Notice of advertisement publication in the Chemical Industry Daily "Shiga Special Feature" October 31, 2023 issue.

The liquid contact materials have been upgraded to SUS, PTFE, and FFKM, allowing for a wider range of compatible liquids compared to our previous model (CHD-20A)! Suitable for solvent transfer in areas where open flames are prohibited.

**CHD1 Series** CHD1-20ASUS (for solvents) CHD1-20ASUS-V (for solvents / with ball valve) CHD1-20ASUS-N (for solvents / with gun nozzle) ● Oil-free air motor type ● Lightweight and compact body ● Inexpensive **Features** ● Safe and secure due to air drive ● Dedicated for JIS standard 200L closed drums (large cap G2) ● For low viscosity solvents (below 100cP) ● Discharge rate of 20L/min (with nozzle) ● Discharge only **Applications** Used not only in metal plating factories and semiconductor manufacturing but also in chemical plants, pharmaceutical warehouses, and other sites. Additionally, it is used in water treatment, pharmaceuticals, laboratories, schools, and hospitals. For areas with high volatility, high flammability, explosion-proof zones, and no open flames, please use the air-operated model (CHD1-20ASUS-N). **Suitable for use in the following areas!** ■ Lithium batteries (secondary batteries) ■ Dyeing, semiconductor, disinfectant manufacturing, automotive, and electrical appliance factories ■ Surface treatment in metal plating factories ■ New energy sector **Compatible with the following liquids!** ■ Alcohol ■ Thinner ■ Acetone ■ Methanol ■ MEK, etc.

For applying oil and adhesive! Also for filling varnish and grease!

*When using adhesive, only those that do not damage the material are allowed. For details, please contact us.* APP-C1-AL (for oil) APP-C1-SUS (for solvents) ◎ The discharge pipe has a large diameter to accommodate high-viscosity oils and solvents ◎ Grease up to #3 consistency can be discharged ◎ The suction pipe has been modified in two places for efficient discharge when switching between closed cans, etc. ◎ Can be shared between different diameter cans such as pails and one-gallon cans *Benefits* ■ Capable of discharging high-viscosity liquids (below 10,000 cP) ■ The spring mechanism allows the pipe to reach the bottom of the can, minimizing residual liquid ■ Can transfer to high places or long distances under high pressure *Features* ■ Sealed pressurized and discharge-only ■ Entirely pressurizes one-gallon cans or pails ■ Continuous operation possible ■ Lifting capacity of 30m ■ Usable with air compressors of 1 horsepower (0.75 kW) or more

● The production time for casting prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly creating sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or variations in dimensions, can be created in a single molding process. This allows for the verification of multiple types in a short period.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without affecting the base material with heat. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

Dear Sir/Madam, I would like to express my congratulations on the continued prosperity of your company. Thank you very much for your exceptional support. We would like to inform you that our company will be closed for winter holidays during the following period. We apologize for any inconvenience this may cause and kindly ask for your understanding. 1. Winter Holiday Period From Thursday, December 28, 2023, to Thursday, January 4, 2024. 2. Business Operations After the Winter Holiday Period We will resume normal operations from Friday, January 5, 2024.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm. Please feel free to contact us for more information!

By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.
