Abstract: A method for performing image processing is embodied in apparatus (10) that includes a classification circuit (86). The classification circuit (86) classifies each pixel (26) in an image partly on the basis of a comparison between (A) the variation among pixel values in a window (28) containing that pixel (26) and (B) an activity-level threshold (PREV_MD) determined by a routine (Figure 4) that computes that threshold from other pixel values in the image. On the basis of this classification, a multiplexer (82) selects among the outputs of a low-pass circuit (70) and a high-pass circuit (74, 76, 78, and 80) to produce a replacement pixel value for the raw pixel value that a scanner (20) produces by scanning an image source (16).

Abstract: To measure a distance between two running vehicle, a measurement signal (S1) is first generated by irradiating light beam toward an article to be measured and then receiving the reflected light beam from the article. An apparatus for determining the forgoing distance therebetween using light wave operates such that a reference signal (S2) and the measurement signal (S1) generated in that way are input a digital mix-down circuit (1) composed of two-stage flip-flop circuits (U1,U2) to determine a phase difference between the reference signal (S2) and the measurement. The apparatus includes as essential components a clock delay circuit (10) for delaying the going-high edge of the measurement signal (S1) while the reference signal (S2) is going high at an output terminal of a flip-flop circuit (U1) on the input side of the digital mix-down circuit (1) and a data delay circuit (20) for delaying the going-down edge of the reference signal input into a data terminal of the flip-flop circuit (U1). Usually, the clock delay circuit (10) is electrically connected to the digital mix-down circuit (1) via the data delay circuit (20), while the data delay circuit (20) is electrically connected directly to the digital mix-down circuit (1). Alternatively, both the clock delay circuit (10) and the data delay circuit (20) may electrically be connected directly to the digital mix-down circuit (1).

Abstract: A magneto-optical recording medium has a recording layer whereon information is magneto-optically recorded. A readout layer is provided on the recording layer. The readout layer has a compensating temperature that is located between room temperature and the Curie temperature. In the readout layer, upon an application of a light beam, the in-plane magnetization occurs at room temperature and a transition from the in-plane magnetization to vertical magnetization occurs as the temperature of the irradiated area of the readout layer rises above a predetermined temperature. By employing this magneto-optical recording medium, with an application of a light beam that is intensity modulated into two levels, only a spot having a temperature not less than a predetermined temperature is involved in the reproduction; therefore, a recorded bit with a size smaller than the diameter of the light beam can be reproduced, thereby greatly increasing the recording density. Further, the level of the reproduced signals is increased, and crosstalk from the adjoining tracks is reduced; thus, information recording and overwriting can be conducted more easily.

A second insulating film pattern having a width larger than that of the trench is formed on the trench and a peripheral portion of the trench. The second insulating film pattern prevents out-diffusion phosphorus and boron in the silicon oxide film. The first insulating film which is not covered with the second insulating film pattern is removed to form a first insulating film pattern. The surface of the semiconductor substrate which is not covered with the first and second insulating film patterns is thermally oxidized.

Abstract: A process, compatible with bipolar and CMOS silicon device manufacturing for fabricating complementary buried doped regions in a silicon substrate. An N+ doped region (12) is formed in the silicon substrate by known methods of arsenic doping and drive in. This is followed by depositing a first thin epitaxial silicon cap layer (14), under conditions of minimum N+ autodoping. Part thickness of this first epilayer is converted to oxide (18), and the oxide is patterned to provide apertures in an area where it is desired to form a P+ region. A P source material (20) is deposited and a drive-in anneal is used to dope the silicon with P in the areas of the oxide aperture opening. Subsequent to drive in, the dopant source layer and the oxide mask is removed by wet etching. An oxide is regrown on the surface, including the P+ region (22) and subsequently, the oxide layer is stripped in dilute hydrofluoric acid. Next, a second epitaxial silicon layer (28) is deposited to make up the total epi thickness to a desired value, using process conditions of minimum P doping.

Abstract: The block (3) has a flat section (5) to receive the nails (6) by means of which the covering boards (1) and bases (2) of the pallet are connected to said block. Projecting from the region of the flat section (5) are webs (25, 26) which end integrally in each case in a transverse plate (31, 33). Further flat sections (7, 8, 9, 10) are thus formed, which only serve to transmit compression forces, but not connection forces between the block (3) and covering boards (1), bases (2) or bottom boards (4). The webs (25, 26) surround openings (22) and cutouts (23, 24) which bring about a weight reduction of the block (3). Since the block (3) is injection moulded, the outer surfaces of the transverse plates (31, 33) can be printed on. <IMAGE>
