  • Patent number: 6673316
    Abstract: A synthesis experiment automation system is provided with a robot, which transports synthesis reaction containers from a reaction container rack to a dispensing/separation position of a dispensing and separation device, and transports the synthesis reaction containers to a predetermined position in a temperature regulator unit of a reaction device, where a reaction is carried out under previously set experiment conditions; and with a computer, which controls the actions of the robot and the operations of the dispensing and separation device and the reaction device in accordance with a plurality of previously set experiment conditions. Accordingly, the synthesis experiment automation system is capable of simultaneously performing a plurality of different experiments as complex as those usually performed by researchers, and, moreover, has a large number of possible experiment operations, and can easily be improved and/or extended.

  • Patent number: 4544610
    Abstract: A spring useful as various machine parts or elements for various machines and apparatuses, which is made of a fiber-reinforced metallic composite material comprising a matrix metal (e.g. a metal having a melting point of not higher than 1,700.degree. C.) and a reinforcement of an inorganic fiber having high modulus of elasticity and high strength selected from a ceramic fiber and a metallic fiber, particularly an alumina or alumina-silica fiber containing alumina of 100 to 72% by weight, preferably 98 to 75% by weight, and silica of 0 to 28% by weight, preferably 2 to 25% by weight, and having substantially no .alpha.-alumina reflection by X-ray diffraction. The spring of the present invention is light in weight and has far greater heat resistance and mechanical properties in comparison with the conventional metallic or non-metallic springs, and hence is particularly valuable from the standpoint of saving energy and saving resources.

  • Patent number: 4338132
    Abstract: A process for fabricating a fiber-reinforced metal composite is disclosed which comprises laminating a plurality of a sheet-like precomposites comprising bundles of filaments of metal reinforcing fibers, among the filaments of which a matrix metal powder having an average particle size of not more than 1/2 of the diameter of the fiber is spread, and among bundles of which a matrix metal powder having an average particle size of 2 to 10 times the diameter of the fiber is spread, and hot-pressing the resulting laminate either in a vacuum or in an atmosphere of an inert gas.
