Title: Ignition timing controller of internal combustion engine
Inventor: OYA FUMIAKI
IPC: F02P5/15
Filed: 1988-05-26
Abstract: PURPOSE:To properly execute delay angle compensation at a cold time while maintaining good drivability by gradually performing advance angle compensation after delay angle compensation is applied to the ignition timing of engine according to octane value of fuel at the cold time after idling. CONSTITUTION:A judgement means M1 judges the octane value of fuel used for an internal combustion engine. A computing means M2 computes the ignition timing of internal combustion engine M3 according to the results of judgement of means M1. In this case, the temp. and idling are respectively detected with detection means M4, M5. A compensation means M6 serves to correct the ignition timing at the cold time of the engine M3. Namely, at the cold time after idling, the ignition timing for high octane value fuel is largely delay-angle compensated according to the temp. of engine M3, and the ignition timing for normal octane value fuel is delay-angle compensated minutely, and then the timing is gradually advance compensated.

Title: Noise filter
Inventor: MURAKAMI YUUICHI
IPC: H01F3/10
Filed: 1979-10-09
Abstract: PURPOSE:To use few magnetic core material and bobbin winding, and miniaturize a case by a method wherein a pair of U-shaped magnetic cores are formed in butting shapes so that both ends of the leg parts cross at right angles mutually in the noise filter having a two stage filter function. CONSTITUTION:The U-shaped magnetic cores 5, 5' are combined to ensure that the end surfaces of leg parts cross at right angles mutually and opening ends are mutually bridged. Each leg part of the magnetic core 5 is formed respectively so that winding 6, 7 is the same number of winding and winding polarity is inverted. Winding 6', 7' is each made up similarly to each leg portion of the magnetic core 5', and further the winding 6 and 6' and the winding 7 and 7' are connected in series respectively. Here, magnetic flux generated at the magnetic core 5 by means of the winding 6, 7 and the magnetic flux generated at the magnetic core 5' by means of the winding 6', 7' each cross at right angles in the magnetic cores as shown in broken lines. Consequently, mutually independent choke coils are formed in the magnetic cores 5, 5', and the filter by constitution at two stages is realized by means of one composite choke coil. Thus, the case is miniaturized because the magnetic core material is decreased and the bobbin windings can be used.
