Publication number: 20210341426Abstract: A detector that detects an internal state of a plate-shaped object including a fiber-reinforced resin. The detector includes an exciter that applies, to a surface of the object, ultrasonic vibrations of Lamb waves, in a selected frequency range where only a zero-order fundamental wave symmetric mode and a zero-order fundamental wave asymmetric mode of the Lamb waves appear, a vibration detector that detects the applied ultrasonic vibrations propagating in the object, and an internal state estimation calculator that estimates the internal state of the object, by obtaining a propagation time of the ultrasonic vibrations propagating in the object corresponding to each frequency of the Lamb waves, based on the detection result of the vibration detector, estimating the internal state based on a delay time of the propagation time relative to a reference propagation time of the object for each frequency in the selected frequency range, and outputting the estimated internal state.Type: ApplicationFiled: July 15, 2021Publication date: November 4, 2021Inventors: Taku KONDOH, Akihiro CHIBA, Shota TEZUKA, Yoji OKABE, Osamu SAITO, Peiwen DENG

Publication number: 20060120192Abstract: The present invention provides a dummy canister which can cool canisters with good efficiency. Canisters 2A and dummy canisters 2B are attached in a mixed configuration to the storage part 1C of a storage device 1. Each dummy canister 2B is constructed so that this dummy canister can expand and contract in two stages in the attachment direction (which is also the direction in which the cooling air draft flows through). Among these dummy canisters 2B, the dummy canister 2B (1) that is adjacent to a canister 2A is set in a first shape, and has a shorter length. The other dummy canisters 2B (2) through 2B (5) are respectively set in a second shape, so that the length dimension of these dummy canisters is lengthened. As a result, the amount of the cooling air draft that flows around the dummy canister 2B (1) that is adjacent to the canister 2A (3) is relatively large, so that a large cooling air draft can be supplied to the canister 2A (3).Type: ApplicationFiled: January 27, 2005Publication date: June 8, 2006Applicant: Hitachi, Ltd.Inventors: Kenichi Miyamoto, Yoji Okabe
