Title: Four-wheel steering device
Inventor: HIRAI TOSHIRO
IPC: B62D6/00
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To sufficiently precisely detect an abnormal condition quickly while setting a dead zone threshold value low even when two steering angle sensors for feedback control of a rear steering angle to a target steering angle are arranged. SOLUTION: Two rear wheel steering angle sensors 38, 39 are arranged coaxially in the position in which a rotation angle of an electric motor 22 in an actuator 1 is detected. A deviation ΔδR1 between an actual rear wheel turning angel δR1 detected by means of one rear steering angle sensor 38 and a target steering angle value δ*R is computed. On the other hand, a deviation ΔδR2 between an actual rear wheel turning angle δR2 detected by means of the other rear wheel steering angle sensor 39 and the target steering angle value δ*R is computed.  If either of absolute values of the deviations |ΔδR1 |, |ΔδR2 | is determined to be the dead zone threshold value α1 , which is set at the predetermine value, or more, it is determined that an abnormal condition is caused in a feedback control system including the rear wheel steering angle sensors 38, 39 from the actuator 1.

Abstract: PURPOSE:To improve the sensitivity and the efficiency by arranging a boundary between the control electrode region and the principal electrode region of low impurity concentration on the surface of the light accepting side of the cell and occupying the principal part of the light accepting surface with the principal electrode region of low impurity concentration. CONSTITUTION:An n<-> epitaxial layer 101 is formed on an n-type silicon substrate 1 and the photosensor cells which are isolated electrically by an element isolation region 2 is formed in that layer. Each photosensor cell comprises a base region 102 and an n<+> emitter region 103 in a part of the n<-> epitaxial layer 101 which is the collector region of a bipolar transistor. The base region 102 faces a capacitor electrode 105 through an oxide film 104 and forms a capacitor. Accordingly, under the initial conditions that an n<-> epitaxial layer 101 which is a collector is biased into positive potential and the p-base region 102 into negative potential, a depletion layer is formed also in the light-accepting surface part of the n<-> epitaxial layer 101 so that the sensitivity increases.

Filed: 1983-06-22
Abstract: PURPOSE:To obtain a metal vapor discharge lamp with the low starting voltage and excellent light output life performance by providing a translucent film to prevent the reaction between metal halogenide and a quartz tube wall on the inner surface of a luminous tube except one portion. CONSTITUTION:Luminous metal halogenide, e.g., scandium, sodium, is sealed in a luminous tube 1 made of quartz together with a proper quantity of mercury and rare gas. In addition, a translucent film 3 mainly composed of aluminum phosphate, titanium oxide, aluminum oxide, etc. is formed on the inner surface of the luminous tube 1 made of quartz. A notch 4 to pass impure gas is provided at one portion of this translucent film 3. Accordingly, the reaction between the metal halogenide and quartz tube wall is suppressed by the translucent protective film 3 formed on the inner surface of the luminous tube, on the other hand, the impure gas entering during production, etc. permeates and diffuses outside the luminous tube through the notch 4 to be adsorbed by a getter material 7, thereby the impure gas concentration in the luminous tube is reduced, the starting voltage is lowered, and the light output life performance is improved.
