摘要:
A billet for a thixocasting process and a thixocasting process using the billet allows casting using a thixocasting process to be realized at low production cost without permeation of an oxide film to the inside of the billet in injection molding. In a billet used for a thixocasting process continuously cast by intermittently drawing out, the interval of the oscillation marks is 10 mm or less and the maximum tilt angle of the oscillation marks relative to a cross section which is at a right angle to the drawing out direction is 45° or less.

Disclosed is an apparatus for and a method of thixocasting a cast iron, that can effectively prevent the scale from mixing in the die (cavity) thereby to obtain sound iron castings having good mechanical properties. The apparatus includes at least a pair of dies that can freely opened and closed to define a cavity to be filled under a pressure, and an injector that injects the semi-molten iron into the cavity through a hole in a gate at the entry of the cavity so as to throttle the entry. The gate is a separate member disposed at the entry of the cavity every time an injection casting operation is carried out and is taken out together with the casting after the injection casting operation.

An injection mold for casting a semi-solidified Fe alloy includes a scalping gate for eliminating surface oxide film of a semi-solidified Fe alloy injected into the mold cavity from a pressure chamber. The scalping gate is arranged between the pressure chamber and a runner that is in communication with the mold cavity. The mold halves and the scalping gate are each formed of a copper alloy having a thermal conductivity of not less than 120 W/(m·K) and a hardness of not less than 180 HB. The mold halves and the scalping gate each have a cermet layer consisting essentially of at least one member selected from a group consisting of Co, Cu, Cr and Ni. The cermet layer is formed by electro-spark deposition, via an intermediate layer of Ni alloy, which is also formed by electro-spark deposition.

Purified immunocytes were analyzed for expression frequencies, and the NKIR gene expressed specifically in natural killer (NK) cells was successfully identified. The NKIR gene encodes a receptor. Agonists and antagonists for the receptor can be identified by using the receptor.
摘要:
IgM can be obtained in the form of a pentamer by placing the genes encoding the H, L, and J chains on the same vector to transform appropriate host cells. The gene encoding the J chain may be introduced by co-transfection. When no J chain is expressed, the IgM is produced as a hexamer. The transformants obtained according to the present invention achieve a high yield of IgM. The present invention also provides methods which enable separation and quantification of polymeric IgM.

The present invention relates to humanized antibodies binding to CD47; diabodies binding to human CD47, characterized in that a disulfide bond exists between diabody-forming fragments; genes encoding any one of said antibodies; vectors containing said genes; host cells containing said vectors; processes for preparing antibodies comprising the step of culturing said host cells; and therapeutic agents for hematological disorders comprising said antibodies.
摘要:
An objective of the present invention is to facilitate the acquisition of antibody-producing cells that are infiltrating virus-infected cells, cancer cells, abnormal cells forming a benign hyperplasia, and the like, and to improve the efficiency of the production of antibodies as well as nucleic acids encoding them from the antibody-producing cells.The present inventors discovered that, when cancer tissues comprising infiltrating lymphocytes are transplanted into highly immunodeficient animals that do not have T cells, B cells, and NK cells and further exhibit a low IFN production ability, the differentiation and proliferation of infiltrating lymphocytes are unexpectedly promoted, and the number of plasma cells that produce antibodies recognizing cancer tissues increases dramatically, plasma cells can be separated easily, and antibodies or nucleic acids encoding them can be easily prepared from the plasma cells.
