We would like to introduce an example of the installation of the "Hybrid Actuator." Aircraft operate with 3 to 4 hydraulic systems in parallel to enhance the reliability of the piping laid out within the fuselage. However, even with such safety measures in place, aircraft have historically experienced several crash incidents triggered by pipe ruptures. The Boeing B777 passenger aircraft has adopted the hybrid actuator and has removed all piping, which was the source of accidents. However, it does not completely eliminate the use of servo valves. To remotely control this "Hybrid Actuator," the B777 uses electrical wiring, referred to in aviation terminology as fly-by-wire, and the method of remote control using light is called fly-by-light. Our steering system is a groundbreaking system that has removed not only the piping but also the control valves, and we have already obtained patents in the United States, the United Kingdom, and Japan. *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce examples of the installation of "Hybrid Actuators." Passenger transport vessels are becoming increasingly faster, and even cargo ships are advancing in speed, with three types of high-speed vessels being prototyped under the "Super High-Speed Cargo Ship Techno Superliner Project." As speeds increase, it is necessary to lift the hull above the water surface to reduce water resistance. Therefore, posture control using underwater wings becomes essential, and the demand for the DDV servo control method is increasing. The energy consumption required for posture control of large hulls is enormous, so even a slight loss of energy significantly impacts operating costs. By adopting the DDV method for this fin stabilizer, energy consumption will be drastically reduced. *For more details, please refer to the PDF materials or feel free to contact us.

Here is an example of the installation of a "hybrid actuator." The steering system of a vessel typically uses a servo control system with a servo valve or proportional electromagnetic control valve. The steering system using a hybrid actuator demonstrates control characteristics that are comparable to traditional systems, and with four times the output and a volume of about 1/8, it has enabled a significant reduction in the size of the steering room. Furthermore, the improvement in steering speed has made roll stabilization operations possible. 【Case Study】 - Installed on the training ship "Shioji Maru" of Tokyo University of Marine Science and Technology - Results have been presented at the joint symposium of the Society of Fluid Measurement and the Society of Fluid Control *For more details, please refer to the PDF materials or feel free to contact us.

Here is an example of the installation of a "Hybrid Actuator." One of the most outstanding characteristics of the DDV method is synchronous operation (synchronization), and it is extremely difficult to open and close a wide gate while keeping it level.

Here is an example of the installation of a "hybrid actuator." It is installed at the Fukuyama Steel Works of Nippon Steel Corporation and is used for controlling the flow of molten steel in the bloom (special steel) continuous casting equipment. The viscosity of molten steel heated to 1,600°C is lower than that of water, making it a very difficult liquid to handle, and controlling its flow requires extremely fast responsiveness. This device demonstrates control performance that is at least equal to that of conventional servo valves, reducing the annual electricity costs from 5 million yen to just 90,000 yen. Furthermore, due to the very small total amount of hydraulic oil, it is exempt from fire safety regulations, allowing the use of flammable oil even in hazardous locations, thus freeing us from the complexities of waste oil disposal and environmental conservation measures.

Here is an example of the installation of the "Hybrid Actuator." The parallel link motion base has six axes arranged in parallel, resulting in very high rigidity. This mechanism can perform six motions simultaneously, and its structure is extremely simple, allowing for weight reduction. By using a "Hybrid Actuator" in the parallel link motion base, it is possible to eliminate piping work while still being hydraulically driven, making it an ideal machine tool that requires almost no assembly or adjustment processes. Currently, the parallel link mechanism that has been announced requires a total of 12 pivot points, but our company has developed a mechanism that reduces the number of pivot points to six, significantly improving the accuracy of table posture control. As a result, there is a reduction in the number of program steps, which in turn enhances control speed, leading to a dramatic improvement in the machining accuracy of the machine tool. *For more details, please refer to the PDF materials or feel free to contact us.

The hybrid actuator "HySerpack" developed by our company does not require a control valve and can control thrust and rod position with high precision. It rotates a hydraulic pump with a servo motor, and the forward and reverse rotation of the servo motor controls the discharge direction of the hydraulic pump. Since there is no need for a directional control valve and the discharge amount of the working oil can be controlled by adjusting the rotation speed, oil quantity control is also unnecessary. It combines the features of an electric actuator with the high rigidity of a hydraulic cylinder. 【Features】 - No hydraulic source equipment, control valves, or piping required; no hydraulic construction needed. - When the actuator is stopped, the motor and pump also stop, significantly reducing power consumption. - Compact, high-functionality, high-output, high-precision, low-noise, and high-efficiency. - No cooling drainage, and no disposal treatment for working oil is required. *We offer explanatory materials on the hybrid actuator and product examples such as servo presses that incorporate it!
