Title: Method and device for installing cables
Inventor: GRIFFIOEN WILLEM
IPC: G02B6/52
Filed: 1996-07-23
Abstract: The invention pertains to a method of installing cables (2) in cable ducts (6) using installation devices (1; 1a, 1b, 1c) propelling the cables (2) into the ducts (6). In accordance with the invention, the installation devices (1; 1a, 1b, 1c) are powered by means of pressurized fluid, such as air, transported through the ducts (6). This results in a smaller number of compressors (4) and operators being necessary. For transporting the pressurized fluid, the duct (6) in which a cable (2) is installed and/or parallel ducts may be used. In a duct section (e.g. 6a), the feed direction of the cable (.fwdarw.) may coincide with, or be opposed to, the transport direction of the fluid (.fwdarw.). The invention further provides installation devices (1) for use in the method.

Title: Method and device for recording data in an optical memory card
Inventor: KIMURA YASUYUKI
IPC: G11B19/04
Filed: 1997-11-10
Abstract: A method and a device for recording data in an optical memory card which facilitate judgment between an unrecorded region and a recorded region in the optical memory card and which prevent double writing. Record pits are formed so that data to be recorded on the optical memory card is recorded in the same way as when recorded in the MFM-RZ modulation system.      Data that was recorded in the NRZI-RZ modulation system is reproduced and the modified to record in the MFM-RZ modulation system. This method forms the record pits at least every two recording intervals or less in the recorded region in the optical memory card, making it possible to fudge the unrecorded region of the optical memory card from the recorded region according to presence or absence of the record pits and thereby preventing double writing.

Title: Motor vehicle steering column and seat belts with a protection device
Inventor: GO GIOK DJIEN
IPC: B60R19/00
Filed: 1998-03-10
Abstract: As yet heads of belted passengers, when thrown forwards in real-world front collisiones, crush into a steering wheel, dashboard, windshield or backrests of front seats despite deployed airbags. A protective device is equipped with wires, energy-absorbing, vibration-dampening delimiters, a collapsible upper portion of steering column and a pair of independently operating piston devices. At least one piston rod deflects in any front or rear collision. That deflection is exploited to pre-tension seat belts of belted passengers up to a predetermined length of seat-belt retraction and to retract the collapsible upper portion out of the head-injury area.   In the second feature of invention, in order to prevent buckling, achieve the highest efficiency of energy absorption and lower impact forces, to which passengers and delimiters are exposed, a cone-shaped hub reams, folds and buckhes a deformable longitudinal runner during which the piston rod, guided by a bearing box and the hub, loosely guides that runner. In the third feature, in order to further lower impact forces, dampen vibration and prevent belted passengers from strangulation mating members of the delimiters perform work of deformation and friction, block further movement of seat-belt wire, deflected by the moving piston rod, in excess of that predetermined length of seat-belt retraction and maintain lengths of all the retracted seat belts.
