Title: Masaki Maruyama: Innovator in Fire Detection Technology

Introduction

Masaki Maruyama is a prominent inventor based in Machida, Japan. He has made significant contributions to the field of fire detection technology, holding a total of 4 patents. His innovative work focuses on developing systems that enhance the reliability and efficiency of fire detection.

Latest Patents

One of Maruyama's latest patents is an analog fire sensor. This system utilizes multiple sensors to produce analog data that corresponds to various physical states, such as temperature and smoke density, which are relevant to fire conditions. The system compares this data against a predetermined threshold level. If the threshold is exceeded, the data is transmitted to a central station, where a CPU assesses the possibility of a fire and predicts the remaining time until a fire condition is reached. An alarm is triggered when the predicted time falls below a preset interval.

Another notable patent is a fire sensing system that is protected from noise factors. This system produces fire detection signals with high reliability based on a quantity smaller than a predetermined standard. It includes a fire sensor connected in parallel with two semiconductor switching elements in independent power-supply circuits. The first circuit detects combustion quantities smaller than the standard, while the second circuit detects standard quantities. A substantial delay time is incorporated to absorb noise energy, ensuring that the system maintains proper conditions for alarm production.
