Abstract: PROBLEM TO BE SOLVED: To lighten vibration due to a shimmy transmitted to a car body, and restrain driver's feeling from being hurted. SOLUTION: It is judged that a shimmy has taken place when a signal level of a specified frequency constituent (for example, 10 to 20 HZ) corresponding to shimmy of a stroke detection value θS from a rock stroke sensor 16, is in a level capable of being regarded as the shimmy, and furthermore, when the detected value V of vehicle speed by a vehicle speed sensor 14 is in a range of vehicle speed (70 to 130 km/h) coming shimmy into question, when a steering angle based on a stroke detection value θS is in a range of 0 deg.±10 deg., and when the vehicle is considered to have been in a straight running condition.  And when the shimmy takes place under a condition that the detected value T of steering torque is less than a reference value Tα, short circuiting an auxiliary steering motor 8 thereby allows reverse elector motive force to be generated due to the shimmy in the auxiliary steering motor 8, and the auxiliary steering motor 8 thereby acts as a load, for this reason, vibration transmitted to a steering wheel due to the shimmy, can thereby be restrained.

Title: Low-nox burner
Inventor: WANI SHIZUO
IPC: F23C99/00
Filed: 1990-07-31
Abstract: PURPOSE:To reduce the generation of NOx without interfering with the combustion efficiency and stabilize the combustion by providing a header in which fuel injection nozzles are arranged unevenly in a circle around the axis of the header. CONSTITUTION:A plurality of fuel injection nozzles formed in a header 1 include two having a larger bore. These nozzles are so arranged that, in the flaming regions formed on the right and the left of the center of the header, fuel is injected in excess of the average and hence produces a little surplus, whereas, in the flaming regions above and under the center, a surplus of air is produced. Therefore, downstream from the burner, the combustion produces a flame which is asymmetric with portions forming flaming regions oversupplied with fuel and the other portions, flaming regions oversupplied with air, that is, formation of a flame produced in part by concentrated combustion and in part by thin combustion. This decreases the average temperature of the flame and hence restrains the generation of NOx.
