Title: Suction type floating head device
Inventor: SUZUKI SHIGEHISA
IPC: G11B21/21
Filed: 1978-04-03
Abstract: PURPOSE: To suppress the generation of moment and enhance the follow-up function of the head part to recording media by so forming the shape of suction faces that the acting force of negative pressure passes approximately the center of gravity of a head slider.  
     CONSTITUTION: Groove form parts 20' between plural floating faces 4 of a head slider 30' are partly formed to flat parts 11 being parallel to the floating faces 4 and suction faces 6' are so formed as a whole as to position on the air effluent end B side of the slider 30'. Hence, suction force F 2 ' generates between the GC' of the suction faces 6', but neither suction force nor floating force are generated between AG of the flat parts 11, thus the center of negative pressure distribution L' becomes near the D' point and this D' point becomes (0.4 to 0.6)AB in the distance l' from the air influent end A. As a result, the floating force F 1 ', pressing force F 3  owing to pressing spring and suction force F 2 ' concentrate at the central point of the slider 30' and therefore unnecessary moment may be eliminated and follow-up function is improved.

IPC: H04N5/262
Filed: 1988-02-24
Abstract: PURPOSE:To generate a picture signal having a streak effect in a real time by adding a picture signal outputted from a multiplication means and a picture signal outputted from a frame delay means by an adder means and giving the result to the frame delay means. CONSTITUTION:The inputted picture signal is multiplied with a constant being '1' or below by a multiplication means 1 and the result is outputted to an adder means 2 as a picture signal of the picture whose brightness is reduced. Then the picture signal multiplied with the multiplication means 1 and the picture signal outputted from a frame delay means 3 are added by the adder means 2 and inputted to the frame delay means 3. Moreover, the frame delay means 3 retards the picture signal inputted from the adder means 3 by one frame and then outputs the result. Thus, the picture signal of the picture superimposed with each frame whose brightness is reduced is outputted sequentially from the frame delay means 3. Thus, the picture processing similar to that at open and exposure of the film camera is applied as to the picture signal and the picture signal having streak effect or the like is generated in real time from the picture signal obtained by picking up by a video camera or the like.
