Title: Reducing method for ground vibration
Inventor: OHASHI MIKIO
IPC: E02D31/08
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To efficiently form a vibration cutoff space and reduce vibration of the ground by compacting the ground of a boundary territory between a vibration source and the circumferential vibration propagating territory in the outward direction of the circumference, and forming a vibration cutoff space. SOLUTION: A route on the way from a fixed vibration source in which vibration of the ground is generated by construction or traffic to the vibration propagating territory in which vibration is propagated from the vibration source is set as a boundary territory. Vibromotive force of a compacting means such as a shaking machine is set according to the nature of the soil of the ground, strength characteristic, physical characteristic, and the like of the boundary territory. The shaking machine and the like are operated so as to compact the ground of the boundary territory, and a hollow groove-like or shaft-like vibration cutoff space is formed so as to partition the ground at fixed depth. If necessary, compaction reinforcing material made of high polymer additive material such as water absorbing resin, cellulose, or natural resin is used so as to form the vibration cutoff space.  Hereby the vibration cutoff space is efficiently formed, and vibration of the ground can be reduced.

Title: Three-dimensional display device
Inventor: GOTO MASAHIRO
IPC: G06T15/40
Filed: 1989-01-19
Abstract: PURPOSE:To simply display a graphic not hidden in another three-dimensional graphic without increasing the number of hardwares or the volume of operation by allowing a graphic processor to judge a flag at the time of graphic display, and when hidden-surface processing is unnecessary, omitting the hidden-surface processing. CONSTITUTION:In the case of displaying a three-dimensional graphic on a CRT 3, the contents defined in a graphic command stored in a graphic command data memory 6 are interpreted and coordinate conversion is applied to the interpreted contents. Judgement (hidden-surface processing) whether the coordinate-converted result is to be displayed or not is executed from the upper- lower relation of the (z) direction, and only when display is decided, graphic display is executed. Even when the hidden-surface processing is omitted, only the judgement of display/non-display is omitted and bad influence is not exerted upon the display contents (a coordinate position, display colors, etc.). Since the decision of a flag is simple and its storage space is small, an unhidden graphic can be displayed without increasing the operation time or the number of hardwares.
