Compression molded articles employing circumferential surfaces having friction-enhancing patterns to contact substrates during wet chemical processes are disclosed. An article such as an annular body may be formed by a compression molding technique. By including a patterned surface as part of an outer circumferential surface of the annular body, frictional contact between the annular body and the substrate may be enhanced as friction-reducing fluids associated with a wet chemical processes may be directed away from the desired friction contact area between the annular body and the substrate. In this manner, frictional contact may be enhanced and the substrate may be effectively positioned and moved during the wet chemical process to improve the effectively of the process.

A disk structure is disposed in an optical tweezers device including a light source for producing incident laser light. The disk structure includes a first substrate, a second substrate and a reflective layer. The second substrate is disposed with respect to the first substrate. One of the first substrate and the second substrate has at least one flow path. The reflective layer, which is adhered to the second substrate, is disposed between the first substrate and the second substrate. After the incident laser light passes through the first substrate and then reaches the reflective layer, the incident laser light is reflected back as reflective laser light by the reflective layer to form reflective laser light. A tweezers light field is formed in the flow path by both the reflective laser light and the incident laser light.

In connection with wafer planarization, an apparatus for forming a layer of material having a substantially uniform thickness and substantially parallel first and second major surfaces includes a pair of pressing elements and a stop. Each of the pair of pressing elements has a flat pressing surface. The pressing surfaces are opposed to one another and operable to compress a quantity of the material therebetween. The stop is positioned at least partially between the pressing surfaces and has a thickness substantially equal to the desired uniform thickness of the layer. The stop is positioned to establish a spacing between the flat pressing surfaces that is substantially equal to the thickness of the stop and thereby to the desired uniform thickness of the layer when the pressing elements engage the stop. As a result, engagement of the stop by the pressing surfaces during pressing of the material forms a layer of the material of substantially uniform thickness with substantially parallel major surfaces formed by the flat pressing surfaces. The layer is then used in semiconductor processing to provide a flat surface on a layer of a substrate assembly, thereby enhancing the planarization of the substrate assembly.

The invention relates to a tablet which is rapidly disintegrated in an oral cavity containing an active ingredient at a high content and a production method thereof. That is, the present invention provides a tablet which is rapidly disintegrated in an oral cavity containing an active ingredient in not less than 25% of the total weight, having a disintegration time of within 40 seconds and an absolute hardness of 1.8 N/mm2 or more, which is obtained by granulating a powder containing an active ingredient with a binding solution containing mannitol and corn-derived pregelatinized starch, mixing the resulting granules with at least one kind of a disintegrant selected from cornstarch, hydroxypropylstarch, carmellose and crospovidone, and compression molding the mixture.

摘要:
There is provided a method for forming joints between components, comprising selecting the components; selecting an ultrasound emitting source; and exposing a region of contact between the components to ultrasounds emitted by the ultrasound emitting source, to form a melted phase, a structural interface at the region of the joint being formed by engagement of the melted phase with the components. The two components may be of similar or dissimilar materials.

A method and apparatus for making biological discs comprises the steps and means for welding the longitudinal edges of a pair of identical rectangular plastic sheets together to form a single large sheet. This single large sheet is conveyed to a heating and vacuum forming station where the sheet is heated and vacuum formed to have a plurality of convex cup-like projections formed in the surface thereof. The sheet is then moved to a cutting station where heating mechanisms form openings therein for accommodating an axle and a plurality of tie rods, and the sheet is cut in circular configuration by a cutting device shiftable on a radius of predetermined magnitude.
