The Company

INC is an engineering firm; nearly 70% of our employees are engineers.

  • We actively search out the latest technology and skills through external courses and training. We are also active members of the Japan Society of Mechanical Engineers, Gas Turbine Society of Japan, Institute of Noise Control Engineering, Acoustical Society of Japan, Japan Society for Quality Control and several other academic societies.
  • Our employees hold many qualifications, including many first-class architects, first-class construction management engineers, certified measurers and pollution control managers.
  • Having mastered the basics and developed new technologies, currently we are mainly active in the following businesses:

1 .Consulting and Engineering

Our diverse services include surveying and measuring infrasound, noise and vibrations; formulating measures to prevent noise and vibration in plants and facilities; conducting environmental impact assessments after completion of new or expanded plants; and creating field surveys, literature retrieval, prediction analyses and noise contour maps. We do studies on prevention measures in these fields. In addition, we run simulations to predict the impacts of infrasound, noise and vibration on surrounding parts and conduct related testing and research.

2. Noise Control Equipment

INC offers full production support on various silencers, from design and manufacture through building and maintenance. Our silencers are for all range of infrasound and noises from gas turbines, boilers, ventilation fans, ships, wind tunnels and other sources.
Including various sound insulation package enclosures, soundproofed buildings, sound barriers and acoustic treatment structures, our measures account for performance of the equipment they are meant to protect.

3.Vibration Control Equipment

We offer everything from design through to maintenance of anti-vibration systems for preventing vibration propagation from compressors, press machines, casting machines, motors, pumps and piping.
We design, manufacture and build anti-vibration materials to effectively reduce solid-borne sounds in mechanical parking garages, apartment housing, railroads, roads and more.

4. Aircraft/Engine Operating Facilities

We offer full production and maintenance support for noise suppression systems and facilities for ground operation of aircraft.
In addition, we design, manufacture, build and maintain various types of test stands, instrumentation control systems performance analysis and evaluation systems to test performance of operating facilities and equipment for large fan engines, turbo jet engines, turbo shaft engines and other aero-derivative engines.

5. Test Facilities

We design, fabricate and install space utilization equipment and special specification research facilities. Our works include a drop capsule for microgravity experiments in Kamisunagawa, Hokkaido, development and testing equipment for aircraft engines, supersonic engine test systems for testing high altitude engine performance, microgravity measurement devices, bird strike and ice test facilities, various wind tunnels, electromagnetic levitation furnace test facilities, enhanced gravity generators for material production and vacuum chambers.
We also offer full production services for the anechoic chambers used in acoustic testing.

6. Environment and Diagnostic/Vibration Control Technology

  1. Active noise control system: Systems to analyze the frequency of a noise source and reduce the noise by producing a sound with the opposing phase to that frequency.
  2. Stratified air conditioning and ventilation system: A system to sequentially exhaust pollution and hot air by supplying air directly to work areas in plants and factories with contaminated air. Improves work area environments in short time and saves energy.
  3. Vibration control technology: We manufacture camera platforms and stabilizer mounts to allow use of high magnification cameras and parabolic antennas with the swing and vibration on helicopters, ships and land vehicles while operating. A few of our more notable products include:
    • Keel camera horizontal stabilizer mount system: for mounting to a railed television camera dolly on the ceiling of a domed stadium
    • Horizontal stabilizer for mobile tracking transmitter: for mounting to automatic tracking devices to send images from land vehicles and ships to direct communication satellites
    • Anti-vibration helicopter camera system: for mounting a camera to read license plates of automobiles from a helicopter flying 300 meters above
