Title: Ignition timing control device for internal combustion engine
Inventor: AKISHINO KATSUO
IPC: F02P5/152
Filed: 1987-02-27
Abstract: PURPOSE:To suppress the occurrence of knocking by changing the comparison level voltage with an ECU to remove the noise component other than the knocking signal from the output of the vibration acceleration sensor of an engine and performing the ignition timing control in response to the knocking signal. CONSTITUTION:A gate timing controller 4 is operated by outputs of a phase shifter 8 and an angle sensor 13, and an analog gate 3 is closed for a preset period to remove the ignition noise contained in the detected signal of an acceleration sensor 1 and the vibration noise of an intake valve and an exhaust valve. A noise level detector 5 changes and generates the comparison level voltage value with the signal from an ECU 5a, and this voltage is compared with the output value of the analog gate 3 by a comparator 6. When no knocking occurs, no output is generated from the comparator 6, and the phase shifter 8 is not operated. When knocking occurs, output pulses are generated by the comparator 6, the phase of the standard ignition signal is delayed by the output of the phase shifter 8 in response to the integrated voltage to obtain state free of knocking.

Abstract: PURPOSE: To inhibit the leap of a helical cable in a housing at a time when it receives vibrations, by packing a thin absorption strip having a sliding face, and having a width at least two times that of a flat cable, between the adjacent layers of the flat cable. CONSTITUTION: A thin absorption strip 15 having a sliding face, and having a width at least two times that of a flat cable 13, is packed between the adjacent layers of the cable 13 forming a helical cable 11.

Abstract: PURPOSE:To prevent the degradation of copying quality caused by the patial electrification history of a photosensitive body due to local electrification thereto on a paper edge part by changing over the grid voltage of a pretransfer scorotron to a voltage different in an image part and the paper edge part. CONSTITUTION:A scorotron for pretransfer processing (PTC) 5 performing the electrification of a polarity different from that of a transfer corotron 7 is provided and the absolute value of the grid voltage of the PTC 5 is made larger than that when the image region passes, at the timing of when the tailing edge of the image region or its leading and tailing edges pass the PTC 5. Therefore, on the tailing edge part of a paper sheet or its leading and tailing edge parts, a potential by the electrification of the photosensitive body 1 is previously set higher before the paper sheet is rushed into a transfer region, so that the electrification history to the photosensitive body 1 caused by spark discharge occurring on the edge part of the paper can be prevented. Since a static eliminating corotron 10 is dispensed and it is unnecessary that a part of a dielectric film is conductive, a defect that a copy has a streaky defect can be removed for any sizes of the paper.
