Patent DE-3242272-A1 (DE)
Inventor: MEIER GERD E A DR
IPC: H01Q9/28
Filed: 1982-11-15
Abstract: Wide spectrum directional antenna with at least one antenna wing (1). The antenna wing has a semi-heart shape in the longitudinal direction to obtain a simple construction form in the case of the largest possible spectrum width and relatively small variations of the input resistance in the field of the broadband of the antenna wing (1). The shape of the two antenna wings (1) as a double antenna is similar to the shape of a heart. The useful broadband frequency spectrum of this antenna extends uninterruptedly from a lower limit frequency of which the wavelength is substantially equal to the triple of the length L of the antenna. The input resistance is constant or decreases slightly and the antenna gain increases with the frequency up to arbitrarily high frequencies. The maximum broadcast direction of the double antenna coincides with the symmetry axis of heart-shaped radiation device and is turned away from the point of the heart forming the power supply (3) of the antenna wings.

Title: Catch device for a body composed of elastic material
Inventor: KIEFNER HERMANN
IPC: H01H19/11
Filed: 1983-03-23
Abstract: Catch devices are preferably used for joining plastic parts without screw connection. In this case, a catch hook formed at the free end of a resilient tongue is introduced into a receptacle, within or behind which the catch hook is anchored. The invention provides a solution which is simpler in terms of injection technology and improved in its application in that, for a body (21) composed of elastic material, it provides for the catch device a round or polygonal spring ring which is closed and is held via webs (22). Thickenings, projecting beyond the surface of the body (21), are moulded as catch hooks (26) onto the segments of a spring ring (23) located between two webs (22). The segments of the spring ring (23) located between two webs (22) are loaded both in terms of bending and in terms of torsion during engagement. <IMAGE>

Title: Thermoelectronic control loop for absolute radiation measurement and contactless temperature measurement
Inventor: LANGE LUDWIG DIPL PHYS
IPC: G05D23/19
Filed: 1983-07-08
Abstract: The invention relates to a thermoelectronic control system which feeds back in a self-regulating fashion to a receiving device acting as a controlled system, by virtue of the fact that a double PID controller continuously maintains constant temperature differences and thus constant thermal fluxes within the system, or that in the event of symmetry between the radiation absorber and reference body a PID controller sets the temperature difference between the two to zero. Via voltage-controlled current sources, the controllers simultaneously control internal compensating outputs whose difference is exclusively equivalent to the radiant power absorbed by the aperture of the cavity absorber. Because of the virtually inertialess, electronic control and the special control method, both thermal inertia in the receiving components and external interference are eliminated. This permits reliable radiation measurements without spectral selectivity from the longwave infrared up to the ultraviolet, even in the case of non-stationary energy flux densities. This includes a weighty advantage by contrast with the previously used metrological methods for absolute radiation measurement. The spectrum of application reaches from the absolute measurement of output of thermal radiators up to a few 1000 K, via the contactless monitoring of temperature changes, measurement of optical and thermal material properties as far as the control and regulation of technical installations and processes.

Patent DE-3343367-A1 (DE)
Inventor: PAMMER ERICH DR RER NAT
IPC: H01L23/48
Filed: 1983-11-30
Abstract: A semiconductor component having bump-like, metallic lead contacts and multilayer wiring wherein individual tracks of each and every electrical signal or potential to be wired in multilayer wiring technology are electrically connected to the respective lead contact in the region thereof and to one another, but are separated from one another in the remaining regions of the semiconductor component by insulating layers. The various insulating layers terminate at different distances from the lead contacts in such fashion that their ends, depending upon the embodiment, form a funnel that tapers either down or up. The difference of the respective distance of the ends of two neighboring insulating layers from the corresponding lead contacts amounts to at least twice the thickness of one of the two layers. Given different layer thicknesses, a dimension of the thicker layer is used. An insulating layer may be at most 2  mu m thick, and preferably 1  mu m. Edge interruptions at the tracks and sputtering gaps and voids at the lead contacts which lead to contact causticization, corrosion, and subsequent electrical failure are thus avoided.

Title: Card reader for terminals
Inventor: AWAKOWICZ ERWIN
IPC: G06K7/00
Filed: 1983-12-02
Abstract: Arrangement for connecting contact springs (3), connected to evaluation devices, to contact points (5) of a card (6) held in a movable receptacle (7) of a card reading device and provided with value units. A suitable device is intended to ensure that the electrical connection between the contact points (5) of the card (6) and the contact springs (3) is established only once the receptacle (7) is approximately in the final position. For this purpose, the contact springs (3) do not make contact with the contact points (5) of the card (6), by means of a device (2, 10) which moves them in a vertical direction, until the receptacle (7) is in the state for cancellation of the card. Undesirable dragging of the contact springs (3) over the card (6) when the receptacle (7) is removed or inserted, and the consequent damage to the contact surfaces, are prevented by means of this device. Card readers of this type can be used, for example, in telephone system devices. <IMAGE>

Title: Eccentric press with a pushing rod adjustment device
Inventor: JUNGINGER GEORG DIPL ING
IPC: B30B15/00
Filed: 1984-01-12
Abstract: The invention relates to an eccentric press with a pushing rod adjustment device. Such pushing rod adjustment devices are driven via a transmission system either manually or by means of a braking motor, the setting for the various tools being determined on an empirical basis, which is, however, a very unreliable and time-consuming method. According to the invention, an automatically operating pushing rod adjustment device is proposed with positioning which is sufficiently accurate, it being possible to predetermine the setting and carry out adjustment at the same time as other modifying actions. This is achieved according to the invention by combining the following characteristics:     a) pulse generator on the rapidly rotating drive shaft (21); b) entry into position in the same direction in principle, preferably in the weight-raising direction; c) determination of the brake path before each entry into position;   d) reference pulse inside the maximum adjustment path possible, evaluated in the same direction in principle, preferably in the weight-raising direction.   <IMAGE>

Patent DE-3416404-A1 (DE)
Inventor: FLOHRS PETER DIPL PHYS
IPC: H01L29/06
Filed: 1984-05-04
Abstract: A monolithic integrated semi-conductor arrangement in which the breakdown voltage is adjusted by a cover electrode (7) in the pn junction region. A suitable voltage is applied to this cover electrode (7) via a voltage divider (1) in order to adjust the breakdown voltage. To obtain a breakdown voltage which is essentially independent of temperature it is envisaged that the voltage divider(1) consists of diffused zones, which have differentiated dopings. The different temperature coefficients thus produced for the resistances (R1, R2) of the voltage divider (1) cause a temperature-dependent voltage change in the cover electrode , with the result that the breakdown voltage temperature is stabilized.

Title: Device for safeguarding the return-run temperature rise in the boiler circuit of a heating boiler
Inventor: ESCH FRIEDRICH DIPL ING
IPC: F24D19/10
Filed: 1984-05-16
Abstract: The device illustrated in Figure 1 serves to safeguard the return-run temperature rise in the boiler circuit of a heating boiler 19, in which, for example, a tube set 1 is arranged. Heating takes place with the aid of long-flaming and gas-rich fuels, such as in particular wood. The boiler circuit is connected with its forward run 5 and return run 6 to the heating circuit with return run 7 and forward run 8, a pump 12 with adjustable temperature sensor being arranged in the boiler forward run 5. The boiler circuit is bridged by a bypass 21 with control valve 11 which is controlled with the sensor arranged in the boiler return run 6 via a temperature control 10. The more the water temperature prevailing in the heating circuit is raised to the level of the temperature prevailing in the boiler circuit, the control valve 11 closes the bypass 21 so that, with increasing temperature adaptation, ever more water flows out of the heating return run 7 through the tube set 1. <IMAGE>

Title: Photo-electrochemical solar cell and process for producing a substrate for such a solar cell
Inventor: MENEZES SHALINI
IPC: H01G9/20
Filed: 1984-08-24
Abstract: In the case of photo-electrochemical solar cells - PECS - the achievable efficiency of approximately 10% is crucially determined by the semiconductor material for the working electrode, the composition of the electrolyte fluid and the combination of electrode and material/electrolyte. At the same time, the semiconductor material should not be too expensive, should have a short absorption mean free path for light and be stable against photocorrosion, and the electrolyte used should be nontoxic and not require a hermetic seal. This is achieved by a ternary compound of the material systems CuInSe2 or CuInS2, including the homogeneity regions and surface modifications generated in situ of said compounds, and by a iodine/iodide solution, preferably containing a stabiliser comprising a transition metal halide. The production of a substrate is carried out as the specific formation of a surface film - heterostructure with pn junction in the boundary layer - on monocrystalline or polycrystalline semiconductor material, especially CuInSe2, by first repeatedly etching/rinsing and exposing the semiconductor material dipped in electrolyte solution, i.e. repeated cyclic polarisation between two potential limits, and then exposing the material at the operating point over an extended period. The advantage consists in a very high potential for efficient solar energy conversion.

Title: Rotary piston engine with sliding vanes mounted for rotary oscillation on the outer mating body
Inventor: EISELE MARTIN
IPC: F01C1/356
Filed: 1984-09-11
Abstract: In comparison with reciprocating-piston engines, rotary piston engines have the advantage that they need less energy for their own requirements since relatively large masses subject to a continuous change in direction under high acceleration, such as connecting rods and pistons, are absent. In continuous operation, however, the rotary piston engine is inferior to the reciprocating-piston engine since the lubricating and sealing problems have not yet been satisfactorily solved. On the other hand, rotary piston engines differ in that the rotor can be arranged as an inner or outer mating body. According to the invention, the rotor, i.e. the rotating mating body, is to be arranged externally over the fixed mating body. This leads to a larger lever arm and, accordingly, to a higher torque and smoother engine running. Eccentric arrangement of the inner mating body relative to the outer mating body gives an expansion chamber which is larger than the intake and compression chamber and a larger pressure and temperature drop is thereby achieved.
