Title: Video signal magnetic disc recording and playback appts. - processes input signal to provide modifying action to that is added to original signal to improve quality when speed variations exist.
Inventor: SATO KOICHI
IPC: G11B20/22
Filed: 1993-09-03
Abstract: The magnetic disc system for video recording and playback receives an input signal (Y+S) by a separating stage (10) to extract synchronising data (S). This is received by a burst signal generator (20) that produces an output gated through a burst signal gating stage (30) to be added to the original signal (35). The gating stage uses the output of a clock generator (40). The playback process processes (90) the signal and feeds it to a separator stage (100). Here the signal is used by a phase locked loop (120) that uses the modified video signal. USE/ADVANTAGE - Provides high quality playback, even when recording medium drive exhibits speed fluctuations on video signal recording or reproducing.

Patent DE-4335344-A1 (DE)
Inventor: RENNINGER GERD DIPL ING
IPC: B60T7/12
Filed: 1993-10-16
Abstract: A method for monitoring the speed of an automatically controlled vehicle during braking, which vehicle is equipped with a position (displacement) measuring device and an on-board control unit. The monitoring is performed by desired/actual speed comparison, in which the respective desired speed is calculated continuously from the distance covered by the vehicle and its prescribed braking curve. In order to obtain desired speed values at the density required for reliable monitoring of the braking curve, instead of calculating the square root, as is otherwise conventional, the method carries out an approximate integer computation on the basis of a secant circuit with equidistant corner points which is approximated to the square root function.

Title: Fifthwheel coupling with means of adjusting the play in the coupling
Inventor: JAKOB LOTHAR
IPC: B62D53/08
Filed: 1994-04-09
Abstract: In the case of a fifthwheel coupling (10) with a coupling plate (12) and a latch (24, 28), which is in operative connection with a hand-lever bar (36) and is intended for a lock piece (16) of a coupling fastener (14), the end position of the latch (24, 28) can be changed in order to adjust play in the coupling fastener (14). For this purpose, on the hand-lever bar (36) there is fastened releasably a stop element (94) which is to be positioned in accordance with the end position of the latch (24, 28), which end position is to be changed. The stop element (94) has a stop plate (92) which, when the coupling fastener (14) is closed, bears with a stop edge (93) against a mating surface (81) in the coupling plate (12). In order to adjust the play in the coupling fastener the easily accessible stop element on the hand-lever bar is offset outwards. The stop element, which is visible from the outside, serves at the same time as a means of verifying that the coupling fastener is closed correctly. The play between the stop and coupling plate is always the same and the hand-lever bar has no weak point. <IMAGE>

Title: Vehicle headlamp
Inventor: UCHIDA NAOKI
IPC: F21V11/16
Filed: 1994-04-20
Abstract: A vehicle headlamp (headlight) is proposed which has a reflecting surface which is curved to the outside, a lens which covers the front side of the reflecting surface, and a heating filament which is arranged at a predetermined location on the reflecting surface, as a result of which the light emitted by the heating filament is reflected at the reflecting surface for the purpose of radiating a dipped beam. The headlamp has, in addition, an auxiliary reflecting surface which is provided at a location outside the region which extends from the heating filament and covers the effective reflecting surface of the reflecting surface. The auxiliary reflecting surface is arranged essentially horizontally and essentially parallel to the direction of radiation. The vehicle headlamp having the construction described above can therefore produce beams for illuminating characters (signs) arranged overhead, from the light which is reflected at the auxiliary reflecting surface, whereas no dazzling light is emitted from the auxiliary reflecting surface for an approaching vehicle. In addition, this headlamp does not limit the design possibilities for the lens.
