IPC: H01L27/148
Filed: 1997-04-25
Abstract: A solid state image sensor comprises a semiconductor substrate 32 of a first conductivity type having one or more photosensistive pixels formed therein, the photosensitive area 20 of the or each pixel being formed by the semiconductor substrate and one or more impurity layers 33,34 of a second conductivity type formed within an active area of the semiconductor substrate. The photosensitive area has one or more edge portions defined by isolation 31 separating the active area of the semiconductor substrate from other active areas thereof, and the doping density of the impurity at the edge portion(s) of the photosensitive area is substantially restricted. A preferred embodiment is a CMOS photodiode sensor in which each pixel thereof includes a photodiode 20 formed by two N-type layers 33,34 in a P-type substrate. The lower N-type layer 33 is more heavily doped than the upper layer 34 and the edges of the lower layer 33 are set back from the edges of the upper layer 34. Alternatively, the lower layer 33 may be absent altogether. The layers 33, 34 are formed by the use of two or more different masks in the impurity doping process during manufacture of the sensor. Such a construction reduces dark-current leakage.

Title: Clutch slack adjuster utilizing self-loosening tendencies of a thread
Inventor: WEIDINGER REINHOLD
IPC: F16D13/75
Filed: 1998-09-10
Abstract: A clutch pressure plate module 10 comprises a diaphragm spring 18 acting on a pressure plate 10 via a wear compensating slack adjuster 24 which is held in position by a backlash sensing arrangement 30. The arrangement 30 comprises, for example, a bolt 32 having a head 40 with a bearing surface 42 cooperating with the adjuster 24 and engaging a counter bearing surface 48 of a slack detecting element, eg bolt 44, when friction lining wear occurs. The engagement of the bearing surface 42 and counter bearing surface 48 tilts bolt 32 in direction B 2 , while the clutch is engaged, and the adjuster 24 tilts the bolt 32 in an opposite direction B 1  when the clutch is disengaged. This alternative tilting, during engaging and disengaging of the clutch, in directions B 1 , B 2  causes the bolt 32 to rotate about axis L which results in self-loosening of thread 34 with thread 38, thereby allowing the adjuster 24, via sloping edges, to expand axially and take up wear. In other embodiments bolt 32 may be replaced by a nut which rotates about a pin fixed in the pressure plate (see fig 5) or clutch housing 12 may provide the counter bearing surface (see fig 6).
Patent GB-2341741-A (GB)
Title: Stabilisation of passband active filters
Inventor: TOLSON NIGEL JAMES
IPC: H04B1/04
Filed: 1998-09-18
Abstract: A calibrator for stabilisation of a passband active filter firstly sets a low level of filter supply current to assure filter stability while the filter is tuned to the required passband. The supply current is then gradually increased until the filter becomes unstable. The supply current level is held constant when filter instability is detected and the current is then reduced by a predetermined amount to maintain stability of the filter. Re-tuning of the filter may then proceed without risk of instability. May be used as part of a phase locked loop for operating channel selection in a radio.
