A phenomenon that passengers are getting sleepy is often found in running cars or trains. If a mechanism can reproduce this phenomenon, it is feasible to put insomnia patients or infants to sleep without any harmful effects. This will bring extreme benefit for insomnia patients or parents of babies. The purpose of this study is to elucidate the sleep-inducing factors of running cars or trains, and the final goal is to develop a machine which reproduces the environment to put people to sleep. For the first step of this study, we investigated the relationship between sleepiness and vibrations on several trains. The sleepability of each train is discussed by the ratio of sleeping passengers. According to the vibration analyses, the results suggest that comfortable vibration for sleep has mainly low-frequency (2 Hz) vibration with particular fluctuation. In addition, it is also guessed that low level jerks contribute the sleepability.

Peristalsis can generally be seen in the digestive organs of animals, and serves various purposes such as transporting or mixing the contents of the digestive tracts. Although this peristaltic movement has been studied by many physiologists, its neural controlling mechanisms have not yet been made clear.This paper describes a biomechanical study on the peristaltic transport mechanism of gastrointestines. First of all, referring to the physiological knowledge established so far, the authors made an assumption about the structure of a neural network which should exist in the intestine itself to control a peristaltic motion (as shown in Fig. 2). Secondly, in order to examine the functional property of receptors, a simulation was carried out on a digital computer, and it was found that the receptors had to hold such a property as are responding to the inside pressure caused by the stuffed contents to be transported. Finally, referring to the above mentioned results a mechanical model for peristalsis was made, and its performances of simulation was examined. It resulted that this model expressed physiological phenomena on the intestinal movement very well, and was able to transport solid stuffs in the various shape.Thus the authors believe that the neural network model proposed by them is valid and represents a principal a neural controlling mechanism to transport contents in the intestine.

In addition, it is also guessed that low level jerks contribute the sleepability.
