发明名称 ROTARY TRANSFORMER FOR MAGNETIC RECORDER/REPRODUCER
摘要 <p>PURPOSE:To omit labor for attaching electronic components, such as a coil and a signal amplifier and to scarcely receive a signal disturbance from other circuit, etc., by laminating ceramics to form a ceramic laminate for forming the component, such as the coil and the amplifier. CONSTITUTION:A rotary transformer 18 is formed of a ceramic laminate for composing electronic components T, C, such as coils 21, 22 and a signal amplifier by laminating ceramics. For example, a rotary transformer rotor 19 of a rotary head drum mechanism 11 of a magnetic recorder/reproducer of VTR, etc., is formed of a ceramic laminate formed by laminarly superposing ceramic thin plates, and a rotor coil 21 is integrally formed by laminarly superposing the plates. Further, a rotary transformer stator 20 is formed of a ceramic laminate formed by laminarly superposing the plates, the plates are laminarly superposed to integrally form electronic components T, C of parts of capacitors of various electronic components for forming the stator coil 22 and the amplifier 23.</p>
