Abstract: When to perform subsidiary exposure before or after main exposure or concurrently therewith with a quantity of light corresponding to about 1/50 to 1/100 of the quantity of light of main exposure, an image forming apparatus according to the present invention can automatically set the standard conditions of subsidiary exposure in response to setting of the standard conditions of main exposure, and can set the optimal conditions of colors and intensity of subsidiary exposure in accordance with the amount of adjustment of gradation. Therefore, even when variations arise in the characteristics and processing conditions of a light-sensitive material or any desired gradation is chosen, natural and fine images can always be formed with no color balance distorted.

Abstract: A method of image recording comprises the steps of performing photometry on a plurality of pixels into which an original film is divided, calculating the large-area transmittance density (LATD) of said original film on the basis of the photometric values for individual pixels, designating the main area of said original film, calculating the average transmittance density of the designated main area on the basis of said photometric values, determining conditions of exposure as appropriate for said original film on the basis of a linear relationship between said LATD and the average transmittance density of the main area, and performing imagewise recording on a light-sensitive material under the thus determined appropriate conditions of exposure. Using this method, even an unskilled operator is capable of reproducing the image of a principal subject such as a human figure or his/her face to provide an optimum density in an easy and precise manner.

Abstract: The improved image forming apparatus with a capability for automatically identifying the type of originals measures the reflected light from an original of interest with at least two sensors for the light of at least one of three primary colors, constructs a discriminant function that makes use of the differences in spectral reflection density between originals and which uses as parameters all the values of measurements obtained or with the higher and lower values being cut off, and automatically identifies the type of the original by discriminating color photographic originals from another type of originals such as color printed originals or black-and-white originals on the basis of the value of said discriminant function. The image forming apparatus may measure the reflected light from the original with sensors for the light of three primary colors and identify a low-density, low-constant original by means of a predetermined discriminant formula.

Abstract: The improved color image forming apparatus is so designed that the image forming condition computing means having a learning capability, such as a neural network having a back propagation learning algorithm, is caused to learn preliminarily those image forming conditions which are appropriate for the specific type of a documents (e.g. a reflection-type original or a transmission-type original such as a negative film or a reversal film) or the original image carried on the documents such as sea, mountains or a snow scene, examples of such image forming conditions being exposing conditions (e.g. the balance of three primary colors and their densities) and the conditions of developing, fixing and otherwise processing light-sensitive materials, and image is formed on a particular light-sensitive material under the image forming conditions computed by the computing means which has learned said appropriate conditions.

Abstract: A method of picture recording in which a surface of a photosensitive material is exposed to light containing a picture image and the exposed surface of the photosensitive material is superposed on an image receiving surface of an image receiving material so as to transfer the picture image obtained on the exposed surface of the photosensitive material onto the image receiving surface of the image receiving material. Judgment is then made as to whether the surface of the image receiving material to be superposed on the photosensitive material is the image receiving surface by using a detection device for detecting an absorption or reflection factor for light of a wavelength peculiar to the image receiving surface before the photosensitive material is superposed on the image receiving material, so that feeding of the image receiving material may be stopped when the judgment proves that the detected surface is not the image receiving surface.

Abstract: A piping travelling apparatus having a plurality of continuous treads driven by motors through transmission gearing. The continuous treads are mounted to a frame and spaced apart a predetermined distance peripherally of the inner wall surface of the piping. At least one of the continuous treads is kept in contact with the inner wall surface of the piping no matter what the posture of the apparatus may be, so that the apparatus can travel without any trouble even if its posture undergoes a change when it moves along elevations and depressions on the inner wall surface of the piping or negotiates the boundary between different levels of the inner wall surface or bends of the piping. The apparatus enables a travel through piping of relatively small diameter having vertical or steeply slanted pipes to be made without any trouble.

Abstract: Sludge deposit is stored in a sludge deposit receiving hopper, and the stored sludge deposit is fed onto a belt conveyor and transferred to a mixer. A hardener is fed to this mixer from a hardener hopper. A conveyor belt is disposed on the belt conveyor to measure the quantity of the sludge deposit transferred by the belt conveyor. According to this measured value of the transferred sludge deposit, the quantity of the sludge deposit fed from the sludge deposit receiving hopper and the quantity of the hardener fed from the hardener hopper are controlled. The sludge deposit is mixed and kneaded with the hardener, and the sludge deposit is solidified.
