METHOD OF LASER SCRIBING FIRST AND SECOND TRANSPARENT ELECTRICALLY CONDUCTIVE LAYERS DEPOSITED ON RESPECTIVE OPPOSING FIRST AND SECOND SURFACES OF A TRANSPARENT SUBSTRATE
The present application describes a method for laser scribing first and second transparent electrically conductive layers (14, 14′) deposited on respective opposing first and second surfaces (12, 13) of a transparent substrate (11), the method comprising: directing a first laser beam (21) through one or more lenses (22) to a focal spot on or closely adjacent to the first surface (12) of the substrate (11), such that the focusing laser beam (21) passes through the second electrically conductive layer (14′) and the second surface (13) of the substrate (11); initiating relative movement between the first laser beam (21) and the substrate (11) in two axes in a plane orthogonal to the axis of the first laser beam (21) to scribe a first pattern in the first electrically conductive layer (14); directing a second laser beam (21′) through one or more lenses (22′) to a focal spot on or closely adjacent to the second surface (13) of the substrate (11), such that the focusing laser beam (21′) passes through the first electrically conductive layer (14) and the first surface (12) of the substrate (11), initiating relative movement between the second laser beam (21′) and the substrate (11) in two axes in a plane orthogonal to the axis of the second laser beam (21′) to scribe a second pattern in the second electrically conductive layer (14′).
METHOD FOR PRODUCING GLASS SUBSTRATE AND GLASS SHEET
A method for producing a glass substrate according to the present invention includes the steps of: (I) forming a through hole (11) in a glass sheet (10); (II) forming a resin layer (20) on a first principal surface of the glass sheet (10) using a resin composition sensitive to light having a predetermined wavelength λ.sub.1; (III) photoexposing an area of the resin layer (20) that covers the through hole (11) by irradiating the area with light U having the wavelength λ.sub.1 and applied from the direction of a second principal surface of the glass sheet (10); and (IV) forming a through-resin hole (21) by removing the area photoexposed in the step (III). The glass sheet (10) protects the resin layer (20) from the light U so as to prevent the resin layer (20) from being photoexposed by beams of the light U that are incident on the second principal surface of the glass sheet (10) in the step (III).

Method and Apparatus for Manufacturing an Absorbent Article Including an Ultra Short Pulse Laser Source
The present disclosure relates to methods and apparatuses for assembling absorbent articles, and more particularly, methods and apparatuses for imparting a line of weakness into one or more layers of an advancing substrate and separating the substrate along the line of weakness to form a separation edge. The advancing substrate may be a belt assembly including an outer layer, an inner layer, and one or more elastic strands disposed between the outer layer and the inner layer. The belt assembly may be rotated on a process member about a longitudinal axis of rotation. The process member may advance the belt assembly to one or more ultra short pulse laser sources. The ultra short pulse laser source imparts a line of weakness into the belt assembly. A trim removal member may be used to separate the line of weakness forming a trim portion and a separation edge.
Method Of Laser Joining Of Dissimilar Materials With Ultrasonic Aid
A new ultrasonic aided laser joining method (UAL) for bonding dissimilar materials has been developed. The method is capable of eliminating the laser-induced bubbles at the bonding faces and to improve the joint strength over that of the conventional laser-assisted metal and plastic joining method (LAMP). Some experiments on joining titanium to polyethylene terephthalate have been conducted to show the superiority of UAL over LAMP. The results showed that the joint strength, measured in terms of failure load, was significantly increased when ultrasonic vibration was employed during laser joining. For the LAMP joined specimens, fracture normally occurred at the metal-plastic interface, whereas for the UAL joined specimens, fracture normally occurred in the parent plastic part. The improvement in joint strength is mainly due to the elimination of pores in the resolidified plastic. In addition, ultrasound vibration promotes chemical bonding between the plastic and metal parts, and this is supported by the XPS results.
