Title: Electrical junction box
Inventor: YOSHIDA NORIYUKI
IPC: H02G3/14
Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To provide an electrical junction box with a cover which can be attached and detached easily. SOLUTION: Water-proof ribs 8 whose spacing is widened against the insertion direction of a protective wall 10 formed integrally on a cover 3 are formed on both the sides of a recess 7, which is formed in order to fix a terminal 15 to the bus-bar 9 of a fusible link 11 with a screw 16. As the spacing between the water-proof ribs 8 on the insertion side is wider than the width of the tip part of the protective wall 10, the protective wall 10 can be inserted easily. Further, in order to remove the cover 3 from a junction box main part 2, if the protective wall 10 is shifted even only a very little from the assembled position, sufficiently large gaps can be formed between the protective wall 10 and the water-proof ribs 8, so that the cover 3 can be removed easily.

Filed: 1985-07-02
Abstract: PURPOSE:To efficiently dephosphorize molten pig iron by adding quick lime to slag rising to the surface of the molten pig iron after desiliconization to properly adjust the basicity of the slag and by adding quick lime and oxygen to the molten pig iron. CONSTITUTION:When molten pig iron desiliconized to <=0.2% Si content is dephosphorized by adding quick lime and oxygen, quick lime is added beforehand to desiliconization slag remaining and rising to the surface of the molten pig iron after the desiliconization to adjust the basicity (weight ratio of CaO/ SiO2) of the slag to >=2.0. Phosphorus in the molten pig iron is then converted into phosphorus oxide by oxidation with oxygen, fixed with quick lime and maintained stably in the slag to prevent rephosphorization.
