Title: Innovations of Katsumi Kanayama
Introduction
Katsumi Kanayama is a notable inventor based in Hachioji, Japan. He has made significant contributions to the field of audio technology, particularly in the development of tape recorders and transcribers. With a total of 12 patents to his name, Kanayama's work has had a lasting impact on the industry.
Latest Patents
One of his latest inventions is the "Foot switch apparatus for a transcriber." This device is designed to connect to a tape recorder, which features a mode control circuit that designates its operation mode. The foot switch includes an automatic backspacing circuit that is coupled to the mode control circuit. When activated, the foot switch rewinds the recording tape by a predetermined length, thanks to the operation of the automatic backspacing circuit.
Another significant patent is the "Automatic backspace device for a tape recorder." This device is engineered to rewind the tape for a specific period of time. It utilizes a transistor that is activated by an electrical current from a time constant circuit, responding to tape reproduction detected by an operating switch. The transistor charges a capacitor, which then discharges a constant electrical current through a parallel-connected transistor in a current mirror circuit. This process allows another transistor to be turned on by the discharge current of the capacitor, facilitating the rewinding of the magnetic tape.
