Abstract: A method for optimizing the performance of an ophthalmic progressive lens having a distance viewing zone, a near viewing zone, and an intermediate zone, and the resulting optimized lens are provided. The surface of the lens to be optimized, which has at least one quantitative performance characteristic, is represented by a mathematical base function which is combined with a selected optimization function. The optimization function includes at least one adjustable parameter and may have at least one boundary condition imposed on it along the boundary of a selected subregion of the lens surface. A quantitative merit figure of the combination of the base and optimization functions, which is related to the at least one performance characteristic by a selected merit function, is optimized through the at least one adjustable parameter of the optimization function. Through the optimization, there is obtained an improved surface function which represents the surface of the improved progressive lens. A lens surface responsive to the improved surface function is then formed.

Abstract: The invention relates to porous membranes made of sintered silica or refractory metal oxides, e.g. alumina, titania, zirconia, tungsten oxide, etc., and to a process for their formation. The membranes are formed by dispers­ing a powder of the metal oxide or silica in an organic polymer. The relative amount of silica or metal oxide to polymer is such that, after the polymer has been carbonized in a subsequent step, there is a stoichiometrical excess of the oxide to carbon. The solution is then shaped to form a desired thin membrane, and the polymer is then carbonized by heating it in a non-oxidizing atmosphere. The resulting oxide/carbon product is heated to a temperature at which (a) the carbon reacts with the oxide to form a volatile sub-oxide and carbon monoxide and (b) the remaining (unreacted) oxide particles sinter together. The heating is carried out in a non-oxiding atmosphere containing either no nitrogen whatsoever, or an amount of nitrogen less than that which results in the formation of a non-porous product. The sintered membranes can be used, for example, as filters and catalyst supports and have good strength and controlled porosity.

Abstract: So that there is no need for a temperature sensor provided specially for monitoring the lye temperature in only the wool washing programme, the fixed-temperature sensor provided for monitoring the lye temperature in the prewash programmes can also be activated at the start of the wool washing programme. When a temperature approximately 10 to 15 DEG K below the maximum temperature considered permissible for the washing of wool is reached, the fixed-temperature sensor transmits a control signal for the coupling magnet which then couples the programme roller to the drive again. <IMAGE>

Abstract: The bipolar transistor structure has a vertical emitter/base/collector sequence in which the emitter (13) is connected to a metallic emitter contact (19) via an emitter terminal region (18). The emitter terminal region (18) extends beyond the emitter (13) onto the surface of the substrate (10) containing the bipolar transistor structure. The emitter contact (19) only partially spans the emitter terminal region (18) so that the emitter (13) is not underneath the emitter contact (19) in the region of the vertical emitter/base/collector sequence. The emitter terminal region (18) is transparent to light in the region of the vertical emitter/base/collector sequence and is also covered only by layers (21) permeable to light in this region, so that a direct irradiation of light into the active transistor region is possible. In particular, bipolar transistor structures which have been produced in a self- aligned manner in a double polysilicon process are suitable for use as phototransistors for detecting optical data rates in the Gbit/s region directly inside high-density silicon bipolar circuits. <IMAGE>

Abstract: In a magneto-optical disk for recording, reproduction or erasing with a laser beam, which comprises a film of four-layer structure consisting of a first dielectric layer (2), a magneto-optical recording layer (3), a second dielectric layer (4) and a metallic layer (5), laid on a disk substrate (1) provided with guide tracks, temperature distribution of the magneto-optical recording layer (3) is controlled by controlling the thermal diffusivity of the metallic layer (5), and recording/reproduction/erasing repetition characteristics are improved thereby. In the disk of the present structure, the temperature is elevated in a broader area from the center of laser beam, and thus a thoroughly broad erasing domain width taking a track offset into account can be obtained and not recording domains remain after the erasing. The reproduced signal output is increased by 4 dB, as compared with that obtained by a disk of three-layer structure without any metallic layer, because the beam utilization efficiency is increased owing to both Kerr effect and Faraday effect. When the disk of the present structure is subjected to field modulation recording, tails of arrow-feather-shaped recording domains peculiar to the field modulation recording can be shortened and interbit interferences can be overcome, resulting in an increase in C/N (S/N) ratio and the high density recording can be made. By endowing a Kerr enhancement action to the second dielectric layer (4) and a protective action on the magneto-optical layer (3) to the first dielectric layer (2), only the reliability can be improved without lowering the C/N ratio. By improving the corrosion resistance of the magneto-optical recording layer, the first dielectric layer (2) can be omitted to the contrary, and a magneto-optical disk of simple structure can be obtained and used as memory for domestic applications or communication fields.

Abstract: A truth-valued-flow processing unit according to the invention includes a truth value generator circuit array (11), a truth-valued-flow inference unit array (12), and a truth value converter (13). The truth value generator circuit array includes truth value generator circuits (TG1 - TG3) the number of which is the same as the number of kinds of input variables. Each truth value generator circuit generates truth values, which correspond to an applied input variable, with regard to a plurality of predetermined functions used by the antecedent of implications. The truth-valued-flow inference unit array includes truth-value-flow inference units (TVFI1 - TVFI7) the number of which is the same as the number of predetermined functions used by the consequent of implications. Each truth-valued-flow inference unit corresponds to each function used by the consequent. All truth values outputted by the truth value generator circuit array enter each of the truth-­valued-flow inference units. Each truth-valued-flow inference unit selects input truth values in accordance with predetermined rules and subjects these truth values to a prescribed operation, thereby generating a truth value that is to act upon the corresponding consequent. The truth value converter provides an output representing inferential results by applying, to the plurality of functions used by the consequents, the truth values outputted by the truth-valued-flow   inference units in correspondence with these functions.

Abstract: A weapon simulator, particularly for simulating small arms, comprises a laser projector (10) for attachment to the weapon (12). Firing the weapon (12) initiates the production of a narrow, pulsed, beam (14) by the laser, and this beam (14) is scanned vertically downwardly while its PRF is varied as a function of scan angle. The weapon/ammunition type can also be encoded in the laser pulses. The beam (14) is received by a spatially diverse pair of detectors on the target, typically comprising a first detector having an annular entry aperture covering about 6 cm in the vertical direction, and a second detector disposed in the centre of the annular entry aperture of the first. The central detector effectively determines the width of the beam, thus permitting the range from the weapon to the target to be computed from the beam width and the difference in the PRF detected at the start and finish of the illumination of the first detector. The elevation angle of the weapon with respect to the target is computed from the mean PRF detected by the central detector. Finally, the accuracy of aim of the weapon (ie whether the firing resulted in a hit or a miss) is determined from a combination of the range, the weapon elevation angle, and the weapon/ammunition type.
