Filed: 1986-12-08
Abstract: PURPOSE:To reduce the storage capacity of memory in a control device for setting the combustion of an engine in a predetermined condition, by storing a learning value of each engine cylinder in the memory in the form of a difference from that of a specific engine. CONSTITUTION:A final control amount determining means receives output signals from a basic control amount determined means, a feedback compensating amount determining means for each engine cylinder, a learning value storage means for a specific engine cylinder and learning value storage means for other engine cylinders, and delivers a control signal to an engine combustion control means (an ignition device and a fuel injection device) to control the burning condition of the engine. Since the differences in knocking limitation among the engine cylinders are slight, a learning compensating value for the specific engine cylinder is directly stored in memory while a learning map exhibiting a learning value for every operating range has a storage capacity of two bytes for the specific engine cylinder but of one byte for every other engine cylinder. Therefore, the storage capacity is reduce as a whole, thereby it is possible to aim at reducing the cost of the engine control device, at making the same lightweight and so forth.

Title: Video signal reproducing device
Inventor: MATSUO YASUTOSHI
IPC: H04N5/93
Filed: 1986-12-09
Abstract: PURPOSE:To surely prevent a malfunction and to attain stable mode discrimination even at special reproduction by providing a means fixing a discrimination mode of a mode discrimination means to the discrimination mode at the preceding reproduction. CONSTITUTION:At the special reproduction, a normal reproduction flag coming to an input terminal 18 goes to a low level. Thus, an AND circuit 17 is closed to block the passing of an edge detection pulse from a monostable multivibrator 16. Since no clock pulse comes to the clock terminal of a D flip-flop 11 during the special reproduction, the D flip-flop 11 holes the mode discrimination signal at the preceding normal reproduction. Thus, a switch circuit 21 is fixed to the connection mode at the mode discrimination at the normal reproduction just before the special reproduction. Thus, the mode discrimination is not malfunctioned even at the special reproduction.
