Inventor: TAKEDA YUJI
IPC: F02P5/15
Filed: 1984-10-08
Abstract: PURPOSE:To improve the control accuracy by calculating the average value of actual rotation of engine at the time point when the actual idle rotation has approached to target rotation than controlling the ignition timing on the basis of the difference between said average value and the actual engine rotation. CONSTITUTION:When operating an internal-combustion engine 20, an electronic control circuit 44 will first calculate the actual engine rotation NE on the basis of the output from crank angle sensor 48 then calculate Q/NE on the basis of NE and the fuel flow flow Q to be operated with correspondence to the operating condition. Under idling where an idle switch 10 is turned off, the average ignition timing lead angle is set to a referential level. Upon detection that NE has reached within the target level range, control is started while employing NE at that time as the initial target level thus to calculate the average level of NE or NEn. Then the ignition timing lead angle is controlled on the basis on NEn and NE thus to control the engine rotation.

Title: Method and apparatus for detecting step-out of stepping- motor meter
Inventor: IIDA OSAMU
IPC: H02P8/38
Filed: 1998-07-27
Abstract: PROBLEM TO BE SOLVED: To reliably detect the step-out of a stepping motor which is used under high-temperature environment and in a very narrow space, by detecting the rotation of the stepping motor with a rotation detector of an absolute posi tion detecting type. SOLUTION: A rotation detector 30 for detecting an absolute position normally has a lead 39 extending from its body, and signals need to be transmitted up to a converter by connecting an extension cable 56 to the lead 39. Here, a heat-resistant lead 39 is connected to the heat-resistant extension cable 56 at a connection part 58 inside a casing 50. This is due to the fact that the lead 39 is not of specifications sufficiently durable to external environment but that it is required to be contained inside the casing 50. Also, the connection part 58 is completely sealed with a high-temperature resistant adhesive. This is for preventing the occurrence of insulation failures in the connection part 58, when vapor infiltrates to the inside of the casing 50.
