Abstract: A system receives output signals from a well tool adapted to be disposed in a wellbore and, after appropriate processing of the signals, generates a set of invasion parameters which are used for plotting a resistivity log on an output record medium. The invasion parameters include Rxo, the flushed zone resistivity; Rt, the uninvaded zone resistivity; and two other parameters not previously known, the "w" parameter and the "N" parameter. "w" represents the midpoint of the transition zone region on the resistivity log and "N" represents a value related to the slope of the resistivity log in the transition zone region. Given the four parameters, Rxo, Rt, w, and N, a more accurate resistivity log may be generated and illustrated on an output record medium. The system uses an iterative procedure wherein physical values of Rxo, Rt, w, and N are selected; in addition, an additional constraint value is selected. A cost function "chi squared", a function of the squares of differences between measured and modeled apparent conductivity (resistivity), is computed. The chi-squared cost function is then minimized. The chi-squared is minimized by first determining if the difference between the new versus old chi-squared changed less than a desired amount a required number of times, and secondly determining if the ratio of the constraint to the chi-squared has resulted in a required a-priori value a required number of times in a row. When the chi-squared is minimized, the parameters utilized to determine the chi-squared are the required invasion parameters used to plot the more accurate and improved resistivity log output record medium, one which reflects a gradual change in resistivity in the transition zone.

Abstract: The apparatus and method of the present invention quickly determines the presence of contours in a digital color image by determining the busy and the non-busy (smooth) regions of the original digital color image and determining the luminance variations in the smooth regions of the original digital color image and in a quantized version of the original digital color image. The difference between the luminance variations is compared against a selected threshold value, which if exceeded causes a mark to be associated with the pixel under consideration. For each pixel of the quantized digital color image that is associated with the mark or has a mark associated with a neighboring pixel in a window around the pixel of interest the color of the pixel is selected to minimize and or remove the contour.

Abstract: A method of growing a single crystal of KTiOPO₄ which is a nonlinear optical material is disclosed. Growth of the single crystal of KTiOPO₄ is carried out by melting a KTiOPO₄ material with a flux to produce a melt, then contacting a seed crystal to the melt, and by slowly cooling at a saturation temperature or below. At this time, molar fractions of K₂O, P₂O₅ and TiO₂ contained in the melt fall within a region surrounded by six points in a K₂O-P₂O₅-TiO₂ ternary phase diagram of A (K₂O: 0.4150, P₂O₅: 0.3906, TiO₂: 0.1944), B (K₂O: 0.3750, P₂O₅: 0.3565, TiO₂: 0.2685), C (K₂O: 0.3750, P₂O₅: 0.3438, TiO₂: 0.2813), D (K₂O: 0.3850, P₂O₅: 0.3260, TiO₂: 0.2890), E (K₂O: 0.4000, P₂O₅: 0.3344, TiO₂: 0.2656), and F (K₂O: 0.4158, P₂O₅: 0.3744, TiO₂: 0.2098). In addition, K₁₅P₁₃O₄₀ or the same composition produced by melting is used as the flux, and the proportion of a KTiOPO₄ element in a composition of the melt is prescribed to 83.5 to 90.0 mol%. The seed crystal is set so that a C axis is in a direction perpendicular to a melt surface. Then, the seed crystal contacted to the melt is rotated and slowly cooled. Thus, a single crystal of KTiOPO₄ of single domain at the end of growth can be produced.

Abstract: There is shown a method and apparatus for transferring a reaction gas (12) between a high pressure environment (eg CVD reactor) and a low pressure environment (eg mass spectrometer). A baffle channel (18) is disposed in a fluid communication path between the high pressure environment (14) and the low pressure environment (16). Also disposed in the path is an element for limiting gas flow conductance. A shield gas (22) is introduced into the baffle channel and a longitudinal laminar counterflow of the shield gas established toward the high pressure environment, opposing the flow of the reaction gas toward the low pressure environment. The shield gas hinders access of the reaction gas to the element for limiting gas flow conductance, so that a desired ratio of partial pressures of the gas to be transferred in the high pressure environment exceeds the partial pressure of that gas at the end of the baffle channel nearest the low pressure environment, protecting the element for limiting gas flow conductance, and regulating the amount of reaction gas transferred into the low pressure environment.
