Hydrographic Office also devised a wave recorder of pressure type under 
Y. Tsukamoto's direction. Yoshida and Kajiura used this instrument for the 
observations of surfs along the Japan Sea Coast. 
In 199, Hishida(81) considered the shape of sounding wire in the water 
from the observations by the non-protected reversing thermometers.
