Title: Optical modulator and integratation type optical modulator and photodetector as well as production thereof
Inventor: AJISAWA AKIRA
IPC: H01S5/026
Filed: 1989-12-27
Abstract: PURPOSE:To attain ultra-high-speed modulation and the widening of a frequency range and to improve a yield and uniformity by using a high-resistance semiconductor substrate and embedding a PIN structure optical waveguide with the high-resistance layer. CONSTITUTION:Striped means 69 having the pin structure in which an I layer of a low carrier concn. is formed as the semiconductor optical waveguide layer 66, the high-resistance layers 70 on both side faces of the striped means, and means for impressing electric fields to the semiconductor optical waveguide layer 66 are provided on the high-resistance semiconductor substrate 61. The inter-electrode distance is made longer than heretofore by using the high- resistance semiconductor substrate and the embedding structure of the semiconductor high- resistance layers. The wiring capacity and pad capacity are, therefore, decreased and the capacity over the entire part of the element is determined nearly by a junction capacity and the frequency range of the optical modulator is widened. The ultra-high-speed modulation as the integration type optical modulator is executed by having the PIN structure formed on the high-resistance substrate and embedded by the high-resistance layers. Thus, the ultra- high-speed modulation and the widening of the frequency range are possible in this way and the yield is improved.

Inventor: HARADA MOTOO
IPC: B62D101/00
Filed: 1992-12-21
Abstract: PURPOSE:To correctly detect the abnormality of an electric motor in an electric power steering. CONSTITUTION:A microcomputer 24 cuts off the supply of a driving current to an electric motor 17 only for the specified short time, and judges the motor 17 to be abnormal in the case of no fluctuation being generated to steering torque Ts detected by a torque sensor 22 before and after the cutoff of this driving current whereas judges the motor 17 to be normal in the case of fluctuation being generated. Accordingly, in the case of the motor 17 being out of operation due to mechanical lock or the like, the abnormality of the motor 17 is detected, but in the case of steering being out of operation due to front wheels FW1, FW2 hitting curbstones or the like, the motor 17 generates assist force opposed to reaction based on the elasticity of tires, so that the steering torque Ts is fluctuated before and after the cutoff of the driving current. The abnormality of the motor 17 is not thereby detected.

IPC: H01S1/02
Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To provide the rubidium atomic oscillator where its rising time is reduced by increasing an amplification factor for a photo detection signal at the rising. SOLUTION: A cavity containing a resonance cell which is filled with rubidium gas is stimulated by a microwave, a resonance light radiated from a rubidium lamp is made incident onto the resonance cell, a photodetector detects the passing light, and the oscillating frequency of microwave is controlled depending on the photodetection signal, to obtain a standard frequency signal in this rubidium atomic oscillator, which has a gain increase means 30 that increases the amplification factor of the photodetection signal at its rising. Thus, when a level of a photodetection signal at the rising is low, the level of the photodetection signal is increased. Since a frequency of an amplified detection signal of the rubidium atomic oscillator is locked and then the frequency is to be made stable, the rising time required for having the frequency made stable is reduced.
