Abstract: An opto-electronic device has an atomic layer superlattice semiconductor comprising different semi­conductor materials periodically piled up, each material having an atomic layer thickness. The superlattice semiconductor has a bandgap different from an alloy semiconductor having equivalently the same composition as the former. 
     In a semiconductor laser, as clad layers (33, 35; 43, 45), the atomic layer superlattice semiconductor having equivalently the same composition as a Zn 0.42  Cd 0.58  S alloy semiconductor and a larger bandgap than the later is used, and a ZnSe 0.94  S 0.06  alloy semi­conductor as an active layer (34, 44) is located between the cladding layers. The double-hetero structure semi­conductor laser thus provided can perform the lasing at 470 nm at room temperature.

Abstract: A successive approximation type A/D converter of the present invention has a capacitor (C F ) having a pre­determined capacitance value and arranged between an input terminal of a voltage comparator (A, SW) and an fixed potential terminal having a predetermined poten­tial. According to the successive approximation type A/D converter of the present invention, the capacitor (C F ) arranged between the input terminal of the voltage comparator (A, SW) and the fixed potential terminal having the predetermined potential prevents a potential at the input node of the voltage comparator (A, SW) from being greatly changed to exceed a power source voltage range due the influences of a local D/A converter (C1, C2, C3, C4, SL1, SL2, SL3, SL4, D) when the sample mode is switched to the approximation mode. Therefore, the leakage of charges stored in the input side of the volt­age comparator (A, SW) can be prevented. Accordingly, even if the amplitude of an analog input voltage is equal to the amplitude of the power source voltage, high-precision A/D conversion can still be performed.

Abstract: Bei der Pegeleinstellung von Audiosignalen mit Hilfe von C-MOS-Schaltern (IC1) (Multiplexern) entstehen während des Einstellvorgangs Knackgeräusche, die durch kapazitive Verkopplungen der digitalen Ansteuersignale in den Nutzsignalpfad einstreuen. Um diese Störgeräusche zu vermeiden, wird das Nutzsignal (Ue) dem Eingang eines gleichartig aufgebauten C-MOS-Schalters (IC2) zugeführt. Das Nutzsignal wird an diesen Eingang jedoch über einen Inverter (INV) gegenphasig gelegt. Die Ausgänge der beiden C-MOS-Schalter sind (IC1, IC2), gegebenenfalls über Verstärkerstufen (OP2, OP3), an je einen Eingang eines Differenzverstärkers (OP4) geschaltet. Am Ausgang dieses Differenzverstärkers entsteht ein von Knackgeräuschen freies Nutzsignal (Ua), da nur die Störgeräusche kompensiert werden. Die Erfindung wird insbesondere in Audioverstärkern verwendet.

Abstract: In a device for comminuting rock or the like by means of a propellant charge (8) and a liquid (10) placed in front of this, in order to utilise the energy of the propellant charge (8) essentially completely for comminution purposes, and furthermore to simplify the operation of the device, the latter has a tube (16) to be inserted into a drillhole (25) of the object (26) to be comminuted. Arranged on this tube (16) is a multi-part spreader sleeve (3) having an inner cone (2a) which interacts with an outer cone (2) on the tube (16) when the latter experiences a recoil after the ignition of the propellant charge (8). The spreader sleeve (3) is thereby pressed against the wall of the drillhole (25), thus assisting the comminuting effect of the liquid jet (15) issuing through the nozzle (4). At the same time, a bracing and retention of the device in the drillhole (25) are obtained by means of this spreader sleeve (3). The utilisation of the energy of the propellant charge (8) is further improved if the nozzle (4) is mounted axially displaceably in the tube (16) and has an outer cone (1) which interacts with an inner cone (1a) on the spreader sleeve (3). When, after ignition has occurred, the pressure of the liquid (10) displaces the nozzle (4) towards the end of the drillhole, the spreader sleeve (3) is pressed even more firmly against the wall of the drillhole (25) via the outer cone (1) and inner cone (1a). <IMAGE>

The tipping moment of the side bracket is introduced into the strut (3) with the aid of an opposing bearing edge (21), constructed on the side bracket (4). <IMAGE>

Abstract: A sinusoidal speech representation system is applied to the problem of speech dispersion. The sinusoidal system first estimates (16) and then removes (18) the natural phase dispersion in the frequency components of the speech signal. Artificial dispersion based on pulse compression techniques is then introduced with little change in speech quality. The new phase dispersion allo­cation serves to preprocess the waveform prior to dynamic range compression (20) and clipping (22), allowing considerably deeper thresholding than can be tolerated on the original waveform.

Abstract: An adjustable sheet cassette for use in apparatus feeding sheets such as in an automatic copier or printer comprises a sheet stack support platform (35) capable of supporting various stacks of sheets of a plurality of length and width dimensions, sheet width and length dimension representing members (42, 43) on the cassette, each independently movable by means of pins (53, 54) which engage in slots (51, 52) forming camming surfaces in bottom plates (49, 50). Movement of sheet edge guides (28, 29) secured to the bottom plates (49, 50) in order to accommodate a stack of sheets thus moves the dimension representing members to a plurality of positions representing a plurality of sheet width and length dimensions. The positions of the dimension representing members are detected by detectors on the main apparatus, and a controller determines the length and width dimensions of the copy sheets in the cassette thereby enabling the apparatus to automatically select the correct cassette to supply sheets for a printing operation. In a preferred embodiment the positions of the dimension representing members operate a set of switches to provide a binary code which represents the sheet length and width, the binary code being decoded by the controller.

Abstract: A spring retainer is disclosed for use in retaining fuel pellets in a fuel rod both during fabri­cation and shipment to prevent the fuel pellets from being moved from their design location before installa­tion within a reactor. The cylindrical and solid nuclear pellets (P) containing the reactor fuel are placed within the fuel rods (F) (or cladding) and have an outside diameter sightly less than the inside diameter of the fuel rod. Once the pellets are in place, a two-part spring holder (16, 18) is inserted into the end of the fuel rod. A first compression spring part (16) of the coil spring holder is a conventional coil spring which, acting in compression, bears against the fuel pellets with a pre­selected force typically forcing the pellets when in the horizontal position into a compacted disposition when the fuel rod is horizontal. This conventional coil spring has a diameter which is less than the inside diameter of the fuel rod. A second locking spring part (18) of the coil spring holder is a coil spring having a diameter which exceeds the inside diameter of the fuel rod. This helical locking spring is spirally wound down to an outside diameter less than that of the inside diameter of the fuel rod for insertion into the rod and released to key to the inside diameter of the rod. Winding occurs through a special tool which attaches to the respective ends of the coil spring. By winding one end of the locking coil spring relative to the other end of the locking coil spring, spiral wind­ing of the helical spring to a diameter less than the inside diameter of the rod occurs. Installation   includes winding the locking spring, inserting the wound locking spring, compressing the installed fuel pellets with the compression spring, and releasing the spirally wound helical locking spring to unwind the locking spring so that it keys to the inside walls of the fuel rods. The disclosed design accommodates con­ventional fuel getters and is shown with a preferred one piece construction where the compression and lock­ing spring sections are fabricated from the same single piece of wire.
