Title: Washing machine or the like having a weight indicator for filled-in material to be washed
Inventor: SCHUCHARD SIGLINDE DIPL ING
IPC: D06F34/18
Filed: 1988-02-13
Abstract: It is known to equip washing machines with mechanical-electrical convertors and electrical measuring devices for indicating the weight of filled-in material to be washed. Such measuring arrangements are costly to manufacture and can be susceptible to faults. The weight indicator has markings (12, 13, 14) for the filling height (15) of material (11) to be washed. By this means, the weight of filled-in material (11) to be washed is indicated simply, reliably and with sufficient accuracy via the filling height (15) of the material (11) to be washed. The weight indicator can be used in washing machines, washer-driers and driers. <IMAGE>

Patent DE-3811946-A1 (DE)
Title: Electrical flowmeter
Inventor: FLEIG HEINZ
IPC: G01F15/075
Filed: 1988-04-11
Abstract: The invention relates to a flowmeter, especially according to the magneto-inductive principle or the impeller principle. Assigned to the measuring device is a monitoring device which sums the measured flow at the place of installation of the flowmeter over a time period, e.g. days, weeks, months, which is determined by a presettable time switching device, calculates an application-characteristic average value of the flow from this sum and fixes it in a store. The flow in the flowmeter is then monitored by means of the monitoring device for a particular overshoot of the fixed average value. If the deviation in the average value of the flow overshoots a limiting value provided by a first numerical ratio (factor 1), an indicator on the flowmeter is then activated. If the deviation also overshoots a limiting value provided by a second numerical ratio (factor 2), a report is directed to a control centre.

IPC: E21C27/34
Filed: 1988-08-20
Abstract: The invention relates to a baseplate plough with a multi-piece baseplate, preferably a three-piece baseplate, reaching under the face conveyor. The baseplate parts (2, 3, 4) are connected on the face side in a tension-proof and pivotable manner, preferably via pivot joints (7), and are attached on the goaf side by means of coupling extensions (14, 15, 16) to chain blocks (17, 18), to which the plough chain (22) is connected. According to the invention, the adjacent baseplate parts are attached with their coupling extensions (14, 15) to a common chain block (17) with axial clearance of motion, as a result of which the centring and alignment of the baseplate parts is improved. On the goaf side near their coupling extensions, the baseplate parts (2, 3, 4) have end faces, serving as pressure surfaces (24, 25) and preferably crowned, for the transmission of the chain pulling forces. The chain blocks (17, 18) are conveniently an integral part of chain gear included in the plough chain (22). The axial play of the coupling extensions in the chain blocks is preferably made in such a way that the plough is pushed by the driven plough chain. <IMAGE>

Title: Optical data store with a date storage disk formatted for positioning
Inventor: SPENGLER WERNER DR RER NAT
IPC: G11B7/007
Filed: 1988-09-30
Abstract: Arranged on the data storage disk (6), alternating in track direction, are data sectors (63) and servo sectors (62). The servo sectors are formed without track grooves and, for deriving track error signals (PES), contain next to one another in the track direction a first and a second pair of information fields (A, B and C, D) for one marking element (65) each. The marking elements (65) in the two pairs of fields are arranged radially offset by one track interval (TW) with respect to one another. In the first pair of information fields (A, B) the marking elements lie symmetrically with respect to the track centre, in the second pair of information fields (C, D) the marking elements are offset thereto by half a track interval, impressed on a level with the track centres. This servo pattern makes it possible to compose the position error signal from sectionally linear curves of the same slope in terms of the absolute amount and the operational sign, which increases the control stability in positioning operations. This is of advantage in particular in the case of optical data stores with random access. <IMAGE>

Title: Bipolar high-frequency transistor and method for producing the transistor using the polysilicon self-alignment technique
Inventor: NIHIRA HIROYUKI
IPC: H01L21/308
Filed: 1989-05-12
Abstract: In the case of a bipolar transistor having a microminiaturised structure for high-frequency LSI, which is produced by using a self-alignment technique, an insulating barrier film (115) is buried in a section around an emitter layer (121) in such a way that it is deeper than the level of the transition region between an active base layer (118) and a collector layer (103). When the structure (pattern) of a polysilicon film (110) which defines an active base region and is used as a section of a base electrode is formed on the surface of the semiconductor wafer, a surface section of a photosensitive resist (111) used as an etching mask is converted by ion implantation into a carbonised layer. If a microminiaturised emitter layer is produced by a polysilicon-emitter technique, ion implantation is carried out before the polysilicon film is applied or an impurity is doped into the polysilicon film simultaneously with the deposition and fast thermal annealing is carried out in order to activate the impurity doped in (Fig. 7A to 7H). <IMAGE>
