Abstract: An electronic device is configured to be wholly controlled by an engine unit. The engine unit includes a work memory for a CPU and a DRAM utilized as a cache memory for a data memory unit. The data memory unit has a sleep function for power saving. When a data read/write request is made under a sleep mode of the data memory unit, the engine unit decides whether or not the data read/write processing can be performed in the cache area of the DRAM and, if the engine unit decides that it can be performed, the read/write processing is performed in the cache area only of the DRAM without returning the data memory unit from its sleep mode.

Abstract: In an optical fiber connector (1), an outer member (2) holds a portion of an optical fiber (4A) remote from its connecting end which is connectable to a connecting end of a counterpart optical fiber. An aligning member (3) is held by the outer member so as to be movable along the optical fiber. The aligning member carries out positioning of the connecting end of the optical fiber. The aligning member is urged by a spring (5) in a direction to project from the outer member. When connecting the optical fiber to the counterpart optical fiber, the aligning member is moved in a direction opposite to the foregoing direction against an urging force applied by the spring so that the connecting end of the optical fiber is projected from the aligning member.

Abstract: An engine rotation speed during idle running is feedback controlled to a target rotation speed. A basic ignition timing is set based on the rotation speed during idle running, and the ignition timing is feedback corrected based on a difference between a target rotation speed and a measured rotation speed. This feedback correction process and other processes including the setting of the basic ignition timing are separated. A high response ignition timing feedback control is performed by advancing the measuring timing of the rotation speed to a point earlier than the correction timing by at least the processing time required to perform the feedback correction process, and preferably by a value near the processing time. A high response fuel injection amount feedback control may also be performed by a similar process.
