Title: Electronic controlling device for fuel injection type engine
Inventor: MATSUOKA HIROKI
IPC: F02D41/26
Filed: 1981-06-04
Abstract: PURPOSE: To avoid a surging phenomenon generated upon deceleration by a method wherein the condition of the decelerating operation of the engine is detected by utilizing the signals of an air amount senser and an gine revolving number senser and thereby effecting correction of the increasing amount of the fuel for deceleration.  
     CONSTITUTION: A suction air volume Q/N per one stroke of the engine is calculated by the flow amount Q of the air and the revolving number N of the engine in a first step, subsequently, the average value (Q/N)a of the suction air volume during a given period is calculated. Next, the calculation of the present suction air volume (Q/N)-the average value (Q/N)a is effected and a decision whether the difference Δ(Q/N) is larger than zero or not is effected. When this difference is larger than zero, it is under an accelerating operation, but, when it is smaller than zero, it is under the decelerating operation. When the engine is decided to be under the condition of the deceleration operation, the standard fuel supplying amount is corrected to increase and thereby avoiding the generation of surging upon deceleration.

IPC: C03C4/20
Filed: 1987-04-10
Abstract: PURPOSE:To contrive to improve transparency and corrosion resistance to acid and alkali, by blending SiO2 with oxides of Al, Na, K, Sr and Ba in specific ranges. CONSTITUTION:A high expansive glass composition consisting of 50-60mol.% SiO2, 3-10mol.% Al2O3, 5-15mol.% Na2O, 5-15mol.% K2O, 0.3-0.7mol.% Na2O/(Na2O+K2O), 5-15mol.% SrO and 5-15mol.% BaO. When SiO2 is <40mol.%, chemical durability is lowered and when SiO2 exceeds >60mol.%, melting properties and a coefficient of expansion are dropped. When Na2O and K2O are <5mol.%, raising effects on melting properties and coefficient of expansion are small and when Na2O and K2O exceed 15mol.%, chemical durability is lowered and the component ratio is 0.3-0.7 because too much partiality reduces chemical durability. SrO and BaO improve melting properties and coefficient of expansion without lowering chemical durability in comparison with Na2O and K2O, when SrO and BaO are <5mol.%, the effects are small and when SrO and BaO exceed 15mol.%, chemical durability is lowered and devitrification likely occurs.
