Title: Inter-cylinder air-fuel ratio dispersion abnormality detection device for multi-cylinder type internal combustion engine
Inventor: ODA SUMIHISA
IPC: F02D45/00
Filed: 2012-10-03
Abstract: PROBLEM TO BE SOLVED: To restrict a detection error caused by product dispersion of timing rotors to improve detection accuracy.SOLUTION: An inter-cylinder air-fuel ratio imbalance is determined on the basis of a difference Δω of crank angle speeds detected at each of at least one set of opposing cylinders belonging to banks different from each other and having crank angles different by 360°. In the case that the difference Δω is calculated in imbalance determination due to the fact that air-fuel ratio feedback processing for controlling a fuel injection quantity is performed for every bank, i.e. cylinder group, there occurs a possibility that in regard to opposing cylinders of other cylinders belonging to the same bank as that of the cylinders where imbalance is generated, it is wrongly decided as abnormal. In view of the foregoing, for the opposing cylinders of other cylinders belonging to the same bank as that of the cylinder where the crank angle speed is most different from a standard value, an index value is corrected to improve combustion (for example, the crank angle speed increasing side).

Title: Secondary battery cathode and manufacturing method thereof and nonaqueous secondary battery
Inventor: OSHIMA HIROKI
IPC: H01M4/139
Filed: 2012-10-11
Abstract: PROBLEM TO BE SOLVED: To provide a cathode for a nonaqueous secondary battery capable of enduring high voltage drive and eliminating a possibility of thermal runaway.SOLUTION: A surface of a cathode active material layer opposite to a side to which a current collector was bonded was covered with a porous film having through-holes with an average hole diameter of 80 nm to 2 μm. This porous film transmits ions such as lithium ions easily, but does not transmit an electrolyte easily. Therefore, reaction between the cathode active material and the electrolyte can be restrained, making it possible to prevent thermal runaway from occurring even under severe conditions such as a nail penetration test in high voltage drive. Furthermore, since decomposition of the electrolyte can also be prevented, deterioration of battery characteristics in high voltage drive can be prevented.
