One of Hatori's latest patents is a system for stabilizing the idling of vehicular engines. This innovative vehicular power steering system features on/off control means for managing a hydraulic fluid pump based on the steering effort applied to the steering wheel. Additionally, a sensing means detects vehicle speed, while a judging means produces an actuating signal when the control means activates the fluid pump and the vehicle speed is below a predetermined threshold. A solenoid valve, connected to the judging means, opens and closes a bypass passage that allows an air-fuel mixture to bypass a throttle valve, thereby stabilizing the engine's idling speed.
Another significant patent involves a steering effort sensor. This sensor arrangement utilizes a rolling element and cam groove configuration to induce displacement, which closes a switch to indicate torque application via the steering wheel. This design ensures an instantaneous drive connection between the upper and lower sections of the steering shaft arrangement, maintaining a desirable degree of torsional rigidity.
