Filed: 1981-05-18
Abstract: PURPOSE:To provide a titled molding flask which can be applied on any thickness of the side walls of the molding flask for casting of shapeless refractories for a molten metal vessel by dividing said molding flask in a vertical direction, making the respective divided parts freely expandable and contractable to and from each other and closing the outside end opening parts between the divided parts hermetically. CONSTITUTION:The above-described split molding flask 9 is divided equally vertically, for example, is quadrisected to split parts 9'-9''''. These split parts are made expandable or contractable respectively independently to the outer side by means of elongating and contracting mechanisms, for example, oil hydraulic cylinders 10, whereby the molding flask 9 consisting of arbitrary diameters can be prepared. Covers 12 are provided in order to prevent the inflow of the cast shapeless refractories in the opening parts 11, 11' of the outside end in the spacings produced between the respective split parts when the parts 9'- 9'''' are expanded outward. As a result it is possible to apply the shapleless refractories by casting on the side wall lining and side wall protecting walls to to arbitrary thicknesses with one set of the flask 9 and therefore there is no need for preparing sets of the frames in the application.

Inventor: RIN KEIKO
IPC: G01N21/3563
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To secure the BPSG reference specimen setting value capable of correcting the precise setting value, by a method wherein a BPSG film is evaporated on a semiconductor substrate to perform the annealing step for removing the wafer content contained in the film, furthermore a shielding film averting the contact between the BPSG film and the water content existent outside the film is also evaporated on the upper part of the BPSG film.

Next, annealing is performed to remove a bit of the water content contained in the evaporated BPSG film 12 for avoiding the reaction of the contained water to boron and phosphorus in the BPSG film 12. Next, in order to cut off the contact between the BPSG film 12 and the water content existent outside the film 12 as well as the infiltration into the BPSG film 12, a shielding film 14 is evaporated. At this time, it is recommended that the shielding film 14 is formed by evaporating an oxide film evaporated by plasma process. Through these procedures, a precise concentration value as a reference can be secured in case of correcting the setting up value of a concentration measuring instrument.
