摘要： A pseudorandom number generator reduced in size while maintaining high security is disclosed. The generator has a state storage unit of 2 blocks (n bits per block) and a buffer of plurality of blocks, and mixes their contents to obtain a random number sequence. The mixing is done by a nonlinear transformation unit for inputting the stored content of the buffer to output data of the same size as the input data, a first linear transformation unit for inputting the content of the state storage unit and the output of the nonlinear transformation unit to store an output into the state storage unit, and a second linear transformation unit for inputting the stored content of the buffer and the stored content of the state storage unit to store an output into the buffer. The mixed content of the state storage unit is output as a random number sequence.

摘要： An object of the invention is to provide a reflective sheet that uses silver which exhibits a high reflectance as a reflective layer and is excellent in light resistance and wet heat durability, as well as a lamp reflector that uses the sheet and does not generate a luminescent line. The reflective sheet constituted by sequentially arranging at least three layers, that is, an underlying layer, a metal layer made primarily of silver and a protective layer on a polymer film is laminated with a molded body by using an adhesive, allowing a polymer film side of the reflective sheet to be a surface to be adhered, to prepare a reflector. The resultant reflector is processed to prepare a lamp reflector.

摘要： A hash value generation device has a control part (120) that divides an inputted message into N message blocks of a predetermined data length (N being a natural number), repeats transformation processing a predetermined number R of rounds (R being a natural number larger than or equal to 2) for each of the message blocks, and repeats, N times, block cipher processing in which a value calculated in the transformation processing of R rounds for the n-th message block (n being a natural number) is used as key information for the (n+1)-th message block, to generate a hash value of the inputted message. In shift processing performed in the transformation processing of the control part (120), at least one odd number and at least one even number are included among numbers of bits by which a shift is performed.

摘要： The present invention provides a removing method of a tube. Upon removing a tube 3 increased in diameter and fixed to a tube-sheet 1, an inserted portion 3a which is fixed to a tube-hole 2 of the tube-sheet 1 is heated and then cooled, thereby reducing its diameter. The inserted portion 3a is loosened from the tube-hole 2. Then, a region 3h opposed to a groove 4 formed in an inner circumference of the tube-hole is heated to a red-hot state, and the tube 3 is stretched in its axial direction, the red-heated region 3h is stretched to reduce its diameter and cut the region 3h, thereby pulling out the tube 3 from the tube-sheet 1.

摘要： A bus bar for power supply is comprised of a pipe-shaped outer conductor and at least one inner conductor inserted therein. The inner conductor is also formed in a pipe shape and serves as a coolant flow passage. Insulation is interposed between the outer conductor and the inner conductor to electrically isolate them from each other.

摘要： The invention aims to provide a hash function whose safety can be evaluated. To achieve this, a message that is input to a message blocking unit 122 is split into multiple message blocks, and shuffled at a shuffling unit 126 using block ciphers per message block from a round key generated at a first round-key generation unit 124 or a second round-key generation unit 125 using a round constant generated at a round-constant generation unit 123. In calculation of the block cipher, particular split data among multiple split data obtained by splitting the blocks are transformed with an F function, and an exclusive disjunction of the transformed data with other particular data is calculated. Using the F function, a transformation including at least a nonlinear transformation is performed more than once.
