摘要： A bipolar transistor includes collector, base and emitter regions. The collector region consists of a first semiconductor region of a first conductivity type and formed in contact with a surface of a semiconductor layer. The base region consists of a second semiconductor region of a second conductivity type formed within the collector region to be in contact with the surface of the semiconductor layer. The emitter region consists of a third semiconductor region of the first conductivity type formed within the base region to be in contact with the surface of the semiconductor layer. The transistor also includes collector, base, and emitter electrodes. The collector and base electrodes are connected to the collector and base regions at opposite edges of a single opening formed in a field insulating film covering the surface of the semiconductor layer. The collector and base electrodes consist of a conductor. The emitter electrode is connected to the emitter region and consists of a conductor. The transistor further includes first and second insulating interlayers. The first insulating interlayer is formed between the collector and emitter electrodes. The second insulating interlayer is formed between the emitter and base electrodes. A distance between the collector and emitter electrodes on the surface of the semiconductor layer is substantially the same as that between the emitter and base electrodes.

摘要： There is disclosed a fuel cell cooling plate for eliminating waste heat generated by operation of a fuel cell. The cooling plate consists of an inner substrate layer composed of a soft, deformable plastic or low elastic carbonaceous material, sandwiched between outer substrate layers of a strong gas-impermeable carbonaceous material, and a sealing material. The inner substrate is chased with grooves, which house metal cooling pipes for passage of the cooling medium. The soft, deformable, plastic or low elastic material of the inner substrate can be formed so that the grooves fit tightly around the cooling pipes, preventing formation of any air gaps between the pipes and the grooves. This permits nearly complete circumferential contact between the pipes and the grooves, thereby reducing thermal resistance associated with air gaps, and maintaining a high degree of heat transfer. Further, the plastic or low elastic material of the inner substrate layer can conform to thermal expansion and contraction of the cooling plate and pipes, reducing excessive wear over the lifetime of the cooling plate.

摘要： A variable venturi type carburetor including both inner and outer venturis, a main nozzle for injecting main fuel into the inner venturi and a piston valve displaceably mounted on the outer venturi to move under the influence of negative pressure transmitted from the intake passage. The carburetor further includes an auxiliary fuel nozzle for feeding auxiliary fuel to the outer venturi in response to movement of the piston valve. The auxiliary fuel nozzle is disposed on the outer venturi adjacent to the main nozzle and the center axes of both the nozzles are located on the same or substantially same plane extending in the direction of the intake passage. A bleed air valve is mounted midway of the atmospheric pressure introduction passage which is branched from the auxiliary fuel passage so as to open the passage when higher negative pressure is transmitted from manifold. Further, a vacuum switching valve is mounted midway of the atmospheric pressure introduction passage extending from the negative pressure chamber on the valve piston so as to open the passage when higher negative pressure is transmitted from manifold. One end of each of the atmospheric pressure introduction passages for both the valves is opened to the atmosphere.
