Abstract: The resolution of an array sensor can be increased by projecting images of picture elements, which lie on the same scanning line, on a plurality of one-dimensional array sensors composed of a number of photoelectric transducers arranged with an equal interval in a row; and then subjecting picture signals, which have been output respectively from the array sensors, to a combination processing so as to obtain continuous picture signals. It is possible, without using any memory unit, to output picture signals with a resolution higher than that available from the use of a single one-dimensional array sensor, namely, with a resolution proportional to the number of a plurality of one-dimensional array sensors.

Abstract: A desired picture or pattern such as a wiring pattern may be recorded on a recording surface bearing a photosensitive material coated thereon by sweeping a light beam obtained from a light beam source and then scanning, with the thus-swept light beam, the recording surface. Sweep position pulse signals are obtained by branching out the thus-swept light beam and detecting same with a photosensor. The light beam output from the light beam source is modulated in accordance with the sweep position pulse signals. The levels of the sweep position pulse signals are changed to a predetermined constant level in accordance with the types of their corresponding picture signals, in other words, the sweep position pulse signals are attenuated where they correspond to picture-bearing portions of the picture or pattern or are amplified where they correspond to picture-free portions of the picture or pattern, so that the synchronization between the sweeping speed and the picture signal reading-out speed is ensured.

Abstract: A method for scanning and recording a plurality of original pictures by a picture reproducing machine in which desired parts of said plurality of original pictures of different reproduction magnification are simultaneously input and scanned, and at least parts of the desired portions are stored into memory so that they may be output, scanned and recorded simultaneously with different magnifications.

Abstract: Graphic signals and literal (or drawing) signals are recorded substantially simultaneously by increasing or decreasing the number of beam components output from at least one of a literal head and a graphic head after a specified number of scanning lines, both of which heads are being synchronously fed in the sub-scanning direction. Variation of the number of beam components used in the head is used to change the scan length of the head, for synchronizing the feed pitch therefor with the feed pitch of the other head when the scan lengths of the two are not integrally related. Differences between the feed pitch and the scan length of the variable scan length recording head are corrected by slight adjustments of the head position in the sub-scanning direction.

Abstract: In continuous hot dipping of metal strip, the tension of the strip at pre-treatment furnaces and that at air-wiping nozzles are isolated and made independent of each other. For this purpose bridle rolls driven by motors are disposed downstream of the pre-treatment furnaces. The tension at the former is maintained at a lower value, while the tension at the latter is maintained at a higher value. The bridle rolls are mounted in bearings which are covered by seal boxes in which an inert gas is enclosed so as to prevent the intrusion of atmospheric air into the furnaces.

Abstract: A method and machine for positioning films on base sheets are disclosed. A first film on a base sheet is laid out into a desired position on a base plate, and positions of edges of a picture pattern on the first film are detected by photoelectric detectors including photoelectric elements which detect the edges and output signals whose strengths are varied depending on the positions of the elements with respect to the edges. Then, a second film on a base sheet is put on the first film so that edges of a picture pattern of the same shape as in the first film, on the second film may approximately overlap to those of the first film, and the edges in the second film are completely coincided with those in the first film by moving the second film by means of a drive means according to the output signals from the elements, thereby positioning the second film into the desired position.

Abstract: A method and machine for trying on a hair form in image, in which a hair pattern portion is deleted from a face shape to be fitted by a hair pattern, and the face shape with the hair pattern thereon is displayed. In the machine, the hair pattern and the face shape with a mask for masking the hair pattern portion on it are arranged optically in symmetrical positions with respect to a half-mirror, and the face shape with the hair pattern thereon is taken through the half-mirror by a video camera. In the method, the hair pattern and the face shape are taken by the camera to obtain first and second signals by which the face shape with the hair pattern thereon is formed and then is displayed.

Abstract: A positioning device is disclosed, designed for use in the color separation plate making industry, whereby several sets of original films may be mounted on base sheets, each member of a set being mounted on a different base sheet in the same position relative to the members of the other sets. The invention employs a rotating frame which has several faces on which base sheets are mounted, and incorporates a positioning device adapted to locate original films accurately at corresponding positions on the different faces. Thus the invention achieves its desired result accurately, conveniently, and cheaply.

Abstract: A photosensitive material for making a color separation record is imaged through a color separation filter. An electroluminescent panel having an image reversal property is then placed on the material. The panel is imaged through a color correction filter and radiates a negative color removal image onto the material.

Abstract: A photosensitive material such as photographic film is exposed with a color image through a color separation filter. An electroluminescent plate is placed over the film and exposed with the color image first through the color separation filter with the plate charged to one electrical polarity and again through a color and contrast compensating filter with the plate charged to the opposite polarity. A high electrical potential is applied to the electroluminescent plate causing the plate to radiate a luminescent image onto the film as a color and contrast compensation exposure.
