Title: Automatic frequency controller
Inventor: KAWABATA TAKASHI
IPC: H03L7/093
Filed: 1991-08-28
Abstract: PURPOSE:To implement demodulation able to cope with a large frequency fluctuation in mobile body communication or the like while keeping noise immunity by using an output of the automatic frequency controller for an input to a narrow band demodulator. CONSTITUTION:A complex base band signal including a frequency error is inputted to an input terminal 1. A 1st multiplier 5, a 1st VCO 9, a phase detector 7 and a loop filter 8 form a broad band PLL demodulator 13. A band width of the filter 8 is very large, the noise immunity is low but no reception signal is passed there through. The output of the filter 8 is branched to pass through an LPF 12, a noise component is compressed and the result is used for a control signal of a VCO 10. The output of the VCO 10 is inputted to a complex multiplier 6. On the other hand, the input branched just after an input terminal 1 is inputted to the multiplier 6 via a delay device 11 whose delay characteristic is equal to that of the LPF 12 and outputted to a terminal 2. The complex base band signal in which the frequency fluctuation of the input signal is absorbed and the frequency error is reduced is obtained as the output and the output is suitably fed to a narrow band demodulator 3.

Title: Controller for reactive power compensation device
Inventor: YAMAMURA HIDEKI
IPC: H02J3/18
Filed: 1991-08-28
Abstract: PURPOSE:To control TCT with high precision without being affected by higher harmonics by generating a reference voltage signal as a fundamental wave by a converter by utilizing the power source synchronizing signal of a PLL circuit and extracting a load current signal by a band-pass filter without any phase delay. CONSTITUTION:The converter 19 has a storage device such as a ROM circuit stored with a sine waveform as numeric data and a D/A converter which converts digital data outputted from the storage device sequentially. When the power source synchronizing signal consisting of a zero-cross signal and specific-cycle clock pulses is outputted from the PLL circuit 14, the converter 19 reads the numeric data out in order according to the signal, performs D/A conversion, and outputs the reference voltage signal as the fundamental wave synchronized with a system voltage. Further, the band-pass filter 20 has a center frequency equal to that of the fundamental wave and removes unnecessary higher harmonics to pass the fundamental wave. Neither of the signals contains the higher harmonics and an ineffective signal QL is calculated from them, so high performance is obtained.

Title: Distortion quantum well type semiconductor laser
Inventor: ISHIKAWA MAKOTO
IPC: H01S5/00
Filed: 1993-09-02
Abstract: PURPOSE:To acquire a highly reliable 0.7 to 1.1mum distortion quantum well semiconductor laser in a high yield by readily selecting an element which operates stably for a long time by a simple screening process by making light emission stripe in the orientation <-110>. CONSTITUTION:After a dielectric film such as SiO2 is formed in an upper surface of a p-GaAs electrode layer 6, an about 3mum-wide mesa stripe is formed in the orientation <110> in a p-clad layer 4 by using photolithography and wet etching methods. Furthermore, an n-type semiconductor current block layer 5 is selectively formed in a light emission stripe side surface by using an MOVPE method. Since refraction factor of the current block layer 5 is thereby smaller than refraction factor of the p-clad layer 4, equivalent refraction factor of the light emission stripe 9 becomes high in comparison with a stripe side surface. As a result, light and current are confined in the light emission stripe layer 9 effectively and highly effective oscillation can be realized at a low threshold value.
