Inventor: ARAMAKI TAKASHI
IPC: G06T7/00
Filed: 1995-05-23
Abstract: PURPOSE: To reduce the complexity by enabling discrimination without touching a device. CONSTITUTION: Information obtained by a collation range determining means 1 and a center determining means 2 is taken over by a feature point processing means 3, a raster scan on only the face part of an image after an undetermined part is moved and an outline part is found is made, and pixels are classified and counted by pixel values. Further, data which are classified into 256 stages are grouped into 20 stages. At this time, the right and left half parts of the face are counted individually according to the coordinates of a center line calculated by a center determining means 2. There is little possibility that the right and left of the face of a person is exactly the same and collation is performed on the basis of data obtained in consideration of natural features.  Feature points which are thus obtained are (1) variance in the number of pixels among the groups in a half face surface, (2) variance in the number of pixels between each of the half face parts in the same group, and (3) variance in the number of pixels between the right and left parts of the whole face.

Abstract: PURPOSE:To decrease the amt. of an inert gas for pressure equalization to be used condiderably and to reduce iron making costs in a blast furnace to be operated under high  pressure by utilizing the high pressure of a blast furnace waste gas in the pressure equalizing operation for a pressure equalizing chamber. CONSTITUTION:The high pressure waste gas from the inside of a blast furnace 7 to be  operated under high pressure is supplied through pipings 8a, 8b into a dust catcher 9  and a ring slit washer 10 by which the gas is purified. The purified gas is utilized for  power generation for the furnace top. In this case, part of the purified gas from the  washer 10 is introduced into an upper bell hopper (pressure equalizing chamber) 3 of  the blast furnace to equalize the pressure therein primarily. Since the pressure of the  purified gas in this time is made lower than the furnace top pressure by the catcher 9  and the washer 10, the half purified gas under high pressure removed from the intermediate part of the washer 10 is introduced into the chamber 3 to equalize the pressure  secondarily. Finally, a small amt. of an inert gas such as N2 is introduced to equalize  the pressure in the chamber 3 with the pressure in the furnace inside 7. The amt. of  the inert gas to be used is decreased and the iron making costs are reduced.

Abstract: PURPOSE:To obtain an electrically stable PSG film covering a stepped section satisfactorily by exciting and activating PH3 gas more than other gas wherein the bonding with P and O2 is attempted. CONSTITUTION:A suspector 6 is installed in a bell jar 5 and a wafer 4 is placed on the susceptor 6 for heating by a heater 7. SiH4 and N2O are poured from a pipe- shaped shower 8. A high-frequency voltage is applied across the shower 8 and the susceptor 6 and plasma is excited to activate SiH4, N2O or the like. A high-frequency current flows into coils 11 at the upper part of the jar 5 to excite the plasma and induced 10 PH3 is activated. Furthermore, the PH3 again passes through a plasma region at the upper part of the wafer 4 and the PH3 is completely activated. As a result, the sufficient bonding with P and O2 follows to produce SiO2.P2O5. This film satisfactorily covers a stepped section and has low dielectric constant. Chemical resistance will also be improved by maintaining the P concentration of the surface layer at 1mol in percent or below.
