Patent DE-3724343-A1 (DE)
Title: Display for impermissible operating states, especially in the case of domestic appliances
Inventor: HENNINGER ALFRED DIPL ING
IPC: D06F34/32
Filed: 1987-07-23
Abstract: Instances of defects must be displayed exactly and permanently. Known defect displays have an additional two-pole temperature regulator which is adjusted to a higher level. In the absence of the operating regulator, this connects a display means to voltage. The second contact takes over control of the apparatus after a time delay. The duration for which the display is switched on is a function of the switching difference of the second temperature regulator, and the response of the display means is a function of the switching accuracy of both regulators. The new display precludes switching inaccuracies and signals instances of defects permanently. Two heating resistors (R1, R2) are thermally coupled to a temperature-dependent resistor (NTC theta ) which has a high impedance in the cold state. A voltage is connected to the glow lamp (H), said voltage being below the triggering limit of said glow lamp. If (f10) opens, (R1) heats the (NTC theta ) whose impedance becomes low. The voltage at (H) rises and (H) triggers. If (f10) closes, (R2) heats the (NTC theta ). The display status is maintained. Brief opening (f10) does not cause the display to trip. The display is suitable for use as a fluff-warning display in the case of washer driers and as a scaling-up display for coffee machines. <IMAGE>

The invention consists in the semiconductor wafer used for fabricating the resistor having a defined thickness and a defined first and second doping, the first doping establishing the conductivity type and the second doping very largely compensating for the temperature coefficient of the resistance of the semiconductor wafer, and in the resistor being fabricated by dividing this wafer into resistor elements, the magnitude of the resistance being selected in such a way, by appropriate choice of the base area of the resistor element, that subsequent trimming of the resistor can be dispensed with.
Patent DE-3738267-A1 (DE)
Title: Microwave oven
Inventor: HOLTDIRK HANS-GERD DIPL ING
IPC: H05B6/76
Filed: 1987-11-11
Abstract: A microwave oven has a circulating air blower whose shaft can be guided through a metal muffle wall, and the microwave energy shall be prevented from leaving the oven space. The microwave traps already known prevent the microwave energy from escaping, but they require a higher outlay in terms of production. The novel arrangement of a microwave sealing is intended to prevent microwave energy from escaping the oven space without considerable outlay in terms of production. The short-circuit stub (2) is fastened on the back wall (1) of the oven muffle in the region of the passage opening (3) for a blower motor shaft (4). A resilient element (14) ensures the metallic contact between the short-circuit stub (2) and the motor support (7).   In the region of the bearing (8) there is a metallic connection between the blower motor shaft (4) and the motor support (7). The blower motor shaft (4) protruding out of the oven muffle is thus in metallic connection (short circuit) with the back wall (1). The arrangement for preventing microwave energy from leaving the oven space is particularly suited for use in ovens or baking ovens which have an integrated microwave unit. <IMAGE>

Patent DE-3813514-A1 (DE)
Title: Device for determining the temperature of cyclically moving parts of motor vehicles
Inventor: WEISHAUPT WALTER
IPC: F16D66/00
Filed: 1988-04-22
Abstract: In a device for determining the temperature of cyclically moving parts of motor vehicles having a transmitter formed as a pyrometer and responding to the emitted radiation, the position of the transmitter and the shape of the part are matched to each other in such a way that the part, during its movement, exposes and covers again a reference point of known temperature to the fixed transmitter. Conclusions can thus be directly drawn as to the temperature of the part from the difference between the output signals of the transmitter for the part and for the reference point.

Patent DE-3820815-A1 (DE)
Inventor: BOECKER HEINRICH DIPL ING
IPC: D06F58/28
Filed: 1988-06-20
Abstract: In a drum dryer in which laundry circulates due to a rotation of the washing drum (1) which is operated conjointly with a process air blower (13) and through which hot process air flows, the laundry may be circulated in a first drying section in alternate directions or alternatively only in one direction in which the blower (13) operates at full load and be subjected to a flow of very hot process air in that one direction. As a consequence, the operator has the choice if large laundry articles (bed linen, tablecloth) are to be dried to prevent entanglement of the wash by alternating the direction of rotation of the drum while on the other hand, if small laundry articles are to be dried, to reduce the drying time and the energy consumption by using only one direction of rotation of the drum. <IMAGE>

Title: Rotary gate for molten materials, especially metal melts
Inventor: HORNUNG KARL-OTTO DR ING
IPC: B22D41/14
Filed: 1988-12-14
Abstract: The gate body (21), which is designed as a truncated cone, which is rotatable about the axis (20) in the stator (11), has a throughflow passage (24), the openings (26, 27) of which are offset on the lateral surface (25) in the direction of the axis (20) of rotation. In the stator (11), there is a recess (14, 15) starting from each of the two outer surfaces (12, 13) intersecting the axis (20) of rotation and, in the open position of the gate body (21), each of these recesses communicates with one of the openings (26, 27). As a result, the gate can be installed in a melt vessel (1) in such a way that a simple rotary drive (30, 34) on the outside without a complex metallic supporting structure is possible and favourable flow conditions and thermal conditions for self-opening outflow are obtained. It can be used, for example, as a regulable outlet gate on holding or melting furnaces for nonferrous, particularly aluminium, melts. <IMAGE>

Title: Myocardial probe for location and treatment of heart defects - has laser source, potential sensing electrode and light emitting cap capable of large area deep tissue therapy
Inventor: HESSEL STEFAN DR
IPC: A61B17/00
Filed: 1989-04-11
Abstract: A myocardial probe for the treatment of rhythmic irregularities within deep heart tissue employs a laser light source (14), a flexible transmission cable (4) sheathed by tube (2) and a metal electrode (12) with lead (26) for the measurement of electric potential. The laser beam (22) takes the form of a hollow cone and the central electrode (12) is thus isolated from its effect. The resultant divergence of the laser beam (22) is optically controlled by directing its transmission via a gas or air filled space (6) before its emergence from the denser medium of the transparent cap (8). ADVANTAGE - Capable of deeper penetration, can treat larger area of tissue per unit time. Does not require surgery involving heart-lung bridge. Enables increased accuracy of laser dosing as result of precise potential measurement before, during and after treatment. External dia. of probe within 1.5 mm.

Title: Tapering via prodn. esp. in multilevel circuits - by etching insulation layers with different etch rates
Inventor: WARTH MARTIN
IPC: H01L21/768
Filed: 1989-05-03
Abstract: (A) In the prodn. of contact vias with sloping sides in insulation layers, which are applied onto a semiconductor material and which consist of e.g. oxide, oxynitride or nitride, by isotropic or anisotropic plasma etching with a variable etch rate, at least two insulation layes (2, 3) with different etch rates are arranged so that the etch rates decrease in the direction towards the semiconductor material (II) and the via (6) diameter decreases with increasing etch depth. (B) Also claimed is a semiconductor chip (e.g. of silicon) with metal conductor levels separated by one or more superposed insulation layers in which vias can be etched, the novelty being the provision of at least two insulation layers (2, 3) which can be etched to form vias of dia. decreasing with increasing via depth. ADVANTAGE - The via shape gives good connection between different wiring levels without the need for an auxiliary layer (see EP-282820) which requires additional expensive  process steps for removal.  The smooth slope of the via sides allows good sidewall coverage with aluminium by vapour deposits or sputtering so that no critical edge breakage occurs at the via sides during circuit operation.

Filed: 1989-08-25
Abstract: 1. A voice-controlled archival system with a scanning device for entering documents into a mass storage device. 2.1 In the past, the applications have been investigated for which the keyboard can be replaced by a voice input device. For the archival system application, it is found quite clearly that the use of a voice input device is only possible for inputting control commands. For inputting the information characterising the content of the document, the keyboard or corresponding devices generating text data must still be used. 2.2 The voice-controlled archival system according to the invention, also called Arc-Voice system, for the first time makes it possible to utilise a voice recognition system for inputting the information characterising the content of the document. The voice recognition system exhibits, among other things, a speech processor. The speech processor is connected to a control device which contains an access device and carries out a plausibility check by means of the available "prior knowledge" during the command and/or word recognition process.   2.3 The Arc-Voice system is preferably used for archiving bulk documentation. <IMAGE>
