Abstract: A magnetic disk substrate polishing assembly used for polishing a surface (33) of a disk substrate (34) as the disk substrate is rotated, comprises a polish roller (58) having a polish cloth or polish tape (46) conti­nuously fed thereon. The polish roller (46) is rotatably mounted on an assembly housing (56) with the polish roller disposed adjacent the rotating disk. The polish roller (46) is movable towards and away from the surface of the disk substrate, and is biased by a spring (88) in a direction towards and perpendicular to the surface of the disk substrate so as to be pressed against the surface of the disk substrate with the polish tape therebetween. This allows the roller with the polish tape thereon to conform to the surface of the disk substrate, so as to reduce ripples and make a uniform pattern on the polished surface of the disk substrate when the polishing operation is completed.

Abstract: An input waveform signal is converted into a digital peak value signal by an A/D converter (8), and the digital peak value signal is input to one input ter­minal A of a comparator (42). The other input terminal B of the comparator (42) receives a preset digital peak value signal from a memory (43). These input signals are compared by the comparator (42). The content of the memory (43) is reduced at a predetermined rate. If the comparator (42) detects that the currently input wave­form level is larger than the continuously reduced level of the memory, i.e., if A > B, a new waveform level is loaded in the memory (43). As a result, the output from the comparator is inverted. That is, condition A > B is changed into condition A < B. The timing of this change in condition serves as a peak timing of the input wave­form signal.

Abstract: Alignment difficulties in optical computing arrangements are overcome by integrating the optical components on a single substrate and arranging the elements in a manner that causes them to interact with one another to perform the desired function. The substrate has one or two major surfaces and the elements are grown or fabricated on those surfaces using conventional integrated circuit manufacturing techniques. Recognizing that an optical circuit can be larger than what can be fabricated on a single substrate, aligning structures are fabricated onto substrates that need to be coupled to form the optical circuit. The aligning structures contain registrable protrusion and indentation portions, such as ridges and grooves, that are imbedded into the substrates as part of the manufacturing process of the optical elements. Most advantageously, the position-sensitive optical devices are manufactured on one side.

Abstract: In the case of an injection moulding method for making hollow plastic objects, in which a fluid is forced into the mould under pressure immediately after injecting the plastic polymer melt, so that the polymer melt spreads out over the surface of the mould cavity, the fluid is forced into the mould cavity through an injection sleeve, which is in the inner sprue region of the moulding and is surrounded by flowing plastic polymer melt, so that the forced-in fluid reaches the mould cavity without first coming into contact with the plastic polymer melt. The apparatus for making such plastic objects has an injection sleeve, provided at a distance in the inner sprue region of the moulding, for the fluid feed into the plastic polymer melt injected into the mould cavity, which sleeve controls the direction of the flowing-out fluid in such a way that it coincides with the direction of melt thrust in the mould cavity. <IMAGE>
