Notice of Participation in "SEMICON Japan" from December 9 (Wednesday) to December 11 (Friday), 2026.

Through diffusion bonding, complex shapes with internal flow paths can be realized! We are currently offering a collection of bonding case studies featuring materials such as quartz glass and pure molybdenum!

Diffusion bonding is a technology that directly joins materials together. Since it does not use adhesives or filler materials, contamination issues due to impurities do not occur. Additionally, it can suppress the occurrence of plastic deformation. By using diffusion bonding, it is possible to create hollow structures, internal flow paths, and deep holes with good straightness that cannot be achieved with conventional machining. We have a helium leak tester, so leak testing can also be conducted. 【Materials with Diffusion Bonding Achievements】 - Alumina - Aluminum nitride - Quartz glass - Silicon - SiSiC composite material - Pure molybdenum - Pure nickel We are also developing other materials. We are distributing a collection of processing examples using bonding, so please take a look. Shapes that were previously difficult to achieve may be possible by combining diffusion bonding with machining. If you have such parts, please feel free to contact Top Seiko. *The "Company Profile" was updated in December 2022. Please download it along with the "Bonding Processing Example Collection" from the link below.

Recently, we held technical training sessions for the MilkoScan FT3 at five locations nationwide. In this training, we provided a wide range of useful information for operating the equipment, including explanations of the principles and structure of the device, how to create measurement products, daily maintenance, and how to respond to issues when they arise. Additionally, this year we introduced new methods for utilizing digital services (such as FossCalibrator and IQX) and also prepared hands-on sessions where participants could experience operating the equipment using a PC. Thank you to everyone who participated. Please feel free to contact us with any questions after the training. ------- At Foss Japan, in addition to training sessions and workshops to ensure you can use our equipment with confidence, we hold many events throughout the year. In seminars and open houses tailored to specific industries and analytical techniques, we showcase Foss's latest analytical solutions. -------

We will be exhibiting at the "Monozukuri Fair 2026" held at Marine Messe Fukuoka from October 14 (Wednesday) to 16 (Friday). We will have a working model of a "small winch" powered by an electric driver equipped with our uniquely developed self-locking reduction mechanism "shoji-lock," and we will set up a corner where you can experience the actual lifting and lowering of workpieces. Please stop by. (Hall A, Booth Number AS-57)

[Lecturers] EY Strategy and Consulting Co., Ltd. Infrastructure Advisory Partner Kenichiro Fukuda Strategy Partner Ken Fujiyama Infrastructure Advisory Director Takashi Matsumura [Key Lecture Content] The water supply and sewage business is facing structural challenges such as facility aging, a shortage of workforce, and a decrease in revenue due to population decline. The government is promoting the introduction of Water PPPs, regional consolidation, and the digital transformation of water supply and sewage systems, marking a significant turning point in the way these businesses are operated. This change is expanding business opportunities for private companies in various areas, including operation and maintenance, pipeline renewal, digital technology, and the utilization of smart meters and data. Additionally, as a means of expanding business domains and enhancing competitiveness, there has been an increase in capital and operational partnerships and M&A between companies, leading to industry restructuring. In this seminar, based on the latest trends in policy and the market, we will introduce business strategies for private companies to enter and expand in the water supply and sewage market, including the use of M&A and capital operational partnerships, drawing on achievements from both public and private support.
