Title: Mutsumi Negita: Innovator in Quartz Crystal Technology
Introduction
Mutsumi Negita is a prominent inventor based in Minowa, Japan. She has made significant contributions to the field of quartz crystal technology, holding 2 patents that showcase her innovative approach to engineering.
Latest Patents
Negita's latest patents include a quartz crystal vibrator electrode configuration. This invention features a quartz crystal tuning fork vibrator equipped with thin conductive film side electrodes. The design includes identically configured electrodes on both planar surfaces of the tuning fork tines, which are positioned peripherally along the lengthwise extents of the tines. The thin conductive film electrodes are strategically placed on the lengthwise side surfaces of the tines to electrically couple the similarly configured electrodes on the planar surfaces. The quartz crystal plate and the electrodes on the opposed planar surfaces are formed through a photo-etching process, followed by masking and sputtering a thin conductive film on the lengthwise edges to create the side surface electrodes.
