A color image reading apparatus comprises: first to N.sup.th (color line image) sensors for receiving respective color images from the projected image and respectively generating first to N.sup.th (color) signals, the first to N.sup.th sensors respectively extending in a main scanning direction and being arranged in a sub-scanning direction SD in order from the first to N.sup.th sensors with different pitches between the first to (N-1).sup.th sensors and the N.sup.th sensor; a receiving circuit for receiving an enlargement ratio and for supplying a scanning pitch according to the enlargement ratio; a scanning unit responsive to the scanning pitch for scanning the image against the first to N.sup.th sensors in the SD at the scanning pitch in the order, wherein lines of the first to (N-1).sup.th sensors deviate from the lines of the N.sup.th sensor according to the enlargement ratio; and a line combining portion for selecting one of lines of each of the first to (N-1).sup.th signals closest to the present line of the N.sup.th signal, combining the selected one of lines each of the first to (N-1).sup.th signals with the present line of the N.sup.th signal, and for outputting the combined color signals.A secondly closest line may be determined and selected through a random operation or a weighted operation. The corresponding method of reading a color image is also disclosed.

A color cathode ray tube includes an evacuated envelope having a generally rectangular panel portion, a narrow neck portion having a circular cross-section and a funnel portion tapering down from a panel-portion side thereof toward a neck-portion side thereof for connecting the panel portion and the neck portion, a three-color phosphor screen formed on an inner surface of the panel portion, an electron gun housed in the neck portion, and an internal conductive film extending from an inner wall of the neck portion to an inner wall of the funnel portion. The funnel portion is provided with a yoke-mounting portion of generally truncated quadrilateral-pyramidal shape for mounting a beam deflection yoke therearound on the neck-portion side of the funnel portion. The internal conductive film is formed of a first part and a second part, the first part is formed of graphite, metallic oxide and potassium silicate, and the second part is formed of graphite and potassium silicate. The first part extends from the neck portion in the vicinity of a forward end of the electron gun to a position in the yoke-mounting portion spaced a distance in a range of 60 mm to 150 mm from a splice line between the neck portion and the funnel portion, and the second part overlaps with the first part at opposing ends thereof and extends to a vicinity of a seal line between the funnel portion and the panel portion.

An achromatic color judging region is determined in a red-green-blue (RGB) color system, and it is judged in an achromatic color judging unit whether or not a color picture at a remarked pixel designated by a R multi-valued digital input signal, a G multi-valued digital input signal and a B multi-valued digital input signal is placed within the achromatic color judging region. Also, the RGB multi-valued digital input signals are converted into pieces of RGB binary data in an error dispersion processing unit while dispersing errors occurring in the RGB binary data. In case where it is judged that the color picture is an achromatic color because the color picture is placed within the achromatic color judging region, a piece of achromatic color data is generated from the RGB binary data in an achromatic color reproducing and color transforming unit and is output to reproduce the color picture at the remarked pixel. In contrast, in case where it is judged that the color picture is a chromatic color because the color picture is not placed within the achromatic color judging region, the RGB binary data are output to reproduce the color picture at the remarked pixel. Therefore, the color picture can be reproduced in a smoothly changed gradation in a small sized color picture processing apparatus.
摘要:
A high volume workpiece treating system includes horizontally arranged treating staions, including vertically arranged treating stations. A conveyor system moves workpieces sequentially and cyclically through the vertically arranged treating stations so that, while one treating station is loaded with workpieces and carrying out a treating procedure, the next station in the vertical group is being loaded with the next batch of workpieces. A single conveyor is arranged to supply a group of vertical treating stations with workpieces and to remove the workpieces from each station at the completion of the treating process. The conveyor and treating stations are arranged to handle sequential batches of workpieces with a minimum of idle time to achieve maximum efficiency. Each group of vertical treating stations is associated with a single piece of auxiliary equipment that controls the flow of treating solution through each of the treating cells of the group. A workpiece handling procedure governs movement of the conveyor and opening and closing of the treating stations in a continuous process.

An apparatus and process for chemically treating a surface of a workpiece with a liquid solution that produces an environmentally harmful gaseous byproduct includes a water spray system for contacting and reacting the gaseous byproduct at the location where it is produced during the chemical treating process. The reacted byproduct is then carried away in the water stream and with the chemical treating solution for safe disposal and recovery. Residual unreacted gaseous byproduct is chemically treated at a separate location within the same apparatus layout used to process the workpiece.
摘要:
The present invention can be applied to an operation input processing apparatus provided with an operation input executing section which issue tickets in response to users' input operations. A personal computer extracts an application program applied for the operation input processing apparatus from a software resource containing a plurality of application programs and operates the operation input executing section by executing the extracted application program. Thereby the operation input processing apparatus having various functions can operate application programs easily without damage thereto.
