摘要： A workpiece dividing method includes: a laser processing step of forming along each street a plurality of minute holes extending in a pulsed laser beam application direction; and a dividing step of pressing the streets by a pressing member to divide a wafer along the streets. The minute hole has one end opening at least one of a front surface and a back surface of the wafer and is decreased in diameter from the one end toward the other end. In the dividing step, the pressing member is pressed against that surface of the front surface and the back surface of the wafer at which the one end of the minute hole is not opening.

摘要： A method of monitoring an operation status of a confined laser cutting tool includes emitting light in the form of laser beams from a laser source. The method includes using a nozzle to form a confining column composed of a liquid. The method further includes forming a confined laser beam, the confined laser beam defined by the confluence of the laser beams and the confining column. The method also includes sensing a characteristic of the confined laser beam with a sensor. The method further includes determining the operation status of the confined laser cutting tool based on the sensed characteristic of the confined laser beam. The method also includes deactivating the laser source when the sensed characteristic of the confined laser beam reaches a predetermined threshold. The method may also include providing an operator notification after deactivating the laser source.

摘要： A fixing method for fixing a terminal to a conductive pattern with a brazing filler metal disposed therebetween includes: a first step of disposing the brazing filler metal on the conductive pattern; a second step of bringing the terminal into contact with the brazing filler metal; and a third step of forming a penetrating hole in the terminal by irradiating a laser beam onto the terminal. In the third step, the laser beam is irradiated onto the terminal in such a manner that the penetrating hole is filled with the brazing filler metal melted by the irradiation of the laser beam.

摘要： This disclosure describes laser machining head cutting gas nozzles that include an inner nozzle having a nozzle opening configured to form a core gas flow, an outer nozzle having an annular gap surrounding the nozzle opening and configured to form an annular gas flow, and a sleeve in the annular gap, wherein the sleeve is arranged to be axially displaceable between a rearward position and a forward position, wherein the sleeve projects beyond the inner nozzle at least when in the forward position, and wherein the sleeve widens a cross-sectional area of the outer nozzle to a variable degree as the sleeve is displaced from the rearward to the forward position. Methods of using a cutting gas nozzle are also described.

摘要： An apparatus for high speed laser drilling of tablets, particularly controlled-release tablets is disclosed. The apparatus comprises of a rotary disk (118) with radial slots (401) to hold the tablets in position with help of centrifugal force. The apparatus further comprises a laser system (120) configured to fire a laser beam in order to draw a line of required length on tablets to drill a precise hole at high speed. The laser system (120) is enabled to draw a line on tablet at a speed equal to that of rotational speed of tablets on the rotary disk (118).

摘要： A bonded structure is made of a first member and a second member which are bonded to each other. At least one bore having an opening is formed in a surface of the first member, and the second member is filled in the bore of the first member. The bore is defined by a diameter-increasing portion whose opening size increases in a depth direction from a surface side toward a bottom of the first member, and a first diameter-decreasing portion whose opening size decreases in the depth direction from the surface side toward the bottom. The diameter-increasing portion is formed on the surface side, and the first diameter-decreasing portion is formed on a bottom side.
