Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To estimate a substantial unit water content. SOLUTION: First, at a water absorption content measuring step, aging change of water absorption content of artificial light-weight aggregate is measured. At a volume measuring step, concrete containing the aggregate is placed, and then aging change of volume of the placed concrete is measured. Thereafter, at a water absorption content acquiring step, the concrete is placed based on the measured result of the volume measuring step. Then, a time until the volume of the concrete is not changed is obtained, and the water absorption content of the aggregate at time point of elapse of the time is obtained based on the measured result of the absorption content measuring step. And, at a unit water content calculating step, an amount of water contained in the aggregate is calculated based on the water absorption content obtained at the absorption content acquiring step.  And, the calculated water content is subtracted from apparent unit water content, thereby calculating substantial unit water rate.

IPC: H05K1/03
Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To increase surface insulation resistance and to prevent the propagation loss of a signal at a high-frequency band from occurring by laminating a layer, made of one type of titanium and chrome and a copper layer successively on the surface of a ceramic board and specifying the surface roughness of the ceramic wiring board where a conductor circuit is formed.

By setting the surface roughness of the ceramic board 1 to less than 1μm at Rmax, surface insulation resistance can be increased and the propagation loss of a signal at a high-frequency band can be prevented. When the surface roughness is 1μm or larger, a propagation loss is generated when a signal at a high-frequency band is propagated, and the layer 2 and the copper layer 3 made of at least one type of metal among titanium and chromium remains on the surface of the ceramic board 1, when performing etching, thus reducing the surface insulation resistance of the ceramic board 1.
