IPC: C21C1/02
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To effectively give heat to molten iron and to improve dephosphorizing efficiency by blowing gaseous oxygen together with CaO flux at the time of dephosphorization in a molten iron ladle. SOLUTION: An injection lance R to be immersed into the molten iron P in a molten iron ladle PL is made a double tube structure and plural nozzles N2 are arranged at the peripheral part of the tip side and CaO-based dephosphorizing flux is blown while using gaseous oxygen from an inner tube and N2 gas from an outer tube.

Title: Back frame structure for back seat of vehicle
Inventor: MITSUI YOKO
IPC: A47C7/40
Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To provide a novel back frame structure for vehicle's back seats which absorbs the crash energy exerted backward with respect to the vehicle by collision of the passenger at the time of collision at the back of the vehicle so that bend breakdown does not occur. SOLUTION: Since the upper side of a back frame 1 for the seat forms a box structure with a connecting member (or tube 2), a load of the passenger which is supported by the connecting member acts on the vertical portions 1a of the frame. Therefore, the passenger is normally supported by the whole frame and kept in a safe and comfortably-seated position where the line of sight of the passenger runs parallel with the ground. If collision occurs at the back of the vehicle, a crash load due to the inertial motion of the passenger deforms each energy absorbing portion (flat tube portion 2a), which absorbs the crash load in the direction toward the back of the vehicle. This in turn reduces the crash load imposed on the right and left vertical frame portions 1a and prevents bend breakdown of the vertical frame 1a.

Filed: 1993-08-26
Abstract: PURPOSE:To lessen a semiconductor device in junction leakage caused by crystal defects by a method wherein crystal defects are taken in a diffusion layer of certain conductivity opposite to that of a substrate. CONSTITUTION:A field oxide film 4 is formed on a P-type substrate 1 through a LOCOS method and turned thin by etching. By this setup, crystal defect 5 produced under the bird's beak of the field oxide film 4 is brought adjacent to the end of the field oxide film 4 as near as possible.
