Abstract: a motor coil-shorting detecting unit is provided which determines the existence of a short. The coil shorting detecting unit includes a current sensor for detecting the value of current supplied to a motor from a power source, and a controller for making the shorting determination of coils by comparing a detected voltage or current with a pre-stored normal voltage or current.

Abstract: An object is to provide a wax composition for candles which is excellent in moldability in the production of the candles, enables the candles produced therefrom to be reduced in the bending and blocking, and which can be improved in releasability. A wax composition for forming candles, which comprises 100 parts by weight of petroleum paraffin wax and 0.1 to 0.3 parts by weight of a mineral oil, with said petroleum paraffin wax containing 97% by weight and above of a fraction which has 24 and above carbon atoms, having normal paraffin wax/non-normal paraffin wax ratios of at least 9 and having a melting point of 45 to 65.degree. C.

Abstract: A binder composition comprising a petroleum resin, an aromatic heavy mineral oil, a thermoplastic elastomer, an ethylene copolymer and a waxy substance has a high viscosity at 60.degree. C. and a low viscosity at high temperatures, and can provide a mixture together with aggregate having remarkably high compressive strength.

Abstract: An asphalt composition for use in road pavements is disclosed which comprises chiefly of an asphalt of natural or petroleum origin, a thermoplastic elastomer and/or a styrene-butadiene rubber and a low molecular weight polypropylene. These components are premixed or plant-mixed to form a reformed asphalt which is mixed with an aggregate to provide a paving material having increased compression strength, increased low temperature viscosity and decreased high temperature viscosity.

Abstract: A stripping-resistant asphalt composition comprising (A) an asphaltic material, (B) a reaction product of a maleic compound, such as maleic anhydride, and another organic compound, such as liquid polybutadiene, and (C) aggregate.

Abstract: An asphalt composition comprising an epoxy resin, a maleinated asphaltic material and, if desired, a curing agent for the epoxy resin.

Abstract: Upper and lower flap doors respectively hinged to an upper lintel member and to a lower sill member of a doorway frame constituting almost the entire side wall of the body of a van type motortruck to swing open respectively outwardly and upwardly to a horizontal position and outwardly and downwardly to a vertical position are intercoupled by a coupling device comprising two coupling mechanisms installed close to two posts constituting side members of the doorway frame, each coupling mechanism comprising members intercoupling the flap doors to synchronize their movements and cause gravitational forces acting thereon to counterbalance each other, thereby reducing the physical effort required for manual opening and closing of the doors.
