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.

The invention relates to a process for preparing aromatic sulfonylimides, to the sulfonylimides obtained, and to the use thereof as salt of an electrolyte. The sulfonylimides correspond to the formula [R—SO₂—N—SO₂R′]_rM (I). R′ is an ArZL- group. R′ is a perfluoroalkyl group or an ArZL- group. Z is an S, SO or SO₂ group. L is a —(CF₂)_n—CFR^f— group. n is 0 or 1; R^f represents F or a C₁ to C₈ perfluoroalkyl group; Ar is an aromatic group. M represents H, an alkali metal cation, an alkaline earth metal cation, a trivalent or tetravalent metal cation, or an organic cation. The process consists in preparing a compound RSO2N(R′)SO2R′ from RSO₂F, and in replacing the group R′ by nucleophilic substitution reaction so as to obtain the compound (I), R′ being a benzyl or trimethylsilyl group.

A crimping terminal fitting has a wire barrel (21) to be crimped and connected to core strands (31) of a wire (30). The wire barrel (21) has a base plate (23) continuously extending from a ground terminal (11) in a longitudinal direction. Two core crimping pieces (25) extend from the opposite sides of the base plate (23). A thinned portion (27) is formed at least at a leading end of each core crimping piece (25) and is thinner than the base plate (23).

An SiO₂ layer (3), a Ti layer (4), a Pt layer (5), a PLZT layer (6) and an IrO₂ layer (7) are formed sequentially on an Si substrate (2). The IrO₂ layer (7) functioning as a top electrode has a thickness of about 100 nm. Since the IrO₂ layer (7) has conductivity lower than that of Pt or the like conventionally used as a top electrode and a skin depth deeper than that of Pt or the like, sufficient sensitivity can be attained by a thickness of about 100 nm.

A compact valve using a shape memory alloy comprises: a moving valve body that contacts an inner periphery of a guide pipe having an built-in orifice, is freely movable and has a sealing portion to seal the orifice; a biasing coil provided between the orifice and the moving valve body; and a wire formed of a shape memory alloy and held between a stationary electrode of the guide pipe and a moving electrode of the moving valve body. The orifice is sealed by moving the moving valve body due to transformation of the shape memory alloy by heating the wire. The moving valve body is enabled to be elastically deformable by providing a coil spring to reduce a stress, so that an overload to the moving valve body due to contraction of the wire is absorbed by elastic deformation of the moving valve body. Thereby, the overload to the shape memory alloy is reduced to prevent deterioration of repeatability of memorized shape, to increase durability and reliability of the valve.

It is an object of the invention to provide a method of producing a spark plug in which, in order to reduce the size of the spark plug, the diameter of a center electrode can be reduced while maintaining the heat dissipation property of the center electrode, and also such a spark plug. A columnar member 220 in which an outer skin member 21 made of a high refractory Ni alloy, and a core member 23 made of a copper alloy having a high thermal conductivity are clad, and which is columnarly extended can be configured by extrusion molding into a state where the thickness of the outer skin member 21 is substantially uniform (extrusion molding step). A flange portion 305 and a tip end portion 301 are formed in the columnar member 220 to obtain an electrode intermediate member 320 (tip end portion/flange portion forming step). In a middle trunk portion 303 of the electrode intermediate member 320, the thickness of the outer skin member 21 is maintained. The surface of the middle trunk portion 303 is cut or polished to reduce the thickness (middle trunk portion processing step), whereby the diameter of a center electrode 20 can be reduced while maintaining the outer diameter of the core member 23.
