Taiatsu Techno Corporation
1. Introduction
Taiatsu Techno is engaged in the design, manufacture,and sales of pressure vessels for equipment used inresearch and development. Our company is unique in that
all its design and manufacturing departments areconcentrated at the Taiatsu Engineering Laboratory in
Saitama City of Saitama Prefecture, allowing for close
communication between designers and engineers in themachining department and enabling us to incorporate
various user requirements for advanced technologicaldevelopment in tangible products. We have a product lineof pressure vessels that employ glass in the structure.
With much experience in manufacturing these pressure
vessels and through an accumulation of various tests, wehave succeeded in developing a window seal mechanism –for which we obtained a patent (No. 3354886) – thatallows for internal observations and optical measurements
under high temperatures and pressures. We believe ourlong track record and accumulated technologies onpressure vessels will provide reliable assistance for users
conducting advanced technological development in thefields of high-pressure instruments and equipment.

2. Expanding into Instruments for Researching
Supercritical Fluids
Taiatsu Techno first became involved in supercriticalfluids more than fifteen years ago while designing vessels
for withstanding high temperatures and high pressures.
Today we develop and design a wide range of vessels andsystems suitable for supercritical applications from thedemanding conditions of maintaining a water in asupercritical state to the relatively milder temperature andpressure conditions required for maintaining carbon
dioxide in a supercritical state. Through input from ourcustomers and tests conducted with actual equipment, weunderstand that the materials and seal packing used in thebody of vessels designed for supercritical fluids must betreated differently from those in common reactors. We
have incorporated this knowledge into our equipment
designs and have accumulated much expertise throughthe years in manufacturing supercritical instruments.
In response to requests from our customers, we began
to develop vessels and cells with windows that allow direct
observation of supercritical media, hiring dedicatedtechnicians for this purpose. As a result, we establishedand acquired a patent for a window seal mechanism that isreliable under high temperatures and pressures and thatfacilitates setup and operations. Many users have adopted
instruments employing our window seal mechanism, and it
is our hope that the capability to visualize supercriticalfluids under harsh conditions with such systems willcontinue to contribute to research on supercritical fluids.
In addition to responding to customer demands forvisual observation, we hope to provide sound solutions forcustomer issues through integrated management of ourknowledge and expertise on the design and manufactureof supercritical instruments. We understand that there area large number of possible combinations of pressures,temperatures, fluids, and control methods in supercriticalfields required by our customers. Therefore, our efforts in

R&D are not merely focused on the body of the pressure
vessel, the centerpiece of the research equipment, butalso on peripheral equipment and how to propose
optimum combinations and systems.

at AIST Research Center for Compact Chemical System)

We also introduced a compact process vessel designed
for supercritical experiments on carbon dioxide. Thevessel can be used prior to installing an actual system as
an initial step for assessing the research potential of thesupercritical fluid. Once provided with a rough descriptionof the experiment and its objectives, we can select thenecessary peripheral equipment and advise the customer
on the need for any new purchases other than thecompact process vessel, enabling the customer to begin
conducting experiments on a relatively low budget.
We continue to develop products to meet all ourcustomers’ needs in research on supercritical fluids, fromentry level to advanced, and are engaged in the design andmanufacture of pressure vessels that are safer and easier
to use.

3. Conclusion
Taiatsu Techno believes that safety issues must be
thoroughly addressed, even in relatively small pressure
vessels designed for testing and research. Throughconformance to regulations pertaining to pressure vessels
and repeated verification of operation and handlingprocedures, we are striving to create a safer environment
for users of high-pressure vessels. Furthermore, we areconstantly studying improvements to the clamp mechanismand exploring other systems for improving the safety of thetemperature control system without a loss in operability
in an effort to design and develop instruments that strike
the best balance between safety and user-friendliness.
