摘要： PROBLEM TO BE SOLVED: To improve durability of a position (rotating angle) detecting unit in an electric actuator with a position (rotating angle) detector. SOLUTION: A pattern plate 153 is provided in the side of an output shaft 127. Consequently, since a sliding distance of the first and second brushes 155, 156 and the first and second pulse patterns 151, 152 can be shortened, a relative sliding velocity of the first and second brushes 155, 156 for the first and second pulse patterns can be reduced. Accordingly, wear of the first and second brushes 155, 156 and first and second pulse patterns 151, 152 can be controlled. As a result, durability of actuator 100 can be improved.

摘要： PROBLEM TO BE SOLVED: To increase output torque of an electric actuator without increasing vibration or noise. SOLUTION: A direct current motor 110 is adopted, and a rotating position is detected by a two phases pulse output system. Thereby, the inexpensive electric actuator 100 can be achieved, and the output torque of the electric actuator 100 can be increased without increasing vibration and noise. Further, a position returned from a position on which a link lever abuts on a stopper for several pulses is made to be an operation reference. Thus, deterioration of durability caused by creep can be prevented. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To connect each of actuators to a control unit by a network using data communication. SOLUTION: Each of connectors 23 contains a motor drive circuit and communication circuit. Since each actuator 21 side does not contain the motor drive circuit and communication circuit, a conventional actuator that does not contain a motor drive circuit and communication circuit can be employed to all of the actuators 21 irrespective of control or non control of the actuators 21 by the data communication. As a result, an increase in the number of kinds of the actuators including maintenance parts to cause an increase in the amount of inventories of the actuators is suppressed, and each of the actuators can be connected to the control unit by the network using the data communication.

摘要： PROBLEM TO BE SOLVED: To reduce the cost for manufacturing an air conditioner for a vehicle by applying a structure capable of dispensing with a relay for controlling the driving current of a blower. SOLUTION: Negative electrode sides (ground side) of an electronic controller 11 for air conditioning, a driving circuit 12 and a motor electronic controller 13 are made in common with each other in a joint electronic controller 10 to be earthed to a vehicle body through one earth wire 10a connected to the joint electronic controller 10. Whereby the negative electrode sides of the driving circuit 12 and the motor electronic controller 13 are earthed on the vehicle body at the same place, and the potentials of the earthing points Mp and Ep of the driving circuit 12 and the motor electronic controller 13 are allowed to be agreed with each other, which dispenses with the relay mounted on the positive electrode side of the blower 3, and an electric wiring (wire harness) for driving the relay, and reduces the cost for manufacturing the air conditioner for the vehicle.

摘要： PROBLEM TO BE SOLVED: To ensure an excellent state of engagement of a pinion gear and a reduction gear by noticing that pitch precision between the rotating shaft of a stepping motor and the gear shaft of the reduction gear, and positioning a bracket of the stepping motor and a gear case on an extention line of the center line of the gear shaft. SOLUTION: In a motor actuator 1 constituted by externally fixing a stepping motor 4 to the external surface of a ceiling wall of a gear case 2 including a reduction gear 11 engaging with a pinion gear 10 fixed to a rotating shaft 9 of a stepping motor 4, an engaging hole 64 is formed on an extension line of the center line of a gear shaft 6 of a bracket 5 of the stepping motor 4, and one end portion of the gear shaft 6 protruded on the motor side from the external surface of the ceiling wall of the gear case 2 is engaged with the hole 64. Thereby the pitch between the rotating shaft 9 of the stepping motor 4 and the gear shaft 6 of the reduction gear 11 is directly determined.

摘要： PROBLEM TO BE SOLVED: To prevent the offset of a corresponding relationship between the detected rotating angle of a potentiometer and the oscillating angle of a deflecting fin even when the deflecting fin is oscillated with manual operation. SOLUTION: A potentiometer 119 is actuated in mechanical association with a first arm 116 via a shaft 120 penetrating an output shaft 114. In this way, even when a deflecting fin is moved with manual operation, a swing louver can be miniaturized while preventing the offset of a corresponding relationship between the detected rotating angle of the potentiometer 119 and the oscillating angle of the deflecting fin.

摘要： PROBLEM TO BE SOLVED: To make simplifying an air conditioned wind shutting mechanism consistent with an excellent wind direction automatically changing function. SOLUTION: The unit connects a clutch mechanism 10 arranged between wind orientation plates 5 and a driving mechanism on the side between the driving mechanism and the wind orientation plate 5 normally. When the external force of predetermined value F1 or more is applied to the wind direction plates 5, it disconnects the clutch mechanism. The spring force F2 of a movable stopper mechanism 7 regulating the swinging position of the wind orientation plates 5 is set larger than the predetermined value F1 . When the external force applied to the movable stopper mechanism 7 is smaller than the spring force F2 , the wind orientation plates 5 are set to a first swinging position that is a normal swinging range, and, when the external force applied to the movable stopper mechanism 7 is larger than the spring force F2 , the movable stopper mechanism 7 is displaced enabling the wind orientation plates 5 to swing to a second swinging position within the swinging range when the air conditioned wind is shut off.

摘要： PROBLEM TO BE SOLVED: To improve the accuracy of detected angle of rotation while ensuring sufficient durability so as to prevent the false detection due to the wear of a contact point and avoiding enlarging a device for detecting angle of rotation. SOLUTION: Pulse signals having different phases of A-phase and B-phase are generated by using a first and second pulse patterns 141, 142 disposed on a first region I, and pulse signals having different phases of C-phase and D-phase are generated by using a third and fourth pulse patterns 143, 144 disposed on a second region II. The two regions I, II are formed by dividing a pattern plate 140 into two parts in the circumferential direction. Consequently, four kinds of pulse signals having different phases can be generated without narrowing the circumferential angle of a conductive section and the circumferential angle of a nonconductive section. Accordingly, the accuracy of detected angle of rotation is improved while ensuring sufficient durability so as to prevent the false detection due to the wear of first to fourth brushes 146-149 and avoiding enlarging the device for detecting angle of rotation.
