Abstract: A hydrophobic film is formed on the electrode foil surface by adding a straight-chain saturated dicarboxylic acid represented by the general formula: HOOC(CH2)nCOOH (wherein n indicates an integer from 9 to 11) to the electrolytic solution for medium/high-voltage electrolytic capacitor. Addition of a large amount of water to the electrolytic solution is allowed since this hydrophobic film suppresses the hydration reaction between the electrode foil and water. Further, it is possible to retain good lifespan property of the electrolytic capacitor in a medium/high-voltage electrolytic solution by having low specific resistance property and by suppressing the hydration decomposition of the electrode foil, wherein the electrolytic solution is azelaic acid, sebacic acid, 1-methyl-azelaic acid, 1,6-decanedicarboxylic acid, or a salt thereof dissolved in a solvent having ethylene glycol as the main component.

Abstract: A current density changing portion is formed in a heating process on an upper base side with respect to a center portion of a flat metal plate in a direction of current flow, by passing current from a lower base side to the upper base side of the flat metal plate which is rectangular when viewed from above. As a result, a quenchable portion is formed on the upper base side with respect to the center portion of the flat metal plate in the direction of current flow, and a non-quenchable portion is formed on the lower base side with respect to the center portion of the flat metal plate in the direction of current flow. The flat metal plate is press-formed after the heating process, so a complex die cooling structure is not necessary during press-forming, which enables the die cost to be reduced.

Ultrasound waves are emitted from the piezoelectric material by applying a voltage between the signal electrode and the ground electrode. A switching element switches a connection between the signal electrode and the ground electrode from a closed state to an open state, and vice versa, in accordance with a control signal for controlling whether or not to emit the ultrasound waves. The switching element changes from the closed state to the open state in accordance with the control signal for emitting the ultrasound waves, and changes from the open state to the closed state in accordance with the control signal for suspending emission of the ultrasound waves. The ultrasound probe can maintain the reliability of the piezoelectric material when the temperature is high or changes suddenly.
