• Testing Equipment and Devices

It measures viscosity under HTHS (High Temperature High Shear) conditions with high temperature accuracy.

**Product Overview** The USV high shear viscosity meter is a tabletop fully automatic rotational viscometer provided by PCS Instruments in the UK, designed to measure the viscosity of engine oil in conditions close to actual operation. **Features** It is capable of reproducing shear rates of 10^6 to 10^7/sec, which are observed in real engines. It can measure the complete temperature/shear rate distribution in approximately one hour. It enables accurate kinematic viscosity measurements in the high shear region, which is important in the automotive industry, and complies with domestic standards such as ASTM and CEC. **Main Evaluation Content** Shear rate distribution (viscosity × shear rate)

• Viscometer

The oil film thickness in the elastic fluid lubrication state is measured using the principle of optical interference.

【Product Overview】 The EHD Oil Film Thickness Tester is a tabletop fully automatic oil film thickness testing machine provided by PCS Instruments in the UK, and it is the successor model to the already proven EHD1. 【Features】 It is capable of measuring thinner films (minimum oil film thickness of 2nm) than conventional optical interference methods. By using the optional 3D-SLIM, it is possible to analyze the oil film thickness distribution across the entire contact area. 【Main Evaluation Contents】 Oil film thickness Stribeck curve (friction coefficient × rolling speed) Traction curve (friction coefficient × slip ratio) Oil film thickness distribution *Optional

• Coating thickness gauge

Reproducing rolling contact fatigue (RCF) due to pitching under lubricated/non-lubricated conditions.

【Product Overview】 The MPR Pitching Test Machine is a three-cylinder testing device provided by the UK company PCS Instruments, which generates pitching in a short time by increasing the contact cycles. 【Features】 Compared to general fatigue wear testing machines, it is compact and requires a smaller sample size for testing, making operation simple. In addition to stopping the test based on arbitrary parameters, it allows for interruption and resumption for surface observation of the test specimen. 【Main Evaluation Content】 Fatigue wear testing

<Title> Development of Gene Expression Control Technology through RNA Hacking In the latest presentation paper, we have utilized Abby. Associate Professor Yosuke Katsuta from Kumamoto University Graduate School of Advanced Science and Technology, Analytical Chemistry Laboratory (also co-founder of StapleBio), will be giving a presentation in an online seminar. He is working on the development of RNA hacking technology aimed at controlling gene expression by utilizing short nucleic acids named Staple to change the higher-order structure of target mRNA. He will present the latest data focusing on the results of cell experiments and animal experiments in the development of this technology.

● 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.

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 causing any thermal impact on the base material. 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.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! 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.
