Title: Three-phase power conversion system for electric railway
Inventor: TANAKA KOTARO
IPC: H02M7/48
Filed: 2021-03-24
Abstract: To provide a three-phase power conversion system for an electric railway capable of appropriately protecting the system while suppressing an influence on a sound feeding circuit when a temporary heavy current is generated even when operated in conjunction with a three-phase railway power source.SOLUTION: A three-phase power conversion system for an electric railway includes a control device for controlling a conversion operation from DC power to three-phase AC power by an inverter. At normal time when the current flowing through a plurality of feeding circuits is determined to be lower than a predetermined value, the control device controls the operation of the inverter so that predetermined effective current and reactive current are supplied to the plurality of feeding circuits by setting a predetermined current command value on the output of the inverter. At the time of large current generation when the current flowing through any one of the feeding circuits is determined to be a predetermined value or higher, the control device controls the operation of the inverter so that the current output from the inverter becomes low by lowering the current command value to a lower level than at normal time.SELECTED DRAWING: Figure 2

Title: Splash salt collection from seawater and magnetic collection method of lithium
Inventor: KAWAI NOBUO
IPC: C01D15/04
Filed: 2021-03-15
Abstract: To provide a magnetic collection method of lithium instead of a conventional splash salt collection method considering a situation such that salt is an essential ingredient for sustaining human life, in Japan, attempts have been made to extract salt from seawater since ancient times, its operation requires a large ground, vast labor and large heat energy, similarly, seawater contains precious lithium, which is almost inexhaustible, but it is difficult to separate and extract it and it was not profitable.SOLUTION: This is a method for efficiently separating and collecting salt from seawater. When seawater is blown into a spray, foam-encased salt crystals reach farther and can be collected with a cloth, net, or other collecting device, dried, and purified to produce natural salt. When a strong magnetic field is applied in the process prior to spraying seawater, lithium atoms, which have paramagnetism, become more magnetic, so they are adsorbed and collected by electromagnets in the lithium magnetization collection method. Since irregular rare metal particles adhere to the electromagnet, they are isolated and refined to extract only lithium.SELECTED DRAWING: Figure 1
