Patent EP-0408265-A2 (EP)
Inventor: CHU WEI-KAN
IPC: C23C14/20
Filed: 1990-07-06
Abstract: Disclosed herein is a coated substrate and a process for forming films on substrates and for providing a particularly smooth film on a substrate. The method of this invention involves subjecting a surface of a substrate to contact with a stream of ions of an inert gas having sufficient force and energy to substantially change the surface characteristics of said substrate, and then exposing a film-forming material to a stream of ions of an inert gas having sufficient energy to vaporize the atoms of said film-forming material and to transmit the vaporized atoms to the substrate surface with sufficient force to form a film bonded to the substrate. This process is particularly useful commercially because it forms strong bonds at room temperature. 
     This invention is particularly useful for adhering a gold film to diamond and forming ohmic electrodes on diamond, but also can be used to bond other films to substrates.

Abstract: Video signal transmitting system in which digital video signal are divided into groups of predetermined frames. Digital video signals of at least one frame of them are intraframe coded and then transmitted. Remaining digital video signals are interframe coded with reference to the digital video signals, intraframe coded, and the digital video signals, intraframe coded, of a subsequent group of frames and are then transmitted. A motion vector from a predetermined reference frame is detected. Video signals are interframe coded by the motion vector to transmit the video signals. A motion vector from a frame which is frames away from the reference frame is converted to motion vector per one frame between the reference frame and the frame, is optimized, and is then transmitted.

Abstract: Special effects using polar image coordinates produce a new class of television special effects, such as spherical mapping and kaleidoscope effects. Rectangular coordinates for an input image are converted (38) into polar coordinates, and the polar coordinates are mathematically manipulated (40,42) according to the desired special effect. The modified polar coordinates may be applied (46) directly to the rectangular coordinates to produce modified rectangular coordinates that represent the desired special effect, or they may be converted (44) back into rectangular coordinates as the modified rectangular coordinates.

Abstract: In the production and machining of single-crystal material, it is important to be able to detect deviations from the ideal crystal structure. Information on the density and average extent of foreign-phase precipitates is required. …<??>The object is to carry out automatically the irradiation of discrete crystal regions with wave or particle beams, the measurement of the intensity distribution of the beams diffracted under Bragg conditions and the determination of static Debye Waller factors universally for different sample thicknesses with high resolution and flexibility in relation to wavelength changes. For this purpose, the angle of incidence of the beams with respect to the diffracting lattice planes is varied, the reflectivity is measured with a photon or particle detector and the integrated reflectivity Rint is determined. Swivelling the sample around an axis which is perpendicular to the diffracting lattice planes results in a variation in the sample thickness. Rint is measured as a function of the sample thickness. When matched to a theoretical function, the measured dependence yields the static Debye-Waller factor and, if several diffraction orders are measured, the density or number and the average extent of the precipitates. …<??>Important applications are the in-situ determination of foreign-phase precipitates, in studies of Si wafers which can be topographically mapped as a function of position in terms of the density and size of SiO2 precipitates, and the like. …<IMAGE>…

Abstract: A process for releasing leachable substances from a polymeric contact lens blank. The contact lens is confined in a cavity within a carrier to permit the hydration of the lens without permitting it to invert or roll over. A fluid flow is introduced into the cavity about the lens to extract leachable material from the lens. The process significantly reduces the amount of leaching fluid that is used and the amount of time that is needed for hydration, washing and extraction.

Abstract: A dynamic channel allocation unit (103) specifies a bit rate for each video coder in a set of parallel video coders (102-1,...102-N) comprising an overall video coder. The dynamic channel allocation unit is supplied from each individual video coder with an average frame quantization step size for the previous frame and the average number of bits produced per pel. For the current image frame the dynamic channel allocation unit computes a set of channel sharing factors, i.e., the percentage of the total channel bandwidth to be allocated to a particular video coder. One channel sharing factor is computed for each individual video coder. Individual members of the set of channel sharing factors may be further refined to reflect the prior history of the channel sharing factor for their corresponding coder. Additionally, the set of estimates may be normalized to reflect the actual number of bits that can actually be produced by each individual video coder.

Abstract: A stepper motor in a magnetic tape cartridge head positioning system applies vernier control to achieve a final target after a preliminary target has been achieved by stepping. The vernier control is provided by a closed loop servo system in which current is applied to stator coils selected so that the target is at a torque maximum rather than at a torque null. Current proportional to a servo error signal is applied to selected stator coils so that the torque is sufficiently linearly related to position to permit classical linear servo analysis for the design of a stable, non-oscillating system. An example of stator coil selection for advancing and retarding a permanent magnet stepper motor operated in eight half steps is provided below in Table 1.

Abstract: 2.1. In the transporting of a line of packages (12) consisting of a plurality of superposed rows (13, 14, 15, 16) of cuboid packages (10), it is necessary to compensate differences of position between the individual rows (13...16). A correct relative position is to be achieved in order to permit the transverse pushing-off of groups (11) of packages as part of the line (12) of packages. A row which is situated to the rearward in the direction of transporting is advanced into the correct relative position by an assigned additional conveying member, in particular by a conveyor belt (28). 2.2. The adjustment of the rows (13...16) takes place at the end of a conveying cycle, when the line (12) of packages runs against a stop (guide 18). A row which is situated towards the rear is advanced by the conveyor belts (28) until it contacts the stop. <IMAGE>
