Title: Liquefaction preventive foundation structure for ground
Inventor: ASAYAMA KINGO
IPC: E02D27/34
Filed: 1983-12-30
Abstract: PURPOSE:To construct a safe and strong foundation ground even against earthquake by a method in which drain piles filled with a draining material are driven around a custom-made pile as a core, and drain columns are driven without being overlapped in the same ground. CONSTITUTION:When a knotted pile 1 is driven by a hammer, etc., the pile 1 is driven while packing a draining material 2 into the aperture formed around the pile by the insertion of the knot 4. Drain columns 5 are driven in the portions where there is a shortage of draining effect by the drain piles in the lower ground of the structure, such as around the piles. The drain columns 5 are driven in given positions without lapping with the drain piles 3. The liquefaction of the surrounding ground of the foundation piles can thus be completely prevented and much safer foundation structure can be obtained.

Title: Method and apparatus for coding video signal through accumulative error processing
Inventor: RI TOKIKAZU
IPC: H04N19/82
Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To generate a large number of smoothed areas and to keep a large number of edge information sets simultaneously by filtering to eliminate an accumulated error while reserving an edge with a motion compensation video image with respect to a preceding decoded frame. SOLUTION: A random high frequency signal or the like having been left when a motion compensation video image is generated from a frame memory 60 and a motion compensation device is mostly eliminated form the motion compensation video image of a preceding frame decoded and filtered by a filter 61. Then a subtractor 53 produces a difference video image between an original video image of a current frame and the motion compensation video image of a preceding frame decoded and generated by the filter 61. A discrete cosine transformation device 54 transforms the image to a DCT region, since most values are distributed for a low frequency band, the method is effective for zigzag scanning used for a variable length coder 56. Thus, a multiplexer 62 switches a motion compensation video image or a filtered motion compensation image to eliminate an accumulated error.

Abstract: PURPOSE:To prevent the local recess of the peripheral surface of a drum and to prolong the life of the drum by changing a recording start position on a medium on every recording or in every proper recording cycle. CONSTITUTION:A magnetic head 2 must move in a subscanning direction in synchronism with the rotation of the drum 1, and is controlled to start recording from a position obtained by moving in the subscanning direction by a certain length A by setting the detection signal of a position detecting sensor 129 as reference. Namely, by inputting the number of pulses (a) in a pulse motor 160 for performing subscanning, a subscanning table is moved by the length A. At the time of forming a latent image next, the number of pulses a+DELTAa is inputted in the pulse motor 160 from a CPU 118, so that the subscanning table is moved by A+DELTAA, where recording of a 1st line is started. As a result, the magnetic latent image is formed to be deviated b y DELTAA in an axial direction on the drum 1 in comparison with the previous latent image. By changing the value of DELTAa within a certain range (within the margin of paper), the position of the magnetic latent image is moved in the axial direction.
