Title: Frequency converter
Inventor: YAMABAYASHI MASAAKI
IPC: H03K5/00
Filed: 1988-06-14
Abstract: PURPOSE:To eliminate a pulse jitter in an output signal without deteriorating the pull-in characteristic of a PLL by generating a sawtooth wave included in an output of a loop filter constituting a PLL similar to a sawtooth wave separately and using the sawtooth wave generated separately so as to erase the sawtooth wave component in the output of the loop filter. CONSTITUTION:The converter consists of a pulse insertion circuit 2, a phase comparator 4, a loop filter 5, a voltage controlled oscillator(VCO) 7, a counter 10, a digital analog converter 11 and a differential amplifier 12. Then a sawtooth wave similar to the sawtooth wave appearing at the output of the loop filter constituting the PLL(Phase locked loop) is generated separately and the sawtooth wave generated separately cancels the sawtooth waveform included in the output of the loop filter 5. Thus, pulse jitter in the output signal is eliminated without sacrificing the locking range to the PLL.

Title: Device for preventing vehicle drive while dozing
Inventor: DAIMON NOBUO
IPC: B60H1/00
Filed: 1993-06-16
Abstract: PURPOSE:To provide an inexpensive for preventing vehicle driving while dozing, which does not hurt driver's feeling but is effective to prevent vehicle driving while dozing by extending the due time of a warning medium in proportion to time having elapsed since a vehicle driving while dozing prevention switch was turned on, and concurrently shortening the due interval of the warning medium in reverse proportion to time having elapsed. CONSTITUTION:A CPU 8 allows time (t1) allocated for blasting cool air by a timer 6 to be reset so as to be started, when the CPU judges that a switch 5 has been tuned on by reading the output of the vehicle driving while dozing prevention switch 5. A signal 81 for quick cooling is outputted to a control means, if the first duration time (t1) allocated for blasting cool air is within a specified duration time, an evaporator allows cool air which is cooled the most, to be blasted out of a spit hole toward a driver. And the output of the signal 81 for quick cooling is suspended, if it is judged that the first duration time for blasting cool air exceeds a specified duration time. In this case, the time allocated for a cool air blasting timer 6 is made longer as the number of times for air blasting is increased, on the contrary, time (t2) allocated for a cool air blasting timer 7 is made shorter.

Title: Controller for activated sludge process
Inventor: WATANABE SHOJI
IPC: C02F3/12
Filed: 1988-06-15
Abstract: PURPOSE:To keep activated sludge having an excellent settling property for a long period stable by monitoring inflowing sewage and the settling property, and using the result as the operational barometer. CONSTITUTION:The flow rate of the sewage 3 flowing into an aeration tank 1 is continuously measured by a flowmeter 11, and the amt. of inflowing sewage per day is integrated by an arithmetic circuit 20. The deviation in the flow rate between the inflowing sewage amt. per day and the reference inflowing water amt. from a setting circuit 24 is obtained by a discriminating circuit 22, and the desired operational value of the aeration tank 1 is set by a setting circuit 28 based on the mean flow rate deviation for the past specified period. Meanwhile, the settling property of activated sludge per day is measured by a sludge settling meter 15 and a sludge densitometer 16. When the settling property for a specified period does not reach the reference value, the target operational value is not changed, and the actual value is maintained. Since the change in the flow rate for a specified period and the settling property are used as the operational target in this way, the deterioration in the settling property is controlled, and the time required for the restoration from the deteriorated conditions is reduced.

Abstract: PURPOSE: To significantly reduce noise due to PWM control from a motor. CONSTITUTION: Pulses with the frequency corresponding to a frequency pattern stored in a frequency pattern storage 10 are output from a PWM controller 12. The frequency pattern is, for example, a pattern which changes the frequency with time. A switching transistor 15 performs switching by using this pulse. Because of this, the frequency of the pulses applied to a motor 20 changes with time, and the noise generated by the motor 20 becomes a sound of non- single frequency. Because of this, offensive noise will disappear.

Title: Digital-analog converting circuit
Inventor: NODA TSUTOMU
IPC: H03M1/82
Filed: 1983-08-12
Abstract: PURPOSE:To prevent waveform deformation from being generated to an input signal with a small amplitude by changing the direction of a charging current flowing to an integration device in response to the code of the most significant bit of a digital signal through the complementary constitution of the circuit. CONSTITUTION:Digital data of the most significant bit (MSB) and of bits other than the MSB are inputted respectively to terminals 22 and 23. Further, counters 9, 24 are changed over by current switches 6, 7 and 27, 28 in response to the value of the MSB. Moreover, a changeover circuit 34 adds 1 to the data without any change when the MSB 1 and after inverting the data other than the MSB and sets the data to the counters 9, 24. Then a capacitor 2 is charged from current sources 4, 5 and 25, 26 to obtain an analog value in response to the digital data. When the MSB is logical 1, the conductive period of the constant current source 5 of the low-order bit side is made longer as the data other than the MSB is increased at first and the constant current source 4 of the high-order bit side is also conducted next. On the other hand, when the MSB is 0, the constant current sources 26 and 25 of the low-order and the high- order bit side are operated similarly above as the data other than the MSB is decreased.
