Title: Method for designing authentication system and digital signature system
Inventor: HANEDA TOMOSHI
IPC: H04L9/32
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To make it possible to check the safety of even the authentication protocol which is heretofore unsable and to use the same by verifying whether the communication contents of the formed authentication protocol and another authentication protocol are metrically identifiable or not. SOLUTION: The authentication protocol of the unknown safety is selected (S11) and thereafter, two bit commitment protocols are selected (S12). The authentication protocol is corrected by using the selected bit commitments (S13) and the safety of the corrected protocol is verified (S14). If the verification of the safely of the corrected protocol is successful, the authentication protocol is completed as the safe authentication protocol and further this protocol is packaged in the authentication system. In case of a failure in the safety verification of the corrected protocol, the other two bit commitment protocols are selected and the verification of the safety is executed by correcting the authentication protocol by using the same. The safe authentication protocol is finally obtd. by repeating the processing described above.

Title: Production of stainless steel fiber
Inventor: ITO KENJI
IPC: B21F19/00
Filed: 1984-12-10
Abstract: PURPOSE:To manufacture good-quality stainlesss steel fiber by putting the bundle of stainlesss steel wires coated with a dead soft steel strip having a specific carbon content or below into a steel pipe of the carbon content lower than the carbon content of the stainlesss steel wires, hot rolling the steel pipe and removing the carbon steel by a chemical treatment after repetition of cold drawing and annealing. CONSTITUTION:The stainlesss steel wires are coated with the dead soft steel strip having <=0.008w% carbon content by using a single head drawing machine or die machine. Such coated wire bundle is inserted into the steel pipe of the carbon content lower than the carbon content of the stainlesss steel wires and is hot rolled. The steel pipe is thereafter subjected repeatedly to cold drawing and annealing and the carbon steel is removed by the known chemical treatment, by which the stainlesss steel fibers are obtd. The carbon content of the coating steel strip is extremely low and the carbon content of the outside cylinder is low as well and therefore the carbon content of not only the central wires of the bundle but also the outside peripheral wires is decreased to the specified carbon content or below by the synergistic effect even if the intrusion of carbon arises in hot rolling and annealing. The quality is much improved if Ti and Nb having the higher affinity to carbon than Cr are incorporated into the stainlesss steel wires.

Title: Device for detecting defect of surface
Inventor: ISHII HIROYUKI
IPC: G01B11/30
Filed: 1989-10-06
Abstract: PURPOSE:To remove the ring part of a work and the ruggedness of a textured surface as a noise from an image for identification by illuminating the surface of the work from different directions and performing image processing by the logical operation of the change of binary signal to a picture element output before and after changing an irradiating position concerning a non-plane part where there is the difference of height. CONSTITUTION:A video output from a CCD camera 3 is converted to a binary image in a pre-processing part 6. The binary image whose picture element output exceeds a fixed value, for example, is displayed as a white image and the binary image whose picture element output does not satisfy the fixed value is displayed as a black image. At the stage of the conversion of binarization, both of a part which is along the side of the work on an illumination side and a fine projecting part on the surface of the work other than a defective part in right and left illuminated images are displayed as a white pattern in a black texture. Meanwhile, since the part other than the defective part is removed as the noise by the logical operation by a CPU 7, only defective part nearly remains as the white pattern in the image after the conversion. The area of the white pattern is measured by an identification part 8 and compared with a reference value. Then, the propriety is finally decided based on whether the measured value exceeds the reference value.

Filed: 1989-10-06
Abstract: PURPOSE:To maintain the condition of measurement having high accuracy and a high measuring speed by simultaneously using a cushioning member at the lower end of an approach bar with an optical measuring device provided with an air supply pipe. CONSTITUTION:When a stylus 6 and the approach bar 4 are positioned just above a measuring point P2, pressurized air is introduced into an air cylinder 16 through the air supply line 2. Since the dimensional items of component members are set so that pressured area 4A of the approach bar 4 may be larger than the pressured area 6A of the stylus 6, the approach bar 4 starts a descending motion previous to the descending of the stylus 6 and it descends until the cushioning member 7 comes in contact with the surface to be measured 8A of a model 8. Thereafter, the stylus 6 descends and the lower end of the stylus 6 is pressed to the measuring point P2 with specified pressing force. An air pressure detector detects this state and the measurement is started by the optical measuring device 19 based on the detection.
