    摘要： A high-pressure fuel pump control device capable of reducing current consumption, increasing pump durability, and promoting a rise of fuel pressure from startup. The high-pressure fuel pump control device comprises a fuel injector valve for directly injecting fuel in a common rail into a combustion chamber and a high-pressure fuel pump for feeding the fuel under pressure to the common rail. The high-pressure fuel pump comprises a pressurization chamber, a plunger for pressurizing the fuel in the pressurization chamber, a fuel passage valve disposed in the pressurization chamber, and an actuator for actuating the fuel passage valve. The control device includes a control unit for executing output control of a drive signal for the actuator to vary a discharge rate of the high-pressure fuel pump. The control unit starts outputting of the actuator drive signal during a period from operation start to a point in time at which the actuator drive signal becomes able to issue in a predetermined crank angle phase, and sets timing of stopping the outputting of the actuator drive signal to a point in time at which the fuel pressure in the common rail has boosted over a predetermined value per unit time.

    摘要： The invention provides a control apparatus of a cylinder injection of fuel type internal combustion engine executing a dilute combustion, which can satisfy a requirement of rapidly changing an engine torque while restricting a deterioration of a driving property and an exhaust gas as much as possible. In a control apparatus of a multicylinder engine executing a dilute combustion, in the case that a requirement of reducing and changing an engine torque of the internal combustion engine is applied, the control apparatus executes a fuel cut of a predetermined number of cylinders, and controls so that a torque of operating cylinders except the cylinders executing the fuel cut becomes the required engine torque.

    摘要： By changing coefficients of second-order and first-order calculation terms relating to respective hues, and first-order calculation terms in the form of comparison-result data relating to respective inter-hue areas, only the target hue or inter-hue area among the six hues of red, blue, green, yellow, cyan, and magenta, and the six inter-hue areas can be varied, without affecting other hues and inter-hue areas. Thus, the six hues and six inter-hue areas can be corrected independently, and the large-capacity memory is not required.

    摘要： A rotor (10) includes a plurality of permanent magnets (14) disposed around a shaft (12) at generally equal intervals, and a plurality of laminated core members (16) disposed between the permanent magnets (14) so as to form magnetic poles. The laminated core members (16) are formed by stacking a plurality of core-laminations (26) made of magnetic materials and an integral core-lamination, and joining them to each other. The integral core-lamination includes a plurality of core-lamination sections each having a shape the same as that of the core-lamination (26), and connecting portions (46) for connecting adjacent core-lamination sections with each other. When the large number of core-laminations (26) and the integral core-lamination are integrally joined by a press-fitting process, the laminated core members (16) are connected with each other in such a relative arrangement of a finished assembly that a space for locating the permanent magnet (14) is defined between the adjacent laminated core members (16), and thus an integral laminated rotor core (48) is formed.
