Yasushi Endo

Title: Yasushi Endo: Innovator in Sensor and Switch Technology

Introduction

Yasushi Endo, an accomplished inventor based in Iwaki, Japan, has made significant contributions to the fields of sensor technology and switch design. With a total of four patents to his name, Endo's innovations reflect a keen understanding of electrical systems and materials.

Latest Patents

Among his latest inventions is an advanced infrared sensor. This device incorporates a pyroelectric element and a field-effect transistor (FET) housed within a high-frequency electric field and infrared radiation shielding case. To mitigate the impact of external high-frequency fields, a capacitor is strategically placed within the case, connected to the FET's drain and source electrodes.

Another notable invention by Endo is a variable capacitance type push-button switch. This switch features a movable member attached to a key stem and includes a holding member made from highly compressible elastic material. The design ensures that the movable electrode, which is both electrically conductive and flexible, can interact with two stationary electrodes via a dielectric film made of a fluoride-type synthetic resin, thereby varying the capacitance. The mechanism involves suspending pieces with pawls that engage the holding member, ensuring it maintains its upper position, while also allowing for its release to facilitate the contact between layers.
