Title: Valve timing control device of internal combustion engine
Inventor: YOSHIOKA MAMORU
IPC: F02D13/02
Filed: 1995-04-27
Abstract: PURPOSE: To obtain the valve timing control device of an internal combustion engine which can suppress the disturbance of an air fuel ratio. CONSTITUTION: The most suitable phase difference of VVT 133 is decided in compliance with the running state of an internal combustion engine, but i happens that the difference δθfrom an actual phase difference becomes large due to the existence of an action delay. In this case, an air fuel correction coefficient is transferred into a rich side because an accidental fire is liable to occur and an air fuel ratio sensor 147 detects a lean state continuously. Therefore, an air fuel ratio correction coefficient upper limit is reduced when the difference δθ becomes large and the air fuel correction coefficient exceeds into the rich side and it is prevented that the air fuel ratio receives disturbance.

Title: Picture processing method
Inventor: SAKURAI AKIRA
IPC: G06V10/28
Filed: 1980-07-29
Abstract: PURPOSE:To perform picture processing suitable for binary-coding of various pictures through setting the best threshold level, by calculating the reference deviation and average value of density levels within constant picture-element areas in every said area by comparing the both. CONSTITUTION:Picture-element information in every one scanning line of an inputted picture signal BS is read in an arithmetic processing part 1 to calculate its average density level mu and reference deviation O. The binary-coding process according logical decisions which correspond to those calculation results is executed for an inputted picture signal DBS sent successively via a one-line shift register 2, in a binary-coding processing part 3. While the processing part 3 binary-codes the one-line picture signal stored in the register 2 temporarily and collectively, a picture signal of the next line is sent to an arithmetic processing part 1 to calculate the density level mu and reference deviation O of the line, thereby achieving real-time processing.
