Abstract

When a fuel lid goes from an open state to a closed state and a pressed state and then returns to the closed state, a contact/non-contact switching mechanism switches a signal outputted from a microswitch from an ON signal to an OFF signal by performing a first operation. When the fuel lid goes from the closed state to the pressed state and then returns to the closed state, the contact/non-contact switching mechanism switches the signal outputted from the microswitch from the OFF signal to the ON signal and the OFF signal in that order by performing a second operation. Under a condition at least of the signal outputted from the microswitch switching from the OFF signal to the ON signal and the OFF signal in that order within a prescribed time, a control unit controls a lifter to rotate to another side around an axis line.

When the operation lever (21) is moved after the lock release switch (40) is operated, a shift mechanism (15) switches to forward-side shift or backward-side shift in accordance with the output of a detector (26). If the lock release switch (40) is not operated, the operation lever (21) moves but the shift mechanism (15) is not actuated because no signal permitting a shift is output.

Abstract

A ship is provided with an actuator, an operation unit, a ship control device, a time measurement unit, and a ship position detection unit for detecting the actual ship position. The ship control device has a normal operation mode in which the actuator is actuated according to an input operation, and a ship fixed point holding mode in which the actuator is actuated without the need for an input operation. During the ship fixed point holding mode, the ship control device actuates the actuator on the basis of deviation between a target ship position and an actual ship position, and the time measurement unit starts measuring time at the moment when the actual ship position deviates from a time measurement start determination area including the target ship position. When the actual ship position does not return to a ship fixed point holding mode stop determination area including the target ship position from the start of time measurement until a specified time elapses, the ship control device ceases the ship fixed point holding mode.

Abstract

The present invention effectively prevents a segment coil from being displaced in the axial direction of a core when the terminal of a segment coil leg portion is bent in the radial direction of the core. With this manufacturing method, a stator provided with a plurality of segment coils (40), both leg portions (42A, 42B) of which are inserted into each slot of a stator core and which are overlapped in the radial direction of the stator core into multiple layers (46A, 46B, 46C) and aligned in an annular shape, is manufactured. In this manufacturing method, a tool (74) having teeth (76A, 76B, 76C) is moved by a robot manipulator and thereby the teeth (76A, 76B, 76C) are inserted between the terminals of the leg portions (42) of the respective layers (46A, 46B, 46C). The tool (74) is then turned by the robot manipulator (72) to the outside in the radial direction of the stator core by setting a clamping portion for clamping the leg portions (42) by a clamp (78) as the rotation center K1 and thereby the teeth (76A, 76B, 76C) are tilted.

Abstract

The present invention effectively suppresses displacement of segment coils in the axial direction of a core when the ends of segment coil leg parts are bent. This production method produces a stator (10) that comprises a plurality of segment coils (40) that are annularly arranged in a plurality of layers (46A, 46B, 46C) that overlap in the radial direction of a stator core (14). The production method involves a tool (74) that has teeth (76A, 76B, 76C) being moved by a robot manipulator (72) and the teeth (76A, 76B, 76C) being inserted between the ends of leg parts (42) of the layers (46A, 46B, 46C). The ends that engage the teeth (76A, 76B, 76C) are thereby bent so as to be substantially crank-shaped. Before the teeth (76A, 76B, 76C) are inserted between the ends, a restraining jig (86) is inserted between bend parts (44) of the segment coils (40) of the layers (46A, 46B, 46C) and an end surface (14A) of the stator core (14) that is on one side in the axial direction.
