摘要： An ultraviolet-curable and alkali-developing type photo solder resist ink comprises an epoxy resin obtained by extending chains of an epoxy compound by an isocyanate compound having at least two isocyanate groups per one molecule of the isocyanate compound, an ultraviolet-curable resin having carboxyl group and an ethylenically unsaturated group having a photopolymerization capability, a photopolymerization initiator, and a diluent. The resist ink shows a wide precuring acceptable width for providing an extended shelf life, a good tacky-dry property after a precuring step, excellent light-sensitivity at an exposing step, superior resolution, and improved removability of a film of the resist ink by an alkaline solution at a developing step. In addition, a solder resist obtained by a post-baking step of the resist ink film provides excellent resistances to molten solder and gold plating.

摘要： Periphery detectors are arranged along the longitudinal direction of the log which is to be rotated one revolution around a temporary center, thereby a plurality of peripheries of cross sections along the longitudinal direction are detected for the log. The direction of the largest right circular cylinder is determined according to the largest inscribed circles for the peripheries of three cross sections (i.e., the ones adjacent to both the ends of the log and the one in the middle of the log) and the largest right circular cylinder itself is determined according to the peripheries of all cross sections detected. Thus the center line of said largest right circular cylinder is adopted as the turning center. The positions of a pair of inclined beams or swing arms are adjusted for canceling the deviation between the turning center and the temporary center. Furthermore, the largest radius of the log rotation around the turning center is determined from all said cross sections detected, and then the planer table is located in the stand in a position where the planer table never invades said largest radius of log rotation.

摘要： Periphery detectors are arranged being juxtaposed closely, along the longitudinal direction of the log which is to be rotated one revolution around a virtual center, thereby a plurality of peripheries of cross sections along the longitudinal direction are detected for the log. The direction of the largest right circular cylinder is determined according to the largest inscribed circles for the peripheries of three cross sections (i.e., the ones adjacent to both the ends of the log and the one in the middle of the log) and the largest right circular cylinder itself is determined according to the peripheries of all cross sections detected. Thus the center line of said largest right circular cylinder is adopted as the turning center. The positions of a pair of inclined beams or swing arms are adjusted for canceling the deviation between the turning center and the virtual center. Furthermore, the largest radius of the long rotation around the turning center is determined from all said cross sections detected, and then the planer table is located in the stand in a position where the planar table never invades said largest radius of log rotation.
