CONSTITUTION:An N<+> GaAs layer is provided on the surface of a single crystal substrate of N type GaAs by using AsH3-Ga-HCl-H2 series gas, and an N<-> layer is grown to the specified thickness in the gaseous phase. The growing is stopped, As component is flowed at a specified flow rate, and the etching is performed by HCl. The more the flow rate of the As component, the smoother the profile of the change in carrier concentration. Then a specified amount of the N type dopant is supplied, and the N<-> layer is grown. After the specified thickness is obtained, the growing is stopped. HCl for Ga transportation is flowed at a specified flow rate, other HCl is introduced, and the etching is performed. If the flow rate of HCl for Ga transportation is 2X10<-4>mol/min. or more, the steep rising of the carrier concentration with a dip can be obtained. In this constitution, the GaAs epitaxial layer with the N<+>-N<->-N<+> structure can be obtained with good reproducibility.

Abstract: The object is to prepare a high-molecular-weight polyester in such a way that it is advantageously possible to produce even relatively small amounts of very high molecular weight in a very short time. This is achieved by the preparation of a polyester having an alkenediol content by continuing the polycondensation step to a viscosity number of from 50 to 140 cm<3>/g and subsequently subjecting the resultant polyester to solid phase postcondensation until the requisite viscosity number has been reached. The novel process enables high-molecular-weight polyesters having the desired property profile to be obtained.

Abstract: PROBLEM TO BE SOLVED: To form a precise and easy judgement of deterioration of an exhaust emission control catalyst while improving the fuel economy performance. SOLUTION: In this hybrid vehicle, oxygen sensors 28, 29 are located upstream and downstream from a three way catalytic converter 13, which is installed in an exhaust passage 12 of an engine 1. When the reversing ratio A/B, where A is a reverse rotational speed between rich mixture and lean mixture of the upstream oxygen sensor 28 and B is a reverse rotational speed between rich mixture and lean mixture of the downstream oxygen sensor 29, is below a threshold value for determination of deterioration, a three way catalyst is judged to be deteriorated.  At this time, the engine 1 is operated basically with a high degree of efficiency (lower rotational speed and high load) so as to enhance the fuel economy, and when the deterioration of the three way catalyst is diagnosed, the engine 1 is operated at a lower speed under high load so as to obtain an intermediate exhaust gas volume appropriate for the diagnosis of deterioration by the reverse ratio. With this arrangement, of an exhaust emission control catalyst is judged to be deteriorated precisely and easily.
