Abstract: A rotary plater and method of plating are provided which improve the uniformity of plating across a plating surface of a workpiece. A plating solution distribution device is located in a plating cup between an anode and a cathode in a spaced relationship therebetween and is centered about a vertical axis of the plating cup. A motor is provided for relatively rotating the cathode and the plating solution distribution device with respect to one another. The plating solution distribution device distributes the plating solution over the plating surface at a distribution rate which increases radially outwardly from the vertical axis. With this arrangement the volume of plating solution at the outer periphery of the plating surface is enriched with ions to promote plating uniformity.

Abstract: A dual gap horizontal thin film inductive head is provided which writes wide and reads narrow so as to avoid noise problems when reading an information track on a magnetic medium. The head has first and second gap layers between first and second horizontal pole tips. The pole tips and the corresponding pole pieces of the head are constructed of a high magnetic moment material, such as NiFe (Permalloy). The first gap layer is constructed of a magnetic insulator, such as tungsten, and the second gap layer is constructed of a low magnetic moment material, such as NiFeCr. Accordingly, the magnetic moment of the second gap layer is lower than the magnetic moment of the first and second pole tips and the corresponding first and second pole pieces. During recording both gap layers function as a gap because the second gap layer is saturated and behaves as a magnetic insulator.

Abstract: A method and apparatus for validating the electronic and coding of an incoming ideographic character, having a particular complexity and encoded according to a group of predetermined basic stroke elements and stroke sequencing rules to define an incoming character code, for use in association with a set of standard ideographic characters, encoded according to the group of pre-determined stroke elements and stroke sequencing rules to define standard character codes, each standard character having a certain complexity, the set being ordered according to the complexities of the standard characters.
