Latest Patents

Hara's latest patents include a tone arm assembly designed for record players. This assembly features first and second electro-magnetic motors that allow the tone arm to swing in both vertical and horizontal directions relative to a record disc on a turntable. The control circuit manages the motors to move the tone arm from a raised inoperative position to a lowered playing position, and vice versa, based on control signals.

Another significant invention is the turntable assembly for phonograph records. This assembly consists of a rotatable turntable with a rubber or elastically flexible sheet that covers a substantial portion of its upper surface. The sheet is secured along its edges, creating at least one sealed interior space filled with a viscous liquid. This design provides a cushioned, vibration-damping surface that conforms to warped records. To prevent liquid accumulation when the turntable is not level, the interior space can be divided into multiple compartments, each potentially containing absorbent material to manage the viscous liquid.
