Patent JP-2002218687-A (JP)
Title: Alternator for vehicle
Inventor: ASAO YOSHITO
IPC: H02K9/06
Filed: 2001-01-16
Abstract: PROBLEM TO BE SOLVED: To obtain an alternator for a vehicle capable of suppressing temperature rise. SOLUTION: Since a ratio (bt/ht) of a width bt and a length ht in a radial direction of the teeth 42 of a stator iron core 41 is made 0.15<bt/ht<0.4, a narrow ventilation path 100 is formed. Then, since cooling air by a cooling fan vents through the narrow ventilation path 100, the speed of the cooling air is increased, and heat generated by a stator coil 16 is efficiently radiated into the cooling air. As a result, the temperature rise of the stator 40 is suppressed. As the temperature rise of the stator is suppressed, the output is also improved. Further, even under the worst operating condition, heat deterioration caused by softening of vanish is suppressed, and a damage to a insulating coat caused by the friction between the wire of the stator coil 16 and the stator iron core 41 is also suppressed. Hence, the electric insulation quality is enhanced.

Title: Sheet conveying equipment, sheet treating device, and image forming device
Inventor: AOKI KAZUHIRO
IPC: B65H5/16
Filed: 2001-01-17
Abstract: PROBLEM TO BE SOLVED: To provide a sheet conveying equipment capable of selecting a motor with less power by reducing a load on the motor. SOLUTION: A push-out claw 13 is installed on the outer periphery of a transfer belt for transferring a sheet. The push-out claw 13 abuts on the rear end part of the sheet having an end part restricted by a stopper 21, pushes out for conveying the sheet according to the rotation of the transfer belt. The rotating speed of the motor for driving a first pulley 10 is decelerated from a position P0 immediately before a position P1 where the push-out claw 13 positioned at a home position is moved abuts on the sheet. Since a decelerating torque is produced in addition to the output torque of the motor, a load required for the sheet conveyance can be reduced.
