Introduction

Kohichi Shimazaki is a notable inventor based in Mobara, Japan. He has made significant contributions to the field of wireless detonation systems, holding a total of 2 patents. His innovative work has paved the way for advancements in blasting technology.

Latest Patents

Shimazaki's latest patents include a wireless detonation system, a relay device for the wireless detonation system, and a wireless detonation method using the wireless detonation system. The wireless detonation system comprises a blasting operation device, a detonator, and a relay device. The blasting operation device is positioned at a distance from the blasting face and wirelessly transmits a first downstream signal at a first frequency. The detonator is placed in a blast hole within the blasting face and is equipped with a receiving coil to wirelessly receive a second downstream signal at a lower frequency. The relay device features a first transmitting-receiving antenna that wirelessly receives the first downstream signal, a relay processor that processes this signal into a second downstream signal, and a second transmitting-receiving antenna that transmits the second downstream signal.

Additionally, the wireless detonator includes a detonation side receiving antenna, a detonation side transmitting antenna, an initiator, and a detonation side electronic circuit. The receiving antenna captures energy to drive the electronic circuit, along with control and initiation signals. The electronic circuit then transmits a response signal and ignites the initiator based on the initiation signal, with a response frequency set between 100 MHz and 1 GHz.
