摘要:
An image forming apparatus for obtaining a dye image on an image receiving material by applying an image forming solvent to a heat development photosensitive material and/or the image receiving material comprises: a solvent application device for applying the solvent to the heat development photosensitive material and/or the image receiving material to circulate and reuse the solvent; and a cation exchanger and/or a pollutant adsorbent disposed in the solvent application device so as to come into contact with the solvent. Accordingly, since Ca.sup.2+ ions, Mg.sup.2+ ions, etc., can be removed, the apparatus effectively prevents the fouling of the solvent.

A camera adapted to be loaded with a 35 mm film cassette having a cylindrical body and a tongue portion for defining a film exit slit through which the leader of the film projects, the tongue portion extending substantially tangentially from the side wall of the body. The camera has an openable backlid member and a film chamber member defining a cassette receiving chamber. The cassette receiving chamber is adapted to be opened when the backlid member is opened and comprises a cylindrical portion and a slot portion which substantially conform with the cylindrical body and the tongue portion in shape. Thus the cassette receiving chamber determines the position and orientation of the film cassette when it is inserted thereinto and holds it in place. A guide member extends from the film chamber member to define between the inner surface of the backlid member and itself a film guiding slit aligned with said slot and extending beyond the film aperture of the camera body. The guide member has an inclined surface inclining downward toward the backlid member. When the cassette is inserted into the cassette receiving chamber, the lower edge of the leader abuts against the inclined surface to be stretched and smoothly introduced into the film guiding slit.

A mode change-over device for a mode change-over device for a pre-winding type camera in which, after a loading of a film patrone in the camera and before the shooting, a pre-winding of the film is conducted to fully pre-wind the film on a spool and, when the pre-winding is finished, a mode retaining member is unlocked so as to release a mode change-over member thereby operating a mode change-over switch for a shooting mode, such as to allow an unwinding of the film in a frame-by-frame fashion for each shooting exposure, while the mode change-over member is charged by an opening of a back lid of the camera, the mode change-over device comprising; a counter adapted to operate in response to winding and rewinding of the camera; a retaining member for locking the mode retaining member when the back lid has been opened erroneously or accidentally; and a counter engaging member which prevents the retaining member from locking the mode change-over member when the counter is in the initial position, whereas, when the counter is in the counting position, operates the retaining member for making the retaining member lock the mode change-over member.

A low-molecular weight peptide composition mainly based on dipeptides and tripeptides is produced by dispersing protein raw material from any suitable source in water at a concentration of 5 to 20 w/v %, adjusting the pH of the dispersion to 1 to 4 with an acid, adding at least two acid proteases to the dispersion, and permitting enzymatic proteolysis to take place for a desired period of time at a suitable temperature while supressing the formation of free amino acids. Also provided is a nutrient agent comprising the thus produced low-molecular weight peptide composition mainly based on dipeptides and tripeptides wherein the contents of free amino acids and those peptides having a molecular weight of at least 700 are individually 20% by weight or less. The nutrient agent is useful in medical treatment.
摘要:
An electrophotographic developing apparatus comprises a developing roller and a refreshing roller. The developing roller applies liquid developer to an electrostatic latent image carrier moving in a predetermined direction. The refreshing roller comes into contact with the developing roller and rotates at the same peripheral speed as that of the carrier and in the opposite direction to the moving direction of the carrier. The rotational motion of the refreshing roller causes the developing roller to rotate so as to effect developing the electrostatic latent image on the carrier.
摘要:
Novel lonomycin derivatives, prepared by reacting lonomycin or its salt with an alkali or an alkali metal borohydride, show antibacterial, antiviral and antiprotozoal activity, and have decreased toxicity as compared with lonomycin.
摘要:
A sampling device for a quantitative determination of hydrogen in molten metal, which includes a material in which hydrogen is relatively non-diffusible during testing or readily soluble during sampling and a refractory vessel housing this material. This refractory vessel is sealed so as to maintain a vacuum or negative (reduced) pressure therein, and is provided with a thin-walled aspirating portion which is readily destroyed by an external pressure.

An image-forming process which comprises, upon conducting intensification of images using an intensifier containing at least one intensifying agent selected from the group consisting of peroxides, halogenous acids and cobalt (III) complex compounds, on a color photographic element comprising a support having at least one silver halide emulsion layer in the presence of a reducing agent, adding a mercapto group-free and nitrogen-containing hetero ring compound and a compound represented by the following general formula having a polymerization degree of 1 - 8,000;-- (A).sub.x -- (B).sub.y --wherein A represents ##STR1## or --CH.sub.2 --CH.sub.2 --O--, wherein R represents ##STR2## or --OH, with m being an integer of 3 - 7, R.sub.1 is an alkyl group having 1 to 6 carbon atoms, and R.sub.2 is a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, B represents a monomer unit derived from styrene, methacrylic acid ester, acrylic acid ester, vinyl acetate, acrylonitrile, vinyl alcohol, vinyl chloride, vinyl ether, acrylamide, N,N-dimethylacrylamide, acrylic acid, methacrylic acid, maleic acid, potassium styrenesulfonate, N,N-dialkylaminoalkyl methacrylate, vinyl imidazole or vinyl pyridine, and x and y each represents mol %, with x + y = 100 and x.gtoreq. 30, said intensification being with a processing solution which permits said two compounds to be substantially copresent when forming images through intensification.
摘要:
A silver halide color photographic material comprising a support having thereon at least a silver halide emulsion layer containing a hydrophobic phenolic or naphtholic cyan dye forming coupler together with a 2-(2'-hydroxyphenyl)benzotriazole compound. The color photographic material provides a cyan dye image having improved moisture resistance and high fastness to heat.
