This alloying sheet has good workability, weldability, and corrosion resistance.

Title: Making method of co2 welding rod
Inventor: CHOE IN-SOP
IPC: C21C7/06
Filed: 1993-12-14
Granted: 1995-10-17
Abstract: The method comprises a step of putting Fe-Si and Fe-Mn in the ladle and degassing to produce molten steel containing 0.05-0.09 wt.% C, 0.8-1.0 wt.% Si, 1.4-1.6 wt.% Mn, below 0.020 wt.% P, below 0.020 wt.% S, etc., a step of adding CaO-SiO2 flux for the slag to have CaO/SiO2 1.0-1.4wt%, SiO2/Al2O3 over 2.0%, T.Fe below 1.0%, Al2O3 below 15%, and a step of casting in continuous billet casting machine

Title: Fruit classification apparatus
Inventor: KIM BONG-SUK
IPC: B07B13/18
Filed: 1993-12-24
Granted: 1997-04-02
Abstract: Fruits placed on a scale(3) is dropped and put into a fruit box. Up to the 90% of the objective weight, both main conveyer belt(110) and auxiliary conveyor belt(120) are operated at the same time and more fruits are processed continuously. When it comes to 90%, the main conveyor belt is stopped and the auxiliary conveyor belt only operates in one line. In this way after 90% of the object amount is completed, fruits are dropped to be filled in one row, which assures the accurate detection measurement of the 100% point. When it comes to 100% point, the auxiliary conveyer belt is stopped, and you need not stop the fruits with your hand.
