Title: Air-to-fuel ratio control method for internal combustion engine
Inventor: YAEGASHI TAKEHISA
IPC: F02D41/14
Filed: 1981-08-10
Abstract: PURPOSE:To enhance the accuracy of air-to-fuel ratio control and the purifying performance of exhaust gas over a wide range of the load on the engine etc. by setting a map for the constant of feedback control made by an air-to-fuel ratio sensor according  to the characteristics of the sensor and by reading this map for making the optimum feedback control. CONSTITUTION:Output from the air-to-fuel ratio sensor to sense the oxygen density is  related to the air-to-fuel ratio feedback correction factor f(A/F) through treatment including an integral process, to provide such feedback constants as reversing delay times TDL, TDR, skip widths RSL, RSR, integral constants KIL, KIR, etc. The ratio of the  amount of taken-in-air a (16) to the revolving speed of engine N (22) shall be mapped  with respect to the speed N with at least one of the abovementioned constants, for  example time TDL, being matched previously with the characteristics of the air-to-fuel ratio sensor 36, and be put in memory in the ROM66 of the control circuit 50. Accordingly, the basic injection time for the fuel can be corrected by determining the  abovementioned factor f(A/F) through read-out of the time TDL on accordance with the condition of loading a/N of the engine to be followed by output processing of the sensor 36. Thus the injector 44 and idling speed control valve 48 are feedback controlled.

Title: Security document and method for forming it
Inventor: SATO KOHEI
IPC: B41J21/00
Filed: 1998-04-21
Abstract: PROBLEM TO BE SOLVED: To prevent leakage of a secret document by forming a line feed width of a specific line corresponding to a management number or manager name in a sentence different from that of other normal line, thereby specifying the manager or the document at each document even in a copy document in which the number is intentionally deleted. SOLUTION: For example, in a document 1 in which 002 is attached as a management number 12, a line feed width between a second line and a third line from the beginning is set to a line feed width singular line 11s set wider than the line feed width of the other normal line. The line 11s corresponds to the number 12 one by one, and if it is not duplicated with a document of the other management number, any position can be set to a line feed width singular line. Such a line feed width singular line 11s is provided and hence even if the number 12 is deleted when the document 1 is copied, the source of the document 1 can be clarified.
