A laser welding method according to this disclosure is a laser welding method for welding first and second coils (members) to each other by applying a laser beam to the first and second coils in a state where the first and second coils are brought into contact with each other. The laser welding method includes: a first step of forming a weld pool by applying a laser beam to the first coil; and a second step of continuing the application of the laser beam to the first coil until the width of a bridge formed between the first and second coils becomes wider than the width of the laser beam, the bridge being formed such that the weld pool is attached to the second coil by growing.

A vehicle loads at least one of a plurality of upper units having space to store a person or an object on an under unit including a drive mechanism that rotates wheels in the vehicle. The vehicle includes an under unit including a drive mechanism that rotates wheels and the at least one of the plurality of upper units loaded on the under unit. The under unit includes a loading unit, on which the at least one of the plurality of upper units as described above can be loaded. Each of the plurality of upper units includes a joint that joins to a different upper unit that is adjacently loaded.

Vehicle, upper unit, and control device

A conveyer equipped with rotating discs rotatable around axes thereof relative to a mounting base. Each of the rotating discs has grooves in which rectangular wires are receivable. When an upstream and a downstream one of the rotating disc are arranged in a given angular relation to each other, one of the grooves of the upstream rotating disc is aligned with that of the downstream rotating disc to pass the rectangular wire from the upstream rotating disc to the downstream rotating disc. Upon such passing of the rectangular wire, the grooves of the upstream and downstream rotating discs hold or clamp all side surfaces of the rectangular wire, thereby ensuring the stability in retaining the rectangular wire when passed from one to another of the rotating discs, which enables the conveyer to carry the rectangular wires at high speeds.

Conveyer

The present disclosure makes it possible to freely exchange interior of a vehicle. An interior unit according to the present disclosure is provided with: a frame portion attachable to and detachable from a vehicle; and interior parts installed on the frame portion. The frame portion is foldable, or extendable and contractible.

Interior unit, vehicle and control method

A manufacturing method of a stator according to the disclosure includes a clamping process of clamping, among coil ends of segment coils assembled into a stator core, a pair of coil ends adjacent to each other in a circumferential direction, by a clamp jig that presses the pair of coil ends in the circumferential direction, and a welding process of welding the coil ends exposed through an opening portion provided in the clamp jig. The clamp jig includes a pressuring structure that increases a pressing force in a direction away from weld faces of the coil ends welded in the welding process, the pressuring structure being provided on at least one of sideward pressing faces that come into contact with side faces of the coil ends that are provided orthogonal to the weld faces.

A vehicle comprises an under unit which is equipped with a driving mechanism configured to rotate wheels of the vehicle, and an upper unit which is mounted on the under unit. The upper unit comprises an extension/contraction mechanism which is configured to extend or contract the upper unit according to a size of the under unit.

Vehicle, upper unit and non-transitory storage medium

The present disclosure provides a technique that enables customization of a vehicle. In an information processing apparatus, a controller presents vehicle units extracted from among a plurality of types of under units each of which is provided with a driving mechanism configured to cause wheels to rotate and a plurality of types of upper units to be loaded on any of the under units to a user, the vehicle units being combinable as a vehicle. Furthermore, the controller executes: accepting selection by a user from among the presented vehicle units; and calculating a fee in the case of providing the selected vehicle units.

Information processing apparatus, information processing system and information processing method

An arm of a coil segment having an approximate U shape is placed in a slot of a stator core, and a portion protruding from the slot is bent in a circumferential direction. An arm is bent in a direction of an arrow A, and another arm positioned at an inner side in the radial direction in relation to this arm is bent in a direction of an arrow B. The arm positioned at the outer side has at least a part of a bending inner side surface of a bent portion hardened by pressurization.
