Title: Generator of random number
Inventor: SANO TADASHI
IPC: G06F7/58
Filed: 1981-06-30
Abstract: PURPOSE:To obtain a complete random number, by obtaining an initial data from a random number source every time when a random number group is generated. CONSTITUTION:A timepiece memory 5 is alloted at a prescribed region of a memory 1, and the timepiece data given from a timepiece mechanism 4 is rewritten momentarily to the memory 5. Accordingly the timepiece data of the memory 5 has a change at all times, and as a result the timepiece data which are fetched during the execution of a random number producing program are virtually regarded as random numbers. In such way, the timepiece data is used as the initial value of the random number when the random number producing program is executed. Thus the correlation function is extremely diluted for each random number group.

Title: Fuel injection controller for diesel engine
Inventor: KIZAKI KANJI
IPC: F02D41/04
Filed: 1995-04-27
Abstract: PURPOSE: To prevent an engine from stalling in a low speed range, in a fuel injection controller for diesel engine which gives annealing treatment to fuel injection quantity for restraining the accelerating/decelerating shock of an on- vehicle diesel engine. CONSTITUTION: Based on the operating condition of a diesel engine, fuel injection quantity is computed. While engine speed is dropping, the fuel injection quantity is increased and corrected to prevent engine stall. To restrain accelerating shock, annealing treatment is given to the fuel injection quantity at the time of acceleration. In such a range as vehicle speed SPD<=5km is satisfied, an annealing prohibition flag XQSMA is turned on, taking precedence of accelerating from standstill (steps 302, 304). In such a range as an engine speed NE is smaller than a value where a judged value NE1 is subtracted from target speed NTRG at the time of idling, XQSMA is turned on to prevent engine stall (step 306).
