Abstract: ABSTRACT OF THE DISCLOSURE           A method of electrolytic treatment on the surface of metal web, such as may be employed to fabricate offset printing plates supports, in which the rate of consumption of graphite electrodes used with the process is remarkably reduced.  A current having asymmetric positive and negative half cycles is applied between graphite electrodes disposed in a main cell.  A portion of the current of the half cycle having the larger average value is applied to an auxiliary anode electrode  provided in an independent auxiliary cell separated from the graphite electrodes.  The auxiliary electrode is made of an insoluble material.  By making the current density for anode reaction on the surfaces of the graphite electrodes smaller than the current density for cathode reaction on the surfaces of the graphite electrodes, the consumption rate of the graphite electrodes is greatly reduced.

Abstract: ABSTRACT     Image processing apparatus for increasing the gray scale resolution of a graphic generated by an ink jet printing system wherein the graphic is made up of pixel areas on a receiving surface and each pixel area is comprised of a fixed number of potential dot positions printed with substantially equal sized dots.  A sequen-tial series of image density signals representative of the gray scale color intensity is generated from an original graphic and converted to a dot level value for each pixel.  A pixel's dot level value is compared to a set of integer and non-integer values and pixels having dot level values falling between the same two successive integer values are selected.  A predetermined dot level value is alternately added to the identified adjacent pixels so that one is increased and the other is decreased by the predetermined dot value.  The resulting values are rounded off to the nearest integer and each pixel is printed with its respective new value.  The resulting gray scale color intensity represented by the two printed pixels is the average of the sums of the two printed pixels' dot level values.

Abstract: ABSTRACT     An electronic component mounting system for locating and mounting electronic components on a printed circuit board, the system being capable of mounting any shape of component without damaging the component.  The system comprises a vacuum fastener for suction of an electronic component, which component is carried on a tape.  A carrier carries the vacuum fastener between a picking up position and a mounting position.  An image sensor is responsive to the image of the component after being sucked and as being held by the vacuum fastener, to provide a location signal responsive to the location of the component.  An image signal processor provides an error signal according to the comparison of the location signal to a standard signal representing a standard location for the component.  An NC numerical control device is connected to the signal processor to provide a correction signal for correcting the relative relation between the printed circuit board and the component.  An XY table controlled in it, XY movement by the NC control device carries the circuit board such that the relative position between the component and the circuit board is adjusted according to outputs of the NC control device.  The component has a magnetic mark at a predetermined location and the vacuum fastener has a magnetic sensor so that the component may be picked up by the vacuum fastener at a predetermined location by coinciding the magnetic sensor with the magnetic mark for preprocessing to locate the electronic component.
