Plan A of the quality assurance system

We implement a wide range of initiatives to ensure reliable quality in all processes, ranging from planning and development through manufacture, sale, and maintenance, to deliver to all customers products that transform invisible risks into visible security, at any time and in any situation.

The Planning and Development Committee deliberates on and makes decisions concerning development themes and pursues development efforts based on various inputs, including customer needs.
As an operational structure for product development processes, the Company deploys a project-based structure involving personnel in charge from the Sales Division and Development Division.
Final prototypes completed by a project group are subject to quality assessment testing (validity confirmation) by quality assurance sections to confirm they meet the specified design requirements.


We proceed to the mass production stage only after evaluating the initial production of new products for which validity has been confirmed.
The mass production process involves procuring necessary components from our supply chain and meeting work standards that specify in detail matters such as assembly and inspection methods.
Products passing shipping inspection are stored for specific periods of time in our product warehouses, in accordance with the specified storage conditions, then shipped in response to customer orders.


Sales staff with deep knowledge of our products propose solutions addressing various aspects related to products suited to individual users through the development of system software.
We assign field engineers to maintain our products at each service station. Given the need among maintenance staff for high technical skills and decision-making capabilities, we certify as field engineers only those individuals who have completed specialized training and have been assessed to possess the necessary skills.
