Title: Haruki Nishida: Innovator in Frequency Multiplication and Temperature Compensation
Introduction
Haruki Nishida is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of electrical engineering, particularly in the development of innovative technologies that enhance device performance. With a total of three patents to his name, Nishida's work focuses on frequency multiplication and temperature compensation.
Latest Patents
One of Nishida's latest patents is a frequency multiplier. This invention allows an input signal specified by an input frequency to be divided by an out-of-phase type input hybrid coupler into two divided signals. These signals have different phases and are then multiplied by a frequency multiplier, resulting in frequency multiplied signals. The output signal is composed by an out-of-phase type output hybrid coupler, producing a specified output signal based on the multiplied frequency. Additionally, a phase shifter is included to vary the phase difference between the frequency multiplied signals, ensuring they are composed in in-phase.
Another notable patent is a temperature-compensating voltage generator circuit. This circuit compensates for the temperature characteristics of electric devices that vary with ambient temperature changes. It includes a temperature-sensing device that generates an electric signal based on temperature changes and a discriminating device that uses a reference voltage to generate output signals. The circuit also features a distributing and combining device that creates multiple combined output signals, which are then coupled to provide a temperature-compensating voltage.
