There is provided is a semiconductor laser device capable of simplifying fabricating processes with a simple construction and easily mounting two semiconductor laser elements and a monitoring PD on a compact package and a wire bonding method for the semiconductor laser device. There are provided a stem 100 provided with a plurality of lead pins 121 through 124, a sub-mount 160 that is die-bonded onto the stem 100 and has its surface formed integrally with a monitoring PD 140 and two semiconductor laser elements 131 and 132 that are die-bonded onto the sub-mount 160 and have emission light monitored by the monitoring PD 140. A first bonding surface i.e. anode electrode 183 of the monitoring PD 140 and a second bonding surface i.e. end surface 123a of a lead pin 123 that is approximately perpendicular to the first bonding surface are wire-bonded to each other.

An Assembly/processing apparatus includes part tray, work tray where work pieces are placed, conveyor, base machine, part-tray lane, work-tray lane, part-tray transfer apparatus and work-tray transfer apparatus. Conveyor conveys part trays and work trays together, base machine includes assembling means for assembling parts to a work piece, and part tray lane and work tray lane are provided on base machine. Conveyor conveys part trays and work trays to base machine, and respectively places them on each of part tray lane and work tray lane. Then, assembling means takes parts from part tray, and assembles them to the work piece on work tray.

A rotor for an electric rotary machine having an armature core, upper layer coil elements and lower layer coil elements is provided. Each coil element has a straight coil side and a pair of coil ends extending radially at a right angle from the coil side. Each coil end is inclined by a predetermined angle with respect to the coil side in a circumferential direction of the armature core. The lower layer coil side and the upper layer coil side are inserted into corresponding slots in a radial direction. A connector comprising a tip of the coil end of the upper layer coil element and a connector comprising a tip of the coil end of the lower layer coil element are welded together.

A starter which assuredly and simply sealed an outer circumference of one engagement portion between a housing and a yoke or the other engagement portion between the yoke and an end frame with a band-shaped seal member. The banded-shaped seal member covers each engagement portion of the yoke, a center plate, the housing, a brush holder, and the end frame. The seal member has a clearance which is placed to correspond to a notched ventilation hole so that the yoke can be opened in the direction of the starter bottom or the ground.
