A normal/reverse mode changing mechanism for a tape transport apparatus comprises a mode selecting lever, cam arrangement, and an electromagnet, and one of two tape running modes is selectively obtained due to changing the number of current pulses supplies to the electromagnet. The mode selecting lever has such a function as to move a plurality of controlling members, such as a drive gear engaged selectively with one of the reel base gears, and a lever, which can selectively press one of the two pinch rollers against the corresponding one of two capstans for controlling the direction in which the tape is running. The cam arrangement has such a function as to hold the mode selecting lever selectively in one of two positions: a first position for obtaining the first tape running mode by a combination of a first pinch roller and a first capstan, and a second position for obtaining the second tape running mode by another combination of a second pinch roller and a second capstan. The electromagnet has such a function as to control the angle of rotation of the cam arrangement and the position of the mode selecting lever.

A method for leveling a metal strip performs a leveling operation by opening leveling rolls at a predetermined position relative to a welded joint and closing at a predetermined position relative to the welded joint. The tension exerted on the metal strip while the leveling rolls are held open is set at a given value in relation to the metal strip length where the leveling rolls are held open. The tension to be exerted on the metal strip while leveling is selected so that the tension may cause a given rate of elongation on the metal strip and thereby levels the metal strip. The leveling device is applicable for implementing the leveling process including a quick open and a quick close upon encountering welded joints of the strips. The leveling device includes features in that the leveling rolls as held open and thus released from the metal strip and self-propelled to rotate.

A method of and an apparatus for winding a wire around a toroidal core wherein one end portion of the wire is fixed in a predetermined position and the other end portion thereof is gripped, while leaving free a predetermined length from the leading end, by a gripping device which is moved to a position suitable for bringing the leading end substantially into alignment with a center opening formed in the toroidal core in the side of one surface thereof. After releasing the wire from the gripping device, the leading end of the wire passing through the opening and extending beyond the other surface of the toroidal core is gripped by a pull-out device which is moved to partially pull the wire out of the opening axially thereof, and the other end portion of the wire is again gripped by the gripping device while releasing the wire from the pull-out device. The gripping device is moved to the position to which it moved previously while tensioning the portion of the wire pulled out of the opening, whereby the wire can be fully pulled out of the opening and wound around the toroidal core.

A waterproof structure, which is for one connector fixed to a mounting hole of an automotive motor's metallic case and another connector fixed to a mounting hole of an automotive inverter's metallic case and connected to the one connector, comprises ring-shaped first and second packings. The first packing resides between the one case's surface and the one connector's surface that are orthogonal to a fitting direction of the connectors such that the one case's mounting hole is surrounded thereby to provide waterproof interface between the one case and the one connector. The second packing resides between the other case's surface and the other connector's surface that are parallel to the fitting direction. The second packing extends on an outer circumferential surface of the other connector to provide waterproof interface between an inner circumferential surface of the other case's mounting hole and the other connector's outer circumferential surface.

A driving apparatus includes a voltage applying unit, a light irradiation unit and a resistance control unit. The voltage applying unit forms a voltage applying circuit together with a pair of electrode layers of a photo-addressing type display element. The voltage applying unit applies a voltage between the pair of electrode layers. The light irradiation unit irradiates the photo-addressing type display element with addressing light. The resistance control unit controls a resistance to a current which flows in a direction to reduce a potential difference between the pair of electrode layers to be larger than that during a period in which the voltage applying unit is applying the voltage.
