摘要： A sulfur modified polychloroprene is produced in a process which comprises polymerizing chloroprene or a mixture of chloroprene and a comonomer in a neutral or acidic aqueous emulsion by using a cationic emulsifier in the presence of sulfur and a peroxide initiator, and then performing a peptization of the resulting sulfur modified polychloroprene latex by addition thereto of an alkaline aqueous solution in amounts sufficient to reduce the pH of the latex to alkaline conditions.

摘要： A mark representing information of a multivalued level is recorded in each of cells arranged in a recording medium. Upon reproducing the multivalued level from a reproduction signal of the recording medium, the multivalued level of a present cell is judged by referring to a judged multivalued level of a preceding cell preceding the present cell or an ensuing cell ensuing the present cell, or by referring to the judged multivalued levels of both the preceding cell and the ensuing cell.

摘要： A multi-level information recording-reproducing apparatus can accurately determine multi-level information even if recording density is increased. A multi-level information recording-reproducing apparatus radiates a laser beam to an information recording medium by switching a radiation energy level of the laser beam in a multi-level fashion and records a recorded mark in the information recording medium. The multi-level information recording-reproducing apparatus reproduces a multi-level data sequence recorded as a test pattern in the information recording medium, sets a reproduction signal level of a recorded mark based on an immediately-before cell located immediately before a cell to be reproduced, and corrects the radiation energy level of the laser beam so that the reproduction signal level can have a separate distribution from a distribution of another reproduction signal level.

摘要： In a data processing method of converting (n×m−1)-bit data to multi-level data of m symbols of n bits per symbol, n and m being integers satisfying n≧2 and m≧2, respectively, the m symbols each comprising n-bit data are arranged in m columns in an n×m matrix, with a value of each of the m symbols being set to an even or odd number, by creating the m symbols each including (n−1)-bit data of the (n×m−1)-bit data, arranging the m symbols in the m columns so that the {(n−1)×m}-bit data is arranged in upper-side {(n−1)×m} bits of the n×m matrix, and converting the remaining (m−1)-bit data of the (n×m−1)-bit data to m-bit data so that the m-bit data is arranged in a row in lower-side m bits of the n×m matrix.

摘要： The invention provides an optical information recording medium capable of optionally setting the capacitance of the ROM and keeping the physical continuousness in the ROM track and the RAM track. The medium is the optical information recording medium in the land/groove recording system in which the information is recorded both in the convex groove track called land L and in the concave groove track called groove G, and it includes commonly in a sheet of medium a ROM area constructed with the pre-pit row previously formed on the basic substrate and a RAM area capable of being additionally written by the user. The track pitch of the pre-pit row in the ROM area is equal to that of the groove. The RAM area exists on the plain portion between the just adjacent pre-pit rows in the ROM area and on both portions of the land and the groove.
