Inventor: OBA HIDEHIRO
IPC: F02D41/14
Filed: 1989-06-08
Abstract: PURPOSE:To speedily make the learning coefficient nearly equal to the value with which mixed gas obtains an aimed air-fuel ratio by renewing the learning coefficient by using the learning coefficient with which mixed gas obtains the aimed air-fuel ratio, as standard learning coefficient when the engine temperature is lower than a prescribed temperature. CONSTITUTION:A fuel injection control means B controls the fuel injection quantity supplied from an injection valve 12 on the basis of the output of an oxygen concentration detector 19 so that the mixed gas obtains an aimed air-fuel ratio. The first learning coefficient renewal means F renews the learning coefficient for correcting the fuel injection quantity so that the mixed gas becomes equal to the aimed air-fuel ratio when the engine temperature detected by a detecting means D is high and the difference exceeds a prescribed value, on the basis of the difference between the lean time and rich time of the mixed gas which is calculated by a difference detecting means E, in the acceleration operation detected by a detecting means C. Further, when the engine temperature is lower than a prescribed temperature and the difference exceeds a prescribed value, the second learning coefficient renewal means G uses the first learning coefficient as standard learning coefficient, and performs renewal so that the mixed gas obtains the aimed air-fuel ratio. Thus, air-fuel ratio can be maintained at the aimed air-fuel ratio.

Title: Semiconductor device
Inventor: MAKI TOMOKAZU
IPC: H01L21/322
Filed: 1986-06-19
Abstract: PURPOSE:To reduce stress in a semiconductor element section of an operational region as well as to reduce reverse leak current, by hollowing a substrate to provide a groove in at least a part of a region between a thick oxide film region and the operational region. CONSTITUTION:A thick oxide film 2 is formed on an N-type semiconductor substrate 1 except an operating region 5. Grooves 3 are provided along the ends of the thick oxide film 2 adjacent to the operating region 5 by hollowing the semiconductor substrate 1. When a region of the thick oxide film 2 is formed by thermal oxidation, the volume thereof is increased and the increase in volume gives stress to the operating region 5. The stress, however, can be blocked by the grooves. In this manner, the semiconductor substrate is rarely damaged by defects in crystal during subsequent processes such as diffusion oxidation or the like, as far as it is subjected only to thermal stress in these processes. Accordingly, an element having little reverse leak current can be ontained in a stable manner.

Filed: 1981-09-11
Abstract: PURPOSE:To reduce the variance of the bias value of an input gate circuit agaist the variance of the ambient temperature, by controlling a bias setting circuit by an inverted level setting circuit during the time from the elapse of the hold time to the input of the next trigger pulse. CONSTITUTION:When the base potential of a transistor TR Q1 becomes an in- verted level V'1 or less by the trigger pulse, which is applied to the base of the TR Q1, in the trigger pulse waiting time, states of TRs Q1 and Q2 are inverted and are made non-conductive and conductive respectively to drive a sweep circuit. Next, when the sweep signal reaches a cartain level, a gate controlling circuit becomes non-conductive by a hold-off circuit, and the base voltage of the TR Q1 exceeds the second inverted level V2, and therefore, TRs Q1 and Q2 are inverted. In this hold time, the base voltage of the TR Q1 does not exceed the inverted level V'1. After the hold time, TRs Q1 and Q2 are returned to states in the trigger pulse waiting time, and the base voltage of the TR Q2 is clamped with the emitter voltage of a TR Q4 by an inverted level setting circuit 7.
