a pin lifting system is disposed below the surface of the esc using the example embodiment pin lifting system 1100 presume that arrow 1502 of fig1 represents the ideal longitudinal axis of pin holding shaft 1104 wherein the longitudinal axis of pin 1102 is normal to the upper surface of esc 106 in this example further presume that pin holding shaft 1104 is tilted such that end portion 1124 touches second bearing portion 1112 at point 1146 as illustrated in fig1 whereas first bearing 1110 touches outer housing portion 1108 at point 1148 in such a case the longitudinal axis of pin holding shaft 1104 actually is parallel with arrow 1504 of fig1 in this example therefore pin holding shaft 1104 is tilted by an angle u03c6 in this example let d u2032 be the distance between first bearing 1110 and second bearing portion 1112 when pin lifting system 1100 is in the first state the spacing u03b4 1 u2032 1506 is the spacing between first bearing 1110 and outer housing portion 1108 which is additionally illustrated as distance 1302 in fig1 as such in fig1 distance d u2032 and spacing u03b4 1 u2032 1506 are related to angle u03c6 as therefore with known a distance d u2032 and spacing u03b4 1 u2032 1506 an initial maximum tilt angle u03c6 u2032 of pin holding shaft 1104 may be calculated unlike the conventional pin lifting system discussed above with respect to fig5 and 6 in a pin lifting system in accordance with an aspect of the present invention the tilt angle of.
