摘要:
An individual metallic, electrical conductor is terminated by heating one end thereof to form an enlarged molten mass, followed by cooling and subsequent shaping of the mass to form a terminal. Multiple conductors are spliced by heating adjacent ends thereof to form an enlarged, common molten mass at the end of each conductor. Alternatively, adjacent ends of multiple metallic conductors may be spliced by heating the ends thereof to form a molten mass at the end of each conductor followed by plunging the molten masses into one another.

A steering column mounted stalk switch apparatus includes an elongated shaft having a hub fixedly mounted at one end. The hub fixedly engages one end of a hollow knob housing. An aperture is formed in the opposite end of the housing and movably receives a button therein having at least one electrical contact mounted thereon. A carrier is slidably mounted in the housing for movement between a plurality of discrete positions and includes a projection extending externally through a side wall of the housing. Electrical contacts are mounted on the carrier and engage conductive tracings on the circuit board as the carrier is moved between the discrete positions.

An electrical terminal having a wire clamping tab connected thereto by an essentially thin neck portion about which a wire coated with a resin-type, high temperature insulation is adapted to be wound so that, when the tab is bent back against the terminal by opposed, energized electrodes to clamp a portion of the wire extending from the neck portion therebetween, resistance of the latter to flow of current heats both the neck portion and the wire wrapped therearound sufficiently to explode the insulation from the wire to assure a good electrical connection. At the same time the relatively large area of the terminal and its clamping tab maintains the clamped portion of the wire below its annealing temperature so that it is resistant to breakage in use.

An improved deck lid lock with remote release for motor vehicles. The deck lid lock employs a solenoid operated rotatable armature which acts directly on a leg of a rotatable latch plate which engages a lock bar. On energization of the solenoid, the armature is attracted to the solenoid causing it to disengage the latch plate so that the deck lid may be opened. When the deck lid is closed, the lock bar is engaged by the latch plate which is returned to its normal latched position in engagement with the armature. The deck lid lock further includes a rotatable key cam which acts on the armature to enable release of the deck lid through conventional external key actuation.

A non-involute gear used in a gear pair. A first gear has a plurality of radially extending, circumferentially spaced teeth, each with a generally cylindrical, arcuate shaped end surface. A second gear has a plurality of spaced, non-involute shaped teeth. Each tooth of the second gear is formed with opposed base faces disposed at an identical radius. A pair of flats extend in parallel from the ends of each circular base face and terminate in inwardly extending, end portions extending from the flats to the top land of each gear tooth. A tooth space is formed between two adjacent non-involute gear teeth having a semi-circular base portion formed by the opposed circular base faces of two adjacent gear teeth and two parallel flat portions formed by the pair of parallel flats extending from the semi-circular base portion which combine to form a generally U-shaped space for receiving a gear tooth on the first gear.

A variable force solenoid valve assembly is provided for use in an automatic transmission controller for controllably reducing a fluid inlet pressure to a desired outlet control pressure. The invention includes a variable force solenoid assembly secured to a valve body assembly. The valve body assembly includes a spool valve having three radially extending lands which translates within a valve body central bore in response to movement of an armature assembly provided in the solenoid assembly. Movement of the spool valve generates first and second flow restriction for controllably regulating the reduction of inlet pressure to control pressure. In addition, various improvements in spool valve design are described including a design which provides positive damping of the spool valve so as to attenuate "self-excited" oscillation thereof.

A collapsible steering shaft apparatus includes first and second telescopingly arranged steering shaft members. A plurality of longitudinally extending projections are formed in one of the steering shaft members and engage a plurality of longitudinally extending grooves formed in the other steering shaft member. The mating projections and grooves join the steering shaft members together for longitudinal sliding movement under external forces exerted on the steering shaft apparatus. The mating projections and grooves also prevent rotation of the two steering shaft members relative to each other and insure that the two steering shaft member rotate together as a unit without backlash upon rotation of the vehicle steering wheel. A method of forming the projections and grooves in the tubular steering shaft members is also disclosed.

A solenoid having a coil that includes the usual bobbin or spool, winding and armature in combination with a flux collector that is uniquely formed and associated with the coil bobbin and with the armature to maintain essentially precise concentricity between the flux collector and the armature and the intervening air gap of a uniform minimum width dimension so as to minimize the size of the coil and loss of armature power in use while at the same time assuring an adequate and reliable operating force in the armature.
