Title: Innovations of Yoshiyuki Takizawa
Introduction
Yoshiyuki Takizawa is a notable inventor based in Tokorozawa, Japan. He has made significant contributions to the field of electronics, particularly in the development of devices that enhance audio and signal processing. With a total of 6 patents to his name, Takizawa's work reflects a commitment to innovation and technological advancement.
Latest Patents
One of his latest patents is a pickup level control device for a system for reading out recorded information. This device features a pickup element that produces a pickup output signal. It detects a DC component of the pickup output signal and generates a level control signal. The voltage level of the pickup output signal is then controlled in response to this level control signal. The control is achieved through a variable impedance element connected to the pickup element, ensuring that the peak level of the AC component remains below a predetermined level.
Another significant patent is an amplifier circuit that includes an operational amplifier and a negative feedback circuit. In this design, an input signal is applied to the non-inverting input terminal of the operational amplifier, resulting in a first output signal from the output terminal. This first output signal is fed back to the inverting input terminal through the negative feedback circuit. The negative feedback signal is further processed through an impedance converter, yielding a second output signal with a low distortion factor.
