Abstract: A method and an apparatus for perforating a printed circuit board are provided so that the processing efficiency and the board densification can be improved. In test processing, a conductor layer 50i is irradiated with a pulsed laser beam 4a whose energy density is set at a value high enough to process the conductor layer 50i while emission 23a from a processed portion is monitored. Thus, the number of pulses of irradiation required for processing a window in the conductor layer 50i is obtained. An insulating layer 51i is irradiated with a pulsed laser beam 5a whose energy density is set at a value high enough to process the insulating layer 51i but low enough not to process a conductor layer 50i+1 under the insulating layer 51i. Thus, the number of pulses of irradiation required for processing a window in the insulating layer 51i is obtained.

Abstract: A passenger detecting device includes a plurality of weight sensors, a passenger judging and data updating device and an update forbidding device. The weight sensors are arranged at different positions of a seat for respectively detecting weights acting on the seat of a motor vehicle. The passenger judging and data updating device is capable of judging a passenger on the seat based on the loads detected by the weight sensors and updating information on the passenger. The update forbidding device prevents the passenger judging and data updating device from judging the passenger or prevents the information to be updated when a sum-weight fluctuation amount is not less than a first predetermined threshold value, where the sum-weight fluctuation amount is obtained by summing up weight function amounts which are absolute values of fluctuations of the loads detected by the weight sensors.

Abstract: A manufacturing method of a clad material composed of a bronze alloy and a steel is provided, including: scattering a bronze alloy powder on a steel back metal; sintering the bronze alloy powder to obtain a bilayer material having a porous bronze alloy layer on the steel; dry-rolling and a sintering the bilayer material so that the bronze alloy layer has a porosity of 3% or less; and wet-rolling the bilayer material with supplying a rolling oil to surfaces of rolling rolls. The clad manufactured according to this method can be heat-treated without an disadvantage in a conventional wet-rolling that entering rolling oil vaporizes in the bronze alloy layer during the heat treatment to form new voids. Therefore, it becomes possible to make a bronze alloy layer high in density in small times of rolling, thus enabling an increase in production efficiency.

Abstract: A laser machining apparatus in which three or more beam splits are made incident on one machining lens so that high speed machining can be achieved, and the machining quality (shapes, dimensions, accuracy and straightness of machined holes) is excellent. The optical paths of beams A and B having the same polarization direction are aligned almost in one and the same direction by a total reflection/transmission type beam combining means 31c using a difference in incident angle. After that, the optical paths of the beams A and B and the optical path of a beam C different in polarization direction therefrom are aligned almost in one and the same direction by a polarizing type beam combining means 32. Then, the beams A, B and C are made incident on a machining lens 45.

Abstract: A method for determining a position of a reference point in which there is no influence of aberration of a camera lens or the like, but an error caused by a failure in shape of an alignment mark can be reduced. An alignment mark consisting of a plurality of pattern portions (and background portions) centering at a design reference point is provided in advance. Positions of centers of border lines of the patterns are calculated. Obtained coordinate values of the centers are averaged in each axial direction. The averaged coordinate values are regarded as coordinate values of a machining reference point. Thus, even when a defect occurs in any pattern portion, an error caused by the defect is reduced so that the accuracy in machining can be improved.
