Abstract: The invention relates to a fluorimetric method for the quantitative determination of human serum albumin in biological fluids. The method is based on the finding that certain anionic cyanine dyes experience, in the presence of human serum albumin, a large increase in the fluorescence intensity which is used as analytical variable for the quantitative determination of human serum albumin in biological fluids. The method according to the invention can be carried out with little effort and is very sensitive and selective, so that even traces of human serum albumin in biological fluids can be determined in the presence of an excess of foreign proteins. Owing to the use of optical elements from semiconductor technology (laser diode, light-emitting diode, photodiode) all the advantages of this technology are utilised. Since methods of the state of the art either are associated with great labour intensity, time consumption and cost or are non-specific and insensitive, this method according to the invention has considerable advantages and can thus be employed as improved method for determining human serum albumin.

Abstract: A plasma processing reactor (10) is disclosed which incorporates an integral co-axial transmission line structure (32) that effects low loss, very short transmission line coupling of ac power (30) to the plasma chamber (33) and therefore permits the effective use of VHF/UHF frequencies for generating a plasma. The use of VHF/UHF frequencies within the range 50 - 800 megahertz provides commercially viable processing rates (separate or simultaneous etching and deposition) and substantial reduction in sheath voltages compared to conventional frequencies such as 13.56 MHz. As a result, the probability of damaging electrically sensitive small geometry devices is reduced.

Abstract: A particle detector (10) is designed to detect particles such as cells and blood corpuscles and includes means (14, 16, 18, 30, 32) for passing through an orifice (12) and recovering a multilayer flow consisting of an inner layer (A) of conductive liquid specimen, a middle layer (B) of conductive first sheath liquid, and an outer layer (C) of nonconductive second sheath liquid surrounding the inner and middle layers (A, B), and a pair of electrodes (16, 30) disposed upstream and downstream of the orifice (12) and in electrical contact with the conductive liquids. 
     A particle detecting apparatus incorporates the particle detector (10) and a detector circuit (44) connected to the pair of electrodes (16, 30) so as to detect particles in the conductive liquid specimen of the inner layer (A) by detecting changes in the electrical impedance between the electrodes. 
     An electric current flows from one electrode (16) to the other electrode (30) through the conductive liquids of the inner layer (A) and middle layer (B). Because the outer layer (C) is nonconductive, the current does not flow through that layer. Thus, the effective diameter of the orifice (12) is substantially the diameter (b) of the middle layer (B). 
     By varying the flow rate balance of the conductive liquids and nonconductive liquid, the diameter (b) of the middle layer (B) may be easily changed. Thus, the effective diameter (b) of the orifice (12) may be changed to optimize the detection of large or small particles in the conductive liquid specimen of the inner layer (A).

Abstract: A data cache and method provides for the handling of errors during data copy-back from a data cache write buffer to external memory in a processing system including a processor. When data requested by the processor at an addressed storage location of the data cache is data which is valid, modified, and other than the data requested by the processor, the data is first transferred to the data cache write buffer and then written back to external memory after the requested data is fetched from a memory bus. If an error occurs during the write back of the data from the write buffer to external memory, the data is transferred from the write buffer to the storage location of the data cache originally addressed by the processor before the memory bus is released.

Abstract: The head comprises an open magnetic yoke having spaced apart outside legs, confronting pole pieces (36) and (38) spaced apart to provide a transducing gap (40) at one end, and a back closure (42) at the other end. A winding is provided on each of the outside legs, wound in a direction so that energizing the windings produces a flux that is additive at the transducing gap. A non-magnetic spacer layer (44) is positioned between parts (31) and (33) of the yoke legs beyond the transducing gap to provide vertical separation greater than the transducing gap as the yoke legs diverge to the outside legs so that the flux leakage is minimized and a high head efficiency is maintained.
