Title: Optical signal transmission system
Inventor: FUJIMURA HIROSHI
IPC: H04B10/556
Filed: 1985-11-26
Abstract: PURPOSE:To set optimizingly the phase relation between a data signal and a timing signal by providing a phase adjusting function of the data signal and the timing signal. CONSTITUTION:A received synthesis optical signal is branched into two waves, an optical signal of reception data and a timing signal by a demultiplexer 6. An optoelectric converting circuit 7 converts the former optical signal into an electric signal of a reception data and converts the latter optical signal into an electric signal of the timing signal respectively. The amplifiers 8, 9 amplify both electric signals independently. A timing extraction circuit 10 extracts the timing signal from the output of the amplifier circuit 9 and gives the timing signal to a phase adjusting circuit 11. An identification circuit 12 identifies and recovers a reception data from an output of the amplifier circuit 8 by using an output timing of the phase adjusting circuit 11. The phase adjusting circuit 11 receives a data signal from the output of the amplifier 8 to apply phase control and when the reception signal is an RZ signal, the phase of the reception signal is discriminated by detecting the point of time at the change of the reception signal.

IPC: B60T8/44
Filed: 1990-10-05
Abstract: PURPOSE: To uniformize a flow of a fluid form a pump to a brake by connecting a partition chamber arranged in a return pipeline without being regulated irrespective of a position of a control valve, opening a reservoir to the atmospheric air, and communicating it with an operation chamber when a master cylinder does not operate. CONSTITUTION: When a brake pedal 4 is stepped on, a pressure formed in a master cylinder 2 is transmitted to wheel brakes 10, 11 through brake pipelines 7, 8 or pipelines 7, 9. When a wheel is almost locked, a pump 16 is driven, an outlet valve 14 is operated, and a pressure fluid flows into a reservoir 15 from the brake pipelines through a throttle 19 when a return pipe 13 is opened. A differential pressure is formed between the throttle 19 and partition chambers 21, 22, an operation piston 20 is moved to the right, and a pressure fluid from the brake 10 returns into the reservoir 15 through the return pipeline 13. Since the pump 16 receives atmospheric pressure from the reservoir 15 at all times, a discharge amount of the pump 16 becomes constant.

Abstract: PURPOSE:To protect an overcurrent rapidly with a simple structure by connecting a current detecting resistor in series with the cathode side of a GTO, and inserting a diode between the gate of a GTO turning OFF thyristor and the cathode of the GTO. CONSTITUTION:An overcurrent protecting circuit of a GTO1 omits an overcurrent detector, connects the first diode 31 between the cathode of the CTO1 and the gate of a thyristor 16, and connects the second diode 32 between a parallel circuit of a capacitor 15 and a resistor 14 provided at the collector of a transistor Q1 of a drive circuit 5' and the gate of the thyristor 16.

Abstract: PURPOSE:To enable constitution of a stable and robust control system as a means to vary the characteristics of the reduction pass filter of a turbulence compensating part according to a difference between the output of an object to be controlled and the output of a model. CONSTITUTION:During steering, a first subtractor (e) subtracts a steering angle prediction value from a steering angle prediction part (d) from a steering angle actual value from a steering angle sensor (c) and outputs an error signal responding to disturbance or the change in characteristics of an actuator. A compensator (f) inputs the error signal, and based on transmission characteristics obtained by multiplying transmission characteristics, having reduction pass characteristics, by the reverse transmission characteristics of a steering angle predicting part (d), a correction value of a steering angle command value is outputted. The correction value is subtracted from the steering angle command value by a second subtractor (g), a corrected command value is outputted to an actuator (b), and this operation causes a steering angle varying mechanism (a) to provide a steering angle for an auxiliary steering wheel. In which case, since reduction pass characteristics provided for the compensator (f) is varied by a reduction pass characteristic varying part (h) according to an error signal by means of which the output of an object to be controlled and the output of a model is represented, a stable and robust control system can be constituted.

Title: Sound model determining method for word
Inventor: AUBERT XAVIER LOUIS DR
IPC: G10L15/06
Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To accurately model a word containing at least one triphone which is not generated during a training period. SOLUTION: When a spoken text is recognized, the spoken text need to be made useful in the form of a series of reference values. The reference values are determined from a known text for the training period and characteristic values are taken out for a regular period. For the recognition period, those characteristic values are arrayed according to triphones 43 to form groups 40 to 41 or clusters. The groups 40 to 42 form the base of the reference values. When a recognition system includes an extremely large vocabulary, all triphones 43 are not generated for the training period if the text is inhibitively long.  To determine a reference value as to a word which contains ungenerated triphone 43, the ungenerated triphone 43 needs to be related to the groups 40 to 42, which are all tested to determine whether the same center phoneme as the triphone 43 to be related is present or not together with its left-side and right-side phonemes.
