Title: Solar-collector arrangement
Inventor: WEIGL BERND E
IPC: F24S50/20
Filed: 1993-05-25
Abstract: There is provided a solar-collector arrangement having at least one panel-like solar-collector element which is attached to a buiding or the like so as to be adjustable in the angle of inclination. In order to achieve adjustability of the angle of inclination in a constructionally simple manner, the solar-collector element is attached to the building via a first pivot bearing with a first pivot axis, and also via a second pivot bearing which comprises at least one pendulum rod mounted in articulated fashion on the solar-collector element and also the building. One of the pivot bearings is designed to be non-displaceable relative to the building and the other pivot bearing is designed to be displaceable relative to the building. In this arrangement, the first pivot bearing can be constructed on an adjusting element, for example a push rod, which is displaceable relative to the building and is associated with a driving element. If a plurality of solar-collector elements are arranged, they can be adjusted by means of a common push rod.

Abstract: In a pressure-wave machine with integral combustion, which essentially comprises a rotor (1), which rotates between two side parts (4), (5) and has cells (2), in which a constantly recurring ignition and combustion process occurs, cooling air lines (7) are arranged in the housing and ducts (3) in the rotor (1) above and below the cells (2) viewed in a radial direction. The rotor (1) may additionally be enclosed on its inner and outer circumference by at least one baffle plate (8) for the formation of further cooling ducts (6), the housing interior space of the pressure-wave machine then being connected to the low pressure outlet. For cooling the rotor of the pressure-wave machine, a small fraction of the incoming air is tapped off upstream of the fuel addition, fed through cooling air lines (7) through the housing and is then led through the ducts (3), the cooling air itself then being subjected to a separate pressure-wave process. <IMAGE>

Title: Method and device for the simulation of artificial gravity conditions
Inventor: WIMMER ULRICH DIPL ING
IPC: B64G7/00
Filed: 1994-02-25
Abstract: Method and a device are described for the simulation of artificial gravity conditions and in particular of microgravity conditions, in which a specimen capsule (sample capsule) (10), fastened on a motion apparatus (9) which can be driven and braked, moves on a total path which is composed of at least three path parts. The essential point in this case is that all of the total path is located in an essentially vertical plane, that the first path part (17) is constructed essentially like the third path part (4), enclosing between them a curved path part and forming a U-shaped total path (15), and that the motion apparatus, which is preferably a carriage (9), traverses the total path (15) once or any desired number of times periodically or in the manner of a pendulum. This provides the great advantage that a direct and continuous repetition of a simulation is possible, that the energy required by a production method can be supplied easily from outside in the form of electrical energy, and that, by using one or more start/end positions (5) laterally offset and by using a plurality of carriages (9), a rapid change between different production methods and/or production cycles can be achieved easily. <IMAGE>

Patent DE-4408292-A1 (DE)
Title: Suspension control system
Inventor: KASHIWAGI AKIRA
IPC: F16F9/516
Filed: 1994-03-11
Abstract: A suspension control system has a relative displacement sensor in order to detect a relative velocity between a vehicle body and a wheel, and a control system which sets a relatively high value as damping coefficient for the extension stroke of a hydraulic shock absorber, which is provided between the vehicle body and the wheel, when the magnitude of the relative velocity in the direction of the extension stroke exceeds a predetermined reference value, giving priority to the control on the basis of the absolute velocity of the vehicle body. When the magnitude of the relative velocity between the vehicle body and the wheel in the direction of the extension stroke exceeds the reference value whilst the vehicle is travelling, for example because a wheel drops into a depression, the damping coefficient for the extension stroke is set to a relatively high value, giving priority to the control on the basis of the absolute velocity. When the wheel drops into a depression, the occurrence of a complete rebound can therefore be prevented. The ride comfort is therefore improved.

Filed: 1994-08-30
Abstract: Method for producing a DRAM capacitor, which comprises the steps of forming a double contact hole structure by double use of an insulating separation ring or spacer, filling only the lower section of the contact hole, forming a pattern with an undercut-etched section of two insulating films which exhibit a large difference in their wet chemical etching rates, coating the pattern with a conducting layer, in order to form an insulating separation ring or a spacer from a section of the conducting layer which is arranged on the stepped pattern section, and etching the resulting structure over its entire surface, the insulating separation ring or spacer being used as a mask in order to insulate a capacitor which is ultimately to be formed, a capacitor electrode with a double right-angle frame shape being formed. With such a design, the inner surface of the contact hole can be used as part of the capacitor, it being possible to increase the surface area of the capacitor. Since a separate mask is not used for the etching step, it is possible to simplify production of a DRAM capacitor. Furthermore, the DRAM capacitor produced has a reduced contact area and an increased surface area. An increase in the capacitance and an improvement in the integration scale are thereby achieved, whereas the topology ... Original abstract incomplete. <IMAGE>
