IPC: H02K23/04
Filed: 1986-09-25
Abstract: PURPOSE:To reduce cogging torque, by using the armature of a salient pole type, and by providing a field system section with auxiliary grooves. CONSTITUTION:A rotary electric machine is composed of a back yoke 1, the field system section 2 of a permanent magnet, the armature core 4 of a salient pole type, and a threephase armature winding 5 wound up on the core. In this case, a section confronted with the armature core 4 in the field system section 2 is provided with auxiliary grooves 7a-7b in the direction of the axis of a rotational center 6. Then, magnetic flux generated from the field system section 2, bypassing field boundary sections 3a-3b and the auxiliary grooves 7a-7b, most of which are high magnetic reluctance, is absorbed by the armature core 4, and the state of the magnetic nonuniformity of the field system section is changed. Accordingly, harmonic component in relation to cogging torque is reduced, and the cogging torque can be reduced.

Abstract: PURPOSE:To prevent contamination and overflow when automatically feeding fuel oil based on the result of oil type identification, by selectively driving a first or second pump according to the output of an oil type sensor. CONSTITUTION:When an oil feed nozzle 9 is detached from a nozzle holder, an air pump 23 starts a sucking operation, so that a gas flows into an oil type sensor 19 from a suction pipe 28. When the nozzle 9 is inserted into the fuel tank of a vehicle in this condition and an oil feed lever 24 is pulled up, a controller 16 identifies an oil type based on a change in the level of a signal from the oil type sensor 19. When identifying it as gasoline, the controller 16 drives a first pump motor 3 to feed gasoline to the fuel tank via an oil feed hose 7 and a nonreturn valve 11. When the nozzle 9 is returned to the nozzle holder after the feed of the specified amount of the oil is finished and the main valve of the nozzle 9 is closed by the oil feed lever 24, the motor 3 is turned off. When the controller identifies the oil type as light oil, on the other hand, it operates a second pump motor 4 to feed light oil.

Abstract: PURPOSE:To attain the structure of excellent heat sink by applying padding to a center at the inner face of an outer case arranged with an optical repeater unit with a metal having a good thermal conductivity. CONSTITUTION:The inner face of an outer enclosure 2 is subjected to padding and the padding part 2a is incorporated with the outer enclosure 2 by applying centrifugal casting, hot fit or pressing for a metal with a good heat conductivity such as copper. The size of padding is designed so that the repeater unit 1 and the outer enclosure 2 are not allowed to contacted with each other even when a buffer 3 is deformed by a shock.
