A three-dimensional laser cutting system by a playback method, adapted to cut work pieces by means of a laser beam. The system comprises a three-dimensional drive machine provided on its main head with a laser head, high speed spindle head and tracer head; a laser unit disposed beside said machine; laser beam delivery means for guiding a laser beam from said laser unit to a laser beam emission nozzle of said laser head; and a computer having a CNC function of driving said tracer head on the basis of a two-dimensional NC tape, and a CTC function of preparing a three-dimensional NC tape on the basis of said two-dimensional NC tape and data obtained by scanning and driving said laser head by a playback method on the basis of said three-dimensional NC tape. The system of the invention may be used for various purposes. When it is used for three-dimensional laser cutting a two-dimensional NC tape of a three-dimensional work piece is prepared, the work piece being scanned by means of said tracer head on the basis of said two-dimensional NC tape, a three-dimensional NC tape being prepared on the basis of said two-dimensional NC tape and data obtained by scanning, then the work piece being cut by means of said laser head on the basis of said three-dimensional NC tape.

A printed circuit board substrate is mounted with electric circuit components to form an electric circuit thereon. The printed circuit board is provided with a land without a piercing hole for electrical connection with an electrode of a chip-shaped leadless element, and a land with an aperture for the insertion of the lead wire of a component or element with a lead, and further a pilot pattern for leading melted solder in spite of the presence of evaporated solder flux gas or air during a solder dipping operation. The pilot pattern may comprise a conductive pattern connecting the land for the leadless element and the land for the element with lead. At least elimination of the solder resist layer on a portion of the conductive pattern to form the pilot pattern.

C. for 1 hour, cold rolling the annealed sheet and annealing the cold rolled sheet at a temperature of 150-250.degree. C. for 1 hour.
摘要:
Leadless electronic parts or the like are transferred from hoppers under the influence of gravity or by forced air through tubes of polygonal cross-section to a prepositioning template. The polygonal cross sections of the transferring tubes tend to damp out oscillatory motion of the parts and to speed their travel through the tubes. Each polygonal, preferably triangular, tube is preferably obtained by deforming a tube of circular cross-section in a forming machine including a plurality of discs arranged so that their peripheries define a polygonal space therebetween through which the tube of circular cross section is driven.
