Title: Hirohito Goto: Innovator in Ferrite Single Crystal Production
Introduction
Hirohito Goto is a notable inventor based in Gyoda, Japan. He has made significant contributions to the field of materials science, particularly in the production of ferrite single crystals. With a total of 2 patents, Goto's work has advanced the understanding and application of ferrite materials in various industries.
Latest Patents
Hirohito Goto's latest patents include a process for producing ferrite single crystals and a process for producing ferrite single crystals for high frequency applications. The first patent describes a new method for the preparation of Mn-Zn or Ni-Zn type ferrite single crystals. In this process, ferrite materials are provided in the lower portion of a crucible and completely dissolved. The crucible is then moved within a predetermined atmosphere of temperature gradient. A solid that is in equilibrium composition with the ferrite materials is supplied into the crucible while the dissolved ferrite materials crystallize from the lower extremity, maintaining a constant liquid-phase zone depth. This innovative method allows for the growth of ferrite single crystals that are at least about 800 mm in length and homogeneous in composition throughout their length.
The second patent focuses on producing Ni-Mn-Zn ferrite single crystals for high frequency applications. In this process, a sample comprising specific molar percentages of NiO, MnO, ZnO, and Fe₂O₃ is melted and subjected to crystal growth under an oxygen partial pressure of below about 100 Kg/cm². This advancement is crucial for enhancing the performance of ferrite materials in high-frequency applications.
