A submerged nozzle replacing device comprises a slide valve device 6 for controlling the amount of outflow of molten metal flowing out of a molten metal container, a holding cylinder 21 for a submerged nozzle 9 supported in a vertical posture below the slide valve device, and a guide bar 33 having a pair of parallely provided rail members 33a supported in a horizontal posture by a piston rod of the cylinder, and fitted onto a nozzle case 10 at the upper end of the submerged nozzle 9 to hold the ...

In a lead frame conveying method and apparatus used in, for instance, a wire bonding machine, a detection of the leading end of a lead frame supplied from a lead frame magazine and a positioning of the lead frame on a lead frame path are executed by a positioning sensor which is installed in the vicinity of a bonding position; and after the positioning, the lead frame is chucked by feeding claws so that a first bonding portion on the lead frame is conveyed by the feeding claws to the bonding pos...

In a fixed type discharge electrode system employed for forming a ball on a bonding wire so that a discharge electrode is provided near the tip end of a bonding wire, a gas, such as air, is blown to the spark discharged between the discharge electrode and the tip end of the bonding wire in the direction from the discharge electrode so as to bend the discharged spark and the discharged spark that faces the bonding wire is positioned beneath the bonding wire.

A substrate transporting device used in the process of manufacturing, for instance, semiconductor chips including a substrate guide comprised of a substrate guide rail which guides one side of each substrate and a substrate supporting plate which supports another side of the substrate, feeding claws for feeding a substrate to, for instance, a bonding position, the feeding claws being provided on a feeding claw holder and extending in the direction perpendicular to the substrate supporting plate,...

On both the sides of sheet S1 which is a crepe paper processed by crinkling process and has a low expansion ratio due to the spread of crinkles on liquid impregnation or which is a non-crinkle-processed paper with no expansion, is bonded sheet S2 which is processed by crinkling process and has a higher expansion ratio than the expansion ratio of the sheet S1 due to the spread of crinkles on liquid impregnation. The sheet S1 and the sheet S2 are partially bonded together at each of adhesive parts...

An ink cartridge which is provided therein with a spring assembly for generating a negative pressure inside the cartridge being refilled with ink while applying a compression onto the spring assembly. The compression is removed so as to allow the spring assembly to expand and to generate the negative pressure. The application and removal of the compression is provided by a pressure tool that has an elastic metal strip bent so as to press the spring assembly; and the ink refilling is accomplished...

After overlaying an inner sheet of a coarse and bulky non-woven fabric on an outer sheet, super absorbent polymers (SAP) are dispersed on the inner sheet. Folding inwardly both the sides of the laminated body composed of the outer sheet and the inner sheet so as to face the inner sheet together to overlay both the ends together, the SAP are wrapped by means of the outer sheet and the inner sheet from the top and bottom thereof. Then, applying heat over the outer sheet, the outer sheet and the in...

A telescopic rod antenna according to the present invention includes an antenna element and a waterproof ring-shaped seal member which is inserted in a ring-shaped gap in a joint between two rods of the antenna element. The ring-shaped seal member is obtained by shaping a thermoplastic resin film strip, on which at least one projecting portion is formed in its longitudinal direction, like a ring and compressing and inserting a ring-shaped film into the ring-shaped gap. A plurality of ring-shaped...

A sensor section for obtaining identification data from a bill passing through a bill transfer path can selectively be mounted in a plurality of positions on the body of a bill identifying apparatus. The sensor section is mounted in one of the mounting positions, and a certain region of the bill passing through the transfer path is sensed by means of a sensor section to obtain identification data. When the use of forged bill is identified by the bill identifying apparatus, or after the machine h...

A container for storing liquids such as ink to be refilled in an used, empty ink cartridge for computer printers being to be formed with at least two holes so as to allow the ink to discharge. A hole is made in the container at its mouth portion and then another hole is opened at the main chamber of the container by a piercing device attached to the container or by revealing an air passage so as to introduce external air into the container so as to pressure out the ink into the ink cartridge.
