Title: Optical element
Inventor: TAKESHITA TATSUYA
IPC: G02B6/12
Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To obtain the optical element which realizes nondependence of the gain on the polarization forming a group of active layers waveguide mode an active area. SOLUTION: A current blocking layer 3 is put nearby the center and active layers 1 are arranged on the right and left sides of this current stop layer 3. Each active layer 1 is, for example, 0.3μm thick and <=1μm, e.g. 0.5μm wide. The gain is generated when a current is impressed to the active layer 1, and the current is narrowed down by the blocking layers 3 and 6 and effectively impressed to the active layer 1. The active layers 1 are arranged on both the right and left sides of the blocking layer 3, so the light confinment coefficient can be made small as compared with that in the absence of the blocking layer 3. Further, the light confinment coefficient can be varied by adjusting the width of the blocking layer 3.  Consequently, the signal gain in TM mode and signal gain in TE mode can be made equivalent to each other and a gate type semiconductor optical switch with low polarization, a low working current, and a high gain can be obtained.

Title: Abnormality detecting method of power steering apparatus
Inventor: EBINA AKIMITSU
IPC: B62D6/00
Filed: 1989-07-17
Abstract: PURPOSE:To prevent a normal sensor from being erroneously judged as abnormal by sorting a plurality of signals for detecting abnormality to a first and a second kinds of signals, and processing said two kinds of signals in a different manner. CONSTITUTION:It is detected by a solenoid disconnection sensor 1a whether a solenoid is disconnected. If the solenoid is disconnected, a flag (b) in a memory of a controller 6 is set to be 1. It is detected by a solenoid short sensor 1b whether the solenoid is shortcircuited. If the solenoid is shortcircuited, a flag (c) in the memory is turned 1. Once the flags (b),(c) are turned 1, they never become 0 henceforward. Then, the abnormality as to a steering angle signal, an engine signal and a vehicle speed signal is detected from sensors 1c-1e, respectively. Without abnormality, the flags (d)-(f) in the memory are turned 0. Therefore, so long as the signal abnormality continues,the flags (d)-(f) are maintained 1. However, once the signals become normal, the flags (d)-(f) are turned 0, and the signals are never judged as abnormal. Accordingly, the presence or absence of the abnormality of each sensor 1a-1e can be correctly detected.
