Abstract: Vehicle steering column ride down apparatus to guide the direction of steering column collapse in the event of vehicle crash includes a first part for fixedly mounting to a support such as a cross car beam and a second part for coupling to a steering column assembly. At least one of the parts has one or more tracks to act as guides and the other part has structure that runs in the one or more tracks. The apparatus also includes a tightener to tighten the two parts, one upon the other, to provide a predetermined frictional resistance at least to initial relative break-away movement of the two parts in the event of vehicle crash. Each track may be constituted by at least one slot. Coated plates can be clamped between flanges of the parts, which are each in the form of brackets to provide further initial frictional resistance to the initial relative break-away movement of the two parts.

Abstract: An electron-beam exposure mask that is able to realize the required pattern transfer accuracy independent of the deflection distortion and aberration of an electron beam. This mask includes a substrate with a first area and a second area, a first plurality of cell apertures formed in the first area of the substrate, and a second plurality of cell apertures formed in the second area of the substrate. The first area of the substrate is designed so that a charged-beam irradiated to the first area has a deflection angle less than a reference angle. The second area of the substrate is designed so that a charged-beam irradiated to the second area has a deflection angle equal to or greater than the reference angle. Each of the first plurality of cell apertures corresponds to fine patterns necessitating high pattern transfer accuracy. Each of the second plurality of cell apertures corresponds to rough patterns unnecessitating the high pattern transfer accuracy.

Abstract: A vehicle steering telescopic shaft having a male shaft and a female shaft so fitted to each other as not to be rotatable but to be slidable. First torque transmitting members are disposed between the male shaft and the female shaft, and roll when the male shaft and the female shaft make relative movements in axial directions. Elastic members are disposed adjacent in a radial direction to the first torque transmitting members and restrict them when rotated and apply a pre-load to the male shaft and the female shaft through the first torque transmitting members when not rotated. Second torque transmitting members are provided between the male shaft and the female shaft, and slide when the male shaft and the female shaft make the relative movements in the axial directions, and transmit a torque when rotated.
