Title: Fatigue tester for shape memory alloy
Inventor: NISHIKAWA MASAHIRO
IPC: G01N3/32
Filed: 1989-05-27
Abstract: PURPOSE:To make it possible to perform a fatigue test under the environment close to an actually operating environment and to inspect many pieces of shape memory alloy at the same time by changing external stress, and imparting temperature change. CONSTITUTION:When a sample S is immersed into cooling water by the rotation of a rotary body 1, the sample S is cooled rapidly and transformed into a martensite phase (M phase). Since the sample in M phase is readily deformed, the sample S is contracted by the compressing force of a pushing spring. The length of the sample S is elongated and shortened by the repetition of heating and cooling. The operation is converted into the angular change of a rotary shaft 16 of a rotary potentiometer 15 through an extending lever 18 and a linking arm 17. Finally, said operation is detected as the change in resistance value of the potentiometer 15. The level of the cooling water 2 is monitored with a level sensor 36. When the level is lowered, a solenoid valve 32 is automatically opened, and water is supplied. Thus the water level is kept constant. Therefore, the sample after the end of the test is not left alone for a long time, and the deterioration of the sample can be prevented.

Abstract: PURPOSE:To improve the communication efficiency by tapping the response signal, which is loop-backed and sent to a first mobile station with a base station by a second mobile station. CONSTITUTION:When a dynamic registering signal A is sent to a base station 100 from a mobile station 200, the base station 100 sends a response signal B including an individual number and a dynamic code to the mobile station 200. The mobile station 200 receives this signal B to display the movement on a display device 209, and the completion of the dynamic registration is confirmed. The base station 100 sends the signal B to a mobile station 300 as a dynamic signal C simultaneously with the sending of the signal B to the mobile station 200. The mobile station 300 receives this signal C by a terminal equipment on a vehicle to automatically display it on a display device, and dynamic registration contents of another mobile station are confirmed. Thus, it is unnecessary to confirm dynamic registration contents of another mobile station by voice communication between the base station 100 and the mobile station 300, and the communication efficiency is improved.
