Abstract: A method and apparatus for converting polar format radar video data into a horizontal raster format output for compatibility with a TV monitor. Radar video data comprises radar video pixels each having an associated intensity value and a polar coordinate in a raster display. The TV monitor includes a display screen wherein each pixel has a corresponding X,Y address. The apparatus and method of the invention comprises steps or apparatus for storing (160) the radar video pixels using polar coordinates translating (120) X,Y addresses into corresponding polar coordinates, scanning the storage means using the translated X,Y address and interpolating a radar intensity value for the translated X,Y address. The scanning process includes accessing at least four radar video pixels surrounding the translated X,Y address. In the preferred embodiment of the invention, the scan conversion of the X,Y addresses is accomplished in a seven stage scan converter pipeline.

Abstract: A solid state imaging device with a plurality of line sensors (3, 4, 5, 6) in which each line sensor receives the light through the divided light paths from a straight line of a document into each unit is disclosed. The divided light paths are obtained by bending each rod lens (8) of a rod lens array (2), providing concave or convex lenses or convex mirrors or by providing transparent plates at different angles. As a result of the dividing of light path, the line sensors pick up linear image data without abutting each sensor in a straight line.

IPC: H01L27/04

Abstract: A semiconductor varactor, such as a thin film poly-Si varactor, has larger effective gate areas in accumulation than in depletion, together with a capacitive switching ratio which is essentially determined by the ratio of its effective gate area in accumulation to its effective gate area in depletion. To that end, such a varactor has a fully depletable active semiconductor layer (42), such as a thin poly-Si film, and is constructed so that at least a part of its active layer is sandwiched between a relatively thin dielectric layer (44) and a relatively thick dielectric layer (43). The thin dielectric layer (44), in turn, is sandwiched between the active semiconductor layer (42) and a gate electrode (46). Furthermore, one or more ground electrodes (45) are electrically coupled to laterally offset portions of the active semiconductor layer (42) in partial overlapping alignment with the gate electrode. In keeping with this invention, the capacitance per unit surface area of the thin dielectric layer (44) is so much greater than the capacitance per unit surface area of the thick dielectric layer (43) that the series capacitance of the depleted active semiconductor layer (42) and the thick dielectric layer (43) negligibly contribute to the capacitance of the varactor when it is operating in its depletion mode.

Abstract: The invention relates to a process for visually monitoring the formation of web-shaped, transparent material moving relative to the device, having a device which comprises a light source (5) on one side of the web (1), with which a light flux of desired colour and intensity which penetrates the web is generated, and a camera (10) on the side of the web opposite the light source, which intercepts the light flux penetrating the web and converts it into a video signal which can be fed to a video monitor unit with a display screen. 
<??>Especially for the purpose of examining paper and cardboard for photographic purposes, the light source (5) transmits the light flux in each case as a flash of light with an exposure time t1 that is to be dimensioned so short that during the exposure time the feed of the web (1) is below the limit which renders the image unsharp in terms of motion, that the image is intercepted by the camera (10), and that a visible image to which a comparative image is visually assigned is generated on the display screen of the video monitor unit.

Abstract: A shoe at least provided with a sole with foot surface and an upper shoe with counter extending above the foot surface and connected to an edge of the sole and an edge party closing above the instep and the heel of the foot and bounding the instep opening of the shoe. When a shoe fits, between the toes and front part, a free space of 11 to 15 mm is free, because the leading edge of the toes slides forward in the shoe during bending movement of the foot. In children's shoes a part of this space is used for absorbing the growth of the foot. During growth the ball of the foot moves forward and no longer lies precisely on the deepest point of the shoe. The invention proposes a shoe in which the edge part of the instep opening supported by the counter, at least on the heel side, is provided with removable filler means to reduce the instep opening, this such that the rear portion of the edge part of the instep opening is displaced relative to the sole in the direction of the front part of the shoe. During growth the ball line remains at the same position relative to the foot bed and the foot can grow two-thirds rearward and one-third forward if during growth the filler means along the edge part are removed. The foot hereby remains optimally supported by the shoe.

Abstract: An opening (31) for discharging toner is formed in a lower part of a cartridge body (4) containing toner. A shutter mounting body (34) is mounted on the opening (31). A first shutter (1) is slidably mounted on the shutter mounting body (34). A second shutter (2) is slidably mounted on the first shutter (1). A front end of a sealing member (3) for sealing the opening (31) is extended, the extended front end being inserted through a seal traction opening (52) formed in a front end of the second shutter (2), and fixed to a front end of the first shutter(1). When the second shutter (2) is pulled out of the shutter mounting body (34), the sealing member (3) is towed by the seal traction opening (52). In addition, the first shutter (1) is further towed by the sealing member (3), to be also pulled out. Consequently, nearly half of the sealing member (3) from its front end is stripped. When the second shutter (2) is further pulled out after the movement of the first shutter (1) is regulated, the seal traction opening (52) in the second shutter (2) tows the sealing member (3) while allowing the insertion of the sealing member (3). At this time, the sealing member (3) is stripped while being so folded that a toner adhering surface is located in its inside. In this construction, the stroke for stripping is decreased, thereby to make it possible to prevent contamination by toner as well as prevent a large part of the sealing member (3) from being ineffective.
