Abstract: PCT No. PCT/DE97/01989 Sec. 371 Date May 6, 1998 Sec. 102(e) Date May 6, 1998 PCT Filed Sep. 8, 1997 PCT Pub. No. WO98/11596 PCT Pub. Date Mar. 19, 1998A radiation source, in particular a discharge lamp suitable for operating a dielectrically hindered pulsed discharge by means of a ballast, has at least one electrode separated by dielectric material from the inside of the discharge vessel. By appropriately designing at least one of the electrodes and/or the dielectric material, local field reinforcement areas are created, so that during the pulsed mode of operation one or more dielectrically hindered individual discharges are generated exclusively in these areas, maximum one individual discharge being generated in each area. These areas are obtained in particular by shortening the spacing in locally limited areas, for example by providing on one of the electrodes hemispherical projections which extend towards the counter-electrode. This measure achieves a timestable discharge structure with a high useful radiation effectiveness uniformly distributed throughout the discharge vessel.

Title: Inflatable tubular torso restraint system
Inventor: ROMEO DAVID J
IPC: B60R22/14
Filed: 1997-07-02
Abstract: PURPOSE: An inflatable tubular torso restraint system is provided to reduce the extent and severity of injuries during a crash by restraining the body of an occupant in a vehicle. CONSTITUTION: An inflating component is a braided tube(101) linked to a gas generator and crash sensor. When an impact is detected, the gas generator is ignited, inflating the braided tube. As the braided tube inflates, the diameter of the tube increases significantly and its length decreases significantly, due to the orientation of the fibers comprising the braided tube. The contracting tube gives pretension to the seat belt system by pulling any slack out of the seat belt system. The inflated structure restricts the forward motion of an occupant and distributes crash loads over a larger occupant surface area to reduce both primary and secondary injuries. In a side impact the inflated structure restricts occupant motion, distributes crash loads and provides head protection.

Abstract: PURPOSE: A guiding roller assembly of sliding door of automobiles, installed on one side of a sliding door, moves on a guiding rail to guide opening and closing of a slide door so as to prevent a vertical roller moving rotationally contacting a rail face from deviating from a supporting pin. CONSTITUTION: A guiding roller assembly of sliding door of automobiles is fixed on one side of the sliding door(1) and comprises a roller bracket(52), a horizontal roller(55) and the vertical roller(57) and a deviation preventing part(58)(59) on one end inserted into a guiding rail(6) of a car body. The roller bracket(52) has the horizontal roller(55) and the vertical roller(57) extending to a horizontal direction and a vertical direction, respectively. The horizontal roller(55) and the vertical roller(57) engage rotatably with a horizontal roller shaft(54) and a vertical roller shaft(56), respectively, so as to move rotationally guided by guiding faces(62)(64) of the guiding rail(60). The deviation preventing part has a ring shaped protrusion(58) formed by the external surface of the vertical roller shaft(56) and a ring shaped groove(59) formed by the internal surface of the vertical roller(57) so as to accept the ring shaped protrusion(58) when the vertical roller(57) engages with the vertical roller shaft(56), and prevents the vertical roller(57) from deviating from the vertical roller shaft(56).
