Abstract: Mutated α-amylases having a sequence derived from the sequence of the liquefied alkaline α-amylase represented by SEQ ID NO:1
by, at least, deletion or substitution by another arbitrary amino acid residue of the methionine residue at the 202-position or a position
homologous thereto; and detergent compositions containing the same. These mutated α-amylases have the optimum pH value in the alkaline
region, an excellent α-amylase activity and a high and sustained tolerance against oxidizing agents. These properties make them useful as a
component of detergent compositions containing, in particular, bleaching agents and oxidizing agents.

Abstract: Attention is paid to the phenomenon that a
static image distortion characteristic is averaged in
the width of a projection area in a scanning
direction and becomes a dynamic image distortion
characteristic, when a mask pattern is scan-exposed
onto a photosensitized substrate by a projection
exposure apparatus. At least a random component
included in the dynamic image distortion
characteristic is corrected by arranging an image
correction plate obtained by locally polishing the
surface of a transparent parallel plate. Correction
plates which minimize other aberrations beforehand
are manufactured and installed within a projection
optical path, considering that also the other
aberrations are averaged and become dynamic
aberration characteristics at the time of scan-exposure. 
     In this way, an exposure apparatus for reducing
respective aberration types caused by an illumination
optical system within an projection optical system of
the projection exposure apparatus using an
ultraviolet illumination light is provided.

Abstract: L'invention a trait à un circuit de surveillance d'une bande pour poignet à deux conducteurs qui permet à l'opérateur de se maintenir approximativement à 0 volt. Ce circuit de contrôle couple l'opérateur, par l'intermédiaire de résistances, à deux potentiels de valeur égale par rapport à la terre mais de polarité opposée. Généralement, la résistance est symétrique de chaque côté d'une bande pour poignet à deux conducteurs. Grâce à cette symétrie, l'opérateur est à la tension 0 par rapport à la terre. Un trajet conducteur permet toujours à l'opérateur de décharger tout potentiel de charge induit et ce, sans affecter les temps de déclin.

Abstract: Idle messages are transmitted by an expansion node (12) into the ring topology (10) until the first idle message arrives to the expansion node (12) after having passed through the entire ring (10). Frames may then be transmitted by the expansion node (12) at every cycle time. The expansion node (12) has an expansion buffer (34) that may receive incoming frames and stores the frames until the next cycle time. The frame stored in the buffer (34) may then be transferred to a transmission side of the expansion node (12) and transmitted into the ring topology (10). If there is no frame stored in the buffer (34) at the beginning of a new cycle time, the expansion node (12) may generate a new frame and transmit the new frame into the ring topology (10).

Abstract: An image retrieval system for retrieving images from a data base in dependence upon the degree of correspondence with a user-input target image. The target image and each image in the data base are characterized by a vector of edge characteristics within each image. Retrieval is effected by a comparison of the characteristic vectors, rather than a comparison of the images themselves. To optimize performance, a set of characteristic vectors, at different levels of abstraction of the image, are associated with each data base image; images which are similar to the target image, at any level of abstraction, are retrieved. To further optimize the speed of search, the data base is partitioned into clusters, and the search is limited to the cluster most similar to the target image.

Abstract: A method and arrangement for generating binary sequences of random numbers uses the principle of random selection of the path of photons on a beam splitter and generating a random number by using two detectors (D 1 <SUB>0</SUB>, D 2 <SUB>1</SUB>) downstream from a beam splitter (ST 2 ). To generate photons, a light source (L) of a low power is used, and an additional beam splitter (ST 1 ) is connected upstream from the beam splitter (ST 2 ). The photons emitted by the light source (L) during a predefined measurement time are split by the beam splitters (ST 1 , ST 2 ) arranged one after the other in the beam path of the light source (L). The random sequence is generated when the splitting of the photons matches a predefined photon scheme.

Abstract: Disclosed is a method for producing (-)cis-3-hydroxy-1-methyl-4-(2,4,6-trimethoxyphenyl)-piperidine characterised in that 1-methyl-piperidine-4-one is converted into hydrobromide, subsequently transformed with bromine into 3(R,S)-bromine-1-methyl-4-oxo-piperidine-hydrobromide and reacted with 1,3,5-trimethoxybenzol to form 3(R,S)-bromine-1-methyl-4-(2,4,6-trimethoxyphenyl)-1,2,3,6-tetrahydro-pyridine-hydrobromide. By stirring the reaction solution into an organic solvent, 3(R,S)-bromine-1-methyl-4-(2,4,6-trimethoxyphenyl)-1,2,3,6-tetrahydro-pyridine-hydrobromide is initially isolated as a solid and subsequently the product is mixed with water and converted into 3(R,S)-hydroxy-1-methyl-4-(2,4,6-trimethoxyphenyl)-1,2,3,6-tetrahydro-pyridine by means of stirring. The product thus prepared is catalytically hydrogenated into a racemic 3,4-cis-alcahol and subsequently, enantiomerically pure (-)cis-3-hydroxy-1-methyl-4-(2,4,6-trimethoxyphenyl)-piperidine is obtained by separation of racemic mixtures with chiral auxiliary reagents from racemic 3,4-cis alcohol.

Abstract: A process for the alkylation of an aromatic substrate over a molecular sieve zeolite
catalyst involving supplying an aromatic substrate to a reaction zone containing the catalyst. The
molecular sieve catalyst is an effective aromatic alkylation catalyst and comprises a modified
zeolite beta alkylation catalyst having an intergrowth of a ZSM-12 crystalline framework within
the crystalline framework of zeolite beta. An alkylating agent is also supplied to the reaction
zone which is operated under temperature and pressure conditions effective to cause alkylation
of the aromatic substrate by the alklating agent. An alkylated substrate is recovered from the
reaction zone. 
     A specific catalyst used in the invention is characterized by an x-ray diffraction pattern
characteristic of zeolite beta and having a maximum peak at an interplanar spacing D of
4.0/±0.1A and secondary peaks S 1  at a D spacing of 11.4±.2A, S 2  at a D spacing of 4.2±.1A
and a secondary doublet S 3 , S 4  at D spacings within the range of about 3.0-3.4±.1A, and further
comprising a first secondary peak characteristic of ZSM-12 occurring at an interplanar spacing
D 10.0±2A and additional secondary peaks characteristic of ZSM-12 at D spacings less than
the D spacing of said primary peak but greater than the D spacing of said doublet S 3 , S 4 .
Specifically, the aromatic substrate is benzene and the alkylating agent is a C 2 -C 4  alkylating
agent, specifically ethylene. In a specific embodiment of the invention, there is provided a
process for the production of ethylbenzene by the liquid phase ethylation of benzene. In this
embodiment of the invention, benzene and an ethylating agent are supplied to a reaction zone
comprising a modified zeolite beta alkylation catalyst. The reaction zone is operated under
temperature and pressure conditions to maintain the benzene in the liquid phase to cause 
monoethylation of the benzene under conditions which the xylene produced in the reaction zone
is no more than 0.05 wt.% based upon the amount of ethylbenzene produced. The toluene in
the reaction zone is no more than 0.1 wt.% based upon the amount of ethylbenzene produced.
