    Abstract: An index signal output device where a magnetic flux detector is moved in the direction of a relevant tangent to the circumference of a rotor yoke so that the phase difference between an index signal detected by the magnetic flux detector and an index reference signal previously recorded on a floppy disk is within a prescribed range. The lead terminals of the magnetic flux detector are connected to detection signal output terminals on a printed circuit board, and the magnetic flux detector is moved for adjustment in the direction of the tangent by flexing the lead terminals using a tool.

    Abstract: A decoupling capacitor is mounted on a thin auxiliary board and connected by metallization traces on the board to a single pair of plug-in contacts press-fitted into a pair of apertures in a pair of integral tabs extending from the board. The auxiliary board and capacitor height is not more than about 0.070 inches. The plug-in contacts are pluggable into a pair of sockets in a printed circuit board. The auxiliary insulative board with its attached capacitor is sandwiched between a surface of a printed circuit board having a plurality of sockets, and the underside of a dual-in-line (DIP) integrated circuit package. At least two leads of the DIP package are inserted into the pair of insertable contacts in the auxliary isulative board while the remainder of the DIP package leads are inserted directly into other sockets in the printed circuit board. In one embodiment, other DIP leads pass through clearance holes in a second pair of integral tabs. Another embodiment provides for redundant capacitors each connected to separate pairs of contacts on the auxiliary board for interconnection of two ground leads and two power leads of the DIP to respective PC board sockets.
