Winding Pressure of Lap Machine
Journal of the Textile Machinery Society of Japan - Transactions -, 1966 目的 フィニッシャスカッチャの前部にあるラップマシンのラップ巻き取り機構を明らかにし, その機構から生ずるラップ圧縮時のラップに加えられる圧力変化をストレインゲージ, スリップリング, オシログラフなどを使用して測定する.同時にラック上昇距離を測定してラップの平均厚さ, 圧縮角θの範囲などを求め, またラップの圧縮圧力曲線により巻き取り中のラップの挙動の模型的解析を行なう. 成果 1. ラップの平均厚さは0.15cmである。 (16oz/yd) 2. ラップ巻き取り中の圧縮角θの範囲は55～32°であり, これが圧力変化の原因となる. 3. ラップ巻き取り時の圧力は巻き始めでは圧力の変化速度が大きく, 巻き終わりに行くに従って小である.

BAW pressure sensor on LiNbO 3 membrane lapping [PDF]
EFTF-2010 24th European Frequency and Time Forum, 2010 In this paper, we have proposed a new concept for pressure and more generally stress sensors exploiting single-crystal based HBAR. After describing the operation principle, the practical feasibility of the sensor has been shown, yielding electrical results allowing a first characterization of such sensor sensitivity.

Evaluation of Grain Shape Change by Lapping Pressure.
Journal of the Japan Society for Precision Engineering, 1998 Lapping performance is essentially attributed to cutting abilities of grain, which depends on the grain shape. However, it was very difficult to evaluate the grain shape quantitatively, because the grain shape was changing complicatly during lapping. In this study, it was examined how the grain shape characteristics change with lapping pressure.
