We would like to introduce a case study on active vibration isolation measures for liquid crystal substrate inspection equipment. During the installation of a large liquid crystal substrate inspection device (length measuring machine), a preliminary survey of the vibration environment of the installation floor revealed that it exceeded the allowable limits. This length measuring machine observes the line width of patterns optically and is sensitive to the vibration environment, so we implemented measures using an air servo active vibration isolation device. After the active vibration isolation measures were taken, we cleared the vibration allowable limits of the device and were able to establish a good vibration environment across all frequency ranges. [Case Summary] ■ Issue: A preliminary survey of the vibration environment of the installation floor for a large liquid crystal substrate inspection device (length measuring machine) revealed that it exceeded the allowable limits. ■ Measures: Installation of an air servo active vibration isolation device. ■ Effect: Cleared the vibration allowable limits of the device and established a good vibration environment across all frequency ranges. *For more details, please refer to the PDF document or feel free to contact us.

In a newly constructed office building, perceptible vibrations due to wind sway were occurring, and as a countermeasure, a TMD (Tuned Mass Damper) was installed on the roof to reduce the building's lateral sway. By installing the TMD, the vibration acceleration levels at the building's natural frequency were reduced by more than 6 dB (to less than half) in both the X and Y directions. Additionally, the building's damping ratio improved from 1% to 12%, significantly shortening the time until the vibrations converged. [Case Summary] ■ Key Point of the Measure: Installation of multiple small TMDs as a countermeasure ■ Measure: Installation of TMDs on the roof ■ Effect: Reduction of vibration acceleration levels at the building's natural frequency to less than half *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study on measures to address solid noise (noise) from air conditioning outdoor units. An air conditioning outdoor unit installed on the rooftop of an office building was generating solid noise on the floor directly below when it entered defrost mode. Although the outdoor unit was equipped with rubber pads for vibration isolation, the performance of the rubber pads was insufficient, allowing vibrations from the outdoor unit to be transmitted to the building structure, causing solid noise on the floor below. As a countermeasure, we proposed replacing it with a spring vibration isolation device. [Case Overview] ■ Key Point of the Countermeasure: Issues arise during special operation ■ Cause: Solid noise occurs because the compressor speed built into the outdoor unit increases during defrost mode ■ Countermeasure: Replacement with a spring vibration isolation device *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study on measures taken to address perceptible vibrations caused by the operation of a ceiling-mounted air conditioning indoor unit. In an existing 12th-floor clinic, perceptible vibrations were occurring on the examination room desk due to the operation of the ceiling-mounted air conditioning indoor unit below. In response to these vibrations, a measure was implemented to replace the existing vibration-damping rubber of the air conditioning unit with a higher-performance spring vibration isolation system, resulting in a reduction of desk vibrations. [Case Summary] ■ Key Point of the Measure: Significant vibration reduction effect achieved by switching to spring vibration isolation ■ Cause: The existing rubber hangers provided little to no vibration isolation, and the design of the examination room desk made it prone to shaking ■ Measure: Replacement with spring vibration isolation ■ Effect: Vibrations were reduced to the point where no further measures were needed on the desk side, and the building owner was very satisfied with the results. *For more details, please refer to the PDF document or feel free to contact us.
