Announcement Regarding the Successful Bid for JAXA General Competitive Bidding"Production of Grand Model and Flight Model for Cell Biology Experiment Facility:
Quick Connect Disconnect Device (QCD)"HIROSHIMA, JAPAN – May 10, 2024- JMS Co., Ltd., (President: Ryuji Katsura, hereinafter called “JMS”),
today announced that JMS successfully won the tender of "Production of Grand Model and Flight Model for
Cell Biology Experiment Facility: Quick Connect Disconnect Device (QCD)" through the generalcompetitive bidding held by Japan Aerospace Exploration Agency (hereinafter called "JAXA").
JMS’ product of Closed System Drug Transfer Device named "NEOSHIELD" (hereinafter called"NEOSHIELD") contributes to the safe preparation of anticancer drugs in the medical field. JMS judgedthat the distinctive technology of "NEOSHIELD" could be applied to the exchange of cell culture media inspace and conducted the modification for developing the product to meet the specifications of design for cellbiology experiment facility: Quick Connect Disconnect Device (hereinafter "QCD") required by JAXA.
<Features of "NEOSHIELD"> Closed System
This system prevents any contamination and mixture from the external environment or leakage to theexternal environment by preventing the chemicals from contacting with the external air when connecting
or disconnecting the flow paths.
Simplified Operation
This system enhances safety through the intuitive operation for connection and disconnection.

The mechanism keeps the rubber plate
and the slit of the rubber cover adheredand does not open until connecting.

Based on the design of "NEOSHIELD," JMS completed the production of the engineering model with thebasic design of the QCD specification for cell biology experiment facility required by JAXA to collect datafor proceeding to the detailed design phase. JMS has now successfully won and signed the contract for theproduction of the ground model and flight model, which is the next stage of the project< Designing key aspect of the Engineering Model>
 Miniaturized to be fit for the limited area of experiment on space station.
 Modified specifications to adjust to the structure of cell biology experiment facility used at JAXA.
 Maintaining the quality of the function of closed system at the same level of medical device.

Developed cell biology experiment
facility QCDJAXA has selected two research projects in the field of regenerative medicine to demonstrate the technologyof the cell biology experiment facility aiming to launch and space experiments after January 2026. QCD
produced by JMS will be used in these research projects. JAXA is also working to increase the demand foruse of the Japanese Experiment Module "Kibo" by the private sector, so it is expected that more researchers
will use the QCD produced by JMS in the future.

JMS will continue to contribute to the development of medical and scientific technology by leveraging oneof its core technologies of the closed system.
※1. QCD (Quick Connect Disconnect): A mechanism to quickly and safely connect and disconnect devices.
※2. Referenced from JAXA website as follows: https://humans-in-space.jaxa.jp/faq/detail/000491.html【Engineering Model】
A model to acquire data to confirm the design for the next detailed design step after producing based on thebasic design and confirming the design validity by providing for functional, performance, and environmental
tests. The model has almost the same specifications as the actual launch model, except for the quality andreliability of parts. Several models could be produced depending on the test purpose.
【Grand Model】
A model to be modified from the engineering model depending on the conditions of testing and training.
【Flight Model】
A model produced by the same design and manufacturing method as the prototype model that has passed thecertification test and is actually launched into space. For this model, it is tested to confirm that it has thequality required for launch. As the design has been confirmed by the certification test, it will be tested toconfirm that there are no defects caused by the manufacturing process in the receiving test by performing asimulated orbital environment test.
