Title: Blowing device for bottom blowing gas in ladle for molten metal
Inventor: ARAMAKI KEIZO
IPC: B22D1/00
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To repeatedly use a plug for bottom blowing gas in a ladle. SOLUTION: An accumulating tank 11a providing a nonreturn valve 12 is arranged in parallel with a gas supplying pipe 3 feeding the bottom blowing gas into the porous plug 2 arranged at the bottom of the ladle 1. Before refining, the gas is stored into the accumulating tank 11a and during refining, the bottom blowing gas is fed through the gas supplying pipe 3 to stir molten metal in the ladle 1. After refining, a stop valve 4 in the gas supplying pipe 3 is closed and a switch valve 4a for the accumulating tank 11a is opened, and a little quantity of the bottom blowing gas is continued to supply and cut off from gas supplying source 6 with a coupler 5.  During shifting the ladle and after this operation, the penetration of the molten metal into the plug is prevented with the bottom blowing gas from the accumulating tank, and since the plug is not clogged with the metal, this plug can repeatedly be used.

Title: Correction for defective bit of dram using system
Inventor: FURUTA MINORU
IPC: G11C29/42
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To relieve a DRAM being eliminated as a defective product at present by using a DRAM having a defective bit or a memory module including a DRAM having a defective bit in a system in which an error is detected and corrected by utilizing algorithm of Error Checking and Correcting(ECC). SOLUTION: A dram module having bit width of 72 bits is prepared by using a DRAM including a defective bit being not in the same address even if defective bits of two bits or more exist in a DRAM. When this DRAM module is used for a system requiring data width of 64 bits, such ECC code can be produced that 8 bits is redundant bits, an error of 1 bit is detected and can be corrected, an error of 2 bits can be detected, but cannot be detected. Thereby, when this DRAM module is used for a system applying algorithm of ECC, all defective bits are corrected, and a system is operated normally.

Title: Device for preventing bounding of diaphragm vane
Inventor: NOMURA HIROSHI
IPC: G03B9/07
Filed: 1983-10-08
Abstract: PURPOSE:To prevent bounding of a diaphragm vane with a simple construction by converting the repulsive rotating energy of collision generated when an open/ shut ring collides against a member for restricting the angle of rotation to the rotating energy of a braking member which is energized to rotate in the same direction as the rotating direction of the open/shut ring. CONSTITUTION:When a sutter button is pushed, an open/shut ring 16 is rotated toward an arrow B by the force of a tension spring 2 and a pin 18 for regulating aperture diameter collides against a surface 20 for regulating the angle of rotation. A braking ring 25 is rotated by the force of a tension spring 27 cooperatively in the same direction as the rotating direction of the ring 16. When the pin 18, i.e., the ring 16 collides against the surface 20, the ring is to rotate in the direction opposite from the direction before the collision by the rotating energy held by the ring prior to the collision but the repulsive rotating energy of collision generated in the ring 16 is mostly converted to the rotating motion overcoming the force of the spring 27 of the ring 25 and therefore bounding of the ring 16 is obviated.
