Title: Hash function method
Inventor: INOUE TORU
IPC: H04L9/06
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To reduce the circuit scale by shortening the code length of a hash function device for simplifying the operations. SOLUTION: A message is encoded by being inputted to a convolutional encoding circuit. Encoded data and a hash value before one clock are inputted to a hash function unit 1 to generate a hash value. A hash value compressing the message is obtained by accumulating the hash value in a FIFO memory 3 having a capacity for several stages of a constraint length of the convolutional code. A multiple Davis-Meyer hash function unit 1 can be reduced in size down to a small block length n0 of the convolutional code by selecting an input bit length to a Davis-Meyer fundamental structure to be a small block length n0 of the convolutional code, and inputting it thereto by dividing it into N stages according to the constraint length N of the convolutional code length N.  The number of the stages of the fundamental structure of the Davis-Meyer hash function unit 1 can be reduced to 1/N of the case where the block codes are used.

Title: Vibration-resistant device of building
Inventor: OYAMA HIDEMI
IPC: E04H9/02
Filed: 1989-01-18
Abstract: PURPOSE:To keep safety of a building with its proper rigidity, by arranging shear- deformative vibration-resistant walls in which a liquid is filled or particles are changed in an almost saturated state, as repeated forces with more strength than a certain value, acting between interlayers of buildings, cause liquifying phenomema. CONSTITUTION:Shear-deformative vibration-resistant walls 1 are assembled by steel- channels made of steel treated with anti-corrosives, aluminum, stainless steel, etc., to form a hollow container by filling an elastic member 1c such as rubber or the like between respective flanges of rectangular frame 1b having rigidities reinforced with restricting members 1a against the width, when necessary. The container is filled with a liquid 2 like water within the vibration-resistant walls 1 or it is charged with glass beads or particles 3 like sand having larger grains than a certain size are charged in an almost saturated state. And a liquid auxiliary tank 4 is connected to the vibration-resistant walls 1 in order to always saturate the container with the particles 3. Next, the walls 1 is supported at upper ad lower beams 5 via pin joints 6. When a small external force like a strong wind or a middle and small scale earthquake acts on it, particles 3 within the vibration-resistant walls 1 does not liquify and acts against the external force and, hence, generates a vibtration-resistant effect.

Abstract: PURPOSE:To obviate generation of unequal densities in halftone part of image- formed even at a low temp. within a practicable use temp. range and prevent black solid part from becoming to have a lower density. CONSTITUTION:This electrostatic charging member is so formed that the resistance value between an arbor 4 of an electrostatic charging roller 2 having a resistance layer 6 on its surface and the surface of the electrostatic charging member 2 satisfies a relation of [0.3<= the resistance value after coating of the resistance layer/the resistance value before coating of the resistance layer <=10], thereby the resistance value between the arbor 4 and the resistance layer 6 on the surface of the electrostatic charging roller 2 is approximated to the resistance value between the arbor 4 and an elastic conductive layer 5. An increase in segregation of the resistance material included in the resistance layer 6 at the time of a low temp. is thus prevented and the generation of the unequal densities and the formation of the black solid part of a low density are prevented.

IPC: C08F12/00
Filed: 1985-01-21
Abstract: PURPOSE:To make possible fine working by high energy rays with less light injuries and to improve mechanical strength by using a material which is expressed by the specific formula and can be patterned. CONSTITUTION:The material expressed by the formula is used as the material for the non-linear optical element which can be patterned. The above-mentioned optical element is produced by dissolving the material for the non-linear optical element in a suitable solvent and coating the resultant soln. by a spin coating method, spray method, etc. on a substrate on which an optical waveguide is formed. The substrate is then prebaked by an electric furnace, IR heating, etc. in a dry atmosphere, by which the org. solvent in the film is removed and the adhesiveness to the substrate is improved. The pattern is then backed by the irradiation of far UV rays or X-rays through a mask or the direct irradiation of electron rays and ion beam thereon. The backed pattern is developed with a suitable developing soln. and is washed and thereafter the pattern is post-baked to have the higher adhesiveness and to remove the solvent picked up during the development. The element is thus made less susceptible to the injury by light and the mechanical strength thereof is much improved as compared with a low-molecular org. compd.
