    摘要: A high force detent mechanism to selectively hold a control input lever in any selected position between neutral and its maximum travel in either direction. The high force detent mechanism includes a coil assembly connected to a control input lever and disposed in close proximity to a semi-circular member having a serrated edge defined thereon. An armature of the coil assembly has a first portion in driving contact with the serrated edge and a second enlarge portion having a latching surface disposed adjacent one of the first and second end faces of the coil assembly's detent coil. The size of the latching surface is larger than the size of the first portion that is in driving contact with the serrated edge. Consequently, the latching force generated between the latching surface and the one face of the detent coil is multiplied several time to create a detent holding force that is larger than the latching force.

    摘要: A variable position detent mechanism for latching a control lever at an infinite number of operating positions includes a semi-circular member connected to a support so that its axis coincides with the pivot of the control lever. An electric detent coil is connected to the lever at a location adjacent the semi-circular member so that energizing the detent coil magnetically latches the lever to the semi-circular member.

    摘要: A thin, continuous, flexible drive belt for a belt-driven data cartridge. The belt has a rectangular rib which extends longitudinally along the center of the face of the belt that contacts a tape pack contained within the cartridge. The ribbed belt allows the tape pack to operate at greater transport speeds and acceleration rates by creating a pair of air channels extending the full length of the contact area between the belt and tape pack, resulting in effective removal of air at the belt/tape pack interface.

    摘要: The invention deals with a method of electroding a poly(vinylidene fluoride) solid in a piezoelectric application. The electroding method entails surface preparation of the poly(vinylidene fluoride) by a variety of steps including plasma etching to create temporary molecular scale surface irregularities followed by sputtering a metallic layer before deterioration of the plasma etched surface. The chromium may be the initial metal sputtered, followed by a sputtered copper layer, followed in turn by at least one heavier electrodeposited conductive layer. The method may be conducted without deterioration of the piezoelectric properties of the material. The method has been found to provide very good adhesion between the electrode and the PVF.sub.2 surface.

    摘要: A technique facilitates evaluation of pipe. A sensor is positioned to examine a pipe and to obtain data on the pipe. The data obtained is analyzed on a processor-based system and compared to predetermined defect data. If the data obtained by the sensor sufficiently matches predetermined defect data, a defect is determined to enable performance of an appropriate action with respect to the pipe.
