Latest Patents

One of Takaki's recent patents is for a **booster system**. This innovative system features a cooling temperature regulating unit designed to manage the temperature of an intermediate supercritical pressure liquid, which is cooled and produced by a primary cooling unit upstream of a pump unit. It includes a pressure detection unit that monitors both the inlet pressure of this liquid and the outlet pressure of a target supercritical fluid, ensuring efficient regulation based on the flow rate of a supplied cooling medium. Furthermore, the cooling temperature regulating unit adjusts the flow rate of the cooling medium by analyzing the pressure differential or ratio between the inlet and outlet pressures.

His second significant patent involves a **gradient information acquisition method, storage medium, gradient information acquisition device, and program**. This process consists of several steps: first, acquiring the speed of a rail vehicle; next, using an equation of motion to calculate this speed while factoring in the gradient of the vehicle's path. The method further includes obtaining parameter values indicating the gradient that minimizes the difference between measured and calculated speeds, ultimately allowing for accurate determination of the path gradient.
