Abstract: A two-component adhesive for an endoscope and a cured product thereof, the adhesive having a base resin and a curing agent. The base resin contains an epoxy resin (A), and the epoxy resin (A) includes an epoxy resin (a) having an average degree of polymerization of 2 or more. Also disclosed are an endoscope produced by using the adhesive for an endoscope and a method for producing the endoscope.

Abstract: An infrared cut filter including a film that includes a cyanine dye including a cation having a polymethine and a nitrogen-containing heterocycle at each end of the polymethine, and a tris(pentafluoroethyl)trifluorophosphate anion, and a copolymer including a first repeating unit from a first monomer that is an acrylic monomer having a cyclic ether group, and a second repeating unit from a second monomer that is a monomer having a functional group that reacts with the cyclic ether group.

Abstract: A resin composition including a resin R including a repeating unit having a partial structure of Formula (I) or (II): where QA is an ester bond shown in the Formula (I), RA is a substituent group, n1 is any of integers 1 to 5, * is a bonding site with a remainder of the repeating unit, and ** is a bonding site with a phenyl group in the Formula (I); where QB is a linking group or a single bond other than the ester bond of QA in Formula (I), RB is a substituent group, with at least one RB being a hydroxyl group, n2 is any of integers 1 to 5, and * is a bonding site with a remainder of the repeating unit.

Abstract: An infrared cut-off filter, including a cyanine dye and a copolymer. The cyanine dye includes tris(pentafluoroethyl) trifluorophosphate and a cation having a polymethine and a nitrogen-containing heterocycle at each end of the polymethine. The copolymer includes a first repeating unit from a first monomer and a second repeating unit from a second monomer different from the first monomer. The first monomer includes a phenolic hydroxyl group.

Abstract: In order to carry out quick and easy changeover of platens of an electrode unit, a shank holder connects a fixed lower electrode with a platen. Further, a movable upper electrode is connected with another platen by the shank, which is held by the shank holder. The shank holder and the shank are integrally connected with each other, and are positioned in such a manner that the electrodes can perform resistance welding. Merely detaching the shank and shank holder from their respective platens allows the desired electrode units to be mounted on, or removed from, a resistance welder without making any position adjustments of the electrodes. Consequently, adjustment of the positions of the electrodes becomes unnecessary, thereby facilitating quicker and easier changeover of electrodes.

Abstract: A color image pickup 33 picks up a color image of cores 9 soldered to the inner wall of a metal tube 12 of a connector 11 by a solder 16b. A component image of the color of the cores 9 is extracted from the color image. A non-soldered area of the cores 9 exposed from the solder 16b is calculated based on the extracted component image. The calculated non-soldered area is compared with a first threshold value to determine whether or not the cores 9 are satisfactorily soldered (i.e., the wires are satisfactorily connected). Connection of the wires can be checked with a uniform quality and an improved accuracy.

Abstract: A heating apparatus 1 includes a plurality of closable heating units 10 arranged at specified intervals and each provided with a heater 14, a conveyor 20 for conveying the closable heating units 10 along a loop-shaped conveyance path including a setting station 31, an unloading station 32 and a cooling station 33, and a controller for controlling the heater 14 to heat a solder containing wire connector set in the heating unit at the setting station 31 until the heating unit sent out from the setting station 31 reaches the cooling station 33. The heating apparatus 1 thus constructed heats a wire connection, in particular a connector, such that the wire connection is secure and watertight, and has a good working efficiency.
