Abstract: PURPOSE:To produce a molten iron from iron ore with high thermal efficiency by preheating the powdery iron ore with the exhaust gas from a top blowing converter type refining furnace, then preheating and prereducing the ore further with a prereduction furnace and charging the iron into the refining furnace at the time of reducing the iron ore with carbonaceous material by using the above-mentioned refining furnace, thereby executing iron making and refining. CONSTITUTION:The lumped iron ore, carbonaceous material and slag forming material are charged by a chute 14 into the converter type refining furnace 10 provided with a top blowing lance 21 and side face and bottom tuyeres 25, 26. Gaseous O2 is blown from the nozzle 22 of the lance 21 to burn the carbonaceous material and to smelt and reduce the raw materials, by which the molten iron 11 and molten slag 12 are formed.

Title: Functionally gradient copper material and its manufacture
Inventor: TAJIRI KEISUKE
IPC: C25D1/00
Filed: 1990-11-28
Abstract: PURPOSE:To manufacture a functionally gradient copper material by controlling the ion concn. of an electrocasting bath. CONSTITUTION:The metallic structure, i.e., mechanical properties of copper to be precipitated are changed by electrocasting conditions. At the time of executing electrocasting while polarity is reversed in an acid copper sulfate bath not contg. an organic addition agent, the mechanical properties of electrocast copper are decided depending on whether the metallic structure is formed into a columnar one or an acicular one. Namely, at the time of increasing the chlorine ion concn. in an electrocasting soln., the structure changes from an acicular one into a columnar one to increase its elongation and to deteriorate its strength. By controlling the chlorine ion concn. in the electrocasting bath, its manufacture can easily be executed, and, because high temp. heat is not given to a substrate like the case of brazing and diffusion welding, annealing and recrystallization are not generated in the substrate. Namely, by this invention, the copper material combining the best elongation and the best strength can be obtd.

Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To effectively suppress power consumption at providing of a buffer amplifier for each line in an image sensor for disposing photoelectric conversion elements by plural pixel units in a matrix shape and successively reading the pixel information of the respective photoelectric conversion elements in the selected line, while selecting the line in a row direction. SOLUTION: A dedicated power source for driving the buffer amplifier BF provided for each line of this image sensor is provided through a control switch 4, and only at the time of reading the pixel information from the respective lines, the control switch 4 is turned on, and power is supplied to the buffer amplifier BF. The time required for reading the pixel information from the respective photoelectric conversion elements is considerably shorter (about one pat in several tens of minutes) than the storage time of the pixel information, and no disturbance occurs even when the power is not supplied to the buffer amplifier BF during the period in which there is no reading of the pixel information. Thus, by stopping the supply of the power to the buffer amplifier BF other than the time of reading the pixel information from the respective lines, the total power consumption is reduced.

IPC: H04N1/21
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To provide a data transfer device which can speed up data transfer and reduce the load on a CPU. SOLUTION: Image data outputted from a control part 303 are inputted to an image compression part 305. The image compression part 305 while compressing the data outputs the compression result to a HD controller 306 in real time. The internal bus of the HD controller 306 is set to a route (1). A CPU circuit part 205 issues a command for data transfer to a hard disk 207 through the HD controller 306. When the hard disk 307 becomes ready for data transfer, the internal bus is switched to a route (3) and the image begins to be transferred. Consequently, the CPU in the CPU circuit part 205 is disabled to access the hard disk 207. The compressed data outputted from the image compression part 305 are inputted to a buffer part 404 and outputted to the hard disk 307 by DMA transfer.
