摘要:
A method for processing photosensitive materials in which photosensitive materials are conveyed along a serial conveyance passage while guiding the photosensitive materials on both sides thereof by using pairs of guide members to successively perform development processing steps comprises the steps of dividing the conveyance passage into a plurality of blocks, a spacing distance between the pair of guide members on the conveyance passage being changeable in each of the divided blocks, and changing the spacing distance between the pair of guide members in each of the blocks, when a photosensitive material having a different widthwise dimension is introduced into the conveyance passage, in accordance with the widthwise dimension of the photosensitive material before introducing a forward end of the photosensitive material having the different widthwise dimension into each of the blocks. Therefore, when photosensitive materials having different widthwise dimensions are alternately processed, it is possible to start processing for a following photosensitive material during a period in which a preceding photosensitive material is processed on the conveyance passage.

Disclosed is a method for stabilizing a crude oxy-methylene copolymer having thermally unstable terminal groups, which comprises subjecting a crude oxymethylene copolymer to heat treatment in the presence of at least one quaternary ammonium compound represented by the following formula (1): [R1R2R3R4N+]nX−n (1) wherein each of R1, R2, R3 and R4 independently represents an unsubstituted or substituted alkyl group, an aryl group, an aralkyl group which is an unsubstituted or substituted alkyl group substituted with at least one aryl group, or an alkylaryl group which is an aryl group substituted with at least one unsubstituted or substituted alkyl group; n is an integer of from 1 to 3; and X is a hydroxyl group or an acid residue. In this method, even by the addition of a very small amount of the quaternary ammonium compound, the decomposition rate of the unstable terminal groups can be remarkably increased, thereby facilitating the stabilization of the crude copolymer. Therefore, by this method, it has become possible to easily produce an excellent oxymethylene copolymer within a short period of time, which has substantially no unstable terminal groups and, therefore, has excellent thermal stability and color tone.
摘要:
A multi-layer sliding bearing having an excellent anti-fretting property, comprises a back steel layer, and a bearing alloy layer formed on the back steel layer. A film of phosphate having a thickness of 0.1-15 .mu.m is formed on a back surface of the back steel layer, thereby enhancing the anti-fretting property of the bearing. The provision of the phosphate film well compatible with a mating material overcomes damage to the bearing due to fretting in a high-speed range. Therefore, the bearing can fully exhibit a bearing performance even under severe conditions of use in a high-speed, high-temperature and high-load range as typically experienced in a high-performance engine.

An automatic photofinishing apparatus has a film processing section, which processes exposed photographic film, and includes a train of processing baths. The film is passed successively through processing solutions respectively within the processing baths. A printer section, downstream from the film processing section, prints an imaging frame of the film to photographic paper immediately after processing of the film. A paper processing section processes the paper after printing, and includes a train of processing baths. The paper is passed successively through processing solutions respectively within the processing baths, so as to produce photographic prints. A film path member is disposed between the film processing section and the printer section, and constructed to twist the film during an exit from the film processing section in accordance with a direction of the film processing section relative to the paper processing section, and to bring the film in parallel with the paper in the printer section.
