Section preparation using a microtome! Introducing examples of observing lens coating layers and multilayer films.

Lenses for glasses and cameras are coated with various layers. In the case of glasses, multiple coating layers are applied, including a hard coat to protect plastic lenses, an anti-reflective coat to reduce light reflection, and a UV coat to block ultraviolet rays. These layers are applied as very thin films, so we observed them from a cross-section. When observed with a scanning electron microscope (SEM), it was noted that a hard coat/multilayer film is applied on top of the lens substrate, and in the multilayer film, SiO and Nb films are alternately stacked. [Overview] ■ Cross-section preparation method - Prepared with a microtome - The lens removed from the frame was cut into small pieces and embedded in resin - Subsequently, a cross-section was prepared using a microtome, followed by optical microscope observation, SEM observation, and EDX analysis *For more details, please refer to the PDF document or feel free to contact us.

Digitizing transparency and color into numerical data! Objectively evaluating transparency rate and yellowing degree!

This introduction covers the evaluation of transmittance and yellowing (yellowness) using a color difference meter. By making the product's constituent materials transparent and rich in color, necessary functional characteristics, artistic qualities, and design elements for the product's application are imparted. However, yellowing (discoloration) may occur due to the environment in which they are used, potentially compromising those characteristics. By quantifying transparency and color not through human visual perception but as numerical data, objective evaluation becomes possible. [Overview] ■ Principles of color difference measurement and acquired data (XYZ Yxy color space) - Light emitted from the light source passes through the transparent sample, and within the integrating sphere box, data on the transmitted wavelengths (transmittance) and converted color space data is obtained. *For more details, please refer to the PDF document or feel free to contact us.

Measure the Raman spectrum! It is possible to obtain information about the structure and crystallinity of carbon materials.

Carbon materials include various types such as graphite, activated carbon, and carbon fibers, and are widely used in applications such as the active materials for the negative electrode of lithium-ion batteries, additives for conductive plastics, inks, and CFRP. Our company evaluates the structural differences of carbon materials using Raman analysis. In the case of carbon black (CB) and activated carbon, the G band peak becomes broader compared to graphite, and the full width at half maximum increases. This indicates that the crystallite sizes are different, with graphite having a larger crystallite size than CB and activated carbon. **Differences in Raman spectra due to carbon materials:** - Graphite shows a strong and sharp G band around 1580 cm-1. - It indicates the disruption of the hexagonal ring structure, which is the unit cell of graphite, and that the layered structure is more disordered. - In CB and activated carbon, the G band peak is broader compared to graphite, with a larger full width at half maximum. - Graphite has a larger crystallite size than CB and activated carbon. *For more details, please refer to the PDF document or feel free to contact us.*

We have released an introduction document for our cloud management system "Loglass." This document clearly presents the features and usage images of "Loglass," which streamlines management tasks such as budget formulation, performance management, forecast updates, and management accounting. Loglass centralizes data scattered across various systems and spreadsheets, reducing the effort required for collection, aggregation, and analysis, thereby supporting quicker and more accurate management decisions. Additionally, it helps address challenges such as the personalization of management tasks and increased workload through automation of data aggregation, history management, and real-time analysis functions. The document also includes actual implementation examples and the effects of implementation, showcasing results such as reduced workload, enhanced analysis capabilities, and improved decision-making speed. Companies considering promoting DX in management or reviewing operations centered around Excel and spreadsheets are encouraged to take a look.

We will introduce the implementation results of the sensor technology developed by the Hotron Group, which has been cultivated over more than half a century, through customer case studies. In addition to automatic door sensors, we also offer a wide range of vehicle detection sensors and nursing/care sensors. We have many implementation examples available, so please take a look at the case study page.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

Caught up in daily data entry, approvals, and inquiries, I want to improve but can't find the time to consider it. Such voices from the field are not uncommon. Even though it's clear that systemization is necessary, the reality is that people often get stuck on where to start and which products to choose. Common frustrations include "I spent time requesting materials and demos, but I'm not sure if it fits my company," and "After implementation, the inquiry contacts are scattered among different manufacturers, making it hard to connect quickly when issues arise." This moves us further away from the original goals of efficiency and reducing dependency on individuals. This is where the option of "agent implementation" comes into focus. Agents that handle products from multiple manufacturers have the advantage of providing unbiased comparisons and neutral proposals without favoring specific products. Even within the same category of systems, they can present the pros and cons side by side for a balanced evaluation. There is also a common misconception regarding pricing; in most cases, there is little to no price difference between direct sales from manufacturers and agents.
