摘要： The invention provides a shock absorbing structure of a railway vehicle capable of ensuring a doorway (escape port) region while absorbing collision energy during collision. The impact caused when a railway vehicle experiences collision is transmitted via an end structure (30) constituting the railway vehicle, a roof structure end section (42), an underframe end section (52) and a second doorway frame (74) to an upper third doorway frame (76a) and a lower third doorway frame (76b). When the impact exceeds a predetermined level, the roof structure end section (42), the underframe end section (52), the upper doorway frame (76a) and the lower doorway frame (76b) disposed in the crushable region (200) are crushed and plastically deformed in the longitudinal direction of the railway vehicle (1), absorbing the shock during the process. A width (L1) of the doorway section (60) after absorbing shock becomes smaller than a width (L0) of the doorway section (60) prior to absorbing shock, but the first doorway frame (72,72a,72b), the roof structure (40) and the underframe (50) disposed in the survival region (100) are not crushed, so that the doorway width (L1) can be ensured as an escape port.

摘要： In a magnetic disk drive for reading two or more positional information signals of multi-phases, a positional signal that is always continuous even at switching points (CH) where signals of different phases (N, Q) are switched and excellent in linearity is produced in order to precisely position the head (9) at an arbitrary point on a track. N' signal and Q' signal are calculated at each sampling time from the equations N' signal = N signal/ (| N signal | 2 + | Q signal | 2 ) Q' signal = Q signal/ (| N signal | 2 + | Q signal | 2 ) so that the positional signal is normalized at the intersections between N signal and Q signal, and these positional information signals are connected so that the head can be positioned properly.

摘要： The invention provides a shock absorbing device capable of starting and promoting crushing of energy absorbing members during elastic deformation of the energy absorbing members receiving compressive load immediately after collision, so as to reduce the peak load during collision and reduce the impact force or acceleration operating on passengers and crew. A railway car has a shock absorbing device including an energy absorber 100 for absorbing collision energy by crushing during collision placed at an end of an underframe. Projections 103 formed at a leading end portion 102 of the energy absorber 100 and a pipe body 110 as trigger member are provided as a trigger mechanism for starting and promoting crushing of the energy absorber 100 when the energy absorber 100 receives compressive load immediately after collision and deforms elastically. The operation of the trigger mechanism enables the energy absorber 100 to start crushing while being elastically deformed, so as to prevent the further progression of elastic deformation causing increase of the peak load during collision.

摘要： The invention provides a transportation device having a shock absorbing device with a reduced non-collapse region. Shock absorbers 14 and 17 constituting a shock absorbing device 10Aprovidedon a transportationdevice is connectedrespectively to shock absorbers 17 and 20 disposed rearward therefrom via connecting members23and 26having ashtray-like cross-sectional shapes. The shock absorber 20 disposed at the rearmost position is connected via welding to a base 29. Collapse regions 15, 18 and 21 of the shock absorbers 14, 17 and 20 are collapsed by the load applied to the shock absorbers 14, 17 and 20, and their lengths are shortened. Non-collapse regions 16 and 19 of the shock absorbers 14 and 17 overlap respectively with the non-collapse regions 19 and 22 of the shock absorbers 17 and 20 disposed rearward therefrom. Therefore, the non-collapse regions 16, 19 and 22 fit within a recessed portion of the connecting members 23 and 26, and the overall longitudinal length of the non-collapse regions of the shock absorbing device can be shortened.
