Title: Image reproduction method by ultrasonic wave or electromagnetic wave holography
Inventor: SUMIYA HIROAKI
IPC: G01N29/06
Filed: 1985-12-27
Abstract: PURPOSE:To speed up image reproduction processing by completing the reproduction of an area which is made into an image the moment all the prescribed scans regarding an object end. CONSTITUTION:When an image is reprduced by ultrasonic holograph based on a synthetic aperture method, a hologram H16A is given as complex holograms Hr and Hi, and a space wave propagation function G17A used for reproducing an image as complexes Gr and Gi. A reproduced image F18A can be obtained according to an equation F=H.G=(Hr.Gr-Hi.Gi)+j(Hr.Gi+ Hi.Gr). Transmitters and receivers are sequentially scanned to reproduce an image according to the equation. The reproduced result is allocated on the reproduced image F18A, coherence- added to the value of a reproduced image F reproduced before said scan is excecuted, and stored. Thus the image reproduction processing and the scan operation of the transmitters and receivers can be co-currently made, and the image of the area which is made into an image can be completed the moment all the prescribed scans end.

Title: Magnetic recording medium
Inventor: KISHIMOTO MIKIO
IPC: H01F1/11
Filed: 1985-12-26
Abstract: PURPOSE:To decrease electrostatic noise and to permit good high-density recording by incorporating hexagonal ferrite powder contg. Fe<2+> ions in the powder particles into a magnetic layer. CONSTITUTION:The magnetic powder is preferably the planar hexagonal ferrite powder which contains the Fe<2+> ions in the powder particles and of which the axis of easy magnetization is in the direction perpendicular to the plane of the particle plate. The effect of improving electrical conductivity is hardly admitted if the content of Fe<2+> is lower than 0.01 in terms of Fe<2+>/Fe<3+> ratio and the magnetic characteristics are debased when the content is increased to 0.2 or above. The content of the Fe<2+> is, therefore, kept within a 0.02-0.10 range in terms of Fe<2+>/Fe<3+> ratio. The incorporation of the Fe<2+> ions into such hexagonal ferrite powder is usually executed by mixing an aq. metallic soln. of barium or the like and aq. caustic soda soln., bringing the co-deposit of the resulted hydroxide of the metallic salt into reaction with heating in an autoclave, heating the resulted planar crystal in air and reducing the hexagonal ferrite powder formed in such a manner.

Title: Detection system for end of data transfer
Inventor: IKEDA MASAYUKI
IPC: G06F15/163
Filed: 1990-10-31
Abstract: PURPOSE:To reduce the interruption frequency by producing an interruption when all desired packets are transferred without producing the interruptions for each packet and when a single message is divided into plural packets and transferred. CONSTITUTION:A reading part 20-0 reads out a pointer 11-1 and a deciding part 21 checks whether the value obtained by giving -1 to the contents of the pointer 11-1 through a subtractor part 20-2 is equal to zero or not. If not, the value received -1 is written into the pointer 11-1 by a writing part 20-1. These operations are successively applied to the acknowledge packets transferred from other PEs. When the part 21 detects that the value subtracted by 1 and written into the pointer 11-1 is equal to zero, a transfer/reception control part 12 informs a CPU 10 of an interruption. Thus the CPU 10 recognizes that a pair of messages are all transferred. As a result, the interruptions can be decreased in a communication state and then the overhead can be reduced.
