Suppressing the effects of external shock vibrations! A vibration isolation table for scientific instruments made possible by the high vibration damping performance of Rusk.

A vibration isolation table using porous cast iron rusk with rubber-like vibration damping properties. The surface of the installation table is damped with the rusk vibration isolation table, enhancing the vibration damping rate and reducing the impact of external vibrations. Data from comparative experiments between a general vibration isolation table and a rusk vibration isolation table, conducted by exciting a 2nd-floor concrete floor with a tapping machine (vibration machine for building tests), is currently available. In an environment where the measurement values of an electronic balance do not stabilize with the general vibration isolation table (values fluctuate due to vibrations), the RASK vibration isolation table stabilizes the values without fluctuation, resulting in measurable experimental outcomes.

• Weighing scale

A vibration-damping material that can be fixed in place and does not deform or displace, corresponding to nano vibrations and impact vibrations. It can be inserted and fastened in various locations for use.

A porous cast iron rusk with vibration damping performance comparable to rubber is coated with hard polyurethane resin to adapt to the usage environment. Since it is a sheet material, it can be processed into various flat shapes, and by fixing or sandwiching it near various sources of vibration, such as in machinery and parts vibration isolation, vibration isolation during the fixing of machinery to floors and walls, pipe supports, gaskets, and clean room floor vibration isolation, it can effectively reduce vibrations.

Soundproof door that reduces ultra-low frequency and low frequency! Suitable for tunnel blasting construction.

Using vibration reduction technology with porous cast iron RASK, we enhance the vibration control of conventional soundproof doors and significantly improve their sound insulation performance. It is capable of blocking ultra-low frequency sounds. In a nearby residential area, where blasting excavation noise reached around [87 dB] with standard soundproof doors, the introduction of RASK soundproof doors resulted in a reduction to [57 dB]. Since then, there have been about 27 instances of RASK soundproof doors being used in public works, demonstrating their effectiveness when needed.

Starting from October 2025, Panasonic's indoor units for office and store air conditioners will be renewed! In this renewal, all models will come standard with "100 times nanoe X." This not only enhances comfort with commercial air conditioning but also contributes to improving air quality. Additionally, improvements in installation efficiency to enhance on-site work productivity and a strengthened lineup to accommodate diverse spaces have been implemented. The new indoor units are equipped with high concentrations of nanoe X as standard! They demonstrate a high effectiveness in purifying indoor air during air conditioner operation, providing a safer and more comfortable environment for office and store users and employees. Furthermore, the center of the suction inlet and the center of the hanging bolt have been unified. This allows for the combined use of canvas ducts and panels, improving installation efficiency. If you have any questions or would like a quote, please feel free to contact us. We will fully support you in replacing your commercial air conditioning!

Kort Valuta Inc. (Head Office: Shibuya, Tokyo; CEO: Hideki Shibata) is pleased to announce that we will hold our next recruitment event, “Kort Valuta Night,” on November 26, 2025. This recurring event offers an opportunity for potential candidates to casually learn about our company culture and team atmosphere before applying. By lowering the barrier to entry and providing authentic insights from current employees, the event helps participants gain a more concrete sense of what it’s like to work at Kort Valuta. Since the event’s launch, approximately ten attendees have gone on to join the company in a range of roles — including marketing, customer support, and backend engineering.

Our company has been awarded the "Minister of the Environment Award for Climate Change Action for Fiscal Year 2025." This award is presented annually by the Ministry of the Environment to honor individuals and organizations that have made significant contributions to the mitigation and adaptation of climate change. Our efforts to balance energy conservation and comfort through "Akarina," as well as the initiatives we have undertaken together with the companies that have adopted it, have been recognized. We sincerely thank everyone who has supported and adopted Akarina for their invaluable assistance.

We are pleased to announce the development of the vehicle passage time prediction system "MS-VPP," which measures the speed of vehicles approaching construction sites using microwave sensors and informs the predicted passage time through signage and tablets. This system will be available to construction contractors starting in November 2025. ■Product Overview - "MS-VPP" detects vehicles approaching construction sites and measures their speed using microwave sensors, displaying the vehicle speed and the predicted passage time at specified locations on signage and tablets. It can also measure and display data for vehicles passing continuously. - The data control panel connected to the microwave sensor transmits the vehicle speed data and calculated passage prediction time via LTE. By utilizing microwave sensors, it enables accurate detection and speed measurement of vehicles even at night or in bad weather, and since data processing occurs on the receiving side without going through the cloud, information can be displayed without any time lag. - As a result, drivers of construction vehicles exiting from construction entrances and workers directing traffic can understand "how many seconds until a vehicle passes near the site entrance," thereby implementing safety measures in areas with poor visibility.
