Patent DE-4022904-A1 (DE)
Inventor: STECKENBORN ARNO DR RER NAT
IPC: H01L23/544
Filed: 1990-07-16
Abstract: In the production of three-dimensional structures made of single-crystal semi-conductor material, the orientation of the crystal lattice must be accurately known. Markers on the wafers are used for this purpose, previously in the form of a flat. In order to produce a marker giving very precise indication of the orientation of the crystal lattice of a wafer, the wafer (3) is irradiated with vertically incident X-ray radiation (30) or irradiated over a small, roughened area (10) with vertically incident radiation (6) from a laser (5). The reflected radiation (7) is detected by a video camera (9), and electrical video-camera signals corresponding to the reflected radiation (7) are processed by a computer (12) to determine the orientation of the crystal lattice. The wafer (3) is aligned with a marking device (15...20) according to the crystal-lattice orientation determined and the mark is made on the wafer (3) in the aligned position. The invention is applicable to the production of micro-mechanical components.

Title: Reducing transmitted information for stereoscopic image data - producing difference image data and combining with left channel data to define additional bit signal
Inventor: WALDOWSKI MICHAEL DR RER NAT
IPC: H04N19/597
Filed: 1991-04-05
Abstract: A processing method for stereo image transmission involves a mixed image computed from the left and right image data. The magnitude of the left image and the phase of the right image are used in a Fourier transformation process. A difference image is obtained by subtraction of the right image from the mixed image on a point for point basis. This results in a sign change and a generated bit pattern is transmitted instead of the right image. The left image is transmitted unchanged. The images are reconstructed within the receiver. ADVANTAGE - Similarities between both images of stereo pair made useful for efficient coding.

The front edge (12) of the inner bag (9) is set back in relation to the front edge (11) of the outer bag (10), which prevents the formation of air eddy currents in this area. Such currents would disturb the function of sensors fitted to the bag for measurement of required data. USE/ADVANTAGE - To reduce the shadow surfaces on an aircraft-towed aerial target bag.

Title: Energy recovery from boiler sludge - using sludge to transfer heat with min. losses to water steam circulation plant
Inventor: ECKERT ADOLF
IPC: F01K7/40
Filed: 1991-11-28
Abstract: Heat from the sludge is transferred with min. temp. loss to the water steam circulation. The sludge is forced from the release (22), which is connected on the steam side to the steam circuit of the low pressure preheater (7,9,11,13) as a preheat stage to the degasser (15) through the sludge cooler (23). The turbine condensate is heated via the sludge before the first low pressure preheater, cooled in a secondary flow through the sludge cooler and fed back into the mainstream at the final preheat stage (13). The secondary condensate flow has an equal or greater temp. increase as the mainstream, and reduces the steam power requirement of the turbine. USE/ADVANTAGE - Optimal temp. usage during recovery of heat from boiler sludge.
