IPC: H04B14/04
Filed: 1985-08-16
Abstract: A method and apparatus for digitizing audio signals being generated from a plurality of parties (A,B) in order to provide audio communication between the parties with a minimum of interference. Each of the parties has an audio transmitter and receiver (38,58). The audio signals are converted (42) to a PCM companded signal for transmission to a rmote location, and there converted (46) to an eight-bit parallel signal. A preprogrammed ROM (48) is located at the remote location and has a plurality of inputs and outputs. Each of the eight-bit parallel signals from the individual parties are fed to the ROM which produces an eight-bit output signal representing the instantaneous sum of the eight-bit parallel signals being supplied to its inputs. The ROM output is converted to a serial-digital signal by a parallel-to-serial converter (50) for transmission over a single line (52) to another serial-to-parallel converter (54) prior to being fed through a DAC to the receiver (58).

Abstract: An improved step and repeat alignment and exposure system for printing an image of a reticle onto a semiconductive wafer. A projection lens, such as a unit magnification catadioptric lens, projects the reticle image onto the semiconductive wafer. The semiconductive wafer is supported on stage means, which stage means provide motion in the X, Y directions. Novel viewing port means supplement the projection lens to provide a direct view of a portion of the semiconductive wafer which portion has been illuminated by the projected reticle image. In one embodiment a viewing port is formed in the mirror of a catadioptric lens by way of either a physical aperture or transmissive coatings. Off axis viewing of images through the viewing port is provided to provide telecentric images. A novel microscope structure is employed with large aperture focusing lenses to permit the infinity corrected objectives to translate about the field of view of the viewing port means without the requirement that any utilization device also translate in unison. Means are also provided for calibrating the position of the stage with respect to the reticle. Included are stage reference means which image a stage reference mark into the image plane of the unit magnification catadioptric lens when said stage reference means are illuminated by the projected reticle image. Means are provided for determining offset values between the projected reticle image and the stage reference mark and for utilizing said offsets in controlling the position of the stage. A novel reticle alignment window array and alignment mark are disclosed which provide both direction and degree of misalignment information without the requirement of relative motion between the reticle and semiconductive wafer. Also employed is a subsystem which is responsive to the relative amounts of light being provided in the image of the alignment mark as a function of the proportion of the alignment mark being illuminated by the images of each of the alignment windows in the array so that a real-time alignment correction can be obtained.

Abstract: To avoid a punchthrough breakdown in the off state of thyristors, the base (1) must be so thick that an adequate gap is left between the space charge zone and the p-n junction situated opposite at the nominal blocking voltage. Contact regions (15, 9) which extract the charge carriers produced under blocking conditions are situated on the anode and cathode side of the base in the vicinity of the anode-side emitter zone (2) and the cathode-side base zone (3). This allows the space charge zone to move nearer the p-n junction without there being a risk of punchthrough breakdown. …<IMAGE>…

Abstract: A control switch for remote-controlling a motor-driven automotive mirror. The stationary contact to be connected to one of the terminals of the motor to move the mirror about a vertical axis, the stationary contact to be con­nected to one of the terminals of the motor to move the mirror about a horizontal axis, and the stationary contact to be connected to the other terminal of the above two motors in common are formed on a circuit board. The bridge members to connect stationary contacts to the negative polarity of a power supply at thier ordinary position and to the positive polarity at their actuated position are accomodated in an enclosure fixedly attached to the circuit board. The actuating rods to act on the bridge members are arranged in the enclosure to be independent of one another, and one end of each of the actuating rods is projecting outside from the enclosure. The projecting ends of the actuating rods are related to the four mirror-moving-direc­tion-indicating portions of a push-plate, and as one of the direction-indicating portions of the push-plate is depress­ed, the related actuating rods cause the bridge members to act for a switching operation.

Abstract: An impurity detector (10) atomises a liquid sample by injecting it into a chamber (11) with a gas. In the chamber (11) the liquid is heated, preferably by heating the gas prior to injection, to cause all the liquid to evaporate. The solid impurities contained in the liquid are thus entrained in the gas and carried to a detector region (17). The chamber is arranged so that all the gas and all the particles arrive at the detector region (17). A particle detector (19) measures the number and size of the particles and from that measurement, the concentration of impurities in the sample can be determined. A first measurement is made with the liquid being fed directly to the impurity detector (10), and then a second measurement is made with the liquid being filtered by a filter unit (64) prior to being fed to the impurity detector (10). This permits two separate measurements to be made, and thus calculation of the amounts of soluble and granular impurities present. The system permits on-line operation, and produces accurate results.

Abstract: Hydrolysis of olefin oxides to their corresponding glycols is catalyzed by a steam stable zeolite, in its acid form, characterized by a constraint index within the range of about 1 to 12. Conversions of the olefin oxide, in the presence of water, proceeded with minimal catalyst degradation. The acidity of the zeolite enables the use of milder conditions than generally applied for this hydrolysis with no loss of desired selectivity. In addition, the described procedure offers the advantages such as ease of separation and use of fixed bed reactor.

Abstract: An improved virtual memory computer system (10) includes a main processing unit (12) which executes application programs. A dedicated second processing unit (20) is provided for maintaining a memory map, which translates addresses in the main processing unit address space into physical memory addresses of a primary memory (15). A network interface allows pages or segments of data from a secondary memory (27) connected to a communications network (25) to be transferred into the primary memory in a manner transparent to the operation of the main processing unit. Direct memory access means (DMA) transfer the header portion of a network-­transferred page of data into a separate auxiliary addressable memory for storage of network overhead information, while the useful data portions of the page are stored directly in locations in the primary addressable memory. A requested page of data is then placed directly in a desired location in primary memory without the need for moving or retransferring the data within the primary memory to strip off network header information, after a DMA transfer. The system is responsive to detect and correct a page fault condition prior to execution of the main processing unit instruction which generated the page fault, which obviates reexecution of instructions or correction of instruction execution results by the main processing unit.

Abstract: Monitoring a room is accomplished by measurement of air pressure where air passage resistance between a secured room and an outside atmosphere is measured and an alarm actuated, if the air passage resistance drops below a predetermined value. Evaluation of typical air pressure fluctuations in a frequency range between 0.01 Hz and 10 Hz is advantageous. The air pressure resistance may be determined by difference measurements of air pressure fluctuations in the outside atmosphere and the secured room, or as a singular process wherein a connecting tube is provided between the room to be secured and the outside atmosphere, where air movements varying as a function of air pressure fluctuations are measured. Devices for the carrying out of the process are described. The devices and the process provide a simple and cost effective alarm system that operates reliably and is secure against outwitting and sabotage.

Abstract: The edge masking layers (11a, 11b) (2nd spacer) consisting of silicon are produced after structuring the gate electrodes (7, 8) by depositing a silicon layer from the gas phase over the entire surface on the gates (7, 8) and source/drain diffusion regions (13, 14) previously covered with an oxide layer (16, 17, 18) and back-etching the silicon layer down to the silicon etching residues (11a, 11b) left at the edges of the gate structures (7, 8). These silicon spacers (11a, 11b) have the advantage over the known oxide spacers that no thinning of the field oxide (3) and no damage to the silicon substrate (1, 4, 5, 9) occurs during their production. According to the teaching of the invention, the process provides the possibility of establishing the channel lengths and the source/drain diffusion profiles of the n- and p-channel transistors independently of one another in the production of CMOS circuits by removing the silicon spacer (11a, 11b) after the n<+> implantation (13) and thus using the spacer (11a, 11b) only for the n-channel transistors.

Abstract: In the lampshade, ribs 3 are woven with weaving strips 6, 7 and joined by a stiffening ring-shaped part 5. The aim is to increase the transparency of the lampshade to light. This is achieved in that seen transversely to the shade the ribs 3 are in each case narrow like a board and by means of the ring-shaped part 5 which, receiving in a recess 4, is secured against tilting about its own longitudinal axis. The light coming from an incandescent lamp in the interior of the lampshade is hindered by the ribs only to a very slight extent on passing through the shade, since seen in the direction of passage of light the ribs are kept narrow or thin. <IMAGE>
