Title: Picture filing device and method thereof
IPC: H04N1/41
Filed: 1990-12-13
Abstract: A picture filing device which inputs pictures corresponding to documents as multivalued data, converts the multivalued data to binary picture data and stores the binary picture data in it, and a method of filing pictures. Picture elements in the areas having a specific color are extracted from an input picture, and luminance information representing monochromatic binary picture data and binary picture data specifying colored areas are stored on different planes respectively. On the plane for the luminance information, not only black picture elements but also other picture elements to be displayed in specific colors such as red, etc. are described inclusively. Picture elements, for example, of a red character, of a specific color to be displayed are extracted. The extracted picture elements of the specific color are recorded as "1s" on the plane of the specific color, e.g. an R-plane different from the plane for the luminance data. On the R-plane only picture elements having red color are recorded as "1s" and other picture elements are recorded as "Os". When outputting, picture elements whose contents on the plane for the luminance data are "1s" and whose contents on the R-plane are "Os" are displayed in black. Picture elements whose contents on the luminance data plane are "1s" and whose contents on the R-plane are "Os" are displayed in red.

Title: Pyridonecarboxylic acid derivative.
Inventor: HAYAKAWA ISAO
IPC: A61K31/47
Filed: 1992-05-27
Abstract: Known synthetic antibacterials having a condensed pyridonecarboxylic acid skeleton include quinolone derivatives having various substituents at various positions of the skeleton. The possibility of the presence of diastereoisomerism in these derivatives, however, gives rise to a mixture of at least four diastereomers having properties differing from one another, resulting in the difficulty in applying the same as such as a medicine. Under these circumstances the present invention provides an antibacterial 1-(1,2-cis-2-fluorocyclopropyl) quinolone derivative represented by general formula (I) comprising a single diastereoisomer even when there are various diastereoisomers thereof. In formula (I), R<1> represents methyl, difluoromethyl, etc.; R<2> represents a saturated nitrogenous heterocyclic group; A represents C-X<3> or nitrogen; X<1> and X<2> represent each independently halogen; and X<3> and Z represent each hydrogen, etc. <CHEM>

Inventor: BONIN WAYNE A
IPC: G01B7/00
Filed: 1994-10-03
Abstract: Ensemble (2) détecteur de force, de poids ou de déplacement qui comporte un système de condensateur doté de plaques d'excitation et de détection multiples montées sur un système de suspension approprié permettant d'obtenir le mouvement relatif désiré. Les plaques fixes (8, 12) sont excitées par un signal (40) porteur c.a. de l'ordre de 50 kHz, les signaux vers les plaques les plus extérieures étant déphasés de 180° les uns par rapport aux autres. Le signal de sortie passe à travers un ampli-séparateur d'impédance très élevée et est ensuite démodulé de manière synchrone pour produire un signal c.c. proportionnel à la force, au poids ou au déplacement. Une force (y compris un poids) ou un déplacement est appliqué à la plaque de détection (20). Par exemple, un porte-échantillon (24) ou un dispositif de transmission de force est monté de manière à se déplacer à l'unisson avec la plaque de détection (20). Le mouvement de la plaque de détection produit une valeur de sortie qui est proportionnelle à la position de la plaque de détection, mais qui est facilement étalonnée pour représenter la force, étant donné que le détecteur de la présente invention possède une relation déplacement/force linéaire.

Title: Vectors having enhanced expression and methods of making and uses thereof
Inventor: TARTAGLIA JAMES
IPC: A61P37/04
Filed: 1998-02-25
Abstract: Disclosed and claimed are vectors having enhanced expression and methods for making and using them. Enhancement of expression is from substantially co-temporal expression of at least one first nucleic acid molecule and at least one second nucleic acid molecule. The second nucleic acid molecule encodes a translation factor. The contemporaneous expression can be from operably linking the first and second nucleic molecules to a single promoter, or from operably linking the first nucleic acid molecule to a first promoter and the second nucleic molecule to a second promoter wherein the first and second promoters function substantially contemporaneously. Thus, the first and second nucleic acid molecules can be at the same locus in the vector or at different loci. The second nucleic acid molecule can encode encode one translation factor or more than one translation factor. The translation factor can be a K3L open reading frame, an E3L open reading frame, a VAI RNA, an EBER RNA, a sigma 3 open reading frame, a TRBP open reading frame, or combinations thereof. The vector can be a poxvirus such as an attenuated poxvirus; for instance, a NYVAC vaccinia virus or an ALVAC canarypox virus.
