Notice of participation in "High-Performance Materials Week" from September 30 (Wednesday) to October 2 (Friday), 2026.

Achieving the drying granulation of new semiconductor materials by utilizing spray drying granulation technology for electronic materials such as piezoelectric ceramics and ferrites!

"Spray drying" is a technology that instantly dries a liquid by spraying it in a drying chamber to create fine droplets, utilizing the surface tension of water to produce spherical, highly flowable granules. Based on our track record of granulating piezoelectric ceramics such as barium titanate and magnetic materials like ferrites to specified particle sizes and qualities through spray drying, we hope our granulation technology can contribute to the processing of semiconductor materials, and we will be exhibiting at the 2nd [Kyushu] Semiconductor Industry Exhibition! Our specialty is contract manufacturing, actively accepting trials and pilot production aimed at mass production, as well as drying and granulation tests in the early stages of research and development. Tests that are not intended for mass production are also welcome. We typically granulate ceramics such as silicon nitride, silicon carbide, and zirconia, as well as organic materials like surfactants and resins! Ceramics are mainly used for molding applications. [We respond to needs like these] ● I have a small amount of new material but want to somehow dry and granulate it. ● I want to take quantities in the range of several kilograms. ● I want to dry and granulate a small amount of materials in various types. We aim to leverage our experience in the semiconductor industry as well. *For more details, please download the materials.

Our company will exhibit at the "102nd Tokyo International Gift Show Autumn 2026" held at Tokyo Big Sight. At this exhibition, we will introduce various products made using sustainable knitting techniques, specifically <Whole Garment>, which utilizes only the necessary yarns to reduce resource waste. These products include bags, knit caps, gloves, lampshades, belts, and more. Additionally, we will demonstrate our design software <APEXFiz Design>, which enables everything from planning and design to color consideration, realistic fabric simulation, and 3D virtual sampling of products, showcasing new possibilities in knitting technology and solutions that lead to increased productivity. Booth: East 7-T44-26 (East Hall 7) Exhibition Content: APEXFiz Design (design software) SHIMA Datamall (digital content web service) yarnbank (comprehensive web service for yarn information) SHIMANAVI (e-learning system) Knit samples (whole garment knit accessories, three-dimensional swatches, etc.) <Contact Information> Tokyo Branch, Minami TEL: 03-3246-0511

[Instructor] Attorney Shinya Tsuchiya, Ishizaki & Yamanaka Law Office [Key Lecture Content] When various problematic behaviors arise from employees, such as poor work attitude, harassment, and lack of cooperation, if the employer mismanages the response, it can significantly undermine workplace order and operational efficiency, and there is also a possibility that the legal validity of disciplinary actions or personnel measures taken against the employee in question may be denied. To avoid such risks, appropriate and consistent responses based on employment regulations and internal systems are required. On the other hand, dealing with "problematic employees" can often place a significant psychological and practical burden on busy supervisors and HR personnel. In order to maintain smooth business operations, support for those responding and organizational preparedness have become essential in today's environment. In this seminar, we will systematically organize practical knowledge useful in the field by considering specific scenarios, focusing on the legal points and practical strategies to keep in mind when responding to various types of "problematic employees" that have been emerging recently.

We will be exhibiting at the "1st Chubu Food Industry Creation Exhibition '26" to be held at Port Messe Nagoya from November 4 (Wednesday) to November 6 (Friday), 2026. As a new addition to our lineup, we will showcase the "Cordless Sanitary Handy Pump," which is a product we started selling in April last year, alongside our "Compact Sanitary Handy Pump Model MHS." - Cordless! Portable anywhere! Easy to use! Simple cleaning! It is compatible with standard 18L cans and BIB (Bag-in-Box) and features a structure that allows for easy disassembly and cleaning. We would like to invite you to visit us at this opportunity. - Venue: Port Messe Nagoya - Our exhibition booth: Hall 1 "C-66"
