Abstract: An electric motor capable of ensuring insulation of proximal portions of coil edges of a stator projecting from end of a stator core, and a method of insulating the proximal portions of the coil edges of the stator. The insulation sheet has a folding portion for folding one or more coils of the same phase and two insertion portions extending from the folding portion so that distal ends are positioned away from a centerline of the folding portion. One or more coils of the same phase are folded by the folding portion and the two inserting portions are inserted into the slot or slots from which the one or more coils project. The inserting portions are drawn from inside of the stator core so that the folding portion spreads to fold the proximal portions of the coils. The inserting portions are securely held between the wall of the slots and the coils to prevent the insulation sheet from displacement, inclination and slip off to securely insulate the coils of different phases.

Abstract: In a stick-type ignition coil device for engines, a primary spool is disposed outside a secondary coil. The primary spool is made of PBT (polybuthylene telephthalate) having a low melting viscosity and a high flowability as a resin base material. The resin base material is admixed with an olefin rubber in 5 wt. %, glass fibers in 12.5 wt. % and silica in 12.5 wt. %. A primary coil 24 comprises a wire body coated with PET (polyethylene telephthalate), silicone or wax as a separating member, and is wound around the primary spool. The growth of trees in the primary spool 23 restricted even when electrical discharges occur between a secondary coil and the primary coil and the primary spool is eroded by the electrical discharges, because silica is added in the primary spool.

Abstract: This invention aims at producing a cold rolled thin sheet having excellent surface quality from a cast strip of a Cr--Ni type stainless steel cast strip by a thin casting method. The production method of the invention comprises the steps of continuously casting a Cr--Ni type stainless steel to a cast strip having a thickness of not greater than 10 mm by using a continuous casting machine the cast mold wall surface of which moves in synchronism with the cast strip; hot rolling the resulting cast strip at a temperature within the range of 900 to 1,200.degree. C. at a reduction ratio of 10 to 50%; carrying out, subsequently, heat-treatment at a temperature within the range of 1,200 to 900.degree. C. for at least 5 seconds; coiling the hot rolled cast strip at a temperature not higher than 600.degree. C.; descaling the rolled cast strip; cold rolling the cast strip; conducting annealing, pickling or bright annealing; and conducting skin pass rolling, whenever necessary.

Abstract: In continuous casting a thin carbon cast strip, the scale formed thereon is made thin and made to have a composition suited to working such as cold rolling and pressing. Moreover, an apparatus for inhibiting scale formation is simplified, and the consumption amount of an inert gas is reduced. The cast strip is thus produced efficiently. A carbon steel containing up to 0.5% of C is cooled and solidified by a pair of cooling drums to give a thin cast strip having a thickness up to 10 mm. The cast strip is introduced into a seal chamber, where the strip is held in an Ar gas atmosphere containing up to 5% of oxygen through a temperature region to at least 1,200.degree. C., and the strip is cooled at a rate of at least 10.degree. C./sec through a temperature region to 750.degree. to 800.degree. C., followed by coiling the strip in a coil form with a coiler at a temperature of at least 500.degree. C. and up to 800.degree. C. Furthermore, the atmosphere is formed with a nitrogen gas or exhaust gas.
