Title: Yuriko Nishimura: Innovator in Communication Technology
Introduction
Yuriko Nishimura is a prominent inventor based in Kyoto, Japan. She has made significant contributions to the field of communication technology, holding a total of 2 patents. Her innovative work focuses on enhancing the efficiency and functionality of communication devices.
Latest Patents
Nishimura's latest patents include a Duplexer and Communication Module. This invention features a branching filter that has an antenna terminal which receives both signal waves and disturbance waves. It includes a transmission filter connected to the antenna terminal and a reception filter that receives a portion of the signal waves. The reception filter has a passband that operates at a frequency range higher than that of the transmission filter. Additionally, a disturbance wave resonator is connected to the antenna terminal and positioned closer to the antenna terminal side than both the transmission and reception filters. The resonance frequency of this resonator is within a frequency range smaller than the passband of the transmission filter, effectively addressing disturbance waves.
Another notable patent is for a Surface Acoustic Wave Element and Surface Acoustic Wave Device. This invention comprises an IDT electrode with an electrode finger on a piezoelectric substrate. The electrode finger is formed by laminating an intermediate layer and an electrode layer that has a higher coefficient of thermal expansion than the intermediate layer. The cross-section of the electrode finger is trapezoidal, widening nearer to the piezoelectric substrate, with specific angles formed to optimize performance.
