Abstract: Connector housings having plural kinds of terminals (plated with different materials, e.g.) are mounted at predetermined locations, positioned and secured by a drive means. A sensor probe which receives a light, of a color detection device, is transferred successively to the locations opposite to the terminals. A color sensor senses a level of a specific color component of the light received by the sensor probe. The sensed level is compared with a predetermined reference level and it can be determined based upon whether the sensed level is higher than the reference level, the kind of the terminals in the connector housings.

Abstract: An auto focusing apparatus of a scanning electron microscope includes an auto focusing mechanism which calculates a focus evaluation value, using an electron signal or picture signal generated from a specimen when the specimen is scanned by an electron beam focused by an objective lens, and controls an exciting current of the objective lens according to said focus evaluation value. A focus correction value register and a focus correction mechanism for correcting the focused position determined by the aforementioned auto focusing mechanism by as much as the correction value registered in the focus correction value register are provided.

Abstract: In an apparatus that prepares wires necessary for electric wiring by measuring and cutting a length of a wire fed from a wire paying-out device, conveying the cut length of wire in a direction perpendicular to the axial direction of the paid-out wire, stripping wire end portions, and pressing an electrical connector by a connector pressing device, the present invention provides a configuration in which the apparatus can selectively comprise a connector pressing unit composed of a connector pressing device and a pedestal for supporting it on a platform next to the location of the above stripping device, whereby it will facilitate production on many-kinds-and-small-amounts basis as it needs no programming time or adjustment for the replacement of lots.

Abstract: An improved pigmented product is obtained by a pigmenting method comprising the steps of:treating a cellulose fiber textile product with a cationic compound; andtreating the thus-treated textile product by immersing it in a aqueous dispersion containing a pigment and an anionic compound.

Abstract: A dyeing method comprising a process of treating a cellulose fiber textile product with cationic compound and another process of treating the thus-treated textile product by immersing it in a dispersion containing thermochromic material and/or photochromic material.
