摘要:
An automatic image developing apparatus for a halide silver photographic photosensitive material includes a developing tank, a fixing tank, and a washing tank for successively delivering therethrough the halide silver photographic photosensitive material which has been exposed or has recorded an image thereon. The washing tank is supplied with washing water at a rate of 2 liters or less per 1 m.sup.2 of the photographic photosensitive material. The apparatus also has a plurality of roller pairs for squeezing water from the photographic photosensitive material fed from the washing water toward a drying unit, and a roller washing unit associated with at least a first one of the roller pairs which is closest to the washing tank to grip the photographic photosensitive material from the washing tank, for washing said at least one roller pair at all times.

A method for bleaching silver halide color photographic materials is described using a bleach solution containing an organic acid metal complex salt and hydrogen peroxide or a compound releasing hydrogen peroxide, wherein the bleaching activity of the bleach solution can be effectively maintained for a long period of time by supplying thereto a replenisher composed separately of a composition containing hydrogen peroxide or a compound releasing hydrogen peroxide and a composition containing an organic acid metal complex salt, which are separately stored and added as a mixture thereof or separately to the bleach solution when the activity thereof is weakened during processing or during storage of the bleach solution.
摘要:
An automatic film winding device for camera comprising the film winding member of which the outer peripheral portion at one end is formed larger in diameter than the other outer peripheral portion. The automatic film winding device for camera comprises a pressing means mounted on a camera body for pressing the narrowed leading end of the film against the outer peripheral surface of the film winding member at the position where the leading end of the film is received into the film winding chamber. The pressing means is so set that its pressing position corresponds to a part of the cut edge of the narrowed leading end portion of the film, and mounted on the inner surface of a back cover and urged by spring means so as to be capable of pressing the leading end of the film to the film winding member in the winding operation.

The present invention relates to a method of removing mercury-containing contaminations in gases by passing the gas to be purified through a filter bed which is devised to make the gas contact effectively. The method is characterized in that, the filter bed is consisted of specific material prepared by binding onto a carrier substance such as granulated pumice, with sulfurous substance as contamination absorbing agent, such as natural sulfide minerals subjected to a surface activation pretreatment, synthetized metal sulfides and sulfur.According to the present invention, it is intended to remove contaminations in gases, especially those containing vaporized mercury together with adsorption on the filter bed material, in such a mechanism that mercury, which has a high vapor pressure, is converted into its sulfide, which shows very low vapor pressure, by contacting the gas with sulfides of other metals or with sulfur.The present invention relates to a method of removal of metals and their compounds, especially of mercury and its compounds, contained in gases.
摘要:
A pattern information memory, provided with a font memory having a total bit capacity of n.A and comprising a number A of circulating memories each having a rewritable n-bit capacity, each bit being capable of storing one dot obtained by dot decomposition from each unit pattern. A minimum unit of designated addresses in the font memory is switched in accordance with a value of a number m (m = 1, 2, 3, . . . less than the number A) to provide a memory capacity of (n.sup.. A)/(n.sup.. m) patterns in combination of a number m of said circulating memories per each pattern of n.sup.. m dots. Writing and reading-out are performed by making once access to a number m of said circulating memories within a unit access time for one bit in a case : m=1. Accordingly, the writing and the reading-out for each pattern information are performed in a constant period of time irrespective of the value of the number m.

A color photographic material having differently sensitized silver halide emulsion layers including a silver halide emulsion layer containing a 3-anilino-5-pyrazolone magenta dye-forming coupler, the coupler having a halogen atom or an alkoxyl group at the 2-position of the anilino group and an aliphatic acylamino group at the 5-position of the anilino group.
摘要:
A color photographic material having at least one silver halide emulsion layer containing a 3-anilino-5-pyrazolone type magenta dye forming coupler and a phenolic compound for improving the light fastness of the magenta dye formed by the coupling reaction of the magenta dye forming coupler with the oxidation product of a color developing agent in combination with a nucleus-substituted hydroquinone, in which the reduction of the coupling reactivity of the magenta dye forming coupler during the storage of the color photographic material caused by the presence of the phenolic compound is prevented efficiently.

Provided is a bonding material which can bond base materials or substrates having different linear thermal expansion coefficients, and can have heat resistance against temperatures of 300° C. or higher, vacuum airtightness and bonding strength, further which has excellent handleability and workability. The bonding material is produced by mixing, in a content ratio of 0.01 to 60 mass % (to the whole), a metal Ga, and/or at least one metal or alloy powder selected from the group consisting of a metal powder mixture of a combination of Bi and Sn or an alloy powder thereof, and a metal powder mixture of a combination of Bi, Sn and Mg or an alloy powder thereof with a Bi2O3-based glass frit powder having an average particle diameter of 200 μm or less. The bonding material may be formed in a paste form by adding a solvent thereto. This feature makes it possible to bond together substrates having different thermal expansion coefficients without causing a crack or unsticking.
