Title: Teaching for optically measuring machine
Inventor: TAKEMURA ISAMU
IPC: G01B11/24
Filed: 1986-11-25
Abstract: PURPOSE:To achieve a higher teaching efficiency, by difining a fixed range section on a straight line connecting a relative coordinate value of time at which an edge signal is generated and a relative coordinate value obtained after a fixed time passes from the time as a measuring section. CONSTITUTION:As a relative displacement is generated, an edge signal is outputted at an initial edge point P1. At the same time, values of X-axis and Y-axis counters 34X and 34Y, namely, relative coordinate value P1 is inputted into a CPU 30 while a timer 44 is reset. After a fixed time DELTAT, a coincidence signal (j) is outputted from a setting circuit 46 and hence, a relative coordinate value B1 at the current time is inputted into the CPU 30. Then, the starting point A1 is determined by computation for the symmetrical position between the coordinate value B1 and the relative coordinate value P1 on the extension of segment P1.B1, defining the segments A1.B1 as a measuring section. This eliminates the need for specifying starting and ending points separately thereby achieving a higher teaching efficiency.

Title: Surface layer material containing oil sand and construction method therefor
Inventor: KASHIWATANI TSUTOMU
IPC: E01C15/00
Filed: 1994-10-21
Abstract: PURPOSE: To obtain a surface layer material having improved drainage characteristics and dust preventive property by mixing natural oil sand having a specific particle diameter and natural soil having a specific particle diameter. CONSTITUTION: Natural oil sands of a moisture of 5-18% with a particle diameter of 5mm or less and natural soil of a moisture of 5-18% with a particle diameter of 10mm or less are mixed together to provide a surface layer material, which material is placed on a bedrock soil and uniformly compacted by means of a roller to improve a surface soil. By adjusting the mixture in such a manner, the natural oil sands and natural soil can be mixed easily and dusts are prevented from being generated at the time of mixing at site and the workability can be improved. If the moisture is 18% or more, the sand and soil becomes sticky so that sufficient mixing can not be achieved, and if the moisture is 5% or less, dusts are generated at the time of mixing and field construction and drying cost is needed. In a playground with this surface layer material, damage due to inundation caused by rainfall is very scarce and most of rainwater is repelled by the surface layer and hence the playground can be used even immediately after rainfall.
