Abstract: A floating separating element for use in centrifugal separation of components of a physiological fluid comprises a positioning part and a separating part, where the positioning part is designed to automatically assume a position in a supernatant and a separating part is positioned at a desired location with respect to the interface between the supernatant and heavier components. In preferred embodiments the physiological fluids are blood or bone marrow aspirate, and the heavier components comprise red blood cells. The positioning part comprises the majority of the mass of the separating element and is thin so that differences in the position of the separating element with respect to the interface are small compared to differences in the densities of the separated compoments, particularly the component comprising red blood cells. A method allows red blood cells to move the separating element during decanting to ensure complete decant of the supernatant.

The hydrating fluids may be a mixture of fluids provided in any desired proportion. The hydrated material is then ejected from the container.

Abstract: To effectively impart sizing performance to paper, while reducing the amounts of an internal sizing agent and aluminum sulfate, a papermaking additive comprises a mixture of an amphoteric copolymer having a hydrophobic group whose quaternization ratio is 40% by mole or more, and in which the ratio of the anion equivalent to the cation equivalent is 0.1 to 90%, and a calcium carbonate filler. The filler is one in which suitable water repellency is imparted to the filler. Hence, by adding this to pulp slurry, followed by a wet papermaking, the filler is efficiently adsorbed onto pulp fibers having anionic property, so that effective sizing performance can be imparted to the paper by using a smaller amount thereof than the internal sizing agent, while reducing the amounts of the internal sizing agent and the aluminum sulfate.

Abstract: The invention at hand describes Cu-(II)-oxygen adduct complexes, which are stable at room temperature, as well as methods for their production. In this, compounds of the general formula [L-Cu—O—O—Cu-L](BAr4)2 are concerned. Here, BAr4? is a tetraarylborate anion, selected from tetraphenylborate and tetrakis(3,5-trifluoromethyl)phenylborate. L represents a tripodal tetradentate ligand, wherein, each of the four binding sites of the tripodal tetradentate ligand is a nitrogen atom. Each of the three podal ligands is suitable for comprising an aliphatic amine or a nitrogen-containing heteroaromatic compound independently of one another. A bridge of one to four carbon atoms is located between the central nitrogen atom and the nitrogen atom of each of the podal ligands. The Cu-(II)-oxygen adduct complexes according to the present invention are produced, by initially reacting the ligand L with a Cu-(I) salt to [Cu-L]X.

Abstract: A plug 2 used for a piercer according to the invention includes a tip end portion 23, a cylindrical portion 24, a barrel portion 25, a mandrel coupling portion 22, and an injection hole 21. The injection hole 21 penetrates from the surface of the cylindrical portion 24 to the surface of the mandrel coupling portion 22 and an externally supplied lubricant is injected from the hole. A clearance forms between the pierced material and the cylindrical portion 24. The injection hole 21 is formed at the cylindrical portion 24, and therefore the material in the process of piercing does not contact the injection hole 21. Therefore, an inner surface defect attributable to the contact between the material and the injection hole 21 can be prevented from being generated.

Abstract: When a hollow billet is inserted into a container, and hot expanding piercing is downwardly performed by using a plug, hot piercing is performed by using a formed glass complex comprising a ring-shaped formed glass part and a ring-shaped projecting part. The ring-shaped formed glass part assumes a disc shape having a circular opening for allowing a plug to be inserted at the center thereof. The ring-shaped projecting part is attached to the opening of the ring-shaped formed glass part, and assumes a ring shape projecting perpendicularly to the ring-shaped formed glass part. Thereby, the piercing work can be done safely, and defects can be prevented from occurring on the inner surface of the billet.

Abstract: A product intermittently having a bent portion which curves three-dimensionally and a quenched portion is manufactured by performing bending downstream of a support means while feeding a metal material which is supported by the support means from an upstream side towards a downstream side. A portion of the metal material is heated by a heating means downstream of the support means. A bending moment is imparted to the portion of the metal material heated by the heating means to three-dimensionally change the position of a movable roller die which is disposed downstream of the heating means and has a plurality of rolls which feed the heated metal material in the axial direction, and the metal material is quenched by spraying a cooling medium at the portion of the metal material which was heated by a cooling means disposed between the heating means and the movable roller die.

Abstract: A whole determination area of a targeted wafer is concentrically divided in a radial direction, COP density is obtained in each divided determination segment, a maximum value of the COP density is set as COP densityRADIUSMAX, a minimum value of the COP density is set as COP densityRADIUSMIN, a value computed by “(COP densityRADIUSMAX?COP densityRADIUSMIN)/COP densityRADIUSMAX” is compared to a predetermined set value, and a non-crystal-induced COP and a crystal-induced COP are distinguished from each other based on a clear criterion, thereby determining the COP generation factor. Therefore, a rejected wafer in which a determination of the crystal-induced COP is made despite being the non-crystal-induced COP can be relieved, so that a wafer production yield can be enhanced.
