Title: Idle rotation control method for internal combustion engine
Inventor: TAKEDA MASAO
IPC: F02D41/22
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To restrain sudden start and to enable very low speed traveling by stopping the supply of fuel to one arbitrary cylinder when the idle operation is released in the condition where the number of times of fuel supply stop exceeds a designated number of times during idle operation.

When the counted number of times is above a designated number of time, it is detected that a mechanism for controlling the idle rotation including an actuator 116 causes failure for some reason, and stops in such a position to pass air above a certain quantity of air. In such a state, an accelerator pedal is actuated to turn off an idle switch 116d, and traveling is performed at a speed below a designated speed, the supply of fuel to an arbitrary cylinder is stopped. Thus, the generation torque of an engine is lowered to prevent overoperation of engine rotation and sudden start.

Title: Evaluating method of weldability of magnetic steel sheet for laminated iron core
Inventor: INOUE MASATAKA
IPC: G01B21/30
Filed: 1992-05-29
Abstract: PURPOSE:To evaluate exactly the escape property of gas at the time of welding of a magnetic steel sheet for a laminated iron core by determining an amplitude probability density distribution curve from a section curve of the surface of the steel sheet and by using as an index the volume of a part under a plane which passes the peak of the amplitude probability density distribution curve and is parallel to the surface of the sheet. CONSTITUTION:A section curve (a) is obtained by measuring the shape of the surface of a magnetic steel sheet by a roughness gage. An amplitude probability density distribution curve (b) is determined from the section curve (a). The amplitude probability density distribution curve shows the probability of an extracted section curve (a) being equal to a cut level from the uppermost top to the lowermost bottom when the cut level is taken in the extracted curve. Then, the average peak position of the amplitude probability density distribution curve (b) is determined and the volume V of a trough under a plane passing this peak position and being parallel to the surface of the sheet is calculated from three-dimensional information. In other words, the volume of the trough obtained by cutting the sheet along the horizontal plane passing the peak position is determined and weldability, i.e., permeability (escaping of gas) at the time of lamination welding, is evaluated by this volume value V.
