Latest Patents

One of Sakai's latest patents is for an electric motor. The invention aims to enhance the layout properties of components arranged on the brush holder. It features power feeding terminals that are flat and extend in the axial direction of the armature shaft. These terminals are arranged side by side in the width direction at one end of the brush holder. Additionally, a condenser is placed between the power feeding terminals and the armature shaft. The design includes a power supply circuit that connects the terminals to a leaf spring brush, which is grounded through a grounding stay. A choke coil is also integrated to minimize noise in the power supply circuit.

Another significant patent is for an automatic opening and closing apparatus for vehicles. This invention focuses on creating a thinner design for the apparatus. An outer rack is attached to a stay fixed to the vehicle, allowing it to move freely in the axial direction. The stay's thickness is designed to be smaller than its width, with a cross-sectional shape that is substantially thin and convex. The outer rack is formed in a thin C cross-sectional shape, optimizing the thickness of the slide mechanism for the gear with rack gears aligned in the axial direction.
