Title: Power conversion device
Inventor: KISARA SHOGO
IPC: H02M7/48
Filed: 2019-04-10
Abstract: To cancel an off state of a switching element by a simple configuration, and to reduce possibility that latch of the off state is erroneously canceled by a control signal from a control part even when the switching element is latched in the off state due to excess current generated resulting from an abnormal control signal from the control part.SOLUTION: A driver IC turns off a switching element and latches an off state until a driving signal with a specific frequency is received from a microcomputer when excess current is generated in the switching element. An ECU (microcomputer) generates a driving signal with a frequency different from a predetermined frequency to be used for power conversion of a power conversion device as the driving signal with the specific frequency to be transmitted to a driving part in the case of canceling latch of the off state.SELECTED DRAWING: Figure 3

Title: Fuel storage system
Inventor: ANDO DAIGO
IPC: F02D45/00
Filed: 2019-05-24
Abstract: To solve the problem that a fuel tank is deformed when there is a big difference between a pressure in the fuel tank and atmospheric pressure outside the fuel tank, and the volume of the fuel tank is changed when the fuel tank is deformed, so the remaining amount of fuel stored in the fuel tank may not be accurately measured on the basis of the liquid level position of the fuel.SOLUTION: A control device calculates a reference remaining amount RA of fuel stored in the fuel tank. The control device calculates a correction amount CA to be applied to the calculated reference remaining amount RA of the fuel. The control device calculates the correction amount CA as a higher value in proportion as a pressure difference is greater which is a value obtained by subtracting a tank inner pressure from atmospheric pressure. Then, the control device calculates a value obtained by subtracting the correction amount CA from the reference remaining amount RA of the fuel, as a correction remaining amount CRA.SELECTED DRAWING: Figure 2
