Abstract: An apparatus for detecting the presence and/or concentration of biomolecules (41a-41c), in particular DNA, comprises a boundary surface (39) between an optically denser medium (here a glass prism 35) and an optically rarer medium (here a solvent 40). Biomolecules (41a-41c) adsorb to said boundary surface (39) and alter the characteristics of impinging light. The apparatus uses surface plasmon resonance (SPR), e.g. to excite the biomolecules (41a-41c). In order to operate the apparatus at ϑ = ϑ SPR  (ϑ being the angle of incidence) and thus control the energy transferred to the biomolecules (41a-41c), the excitation light reflected at the boundary surface (39) is monitored (detector 46). The angle of incidence (ϑ) is controlled (loop 49) - e.g. by rotation of a desk - such that the intensity of the reflected light is always kept at a minimum, thus ensuring that  ϑ = ϑ SPR . The disclosure also relates to a method of controlling the angle of incidence ϑ.

Abstract: The invention relates to a method of weight-dependent controlling of the die gap of extrusion blow moulding machines in which the actual weight is compared with the desired weight of the parison and the gap width varied, the cycle time being measured, the mass throughput being determined, the actual weight of the parison being calculated from the measured cycle time and the determined mass throughput, this actual weight being compared with a preset desired weight, the actual weight being matched to the desired weight by changing the setpoint value of the wall thickness, and the cycle time modified thereby being fed back again to the setpoint cycle time by correcting the extruder speed. In order to produce multi-layer parisons, two separately controllable control loops, from weight and speed on the one hand and from gap width and cycle time on the other hand, are present in each case for at least one of the layers. <IMAGE>

Abstract: Various kinds of raw workpieces are stocked in a stocker. A predetermined kind of the workpiece is selected from the stocker with a lifter so as to move to a loading station. The workpiece is held with a vacuum pad of a loader of a workpiece carrying unit. The workpiece carrying unit is moved to a position adjacent to a laser processing machine so as to make the workpiece carrying unit stood by at the position. When machining finishes in the laser processing machine, a supporting unit like a comb of an unloader of the workpiece carrying unit is inserted below the machined workpiece, put on the table of the laser processing machine. The supporting unit is lifted up so as to pick the workpiece up out of the table. The raw workpiece is immediately put on the table with the loader. The workpiece carrying unit is moved to the unloading station. The machined workpiece is put on rollers of the unloading station with the unloader. The rollers are moved so as to drop the machined workpiece on the pallet.

Abstract: An image signal processing apparatus comprises an image pickup device (1) with color filter means having a set of luminance portions for passing a luminance component located in an offset manner and a plurality of sets of color portions for passing different color components from each other, wherein the portions of at least one color set are located in an offset manner to improve the effective resolution of the corresponding color component. The apparatus generates color difference signals from the color component signals independently of the luminance component signal, or alternatively the color portions of the filter have a high transparency, in either case to reduce the tendency of false color difference signals to be generated owing to saturation of some but not all of the signals used to generate a color difference signal. The filter portions may be arranged in pairs of adjacent rows having the same pattern of filter portions, for use with a pickup device with interlace scan.

IPC: G11C29/46
Filed: 1991-08-12
Abstract: An integrated circuit having a normal operating mode and a special operating mode, such as a special test mode, is disclosed. The special test mode is enabled by a series of signals, such as overvoltage excursions at a terminal, rather than by a single such excursion, so that it is less likely that the special test mode is entered inadvertently, such as due to noise or power-down and power-up of the device. The circuit (29) for enabling the test mode includes a series of D-type flip-flops, each of which are clocked upon detection of the overvoltage condition together with a particular logic level applied at another terminal; multiple series of flip-flops may be provided for multiple special test modes. Additional features include the provision of a power-on reset circuit which locks out the entry into the test mode during power-up of the device. Acknowledgment of the entry into test mode is provided by the presentation of a low impedance at output terminals while the device is not enabled; chip enable of the device causes the device to exit the test mode. Once in test mode, the output enable terminal of the device can provide a chip enable function.
