IPC: F02D41/00
Filed: 1985-03-05
Abstract: PURPOSE:To enable optimum fuel consumption to be alway ensured even if the conditions of an engine are changed, by a method wherein, after the number of idle revolutions is controlled to a maximum value under a state in that a fuel feed amount is maintained at a specified value, a fuel feed amount is decreased depending upon a difference between the maximum number of revolutions and the desired number of revolutions. CONSTITUTION:A CPU 27 of a control unit 25 performs feedback control of the opening of a bypass valve 15 of a number of idle revolutions control mechanism 13 so that the number of idle revolutions is regulated to the desired number of revolutions. Thereafter, an amount of intake air flowing through a bypass passage 14 is increased by increasing the opening of the bypass valve 15 so that the number of idle revolutions is increased to a maximum value in a state in that a fuel feed amount is held at a specified value. Further, a fuel feed amount is decreased so that the numberof idle revolutions is decreased to the desired number of revolutions. After that, the opening of the bypass valve 15 and the fuel feed amount are controlled to the above state, and control during idling is performed. Additionally, the number of revolutions of an engine is detected by a number of revolutions sensor 20.

Title: Production of thin film magnetic head
Inventor: ITO MASARU
IPC: G11B5/31
Filed: 1985-03-05
Abstract: PURPOSE:To attain the accurate pole height with high yield by detecting the electrical contact between two metallic films which hold vertically an insulated layer. CONSTITUTION:The electrical conduction is secured between terminals 19 and 20 or terminals 21 and 22. When a polishing process is carried out further in order to attain the accurate pole height, the contact area is reduced gradually between upper and lower monitor patterns 25 and 23. Then no electrical conduc tion is secured between both patterns when the polishing process proceeds up to a line A-A'. Here the positions of a monitor insulated layer 24 and another insulated layer within an element are set on a photomask so that the layer 24 is closer to the polished surface by a slight amount, e.g., about 0.5mu than the other insulated layer. As a result, no electrical conduction is secured during the polishing process between terminals 19 and 20 of polishing monitors 17 and 18 as well as between terminals 21 and 22. At the same time, the polishing process is discontinued. Thus the prescribed pole height is obtained with high accuracy.
