 note = {1. Head Pressure As one way of getting the basic materials in order to constitute desirable pillows, the writer put into practice the measurement...... preliminary and main ones・・・・・・of head pressure and the deformation (the hollows) it makes upon pillows, with a total number, 560, of persons including both adults and children. While the measurement of head pressure is to be dealt with here, that of the diformation will be done in another paper. The method of the measurement is to fix a transparent vinyl pipe to an end of a water pillow, and then to pour water into it and give pressure, so as to raise the water in it. The procedure at that time is: (1) to measure the height of the water inside the pipe, (2) to measure load corresponding to that hight and regard it as head pressure, and then, (3) to demonstrate the relationship between the position of the human body and head pressure, and set up a coefficient of head pressure, (4) to refer to the method to calculate approximate quantity of head pressure with each person., Article, 信州大学教養部紀要. 第二部, 自然科学 4: 73-87(1970)},
