Patent EP-0530922-A2 (EP)
Inventor: BIRD KENNETH ALFRED
IPC: G01N21/94
Filed: 1992-09-03
Abstract: A method and apparatus for the inspection and handling of surface level defects is taught. Briefly stated, the object to be inspected is positioned. A laser light (195) is polarized into at least one orientation and then reflected off of a rotated polygon mirror (210). This causes the light to "move" over the area of interest. A plurality of fiber optic bundles (42,56,58,60,62) are used to receive and conduct the reflected light back to photomultipliers. The photomultiplers convert the light into electrical signals while associated electronics digitize the signals, keeping track of pixels which are produced. By keeping track of pixel edge boundaries and determining if certain thresholds are exceeded or not met as appropriate, the area of interest can be checked for a variety of defects. By comparison of the defects to a reference base, the defects and hence the items inspected can be categorized.

Abstract: The invention relates to a regulating stage of textile industry, in which the delay of the fibre tape is variable under open-loop and/or closed-loop control. It is the object of the invention to analyse electrical signals or measurement values of a stage so that, on the basis of these analyses, corrections can be carried out. The object is achieved by the fact that additional, time-related signal analyses are made independently for the regulation. They enable correctable deviations to be detected within the analysed signals and suitable correction values to be formed. If deviations occur outside a tolerance, it is detected, in interaction with the knowledge memory of a computer, whether the deviation occurred due to a disturbance in the machine or whether the deviation can be explained as a logical consequence. <IMAGE>

Abstract: A method of thinning SOI films for providing ultra-thin active device regions having excellent thickness uniformity and further having self-aligned isolation regions between the active device regions is disclosed. A substrate (16) having an isolation layer (14) formed thereon and further having a single crystal silicon (12) layer formed upon the isolation layer is first provided. A thermal oxide layer (18) is grown upon the silicon layer, patterned in desired regions corresponding to polish stop regions positioned between predetermined active device regions, and etched. The underlying silicon layer (12) is thereafter etched according to the patterned thermal oxide layer (18) with a high selectivity etch, thereby creating grooves (22) in the silicon layer.Optionally, a thin buffer oxide layer (26) is grown upon side wall edges. A layer (28) of an insulative polish stop material is then blanket deposited. A polysilicon layer (30) is then deposited upon the polish stop material to further completely fill the grooves and then is planarized down to the top polish stop material. The top polish stop material and the oxide layer are then etched away. Lastly, by chemical-mechanical polishing, the silicon, sidewall polish stop material, and polysilicon are thinned down to the bottom polish stop material, whereby active device regions (32) having uniform thickness corresponding to the thickness of the bottom polish stop material are created between insulating regions (40).

Abstract: The invention relates to a vehicle tyre with a profiled tread pattern on the circumference (pitches) of which at least two different lengths are arranged, the tread being divided axially into a plurality of parts and the subsequent pitch lengths forming a sequence in each of the axial parts. In order to reduce further the fluctuations in radial force which cause wheel suspension components and vehicle body components to vibrate as a result of the transmission of solid-borne sound, it is proposed to dimension the phase offset between the pitch sequences of the different tread parts in such a way that the distance between the absolute extremes of the total of the weighted mappings according to a function defined below is at a minimum or is at most 25% greater than this minimum. At the same time, each part of the tread is assigned a function which is the adjacent erosion of the successive pitches of the respective part of the tread on the abscissa accompanied by erosion of the respective pitch length starting from the abscissa on the ordinate. A "mapping" of each of these functions is determined and is the remainder after the elimination of all the harmonic components higher than the x-th order, x being an integer between 8 and 14. In order to determine this remainder the function is initially analysed harmonically from the first to the x-th order and the mapping is acquired by synthesis from these data including the phase information.

Abstract: An object of the invention is to provide a coordinate input apparatus which phase-shifts an input signal in accordance with temperature and corrects a phase shift due to a change in temperature, thereby performing coordinate input. A phase shift unit of a temperature phase shift circuit is constituted by connecting two thermistors having the same temperature characteristics and two capacitors having the same capacitance to constitute a bridge circuit. An output (Eout) has a gain of 1 with respect to an input (Ein) and is phase-shifted by            tan       -1           [(-2ωCR)/±(1-ωCR)       2       )]          , where R represents a value which exponentially varies in accordance with temperature. For this reason, the output signal can be phase-shifted in accordance with a change in temperature. When this circuit is applied to a coordinate input apparatus using an ultrasonic wave vibration, the phase shift of a vibration due to variations in temperature is corrected, thereby enabling coordinate input stable with respect to changes in temperature.
