Latest Patents

One of Maekawa's latest patents is a power transmission mechanism. This invention features a design where a line connecting a center shaft of a reference gear member and a first shaft of a first planetary gear member, along with a line connecting the center shaft of the reference gear member and a second shaft of a second planetary gear member, form a specific angle α. The mechanism prevents rotation in one direction when a first carrier member and a second carrier member are relatively rotated to decrease the specific angle α. Additionally, a rotation prevention release unit is included to allow for the release of this prevention state when the carrier members are rotated in a direction that increases the specific angle α.

Another notable patent is an encapsulated cleanroom system. This system comprises a processing chamber and a storage section where the processing chamber is stored. During operation, the pressure in the storage section is either lower or higher than the pressures in the processing chamber and the exterior space. This innovative design effectively prevents the entry of outside gases into the processing chamber while also stopping the leakage of gases from the processing chamber to the exterior space.
