Patent JP-H02213224-A (JP)
Title: Phase comparator circuit using phase locked loop
Inventor: UMEZAKI YASUSHI
IPC: H04N19/196
Filed: 1989-02-13
Abstract: PURPOSE:To obtain an always stable sample clock output by using a VCO with high stability and slow tracking performance when the control voltage fluctuation of the VCO due to the input frequency fluctuation is small and using a VCO with low stability and high tracking performance when the control voltage fluctuation of the VCO due to the input frequency fluctuation is large so as to compare the phase. CONSTITUTION:When the fluctuation of a frequency 2fac is small, a 1st phase locked loop comprising of a phase comparator 1, a loop filter 2 and a VCO 4 applies the phase comparison. When the input frequency fac is largely fluctuated in the operation in the 1st phase locked loop, a voltage proportional to the deviated phase is generated from the phase comparator 1 and appears at a point A through a loop filter 2. When a voltage at the point A reaches a prescribed threshold level or over, a changeover switch 6 is switched and phase comparison is applied by a loop through the VCO 5. Although the stability of the VCO 5 is low in the loop, since the tracking performance is fast, the loop well tracks even a large voltage change, the phase deviation is converged and the voltage is below the threshold level.

Title: Radio call system
Inventor: NAKAMURA TAKAHARU
IPC: H04B7/26
Filed: 1988-02-16
Abstract: PURPOSE:To accurately transmit a complicated voice message by storing a personal identification code and a voice message in a base station by making a transmitter send them and taking out the voice message by sending the personal identification code to the base station by the receiver of a terminal when the transmitter calls the terminal. CONSTITUTION:When the transmitter calls a specific terminal 2, a call number is sent to the base station 1 as usual, however, the personal identification code and the voice message within a constant time are sent from the transmitter with the call number. And at the base station 1, the personal identification code and the voice message corresponding to the transmitter are stored in a memory device 11 in the base station 1. The terminal 2 called from the base station 1 receives the personal identification code, and receives the voice message stored in the memory device 11 by reading out according to the identification code. In such a way, the message of the transmitter can be transmitted directly to the receiver in voice.

Title: Air fuel ratio controller of internal combustion engine
Inventor: KIMURA EISUKE
IPC: F02D41/36
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To avoid generation of torque shock while preventing any worsening of emission at the time of switching an air/fuel ratio. SOLUTION: When a target air/fuel ratio is switched from RICH to LEAN, reduction of an engine torque following the changeover of the target air/fuel ratio is compensated by an increase in the engine torque following the increase in a sucked air quantity so as to prevent generation of torque shock by subjecting EACV (electronic air control valve) to step-by-step valve opening control as well as making sequential reduction control of fuel injection quantities to No. 1 to No. 4 cylinders at specific intervals. Then by correcting the target opening degree of EACV based upon the magnitude of the above-mentioned interval and the magnitude of the load on an internal combustion engine, generation of the above-mentioned torque shock is prevented more effectively.

IPC: B25J9/10
Filed: 1990-02-16
Abstract: PURPOSE:To compensate an arithmetic delay in a dynamic robot control method by showing the characteristic of a machine system in a state equation of a discrete time system and estimating the position and the moving speed of a robot. CONSTITUTION:In a dynamic robot control method, an arithmetic part 7 of a feedback circuit which calculates the state equation of a discrete time system estimates the position and the moving speed of a robot in the next sampling cycle based on the control output torque tau and a position/speed input signal (x) which are updated in each sampling cycle. Then the torque is calculated from the signal (x) of the (k + 1)-th sampling cycle estimated in the k-th sampling cycle as well as the target track of the same sampling cycle. The calculated torque tau is outputted in the (k + 1)-th sampling cycle. Thus it is possible to correct an arithmetic delay and to improve the deterioration of accuracy for a controller applying a microprocessor.

Abstract: PURPOSE:To produce the aq. solvent having an antimicrobial property to various kinds of microorganisms and to effectively use this solvent as water for preservation and water to be added to food and medical goods by impressing high voltage pulses to the surface of an aq. solvent, such as distilled water or deionized water. CONSTITUTION:High-voltage pulses are impressed to the surface of the aq. solvent, such as distilled water or deionized water. For example, the high-voltage pulses are impressed for 30 minutes at 20KV pulse voltage, 1mus pulse width and 1000Hz frequency to the deionized water 3 in the position apart by 5mm from the liquid surface. The antimicrobial aq. solvent obtd. in such a manner has the antimicrobial property to various kinds of the microorganisms. For example, the aq. solvent suppresses the growth of cells, such as spore bacteria, coliform bacilli and Eunycetes, such as ferment, or has the antimicrobial activity thereon. For example, the antimicrobial aq. solvent obtd. by impressing the high-voltage pulses to the deionized water in an argon atmosphere hardly allows the propagation of the microorganisms and is, therefore, effectively utilizable as the water for preservation and can prevent the contamination with the microorganisms by being added to the food and medical goods.

Abstract: PURPOSE:To prevent a car slip control device from malfunctioning by furnishing a power supply monitor to monitor the power supply for associated control devices, and equipping a control means to prohibit braking oil pressure, engine torque control, and failure sensing when the said power supply for associated control devices is put off. CONSTITUTION:When a power supply monitoring means 7 senses that a power supply for associated control devices is put off, the output from this sensing causes a control prohibiting means 8 to prohibit the braking oil pressure for a brake oil pressure control means 3, and prohibits engine torque control for an engine torque control means 5, and also prohibits failure sensing of the associated control devices for a failure sensing means 6. Thereby malfunction and erroneous sensing of failure are precluded owing to difference in the power supply between a slip control device concerned and the associated control devices.
