According to the invention, there can be provided a non-aqueous electrolyte secondary cell whose capacity is hardly decreased even stored at high temperatures in a charged state.The non-aqueous electrolyte secondary cell uses an insulation adhesive tape composed of a base material and a glue material. And in an absorbance spectra of the glue material measured using an infrared spectrophotometer so that the maximum peak intensity is 5 to 20% in transmittance, when peak intensities for C—H stretching vibration of 3040 to 2835 cm−1 and C═O stretching vibration of 1870 to 1560 cm−1 are respectively defined as I(C—H) and I(C═O), a peak intensity ratio represented by I(C═O)/I(C—H) is 0.01 or less.

The present invention provides a stator coiled in a spiral, capable of mechanically inserting a wound coil in the slot of a stator core. In a stator in which coils are overlapped in a spiral when viewed from the end surface of the stator core after each of one sides of a plurality of coils wound in advance is inserted in the slot of the stator core and each of the other sides of the plurality of coils is inserted in a different slot, by repeating the inserting operation twice or more, the loop of the coils overlapped in a spiral are piled in two layers or more in the radius direction of the stator core and the total coil sectional area inserted in the slots of the stator core is larger than a prescribed value based on the inside radius of the stator core.

A magnetostrictive device for a torque sensor which has a high sensor sensitivity whether the excitation frequency is in a high frequency range or in a low frequency range and can withstand excess load torques well, and also a method of easily manufacturing the device. In manufacturing the magnetostrictive device 1 for a torque sensor, which has a magnetic anisotropic portion 15 formed on the surface of a shaft body 10 thereof, the method of forming the magnetic anisotropic portion 15 comprises the steps of: forming spiral grooves in the surface of the shaft body 10 to form a plurality of troughs 16 and ridges 17 alternately; and directly applying a compressive stress only to the ridges 17 to cause deformations accompanied by plastic flow and to provide an almost planar plateau portion 171 at a crest portion of each of the ridges 17.

In a liquid fuel combustion apparatus, the upper end of a wick is ready to be ignited when it projects upward from a pan portion, and is extinguished when it is withdrawn downward from the pan portion. The wick moves up and down as a first operating lever swings around an operating shaft. If the first operating lever is lowered, a retaining lever is raised by a bent strip. When the wick is in a position for high-temperature combustion, a retaining portion of the retaining lever engages a receiving portion of an interlocking plate. When the first operating lever is lowered, its engaging pin engages an engaging slit of an adjusting lever. If a knob of a thermal power control plate is moved up and down along a slot, the adjusting lever swings around a support pin, and the first operating lever swings slightly through the engaging pin and the engaging slit. Thus, the wick is moved up and down in a combustion region for adjustment of thermal power. If an extinction lever is operated or if a movement-sensitive pendulum is activated, the retaining portion is disengaged from the receiving portion to cause the operating shaft to rock at a stroke in an extinction direction. Thus, the wick is extinguished in an instant.
