding new exact remainders. If the corresponding final remainder is negative, the final full precision partial root is decremented and the remainder recalculated, yielding the full precision unique partial root and non-negative remainder pair which compose the exact square root.
