摘要:
In a laser beam machining method for a wiring board, a machined portion of the wiring board is irradiated with a pulsed laser beam for a beam irradiation time ranging from about 10 to about 200 μs and with energy density of about 20 J/cm2 or more, thereby machining the wiring board, for example, drilling for a through-hole and a blind via hole, grooving, and cutting for an outside shape.

In a laser beam machining method for a wiring board, a machined portion of the wiring board is irradiated with a pulsed laser beam for a beam irradiation time ranging from about 10 to 200 μs and with energy density of about 20 J/cm2 or more, thereby machining the wiring board, for example, drilling for a through-hole and a blind via hole, grooving, and cutting for an outside shape. The laser beam operates at a frequency of more than 67 Hz, and the spot of the laser beam is sequentially moved to different drilling positions for each pulse. After all of many drilling positions in the range of a scan vision are irradiated with the laser beam pulse by pulse, or after the elapse of a time of 15 ms or more from irradiation of the first drilling position, the laser spot is returned to the first drilling position. The spot is sequentially moved once again, and the movement is repeated several times. A pause of 15 ms or more is required between pulses directed to the same drilling position to avoid formation of a thick char layer and projection of glass cloth into the hole.

Two cylinder heads (3, 3) are disposed side by side. Upper side intake valve holes (34a, 34c, 34e, 34g) of one of the cylinder heads (3) and upper side exhaust valve holes (35a, 35c, 35e, 35g) of the other of the cylinder heads (3) are simultaneously machined by a multi-spindle head (24) integrally including intake side tools (26a to 26d) and exhaust side tools (28a to 28d). After moving the one of the cylinder heads (3) upward by a pitch P1 of the intake valves and moving the other of the cylinder heads (3) upward by a pitch P2 of the exhaust valves, remaining intake valve holes (34b, 34d, 34f, 34h) of the one of the cylinder heads (3) and remaining exhaust valve holes (35b, 35d, 35f, 35h) of the other of the cylinder heads (3) are simultaneously machined.

The control system has a structure in which sensor apparatuses each having a data communication function are connected to an electronic control apparatus through a common communication line, and the sensors of the sensor apparatuses are connected to the electronic control apparatus through separate individual signal lines to transmit sensor signals to the electronic control apparatus. The electronic control apparatus is configured to, prior to transmitting communication data to one of the sensor apparatuses through the communication line, set the signal line connected to the selected sensor apparatus in a state in which the voltage of the signal line is outside a variation range corresponding to a voltage range of the sensor signal, and set the signal lines connected to the other sensor apparatuses to each of which the communication data is not addressed in a state in which the voltage of the signal line is within the variation range.

A seat includes a seat supporting carrier. A seat cushion is pivotally mounted on the carrier. The carrier has a swing arm pivotally attached thereto. A seat back is pivotally mounted to the swing arm. The seat cushion is pivotable on a first pivot axis P1 between a laid position and an erected position. The swing aim is pivotable on a second pivot axis P2 between a laid position and and erected position. The seat back is pivotable on a third pivot axis between a laid position and an erected position. When the seat back is in the erected position and the seat cushion is in the laid position, the third pivot axis is positioned higher than the first and second pivot axes. The seat back, by pivoting from the erected position to the laid position, lies on the seat cushion held in the laid position.

In a data processor for processing pieces of input data successively sampled, a memory unit and a plurality of data transferring units for transferring data are provided. Each of the plurality of data transferring units has an upper limit number of data items successively transferable when activated. An activating unit is provided. The activating unit is configured to successively activate, within a predetermined time frame, the data transferring units without all of the data transferring units being deactivated within the predetermined time frame to thereby successively transfer the pieces of input data to the memory unit so as to store the pieces of input data therein.
