13Japan Marine Science Inc.A global maritime solutions consulting company, creating the future alongside clients by integrating profound onsite understanding and advanced technologies. The company provides various services, including consultations on all aspects of maritime affairs, ship construction, and education and training for sailors. The company’s Occilation Test Group employs a large threedimensional vibration table (measuring 6.2 × 2.6 m with maximum loading capacity of 20 tons) to perform commissioned testing, including earthquake resistance tests, transportation vibration tests, and vibration tests of containers holding liquids. The company performs more than 100 tests daily and operates an inquiry desk open to all requests. https://www.jmsinc.jp/products/oscillation/enSM-28 SeismometerThis model is a strongmotion seismometer compatible with the seismic intensity information network proposed by the Fire and Disaster Management Agency of the Ministry of Internal Affairs and Communications. Complying with Notification No. 4 of the Japan Meteorological Agency, it’s an optimal device for constructing earthquake monitoring and disaster prevention systems. Equipped with two seismic sensors, the model is capable of issuing an alarm based on an AND control method. Ethernet is provided as a standard feature for easy integration into network environments. A touch panel provides easy access to various settings and waveform checks. Seismic waveforms are recorded in WIN32 format. Use with the PV24 seismic sensor allows users to implement remarkably reliable lowcost control of external devices. Contact output units can be added to create up to six levels of alarm outputs.The YOKOHAMA LAB of Japan Marine Science Inc. reproduces seismic motions to assess earthquake resistance and the durability of various products. Some of the instruments manufactured by Rion are used at this laboratory. What kind of instru-ments are they?
