摘要： In producing vehicles by using a plurality of production lines allowing the vehicles to successively pass through a welding step, a coating step and an assembling step, in accordance with an increase or decrease in the production of vehicles in the respective production lines, some of the vehicles in one of the production lines which has less margin for producing vehicles are transferred, after passing through said welding step, to another production line between a welding step and coating step which another production line has more margin for producing vehicles. With this arrangement, when it becomes necessary to increase or decrease the production of vehicles in the respective production lines, it is possible to produce vehicles with high efficiency without changing the production ability in the respective steps after passing through the welding step, only by adjusting the production of vehicles in the welding step in the production line which has less margin for producing vehicles.

摘要： Base regions of first and second stage transistors are formed in a semiconductor substrate consisting of low and high resistivity collector layers, and emitter regions are formed in the respective base regions. The emitter region of the second stage transistor has an interdigital structure with a plurality of finger portions, and an emitter surface electrode is formed on the emitter region of the second stage transistor. The second stage transistor emitter surface electrode has an extending portion at a position spaced apart from a transistor operation region where the finger portions are formed. An emitter connection electrode is formed on the extending portion, and a lead is connected by soldering or the like to the emitter connection electrode. In a portion of the emitter surface electrode extending from the emitter connection electrode to the transistor operation region, slits are formed such that they are bypassed by emitter current so that the lead resistance from each finger portion to the emitter connection electrode is substantially uniform.

摘要： Producing vehicles by using a plurality of production lines allowing the vehicles to successively pass through a welding step, a coating step and an assembling step in each line, in accordance with an increase or decrease in the number of vehicles to be produced in the respective production lines, some of the vehicles in one of the production lines which has less of a margin for production are transferred, after passing through the welding step, to another production line at a portion between its welding step and coating step which line has more of a margin for production. With this arrangement, when it becomes necessary to increase or decrease the number of vehicles in the lines, it is possible to produce vehicles without changing the production ability in the respective steps after the welding step, only by adjusting the number of vehicles in the welding step of the production line which has a less of a margin for production.
