Abstract: A method and an apparatus for manufacturing a polyurethane foam injected with strand mats. After a polyurethane foam solution is sprayed on the strand mats, the strand mats are moved upward and downward by prominences and depressions and then intermittently pressed by a pressing device, thereby the air in the strand mats being exhausted to the outside. Therefore, the polyurethane foam solution uniformly permeates into the strand mats. As a result, the insulating effect and mechanical strength of the polyurethane foam are increased, uniform surface with no air spaces is obtained, the mechanical properties are made uniform, and shrinkage, cracking, distortion and the like are prevented under a super-low temperature such as less than −165° C.

Abstract: A manufacturing method of a polyurethane foam injected with strand mats and a device for increasing the volume of the strand mats. The method comprises the steps of: increasing the volume of each of the strand mats to weaken the cohesion between glass fibers in each of the strand mats; continuously supplying and transferring the volume-increased strand mats; spraying a polyurethane foam solution on the continuously transferred strand mats; and foam molding the polyurethane foam solution in which the strand mats are immersed, into a polyurethane foam. Because the cohesion between the glass fibers in the strand mat is weakened and the volume of the strand mat is increased, the polyurethane foam solution uniformly permeates into the strand mats. As a result, the productivity of the polyurethane foam is improved and the variations in a variety of the mechanical properties are minimized.

Abstract: An image compression method is provided which uses a wavelet transform technique to generate transform coefficients relating to an input image. Furthermore, the method generates and encodes an efficient tree structure of the transform coefficients by performing the following steps. First, transform coefficients are obtained by transforming an input image in accordance with the wavelet transforming technique. Then, a quantizing interval which minimizes quantization errors is determined for a predetermined step size and is determined according to statistical characteristics of the input image. Then, a simple tree structure is generated based on the transform coefficients, and such tree structure is modified by using statistical characteristics of the transform coefficients to produce a monotonically decreasing tree structure. The resultant tree structure is modified by limiting a maximum height difference between parent nodes and child nodes of the tree structure to produce the tree list.

Abstract: A heating apparatus for chemical vapor deposition equipment which is capable of providing a uniform temperature distribution, even for a wafer having a large surface area. The heating apparatus may include upper and lower reflection plates, with a heater located between the reflection plates. The apparatus may also include a barrier plate to help provide a uniform heat distribution and to minimize dust generation and metallic pollution on a wafer. The apparatus may also include a heater cover for covering the upper portions of the first reflection plate, the heater and the barrier plate, and the sides thereof. The upper reflection plate, which is installed above the heater cover, may be integrally formed with a gas spraying means.

Abstract: A method for manufacturing a pressure container having opposite dome ends with different opening diameters, comprising double-stepped windings involving a primary winding carried out at a small winding angle in a polar winding manner, for forming a primary form on a mandrel provided with bosses having different diameters and a secondary winding carried out at a large winding angle in a helical winding manner, for forming a secondary form on the primary form. The polar winding is carried out under the condition that a metal inserter having a diameter similar to that of the smaller boss is mounted to the larger boss, to be protruded axially outwardly of the larger boss.
