Abstract: PURPOSE: To establish a detecting method wherein an error is not caused in the formation of an average number value of revolution when noise pulse are generated, by forming an average number of revolution by weighting each segment number value of revolution from many segment number values of revolution. CONSTITUTION: A segment wheel is coupled to the shaft of an internal combustion engine and has many segments on the peripheral surface, and detected by a sensor like a hole sensor, and the number of revolution is obtained. A signal outputted from such a sensor is segment number values of revolution NS (ν-2), NS(ν-1), NS(ν), NS(ν+1)..., and turns to the input values of a number of revolution processing equipment. As the output of the equipment processing the number of revolution, the actual number of revolution NA(ν) at an actual time point of (ν) is obtained. In order to detect the actual number of revolution at the time point (ν), a formula is used. That is, the number of revolution NA can be obtained from the sum of many individual average number values NS of revolution which are weighted by the respective coefficients.  The coefficients A, B, C are determined from the following condition; when a frequency is low, an amplification factor is set as 1, the formula shows the average value, and the phase lead at a specific frequency becomes equal to a specified value.

Title: Detecting method for chamber inside moving object and device thereof
Inventor: NAGASE HIROSHI
IPC: F16K51/02
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To improve detection sensitivity for a moving object by applying an opposing magnetic field bias to a magnetic field from a magnet when magnetism from the magnet arranged in the moving object is detected by means of a lead switch arranged on the outside of a chamber. SOLUTION: A moving object 1 inside a chamber 3 is moved so as to be positioned to an opening time position B from a closing time position A, and the first magnet 2 is opposed to the second magnet 10. A magnetic field of the second magnet 10 works as an opposing magnetic field bias toward a magnetic field of the first magnet 2, and a magnetism flux is concentrated in a lead switch 4. As a magnetic member case for the lead switch 4 is removed, concentration of the magnetic flux to the lead switch 4 is intensified greatly. High sensitivity detection can be carried out by means of the lead switch 4, and the opening time position B for the moving body 1 can be detected. The sensitivity of detection can be increased as the second magnet 10 is brought closer to the lead switch 4.
