Abstract: A method for manufacturing a high Cr system seamless steel pipe having a high inside surface quality with a high efficiency and at a reduced production cost is provided. An initial material including Cr at a content of 10 to 20 %, and impurities S and P at respective contents of not more than 0.050 % is used to form a finished pipe, and when using parameters, the total soaking period .SIGMA. t1 (hours) for soaking the initial material to form a primary pipe material as a billet or bloom and the total soaking period .SIGMA. t2 (hours) for soaking the primary pipe material, a finished pipe is formed at a heating temperature of 1,200 °C under the condition that the following equation (b) is satisfied:     (see formula I) where f is a factor indicating the degree of generating the .delta. ferrites in accordance with the contents of elements included therein. The method allows a high Cr system seamless steel pipe having a very small amount of inside surface defects to be formed, using a high Cr steel. Since a predetermined productivity can be attained without any excessive addition of impurities, a high Cr system seamless steel pipe having a high inside surface quality can be produced with a high efficiency.

Title: Dual-chamber type prefilled syringe
Inventor: KATO MASAHIKO
IPC: A61M5/28
Filed: 2002-08-14
Abstract: A dual-chamber type prefilled syringe comprises a cylindrical member made of glass or the like, an interior area of which is partitioned into a front chamber and a rear chamber by a plurality of plug members. The respective chambers preliminarily and independently contain injection medicine and its dissolving solution or the like.   An end plug member (13) is inserted and fitted into a side of a base end portion (4) of the cylindrical member (2). A middle plug member (14) is arranged between a front end portion (3) and the end plug member (13). The cylindrical member (2) has an inner surface between the front end portion (3) and the end plug member (14), projected outwards to provide a bypass (20) shaped like a groove. The bypass (20) has a length in a direction of an axis (19) of the cylindrical member (2), which is made longer than the middle plug member (14).  The bypass (20) has an inner surface the end surface of which is situated on a side of an inlet (21) formed on the side of the base end portion (4) and uprises outwards by an angle (0) which is formed larger than 45 degrees with respect to the axis (19) of the cylindrical member (2).   It is possible to reduce a phenomenon in which the dissolving solution or the like liquid agent splashes out of the bypass when communicating the front chamber with the rear chamber, which results in the possibility of effectively preventing the leakage of the liquid agent from a front end of an injection needle.

Filed: 2003-06-05
Abstract: The present invention pertains to a process and to a device for printing a multicolor image composed of at least two varicolored partial images on a surface. A first partial image (4C) is transferred onto the surface in an ink transfer position (5) and at least a second partial image (4B) is transferred onto the surface in the same ink transfer position (5) and is superimposed to the first partial image. The partial images transferred onto the surface are dried (10) at least partially or hardened at least partially between the ink transfer steps. The drying step is carried out according to the present invention in the ink transfer position. High print quality can be achieved according to the present invention in a simple manner because the first partial image set and dried partially or also the respective additional, partially dried partial images always have well-defined surface properties.

Abstract: Un plan d'exécution de frittage permet la formation fiable de matières inorganiques ou céramiques illustrées par des exemples utilisant des échantillons de polyphosphate de calcium poreux à utiliser pour former de nouveaux implants dans des applications de liaison osseuses. La clé de la définition retenue du processus a été la détermination des facteurs affectant la température de cristallisation des poudres qui sont frittées par gravité pour former des échantillons poreux d'une densité voulue et ayant une gamme de grosseurs de pores adaptée à l'application particulière. Le procédé consiste à appliquer une procédure de frittage à une poudre inorganique amorphe tassée qui donne une maîtrise de la densification et consiste à choisir des températures et des temps de frittage séquentiellement qui correspondent à la matière inorganique amorphe, mais présentant une viscosité de nature à développer des cols de frittage significatifs entre des particules de poudre adjacentes par un mécanisme de frittage à flux visqueux, tout en maintenant une structure à pores ouverts voulue, suivies d'une seconde température à laquelle la cristallisation de la poudre inorganique amorphe tassée a lieu et pendant laquelle des mécanismes associés à une diffusion plus lente gèrent la croissance et la densification de cols de frittage pour obtenir une structure inorganique poreuse sensiblement cristalline. De plus, des composites à phases d'interpénétration de polymères organiques biodégradables, dans tous les échantillons de polyphosphate de calcium poreux, ont été formés et ont eu pour résultat le développement de nouveaux composites ayant une résistance et une ténacité avantageuses. Ces matériaux tiennent leur promesse quant à la formation d'implants biodégradables de fixation de fractures et de systèmes d'ancrage dégradables pour la stabilisation temporaire d'implants d'interface osseuse conçus pour la fixation par croissance par interposition osseuse.

Inventor: CIOCCI MICHAEL
IPC: C12N5/078
Filed: 2003-07-23
Abstract: Methods, apparatus and compositions for separating a desired or undesired population or subpopulation from a biological sample are disclosed herein. The selection procedure is based on ferromagnetic, dense particles in a preferred size range from about 0.8 to about 1.2 microns. Specific binding agents are bound to the particles that recognize and bind to specific molecules on the targeted population or subpopulation, and the particles are mixed with the sample in such a way as to promote movement of the particles relative to the sample, promoting binding to the targeted population or subpopulation without non-specifically binding to non-targeted populations in the sample. Because of the large particle density, the bound population is separated from the fluid sample by gravity. Alternatively, the sample, including the bound, targeted population, is placed in a magnetic field such that the particles separate from the sample by evenly distributing over the vessel wall thus limiting non-specific trapping of the non~targeted population.
