IPC: H04N5/57
Filed: 1994-11-28
Abstract: PURPOSE:To emphasize a luminance signal which is inferior in S/N without emphasizing a high-frequency noise by emphasizing the contrast of a low-frequency luminance signal by an LPF, putting it together with the difference between a source luminance signal and the low-frequency luminance signal, and outputting the composite signal. CONSTITUTION:The low-frequency luminance signal is separated by the LPF 10 from the input luminance signal and a contrast emphasizing circuit 12 emphasizes the contrast. This emphasized signal, and the input luminance signal and low-frequency luminance signal passed through a subtracter 11 are put together by an adder 13, and the resulting signal is outputted. This constitution emphasizes the luminance signal which is inferior in S/N while preventing the high frequency noise from being emphasized, and the resolution of an image signal can be improved.

Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of errors when fuel control is returned to air-fuel ratio control wherein a catalyst oxygen retention volume after fuel cut is kept in the maximum effective oxygen retention volume. SOLUTION: Catalyst 21 disposed to an exhaust passage holds an oxygen retention capacity. When an air-fuel ratio in exhaust gas at the downstream of the aforesaid catalyst is changed from a stoichiometric condition to a lean condition, the oxygen retention volume of the catalyst at that time is stored in a memory means 22 as the maximum effective oxygen retention volume, when an air-fuel ratio in exhaust gas at the downstream of the catalyst is found to be close to a stoichiometric condition, a value estimating an under and over oxygen volume flowing over the catalyst per specified hour, is operated as a catalyst oxygen retention volume by an operating means 23.  When a specified air-fuel ratio condition is not satisfied, and when the aforesaid air-fuel ratio is lean, a late reaction oxygen absorbing volume per specified hour, by which oxygen is slowly absorbed by the catalyst, is estimated so as to allow a catalyst oxygen retention volume exceeding the maximum effective oxygen retention volume to be operated by an operating means 24. And when a specified air-fuel ratio condition is satisfied, an air-fuel ratio shall be controlled by a control means 25 so as to allow a catalyst oxygen retention volume at that time to be within the maximum effective retention volume.

Filed: 1988-11-22
Abstract: PURPOSE:To execute smelting reduction iron making while preventing the erosion of refractories even if the upper space of a reaction vessel is kept at a high temp. by tapping the greater part of the molten iron in the reaction vessel from the lower part of the vessel, then tilting the vessel to discharge the slag at a ratio below the prescribed ratio from the top of the vessel at the time of the smelting reduction iron making by top blowing. CONSTITUTION:Iron oxide and carbonaceous material are added to the melt in the tiltable reaction reaction vessel 1 which has a tap hole 9 in the lower part and has the upper part formed of a water cooling wall 10, then O2 is top blown 5 to form the molten iron 2 and molten slag 3. The CO is oxidized to CO2 and a high temp. is attained in the upper space of the vessel 1 during this time, but the erosion of the refractories is prevented by the wall 10. the molten iron 2 is tapped 9 by 60 to 90% only at the time of tapping. After the tap hole 9 is closed, the vessel 1 is tiled to discharge <=70% of the slag 3 from the top of the vessel 1. Since the CO is sufficiently oxidized to the CO2 according to the above-mentioned method, the secondary combustion rate CO/(CO+CO2) can be maintained high. The heating up of the molten metal and molten slag is, therefore, rapid and the reduction reaction of the iron oxide is accelerated. The molten iron is thus produced with high productivity.
