Abstract: A top-blowing lance nozzle is configured to freely switch an adequate expansion condition so as to control an oxygen-blowing amount and a jetting velocity independently of each other without requiring a plurality of lance nozzles or a mechanically movable part. A lance nozzle is configured to blow refining oxygen to molten iron charged in a reaction vessel while a gas is blown from a top-blowing lance to the molten iron. One or more blowing holes for blowing a working gas are on an inner wall side surface of the nozzle, at a site where the lance nozzle has a minimum cross-sectional area in a nozzle axis direction or at a neighboring site of the site.

Abstract: Provided is a novel heterocyclic compound having an aryl hydrocarbon receptor antagonist activity and useful for the promotion of platelet production, the compound being represented by the general formula [I]: wherein ring A, ring B, R1, R2, R3, R4, n, and X are as defined above, or a salt thereof.

Abstract: According to a conventional method, there is only one kind of a database access screen pattern (single sheet format), the screen layout cannot be changed from one user to another, a portion that produces an output to a database needs to make an external program call, and, there is no user-by-user utilization right which is generally required for a database access screen, not is there a function provided for transitioning from database access screen A to database access screen B involving value transfer. The present invention is provided with two kinds of screen patterns of a single sheet format and a list format, eliminates the need for a programming language and a database operation language, and is further provided with user-by-user utilization right and a function for transitioning from data access screen A to data access screen involving value transfer on the basis of a setting made by a setting person without requiring programming.
