Case Study: "Outdoor Exposure Measurement System with Data Transmission Function for Solar Cells" PDF

This is a system for evaluating the performance of multiple solar panels outdoors. To apply a load equivalent to that when connected to a power conditioner for each solar panel, an MPPT electronic load device is used during normal operation to operate at the maximum power point while acquiring data (voltage, current, power values). In this case, it is not necessary to synchronize the I-V curve measurement timing of each solar panel, so the measurement target is switched using a PV scanner, which is a measurement circuit switch, and measurements are taken with a PV Analyzer Gamma. A feature of this measurement system is that it automatically sends measurement data via email.

<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.
