Abstract: A bone conduction hearing-aid system includes an intracorporeal unit that is embedded under a scalp and that includes an intracorporeal vibration generator configured to generate vibration by receiving a magnetic field frequency, and an extracorporeal unit that is disposed extracorporeally, that is configured to generate the magnetic field frequency and to apply the magnetic field frequency to the intracorporeal unit, and that is configured to generate vibration by an extracorporeal vibration generator. The vibration generated by the intracorporeal unit and the vibration generated by the extracorporeal unit vibrate a skull.

Abstract: A bone conduction hearing-aid unit embedded under a scalp. The bone conduction hearing-aid unit includes a vibration generator configured to generate vibration, and an anchor. A magnetic field frequency is applied to the vibration generator from the outside of the scalp to generate vibration. The vibration is transmitted to a skull via the anchor.

Abstract: A bone conduction hearing-aid unit that is entirely embedded under a scalp. The bone conduction hearing-aid unit includes a vibration generating device configured to generate vibration, and an anchor fixed to a skull and configured to transmit the vibration to the skull. The vibration generating device is detachably fixed to the anchor.

Abstract: A middle ear sound transmission characteristics evaluation system includes a probe; a measuring probe that includes an actuator that vibrates the probe and a force sensor that outputs a voltage in accordance with a reaction force exerted to the actuator when a tip of the probe is brought into contact with ossicles; an electrode that is installed on or near a round window and detects a potential value of a cochlear microphonic when vibration is applied to the ossicles by the probe; a database that stores a sensor voltage value output by the force sensor before surgical treatment, the potential value detected by the electrode, and surgical details; and a surgical details proposing unit that proposes selected surgical details on the basis of the magnitude of at least one of the sensor voltage value and the potential value measured before surgery with reference to the database.

Abstract: The present invention provides a bump that can prevent diffusion of a metal used as a base conductive layer of the bump into a surface of an Au layer or an Ag layer. A conductive bump of the present invention is a conductive bump formed on a substrate. The conductive bump comprises, at least in order from the substrate: a base conductive layer; a Pd layer; a Pt layer; and an Au layer or an Ag layer having directly contact with the Pd layer, wherein a diameter of the conductive bump is 20 ?m or less.
