Abstract: In a stator for an electric motor, insulating members are formed on laminated iron cores divided for each pole-tooth unit in the direction of the output shaft and windings are applied perpendicularly to the pole-tooth portions in a high-density alignment. After a predetermined number of the laminated iron cores are combined so as to form a cylindrical configuration, they are welded at the outer end portions of the dividing surfaces in the direction of lamination so as to construct an integral structure stator with rigidity, thereby enabling high densification of the windings (conductor space factor of 70%) and space-savings in the winding end portions. Further, as any joint portions between the pole-tooth portions are not necessary, reduction (5 to 10%) in motor efficiency due to such joint portions can be prevented, and, as any integrally forming by resinous members is not necessary, inter-winding short-circuiting is not caused. Welding may be replaced by adhesive bonding.

Abstract: In order to optimize combustion in a four-stroke spark-ignition engine with direct fuel injection, the conditions of charge flow are improved by providing the top surface of each piston with an essentially U-shaped guiding rib, which is open towards the exhaust side of the combustion chamber, fuel injection taking place into the concave area inside the guiding rib. The nozzle opening of the fuel injection device as well as the ignition source are positioned in the area of the cylinder center, i.e., preferably on different sides of the longitudinal center plane of the engine.

Abstract: A navigation system and a voice guidance method for carrying out a voice guidance of an intersection on a drive route when the user demands the voice guidance while a motor vehicle is running according to a preset drive route. In response to the output demand of the guidance information through an inputting unit, a control unit obtains a distance to the intersection and an advancing direction in the intersection and further reads out the corresponding sound data from a sound storing unit. This sound data is outputted through a speech synthesizing unit and a voice outputting unit.

Abstract: In a hydraulic operating mechanism for a convertible top, a pressure sensor (12) is incorporated into a common pressure circuit (P) of the hydraulic cylinders (1 through 4) and connected with a control unit which is connected to the switching elements (V1 through V4) of the hydraulic cylinders (1 through 4), and its output signal in relation to time, together with the preset switching sequences of the individual switching elements (V1 through V4), serves to control the end positions of the individual hydraulic cylinders (1 through 4). The control can thus be incorporated in the operating mechanism without expensive separate end position switches at each hydraulic cylinder (1 through 4) or appurtenant actuation element, simplifying the overall design.

Abstract: The invention implements a run-length file format with improved space-sav qualities. The file starts with a header in ASCII format and includes information such as the file format, maximum X and Y values, and a color palette. The binary raster data include at least one byte for each pixel run to indicate the color selected from the color palette and the run length. Concatenation flags demarcate groups of bytes. According to a first embodiment, each run is indicated by a variable-length sequence of bytes with the color in a fixed-length field and the repeat number in a variable-length field. According to a second embodiment, the color and run length are given in separate byte strings, each having a variable length. The file also includes line offset pointers to permit navigation of the file without decompressing it and thus to facilitate operations such as panning and zooming.
