Latest Patents

One of Tsuda's latest patents is a pressure detecting apparatus designed for detecting vehicle tire air pressure. This innovative device features a cylindrical housing that is mounted axially in parallel with a tire wheel. Inside the housing, a setting magnet, a rotor magnet, and a reversing magnet are arranged coaxially. The rotor magnet is supported by a shaft that can rotate and move axially in response to the tire air pressure introduced to a bellows within the housing. When the air pressure is normal, the rotor magnet is attracted to the setting magnet. However, if the air pressure decreases, the rotor magnet separates due to the movement of the bellows, rotates under the repulsion force of the reversing magnet, and is ultimately attracted to the reversing magnet. This operation reverses the position of the magnetic poles of the rotor magnet, which is then detected electrically by a magnetism detecting unit.

Another significant patent by Tsuda is a steering torque detecting device. In this invention, a steering torque is transmitted from a steering wheel side rotary member to a steering shaft side rotary member through multiple elastic bodies when the steering wheel is turned. These elastic bodies are positioned around the rotational center of the steering shaft, which has bending parts. The relative rotation between the steering wheel side rotary member and the steering shaft side rotary member is detected by detecting coils. These coils monitor changes in the reluctance of the magnetic circuit of the rotary members and the detecting coil, ensuring accurate detection of steering torque.
