Abstract: A noise generation cause identifying method and a noise generation cause identifying device are provided. A response correcting process corrects a sound signal obtained through a sound signal obtaining process based on obtained model information so that a frequency response of the obtained sound signal approaches a frequency response of a learning sound signal. A variable obtaining process obtains a variable output from a map by inputting the corrected sound signal to the map. A cause identifying process identifies a generation cause of a sound picked up by a microphone using the variable obtained through the variable obtaining process.

Abstract: An electric pump is provided, which may include a motor unit including a rotation shaft, and a pump unit including a rotor having a vane groove accommodating a vane and coupled with the rotation shaft, and including a pump plate including an external wall portion and a cam ring having a cam surface on which the vane slides, and a bottom lid portion provided in the pump plate and being integrally formed with the external wall portion and the cam ring, and a connection unit being provided between the external wall portion and the cam ring to connect the external wall portion and the cam ring and protruding in a direction away from the bottom lid portion, and the connection unit is integrally formed with the external wall portion, the cam ring, and the bottom lid portion.

Abstract: An electric pump including a motor unit including an end cap attached to a motor cover, and a power supply bus bar having wiring inserted therein is integral with the end cap; a pump unit including a rotor having a vane groove for receiving a vane and connecting to the rotation shaft and also including a pump plate having a cam ring; and a cover covering the pump unit from a side opposite to the motor unit and provided with a connector box surrounding an insertion recessed portion into which the power supply bus bar is inserted. The cam ring has a penetration hole through which the power supply bus bar and wiring can be inserted, the wiring being electrically connected to a connection unit provided in the insertion recessed portion.

Abstract: An electric pump includes a pump; a motor having a motor shaft, the motor shaft being connected to the pump to drive the pump; a support member which is arranged between the pump and a front end portion of the motor, the front end portion of the motor being a motor shaft side, the support member supporting the pump and the motor when the motor shaft penetrates the pump; a motor cover which covers the motor, the motor cover having a closed-end cylindrical shape, and an opened end side of the motor cover being fixed to the support member; and an elastic member which is in a state of being compressed positioned between a rear end portion of the motor and a bottom portion of the motor cover. The motor is supported by the support member as being urged thereto by the elastic member.

Abstract: In a throttle device that includes a housing having an intake passage, a throttle valve to regulate the flow rate of the air flowing through the intake passage by rotation inside the intake passage, and a drive unit rotate the throttle valve, the drive unit is cooled with good efficiency. In a throttle device that includes a housing having an intake passage, a throttle valve to regulate the flow rate of the air flowing through the intake passage, and a drive unit to rotate the throttle valve, there is provided a cooling unit to directly cool the drive unit.
