Latest Patents

Shiratori's latest patents include innovative designs such as an encoder, lens-implement, and digital camera. The lens-implement patent describes a configuration where all members of a lens-implement are arranged in a rectangular space of a main lens frame. A lens prism is fixed, and three movable lens frames for zoom and focusing are inserted into two guide shafts. The image capturing lens is arranged top-to-bottom, occupying the horizontal ⅓ portion of the rectangular space, with the image capturing device positioned at the foot portion. Additionally, a zoom motor is located at the back of the lens prism, along with a zoom shaft cam, diaphragm/shutter, focusing ultrasonic linear motor, and a magnetic sensor arranged along the lens frames.

Another notable patent is for a vibration wave linear motor. In this design, coupled driving contacting parts are provided on the top and bottom of a vibrator unit. Two upper and lower guide shafts, which contact concave parts of the coupled driving contacting parts, are supported by erecting parts of a supporting part. The lower guide shaft is pressed upward by spiral springs, allowing the two guide shafts to press and sandwich the vibrator. By applying alternating current voltages with different phases to the vibrator unit, a vibration wave is generated, resulting in elliptical rotation vibrations in the driving contacting parts.
