black lead graphiteとは 意味・読み方・使い方

To provide a pencil lead which has sufficient wearability and a large concentration, maintains a practical breaking strength, and has a black color different from the light-reflecting lead color of a line written with a conventional lead containing graphite as an extender.例文帳に追加

磨耗量が十分あり且つ濃度が濃く、そして実用折損強度を維持し、従来の黒鉛を体質材とした光の反射のある芯体の鉛色の筆記線とは異なり、黒色の色味を有する鉛筆芯を提供すること。 - 特許庁

To provide a pencil lead having a practical anti-breaking strength and exhibiting a pure black color different from that of a conventional written mark of a pencil lead having reflection of lights which is made of graphite.例文帳に追加

実用折損強度を維持し、従来の黒鉛を体質材とした光の反射のある芯体の筆記線とは異なり、純黒の色調を有する鉛筆芯を提供すること。 - 特許庁
