Our new I-V curve tracer can measure "high-efficiency solar cells" such as N-type, half-cut cells, and N-type back contact.

Recently sold high-efficiency solar cells PVA14300R, PVA18340, PVA11270, and PVA14301 can be measured using I-V measurements.

In recent years, there have been reports of cases where I-V curves cannot be measured for high-efficiency solar cells (such as N-type and half-cut cells) using products from other companies or the old model Epsilon 1000 (PVA14300) PV analyzer. However, it is possible to measure them using the current Epsilon 1000 (PVA14300R), Epsilon 1500 (PVA18340), Gamma series (PVA11270, PVA14301), and Delta (PVA11272) PV analyzers, which will be explained in this document.

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.

Are you struggling to explain "safety" to the client using just drawings? - The risks in blind spots are difficult to convey to the client through drawings alone. - Safety measures often become a target for cost reduction, making it hard to communicate their necessity. - There is a concern that the client might say, "It's more dangerous than I thought," after completion. Risks that are visible to design professionals are not easily understood intuitively by clients who are outside the field. This document is not just a simple explanation of sensor functions; it is a guide to visually explain "why sensors are necessary in that location." It can be used directly as explanatory material for the client. Here are three key points for utilizing this document: 1. Visualization of Risks Blind spots during vehicle departure and contact risks within the site are illustrated clearly. 2. Clarification of Selection Criteria A comparison table outlines the differences between complex sensor types such as infrared, ultrasonic, and loop coils. 3. Diagram of System Configuration It illustrates not just the sensors alone, but how they combine with components like rotating lights and control panels, providing practical assistance for electrical equipment design. Please make use of this to prevent "rework after completion" and "accident risks."

In facilities operating nurse call systems, we have made the bed exit sensor wireless, allowing it to notify in conjunction with the nurse call system. By simply connecting the mat sensor "Foldable Thin Matt-kun," the body movement call "Ugo-kun," and the wheelchair body movement call "Ayumi-chan" to the transmitter HB-RS, you can make the bed exit sensor wireless. The infrared sensor "Just Place Pole-kun" has the transmitter HB-RS built-in. This helps prevent accidents caused by falls, slips, or wandering, contributing to the efficiency of medical operations. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ The bed exit sensor notifies wirelessly in conjunction with the nurse call system. ○ Up to 5 transmitters can be registered with a single receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.
