【緒言】鍼刺激では動的経穴にイオン化傾向の異なる銅鍼と亜鉛鍼を刺鍼した時のみ、 表皮表面局所における酸化還元電位 (ORP:Oxidation-Reduction Potential) が有意に低下することを明らかにしてきた。 本実験では、 直接灸および灸頭鍼刺激前後におけるORPおよび水素イオン濃度 (pH) に及ぼす影響について検討した。 【方法】ボランティアの非経穴および独歩可能な患者の動的経穴に直接灸・灸頭鍼 (輻射熱遮断あり・なし) および燔鍼を行い、 刺激前後の測定を行った。 【結果】ORPは非経穴への全ての灸刺激で変化を示さなかったが、 動的経穴では有意(p<0.01)に低下を示した。 一方、 pHでは非経穴または動的経穴に関係なく、 直接灸では有意(p<0.01)に低下し、 灸頭鍼輻射熱遮断では逆に有意(p<0.01)に上昇する変化が認められた。 【結論】鍼灸臨床において、 我々は動的経穴の灸点[+点]には直接灸、 禁灸点[-点]には灸頭鍼を使い分けているが、 本実験により、 直接灸と灸頭鍼刺激では生体に及ぼす作用が逆であることが明らかとなった。

It is well known that the direct drive systems not to use the reduction gears with the clearane and backlash are required for the highly precise position control, whose motor must have high torque at very low speed. The authors have developed a new motor for this purpose and named PM vernier motor.In this paper, it is explained at first what is PM vernier motor, the construction and principle, and then the theory able to calculate the torque and how to control its speed are described. It is also shown that the calculated values of torque were agreed well with the experimental results.

Purpose: In acupuncture and moxibustion medicine, acupuncture and moxibustion do operation at acupoints (static acupoints) and reactive points (dynamic acupoints) in the skin. In the present study, focusing on the skin, we evaluated the influences of acupuncture on the oxidation-reduction potential (ORP) and hydrogen ion concentration (pH) in epidermal local. Methods: The study was carried out in volunteers and patient groups. Acupuncture was performed at non-acupoints, static acupoints and dynamic acupoints. Changes in ORP, pH, and Aging Index (AI) after these parameters were evaluated. Results: No significant change was observed after acupuncture at non-acupoints and static acupoints. ORP significantly decreased, but pH showed no significant changes following acupuncture of Cu and Zn at dynamic acupoints. Conclusion: Acupuncture of Cu and Zn at dynamic acupoints may have changed an electric potential in local epidermis, resulting in a change of ORP and AI.

The application of the direct drive system is increasing in the field of robot and factory automation because of controllability with high accuracy. However, it requires the motor high torque at low speed.<br>Although the vernier motor, presented by C. H. Lee in 1963, could produce the reluctance torque in low speed, it involved many problems to be solved. In this paper, the authors have studied the reluctance torque of vernier motor using the finite element field analysis. As the increase of rotor slot number is effective to produce high torque, in our model there are not only winding slots but also small slots on the stator teeth surfaces and the rotor slots are provided in the periphery of the core more than the total number of stator slots by the pole number. The calculated torques have agreed very well with the experimental results.<br>A prominent feature of the control scheme is to control the armature current phase based on the detected rotor slot position, so there is no problem such as pull-in or pull-out in the vernier motor of C. H. Lee. And then the instantaneous torque is controlled by the amplitude of armature current. The experimental results on both the speed control and the position control were also shown in the paper.
