Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To use used paper without in particular considering the surface to be set of paper by operating a double side unit when it is detected that the character, image or contamination on a recording medium is a predetermined level or more to reverse the recording medium to the opposite side of a detected surface. SOLUTION: An operation panel 12 has an operation switch and an LED display device and an image reader 13 has function converting the analogue signal from the image sensor present in the vicinity of a paper supply port to a digital signal by a predetermined converter circuit to discriminate the presence of an image from this read data. That is, the image reader 13 has function applying light to set paper to read an image or the image of a character and discriminating whether paper is white or contaminated or whether a contamination degree can be permitted. A double side unit 14 reverses paper once passing through a fixing unit and again performs developing operation to the rear surface of paper.

Filed: 1985-10-23
Abstract: PURPOSE:To improve the accuracy of a core forming size by providing desired recesses to a substrate by making use of the crystallographic anisotropic etching characteristic of a substrate material, forming a magnetic film thereon and flatting the surface until the substrate material appears and the magnetic film of the recesses is separated. CONSTITUTION:An SiO2 film 42 by a thermal oxidation method is formed on the Si substrate 41 and is patterned to the size of a lower core shape by using an ion etching method with a resist as a mask material. The substrate is immersed in a KOH soln., by which the recesses are obtd. A thin magnetic film 43 is formed by sputtering and the surface thereof is flattened until the film 43 is separated in the recesses by which the lower core is obtd. The good head having no variance in the film thickness and size of the lower core on the same substrate is thus obtd.

Title: Absolute value accumulator
Inventor: KATSUYAMA TAKASHI
IPC: G06F7/50
Filed: 1993-08-27
Abstract: PURPOSE:To sufficiently shorten the time required for accumulation as the whole regardless of a large. number of negative values at the time of executing the accumulation of absolute values. CONSTITUTION:When inputted data 1 is a positive value, the accumulation processing is performed once in an adder 14 in the same manner as usual. When inputted data us a negative value, the value obtained by inverting all of bits, the accumulated value, and the carry are subjected to the addition processing once by the adder 14 having the normal constitution. The absolue value of the negative value is obtained by inversion of all of bits and addition of carry '1'. Consequently, the accumulation processing speed is fixed independently of the sign of the inputted value, and the operation is performed at a high speed.
