Latest Patents

One of Katagata's latest patents is a railway platform door device. This device is designed to reduce the time required for replacement operations when a panel-shaped portion of a door is damaged. The platform door device consists of a door and a driving mechanism that allows the door to move forward and backward, effectively opening and closing a gate on a platform. The driving mechanism includes a motor, a rotation body that is rotated by the motor, and a driven body that moves the door according to the rotation of the rotation body. The door features a panel-shaped main body and a base segment that is detachably joined to the main body and attached to the driven body.

Another notable patent is for an electrophotographic apparatus that prevents toner from attaching to a photosensitive drum. At the start of the rotation of the photosensitive drum, the rotation of a developing roller is kept stopped until a predetermined point on the photosensitive member reaches the development position. After this time elapses, the developing roller is rotated. Additionally, when the predetermined point passes the transfer position, a roller cleaning voltage is applied to a transfer roller, which has the same polarity as the charge polarity of the toner.
