Abstract: A functional composite material characterized by being molded by solidifying by a resin base material a martensite-phase shape memory alloy wire produced by cold drawing a shape memory alloy which changes between an austenite phase and a martensite phase via a phase transformation temperature. The material enables a smooth motion memorized in the shape memory alloy.

Abstract: Disclosed is a shape memory alloy wire subjected to a cold drawing work, which comprises a shape memory alloy in a martensitic phase which assumes an austenitic phase or a martensitic phase through phase transformation temperatures, has a diameter of 60 ?m or less, and has a reverse transformation termination temperature of at least 250° C. By using the alloy wire, a composite material having the alloy wire embedded in a resin having a molding temperature as high as 180° C., such as a glass fiber reinforced resin or a carbon fire reinforced resin, without fixing of both wire ends.

Abstract: An acoustic-emission sensor includes a composite synthetic resin-ceramic piezoelectric element which has a plurality of substantially mutually parallel columnar ceramic piezoelectric bodies. The columnar ceramic piezoelectric bodies are polarized in a longitudinal direction and are disposed in a synthetic-resin matrix. Since only longitudinal waves can be detected from among acoustic-emission waves, an intensity and variation in intensity can be detected accurately.

Abstract: A UCN-1028D derivative represented by the formula: ##STR1## has protein kinase C inhibitory activity and is expected to be used as an active ingredient in anti-tumor agents, etc.

Abstract: An ultra-sonic senor system suitable for monitoring movement of a vehicle, relative to the horizontal employs two or more coordinated ultra-sonic sensors. The sensors may be mounted at opposite ends or on opposite sides of the vehicle, depending on whether pitch or roll respectively is to be monitored. Each sensor broadcasts ultra-sonic waves and receives ultra-sonic waves reflected by the road surface. The transmission time is known; the reception time is measured upon detection of the peak of the reflected waves. The difference between the two above times yields the distance between the vehicle and the road. The difference between the distances measured by two sensor yields the inclination of the vehicle relative to the horizontal plane.
