Filed: 1986-09-11
Abstract: PURPOSE:To stop power supply to the load quickly, by setting the third transistor 'ON' and the first transistor quickly 'OFF' when a control terminal is on a low level. CONSTITUTION:A switching power device connects a series circuit of the primary winding 10 of a transformer 4 and a transistor (hereinafter referred to an Tr) 5 between input terminals. A control winding 9 is connected to the base of the Tr 5 and the output is taken out of the secondary winding 11 of a transformer 4 through rectification and smoothing circuits 12-13 and output terminals 14-15. At this moment, resistance 17-18 are connected between input terminals 1-3 and their partial potential point is connected to the base of a Tr 19. A Tr 20 is connected between the base of the Tr 5 and the input terminal 3, to the base of which the partial potential across output terminals 14-15 is impressed through a resistance 21. Thus, when a control terminal 2 gets to L level, the Tr 19 is OFF and the Tr 20 ON, so that the Tr 5 can quickly be OFF and the output voltage can be set 0 immediately.

Abstract: PURPOSE:To achieve highly accurate assembly with ease and to obtain a better detection sensitivity by setting a length in a Z axis direction so that a rotation angle of a light beam transmitted through an electrooptical crystal reaches a specified value. CONSTITUTION:A pair of electrodes 29 is formed on the side in the Y axis direction of an electrooptical crystal 21 and the dimensions L in the Z axis direction of the crystal 21 are set to satisfy theta=pi/2).n when the rotation angle of a light beam transmitted through the crystal 21 is theta radian, wherein (n) is a positive integer. A voltage E is applied between the electrodes 29 and works in the Y axis direction of the crystal 21. On the other hand, the light beam is transmitted through the crystal 21 in the Z axis direction by way of an optical fiber 22 and extracted with an optical fiber 28 to determine the voltage E by measuring an optical change. Light is transmitted in the Z axis direction and when a voltage added in the Y axis direction, a refractive index ellipsoid inclines by pi/2 radian. Thus, the inclination of the ellipsoid can be cancelled by setting the Z axis dimensions L of the crystal 2 as mentioned above thereby obtaining better characteristic with arrangement of optical parts on a two-dimensional plane.

Title: Variable steering angle ratio steering gear for vehicle
Inventor: TOKUNAGA HIROYUKI
IPC: B62D5/04
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To favorably prevent any possible oversteering in course of steerage from occurring. SOLUTION: Because of such a fact that a steering angle ratio is controlled according to the conditions of a vehicle to the road conditions given such as a road surface μ, a lateral force duty cycle, an alteration to a car lane or the like, for example, in the case where a vehicle travels in the state of a low road surface μ, a steering angle ratio is enlarged, and thereby such a fear that if steerage takes place in keeping up an ordinary steering angle ratio steered intact, a steering wheel is oversteered so much is solvable. In addition, the steering angle ratio is increased according to an increment of the lateral force duty cycle in the steering wheel, and thereby any oversteering is obviated, and further the steering angle ratio is enlarged according to an increase of ratio in a lateral travel predicted value after the elapse of specified time to the maximum lateral travel of up to the car lane, and the steering angle ratio is also increased according to a reduction in a deviation between the lateral travel predicted value and the lateral travel measured value after the elapse of specified time, whereby the vehicle is preventable from deviating from the car lane, and thus a burden on a driver from the viewpoint of car control is reducible.

Abstract: PURPOSE:To judge whether a beam diameter varying mechanism operates normally or not without adding another mechanism, such as sensor, to this mechanism and to prevent the degradation in image quality by the abnormal operation thereof by comparing the intensities of the incident beams on a synchronous detecting unit before and after changing over the beam diameter by a beam diameter varying means.

The synchronous light powder is equal to the beam power arriving at a photosensitive body and does not change with the dpi. Then, the synchronizing light powers before and after the width of the aperture slit is changed by an aperture controller 31 are compared and if these powders are not equal, the abnormality is displayed on an operation panel as the changeover error of the aperture slit in the beam diameter varying mechanism. The accuracy of the checking is improved by executing the comparison and decision plural times in such a case.
