Abstract: A piece negative feeding apparatus for successively feeding piece negatives to an exposing section. The apparatus includes a piece negative storage 10 for storing piece negatives 2 in a plurality of orders, as divided into the orders each consisting of at least one piece negative, a negative transport mechanism 20 for transporting the piece negatives from the piece negative storage 10 to the exposing section 8, and an order demarcation recognizing device 7a for recognizing demarcations between the orders based on order identifiers 3 storable in the piece negative storage 10 and transportable by the negative transport mechanism 20.

Abstract: A photographic printing apparatus is provided in which a plurality of film cartridges X stored in a cartridge storage 1 are unloaded and transferred one by one to a film table 5 and after reading image data from a film of the cartridge with a scanner module 6 using light from a light source module 4, and printing it on a photosensitive material PC placed on an exposure bed 3c by exposure of light through a lens unit 4b, returned back to the cartridge storage 1.

Abstract: A film loading and unloading mechanism sends out a film from a cartridge in which a film with a magnetic recording portion is contained and rewinds the film. A magnetic information reading and writing mechanism reads information recorded in the magnetic recording portion of the film and may write change information in the magnetic recording portion. An image reading mechanism reads image information recorded in the film. An output device outputs both types of information. The magnetic data recorded on a film with a magnetic recording portion is read, and displayed on the monitor screen, allowing bit error and damage of magnetic data to be checked.

Abstract: Both a web of film and film in a cartridge can be selectively processed for printing. A rotary table is provided on a common base with a scanner assembly and a printing/exposure unit provided on opposite sides of the rotary table in an opposed manner. A web of film is fed on film guides to pass the scanner assembly, rotary table and printing/exposure assembly in a straight manner. A film in cartridge is fed through a cartridge feed portion onto the rotary table.

Abstract: A photographic printing apparatus can process any of a roll of films, a strip of film and a film in a cartridge. A feed speed adjusting unit is provided between a scanner unit and a printing/exposure unit. A cartridge supply unit is provided upstream of the scanner unit and upstream of the printing/exposure unit. A strip of film is fed by a film carrier and a cartridge film is fed by a feed roller of a cartridge holder.

Abstract: A carrier device can receive cartridges each containing a film from a lateral direction and send them reliably, efficiently and continuously to a photoprinting machine in a straight line, while holding them in position with an arm. Cartridges are supplied one by one into the carrier device from a cartridge housing device located at the side of the carrier device. A cartridge set in a carriage or the carrier device is retained in position by the arms and transferred to the printing machine by driving the carriage with a motor of a driving unit along a guide path. The carriage has a cartridge retaining mechanism and an arm locking mechanism.

Abstract: The invention provides a dental glass ionomer cement composition comprising (a) an .alpha.-.beta. unsaturated carboxylic acid polymer having a weight-average molecular weight lying in a specific range, (b) a polymerizable unsaturated organic compound having a CH.sub.2 .dbd.C(R1)--COO group, (c) water, (d) an organic aromatic compound having a --SO.sub.2 group, (e) a fluoroaluminosilicate glass powder having a mean particle size and specific gravity each lying in a specific range and capable of reacting with the component (a), and (f) a compound containing at least one element selected from the group consisting of aluminum, iron and tin. This composition can be cured either without recourse to conventional redox reaction systems or without exposure to visible light. It can be used with good-enough physical properties for dental therapy while it is harmless to the dental pulp, and can be stored over an extended period of time.

Abstract: There is enclosed a semiconductor memory device having an internal circuit including a plurality of memory cells which can store data thereinto, respectively, to output, as a first output signal, data in a memory cell selected by an address signal, and an output circuit adapted to receive the first output signal to output a second output signal. Power from the same external power supply is delivered to the internal circuit and the output circuit through power supply terminals, and power supply wirings. The power is delivered to the internal circuit through a resistor formed in the middle of the power supply wirings.

Abstract: The present invention provides an apparatus to prevent the entrance of aquatic species into the intake watercourse having a U-shaped cross section with a narrow bottom and a wide surface, in which oppositely facing electrodes are installed vertically along the side walls on both sides of the intake watercourse, and the distance between the upper ends of the electrodes is made greater than the distance between the lower ends of the electrodes, and a voltage is impressed between the both electrodes. Since the electric barrier intensity is smallest at the surface of water and becomes greater as it goes toward the bottom of water, the river fish moving around the bottom of water make a U-turn when they reach the strong electric barrier, or alternatively, after reaching the strong electric barrier, they move upward to where the electric barrier is weaker and then make a U-turn, thereby the entrance of aquatic species into the intake watercourse can be prevented.
