Abstract: A package has a seal portion that includes steam passage portions for externally releasing steam from inside the tray. The steam passage portion has an inner edge in which the portions configuring one side and the other side relative to the tip are curved and extended nearing each other toward the tip. The steam passage portion has an outer edge in a curved shape with a pointed tip, the shape being similar to that of the inner edge. The steam passage portion has a merging portion located between the tip of the outer edge and the tip of the inner edge, and a non-merging portion located between the merging portion and a common portion. The non-merging portion has a width narrowed from the common portion toward the merging portion.

Abstract: An electronic power steering apparatus for a vehicle having a steering mechanism to generate a steering assisting force includes: a steering angle sensor; a steering torque sensor; a target steering torque setting unit for setting a target steering torque based on the detected steering angle; a torque deviation computing unit for computing a torque deviation between the target steering torque and the detected steering torque; a first target current value computing unit for computing a first target current value for generating a steering assisting force by the motor based on the computed torque deviation; and a vehicle speed sensitivity adjusting unit that adjusts the first target current value, at least corresponding to a detected vehicle speed, and outputs the adjusted first current value as a second target current value. The motor control unit controls the motor to generate the steering assisting force based on the second target current value.

Abstract: Provided is an electric power steering system that prevents the oscillation of the steering wheel at each steering stroke end. If the steering stroke end flag Fse is 1 or if the determination result is Yes in step S8, the EPS-ECU (21) determines if the right steering flag (Fdrc) is 1 in step S10. If the determination result is Yes, it is then determined if the steering torque difference base value (Dtsb) is positive in step S11. If the determination result of step S11 is Yes, the EPS-ECU (21) uses the steering torque difference base value (Dtsb) as the steering torque difference (Dts) in step S12. If the determination result is No, the steering torque difference (Dts) is given by a value 0 in step S13, and the control process is concluded.

Abstract: Electric power steering system comprises an electric motor (9) for producing a steering assist force reducing a steering effort of a vehicle operator and a control unit (21) determining a control value for the electric motor, the control unit being configured to determine the control value by selecting a map representing a relationship between a vehicle state variable and a control value for each of a plurality of control modes. When switching control modes, the control unit gradually changes the control value from that obtained from a map corresponding to a preceding control mode to that of a following control mode. A different time period of gradual transition from the preceding control mode to the following control mode is selected depending on those control modes.

Abstract: A motor driving method for a steering apparatus for applying an auxiliary steering force to a steering system with two motors. When the two motors are driven, a first one of the two motors is operated first. Thereafter, the other, second motor is driven, whereby smooth steering is effected.

Abstract: An electric power steering apparatus (10) includes a steering wheel (21), a steering shaft (22), a rack-and-pinion mechanism (25), and a rack shaft (26) connected to the steering wheel through the steering shaft and the rack-and-pinion mechanism. The rack shaft is connected to vehicle wheels (29, 29). The electric power steering apparatus further includes a first electric motor (41) for producing a motive power to be applied to the steering shaft, and a second electric motor (51) for producing a motive power to be applied to the rack shaft.

Abstract: Steering apparatus for transmitting a driving force of a motor through a gear mechanism to a rack shaft of a steering system and applying the driving force to steering road wheels in a steering direction. The apparatus has first and second motors. In the transmission of driving forces from output shafts of the first and second motors to the rack shaft, the phases of the two motors are essentially staggered by 180 degree.
