Abstract: The invention relates to a plastic transparency having improved resistance to cracking. Plastic transparencies have been used as airplane windows, but have been subject to cracking, especially when subjected to a high humidity environment. The disclosed plastic transparency includes a transparent sheet member and a thin resinous coating overlying the peripheral edge surface of the sheet member. The sheet member is formed of a multi-axially oriented plastic material that is absorptive of moisture, preferably polymethyl methacrylate. The edge coating has a moisture permeation rate substantially less than that of the underlying sheet member, so when the window is exposed to an environment of high or variable humidity, any moisture gradient adjacent the peripheral edge surface is reduced, and the resultant tensile stress and incidence of cracking in the window are correspondingly reduced.

Abstract: The invention relates to an information transmission system with a transmission in both directions of transmission, in each case at a different frequency. According to the invention, the transmitting sections (1, 13) and the receiving sections (4, 17) of both terminal stations (I, II) are connected via optical branching elements (8, 10) to a single optical fibre (9) as transmission medium. Optical transfers between the branching connections of the optical branching elements (8, 10) are eliminated by a filter (5, 16) in the adjoining receiving path. Carrier-frequency systems Z12 or Z60, for example, can be used as transmitting sections (1, 13) and receiving sections (4, 17) (Figure 1). Intermediate stations (III) can be correspondingly equipped with optical branching elements (18, 23) and filters (19, 22) (Figure 2). The system according to the invention is particularly suitable for electricity supply companies since a cable with optical fibres can be run directly next to power supply lines without being influenced by interference voltages and, at the same time, the familiar carrier-frequency systems can be used. <IMAGE>

Abstract: An apparatus for monitoring toner concentration on a photoreceptor surface. The apparatus includes a light emitting diode (90) a phototransistor (92), a beam splitter (94), and a lens (96) disposed between the beam splitter (94) and the photoreceptor surface (12) to collimate the light beam between the lens and the photoreceptor surface. A portion of the light emitted from the LED is transmitted throught the beam splitter and the lens to the photoreceptor surface. Collimated light is reflected from the photoreceptor surface back through the lens and reflected from the beam splitter to the phototransistor. The output signal from the phototransistor because of the incident and reflected collimated light is independent of the distance of the lens (96) from the photoreceptor surface (12). A second lens may be disposed between the beam splitter and the phototransistor to enhance overall resolution.

Abstract: The present invention relates to a color imaging device which suppresses false color signals appearing in an area where the difference of brightnesses is great in the horizontal or vertical direction.When the correlation between picture elements adjacent in the vertical direction is little and the false signal appears in a boundary part in the vertical direction, the false signal is detected, whereupon a color signal is demodulated by utilizing the correlation between the signals of picture elements in the horizontal direction. On the other hand, when the correlation between picture elements adjacent in the horizonta( direction is little and the false signal appears in a boundary part in the horizontal direction, the false signal is detected, whereupon a color signal is demodulated by utilizing the correlation between the signals of picture clements in the vertical direction.As a result, the moire phenomenon attributed to the false color signals can be conspicuously reduced.While embodiments of the present invention refer to color imaging devices which employ MOS type solid-state imaging devices, the invention is also applicable to an imaging device which employs CCDs and color image pickup tube which separates colors by means of a mosaic color filter.
