Title: A method for controlling two adjustment devices of a motor vehicle seat
Inventor: GMEINER GUNTER
IPC: B60N2/02
Filed: 1990-03-30
Abstract: A method for controlling two adjustment devices 1.1.1 and 1.0.1 of a motor vehicle seat are described, which devices are assigned to the longitudinal movement of the seat 1.2 and the tilting movement of the seat back 1.1 and, activated by positioning switching elements 2, 3, 4, move the motor vehicle seat into corresponding- specifiable - set positions, switching means 7 associated with the seat back 1.1 which block the associated adjustment device before the seat back runs into an obstacle lying in its range of adjustment. In order to optimize the sequences of motions, in the case of a rearward tilting movement of the seat back 1.1 initiated by the positioning switching element 2 and shortly before the seat back runs into the obstacle 6, with the blocking of the adjustment device 1.1.1 for a further thing movement of the seat back a longitudinal movement S of the seat forwards is here automatically initiated by the switching means 7, the seat back thereby moving out of the switching range 7.1 of the switching means 7 again, and, in addition to the longitudinal movement of the seat, the rearward tilting movement is also continued again, either until the next time blocking occurs or until the set lowered position of the seat back is reached, in which position the longitudinal movement of the seat is then also switched off.

Title: Liquid cooling device of projection CRT
Inventor: PARK JAEBUM
IPC: H01J29/89
Filed: 1991-07-03
Abstract: A heating coil 8 is provided for the liquid coolant in a projection CRT so that it quickly attains its operating temperature. The liquid cooling device for attaching to the GRT faceplate has a radiator (2) having a space in its inner portion and a transparent plate attached to the front of the radiator to seal a space (4) from the outside. A heating coil (8) is embedded around the inner portion of the space (4) of the radiator, and this heating coil is controlled by a power supply circuit, Fig. 3 (not shown), using a temperature sensor 14 for detecting the temperature of the coolant in order to heat the coolant quickly to a stabilizing temperature of 60 SIMILAR  80 DEG C, thereby shortening the picture appearance time of the projection CRT. When the coolant is heated to the stabilizing temperature, the temperature-control circuit cuts-off the electric power to the heating coil and allows continued heating of the coolant by the heat generated through the action of the projection CRT. <IMAGE>
