We developed a new whole body motion support type mobile suit. This suit can be used separately for supporting the upper and/or lower limbs, for assisting ADL (Activities of Daily Living). We also developed a mobile lifter system which can bear both the equipped person and the suit. This suit and the lifter can be used by motor palsy patients suffering from stroke, spinal-cord-injury, and central nerve disorders. Using this device, these patients can recover normal gait with no risk of falling. In this paper, the brain activity during walking using the suit and normal gait without the suit are compared. According to multiple trials with the suit, the activity of the premotor area decreased. In addition, by walking while swinging bilateral arms (even though these arms were assisted by the suit), the activity in the supplementary motor area increased (this area of the brain is related with memory of motion). Finally, the brain activity during walking on the treadmill and in the sightly long corridor are compared. From the result of this experiment, it is effective for gait training to walk with locomotion, because of the improvement the motivation for training. We can conclude that this suit is suitable to assist patients in walking. Therefore it is important for patients to swing their arms during gait training in rehabilitation.

In order to realize ultra-low flying heights, magnetic spacing variations due to manufacturing tolerances, environmental variations, and write-induced thermal protrusion need to be reduced. To decrease the flying height, we have developed a thermal flying-height control (TFC) slider that carries a micro-thermal actuator. Using the device, the magnetic spacing of these sliders can be controlled in-situ during operation of the drive. First prototype had shown insufficient characteristics when evaluated at a component-level prototype. Therefore, the purpose of this research is to verify drive-level feasibility and better actuator characteristics. After analytical design by simulation of heat transfer and thermal deformation, second type of TFC device was fabricated. Component level evaluation showed sufficient actuator characteristics that met the requirements leading to the development of drives with controllable flying-height sliders. Drive level evaluation showed its effectiveness in reducing the magnetic spacing.

The rapid increase in the recording density of magnetic disk drives has required decreasing the flying height of magnetic head sliders to approximately 10nm. Under such low flying height conditions, however, the heat generated by the high-frequency current in the writer coils and the rise in the ambient temperature both cause local protrusion of head elements. Such protrusion reduces the flying height below the design value, thus reducing the safety margin for head/disk interference. To analyze this problem, the heat transfer in the head slider, the thermal deformation of the head, and the flying height changes of the slider due to the deformation were numerically simulated. The parameter study showed that short pole and shields cause a smaller ambient-temperature-induced protrusion but a larger write-current-induced protrusion, i.e., a trade-off relationship exists.

Today's head/disk interface design has a wide flying height distribution due to manufacturing tolerances, environmental variations, and write-induced thermal protrusion. To reduce the magnetic spacing loss due to these effects, we have developed an active head slider with nano-thermal actuator. The magnetic spacing of these sliders can be controlled in-situ during operation of the drive. After simulating the heat transfer in the slider and resulting thermal deformation of the air-bearing surface, we fabricated a thermal actuator by thin film processing. The evaluation by a read/write tester showed a linear reduction in magnetic height as electric power was applied to the actuator. The actuator's stroke was 2.5nm per 50mW with time constant of 1 msec. We found no significant impact to the reliability of the read element.
