Patent JP-H0992434-A (JP)
Title: Spark plug
Inventor: NAKANO TAMOTSU
IPC: H01T13/32
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To improve fuel consumption through the enhancement of ignition and combustion efficiencies so as to decrease contaminants in exhaust gas by making the end of an earth electrode branch off, and placing the inside corners of the branching ends in positions opposite to the outer edge of the end of a center electrode. SOLUTION: When a voltage is applied between the center electrode 4 and earth electrode 6 of a spark plug 1, a spark is produced in a spark gap 5 to ignite and burn mixed gases of fuel and air in a combustion chamber. In this case the spark is first produced stably since the end of each branching part 8, 9 of the electrodes 6. i.e., the inside corner of each branching end 8a, 9a, faces the outer edge of the end 4a of the electrode 4,. Flames produced by the spark diffuse radially into the combustion chamber in the direction of the plane of the spark gap 5 between the electrodes 4, 6 and through an opening 10 between the branching parts of the electrode 6. The time required for the flames to spread throughout the combustion chamber is thus reduced for increased combustion efficiency.

Title: Method for straightening metallic bar stock
Inventor: SATO HIROMITSU
IPC: B21D3/05
Filed: 1993-09-30
Abstract: PURPOSE:To provide a method in which the curl of a bar stock is accurately and easily straightened by a leveler. CONSTITUTION:Reference is made to the method where the curl of a bar stock is straightened by uncoiling a coiled bar stock W and putting it through the two sets of straightening rollers 4, 5. The space between the two sets of the straightening rollers 4, 5 is set to the size corresponding to the thickness of the bar stock by a control device 14. Then, the diameter of the coil of the bar stock is continuously detected; the size of the coil diameter thus detected is applied to the relation between the size of the coil diameter and the size of the curl of the bar stock by the control device; the size of the curl is obtained on the bar stock at the time of the detection; the size of the space between the two sets of the straightening rollers is determined by the control device, by which space the curl can be straightened based on the size of the curl of the bar stock; and, based on the value thus determined, the space is adjusted between the two sets of the straightening rollers.

IPC: B60W10/06
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To improve responsiveness of controlling action of a vehicle. SOLUTION: A target yaw rate γt of a car is computed based on a steering angle θ, etc., (S20). A target vehicular body speed Vdt is computed in a drift-out state (S30). A target vehicular body speed Vst is computed in a spin state (S40). A target vehicular body speed Vt is computed as a lower value of the target vehicular body speeds Vdt, Vst (S50). Deviation ΔV between the target vehicular body speed Vt and the actual vehicular body speed is computed (S60). An engine output torque adjustment rate ΔTe is computed based on the deviation ΔV of the vehicular speeds (S70). The engine output torque is varied according to the adjustment rate ΔTe for controlling the actual vehicular speed V to be the target vehicular speed Vt (S80, S90). It is thus possible to suppress the drift-out or spin state of the vehicle, and stabilize action of the vehicle.
