摘要： PURPOSE:To provide suitable radio wave absorbing performance, light weight, excellent mechanical strength and rigidity by using wood chips as a holding material, and combining compositely a carbon molded form mixed with carbon powder and/or carbon fiber therewith and a metal gauze. CONSTITUTION:Carbon molded form 1 of component composition in which carbon powder and/or carbon fiber is mixed together with binder with wood chips and a metal gauze 2 are compositely mixed. Carbon powder, carbon fiber or both are mixed together with binder with wood chips. The carbon powder includes, for example, finely pulverized graphite, coke, etc., carbon black, etc. When the carbon black is applied, conductive carbon black is effective. Thus, a radio wave absorbing material which contains molding texture having light weight, excellent mechanical strength and rigidity and has suitable radio wave absorbing performance is obtained.

摘要： PURPOSE:To provide suitable radio wave absorbing performance, excellent mechanical strength and rigidity by using highly moldable active charcoal as a holding material, and mixing carbon powder and/or carbon fiber therewith. CONSTITUTION:Component composition in which carbon powder and/or carbon fiber is mixed together with binder with powder particles of active charcoal is molded in a shape such as desired wedge, square conical, plate shape, etc., to form a radio wave absorbing material. It is desired to mix the carbon powder and/or carbon fiber at the radio of 10-20g/l to the particles of the charcoal. Thus, the material which contains molding texture having excellent mechanical strength and rigidity and has suitable radio wave absorbing performance is obtained.

摘要： PURPOSE:To grasp the bending state of an excavated hole with real time by fitting an inclinometer to the leading end of an auger shaft of an auger boring and measuring the bend of the excavated hole every optional depth. CONSTITUTION:An auger 1 and an auger shaft 2 are formed on a boring machine and an inclinometer 3 is fitted to the leading end of the auger 1. The inclinometer 3 is constituted of a differential transformer, a distortion gauge, an electrostatic capacity system, an accelerator system, etc. Excavation is interrupted at a previously fixed depth during the excavation, its bearing is selected by a bearing meter 5, the inclinometer 3 is matched with the selected bearing to measure the inclination, and the inclination data are sent to an indication recorder 6. For instance, the detecting direction of the inclinometer is made to coincide with the east and weat direction to obtain data and measure inclination every optional depth. Since the inclined degree of the leading end of the auger is measured with real time and can be fed back rapidly to the execution, excavation can be performed highly accurately.
