Abstract: 1. A method of converting digital input signals of a light waveguide transmission system from a first binary code comprising 32 different code words each comprising five binary digits corresponding to 32 possible amplitude values into output signals which occur in a second binary code comprising code values comprising six binary digits having a positive and a negative mode, where the mode corresponding to the continuous digital sum occurs at the end of the preceding code word comprising binary digits, wherein the 32 possible amplitude values (0...31) of the input signal are sub-divided into two equal sized sections each comprising 16 code words where the first section comprises the amplitudes values between a lowest amplitude value (0) and a first middle amplitude value (15) and the second section comprises the amplitude values between a second middle amplitude value (16) and a maximum amplitude value (31), wherein the code words for the positive mode of the output signal of the first section are selected to be such that the greatest possible conformity occurs between the input and output signals, and wherein for the lowest amplitude value of the second section the code word (49) for the positive mode corresponds to the inverted code word (14) of the negative mode of the highest amplitude value of the first section, and the code word (49) for the negative mode corresponds to the inverted code word (14) of the positive mode of the highest amplitude value of the first section, characterised in that for the second lowest amplitude value of the second section, the code word (57) for the positive mode corresponds to the inverted code word (6) of the negative mode of the second highest amplitude value of the first section, and the code word (17) for the negative mode corresponds to the inverted code word (46) of the positive mode of the second highest amplitude value of the first section, that the code words for the other amplitude values of the second section are formed correspondingly, and for the highest amplitude value of the second section, the code word for the positive mode corresponds to the inverted code word of the negative mode of the lowest amplitude value of the first section and the code word for the negative mode corresponds to the inverted code word of the positive mode of the lowest amplitude value of the first section, so that a diagonally inverted symmetry occurs between the two sections of the amplitude values of the input signal and the output signal.

Abstract: In a process of image recording by scanning a recording material (5) with a laser beam modulated by an image signal (S), the density of the recorded image is adjusted by controlling the light intensity during a predetermined interval using a clock pulse for picture elements, recording an image for a predetermined time within the predetermined interval, and changing the predetermined recording time for the entire image or only portions thereof. The recording time is changed in a very simple manner, for example, by operating a variable resistor (R).

IPC: G11C19/08
Filed: 1981-12-24
Abstract: A method of exposure used to form circuit patterns of a circuit chip of, for example, a magnetic bubble memory device or a semiconductor IC device whose circuit patterns are composed of a plurality of partially different circuit patterns. In this method, a plurality of projections of a single reticle is effected on a substrate as the substrate is moved by predetermined pitch lengths, and it is possible to form alternate circuit patterns which differ slightly, by arranging small external areas (45, 46) of the pattern to overlap with corresponding areas (43,42) within the main circuit pattern (44) by successive exposures with the same reticle but with alternating pitches of slightly different values.

Abstract: A portable electric drill has a printed circuit board assembly (40) mounted in a motor compartment (2) and attached to a stator lamination stack (38). A motor reversing switch (50) is mounted on the printed circuit board assembly (40) and has an operating pin (52) which cooperates with an actuating lever (12) that is mechanically interrelated to a trigger-switch (8) for energizing the drill. The trigger-switch remains inoperative until the actuating lever (12) is positioned to allow the motor (6) to be energized to drivingly rotate in either one or other rotational direction. The printed circuit board assembly (40) also has mounted thereon brush holders (44), noise suppression elements (122, 124), brush terminals (48), and field coil terminals (114, 116, 118, and 120). The pivoted lever (12) for operating the reversing switch pin (52) may be disposed inside or outside the motor compartment (2). The arrangement of the reversing switch (50) as a discrete integral component of the printed-circuit board assembly (40) reduces the required wiring between the handle and motor compartment and simplifies overall assembly of the tool.

Abstract: An ignition system for an internal combustion engine that provides automatically advanced timing over a predetermined range of engine speeds. The ignition system includes a timing circuit (100) that controls the resistance and hence voltage across a capacitor (53) that biases a switch in the trigger circuit (50) of the system. The transistor (125) is operated in its active region so that the transistor (125) operates as a variable resistor. As the resistance of the transistor (125) decreases with increasing engine speed the timing of the system advances. The predetermined speed at which the advance begins is determined by zener diode (119) in series with the base of the transistor (125). The maximum advance of the system is limited by a resistor (94) in series between the transistor (125) and the capacitor (53) of the trigger circuit (50). The transistor (125) is operated in its active region by a transistorized circuit that receives its power from the main storage capacitor (27) of the ignition system.

Abstract: Disclosed is an electron gun comprising a cathode, a first apertured anode spaced from said cathode and operated at a potential of between 5 and 30 volts positive with respect to the cathode. The gun further comprises a second apertured anode spaced from the first anode and operating at a potential of between 100 and 400 volts positive with respect to the cathode to produce a lens field in the region between the anodes which focusses the electrons emitted from the cathode at a crossover therebetween. The cross-section of the beam produced by the gun is determined by the size of the aperture in the second anode and the beam current may be varied by changing the voltage on the first anode to thereby move the crossover closer to or further away from the second anode so that a larger or smaller portion, respectively, of the electrons in the beam passes through the aperture. 
     Alternatively, a beam-limiting element, separate from the second anode, may be used.

Abstract: An improved gasifier and method for production of combustible gases from biomass fuels are disclosed in which a massive refractory layer has a first inclined fuel supporting surface or ramp. Massive refractory is provided above and opposing the first fuel supporting surface within a primary gasification chamber. Another mass of refractory cooperates with the first inclined fuel supporting surface of the massive refractory ramp to provide an air seal upon fuel delivery and thereby avoid the disadvantageous introduction of air into the pyrolysis zone of the gasifier. During gasifier operation, massive refractory heats to high temperature. Biomass fuel delivered to a carbonization zone releases volatile gases by virtue of heat radiation from the massive refractory, and as a consequence of the reflection of heat generated in the combustion zone from massive refractory surfaces within the primary chamber. Additionally, the gasifier includes a lower refractory layer having a second inclined surface or ramp. In a preferred embodiment, the second surface has a plurality of air inlet holes therethrough to provide air distribution only in a specific and concentrated combustion zone located below the carbonization zone. The lower refractory layer second inclined surface is appropriately inclined at an angle of inclination or steepness greater than the first fuel supporting surface of the massive refractory layer to provide for continuous and smooth flow of biomass fuel through respective zones of the gasification chamber.
