Title: Device for digital measurement of the change in physical variables
Inventor: JAHNS JUERGEN DR
IPC: G01S7/497
Filed: 1988-06-27
Abstract: The device according to the invention determines length or separation changes which are caused by changes in physical variables such as temperature and pressure, by means of propagation time measurement (delay time measurement) of electrical signals in an optical waveguide (LWL) which is subjected to the physical variable. Signals are fed into the optical waveguide via an optical multivibrator (S, SE, E, EA). In this case, the total propagation time of a plurality of pulses is determined via a high-frequency counter. The deviation of the actually determined counter result from a normal counter result is determined by comparison with said normal counter result, this deviation is used to determine the length or separation distance which has occurred, and this length or separation difference is converted into the physical variable to be determined. The device requires only a small number of cost-effective and proven components and permits highly accurate determination of the physical variables to be evaluated. <IMAGE>

Title: Winding apparatus
Inventor: RUNKEL WALTER DR ING
IPC: B65H54/52
Filed: 1988-07-06
Abstract: In the state of the art attempts are made to control the pressing force achieved by spin effect between a winding bobbin and driving roller of a winding apparatus in the desired way by means of complicated cam guides or slotted guides. The new apparatus is to achieve the control of the pressing force between the bobbin and driving roller during the winding run by simple means. This is achieved by the use of a plurality of, for example two springs having different spring characteristics. Because the abutments on the machine frame and the suspensions on the body lever are arranged in an appropriately different manner, it is possible, by the addition of the, for example, two spring characteristics, to achieve the desired trend of the common spring characteristic. As a result of the combination of the spring effects, it can be ensured, for example, that the pressing force remains essentially constant during the winding run.

Patent DE-3827614-A1 (DE)
Title: Method for producing a semiconductor component
Inventor: LUTZ JOSEF
IPC: H01L21/22
Filed: 1988-08-13
Abstract: The semiconductor body of fast semiconductor components for high blocking ability can have mesa structure or planar structure. In order to optimise the switching performance, the small skin depth of the planar zone is favourable and the planar structure is therefore advantageous. However, the semiconductor oxide coating provided for passivation of the pn transition stores the heavy-metal atoms to be introduced for reducing the switching time. This coating therefore becomes ineffective and must be replaced by a new coating. With the method according to the invention, the passivation coating is not degraded by the introduction of heavy-metal atoms. According to the invention, before the introduction of the heavy-metal atoms, an additional layer of an inorganic insulating material is produced on the coating, and after the formation of the recombination centres, the additional layer is removed again. A compound of or with semiconductor material is preferred as the insulating material, especially phosphor glass or semiconductor nitride. The thickness of the additional layer lies in the range of up to 25  mu m. Use in power electronics components and circuits.

Patent DE-3901786-A1 (DE)
Title: Modulo-10 counter
Inventor: MERKLE PAUL
IPC: H03K23/50
Filed: 1989-01-21
Abstract: The modulo-10 counter according to the subject of the invention consists of decades, each with nine counter flipflops (25), and a pulse reversing circuit (10), and is arranged so that on the tenth decade counter pulse not all counter flipflops (11 to 19) flip into their right position, but only counter flipflops (11 to 14 and 19). The remaining counter flipflops (15 to 18) flip into their right position on the next first decade counter pulse if flipflop (11) already flips back into its left position. This avoids at the same time having to flip nine counter flipflops simultaneously into their right position using one counter pulse. Special delay circuits, which each have a simple flipflop as their main part, are used as delay circuits (20a and 20b). Counter flipflops (12 to 19) are triggered via two pulse lines alternately by the outputs of the AND circuits (31 and 32). Counter flipflop (11) is triggered separately. <IMAGE>
