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.

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.

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.

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.

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.

A code data reading apparatus for photographic film comprises a light emitter 23, lenses 22a and 22b, and a sensor 21. Wherein a bar code 24 recorded on a film F is exposed to light from the light emitter 23 and the enlarged optical image is projected by the lenses 22a and 22b on the detecting surface of the sensor 21.

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. The sheet is brought into contact with one of several kinds of developing solutions in tanks which are adapted to be raised into contact with the sheet one after another. Any excess solution applied to the sheet is removed by a squeezer. After this first development cycle, the table is turned by 180 degrees and moved toward the exposure unit again for another cycle of development. This cycle is repeated as many times as the number of colors used.
摘要:
A semiconductor package that has a superior high frequency characteristics and that can obtain a large area for an internal wiring pattern is provided. According to the present invention, a semiconductor package includes: a multilayer printed wiring board 12, and an IC chip, mounted on the obverse face of the multilayer wiring board 12, and multiple bump terminals 16, mounted on the reverse face. Each bump terminal 16 includes an insulating core 42 having a flat face 40 and a conductive coating deposited on all external surfaces except that of the flat face 40. The end faces of the conductive coatings 44 appear like rings around the insulating cores 42, and are soldered to annular connection pads 52 formed on the reverse face of the multilayer printed wiring board 12. Vias 36 are arranged immediately above the bump terminals 16, and clearance holes 34, the diameter of which is smaller than the diameter of the bump terminals 16, are formed in internal wiring patterns 28 and 30 to permit the passage of the vias 36.

摘要:
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.
