Title: Sill with end section
Inventor: KAMITE MASAYUKI
IPC: E06B1/70
Filed: 1994-01-13
Abstract: PURPOSE:To facilitate the execution of work by forming an end section brought into contact with the top face of a floor surface board material to a sill and preventing the viewing of the end face of the floor surface board material. CONSTITUTION:Since the front end of the underside of an end section 50 is brought into contact with the top face of a floor surface board material 30, the end face of the board material 30 is concealed. Consequently, the end face of the board material 30 need not be fast stuck on the external side face of a sill body 40 without clearances, and the end face treatment of the end-face cutting, deburring, etc., on a field is omitted. Next, the main body 40 is formed by molding a resin, with which powder prepared by beating the impalpable powder of a cellulose material is mixied, and the surface of the main body 40 displays a figured grain pattern. Further, the main body 40 is molded simply by extrusion molding, and fillers for resisting external force are placed in a hollow section 41, thus increasing strength. Accordingly, field work can be simplified while the texture of natural water can be formed, the sill body 40 can be manufactured easily, and strength can be increased.

Title: Desiliconization method of molten metal
Inventor: YAMAMOTO SATOMI
IPC: C21C5/56
Filed: 1979-01-12
Abstract: PURPOSE: To improve the yield of molten iron at the desiliconization by using the insoluble residues of the time when the slag at the oxidation refining of molten metal composed primarily of alkali metal compounds is treated with water, as the slag forming agent for desiliconization of molten metal.  
     CONSTITUTION: Desulfurization and dephosphorization refining of molten iron are accomplished by the slag using alkali metal compounds such as Na 2 CO 3 . The slag formed at this time is water soluble. It is leached by water to recover Na, etc. and is regenerated as the raw material for refining slag. Since the residues remained at this time contain Na, Fe, Mn, Si, etc., they are dried and are used as the slag for desiliconization prerefining of molten iron. This improves the fluidity of the slag, accelerates the sedimentation of the particle iron interposing in the slag into molten iron and improves the yield of molten iron.

Title: Chipless discharge tube
Inventor: YUASA KUNIO
IPC: H01J61/30
Filed: 1990-01-11
Abstract: PURPOSE:To prevent a blackening of a bulb resulting from the vacuum sealing by using a glass in which the component ratio of lead oxide is set less than a specific value for the bulb. CONSTITUTION:A glass bulb 2 is formed of a glass including PbO, the component ratio of the PbO is set less than 10wt.%, and the bulb is composed in a chipless type omitting the exhaust pipe. And after a cap 4a is fixed airtight to the bulb 2, a rare gas such as argon gas is pressed in to the bulb 2 in a vacuum ambiance, and a metal cap 4b is heated to fuse to seal up airtight. In this case, the bulb 2 is heated in a rare gas ambiance with little oxygen, and the PbO in the bulb 2 is dissolved to lead as the bulb 2 is cooled. However, since the component ratio of PbO is small, almost no blackening phenomenon in the bulb 2 is generated. Consequently, a blackening of the bulb owing to the vacuum sealing is prevented, and a high brightness can be maintained.
