 | An animal-shaped toy was provided as a therapeutic tool to patients with severe dementia during a therapeutic program and after dinner. The occupational therapist delivered three animal shaped toys a gorilla, a tiger and a dog during the therapeutic program. These toys performed amusing actions. The occupational therapist observed the activities of the patients and classified them into six categories (no reaction, close observation, talking, clapping, patting the toy, taking ... |

|
| Effect of humidity in atmosphere gas, air, or argon, is investigated for the tribochemical reaction in Si3N4-23% TiN-Si3N4-23% TiN sliding contact system using pin-on-plate testing by reciprocal movement of the pin against a plate. In comparison with the above system, an examination is also conducted on Si3N4-Si3N4 couple. The experimental results have shown that the wear rate decreases with increasing humidity and the wear property is somewhat improved by adding ... |

|
| A traction type inspection pig system for external corrosion in buried gas distribution pipeline has been developed. This specially designed inspection pig can pass through 1.5 DR elbows and sleeve joints, and has a high magnetizing efficiency. The existence of corrosion defects is determined from inspection signal map and the pipe inside image obtained by TV camera. Field tests show that this system is highly durable and can detect corrosion ... |

|
| The authors reported the results of the temperature dependence of bend strength and aging properties conducted on sintered Y-PSZ materials, prepared by hot isostatic pressing under an oxygen-containing atmosphere (white-HIPed (W-HIP) material), in order to eliminate the degradation in strength due to the oxidation of carbon and improve their mechanical strength at high temperature. PSZ materials containing 2.5, 3.0, 4.0 and 5.0 mol% yttria and 0.1 to 0.5 wt% alumina ... |

|
| Prediction of tool temperature is very important to improve its life, since tool life is strongly influenced by increase in temperature of tool surface in piercing and rolling process of seamless steel pipes. The temperature of plugs under some piercing conditions of cross roll and press roll piercers was calculated. Actual temperature of plugs were measured and compared with the calculated results to confirm the validity of calculation. In addition, ... |

|
| The wear rate of high C-Cr steel (AISI 52100) has been measured when lubricated with gasoline, ethanol, and water. The wear experiments were performed in air and argon in order to study the relationship between the wear and load, the water-ethanol content in gasohol, and the atmosphere. A large wear rate was found in gasohol, having a constant ethanol content which was completely dissolved. Among gasohols of different ethanol content ... |

|
| A summary of several research projects in the nonlinear fault diagnosis is given. Several alternative algorithms for the solution of the nonlinear fault diagnosis problem are presented, together with a diagnosibility theory, and a set of criteria which an 'ideal' fault diagnosis problem should strive to meet.

|
| The purpose of this study is to elucidate the contribution of residual strain and the distribution of alloying elements to SCC in stainless steel. X-ray and electron microscopic observations were carried out with stainless steel immersed in a boiling aqueous magnesium chloride solution (143 C), and it was found that the strain in the surface layer first decreased, resulting in the nucleation of the corrosion pits, and then increased gradually ... |
