Patent DE-19649075-A1 (DE)
Title: External expansion bus interface circuit
Inventor: MITSUDA MAKOTO
IPC: G06F3/06
Filed: 1996-11-27
Abstract: The interface circuit (15) connects a peripheral device to a microcontroller unit (1) to exchange digital information in an external expanded memory mode of the microcontroller (1).  The circuit includes a memory unit (23,24) for storing the data.  The circuit also includes an address decoder (27a) to receive the data, an address strobe and a write strobe from the microcontroller (1). The address decoder generates a release signal to release the memory device, to store the data at an address allocated to that data. The expansion circuit may be used in a digital display and a playback device which exchanges the digital information between a peripheral device and a microcontroller.  The device includes a second memory device to store the digital information.

Patent DE-19702390-A1 (DE)
Inventor: WICKERN GERHARD DR
IPC: G01M9/04
Filed: 1997-01-24
Abstract: The invention relates to a wind tunnel (1), in particular for aero-acoustic measuring, with closed air conduction and a free jet measuring section, whereby measures are taken to avoid or at least reduce disruptive aerodynamic oscillation. This is achieved, in accordance with the invention, by fitting a device, in particular one or several loud speaker units (33-35), to initiate aerodynamic oscillations in opposition of phase. This system makes it possible to avoid in particular the phenomenon that occurs in wind tunnels with closed air conduction and free jet working section (so-called Göttinger type), in the form of low frequency aerodynamic oscillation which develops at certain aerodynamic speeds and is likely to generate resonance inside the tunnel.

Title: Plastic housing for servo equipment of radio=control system for model vehicles
Inventor: VOLZ MICHAEL ALBERT
IPC: H05K5/00
Filed: 1997-02-25
Abstract: In the manufacture of  a housing for the servo equipment of a radio-controlled unit for a model vehicle,  a cut plastic film section, preferably of acrylonitrile-butadiene-styrene copolymer(ABS), is thermoformed in a solid phase pressure forming process to produce a housing shell(27) with a collar-like region(26) at the surrounding edge and after installing the servo equipment(29) a flat film section(24) is welded, bonded or clipped onto the collar-shaped region.     In an process variation two separate housing shells are thermoformed, the servo equipment is positioned inside and the shells are placed together with their open edges overlapping before welding, bonding or clipping together.      A housing (claimed) comprises a cylindrical or prismatic shell(27) of thermoformed plastic film, especially ABS, with a surrounding edge region(26) on the open side and a flat film cover(24) welded, bonded, or clipped to the edge region. Openings or bores(28,28') in the housing parts  a nd/or the cover(24) allow passage of the servo equipment shaft(29) and/or cables.      A further claimed housing comprises two thermoformed shells of plastic film, especially ABS, each with flange-like edge areas around the opposing open ends  which are bonded, welded or clipped together to connect both shells. In another housing design the surrounding edge area of one housing shell is slightly widened relative to the second shell, enabling one to slide inside the other before connecting both shells as previously described.

Title: Casting kit e.g. for manufacture of dental prostheses
Inventor: SCHREIBER HANS DR DR
IPC: A61C13/20
Filed: 1997-05-22
Abstract: The kit is used for sinter pressureless casting especially in dental restoration work. It involves casting in an optionally catalytically cured plastics material. At least one casting rod or pin is used which is preferably made of small graphite tubes and which determines the pre-heating time and the casting. After suitable embedding in a modified muffle with compressed quartz near to the casting, inductive heating is effected to give a short pressureless surface sintering without significant volume shrinkage. The preheating, burning away of the plastics and casting are then carried out.

Title: Manufacture of hologram transfers for security applications
Inventor: KAULE WITTICH DR
IPC: B29C39/14
Filed: 1997-10-20
Abstract: During coating (10,11) of the plastics backing sheet, and during the subsequent impressing operation, viscosity of the coated layer is adjusted to a predetermined value and is held constant in each case. Independent claims are included for the equipment carrying out the process and its use in making secure documents or security items. Preferred features: The coating has temperature-dependent viscosity. This is adjusted for each process, aided by a temperature controller and heating or cooling apparatus. The coating is preferably applied using screen, intaglio or flexographic printing. The printing machine is part-heated during printing. Following application, the coating is distributed over the surface. Distribution is achieved by flowing or leveling (20) over the surface. During distribution, the coating is heated, e.g. by infra red radiation. The coating is cooled during impressing (31). The coating is hardened by free radicals, or cationically.

Title: Linear mover with rail-parallel feed rod and roller grooves
Inventor: ISHIKAWA HIROKAZU
IPC: F16H25/20
Filed: 1997-10-24
Abstract: The nut sector (8) forms part of the reverser passage (14) and one position of the centre axis of the tapped bore (7) of sector (8) is determined by a position of the reversing passage part (14) using the position of the counter-roller groove (10). Passage part (14) has an inner part (15) forming the inner guide face for the reversing passage (13) as compared with the outer part (16) forming the outer guide face. The nut sector (8) should be integrated with the inner part (15). Thus inner part and sector (8) are moulded integrally to the block (12), one block position defined by a casting mould filled out with moulding material. The nut sector (8) is divided into two by a slot (17) on this, the phase shifts to differ as between these two sector parts. A spacing mechanism for the two sector parts ensures that these remain out of phase. Additional components include the block being moved (5) with block (12) as specified plus the groove balls (6), using sector (8) bore (7) to take the adjuster rod etc (3) as used. The block is moved parallel to rail (2) and block, with the balls riding in the two counter-directed grooves (10,11).

Filed: 1997-12-29
Abstract: The invention relates to an exhaust-gas cleaning device of an internal combustion engine with more than one cylinder, comprising an NOx storage catalytic converter positioned downstream from the internal combustion engine. The exhaust gas continuously flows into the NOx storage element of the catalytic converter in such a way that the NOx is absorbed in the NOx storage element as soon as the machine is run on a lean mixture and that NOx is released as soon as the oxygen concentration of the exhaust gas decreases, such that during the NOx release phase the engine is run at a gross  lambda  value which is slightly higher than the stoichiometric ratio of  lambda  = 1. To generate the near-stiochiometric exhaust gas flow with a gross value of  lambda >/=1 some of the engine cylinders selectively and individually receive an enriched mixture while the remaining cylinders continue to be run on a lean mixture.

Abstract: The navigation system includes a topographic data storage (2a) which provides plane coordinates with height values of the represented components. Also a map data storage (2b), which stores data of map indicating components including road and place names. An input unit (1) receives indicating ref. point data and line of sight angle, by which position and directions of indicated map are derived.

A determination block (3.3) indicates the reference point height and a determination block (3.4) determines ground survey coordinates, processing data from the input unit and the block (3.3). A determination block (3.5) produces map component heights from the storage (2b) inside the area and information from the other blocks. A coordinate transformation block (3.6) based on data from the block (3.4) and from the input unit provides a perspective projection transformation on the data from the model block. A drawing processing block (3.7) produces a stereoscopic map image.
