Japan: Magnitude 7.5 Earthquake Hits Tohoku, Tsunami Warning Issued 7

A magnitude 7.5 earthquake struck off the Sanriku Coast in the Tohoku region Monday afternoon, April 20, triggering a tsunami warning of up to three meters for Hokkaido, Aomori, and Iwate. The footage captures the moment an earthquake alert sounds, as rails hum and vibrate and overhead wires sway in the tremor in Hakodate, Hokkaido.

Piezo Sonic (Setagaya-ku, Tokyo) has released a high-torque ultrasonic motor, the PSM60N. The ultrasonic motor rotates by minute vibrations and frictional force. Since it does not use coils and magnets, it can be used in high magnetic field environments such as magnetic resonance tomography (MRI) systems.The company's ultrasonic motor uses a piezoelectric element to vibrate a ring with a comb-shaped slit. When the rotor (rotating body) is brought into contact with the ring, the vibration of the teeth is transmitted to the rotor, which rotates. The comb tooth structure amplifies the vibration. We chose a material with high friction to increase the torque. The maximum torque is 1.2 Newton meters, which is 5 to 10 times higher than a DC motor of the same size. The motor is also equipped with an optical encoder. (Photo taken on December 4, 2019, credit: Nikkan Kogyo Shimbun / Kyodo News Images)

4D movie theater opens in Kanazawa

4D movie theater opens in Kanazawa

Seats vibrate at Kanazawa Korona Cinema World, a movie theater complex in Kanazawa, central Japan, on Dec. 16, 2015, after it introduced 4D features -- sensor-equipped motion seats, wind, smoke, sprayed water, scents and other special effects -- in a theater. The theater is the first in the Hokuriku region to have such features. (Kyodo) ==Kyodo
