Abstract: This invention pertains to novel copolyesters consisting essentially of units (I), (II), (III) and (IV), and blends of these polymers and articles made from both. Units (I), (II), (III), and (IV) are present in specified proportions as defined in the description of the invention. The instant copolyesters display orientation in the molten state, good fiber ratings and high strength. Advantageously, the polymers of the present invention display a significant improvement in viscosity and moldability of the neat polymer. The polymers have excellent mechanical and surface properties including blister resistance, strength, toughness, and ability to vapor phase solder, and form strong fibers while still maintaining a high heat distortion temperature. They have melting points in the range of from about 250 to about 360 DEG C and are melt-processible. Advantageously, these compositions filled with about 30 weight percent of glass fibers display heat distortion temperatures of up to 240 DEG C, when measured under a load of 264 psi. The polymers may be blended to tailor properties. These polymers and blends may be used advantageously in producing fibers and in electrical equipment, electronic components and other end uses requiring moderately high temperatures.

Abstract: An alloy layer (2) comprising germanium and silicon is grown on top of a silicon substrate (1). The alloy layer (2) is kept thin enough for proper pseudo­morphic, dislocation free growth. A layer of silicon (3) is applied to the alloy layer (2). The initial silicon layer (3) is from two to three times as thick as the alloy layer (2). Approximately the upper two-thirds of the silicon layer (3) is oxidized, either thermally, anodically or by plasma anodization. The silicon layer (3) that remains between the silicon dioxide (4) and the alloy layer (2) is kept thin enough so that a parasitic channel does not form on the interface between the silicon and the silicon dioxide. The germanium alloyed channel (9) is thus suitably bounded by silicon crystalline structures on both of the channel layer (2) surfaces. The barrier heights between silicon dioxide and silicon are very large thus providing good carrier confinement. A suitably applied voltage will result in a region of high mobility charge carriers at the interface (5) between the alloy layer (2) and the upper silicon layer (3).

Abstract: The differential current circuit breaker contains a summing current transformer (2) whose inductance, together with a measurement capacitance (8), forms a resonant circuit whose power absorbtion varies with the amplitude of a fault current IF and has allocated to it a full-wave rectifier (21), with diodes (22 to 25), and a comparator (34). According to the invention, a compensation current IK, which is independent of the fault current IF, is specified for the comparator (34) to compensate for the temperature response of the diodes (22 to 25). This compensation current IK may preferably be derived from a voltage divider (40), which contains a temperature-dependent resistor. In this embodiment, the output signal of the differential current circuit breaker is independent of large fluctuations in the environmental temperature. <IMAGE>

Abstract: The closing device comprises a housing (1) with inlet orifice (2) and outlet orifice (3). In this housing is arranged a rotary slide valve (4) for interrupting the passage of free-flowing and pourable material. The slide valve permits the outlet orifice to be closed in a gap-tight manner and at the same time prevents material from passing through the inlet orifice. The slide valve has a closing piece (5) which can be rotated about an axis running approximately perpendicularly to the axis of rotation of the slide valve. The closing piece interacts with the valve seat of the outlet orifice. A pressure spring (10) is arranged at a distance next to the axis of rotation of the closing piece, between the closing piece and the slide valve. When the slide valve is moved, the pressure spring effects a certain rotation of the closing piece without requiring a drive. …<IMAGE>…

Inventor: BOLY JEAN PAUL
IPC: H04L9/06
Filed: 1990-05-21
Abstract: The invention relates to an encipher algorithm on the basis of a secret key, in which use is made of a substitution function, S(n,k), known as S-box, with which a series of n symbols (for example bits) can be replaced by a series of k symbols. On the basis of the secret key, an arbitrary S-box is always generated in order to avoid the use of preselected S-boxes. Such a generation can generally take place in such a way that the substitution result almost certainly does have non-linearity, but not, that it moreover has good statistical properties. These properties will be obtained, either dynamically (figure 1), if the bits of a temporary substitution result (contents of register 3) are moreover combined, via a modulo-2 adder 5, with the bits of a series with a good statistical distribution (contents of register 4) to the proper substitution result (contents of register 6), or statically (figure 2), if a series of n bits (contents of register 2′) to be substituted is combined with the k bits of a series with a good statistical distribution (contents of register 4′) to a series of n + k bits, which is subsequently substituted by means of a substitution function S{n+k,k} of S-box 1′. The advantages are that a preselection of S-boxes with good statistical and non-linear properties can be dispensed with, and that the S-boxes always change and consequently are not known, which will benefit the strength of the encipher algorithm.

Abstract: The present invention provides an easily fabricated optical fiber coupler which can be employed in applications calling for miniaturization. The optical fiber coupler (11) of the present invention is characterized in that, for a defined section in which two or more component optical fibers are thermally fused and elongated thereby forming a fused-elongated region (14) which constitutes the optical fiber coupler, that at least one of the component optical fibers (12,13) is formed from a single mode optical fiber material employed within a parameter range in which the mode field diameter increases monotonically with decrease in the diameter of the optical fiber core. The optical fiber coupler is further characterized in that, when using optical fibers from which a portion of the coating material has been removed thereby exposing the clad, and by aligning two or more of such component optical fibers side by side in a plane and mutually thermally fusing the exposed clad of adjacent optical fibers, after which the fused region is drawn out, thereby forming a fused-elongated region which constitutes the optical fiber coupler, for such an optical fiber coupler, optical fiber material is used in which the softening temperature of the core is higher than that of the clad, and further, for the drawing out of the mutually fused sections, the tension employed is such that by virtue of remaining stress, the refractive index of the core is reduced. By so forming the optical fiber coupler, it is possible to reduce the difference in refractive index between the core and the clad, widen the mode power distribution, and thereby achieve optical coupling between adjacent optical fibers.
