Title: Data controller
Inventor: HARADA TAKAHIRO
IPC: G09G5/39
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To reduce the effect to be exerted upon visual perception by the data read out from the faulty storage area of a data storage means. SOLUTION: A controller 3 converts video signals R, G, B to be inputted via an A/D converter 2 into multilevel data and performs data writings to a data storage device 4 in data arrangements which are different for every data writing operation and reads out the multilevel data in the same data arrangements as that at the time of the data writings to supply them to an LCD 5. Even when a faulty area is present in the data storage device 4, since data whose data arrangement orders are different are read out at every readout operation from the faulty area, display positions of the fauly data are dispersed and then the display positions of the fauly data are made to be inconspicuos.

Title: Static mixer
Inventor: HIGUCHI YASUO
IPC: B01F5/06
Filed: 1980-02-25
Abstract: PURPOSE:To mix two kinds of liquids uniformly and continuously by forming the layer-forming parts of a static mixer into a concavo-convexed shape and providing the layer-forming parts plurally in series. CONSTITUTION:The layer-forming part 8 has a divided portion 81 in inlet and an annular portion 82 at outlet. The divided portion 81 has a concavo-convexed shape circumferentially and alternately formed. The layer-forming parts 8 are connected in series and a mandrel 9 is inserted into them. When introducing two kinds of liquids to the first stage layer-forming part 8, they enter a concave portion 84 and a convex portion 83 and move toward the outlet, during which period they are gradually spread thinly and the number of layers is increased by twofolds. Thus, while they move to the first stage, the second stage, the third stage, and so on of the layer- forming parts 8, two kinds of liquids come into contact each other throughout the whole length of circumferential direction, and uniform mixing is therefore performed.
