摘要： PROBLEM TO BE SOLVED: To provide a thin-film tactile sensor for an artificial arm/leg, a robot, a manipulator, an in-body type medical equipment, an artificial skin and the like which is sensitive with less error, with no compensation circuit required. SOLUTION: There are provided a temperature detecting thin-film where a temperature sensitivity is high while a distortion sensitivity (or pressure sensitivity) is low as well as a distortion detecting thin-film where a distortion sensitivity (pressure sensitivity) is high while a temperature sensitivity is low. These two thin-film resistors, different from each other in feature, are arranged parallel or laminated so that both temperature and distortion (or pressure) are provided at the same time without using a compensation circuit.

摘要： PURPOSE:To produce an Al-base alloy having low thermal expansion characteristic, high strength, and high toughness by preparing an alloy consisting of specific percentages of Al, Fe, rare earth elements, Si, etc., and containing specific volume percentages of amorphous substance. CONSTITUTION:An alloy, having a composition represented by Al100-a-b-cMaXbSic(where M means one or more elements among Fe, Co, and Ni and X means one or more kinds among Y and rare earth elements), is prepared. In this formula, a=5 to 15%, by atom, b=0.5 to 15%, and c=1.5 to 7.5%. A quartz tube 2 is charged with the alloy. After melting by means of high-frequency heating coil 5, the resulting molten metal 4 is pressurized by means of argon gas, sprayed through a nozzle hole 3, and brought into contact with a cooling roll 1 made of copper to undergo rapid cooling, by which a foil 6 containing amorphous substance by at least 50% by volume percentage is produced. By this method, the foil 6 composed of the Al-base alloy having low thermal expansion characteristic, high strengthm and high toughness can be obtained.

摘要： PROBLEM TO BE SOLVED: To provide a skin state feedback type bedsore preventive and therapeutic system which is capable of drastically reducing the burden of a nursing person, is simpler and more inexpensive and is extremely high in a preventive and therapeutic effect. SOLUTION: The skin state feedback type bedsore preventive and therapeutic system is provided with a pressure sensitive sensor 23 which detects the contact pressure of the skin of an area where the bedsore is liable to occur, a temperature sensitive sensor 22 which detects the body surface temperature of the skin 30 in the area where the bedsore is liable to occur, a surface electrode 21 which is pressed to the skin right above the nerves and muscles around the area where the bedsore is liable to occur and a microcomputer-controlled electric stimulation device 1 which captures the pressure information and temperature information from the pressure sensitive sensor 23 and the temperature sensitive sensor 22. The system described above outputs the stimulus waves to the surface electrode 21 in accordance with the set values of the pressure and temperature to induce the bedsore which are previously set in the electric stimulation device 1 and carries out the decompression and circulation impression with the muscle twitch by electric stimuli so as not to give rise to the increase of the skin pressure and the fall of the skin temperature to induce the bedsore.
