In the roll shop (the department that maintains rolls), tasks such as grinding rolls, maintaining seal parts, and servicing grinding machines are performed. Iron seal rings and rubber oil seals are used for the roll grinding machine parts, and both of these components experience significant wear and have a short lifespan, leading to time-consuming and labor-intensive maintenance issues. Issues and Points 1. The oil seals are inexpensive and can be replaced regularly, so we want to extend the lifespan of the seal rings. 2. Since the seal rings themselves are not very expensive, we would like to implement cost-effective measures. The inability to insulate these two areas leads to heat dissipation and losses. 3. Various tests have been conducted in the past, including hard chrome plating, carburizing treatment, and Dycron plating, but the results have not been satisfactory. (Both wear out in a short period, or one has a longer lifespan while the other has a shorter lifespan, etc.)

In the clean room, we were performing cleaning and coating operations as a pre-treatment, but there were frequent cases of foreign substances being discovered before coating. Although it was a clean room, the cleanliness class was not very high, and dust, which is a foreign substance, was re-adhering after cleaning. When foreign substances were found, it was necessary to clean again, which was a factor preventing an increase in production efficiency, so measures were urgently needed. Issues: 1. There are frequent occurrences of dust re-adhering to the products. 2. The cleanliness level in the clean room is class 100,000. 3. Dust accumulation is observed in the grooves and steps of the room walls, and turbulence is assumed to be occurring. 4. We want to separate the cleaning pre-treatment process from the coating process. 5. We want to bring the cleaned products into the coating room in a high cleanliness state.

To conduct a certain research, an experimental space capable of simulating a climate environment with a temperature range of 20 to 30°C and humidity of 40 to 60% is required. After requesting several companies to consider specifications and provide estimates, it seems that the costs significantly exceeded the anticipated budget. In general, the method commonly adopted to construct a constant temperature and humidity space requires the installation of an outdoor unit. In this case, there is more than a 50-meter distance between the laboratory and the location where the outdoor unit can be installed, resulting in enormous construction costs and duration. Issues: 1. I want to establish a testing environment, but the equipment introduction is very expensive. 2. I want to lower the budget but do not want to compromise on constant temperature and humidity conditions. 3. There is limited installation space. 4. The distance to the outdoor unit installation location is over 50 meters, which inevitably increases construction costs.

Due to the increasing sophistication of market demands for products, we have been consulted about the desire to perform cleaning and painting in a clean environment. Since cleaning and painting will be done using organic solvents, appropriate exhaust treatment is necessary. To keep the introduction costs down, it was essential to continue using the existing air conditioning equipment while managing the temperature. Issues: 1. The existing room is constructed with common building materials (gypsum board), which do not consider dust generation. 2. If airborne dust adheres to the products during cleaning and painting, it will reattach, making it impossible to meet high-quality standards. 3. A design is needed to ensure that the cleanliness does not decrease during entry and exit from the cleaned room and during the transportation of products. 4. Simply exhausting air will create negative pressure within the clean room, so it is necessary to supply clean air to maintain positive pressure overall. 5. We want to process the odors generated during cleaning and the paint fumes produced during the painting process with a single exhaust system.

Regarding the treatment of surplus sludge in the wastewater treatment facility, the surplus activated sludge was coagulated using chemicals with a dewatering machine, dehydrated with a cloth-type dewatering machine, and then entrusted to a contractor for disposal as industrial waste. The moisture content of the dewatered sludge cake was high, resulting in heavier sludge cakes and increased costs for industrial waste disposal, which was a concern (the industrial waste disposal contractor calculates costs based on volume and weight at the time of collection). 1. The operational management of the wastewater treatment facility is not good, and there is poor activation of the activated sludge due to fluctuations in the quality of the raw wastewater. (When the activated sludge is poorly activated, the amount of dewatered sludge increases due to phenomena such as sludge bulking.) 2. The capacity of the dewatering machine decreases due to insufficient coagulation reaction of the chemicals used for dewatering sludge. (This leads to an increase in weight because the moisture content of the dewatered sludge becomes high.) 3. The amount of dewatered sludge cake for disposal increases, leading to higher costs for industrial waste treatment. (Costs for industrial waste disposal contractors range from \30,000 to \50,000 per ton/m³.)
