Abstract: A device for movable parts for closing openings in motor vehicles, having a reversible DC drive motor, a polarity reversing actuation switch located in the motor circuit for supplying a DC voltage to the motor circuit with a poling corresponding to the desired direction of rotation of the motor, a relay with a switch contact located in the motor circuit in series with the polarity reversing actuation switch, as well as a position detection stage, connected to the relay control circuit, for actuating the relay in a reference position of the movable part for the purpose of deactivating the drive motor by opening the switch contact. The relay is a DC relay which opens or closes the switch contact when a first or second voltage level is applied to its control circuit. An electronic relay actuation stage with storage behaviour is connected to the relay control circuit. The relay actuation stage is kept in the set state as a function of the position of the movable part when the polarity reversing actuation switch is closed until the movable part has left the reference position (Fig. 1).

Abstract: When low-level data is output from a data output terminal (T1), a plurality of transistors (12A, 12B), whose source-drain paths are inserted in parallel between the data output terminal (T1) and a power source terminal (T3), begin to conduct at successively different time-points. Thus, the potential fluctuations produced on the ground voltage side (V SS  side) and power pource voltage side (V DD ) side by the parasitic resistive and inductive components present on the current are dispersed over time, avoiding circuit component malfunction. Further reduction in noise can be achieved by making the gate drive voltage (N2) of the first transistor (12A) which conducts in a switching cycle when low-level data is output, smaller than that of the remaining transistors in the switching cycle, so that its current when coducting becomes smaller.

Abstract: A binding element for perforated sheets of the type comprising a length of wire bent so as to form curved prongs on which the sheets may be impaled, the wire being in the shape of a flat comb, the prongs of which are closed at their tips and opened at their bases or roots which are connected to their neighbours by aligned lengths of wire forming the stock or the spine of the comb, the strip being designed to be converted to a slotted tube by suitable bending of the prongs. In accordance with the invention the concave surface with part of each prong which is midway between its tip and root is formed with an indentation, which indentation assists the closing of the binding element very effectively and without any visible sign.

Abstract: A method of forming a glass sheet with ceramic paint thereon is disclosed. The method has the following general steps. A first ceramic paint (12) is applied to and dried on a glass sheet (10). The first ceramic paint includes a low temperature melting glass frit as a component thereof. A second ceramic paint (16) is applied over at least a portion of the dried first ceramic paint. The second ceramic paint includes as a component thereof a high temperature melting glass frit. The high temperature melting glass frit melts at a temperature higher than that temperature at which the low temperature melting glass frit melts at. In another embodiment a single layer of ceramic paint is applied to the glass sheet, said paint including a high temperature melting glass frit and a low temperature melting glass frit. The glass sheet is heated to a temperature which softens the glass sheet sufficiently so that the glass sheet can be formed. The heated glass sheet is engaged by a fiberglass covered forming die to form the glass sheet into a desired shape. The formed glass sheet is removed from the forming die, the second ceramic paint being effective to prevent sticking of any ceramic paint to the fiberglass covered forming die.

Abstract: The present invention is concerned with a method for modulating and recording data, in which the data are modulated in such a manner that m-bit data are converted into n-bit data, where m and n are real integers and m < n, p-bit merging bits are inserted between the n-bit data and the number of consecutive "0"s in the alternate concatenation of these n-bit data and p-bit merging bits is not less than a predetermined number  d  and not more than a number  k  which is larger than  d , wherein the merging bits of the bit pattern consistent with a digital sum value (DSV) of recording data are inserted between the n-bit data and the DSV is reset at each data block as one unit to facilitate data control for each data block as a unit. The present invention also provides a data recording medium (51) on which are recorded data following this method. When the recording data are demodulated and reproduced from the recording medium (51), it is decided whether the bit pattern of the above merging bit is consistent with the modulation rule and the error detection data which deem the reproduced data in the vicinity of the merging bits not consistent with the modulation rule as being in error are outputted along with the reproduced data to improve the reliability of the reproduced data produced in the reproducing system.

Abstract: The invention relates to a method of making tubular construction parts, a tube being formed starting from a sheet and the two ends being welded to one another and the tube thus obtained being subjected to an expanding process. The object of the invention is to provide a method of making tubular construction parts with which high-quality tubular construction parts, for example for baking tubes, can be made in a cost-effective and operationally reliable manner. The invention essentially consists in the tube being mechanically pre-expanded before the expanding process and in the pre-expanded tube, with its two ends sealed, being subjected in a closed manner to a hydroforming expanding process. The advantages achieved consist in particular in the fact that, when the method is used, there is a considerable saving of material with regard to the body to be made and virtually no scrap arises in the course of the manufacturing process. Furthermore, low tool costs result for the changeover if various types of tubular construction parts are made. There is also no problem in using sheets of the most varied quality, e.g. normal deep-drawing steel as well as austenitic and ferritic stainless steel. Different sheet thicknesses can also be readily processed. <IMAGE>

Abstract: There is disclosed a high-speed decoding apparatus for use in a flash-type analog-to-digital converter. The apparatus disclosed employs an OR gate (70) which follows an AND gate (53), which AND gate is conventionally employed in a comparator associated with such a converter. The OR gate functions to block any dynamic movement of the unknown input voltage from being transferred to the decode lines of the analog-to-digital converter. To further gain speed, autozeroed inverters (74, 75; 77, 78) are coupled to the output of the OR gate to further assure that the decoder lines are rapidly driven to therefore gain an extra advantage in high-speed operation of the converter employing the apparatus as described.
