In a data conversion device, a plurality of series of data to be converted is input from a buffer memory device to a data processor. The data processor processes a plurality of the series of the data to be converted, simultaneously in parallel, and outputs a plurality of the series of the data to be converted, simultaneously in parallel. A memory controller of the buffer memory device relates a plurality of the series of the data to be converted to respective conversion tables formed therein by the data processor so as to read converted data corresponding to the series of the data to be converted from the respective conversion tables simultaneously in parallel.

A symmetric-key cryptographic technique capable of realizing both high-speed cryptographic processing having a high degree of parallelism, and alteration detection. The invention includes dividing plaintext composed of redundancy data and a message to generate plaintext blocks each having a predetermined length, generating a random number sequence based on a secret key, generating a random number block corresponding to one of the plaintext blocks from the random number sequence, outputting a feedback value obtained as a result of operation on the one plaintext blocks and the random number block, the feedback value being fed back for using in the operation on another plaintext blocks, and performing an encryption operation using the one plaintext blocks, random number block, and feedback value.

The present invention provides an absorbent article, such as a sanitary napkin or catamenial napkin, wherein the absorbent article has a longitudinal direction and a lateral direction, the absorbent article has: a) a liquid-permeable top layer, wherein the top layer has an extensibility in lateral direction of at least 30% to 70% at 4N / 50 mm, b) a liquid-impermeable backing layer laminated to the top layer, wherein the backing layer has a higher extensibility in lateral direction than in longitudinal direction and the extensibility in lateral direction is at least between 5% and 40% at 4N / 50 mm, and c) an absorbent core positioned between the top layer and the backing layer, wherein the absorbent core has a plurality of non-linear slits and / or linear slits at an acute angle relative to the longitudinal direction through the absorbent core. The absorbent core may be a variety of materials, however one particular example is an absorbent core with a layer of material having a basis weight of between 20 g / m2 to 1000 g / m2 and is an airlaid fiber layers, coform fiber layers, meltblown fiber layers or laminates thereof and laminates of airlaid fiber layers, coform fiber layers or meltblown fiber layers or laminates thereof with a nonwoven support. The absorbent core generally will have a ratio of tensile strength in longitudinal direction and resistance to tear in lateral direction has a value in the range from 3.5:1 to 6:1. The invention further provides a punching die for forming slits in an nonwoven absorbent core material and a process for forming an absorbent article using said punching die.

An expression converting method wherein for each sentence in a corpus, key words are selected from the sentence, a combination of key words that are in a co-occurrence relation is identified from among a predetermined number of combinations of key words among the selected key words, and the identified key word combination and an expression into which the sentence from which the key words are selected is converted are previously associated, and wherein predetermined key words are selected from an input sentence, the selected key words are combined, the key word combinations and the previously identified key word combination of each sentence are compared, one or more than one sentences that coincide or have a high degree of similarity as a result of the comparison are selected, and expressions into which the selected sentences are converted are output.

There is provided an improved laser shock hardening method and apparatus which can eliminate spattering of a liquid and waving of the liquid surface upon laser irradiation, and can stably irradiate a workpiece with a laser beam. Thus, the present invention provides in a laser shock hardening method for carrying out surface processing of a workpiece in contact with a liquid by irradiating through the liquid the surface of the workpiece with a pulsed laser beam intermittently emitted from a laser irradiation device, the improvement comprising: providing a solid transparent to the wavelength of the laser, serving as an entrance window to the surface of the liquid; allowing the liquid to be present in the light path of the laser beam between the solid and the surface of the workpiece; and allowing the laser beam to enter through the solid and irradiating through the liquid the surface of the workpiece with the laser beam, thereby shock-hardening the surface of the workpiece.
