IPC: B62D7/14
Filed: 1993-08-06
Abstract: PURPOSE:To return an output rack to a neutral position in turning a motor shaft in time of something wrong with a rear-wheel steering system by installing a skew gear in a part of the motor shaft, and storing energy in a spiral spring in accord with a rotation of this transmitted gear. CONSTITUTION:When a brushless motor 4 is rotated, a motor shaft 9 is rotated as well, while a first worm 8 rotates, thereby transmitting its turning effort to a first worm wheel 7. In consequence, a pinion 6 rotates, while a shaft 1 moves in the axial direction via a rack 1a, and thereby rear wheels are steered. In this case, a second worm installed in a tip of the motor shaft 9 is rotated as decelerating it, whereby two pins 14 and 16 are made contact with each other, thereby rotating the shaft 15. In succession, a spiral spring 12 is wound, and energy is stored in this spring. Using this energy stored in this spring 12, the second worm wheel is rotated, and thereby the shaft 1 is returned to a neutral position.

Title: Incandescent lamp-type fluorescent lamp
Inventor: SUZUKI ATSUSHI
IPC: H01J61/72
Filed: 1983-10-21
Abstract: PURPOSE:To stabilize the electric discharge of an incandescent lamp-type fluorescent lamp during transition and suppress the flickering of the emission by adjusting the inner diameter of two curved inner tubes having phosphor films on their inner surfaces and the ratio of lamp voltage to power source voltage according to specified formulae. CONSTITUTION:In two curved inner tubes 5 and 5' having phosphor films 4 on their inner surfaces, for the same relative lamp voltage VL, the flickering of the emission is more suppressed as the inner diameters of the inner tubes 5 and 5' are larger. While, for the same inner diameter D of the inner tubes 5 and 5', the flickering of the emission is more suppressed as the relative lamp voltage is smaller. Accordingly, when the inner diameter of the inner tubes 5 and 5' is supposed to be D(mm.) and the ratio of lamp voltage to power source voltage is supposed to be VL, D and VL are adjusted according to the formulae D>=9 and VL<=0.87D<2>-14.1D+110. By the means mentioned above, the potential gradient between the openings of the inner tubes 5 and 5' is decreased and the difference between the potential gradients of the inner tubes 5 and 5' is decreased. Accordingly, it is possible to stabilize the electric discharge of the lamp during transition and to prevent any flickering of the emission.
