Gain knowledge and benefit! Technical materials for researchers useful for starting up and operating vacuum devices.
Are you experiencing trouble without understanding the basics? Designers should carefully consider the design review items for the installation, operation, and maintenance of vacuum equipment from the user's perspective. To do this, designers, manufacturers, and operators themselves need to understand the vacuum equipment and the materials and surfaces of the work targets. Furthermore, they must embody gas molecules, excited particles, and charged particles to comprehend their behavior in the gas phase and on the materials' surfaces. Then, let's determine what factors limit the work results and advance the development and improvement of design, manufacturing, and operation. [Features] - For equipment designed with the premise of not baking after assembly, pre-baking holds significant importance. - Equipment or parts that were thought to be unsuitable for use due to high outgassing may be usable at the desired pressure through pre-baking of the components. - Even if baking is assumed, pre-baking the equipment and parts in the vacuum furnace before assembly can shorten evacuation and aging times.

Company information
The history of Kitano Seiki is also a trajectory of continuous contribution to cutting-edge research fields through the provision of precision instruments for research and development. In November 1958, we were established as a company specializing in the design, manufacturing, and sales of precision instruments. Since then, we have developed and manufactured experimental equipment aimed at research institutes in universities and government agencies, as well as basic research laboratories in private companies, earning high praise for our excellent quality and reliability. In particular, in recent years, we have been at the forefront of ultra-high vacuum and ultra-low temperature technologies, which are essential in industrial fields such as new materials, nanotechnology, flat panel displays, high-temperature superconductivity, solar cells, nuclear power, and space development. We have accumulated abundant technology and know-how in creating experimental environments and have linked this to the development and provision of equipment that condenses advanced performance and functionality. At Kitano Seiki, we always work closely with researchers, our users, to design and develop equipment that accurately supports research and development objectives. With a consistent system from parts manufacturing to various processing, assembly, inspection and testing, equipment setup, and after-sales support, we provide high-quality products and a conducive experimental environment for quality research and development.
