摘要： A process for producing pyromellitic acid which comprises oxidizing 2,4,5-trimethylbenzaldehyde and/or its oxidized derivative in the presence of a catalyst containing iron, manganese and bromine, or additionally containing zirconium or cerium continuously or semi-continuously using aqueous acetic acid solvent and 0.05-2% by weight of bromide ion. The catalyst used in the present invention has high activity, and the catalyst solution has low corrosive because the reaction is performed at low bromide concentration by using a solvent of aqueous acetic acid. So pyromellitic acid is produced industrially advantageously in high yield continuously or semi-continuously which has been a major difficulty up to now.

摘要： The S/N ratio is improved for recording data to grooves (2-1,2-2) of an optical disc so that as much information as possible can be recorded at the lowest possible frequency band. An optical disc using wobble patterns to record different information has a first groove (2-1) having a first wobble pattern (22) in which one wobble period has a sharp rising edge and a gradual falling edge; and a second groove (2-2) having a second wobble pattern (24) in which one wobble period has a gradual rising edge and a sharp falling edge. Each of the first and the second wobble pattern is represented by a first fundamental and a second harmonic of a Fourier series. The polarity of the second harmonic, which is an even harmonic, of the second wobble pattern is opposite that of the first wobble pattern. A method for manufacturing this optical disc is also provided.

摘要： An airbag comprises an airbag body, and a wrapping member made tearable for preventing the airbag body from returning to its unfolded state. The airbag body is folded and housed on the peripheral edge of an opening on the inner side of a car body, and is folded up into a rod shape so that it may be inflated when an inflating gas flows thereinto so as to cover the opening. The wrapping member is made flexible and long and is wrapped on the outer periphery of the folded airbag body substantially all along the length of the same, so that it may extend obliquely to the axial direction of the airbag body folded up into the rod-like shape. Moreover, the airbag is restrained in its proper folded state substantially all along its length by a simple wrapping operation.
