Title: Air-fuel ratio controlling method
Inventor: TAKAO MITSUNORI
IPC: F02D41/04
Filed: 1983-04-14
Abstract: PURPOSE:To prevent drastic change of the air-fuel ratio, by delaying calculation of a new injection quantity of fuel or varying a correction factor for EGR (exhaust-gas recirculation) gradually in case that the correction factor for EGR is varied over a plurality of separate regions of a map. CONSTITUTION:A basic injection quantity Tp of fuel is calculated from the pressure in an intake pipe or the throttle opening and the engine speed. At the time of starting recirculation of exhaust gas, the basic injection quantity Tp of fuel is corrected by use of a correction factor f(EGR)1 stored in a map, and judgement is made whether the correction factor f(EGR)1 is equal to the previous correction factor f(EGR)0 or not. In case that f(EGR)1 is not equal to f (EGR)0, the correction factor is varied gradually or otherwise the timing for changing the correction factor f(EGR)1 to f(EGR)0 is delayed. By employing such a method, it is enabled to prevent drastic change of the engine speed or torque.

Filed: 1993-03-25
Abstract: PURPOSE:To display inputted pictures corresponding to the information of vertical/horizontal by providing a means for adding the information relating to the vertical/horizontal of the pictures to the inputted pictures. CONSTITUTION:An operator selects whether a document to be inputted is vertical or horizontal with naked eyes and the information of vertical or horizontal is inputted by selecting either 'vertical' or 'horizontal' with an icon 3.

Abstract: PURPOSE:To improve sound absorbing characteristic in a wide frequency band by gathering numberless granular bodies to stick their contact parts with adhesive agent, and forming continuous thin holes in its inside, and providing many recesses on the surface of a sound absorbing plate. CONSTITUTION:The contact part of numberless granular bodies 2 is made to adhere with an adhesive agent 3 such as binder resin, and continuous thin holes 4 are formed inside the contact part. Sound incident on a sound absorbing plate is absorbed by energy damping caused by friction in the thin hole 4. Many recesses 5, 6, 7 being circular, squre and octagonal are formed on the sound absorbing plate with their depth kept the same, and the circular recess 5 is provided with a stepped part 5a at the middle in a depth direction, and its surface side is formed larger in a diameter than its deep side. The frequency characteristic of sound absorbing rate is optionally regulated by the thickness of the sound absorbing plate, and the size, depth, shape and arrangement of the recesses 5 to 7. In addition as occasion demands, a concrete layer is overlapped on the back of the sound absorbing plate to give noise insulating ability. Thus the width of sound absorbing objective frequency can be optionally regulated to improve the sound absorbing characteristic.
