Title: Mitsuru Tanaka: Radio Telephone Apparatus Innovations
Introduction
Mitsuru Tanaka is an inventor associated with Saitama, Japan, and NEC Corporation. His listed portfolio includes 4 patents, including work on radio telephone apparatus.
Latest Patents
The supplied patent descriptions concern a radio telephone apparatus that controls signal attenuation and amplification. A voltage-controlled variable attenuator uses a feedback loop to adjust a modulated signal according to a comparator’s result. The apparatus’s power amplifier passes the signal without amplification when the control section does not output a control signal, and amplifies it when that signal is present. A detection circuit uses a change-over switch to select the detection voltage according to the control signal’s status.
Career Highlights
Tanaka’s described invention combines feedback-based attenuation, conditional power amplification, and switched voltage detection in a radio telephone apparatus. The supplied information identifies NEC Corporation as his company.
Collaborations
Naoki Hirasawa is listed as Tanaka’s coworker.
Conclusion
Mitsuru Tanaka’s listed patent work focuses on coordinated signal control in radio telephone equipment, bringing together attenuation, amplification, and detection functions.
