A vehicular impact absorbing apparatus includes a pair of tubular guide rails having a guide slit longitudinally formed at the upper part of each guide rail fixed to the ground. Sliders are movably mounted in the guide rail at predetermined intervals, the upper part of each slider is laid on the upper part of the guide rail through the guide slit. Cushion units are mounted on the upper part of each slider. Each cushion unit is elastically deformed by vehicular impact while retracting along the guide rail. Cushion pins are mounted across the guide rails at predetermined intervals between the sliders that also absorb the kinetic energy of an impact by being broken by the rearward retracting slider. A stopper is installed around the rear end of the guide rail for stopping the retracting cushion units. A successive cushion and deceleration of the impact is possible in this arrangement.

The invention presents new methods of compression, transmission, and decompression of video signals providing increased speed and image quality. Methods based on wavelet transformation with decimation and time stamping can provide one-pass encoding of signals in which the amount of bits of information needed to be transmitted can be substantially reduced, thereby increasing the speed of transmission of digital signals over networks. Decompressing signals, along with interpolation methods to re-create portions of images of lesser importance in visual perception, can provide coordinated video and audio presentations of high quality in real-time over all kinds of networks.

A damper mechanism for a lockup device 7 is a device for mechanically transmitting a torque in a torque converter 1. A coil spring 58 is arranged in first and second windows 61 and 62 overlapping with each other, and is compressed in accordance with the relative rotation of drive and driven members 52 and 53.
