Title: Control method for fuel injection amount and ignition timing of internal combustion engine
Inventor: MIZUTANI KOICHI
IPC: F02P5/152
Filed: 1986-12-18
Abstract: PURPOSE:To prevent air-fuel ratio from its overrich and overlean states and ignition timing from its excessive advance and excessive delay, by correcting a detection value of an engine load in accordance with a correction amount of delay timing by whether or not knocking is generated. CONSTITUTION:A control circuit 20 controls a fuel injection amount and ignition timing based on a detection value of an engine load by an air flow meter 24 or the like and a detection value of an engine speed by a rotary angle sensor 18. While the control circuit delays the ignition timing, if generation of knocking is detected by an output signal from a knocking sensor 12, further corrects the ignition timing by a correction amount of delay timing in which the ignition timing is advanced when no knocking is generated. Here the detection value of the engine load is corrected in accordance with the correction amount of delay timing approaching the actual value of an engine. In this way, a decrease of an engine output and generation of knocking can be effectively prevented by preventing air-fuel ratio from being overrich and overlean and the ignition timing from excessively advancing and delaying due to a change of the detection value of the engine load caused by a change of the sensor characteristic.

Abstract: PURPOSE:To recover organic substances without using a chilling refrigerant by evacuating the secondary side of a pervaporation membrane to make organic substances permeate through the pervaporation membrane and condensing and recovering the permeated vapor of the organic substances at atmospheric pressure. CONSTITUTION:For example, water solution of 10wt.% ethanol is preheated to 60 deg.C and fed to the primary side 3 of an alcohol permeable membrane module 2. The secondary side 5 of the module 2 is kept at a vacuum of 5Torr. The water solution of alcohol is subjected to pervaporation with the alcohol permeable membrane 4 to produce the compressed vapor of the dense water solution of alcohol, causing the temp. to be decreased, permitting the secondary side (conduit 7) of a vacuum pump to be increased in pressure to 100Torr. After the vapor of 100Torr is cooled by a heat exchanger 10, it is discharged to a line 9 through a vacuum pump 8 at atmospheric pressure and further cooled by a heat exchanger 11 to obtain condensed dense water solution of 30wt.% alcohol. Therefore, to cool and condense the vaporized organic substances, a chilling refrigerant is not needed.

Abstract: PURPOSE:To reduce the manufacturing cost by composing the active layer of polycrystalline silicon layer and the source-drain regions of polycrystalline germanium layer. CONSTITUTION:A polycrystalline silicon film 2 is deposited on a glass substrate 1. The next step is to deposit a polycrystalline germanium film 3 on the deposited polycrystalline silicon film 2 and to open a channel zone A by etching this polycrystalline germanium film 3.

After an SiO2 film is formed on the entire surface of the substrate to form a polycrystalline silicon film, it is selectively removed to form gate electrodes 5 composed of a gate oxide film 4 and polycrystalline silicon. An indium layer 10 is evaporated on the whole substrate and heated to turn the polycrystalline germanium layer 3 into a P<+> type region 3'. An SiO2 film 6 is deposited by CVD info the interlayer insulating film and opened for contact windows, and then Al wiring layers 7 are formed and coated with a passivation film 8. This process allows the manufacture of the title device on a glass substrate at a low temperature process without ion implantation.
