Filed: 1978-05-19
Abstract: PURPOSE:To increase hFE without decreasing the base width of the bipolar transistor but by reducing the base width of the inverter in I<2>L. CONSTITUTION:The n<+>-buried layer 2 and n<->-epitaxial layer are laminated on p-type substrate 1 and then isolated by p<+>-layer 4. The P diffusion is applied to n<->-region A and B to form injector 6, base 7 of the inverter and base 8 of the bipolar transistor at one time. Then thickness t is deleted on the surface of region A with n diffusion applied to form collector 9 of the inverter, channel stopper 10, emitter 11 of the bipolar transistor and ohmic connection layer 12 simultaneously. Then SiO25 is coated with the window drilled to form Al wiring 13. Thus, the base width of the inverter becomes less than the bipolar transistor by t, and thus hFE can be increase for the inverter with the accelerated speed without lowering the dielectric strength of the bipolar transistor. Also, hFE can be controlled by varying t.

Abstract: PURPOSE:To prevent premixed gas from jetting into a combustion chamber by a method wherein the premixed gas at the opening end part of an evaporating cylinder is sucked by an air stream formed to be directed to the premixing chamber. CONSTITUTION:Premixed gas flowing out of a vaporizing chamber 29 is turned into a smooth stream, which does not separate at the cylindrical part 5b end of a draining tube 5, by means of a space 16 consisting of a premixed gas sealing plate 15. Because the premixed gas 12 flowing out of the vaporizing chamber 29 is supplied into a premixed gas chamber 9 by the sucking action, which is developed by forcing the primary air 11' jetting at high speed through the air holes 18 of a blasting tube 1a, the interior of the space 16 is more vacuumed than the neighborhood of the outlet of the vaporizing chamber 29. Consequently, the flowing of the premixed gas 12 due to the rotation of the draining tube 5 through the gaps between the flange part 6a of the bottom plate of a combustion chamber and the cylindrical part 5b and between the flange part 15a of the premixed gas sealing plate and said cylindrical part 5b into the combustion chamber 13 can be prevented from occurring.
