"The present invention relates to servo-actuators for providing mechanical output such as rotation of a shaft in response to energization（動作）of an electric drive motor. The invention relates particularly to rotary actuators driven by a low voltage motor such as a small relatively high RPM（高回転型）motor of sub-fractional horsepower operating from a vehicle on-board power supply, typically in the range 12-24 volts. Electrically operated servo-actuators have been found desired for various on-board vehicle applications."

"[0001] The present invention relates to a spur gear transmission with at least two toothed spur gears, in particular according to the preamble of the independent claims. 

[0002] Spur gear transmissions of the type in question are known, for example, from WO 2012/028231 A1. Such spur gear transmissions are designed, for example, as high-speed（高回転型）transmissions, such as turbo transmissions."

"In particular, the engine E of the motorcycle runs at a higher engine speed（高回転型である）than that of a four-wheeled vehicle (automobile). For this reason, the temperature of the catalyst 38 tends to be elevated at a high change rate in the motorcycle. Therefore, the configuration of the present embodiment is effectively used in the motorcycle."

"An engine starting apparatus is provided which is equipped with a starter, an inrush current reducer, and a starter mode switch. The inrush current reducer works to reduce an inrush current flowing through an electric motor installed in the starter when the electric motor is energized. The starter mode switch works to change a starter characteristic that is an output characteristic of the starter continuously or selectively at least between a low-torque/high-speed mode（高回転型）and a high-torque/low-speed mode. The starter mode switch places the starter in the high-torque/low-speed mode at least at a time when a piston of the engine is passing a top dead center, and the engine friction has been just maximized for the first time after the starter is actuated to crank the engine. This shortens a period of time required to start up the engine without sacrificing beneficial effects offered by the inrush current reducer."

"[0099] The motor 15 of the present embodiment is a high rotation type（高回転型）motor. One reason for adopting the high rotation type motor as the motor 15 is to enable feedback control (i.e., constant rotation control) so that the motor 15 may have a constant rotational speed by pulse-width modulation (PWM) driving, and further to expand, as wide as possible, the load region in which the rotational speed of the motor 15 can be maintained constant. In the present embodiment, degradation in the rotational speed due to load in the practical region is inhibited by using a motor that can be rotated at a high rotational speed relative to another motor with respect to the same current value."

"[0017] As for the motor, a low torque.high rpm（高回転型）brushless-type motor is used for this power steering system, and used in a range where the number of revolutions of the motor is more than 3000 rpm (3000 revolutions per minute). As shown in FIG. 4, when the number of revolutions of the motor is greater than or equal to 3000 rpm, the motor can work in the high efficiency range (its efficiency is greater than or equal to 60 percent (%))."
