  • Patent number: 5568092
    Abstract: A differential amplifier includes an input stage for receiving input signals, an output stage for generating output signals, and an attenuating circuit for attenuating the output signals and feeding attenuation signals back to the input stage. The input stage includes a current switch formed by two transistors connected commonly to a current source and each connected to two load amplifiers. The load amplifiers are controlled by the attenuation signal, to substantially reduce the amplification of the two transistors.

  • Patent number: 5468210
    Abstract: Disclosed is a process of thermal treatment in a tissue comprising embedding an implant element in an organism and externally applying a high frequency magnetic field characterized in that the implant element comprises a magnetic exothermic member partially or completely covered with a non-magnetic insulating film.According to the present invention, the temperature range required in the process of medical treatment in tissue (42.degree. C. to 43.degree. C.) can be more effectively maintained compared with a conventional magnetic exothermic member. Because of the complete coverage with an insulating film, a magnetic exothermic member having a higher Curie temperature than that of the conventional magnetic exothermic member can also be employed. The magnetic exothermic member can provide an isotropic exothermic characteristic when the powders are molded and the components of the magnetic exothermic member never dissolve in a living body.
