Title: Air-fuel ratio control device for multi-cylinder internal combustion engine
Inventor: MORI KOICHI
IPC: F02D41/06
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To quickly activate catalysts by providing a fuel quantity setting means which sets the quantity of fuel to be fed to specified cylinders less than the quantity of fuel to be fed to the other cylinder when the condition of engine operations is in a specified range, and thereby limiting the inflow of fresh air into the other cylinder when the quantity of fuel to be fed to the specified cylinders is set less than the quantity of fuel to be fed to the other cylinders. SOLUTION: In the case of a four cylinder engine, for example, a second through a fourth cylinders 16-2 through 16-4 are assigned as specified cylinders, a first cylinder 16-1 is assigned as the other cylinder, and as for the first cylinder 16-1, an air-fuel ratio is set richer than the specified cylinders. Besides, a closing valve 17 provided with a cut-out for accelerating the flow speed of exhaust gas, or giving directivity, is provided for the exhaust manifold of the first cylinder 16-1 as a fresh air limiting means so as to be opened/closed by an actuator 18.  The aforesaid actuator 18 is drivingly controlled by negative pressure which is applied through a change-over valve 20 controlled by a control unit 7, so as to allow the introduction of fresh air to the rich cylinder to be limited when the engine is operated while an air-fuel ratio for the specified cylinders is made lean, and an air-fuel ratio for the other cylinder is made rich at the time of engine cooling operations.

Title: Measuring method for contact potential difference of powder
Inventor: ITAKURA TAKAYUKI
IPC: C09D5/03
Filed: 1994-03-08
Abstract: PURPOSE:To efficiently measure true contact potential difference of a powder, particularly a polymer powder, within a short time by removing static charge of the powder by AC corona discharge in the state that the powder is filled in a laminar state in a measuring electrode cell, opposing the cell to a vibration electrode, and measuring the potential difference of the powder. CONSTITUTION:Before measurement of contact potential difference of a powder, particularly a polymer powder, the powder is subjected to AC corona-discharge to be destaticized. Powder sample 1 is filled in a laminar state in measuring electrode cells 2, 3, and subjected to AC corona discharge. Thus, the potential of the powder layer can be reduced to 0 or substantially 0 without adverse influence to the true contact potential difference between the powder to be measured and metal. A time required for measuring the difference itself is several minutes, and a time for a preparatory operation necessary for removing the static discharge may also be about 5-10min. Further, since an operation for the removing static charge may be a simple vapor exposure treatment, the measurement of the true contact potential difference of the powder can be efficiently executed within a short time.
