Abstract: A control device for a motor-driven fuel pump adapted for an internal combustion engine is provided. The internal combustion engine including a fuel injection valve configured to execute multistage injection in which fuel is injected into a cylinder multiple times in one combustion cycle. The fuel pump includes a cylinder, a mover in the cylinder, and an electric actuator configured to move the mover. The control device is configured to cause the fuel pump to discharge fuel in a period between an end of a multistage injection from the fuel injection valve and a start of a next multistage injection, and keep the fuel pump from discharging fuel in a period during which the multistage injection from the fuel injection valve is executed.

Abstract: A PCVD apparatus includes a waveguide member which supports the workpiece with a portion of the waveguide member positioned in a reactor and causes microwaves output from a high-frequency output device to propagate to the workpiece. In a process of gradually increasing an intensity of the microwaves propagating to the workpiece through the waveguide member from “0”, the intensity of the microwaves output from the high-frequency output device when step-up of a bias current of the workpiece occurs is referred to as a first intensity, and in a process of gradually increasing the intensity of the microwaves from the first intensity, the intensity of the microwaves when step-up of the bias current occurs again is referred to as a second intensity. During film formation, the microwaves having an intensity of higher than the first intensity and lower than the second intensity are output from the high-frequency output device.

Abstract: A control device for a motor-driven fuel pump adapted for an internal combustion engine is provided. The fuel pump includes a cylinder, a mover in the cylinder, and an electric actuator configured to move the mover. The control device is configured to perform energization control on the electric actuator to reciprocate the mover so that the fuel pump draws in and discharges fuel. The control device is also configured to control a discharge count and a unit discharge amount based on an operating state of the internal combustion engine. The discharge count is a number of times of discharging fuel from the fuel pump to the fuel pipe during a period between a fuel injection from the fuel injection valve and the next fuel injection, and the unit discharge amount is an amount of fuel for one fuel discharge from the fuel pump.

Abstract: In the coil spring of the present invention, a helical space defined by a space between coils has a first end region whose space is increased as it extends towards the other side in the axial direction from a first reference point where the space is zero, a reference region whose space is set at a reference value L (L>0), and a second end region whose space becomes narrow as it extends toward the other side in the axial direction and zero at a second reference point. The first end region has a first end outer part and a first end inner end. In a case where a pitch angle of the space between coils that causes the displacement of the space between coils per turn of the helical space to be L is a reference pitch angle Pa, the pitch angle in the first end outer part is set at Pa while the pitch angle in the first end inner part is set at Pb (Pb>Pa).

The first end region is configured such that the number of turns of the helical space is greater than 1 and the space between coils in a terminal position is greater than the reference value L. The helical space has a first transitional region between the terminal position of the first end region and the reference region, the first transitional region being configured so that the distance of space between coils is reduced from the terminal position of the first end region along the helical shape of the helical space toward the other side in the axial direction and becomes the reference value L.

Abstract: A control device for an fuel pump includes an electronic control unit. The fuel pump is an electric fuel pump configured to supply fuel to a fuel pipe to which a fuel injection valve disposed within a cylinder of an engine is coupled. The electronic control unit executes an inter-injection discharge control of executing fuel discharge from the fuel pump at a predetermined timing between an Nth fuel injection and an (N+1)th fuel injection from the fuel injection valve. The electronic control unit changes a discharge ratio in accordance with an operational state of the internal combustion engine during the execution of the inter-injection discharge control. The discharge ratio is a ratio of the number of times of fuel discharge from the high-pressure fuel pump to the number of times of fuel injection from the fuel injection valve.
