Abstract: A method for manufacturing an intraocular lens 10 from a cell cast sheet of high molecular weight polymethylmethracrylate (PMMA). A lens blank 30 having a lens generation area 31 with a surface contoured to correspond to the desired contour of the finished lens 10 is machined from the sheet of PMMA to a predetermined precompensated size larger than desired to accommodate normalizing shrinkage. The lens blank 30 is normalized by heating the blank in a vacuum oven. The vacuum is released from the oven by introducing dry nitrogen. A stamping die 54 is provided. An optical embossing surface 56 of the stamping die is contoured as a physical negative of the lens generation area 31 and bears a physical negative of the desired optical surface structure of the lens, such as a multifocal diffractive zone plate 18. The embossing surface 56 of the stamping die 54 is forced into engagement with the surface of the lens blank 30 at a predetermined stamping pressure and for a predetermined stamping dwell time. Sufficient heat or ultrasonic energy is applied to the lens generation area 31 of the lens blank 30 to heat the lens generation area to a temperature between the glass transition temperature and the melt temperature of the polymer, and emboss the surface structure onto the lens generation area. The embossing surface 56 of the stamping die 54 is removed from the lens blank 30 following the expiration of the stamping dwell time.

Abstract: An analog to digital (A/D) conversion system (10 or 20) receives a modulated analog signal, translates the frequency of the signal to a lower frequency, and converts the analog signal to a filtered digital signal. In one form, the conversion system (10) has an analog signal multiplier (16), an A/D converter (18), an oscillator (12), and a frequency divider (14). Frequency multiplier (16) translates the frequency of the analog signal, and A/D converter (18) converts the analog signal to digital form. Frequency divider (14) receives a clock signal from oscillator (12) and divides the frequency of the clock signal. Because the same clock signal is used for frequency translation and analog to digital conversion, a phase error is not introduced in the output digital signal. Additionally, the frequency divider (14) forces the frequencies of the analog and digital signals to be an integer ratio for subsequent demodulation.

Abstract: A CDMA cellular radio-telephone system has switching systems (201) synchronized to public telephone network (100) timing signals and radio telephones (203) and cell base stations (202) synchronized to a different clock. Transmission delays between the cell base stations and the telephone network are variable. Switching systems include digital communications interfaces to the telephone system, whose connections to the telephone system are synchronized to the telephone system, and whose connections to the cells art nominally also synchronized to the telephone system but whose processor operates for each call within predefined windows of phase relationships to the operation of the cell that is handling the call, and occasionally adjusts its phase relationships to the operation of the telephone system to achieve and maintain its operation within the predefined windows. Packet-switched communications between the cells and the switching systems absorb the phase relationship fluctuations and the timing adjustments in inter-packet intervals. Circuit-switched digital communications between the switching systems and the telephone system absorb the timing adjustments by means of vocoder implemented slips --bit insertions or deletions-- in the communications traffic bit stream.

Abstract: A method for attenuating optical crosstalk induced components of a focus error signal in an optical disk drive of the type having a grooved optical disk with servo tracks and tracking and focus servo systems controlled by a digital signal processor. A calibration operation is performed whenever a new disk is inserted into the track. During the calibration operation, the disk is scanned about a tracking axis at a track crossing frequency greater than the focus servo system bandwidth. The focus error signals produced when the disk is scanned are filtered about a pass band including the track crossing frequency. Crosstalk values equal to values of the filtered focus error signals are determined as a function of corresponding values of the tracking error signals, and are stored in memory. A correction operation is performed while reading and writing data on the disk. During the correction operation, the crosstalk values are read from memory as a function of corresponding values of the tracking error signals, and summed with the focus error signals.

Abstract: In a blow molding machine, a mold for clamping a parison is arranged below an extruder (10) extruding the parison; the parison (2) is cut above the upper surface of the mold (8, 8') so as to leave an upper flash on a molded article. The blow molding machine is operative to perform an article removing process, in which the configuration of the upper end of the parison is corrected into a flat and vertically extending configuration before solidification so as to facilitate clamping of the upper flash of the article by an article removing device (80). The blow molding machine is also provided a capability of performing quality discrimination for discriminating a normal article and a defective article during a process between a stage of initiation of extrusion of the parison and a stage of removing the article so as to discharge the removed article to a normal article discharging destination (301) for a normal article and to a defective article discharging destination (303) for a defective article on the basis of the result of the quality discrimination. The blow molding machine (1) may also have a capability of deriving a relationship between a parison length of a resin to be used and a screw rotation speed of the extruder depending upon the resin to be used, and controlling the extruder screw rotation speed by calculating a correction amount for the extruder screw rotation speed according to the determined relationship between the parison length and the extruder screw rotation speed to attain the target parison length.

Abstract: So that biologically degradable components of waste, for example domestic waste, can be degraded directly at the point of occurrence within a useful period, it is proposed to use compost worms together with microorganisms in a rotatable drum (1). The drum (1) is preferably mounted on rollers (3). It is divided by a perforated partition (4C) into two chambers 4/I and 4/II of equal size and the drum floors (4B) are provided in each case with a ventilation aperture (4B1) covered with a fine netting material and in each case with a lockable folding door (4B2). Before loading, the drum (4) is rotated several times and loaded with waste (2) in a chamber-by-chamber fashion in such a way that the chambers (4/I, 4/II) are filled with waste (2) one after the other. To degrade the waste (2) into compost (2') the biomass migrates from one chamber (4/I) to the other chamber (4/II), depending on where the nutrients are to be found. To start the process, the use of microorganisms and compost worms in a durable ready-made form is proposed. <IMAGE>
