Title: Compression system for buffer memory
Inventor: KOMINATO MOTOYUKI
IPC: G06F5/06
Filed: 1981-03-25
Abstract: PURPOSE: To reduce the capacity of a buffer memory, by compressing also a space between characters with a compression code.  
     CONSTITUTION: A character pattern decomposed into dots is stored in row unit or page unit and dot information is outputted while scanning trnsversally and sequentially. In such a character output device, when a character code is transmitted, an input control section 1 transmits it to a character generating section 2, a pattern corresponding to this character code is generated from the character generating section 2 and given to a compression circuit 7, converted into the compression code and stored in a buffer memory 8. Since the said compression circuit 7 not only compresses the character pattern but also compresses the space pattern transmitted from the input control circuit 1, the amount of information stored in the buffer memory 8 is remarkably reduced.

Filed: 1992-02-28
Abstract: PURPOSE:To prevent an erroneous detection of abnormal condition in advance by eliminating influence of non-synchronous injection and fluctuation of the rotational number of an internal combustion engine just before detection of abnormal condition. CONSTITUTION:In an engine 1 provided with a secondary air supplying device 12 when setting up of abnormal detecting condition is judged by an ECU 30 on the basis of the value detected by each sensor, injectors 6A to 6D are driven so as to detect abnormal condition in the secondary air supplying device 12, and thereby, a base air fuel ratio is set in rich condition forcibly. In the ECU 30, abnormal or normal condition is judged on the basis of an exhaust air-fuel ratio at this time. In the ECU 30, when non-synchronous injection is carried out, the initial value of an erroneous diagnosis preventing counter is set, and count-down is started from the initial value. Judgement of abnormal or normal condition on the basis of the exhaust air fuel ratio is inhibited by the ECU 30 only for a period until the result of count-down is just going to reach a reference value. As a result, the exhaust air fuel ratio not be placed in rich condition by influence of non-cynchronous injection which is carried out just before, in the case when abnormal condition is detected.
