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

Lenses for glasses, cameras, and other devices 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 extremely thin films, so we observed their structure in 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 microscopy 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 richly colored, necessary functional characteristics, artistic qualities, and design elements for the product's application are imparted. However, yellowing (discoloration) can occur due to the environment in which they are used, potentially compromising those characteristics. By quantifying transparency and color not through human 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 a light source passes through a transparent sample, and within an integrating sphere box, data on the transmitted wavelengths (transmittance) and converted color space data are 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 material for the negative electrode of lithium-ion batteries, additives for conductive plastics, inks, and CFRP. Our company evaluates the structural differences of carbon materials through 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 size differs, 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 disorder in the hexagonal structure, which is the unit cell of graphite, and the stacking of layers is more disordered. - In CB and activated carbon, the G-band peak is broader compared to graphite, and the full width at half maximum is larger. - 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.*

In civil engineering sites such as mountainous areas and construction sites, it may be necessary to use wooden boards on slopes or inclined access roads. Hyper CLT boards are civil engineering materials utilizing wood CLT, which can be laid not only on flat ground but also on sloped terrain. They can be used for temporary roads, access routes, heavy machinery entry paths, and measures against muddy conditions, creating a driving environment that takes advantage of the unique surface characteristics of wood. The 5×10 board weighs approximately 230 kg, and the 5×20 board weighs about 460 kg, making them lightweight and easy to install and remove even with small machinery, which is a notable feature for maneuverability in narrow sites. This wooden board is registered as a technology under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS system as "TH-250021-A," and can also be utilized for safety measures and innovative ideas in public works.

Metal cracks are one of the concerns in equipment maintenance operations. Repairs using conventional welding methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" or "secondary damage." Hinode Waterworks Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material with heat. Repairs can be performed even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized.

● The production time for cast 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 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! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.
