摘要： PROBLEM TO BE SOLVED: To provide a highly reliable AC generator for a vehicle, which can achieve high output while suppressing the occurrence of eddy voltage.
SOLUTION: The magnetic clearance δ between a rotor 5 and a stator 6 is set to 0.55-0.65 mm, using a permanent magnet 17, 1.0 (T) or over in residual magnetic flux density. Consequently, even if the rotor 5 is rotated at high speed in case that the magnitude of stationary electric load connected is small, voltage more excessive than objective regulation voltage is not generated by the magnetic flux leaked from the permanent magnet 17, so excessive voltage more than specified is never applied to electric load or a battery mounted on the vehicle.

摘要翻译：要解决的问题：提供一种用于车辆的高度可靠的交流发电机，其可以在抑制涡流电压的发生的同时实现高输出。解决方案：使用永磁体17,1.0（T）或更高的剩余磁通密度，将转子5和定子6之间的磁隙δ设定为0.55-0.65mm。因此，即使转子5在连接的静止电负载的大小小的情况下高速旋转，则从永磁体17泄漏的磁通不会产生比目标调节电压过大的电压，所以过多的电压超过规定的范围不应用于电气负载或安装在车辆上的电池。版权所有（C）2004，JPO

摘要： PROBLEM TO BE SOLVED: To provide a shape of a terminal used for connection to leading wires led from the electrical component of a vehicle alternator, which is suitable for a Tig welding method (a non-consumable electrode gas shield arc welding method) and can be welded to the terminals to be connected of the leading wires without being affected by dimensional accuracy between the terminals to be connected.
SOLUTION: A terminal having this shape is formed in a cross shape of which the extended portions are formed at a position close to the welding portion of the terminal such that they have a lager area than that of the welding portion, then it makes possible to control the penetration depth of welding because the terminal has a larger volume, then lager heat capacity than those of the welding portion, which also makes the penetration depth stable without being affected by dimensional accuracy between terminals to be connected. As an extended portion for welding is bent toward a terminal to be connected, the terminal can be easily aligned as well as a melting-amount-limitation effect can be controlled.

摘要： PROBLEM TO BE SOLVED: To improve the reliability of a vacuum pump by providing an inundation-prevention sheet at the end of a through hole formed through a casing to prevent the penetration of leakage oil from oil seals thereinto and discharge the oil to the outside as well as to prevent the inundation from the outside thereinto. SOLUTION: In the space between oil seals 9a and 9b and an oil seal 9c, a through hole 5b is formed through a casing 5 for discharging leakage lubricating oil from the oil seals 9a and 9b to the outside. A sheet 10 with its smallest- diameter portion being larger than the bore of the through hole is provided at the end of the through hole 5b with an interval therebetween. Leakage lubricating oil from the oil seals 9a and 9b is sealed off by the oil seal 9 and is then discharged through the through hole 5b to the outside. The discharge of the leakage lubricating oil prevents the tearing of a belt for transmitting engine torque caused by the deposition thereon of leakage lubricating oil lead toward a pulley 8.

摘要： PROBLEM TO BE SOLVED: To surely prevent the breakage of a vane by the reverse rotation of a vacuum pump, in a vane type vacuum pump suitably used for a vacuum booster for motor vehicle, by providing a pressure reducing means in a displacement chamber which is abnormally raised in pressure when the vacuum pump is reversely rotated. SOLUTION: When an engine is operated to rotate a rotor 3 through a rotating shaft 1, displacement chambers 11a-11c are changed in volume according to the rotation of the rotor 3, and the air sucked through an intake port 6 and lubricating oil are discharged through a discharge port 9. In this case, a pressure rising preventing groove 12 for storing or releasing the lubricating oil or air is formed on the casing 5 or plate 8 located in a space (chamber) 11a formed between the minimum clearance part between the inside surface of the casing 5 and the outside surface of the rotor 3 and the intake port 6 located in the position of about the angle of 360 deg./the number of vanes in the normal rotating direction on the basis of the minimum clearance part. According to this, pressure rising within the space 1a in the reverse rotation of the vacuum pump can be reduced to prevent the breakage of the vanes.

摘要： PURPOSE:To improve a sealing characteristic between a suction side low pressure chamber and a delivery side high pressure chamber, by providing a recess, which overlaps its starting end with a delivery port and places the other end being adjacent to the suction side low pressure chamber, in a vane sliding surface in the internal periphery of a casing and forming a surface seal between a rotor and the casing. CONSTITUTION:A casing 1 forms a recess 12 over an angle theta about the center G of the casing serving as the center in a contour larger by a fine gap l than an internal diameter of the casing 1. And the casing 1, forming said recess 12 in the direction of rotation of a rotor 2 to be started with a part of the angle theta overlapping with the position of a delivery port 5 and the recess 12 to be ended to the predetermined angle theta in the side of a suction port 4, is formed so that an end part of the recess, adjacent to a suction side low pressure chamber 6, can provide a surface seal with the peripheral surface of the rotor 2. In this way, a useless compression stroke of fluid in the fine gap l, as viewed in the past by a vane 3 after it passes through an end point P of the delivery port 5, can be eliminated because the delivery port 5 is provided in a range of the angle theta of the recess 12. As a result, the casing 1, which can suppress a leak of the fluid from a delivery side high pressure chamber 7 to the suction side low pressure chamber 6, enables pump performance to be improved.

摘要： PURPOSE:To eliminate the need of piping for supplying oil and to prevent deterioration in composition of the exhaust gas by a construction wherein a hysteresis clutch is provided between the end of rotary shaft of a rotor in the hynamo section and the end of rotary shaft of a pump rotor so as to provide the unitized structure. CONSTITUTION:The rotating force of an engine drives a pulley 1 and its driving torque rotates through a shaft 2 a primary coupling 3 of a hysteresis type electromagnetic coupling, the coupling 3 having a permanent magnet. A fan 4 is thus rotated to suck air in the interior of a charging dynamo 10 for vehicles, thereby to cool internal apparatus. The air sucked by the fan 4 further cools a secondary coupling 7 and an oilless vacuum pump 8. The oilless pump 8 is so constructed that a pump rotor 12 mounted on a rotary shaft is interposed between a mounting metal fitting 22 and a plate housing therein a gas sealing material 13. The left end of the rotary shaft is fixed to a hysteresis clutch 7 on the hysteresis material side thereof.
