Title: Static discharging device for a VCR head drum
Inventor: AHN SEONG-ICK
IPC: G11B15/00
Filed: 1996-11-29
Abstract: The present invention is related to a discharging device for head drum, and more particularly to a discharging device, wherein the static electricity which occurred from the head drum is effectively discharged using the discharge device. The one end of bracket is fixed on a main chassis by a screw, and the other end forms a bracket protrusion. Coil spring is put on the end of the bracket. One end of leaf spring is put inside the coil spring together with the other end of the bracket, and the other end forms a leaf spring protrusion. The tip is installed between the other end of the leaf spring and the head drum. Static electricity transmitted to tip is transmitted to bracket via leaf spring. Then, static electricity is discharged through main chassis. Thus, this discharging device can improve productivity since extra riveting or bonding is unnecessary. Also, the grounding property of head drum is improved because the close adhesion between the tip and revolving shaft is ensured by coil spring.

Title: Low noise NMOS buffer with stepped pull-down transistor gate drive
Inventor: LIN YU-CHANG
IPC: H03K19/003
Filed: 1995-10-25
Abstract: Switching noise in an NMOS buffer is reduced by turning on the pull-down transistor 404 in two stages. An initial drive potential is applied to node PD by Q21 and Q22, and then the PD voltage is increased to Vcc when delay circuit BL1 turns on Q26. The initial drive potential is equal to VR-VT, where VR is a reference voltage and VT is the threshold voltage of Q21. The delay is shortened when signal LV bar is low, indicating that Vcc is 3.3 V. The pull-up transistor 402 is also driven in two stages.

Title: Sealing and wiping vehicle door window glass
Inventor: HELLER NORBERT
IPC: B60J10/04
Filed: 1997-01-15
Abstract: A sealing lip (34) is formed by part of the outside wall of a first flexible chamber (36). A wiper blade (40) is mounted on the outside of the flexible wall of a second flexible chamber (38). When the glass (12) is stationary, the first chamber (36) is in an expanded state to ensure that the sealing lip (34) is in firm sealing contact with the surface (12A) of the window glass (12). When the window glass starts to move, the first chamber (36) is partially evacuated so that the sealing lip (34) is moved clear of the surface (12A) of the glass. When the glass stops, the first chamber (36) is re-expanded by increasing its internal pressure. When wiping of the glass surface (12A) is to take place, the second chamber (38) is partially evacuated, and this causes the wiper blade (40) to be pivotted into wiping contact with the glass surface (12A).

Title: Axially locked, radial displacement released, bearing and housing
Inventor: SCHINDLER JENS
IPC: F16C35/067
Filed: 1999-01-29
Abstract: A bearing unit 50 comprises a bearing housing 58 which has bearing 64 which is radially movable in one direction. Movement of the bearing 64 in said radial direction disengages the bearing 64 from behind an axially acting locking rib 68 for quick and easy replacement of the bearing 64. The bearing can be radially biased towards the operative position behind the locking rib 68 by prestressing of loop belts 22, 24 of a continuous conveyor, a steel or rubber-elastic spring cushion (84 fig 8), a leaf spring (86 fig 9), locking screws/rods (88/90 fig 10) or a wire bow spring (figs 11, 12). The radial extension of the locking rib 68 is smaller than the radial clearance between the bearing 64 and the fitting aperture 70 of the housing 58. There may be two such bearings 64 applied to the housing, each being biased in opposite radial directions with locking ribs 68 facing opposite directions. The bearings 64 may be ball, roller or sliding bearings.

Title: Colour developer with diffusible development inhibitor
Inventor: TWIST PETER JEFFERY
IPC: G03C7/407
Filed: 1999-10-15
Abstract: The developer is used to develop colour photographic elements, e.g. colour photographic papers. Rapid development, e.g. less than 25 seconds, is aided by the presence of a selectively diffusible reagent, such as a development inhibitor. The developer inhibitor, preferably comprises two active inhibitor (INH) groups, for example heterocyclic rings which include mercapto (-SH), seleno (-SeH), or Telluro (-Th) groups, linked through a leaving group (LG) to a linking group (LINK). The development inhibitor diffuses into the top layer of the multi-colour material, and leads to more uniform development of the three colour records within the photographic element. The diffusion characteristics of the development inhibitor are carefully designed to allow diffusion into the top layer of the photographic element, e.g. the red-sensitive emulsion layer of colour paper.

Title: Synchronizer with force limiter which prevents damage
Inventor: SMITH CARL CHRISTOFER JOHN
IPC: F16D23/06
Filed: 1999-12-08
Abstract: A synchronizer comprises cone clutch surfaces 24, 48 which are engaged by an operator shift force and force limiting means 54, 56 having ramp surfaces 38b-38e that cooperate with shoulders 64b, 64c, 66b, 66c that are rigid with tabs 64a, 66b connected to baulkrings 40, 42. During an upshift, when a torque exceeds a predetermined amount, spring 72 is compressed enough to allow surface 64d to contact ramp surface 38b. Any further increase in torque causes the surface 64d to move down ramp surface 38b thereby moving clutch surface 48 away from clutch surface 24 and reducing an engaging force therebetween to a predetermined amount. At this level of torque the spring 72 extends causing surface 64d to brake contact with ramp surface 38b. Angled blocker surfaces 36a, 44a on teeth 36, 44 transmit operator shift force to the cone clutch surfaces 24, 48.
