Latest Patents

One of his latest patents involves a sophisticated surveying instrument. This invention features an output shaft of an ultrasonic motor that is attachably and detachably connected by a bolt to a lower end of a horizontal shaft of a frame unit. The frame unit is supported rotatably in a horizontal direction. A rotating plate is fixed to the output shaft, and a vibration generating component is formed on the outer circumferential portion of the rotating plate. A stator, which is in close contact with the vibration generating component via a predetermined friction torque, is rotatably provided on the output shaft. The stator is restricted on rotation by a whirl-stop unit, allowing ultrasonic vibration to be generated in the vibration generating component, thus enabling the output shaft to rotate.

Another patent also focuses on a surveying instrument, which comprises a frame unit capable of rotating horizontally via a horizontal rotation shaft. A telescope unit is provided that can rotate vertically via a vertical rotation shaft located in a recessed portion of the frame unit. Additionally, a vertical rotation driving unit connects to the vertical rotation shaft, and a whirl-stop unit is provided on the outer side of a side plate of the frame unit, connecting the vertical rotation driving unit and the frame unit.
