Abstract

A ship propulsion device controller controls a plurality of ship propulsion devices disposed on a rear portion of a hull of a ship. The ship includes an operation unit configured to operate the ship propulsion devices. The operation unit is able to be positioned at a first position where the ship propulsion devices do not generate propulsion forces for the ship and a second position where the ship propulsion devices generate propulsion forces for moving the ship in a right direction, a right-forward direction, or a right-backward direction or a third position where the ship propulsion devices generate a propulsion force for moving the ship in a left direction, a left-forward direction, or a left-backward direction. When the operation unit is moved from the first position to the second position and maintained at the second position, the ship propulsion devices generate a clockwise rotating moment in the ship during a first period from a first timing when the operation unit is moved to the second position to a second timing and do not to generate the clockwise rotating moment in the ship during a second period after the second timing.

Abstract

A rotor includes a rotor core configured by laminated steel plates and a magnet insertion hole extending along an axial direction of the rotor core, with a resin interposed between a permanent magnet placed in the magnet insertion hole and an inner wall face of the magnet insertion hole. In a manufacturing method for this rotor, in a first process, the permanent magnet and the resin are integrated together to manufacture a resin-coated permanent magnet that is capable of being press-fitted into the magnet insertion hole. Next, in a second process, the resin-coated permanent magnet is press-fitted into the magnet insertion hole. Next, in a third process, the post-second-process rotor core is heated to a temperature that is at least the temperature at which the resin softens. Accordingly, the softened resin is pressed in a rotor radial direction against the inner wall face of the magnet insertion hole and deformed so as to be fitted closely against undulations of the inner wall face of the magnet insertion hole. Next, in a fourth process, the post-third process rotor core is cooled.

Abstract

A control device for an outboard motor controls a plurality of outboard motors included in a ship. Each outboard motor includes a propulsion unit and a steering actuator. The ship includes an operation unit that operates the steering actuator and the propulsion unit. The operation unit can be positioned at a first position at which the outboard motors do not generate a propulsion force for the ship, a second position at which the outboard motors generate a propulsion force for moving the ship in a leftward-rightward direction, and a third position at which the outboard motors generate a propulsion force for moving the ship in an oblique direction that forms an acute angle with the leftward-rightward direction. A forward-backward direction component of a propulsion force in the oblique direction which is generated by the outboard motors in a case in which the operation unit is moved from the first position to the third position via the second position is larger than that in a case in which the operation unit is moved directly from the first position to the third position, or a leftward-rightward direction component of a propulsion force in the oblique direction which is generated by the outboard motors in the former case is smaller than that in the latter case.

Each of the outboard motors includes a propulsion unit and a steering actuator. A boat includes an operation unit configured to operate the steering actuator and the propulsion unit. The operation unit is able to be positioned at a first position where the outboard motors do not generate a propulsion force of the boat and a second position where the outboard motors generate a propulsion force for moving the boat in a left-right direction. When the operation unit is moved from the first position to the second position and maintained at the second position, the outboard motors generate a first propulsion force during a first period from a first timing when the operation unit is moved to the second position to a second timing and subsequently generate a second propulsion force greater than the first propulsion force during a second period after the second timing.

Abstract

A load beam includes a pair of flange bending parts including first bending parts, and a second bending part extending in a width direction. A first cross-section part extends in the width direction of the load beam passing through welding parts. The first cross-section part is warped up toward the flange parts. A second cross-section part extends in the width direction passing through a different position from that of the welding parts. The second cross-section part has a lesser height difference as compared to the first cross-section part. A die is used when bending the second bending part. The die includes a first relief part including a first inclined surface and a second relief part including a second inclined surface in both sides of the supporting surface.

Abstract

A coiling machine includes a laser heating machine configured to irradiate a wire formed into a helical shape with laser light to thereby heat a part of the wire, and cutting components configured to cut a portion of the wire after the irradiation of the laser light is stopped, a temperature of the portion being higher than before irradiated with the laser light.

Abstract

A suspension coil spring device may include a compression coil spring (10) that has a coating film, a rubber vibration isolator, and an adhesive layer that joins the compression coil spring and the rubber vibration isolator to each other. The adhesive layer is a cured product of a hot melt adhesive that melts at 80° C. to 100° C. A softening point of the hot melt adhesive is lower than a heat-resistant temperature of the coating film. The softening point of the hot melt adhesive is lower than a heat-resistant temperature of the rubber vibration isolator.

Abstract

A joined body includes: a main body section including a wall section forming a passage along which a medium for accelerating heat exchange flows; and a cover configured to cover a surface of the main body section, the cover including: a covering section provided on a side facing the main body section and configured to cover the surface; a groove section provided on the side facing the main body section and configured to accommodate an end portion of the wall section; and a stirred joint section provided on a side opposite to a side where the covering section and the groove section are provided, the stirred joint section being at least partly frictionally stirred by a depth reaching a bottom of the groove section from a surface on a side opposite to the side facing the main body section and bonded to the end portion of the wall section.

Abstract

A coiling machine includes feed rollers for moving a wire, a wire guide, a first forming roller, a second forming roller, a pitch tool, a cutting mechanism, and a support mechanism for supporting the wire. The cutting mechanism includes a cutting rotor. The wire coming out of the wire guide is formed into a helical shape by the first forming roller, the second forming roller and the pitch tool. After one coil spring of a predetermined length is formed, the wire is cut by moving the cutting rotor in the radial direction of the wire. The cutting rotor cuts the wire supported by the support mechanism in the radial direction of the wire between the second forming roller and the pitch tool.
