Quality policy

We declare our quality policy that “In order to supply products with the best function and quality, we are continuing to implement research and development and will create original technologies. The quality management system should be built up based on the global standards. While taking the social responsibilities, we aim for the permanent development of the company and all related parties”.

We have created a quality management system confirming with ISO9010 in 1997 and upgraded to ”ISO9001:2000” in 2002.

Quality Management Efforts
  • As we stated in the policy description, In order to supply products with the best function and quality, Hokuyo obtained the international standard certification ISO9001. We are making efforts to continuously improve the quality system to satisfy our customers by supplying superior products with dependable quality.
  • As an enterprise, we fully maintain our social responsibilities to comply with the laws, regulations and consider the environmental effects when developing products.

Environment Efforts

  • Hokuyo intends to get ISO14001 of the international environmental management system and aims to become an eco-friendly corporation through the continuous system improvement, so that we can provide customers with earth-conscious products.
  • Hokuyo works toward realization of the energy saving society through the customers using our products by development of eco-friendly products and initiatives of automatic control systems.
    【Examples of Energy Saving by Using Our Products】

    ・Head-count and mobility measurement by the scanning range finder (SOKUIKI sensor)

    image The SOKUIKI sensor can control air conditioning and lighting as well as the opening and closing of doors at necessary times by obtaining information in advance such as the number and direction of movement of people within the set area.

    ・Factory Automation

    image Factory automation makes it possible to realize the shortening of hours, energy savings through efficiency in the process and a decrease of CO2 emissions.
    In addition, a reduction of human errors through automation leads to yield improvement and a lower level of defectiveness, thus making it possible to eliminate waste of resources and energy.

    ・Automation in Our Daily Life

    image Automation in our society has accelerated progressively, as seen in life-assistance type of robots used for shopping attendance and life support as well as in automated homes and commercial facilities. In such an automated society, Hokuyo contributes to the environmental improvement in the area of “Optics” of each automated device.

  • Hokuyo promotes lead-free solders in response to the Directive on RoHS and green procurement in order to realize earth-conscious products as a corporation.
    【Lead-free Solders】

    Solders are absolutely necessary for manufacturing electronics and electric devices and most of them have contained lead until recently. These days, however, it is necessary for countermeasures against lead to be argued for including lead-free solders, because lead contained in waste seeps into the ground and flows into the underground water, which may have an adverse affect on the human body. Hokuyo reduces environmental burdens by accelerating the use of lead-free solders.

    【Response to the RoHS Directive】

    Control instruments are not regulated by the RoHS Directive (as of October, 2006), however, Hokuyo is moving toward adaptation to the RoHS Directive continuously in order to satisfy customers’ requirements. For the products adapted to the RoHS Directive, please contact our sales representatives or the direct contact at Hokuyo’s website.

    【Green Procurement】

    Hokuyo’s green procurement means investigating the constituents of components in our products and content of regulated substances along with prohibiting and managing the object substances based on the guidelines formulated.

  • Hokuyo aims to make our workplace an energy-saving factory.
    We reduced power usage through more efficient air conditioning units and by covering the roof of the production building with a moss greening unit and light-blocking sheet.

    To suppliers from which Hokuyo purchases components

    For the purpose of reducing environmental burdens, acceptance of our customers’ requests and compliance with the legislation, Hokuyo investigates the content of the materials regulated and substances controlled by Hokuyo for our purchased articles. Basically, Hokuyo uses JAMP AIS Ver4.0 set forth by the Joint Article Management Promotion-consortium as the form for investigation. When the in-charge staff contacts you, please cooperate in answering to the investigation.
