Filed: 1990-11-30
Granted: 1994-06-28
Abstract: The substrate current generated during operation of a bit- line compensator may be reduced by adapting PMOS transistors which have an ionisation coefficient in their hole carrier which is smaller than that of NMOS transistors so as to maintain a pair of bit lines at the same potential before operation of a directional amplifier.  In this way, the substrate of voltage may be stabilised, reducing the substrate current during operation of the bit line compensator.  Fig. 3 <IMAGE>

Title: Coupling electrical connector - has snap rings connecting front and rear portions of sleeve
IPC: H01R/
Filed: 1973-06-13
Granted: 1979-04-10
Abstract: An easily disconnectable sleeve houses one half of a quick release or emergency release type connector assembly. The rear portion of the sleeve may be removed for access to the junction between the electrical contacts of the connector and the incoming wires, thereby permitting the electrical circuitry to be checked without disconnecting the connector assembly.

Abstract: The present invention provides an apparatus for transferring knitted fabric from needles of a first knitting gauge to needles of a second knitting gauge. A row of parallel, elongate points are provided each being arranged parallel to one another and secured at each end to a movable frame. The bands pass through respective slots in two trick bars with the points being located between the two bars so that movement of the bands in unison carries the points from one trick bar to the other. If the slots in the respective trick bars are at the two selected knitting gauge then passage of the bands through the slots adjusts the spacing of the points from one gauge to the other.
