Provided is a technique of ensuring mechanical strength in a terminal-provided wire and lowering contact resistance between the wire and the crimp terminal, without greatly varying a crimp height of a crimp terminal onto the wire in an axial direction. A crimp terminal according to the invention includes a conductor barrel which is crimped to a conductor of a wire. The conductor barrel has an inner surface which closely contacts the conductor by bending. The inner surface has such a shape a surface thereof which closely contacts a tip end side part of the conductor inwardly projects beyond a surface thereof which closely contacts a base side part of the conductor, thus performing a higher compression of the tip end side part of the conductor than that of the base side part thereof by the bending.

The present invention is aimed at bonding a lower chip and an upper chip through bumps in a highly reliable manner, while ensuring a sufficient area for an external connection terminal region, by offsetting the upper chip to the lower chip. The substrate 2 has bumps 1 arranged on one surface thereof, and has a first chip 3 mounted on the other surface thereof. A second chip 4 is bonded to the first chip 3 through bumps 5, 6 while offsetting the second chip 4 to the first chip 3 in parallel. In the bonded state of the first chip 3 and the second chip 4, a part of the first chip 3 and a part of the second chip 4 are overlapped without aligning the centers of the both. The center of gravity of the second chip 4 falls inside a region surrounded by the outermost bumps between the first chip 3 and the second chip 4.

This present application discloses an electronic cigarette, comprising an atomizer and a battery rod, a connecting structure, and an elastic structure; the connecting structure includes a first connecting member and a second connecting member; the first connecting member is provided with at least one engaging portion, the second connecting member defines a butt-jointed groove, a wall of the butt-jointed groove extends away from a rabbet of the butt-jointed groove to form at least one channel structure, the channel includes an inserting guide channel, a taking-out guide channel, and a bending channel, and the bending channel forms a buckled portion; the elastic structure is configured for supplying elasticity towards the rabbet of the butt-jointed groove to the first connecting member, so that the engaging portion is engaged with the buckled portion. The non-threaded connecting structure is simple and is convenient to operate, which improves users' experience.

A fuel cell vehicle includes a vehicle body having a floor frame; a fuel cell that generates electricity by the electrochemical reaction of hydrogen and oxygen; and a subframe on which the fuel cell is mounted, being attached to the lower side of the floor frame and has a pair of side frames that extend in the fore-aft direction of the vehicle body, wherein the bottom end of the fuel cell disposed at a position between the upper end and the lower end of the subframe.

The invention is a fan for an alternator adapted to be coupled in rotation to the alternator rotor, and being of the type comprising a wheel part and a plurality of fan blades (47, 48) extending from the latter, the fan being moulded in a plastics material on an insert (50) which is preferably of metal and which constitutes the wheel part of the fan and is arranged to provide fastening of the fan on the rotor, being configured so as to constitute a means for increasing the mechanical strenght of the fan; the insert (50, 65) includes at least a portion of a blade (48, 69) of the fan. The invention is useful in the manufacture of a high power cooling fan for a motor vehicle alternator.

Provided is a crimp terminal designed to be crimped onto an end portion of an electric wire to form a terminal-equipped electric wire, achieving both of ensuring mechanical strength of the terminal-equipped electric wire and reducing a contact resistance between the electric wire and the crimp terminal. The crimp terminal comprises an electric contact section and an electric-wire crimp section to be crimped onto a conductor in the end portion of the electric wire, the crimp terminal being formed of a metal plate which has a copper-containing plate body and a tin-plating layer covering a surface of the plate body. In the crimp terminal, the tin-plating layer has a smaller thickness in a crimp surface region where the electric-wire crimp section is to make contact with the end portion of the electric wire is less than that in an electrical contact surface region where the electric contact section is to make contact with a counterpart terminal.

Two new High Slot Utilization (HSU) Systems for electric machines enable the use of form wound coils that have the highest fill factor and the best use of magnetic materials. The epoxy / resin / curing treatment ensures the mechanical strength of the assembly of teeth, core, and coils. In addition, the first HSU system allows the coil layers to be moved inside the slots for the assembly purpose. The second system uses the slided-in teeth instead of the plugged-in teeth. The power density of the electric machine that uses either system can reach its highest limit.
