●—後藤さんが社長に就任されてから、この1年半で花王の情報戦略にも大きな変化が見られるようになりました。最近では、基幹システムを日本アイ・ビー・エムにアウトソーシングする決断を下しましたが、どのような経緯だったのですか。後藤—時代が変われば、仕事のやり方を変えていくのは当然のことです。

Power transmission systems using gears require both large capacity and miniaturization. As a result, the gears used in power transmission need to be strong enough to withstand high loads and high engine speeds. Because surface damage and temperature are related, it is very important to know the surface temperature of gears in operation. However, measuring the surface temperature of gears in operation is difficult. As an effective means to measure the surface temperature, method of using dissimilar metals is known. The voltage proportional to surface temperature was produced by contacting dissimilar metals. This is known as Seebeck effect. The authors tried to use two simple ferrous metals. In this study, S55C (Carbon steel) and SUS316 (Stainless steel) were selected to dissimilar metals. Both dissimilar metals were heat-treated and surfaces were hardened. SUS316 was performed plasma carburizing process and S55C was performed induction hardening. As for the gear, it is known that the two or more teeth will mesh simultaneously. In order to remove the influence of the number of tooth in operation, the gear of two sheets were made into the one structure meshed by turns (combined lacked gear). When making the gear of two sheets into one structure meshed by turns. The experiments were operated on maximum condition of contact pressure 1.47GPa in a pitch point. As a result, surface temperature measured almost successfully by combined lacked gear by SUS316 plasma carburizing process and S55C induction hardening. When we compared the experimental values and the theoretical values using Blok's formula, surface temperatures on gear teeth values were largely same.

問 2001年3月期決算は経常利益で20期連続増益を達成しましたが、今期はついに連続増益記録が途絶えるそうですね。成長が止まったと見て、株価は低迷していますが。 答 発展途上国ならともかく、先進国の中で10%以上の成長を求める方が異常ではないかと思います。花王にとっては非常に辛い状況ですよ。
