As the developmental application of the hybrid system provided with a gasoline engine and electric motors for a power plant, the hybrid snow thrower for general consumer use has been verified based on the key concept of improved handling and operability. The snow clearing system is driven by an engine and simultaneously generates power for two motors which drive the driving system. Computer-controlled travel motion together with automatic control of speed according to work load make for smoothness of travel motion and work alike. Operator load has been reduced significantly by mounting the driving levers on the driving system frame and placing the operating controls in a fixed location. In addition, the use of an electric operating system reduces the amount of force required to operate the various controls.

The recent progress of electronic control systems in vehicles is remarkable as evidenced by the development of electronic fuel injection systems,(EFI), automatic transmission control systems, and anti-lock brake systems,(ABS). The number of actuators for the systems has been increasing. Consequently, a need has been identified for a reduction in volume and number of the system actuators for control purposes. A composite magnetic material has been developed with the aim of miniaturizing magnetic solenoid valves for actuator applications. A composite magnetic material is such that both ferromagnetic and paramagnetic sections coexist within a single material, and can contribute to optimization of the magnetic circuit of a solenoid valve. This paper describes the development of a composite magnetic material, and its resultant characteristics.
