Title: Fault detecting apparatus for engine
Inventor: ICHIKAWA AKIRA
IPC: G01M15/04
Filed: 1990-02-16
Abstract: PURPOSE:To make it possible to detect a defective cylinder even for a multiple-cylinder engine using a crank-angle sensor for the small number of pulses by dividing one ignition period into two rotary angles, and inspecting the defective cylinder in response to the times of the rotary angles corresponding to the respective rotary angles. CONSTITUTION:One ignition period is divided into two angles of the first rotary angle and the second rotary angles at a specified angular interval with a rotary-angle detecting means 1 and the angles are detected. Then, the time in response to the first rotary angle and the time in response to the second rotary angle are detected in a rotary-angle-time detecting means 2. The abnormality of the engine is detected in correspondence with the first rotary angle time and the second rotary angle time in an abnormality detecting means 3 at the next stage. Since the abnormal cylinder is detected based on the rotary angle time, the abnormal cylinder can be detected even for the faults on the secondary side of an ignition coil and in a fuel system. Since one-ignition period is divided into the two angles of the rotary angles having the large change in rotating speed and the rotary angle having the small change and the abnormal cylinder is detected in response to the corresponding rotary angle times, this apparatus can be applied to an engine using a crank-angle sensor for a small number of pulses.

Filed: 1987-02-23
Abstract: PURPOSE:To wind a conductor exactly and systematically around a fine core, by holding the core inclinedly in a surface which is perpendicular to a transfer passage of the conductor and parallel to breadth of the core. CONSTITUTION:A conductor 1B is wound around a conductor winding part 4 of a core 2 in a VTR magnetic head.

Initially when a winding process starts, the core 2 is held inclinedly in the direction of an arrow 61 in a surface 60 which is perpendicular to transfer passage of the conductor and parallel to breadth of the core 2. When the winding process advances up to the upside of a wound part 4, the core 2 is held inclinedly in the direction of an arrow 62 in the surface 60 while a center 57 of the window 3 serves as a center (as shown in a figure.) Thereupon, the core 1B is wound exactly and systematically around the winding part 4, and so the winding around the part 5 except for the winding part 4 can be avoided.
