Abstract: In a method of manufacturing an oxide superconductive 
material, yttrium-3-ethyl-3-pentoxide and 
barium-3-ethyl-3-pentoxide are prepared as alkoxides of 
yttrium and barium. Copper-2-ethylhexanoate, being a 
carboxylate of copper, is added to the alkoxides to 
provide a raw material compound. A solvent obtained by 
mixing t-heptanol and p-xylene in the ratio of 1:5 is 
added to the raw material compound, to prepare a solution 
containing the raw material compound. Water is added to 
the solution thus obtained, which is then stirred to cause 
hydrolysis and dehydration/condensation reaction, and 
thereafter the solution is coated on a substrate of 
polycrystal YSZ. A coating film formed on the substrate 
is fired, so that a superconductive layer of Y-Ba-Cu-O

Abstract: In response to ultrafast optical signal pulses, it is now possible to 
generate correspondingly ultrafast electrical signal pulses by employing 
semiconductor apparatus including at least one quantum well layer electrically 
biased by a static electric field. Optical signal pulses incident on the quantum 
well are at a wavelength substantially less than the absorption edge of the 
quantum well layer or layers. In other words, the incident optical pulses have a 
mean photon energy less than the bandgap energy of the quantum well layer or 
layers. The electrical signal pulse generated subsists for a period of time 
substantially equal to the duration of the optical signal pulses incident on the 
quantum well layer or layers.

Title: Process and apparatus for the electrochemical, catalytic oxidation of sulphur dioxide to sulphuric acid
IPC: C01B17/80
Filed: 1988-06-29
Abstract: The electrochemical, catalytic oxidation of sulphur dioxide to sulphuric acid is carried out by bringing a gas mixture having a sulphur dioxide content of 0.01 to 50% by volume simultaneously into contact with oxygen and an electrolyte - water or a solution of sulphuric acid - over a catalyst which is activated carbon or activated carbon provided with metal complexes of organic compounds (porphyrins, anulenes, phthalocyanines, and the like) or products of their thermal decomposition, or activated carbon provided with platinum, palladium or rhodium in amounts of 0.1 to 1% by weight and has been made hydrophobic by means of hydrophobic polymer compounds (polytetrafluoroethylene, polyisobutylene, polyethylene, and the like) or by means of a mixture of a few of these compounds at a ratio of catalyst : hydrophobisizing agent of 25:1 to 1:4 at a reaction temperature of 10 to 80 DEG C. In the apparatus according to the invention, the hydrophobisized catalyst is applied as a porous catalytic layer to sheets made of a hydrophilic fibre base or a porous base, which leads to formation of a three dimensional matrix for holding back and draining the acid. These catalytic sheets are arranged such that gas ducts are formed between them whose constant volume is secured by means of spacing elements. The upper ends of the catalytic sheets are mounted in the distributing tank for the acid feed. The electrochemical, catalytic oxidation of sulphur dioxide to sulphuric acid with simultaneous participation of oxygen and water takes place in the porous layers of the hydrophobisized catalyst which forms a spacing layer between liquid phase and gas phase. <IMAGE>

Abstract: A rack for sample containers such as, e.g., test tubes which consist of M identically designed holders for linear accommodation of N sample containers in each case, as well as a stand for accommodating the M holders, which has vertical side parts, so that a plurality of the holders can be mounted on the stand parallel to one another and fixed there by means of a latching connection. 
<??>Due to this modular configuration of a rack, it is achieved that the stand enables a reliable accommodation of a plurality of holders, whereas the holder in which the sample containers can remain during all the work operations can be constructed as an inexpensive, single- use plastic part, the purpose of which is merely the linear spatial allocation of a number of sample containers and which upon termination of the measurement can be thrown away, together with the sample containers as the case may be. The sample containers can be inserted into such a holder from the beginning and also remain there, so that expensive transfer operations, which can be the cause of mix-ups and confusion, are reliably avoided during the detection steps. This is particularly of importance for carrying out immunoassay measurements.

Title: Methods of correcting multiple byte errors
IPC: G11B20/18
Filed: 1989-08-24
Abstract: A method is disclosed for correcting multibyte errors in a magnetic 
medium on which data is recorded in variable length blocks that 
comprise sub-blocks of data bytes and corresponding check bytes and 
include error correction code (ECC) for which ECC syndromes are 
generated during reading. A sequence of N sequential parity check 
bytes is written at the end of each block. After ECC syndromes are 
generated during reading, parity syndromes are generated by comparing 
parity check bytes computed from data bytes and check bytes as read 
with the parity check bytes as written. When a long-burst error 
occurs, a pointer points to the first of the N consecutive bytes in a 
block that could have been influenced by the error burst. After 
correcting correctable errors in all sub-blocks not affected by the N 
bytes identified by the pointer, and adjusting the parity syndromes for 
errors thus corrected, the adjusted parity syndromes are used to 
correct the errors in the N bytes indicated by the pointer. Unused ECC 
syndromes are then adjusted for errors corrected by the adjusted parity 
syndromes and used to correct all correctable errors then remaining.

Title: Toner concentration control method and apparatus
IPC: G03G21/00
Filed: 1989-03-14
Abstract: A patch sensing toner concentration control method and 
apparatus is provided in which the optical density of 
reproduction output can be changed without changing the 
quantity of toner that is deposited on the 
photoconductor's test patch area. The test patch area 
receives toner as the patch area passes through a 
developer station under the influence of a patch 
development electrical field or vector. Light that is 
reflected from a bare photoconductor area is compared to 
light that is reflected from a toned test patch area. The 
ratio of these two reflected light intensities is used to 
control the addition of toner to the developer station. 
Optical density of the reproduction output is changed by 
changing the toner concentration in the developer station. 
The toner concentration control method and apparatus of 
the invention is constructed and arranged to require a 
fixed or constant ratio of light reflection as an 
indication of proper toner concentration, independent of 
the absolute value of toner concentration. Toner 
concentration, and thereby optical density of reproduction 
output, is changed by changing the magnitude of the patch 
development vector, while maintaining the reproduction 
development vector constant.
