Abstract: There is provided a copper-based sliding alloy excellent in wear resistance and anti-seizure property. A phase of 2 to 30 wt. % lead is dispersed in the copper alloy. This lead phase contains 0.1 to 6 vol. % hard particles such as SiC, SiO2, Si3N4, Al2O3, TiC, WC and TiN having an average particle size of 5 to 25 &mgr;m. Because hard particles are included in the lead phase, wear resistance is excellent and anti-seizure property is improved. The lead phase, which is soft, serves as a cushion and the attack on a mating member by hard particles is reduced. Further, the falling-off of lead is minimized because the lead phase also includes the hard particles.

Abstract: A light-sensitive material processing apparatus comprises a circulating path through which processing solution in a processing tank is circulated; a pump for circulating the processing solution through the circulating path; and an oxidation promoting section provided to at least one of a part of the processing tank and a part of the circulating path, the oxidation promoting section having a depth shallower than that of the processing tank and a upper portion open to atmosphere, wherein a flow speed of the processing solution at the oxidation promoting section is not slower than 1.times.10.sup.3 mm/min.

Abstract: A photosensitive material processing apparatus includes plural processing tanks each to process a photosensitive material; plural cartridges each to fill solid processing agents for replenishment used in each of the plural processing tanks.

Abstract: A photosensitive material processing apparatus for processing a photosensitive material such as a photographic film and a photographic print in use with a solid processing agent. The apparatus includes: a processing tank for processing the photosensitive material; a processing agent accommodating chamber for accommodating the solid processing agent; a pump for circulating a processing solution between the processing tank and the processing agent accommodating chamber; and a processing agent supply for supplying the solid processing agent to the processing agent accommodating chamber. The processing agent accommodating chamber includes a processing agent dissolving member which further includes a processing agent support member for supporting the solid processing agent. A sectional area of the processing agent support member is increased as it comes to a lower portion of the processing agent supporting member.

Abstract: An image recording machine has a plurality of light sources capable of emitting light independently for exposing a part of a photographic film without causing double exposure and with a printing controller. At least one of the light sources is caused to flash continuously for printing codes for timing during film transport, other light sources are caused to flash in synchronization with flashing of the light source for printing codes for photographing information, and the light source for printing the codes for photographing information is caused to flash for printing reference codes which are to be the judgment standards for the codes for photographing information.

Abstract: A processing machine to process information recorded on a photographic film to be processed in the form of plural information. When information contents relating to the same processing item are recorded both in the form of information that is possible to rewrite and in the form of information that is impossible to rewrite, the photographic film is processed based on the form of information that is possible to rewrite.

Abstract: An apparatus for forming a latent image of an identification data in an edge portion of a new photosensitive film is disclosed here. The apparatus comprises editing unit to edit the identification data and an exposure position data, a memory to store the edited data, a register for registering an identification data from the memory and exposing unit to form a latent image of the registered identification data on the photosensitive film based on the exposure position data and synchronized with the feeding of the photosensitive film.

Abstract: An automatically controlled film packaging system which is capable of exposing necessary data as a latent image onto the edges of pre-used film according to the input signal of a unit length required for the merchandise cutting the film into the unit length and taking the film up on a selected patrone, comprising a center processing unit which controls the system automatically when the unit length required is shifted, without any manual re-setting but only by inputting a new unit length of the film required for the merchandise to be produced.

Abstract: The invention provides an apparatus for optically writing a data onto a non-exposed film being coated with photosensive material while moving the film to a predetermined direction. The data represents a film frame No., photosensitive emulsion lot No. and so on. The apparatus has two groups of LEDs being arranged with a pitch in parallel two lines being crossing at right angles to a film proceeding direction. The disposing position of LEDs on the one line differs by half of the pitch from that on another line. Therefore, the center of light spot on the one of spotted parallel line irradiated on the film does not face with that on another spotted line along the film proceeding direction. Further, the emission timings of the two groups of light emission sources are respectively controlled to have some time lag therebetween, thereby superposing partially the parallel two spotted lines.
