Patent DE-19809886-A1 (DE)
Inventor: RYCHLAK STEFAN
IPC: H03K17/968
Filed: 1998-03-07
Abstract: The invention relates to an electronic device, especially a car radio, comprising a microprocessor (1) and operator buttons (12, 13) which can be illuminated by light sources (7, 8). The functions of illumination and detection of the operating status of the operator buttons (12, 13) are associated with each other as follows: the light sources (7, 8) can be successively, cyclically supplied with control pulses as controlled by the microprocessor (1). Each operator button (12, 13) has a light receiver arrangement (15, 17, 19) which can be optically connected to the light source (7, 8). The optical connection between the light receiver arrangement (15, 17, 19) and the light source (7, 8) can be modified by the activation of the corresponding operator button (12, 13) and the microprocessor (1) is initialised for the allocation of the output signals of the light receiver arrangements (15, 17, 19) to the cyclically emitted pulses.

Patent DE-19821231-A1 (DE)
Title: Selection impact control system for vehicle automatic drive
Inventor: TAKIGUCHI MASAHIRO
IPC: F16H61/06
Filed: 1998-05-12
Abstract: The control system has an engaging element inserted on the basis of the application of an hydraulic pressure when the gear is switched from neutral to drive mode. The system has a selection determining section (20). This determines whether the gear has actually been switched from neutral to drive. A detector detects when a drive pedal has been pressed down. A control section gradually increases the hydraulic pressure from a first low level, which is maintained before the pedal is pressed, to a second, higher level which corresponds to the actual low pressure value of the pedal. The control section increases the pressure from the low level to the second, higher level when the detector detects that the pedal has been pressed down directly after determining the change from neutral (N) to drive (D).

Berlac) is immersed in the solution, dried and calcined for one hour at 140 deg C. The ruby pigment formed is stirred into the Berulan 43.999.000 (Fa. Berlac). 5% of the dye solution is stirred into the lacquer before processing and the required flow viscosity adjusted with the solution according to lacquer and processing method. The lacquer is lacquered with ground silver. Clean lacquer is further applied to the precious stone lacquer, and polished.

Patent DE-19855734-A1 (DE)
Inventor: LEIPELT RUDOLF
IPC: F02B27/02
Filed: 1998-12-03
Abstract: The invention relates to an adjustable suction pipe, especially for supplying combustion air to an internal combustion engine. The collector chamber of the suction pipe is arranged in the actuating device which is essentially configured in a cylindrical manner. Due to its construction, this collector chamber is provided with a larger volume than required for the air supply. This means that the chamber is not used efficiently. Thus, the invention provides for the collector chamber in the actuating device to be used in such a way that additional components of the suction tract can be arranged therein. This can be achieved by arranging a resonator chamber (20) in the collector chamber (11). Said resonator chamber is connected to the air supply system by drill-holes (19). This provides for a better utilisation of the chamber which is an advantage if only a limited space for construction is available. Furthermore, less weight is used by virtue of the greater compactness of the suction system.
