Title: Attraction type eddy current rail brake
Inventor: MARUOKA AKIRA
IPC: B60L7/28
Filed: 1990-11-30
Abstract: PURPOSE:To obviate the necessity of severe control of the gap between a brake and a rail by employing both the frictional force between the pole of an electromagnetic coil and the rail and the magnetic repelling force, produced in the rail by an eddy current when a vehicle passes through the electromagnetic coil, as brake force. CONSTITUTION:When a vehicle is applied with emergency brake, conventional brake functions. At the same time, an electromagnetic coil 1 drops on a rail 4 and a DC current flows through the electromagnetic coil 1 which thereby produces magnetic force. Consequently, the electromagnetic coil 1 and the rail 4 are attracted by the magnetic force to produce a frictional force between the rail 4 and the electromagnetic coil 1 trying to advance in the advancing direction of the vehicle and the friction force functions as a brake force.

Title: Aggregate sieve analysis test and device therefor
Inventor: KAI TATSUO
IPC: B07B1/28
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To shorten a required test time by immersing in water a sieving screen containing an aggregate in a water tank, then draining water off with the simultaneous supply of water from the water tank to maintain water covering the aggregate at a constant level, and performing a sieve analysis of the aggregate in water by shaking the sieving screen with the help of a shaking machine. SOLUTION: A sieving screen 29 containing a sample 30 is fitted into a ring 17 on a shaking table, and the shaking table is shuttled back and forth by driving a motor. Consequently, the sieving screen 29 is shaken under specified conditions. Then a shower water is sprayed over the sieving screen 29 from a shower nozzle 27 with the simultaneous shaking action of the sieving screen 29. These procedures result in the automatic drainage of water from the water tank 4 through a drain port 13, if the water level WL is flush with the height of the drain port 13. Therefore, the internal water level ML of the water tank 4 is maintained at the height of the drain port 11, if the shower water continues to be drained. The sample 30 contained in the sieving screen 29 is automatically subjected to a shaking action under specified conditions, while receiving the shower water.  Thus the sample 30 undergoes a sieve analysis test by the sieving screen 29 in such a manner that the sample is filtered while being water-washed.
