Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To provide a melting method by which the energy for heating and melting cold iron raw material in an arc furnace is efficiently supplied to the cold iron raw material. SOLUTION: The whole quantity or a part of the cold iron raw material for one heat is charged into the arc furnace and oxygen is supplied from an auxiliary combustion device and heated and successively, the electric power is supplied to heat and melt the cold iron raw material. At this time, the oxygen feeding quantity before starting the supply of the electric power is controlled to 3-10 Nm3/t-cold iron. Such an operation is adopted for the heat where the total oxygen feeding quantity per one heat is >=25 Nm3/t-molten steel. As for the furnace body shape, the relation between the height L from the bath surface in the furnace at the time of melting the whole iron source raw material to the upper end of side wall in the furnace and the inner diameter D in the furnace satisfies L/D=0.6-1.4.  The heat conductive efficiency is improved to enhance operability and reduce cost without requiring the special apparatus for preheating the scrap and the special device for charging the scrap.

Title: Method for reproducing image
Inventor: OKABE MASAHITO
IPC: G02B3/06
Filed: 1996-10-14
Abstract: PROBLEM TO BE SOLVED: To obtain the gradation of a reproduced image extending over a high exposure area from a low exposure area by detecting the transmissivity of a pixel corresponding to the central part of a microlens, deciding which area out of the high exposure area, the low exposure area or a middle area between them the detected transmissivity is set and changing the range of the pixels fetched in order to produce reproducing data according to the exposure area. SOLUTION: On a characteristic curve L1 obtained when the data of one pixel of the center of the microlens is regarded as the data of the pixel, gradation is obtained in the lower exposure area but it is not expressed from half tone because liquid crystal is oriented extending over the high exposure area-On a characteristic curve L2 obtained when not only the pixel of the central part but also the pixels of a peripheral part are averaged and regarded as the data of the pixels, the reproducibility of the gradation from the half tone in the high exposure area is enhanced but the gradation is not reproduced in the low exposure area. On a characteristic curve L3 obtained when the number of pixles for sampling the data is increased toward the peripheral part, the gradient in the high exposure area is more enhanced.  By dividing the exposure area to the high, the middle and the low areas and selecting the excellent data, the excellent reproducibility of the gradation is obtained.
