Title: Device for collating fingerprint
Inventor: KAMIYA TOSHIHARU
IPC: G06K9/00
Filed: 1987-05-08
Abstract: PURPOSE:To highly accurately collate a fingerprint by updating the registered data of feature point groups based on the feature point extracted from a fingerprint picture inputted at the time of collating. CONSTITUTION:The feature point groups to be extracted from the inputted fingerprint picture when it is decided that the collation coincides at the time of inputting the fingerprint are accumulated and stored in a second storing means 15. Accordingly, based on the feature point groups stored in the means 15, the history of the change of the input feature point groups can be decided. The feature point groups selected correspondingly to this history are used as the registered feature point groups, stored and set to a first storing means 14 as the registered data when the coincidence of the collation of the inputted feature point groups is decided. Then, in the means 14, the registered data in which the input feature point at the time of the latent collation is defined to be a reference is constantly updated and set. Based on this registered data, a collating operation is executed and the collation of the fingerprint of high accuracy is executed.

Title: Reinforcing method of existing building
Inventor: SUZUKI HIROMI
IPC: E02D31/00
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To secure safety at earthquake even when the ground directly under a building is digged by constructing an underground wall on the outer periphery of the building, and providing a horizontal plane member capable of transmitting horizontal force and compression force therebetween. SOLUTION: After constructing an underground wall 2 in the condition of surrounding an existing building 1, the ground between the underground wall 2 and the building 1 is drilled. After drilling, a plane member 3 is horizontally interposed between the underground wall 2 and the building 1, and it is fixed by the use of bolts and nuts. Hereat, when the space between the underground wall 2 and the building 1 is wide, a slab 6 is projected, a pane member 3 is interposed between the extreme end of the slab 6 and the building 1, or the slab 6 is projected from the building 1 side toward the underground wall 2 side, and the plane member 3 is interposed between both slabs.  Because the existing building 1 is surrounded with the plane member 3 on the nearly whole periphery, at earthquake, almost horizontal force and compression force generated by shake of the building 1 can be transmitted to the peripheral underground wall 2.

Abstract: PURPOSE:To attain the optimum smoothing processing in response to a curvature of a contour and to implement optimum smoothing processing in response to kind of toner and resolution by detecting the contour of a picture closer to a horizontal line or a vertical line in an information recording device such as a laser beam printer. CONSTITUTION:A binary data VDO expanded into a dot pattern is stored sequentially in line memories 1-9. A processing circuit 43 consists of a logic arithmetic circuit to discriminate whether the data is a contour of a picture or an intermediate tone picture based on the data of 11X9 picture elements in shift registers 34-42. When the data is discriminated to be a contour of a picture, the data of a noted picture element is changed so that the contour is smoothly printed out. A revised data VDOM is converted again in response to the kind of toner or the like. The converted signal is sent to a laser driver of a printer engine and printing is implemented by the scanning of the laser.

Abstract: PURPOSE:To prevent effectively missing of stored data due to noise by using a content of an address register as an address of a dummy memory area at a non-access period of the memory. CONSTITUTION:In accessing a memory 1, a signal processing circuit 7 sets an address representing the said memory area to a register 3 and sets the data to a register 4 for access. Then after the address of a memory area MAD of the dummy is set to the register 3, a series of access operations are finished. In this case, the dummy area MAD is addressed at the non-access period. Thus, even when noise comes during the non-access period, only the storage content of the area MAD is lost and data in effective memory area MA1-MAN are not lost.

SOLUTION: This steel material is the one applying the working of rolling, etc., after heating a cast slab, in which >=100 pieces/cm2 of the inclusion having <=6% lattice coherency with the δ-ferrite formed at the solidifying time from the molten steel is contained. Since this steel material works the cast slab having uniform and fine solidified structure, the surface and internal defects thereof caused by the solidified structure are reduced, and this cast slab is easily deformed in the rolling reduction direction and the workability of rolling, etc., can be improved. Further, the surface defects of slab, crack, etc., and the surface and internal defect of porosity, center segregation, etc., generated in the steel material after working can be restrained.

An alkali such as slaked lime is further added to separation-recover the iron salt catalyst as ferric hydroxide sludge. Since this sludge contains no org. partially oxidized product and is harmless, it is thoroughly dissolved in a mineral acid such as sulfuric acid at pH≤2 and the soln. is reused as the flocculant of the  first process at pH≥3.

Abstract: PURPOSE:To eliminate after image by bringing a level of a left charge elimination electrode having been at an H level into an L level for a read period when a read pulse is applied to the read electrode so as to read the charge stored in the photoelectric conversion element to a CCD without leaving any charge. CONSTITUTION:Part of the stored charge is left under a left charge elimination electrode 10 and a read electrode 5 in a photoelectric conversion element for a period (shown in figure (c)) when a read pulse is applied to the read electrode 5 and most of the stored charge 11 is read to the CCD. Figure (d) shows the state that the left charge elimination electrode goes to a low level. In this case, when the L level of the left charge elimination electrode is lower than the level of the read pulse, the left charge 9 is read to the CCD to eliminate the left charge and the after-image. Moreover, when the surface of the photoelectric conversion element under the left charge elimination electrode 10 is n-region, the charge generated due to thermal excitation in the surface level is prevented by applying the level at which the surface of the photoelectric conversion element is pinched off as the L level to the left charge elimination electrode.
