摘要： Un système EMAT (1) pour la détection de Discontinuités (2) de surface et internes dans des Structures Conductrices (90) épaisses à haute température, comprenant un Aimant (4) générant un Champ Magnétique Statique (SMF) et une Bobine Électrique HF (6) pour induire, ou être induite par, des Courants de Foucault Du Matériau (14). Il comprend un Noyau Magnétique Laminé Matriciel Perforé (22), disposé entre la Bobine Électrique HF (6) et le Matériau Inspecté (3), constitué d'une multitude de Plaquettes Actives HF (29) évidées incorporant un matériau ferromagnétique, et de Plaquettes Passives (53) isolantes évidées. Des Trous Via (41,57) sont percés à travers chaque Plaquette (29, 53) et forment une Ouverture Cylindrique Rainurée (39). Des Boucles De Courant Induit (43) parallèles tournent autour de chaque Trou Via Magnétique (41) des Plaquettes Actives HF (29). Des Moyens de Refroidissement (58) forcent un Fluide Calorifique (60) à passer à travers l'Ouverture Cylindrique Rainurée (39).

摘要： Ultrasound for use in chemical reactions is generated by an electromagnet formed from an ultrasound transducer (22) central feature is a loop of magnetostrictive material wound with coils oriented to produce an oscillating magnetostrictive force when an oscillating voltage is applied. The oscillations in the transducer loop are transmitted to an ultrasonic horn (16) that is immersed in a reaction medium (12) where the ultrasonic vibrations are transmitted directly to the reaction mixture.

摘要： A vibrator vibrates a solution containing a sample to atomize it into fine particulate substance with its activity held, a high-voltage-applied wire electrifies the solution and/or the atomized fine particulate substance to dry them in floating, and the particulate substance is deposited on an earthed substrate by an electrostatic force to immobilize it with its activity held.

摘要： A method of manufacturing an ultrasonic generator adapted to ultrasonic sterilizers, for minimizing the heat input of a magnetostrictive element, comprises the steps of: forming, on a wave guide, melting layers constructed of joining materials such as Al-Si alloy and Sn-Ag alloy which melt within a temperature range of 575~590°C and 230~250°C, respectively, and have tensile strength of 17~25kg/mm 2 and 10~15kg/mm 2 , respectively; and joining the wave guide with the magnetostrictive element.
