Title: Hidetoshi Ooiwa - Innovator in Fuel Storage Technology

Introduction

Hidetoshi Ooiwa is an inventor based in Anjo-city, Japan. He has made significant contributions to the field of fuel storage technology. Although he currently holds no granted patents, his innovative ideas are reflected in his latest patent applications.

Latest Patent Applications

One of Hidetoshi Ooiwa's notable patent applications is for a **FUEL STORAGE DEVICE**. This device includes a fuel tank designed to store liquid fuel, which is fed through a fill opening of a vehicle. The fuel tank consists of a tank case and a separating film. The tank case has a projecting shape in section and defines a two-tiered upper-lower fuel storage chamber when disposed in the vehicle. The separating film is deformable within the tank case and is impermeable to liquid fuel in the storage chamber. The fuel storage chamber comprises a primary fuel storage chamber and a secondary fuel storage chamber. The primary chamber is partially surrounded by the separating film and communicates with the fill opening. The secondary chamber projects toward the upper side of the primary chamber and communicates with the fill opening only via the primary chamber.

Another significant application is for a **VAPOR FUEL TREATMENT APPARATUS**. This apparatus features a control part that conducts pulse width modulation control for a first valve and a second valve. This control ensures that the sum of the first flow rate of fluid flowing through a first passage and the second flow rate of fluid flowing through a second passage aligns with a target flow rate. When the target flow rate is less than the sum of the maximum flow rates of both passages, the control part adjusts the control timing of the signals driving the valves to differ from each other.

Conclusion

Hidetoshi Ooiwa is an innovative inventor whose work in fuel storage technology showcases his potential to contribute significantly to the field. His latest patent applications reflect his commitment to advancing technology in this area.
