Abstract: A laboratory centrifuge is known having a rotor which is arranged in a housing with a lid and is driven by a motor, the drive shaft being vertically aligned and having a positively guided air cooling in which air intake takes place in the direction of the axis of the shaft. In order to disclose a simple and economical air-cooled centrifuge in which cooling air reliably sucks neither air-borne particulates into the sample nor entrains air-borne particulates out of the rotor housing even in the event of a specimen tube breaking, the rotor is surrounded by an aerosol-tight container, a ventilation wheel is positioned on the power take-up side end of the shaft and there are openings in the floor surface of the housing below the ventilation wheel, through which openings the air is sucked into the housing and guided upwards, distributed axially along the walls of the container, via the ventilation wheel.

Abstract: A process for preparing an injection-molded article having a three dimensional pattern on a surface thereof includes placing a master film of a thermoplastic resin having a three-dimensional master pattern formed on a region thereof into a mold such that the master pattern is exposed to the mold cavity. An injection-moldable resin is then injected into the mold cavity so as to cause a surface region of the resin to conform to the three-dimensional master pattern on the master film, and thereby to transfer the master pattern to the said surface region of the resin. The master film is then removed to expose the three-dimensional pattern formed on the resin.

Abstract: An apparatus and method is described for detecting focus errors in an optical head by positioning a prism (17) in the optical path of a return light beam (14) reflected from an optical recording medium (16). The prism reduces the beam in one dimension by a factor of M and concurrently increases the divergence/convergence angle associated with a focus-error of the beam by a factor of M in said dimension, thereby desirably enhancing the focus error signal (FES) by a factor of M². A focus error is detected by a segmented photodetector (19) having inner and outer photosensitive regions. The photo­detector generates an electrical signal indicative of the focus error from the difference in light intensities at the inner and outer regions. The photodetector preferably is segmented in such manner as to also provide a track error signal.

Abstract: The invention relates to a holding rail for interchangeable information carriers, which has an attachment part for fastening to edge regions of shelves, containers and the like. A receiving pocket, formed by a rear wall and a transparent front wall, for the information carriers can be fastened to the attachment part. In this case, the rear wall and the front wall are connected to one another at their base in an articulated manner and the upper edge of the rear wall grips over the free edge of the front wall so as to cover it. The essential inventive feature of such a holding rail is seen in the fact that a strip-type flexible connecting element (2) is arranged between the attachment part (3) and the rear wall (12). This connecting element (2) is connected non-positively by its free end regions (21, 22) extending longitudinally, on the one hand, to the attachment part (3) and, on the other hand, to the rear wall (12). With its central region, it bridges the gap between the attachment part (3) and the rear wall (12) in a fastening manner.

Abstract: A magneto-optical disk comprises a substrate (1) whereon a recording medium (2) is formed, and a depression (1b) is formed on the substrate radially inwardly of the recording medium. A center hub (4) is installed on the depression such that the surface of the center hub is substantially level with the surface of a protective resin layer (3) covering the recording medium. On the center hub, a flying head performs CSS (Contact Start and Stop). This configuration of the disk eliminates the occurrence of dust due to the abrasion and head crash, and achieves stable CSS. A method of manufacturing such a magneto-optical disk includes the step of forming the protective resin layer after installing the center hub on the depression. In this method, since no space is produced between the center hub and the protective resin layer, stable flying characteristics of the head are obtained. Also, a magneto-optical disk is provided whereon small physical bumps and pits (15) are formed on the substrate (1) at a region (B₂) lying radially inwardly of the recording medium, to prevent the flying head from sticking to the disk. A method of manufacturing this magneto-optical disk employs a stamper (16), which permits the disk to be mass produced.

Abstract: A static random-access memory is disclosed which utilizes bit line pairs for each column of memory cells for communication of data between external data terminals and the memory cells. A precharge transistor is connected between each bit line and a precharge voltage, for example V cc , and an equilibration transistor is connected between the bit lines in each bit line pair. The precharge and equilibration transistors are controlled according to selection of the column, so that all columns which are not selected by the column address are precharged and equilibrated, including the unselected columns in the same sub-array as the selected columns. In an additional embodiment of the invention, a data transition detection circuit also controls the precharge and equilibration transistors, so that the precharge and equilibration transistors for the selected columns are turned on responsive to an input data transition during a write operation; this assists the write drivers in more quickly writing the new data onto the bit lines. Source followers are provided in the write drivers, connected to the input/output lines, to assist in the write recovery (i.e., in pulling the input/output lines high upon completion of the write operation), without requiring critical timing control. The source followers also serve to clamp the bit line voltage swing during a read, without providing a load on the bit lines during establishment of the differential voltage thereupon.
