We investigated theoretically the relation between these two, taking into account the Weber-Fechner's rule, and derived Eq. (3), and further, we obtained Eq. (4) showing that the odor-concentration is proportional to the concentration of an odorant. In order to inquire into the validity of the equations, we applied them to the same data cited in the previous report, with the conclusion that the equations are considered to be well obeyed, in view of the difficulty in acquiring accurate results in a field work. 1981-03-30T15:00:00Z http://hdl.handle.net/11133/606 タイトル: 半無限弾性地盤上の 2 つの基礎の地震応答 : その 3(鉛直+スウエイング+ロッキング)振動 著者: 中村, 満喜男 抄録: In this paper, the dynamic interaction between two foundations on an elastic half space subjected to propagating seismic waves is investigated analyticaly. 1. Vertical and horizontal components are thought for incident wave due to earthquake. 2. Rocking vibration of the two foundations are added to vertical and swaying vibrations. 3. The two foundations have respectively different width and different height. From these three points of view, the interaction problems are treated analyticaly. But the problems are treated as being two dimensional problem. 1981-03-30T15:00:00Z http://hdl.handle.net/11133/601 タイトル: 電磁近接センサのリンギング回路方式 著者: 深谷, 義勝 抄録: In the rapidly development of automatic control systems over all the kind of industrial societies, electro-magnetic proximity sensors have been provided for the very important roles. It will be reported in this article that we want to propose the damping oscillation type, using a ringing circuit, has more merits and better features compared with than the well known high frequency oscillated types. In the system, the damping coefficient varys with according to moving the distance, which will be detected the difference of the positions of two ones, i.e., the detected target and the sensor coil used in it. Just for the above mentioned reasons, that system is quite suitable for a digital signal processing, because the slop coefficient of the envelope of the damping form in the damping oscillation, may be easily converted into the pulse numbers. Furthermore, using the system, we have made them practice those, which are 1) to expand the range of operations, 2) to have the expandable sensitivity and 3) to make the posibility of construction of simplified circuits using a PUT device. After all, we will report the experiments and the consideration of the above described materials in this paper, below. 1981-03-30T15:00:00Z http://hdl.handle.net/11133/602 タイトル: 名古屋地域の深部地盤構造 I : 第 1 回名古屋鍋田爆破実験 著者: 正木, 和明; 飯田, 汲事 抄録: Through the observations of seismic waves generated from the 1st Nagoya-Nabeta explosion, the deeper ground structure of Nagoya area was clarified. The results are summarized as follows. 1) The thickness of the uppermost soft layer with the velocity of Vp=1.4km/sec is about 90m at Nabeta shot point. 2) The thickness of the dominant surface layer with the velocity of Vp=2.2km/sec is 0.6km at Nabeta shot point. 3) The velocity Vp of the intermediate layer is respected to be 3.0km/sec, but not sure. 4) The depth of the base with the velocity of Vp=5.0km/sec is 1.8km at Nabeta shot point, but it reduces in the northern part of the Nobi plain. 5) Another base with the velocity of Vp=5.8km/sec is respected in the depth of 3.4km. 1981-03-30T15:00:00Z
