The present invention relates to a method for manufacturing a polycrystalline semiconductor film that can be used for a semiconductor device. In the method, an amorphous semiconductor film is irradiated with a femtosecond laser to be crystallized. By laser irradiation using a femtosecond laser, when an amorphous semiconductor film over which a cap film is formed is crystallized with a laser, it becomes possible to perform crystallization of the semiconductor film and removal of the cap film at the same time. Therefore, a step of removing the cap film in a later step can be omitted.

An ice composition obtained by freezing a liquid containing, dissolved therein, hydrogen peroxide produced by electrolysis; and a method of food storage using the composition. Hydrogen peroxide has a lower rate of dissipation into the air and better suitability for long-term storage than ozone. Furthermore, since hydrogen peroxide is electrolytically produced, it eliminates the trouble of transportation, storage, and dissolution. When seawater is used as a feed water for electrolysis, the ice composition thus obtained has a higher cooling effect because it has a melting point lower than 0° C.

An antenna device includes a resin multilayer board in which a plurality of resin sheets are stacked, and a coil conductor provided in the resin multilayer board. A plurality of line portions of the coil conductor are provided on a lower surface of the resin sheet. When a magnetic material core is preliminarily pressure-bonded to the resin sheet, the magnetic material core is fractured along the line portions and cracks occur. Thus, the resin sheet with the magnetic material core in which the cracks have been formed is fully pressure-bonded together with the other resin sheets.

A disk unit has a voice coil motor to oscillate a suspension arm mounted at the leading end of a head with respect to a disk. The voice coil motor has a voice coil integrally attached to the tail end of the suspension arm, a magnet to cause a magnetic field to act on the voice coil, and a pair of yokes provided in such a positional relationship that the voice coil and magnet are sandwiched therebetween. At least one yoke has a roughly fan-shaped main body and a plate piece portion provided in a condition extended from one end side of the main body. After the formation of the main body and plate piece portion by press working, the yoke is formed by folding the plate piece portion on the main body.

Provided is a solder bump forming method capable of forming solder bumps having a desired constant thickness, without any failure such as copper corrosion, on a mounting board such as a printed circuit board having fine copper electrodes. The solder bump forming method includes: a process in which a prepared mask (5) is placed on a prepared substrate (1) and then a molten solder jet is blown to fill an opening of the mask (5) with molten solder (11a) until the molten solder (11a) exceeds the thickness of the mask (5); a process of removing a part of the molten solder (11a) that exceeds the thickness of the mask (5) to form a solder bump (11) having a predetermined thickness; and a process of removing the mask (5). The molten solder (11a) is molten lead-free solder that includes tin as a main ingredient and at least nickel as a sub ingredient, and further includes one or more other ingredients such as silver, copper, and germanium. The part of the molten solder (11a) that exceeds the thickness of the mask (5) is removed by using a blade or an air cutter or by spraying a solution (18) that includes organic fatty acid having 12 to 20 carbon atoms.

The invention relates to a method and a device for acquiring electronic information about transmission speeds between nodes of an acyclical network, in particular of an IEEE 1394 bus network, precisely one transmission link being present between in each case two of the nodes of the network, and a respective PHY transmission speed of the transmission link being determined by a minimum value of PHY speeds of the nodes of the network lying on the transmission link, in the case of the method the respective PHY transmission speed being determined for one subset of the transmission links in the network by acquiring the PHY speeds of the nodes lying on the transmission links and electronically acquiring minimum values of the PHY speeds; and the respective PHY transmission speed being electronically acquired for another subset of the transmission links, which is different from the one subset of transmission links, on the basis of one of the PHY speeds which have been determined for the nodes lying on the transmission links of the one subset, and electronic topology information about a topology of the network being electronically acquired using optimization means which are formed in a node of the network. The device is provided for carrying out the method.

Specifically, the present invention relates to a method for simultaneously detecting a plurality of pathogens that cause infectious uveitis, one of eye infections from samples such as anterior chamber fluid or vitreous by polymerase chain reaction (PCR), and a kit for carrying out the method.

A guillotine-style cigar cutter. The cutter includes a body with a central aperture and a pair of blades disposed on opposite sides of the aperture and configured to move translationally across the aperture to cut an end of a cigar in preparation for smoking. Magnets are disposed to each blade to provided movement of the cutter open or closed depending on the orientation of the magnetic poles relative to one another.

An integrated system for synthesis of a film-forming precursor, consumption of the precursor and formation of a thin film on a substrate is provided. The integrated system includes a raw material source, a precursor synthesis chamber in communication with the raw material source, a thin film processing chamber in communication with the precursor synthesis chamber for supplying the precursor from the precursor synthesis chamber to the thin film processing chamber in a controlled manner for consumption of the precursor to form the thin film on the substrate, a monitoring system for monitoring of the thin film formation in the thin film processing chamber and/or the precursor synthesis in the precursor synthesis chamber, and a controller for controlling a rate of the precursor synthesis, precursor consumption and/or thin film formation. The rate of precursor synthesis is synchronized with the rate of precursor consumption for formation of the thin film.
