  • Publication number: 20100213592
    Abstract: To provide a semiconductor module, a terminal strip, a method for manufacturing the terminal strip, and a method for manufacturing the semiconductor module in which loop inductance is decreased. A terminal strip includes a grounding (GND) conductor, power supply (VDD) conductors, signal line conductors, and insulators. The insulators intervene between the GND conductor and the VDD conductors. Similarly, the insulators intervene between the GND conductor and the signal line conductors. In the terminal strip, since the GND conductor and the VDD conductors are disposed close to each other, mutual inductance between GND wiring and VDD wiring can be increased. Thus, loop inductance can be decreased.

  • Patent number: 6097573
    Abstract: A magnetic information recorder/reproducer can reduce the possibility of breakage of parts and thus lessen the need for maintenance. A resilient member for pressing a magnetic medium against a magnetic head has a resilient, hard guide layer provided on one side thereof facing the magnetic medium. The guide layer prevents the magnetic medium from coming into contact with the resilient member. The resilient member is thus less like to be broken or worn because it does not contact the magnetic medium.

  • Patent number: 6074108
    Abstract: A method of cleaning a film transport unit (5), in which a cleaning leader (80) formed of a synthetic fiber (81) hardened with a resin (82) is transported through a transport path of the film transport unit, and the cleaning leader (80) removes substances adhering to a magnetic head (32a) disposed in the transport path, with said cleaning leader. Preferably, the synthetic fiber is hardened by being impregnated with a resin (82) selected from urethane resin, acrylic resin and silicone resin. Preferably, the cleaning leader (80) is elongated to be an identical or similar shape to a film (2) transported through the film transport unit (5). At least a leading end of the cleaning leader is hardened.

  • Patent number: 6056451
    Abstract: A photographic film processing apparatus for processing long developed film (10b) formed by joining photographic films with a splicing material (13). The apparatus includes a first transport device (40a) for transporting the long developed film. A region of the splicing material in the long developed film is detected in order to cut the long film. A main cutter (60) cuts the long developed film transported by the first transport device, in the region of the splicing material into short films (10a) prior to an exposing process. A second transport device (40b) is provided for transporting the short films to exposure processing units (20, 30). Further, an auxiliary cutter (70) is provided for cutting lateral portions of the region of the splicing material in the long developed film. The region of the splicing material is cut such that a width of an upstream short film is contained within a width at a forward end of a downstream short film.

  • Patent number: 5825462
    Abstract: A film cartridge storage apparatus for storing a plurality of film cartridges 20 stacked one on another. The stored film cartridges 20 are extracted from the apparatus one after another from the lowermost cartridge in association with a pivotal member 83 of an individual feed mechanism 80; 18; 280 having a first arm portion 83a and a second arm portion 83b. The first arm portion 83a of the pivotal member 83 pivots between a first area and a second area to hold the lowermost film cartridge in the first area and also to feed the lowermost film cartridge in the second area. The second arm portion 83b of the pivotal member allows a film cartridge to fall toward the first arm portion in the first area and also prevents a film cartridge from falling toward the first arm portion in the second area.

  • Patent number: 5668645
    Abstract: A photographic printer can process a plurality of films each housed in a separate cartridge concurrently with high efficiency. The printer has a base and a rotary table rotatably mounted on the base. Four cartridge holders are mounted on the rotary table along its circumference at angular intervals of 90.degree.. Mounted on the base around the rotary table are a cartridge supply unit, a scanner unit and a printing/exposure unit arranged opposite to three of the four cartridge holders, respectively. The scanner unit and the printing/exposure unit are provided separately from and driven independently of each other, so that the film processing steps in these units can be carried out concurrently.

  • Patent number: 5612765
    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.

  • Patent number: 4908667
    Abstract: A photographic copying apparatus for reproducing an original on photosensitive paper. A roll of photosensitive paper mounted in a magazine is fed downwardly and cut into sheets. Each sheet is sucked to a vertically arranged suction conveyor and fed down. At a predetermined position, the feed of the sheet stops. An exposure table which is turnable and movable between two points is turned and pressed against the sheet on the conveyor. The suction conveyor stops sucking the sheet while the exposure table starts sucking it, so that the sheet is handed over to the latter. The table now carrying the sheet moves toward the expsoure unit. On its way, it is turned and passed under a corona charger. As the table reaches and the exposure unit, it is turned again and the light reflected by an original is shed on the sheet for light exposure. The table is then turned to bring its sheet carrying side down and moved in an opposite direction toward the conveyor.
