Title: Control method for idle speed of internal combustion engine
Inventor: NARITA MORIO
IPC: F02D29/04
Filed: 1986-10-02
Abstract: PURPOSE:To enable an engine, when it is placed in an idle condition, to hold a stable idle speed, by improving the flow characteristic of an air flow control valve provided in a bypass passage. CONSTITUTION:In the case of a power steering device being actuated when an engine is placed in an idle condition, an amount of air, passing through a passage 5, is changed as shown in the drawing by controlling an air flow control valve 10, provided in the second bypass passage 5, to be opened and closed. That is, the amount of air continues increasing before it reaches a predetermined amount A after a control pressure of oil exceeds the preset pressure P1. And if the amount of air reaches the predetermined amount A, no change is generated in the amount of air before the control pressure of oil exceeds the preset value of pressure P3. Consequently, air-fuel ratio in the initial time of power steering operation obtains a lean state due to an injection delay of fuel, but the air-fuel ratio comes to be lean to a small extent because the control pressure of oil generates no change between the pressures from P2 to P3. While a flow of air in the bypass passage 5 increases if the control pressure of oil exceeds the value P3, but the air-fuel ratio comes to be lean to a small degree with the amount of air smaller than the conventional amount of increase (dotted line), and the possibility of an engine stop small decreases.

Abstract: PURPOSE:To obtain the title vapor growth device capable of reducing consumption of a raw gas and preventing the deposition of the residue on the inner tube by mounting a substrate on the inside of a through hole made in a crystal growth substrate holder, and passing all the raw gas and carrier gas through the through hole.

The raw gas is simultaneously introduced 1f along with the carrier gas to grow an n type GaAs crystal. Meanwhile, the substrate holder 3 is kept at 650 deg.C, and a gaseous mixture of trimethylgallium, SiH4, AsH3, and H2 and gaseous H2 as the carrier gas are supplied into a reaction tube 1. As a result, an n type GaAS crystal (n = about 1X10<17>) is obtained on the substrate 2 at the growth rate of 30Angstrom /sec. When a crystal is grown in the conventional vapor growth device under the same conditions, the growth rate is reduced to about 1/3.

Abstract: PURPOSE:To perform fault recovery by measuring the processing time of a bus master to detect its abnormality and transferring the control to another normal bus master. CONSTITUTION:When a bus master 3 gets the control right of a bus 17 to start the control of the bus 17, a timer 5 starts counting. When the bus master 3 does not terminate the control of the bus 17 after a normal processing time elapses, the timer 5 terminates counting of a preliminarily determined prescribed time to judge the bus master 3 to be abnormal, and a hold signal line 12 is forcibly invalidated through a gate 7 to deprive the bus master 3 of the control right of the bus 17. Further, a main bus master 2 is interrupted through a signal INT line 15. The main bus master 2 gets the control right of the bus 17 instead of the bus master 3 where abnormality occurs. Thus, an interruption handling program for fault recovery is started, and the main bus master 2 discriminates the cause of abnormality to perform a proper processing, and the operation of a system is continued.
