A thin strong anode is made with an embedded end of a multi-strand single sleeve insulated wire and is molded from a three part composition of polymer, carbon and silica gel. The anode is thin, about 3/32 of an inch thick, and about an inch and a half in diameter. The anode is made in circular or other configuration. The peripheral wall of the anode has dimples, which are engaged by snaps projected inward from walls of a low profile capsule. The conductor passes through an opening in the side wa...

An autotensioner comprises a torsion coil spring interposed between a base and a rocking arm, and a tubular bushing provided between an inside surface of the base and an outside surface of the rocking arm. The torsion coil spring pushes and biases the rocking arm toward the bushing, and brings the pushing direction substantially in coincidence with the axial load direction of the force, acting on a stepped bolt supporting the rocking arm, from a belt. When the belt tension becomes high, the arm ...

A thin transformer includes a hollow coil bobbin around which a coil is wound, an iron core provided to pass through a portion of the coil bobbin, and a terminal section having several terminals electrically connected to drawn-out lines of the coil and electrically and mechanically connected to a circuit board, the terminal section disposed adjacent to the coil bobbin below the iron core and provided at the terminal section such that a first portion of each terminal connected to a corresponding ...

Thin films are formed by formed by atomic layer deposition, whereby the composition of the film can be varied from monolayer to monolayer during cycles including alternating pulses of self-limiting chemistries. In the illustrated embodiments, varying amounts of impurity sources are introduced during the cyclical process. A graded gate dielectric is thereby provided, even for extremely thin layers. The gate dielectric as thin as 2 nm can be varied from pure silicon oxide to oxynitride to silicon ...

A cushioning material 8 is stretched over a frame 6 by engaging only front and rear edges of the cushioning material 8 with the frame 6, thereby applying a tension to the cushioning material 8 substantially only in the longitudinal direction thereof.

The contactor comprises a fixed contact plate (14), a moveable contact plate (16) and means for retaining the two contact plates (14, 16). The moveable contact plate (16) is resiliently deformable between a position remote from the fixed contact plate (14) and a position in contact with the fixed contact plate (14). The retaining means comprise an adhesive insulating sheet (18) which is interposed between the two contact plates (14, 16), which sheet (18) adheres along the two opposing faces ther...
