Title: Air-fuel ratio control device for internal combustion engine
Inventor: HOSHI KOICHI
IPC: F02D41/00
Filed: 1988-02-08
Abstract: PURPOSE:To restrict overcorrection of the amount of feedback control by shortening a specified delay time up to a start of air-fuel ratio feedback control at the time of switching the air-fuel ratio from a specified air fuel ratio to a theoretical air-fuel ratio in accordance with the increase in catalyst- degradation rate of a three component catalyst. CONSTITUTION:When it is decided by a decision means M7 that the operating condition of an internal combustion engine M1 detected by a detection means M6 is in a switching time in which the operating condition is controlled from a specified air fuel ratio to a theoretical air-fuel ratio, an air-fuel ratio control means M10 starts feedback control through an air fuel ratio regulating means M5 based on the output of an air fuel ratio detecting means M4 after the elapse of a specified delay time through a delay means M8. In this instance, a changing means M12 shortens the specified delay time in accordance with the increase in degradation rate of a three component catalyst M2 calculated by a catalyst- degradation rate calculating means M11. Thus, when the oxygen storage effect is reduced due to degradation of the catalyst, the delay time is shortened, and overcorrection of the amount of air fuel ratio feedback control can be prevented.

IPC: G01S7/282
Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To obtain a phased-array radar apparatus in which the width of a gate signal is adjusted and which enhances the ratio of a transmission-signal level to a sideband level by changing the counting initial value of the rise counter and that of the fall counter of an FF used to generate the gate signal. SOLUTION: A transmission reference trigger is differentiated by a wave-front differentiator 11 so as to be input to a rise counter 12. The rise counter 12 delays a wave-front differential waveform by the time of the integral multiple of a clock cycle on the basis of a preset counting initial value so as to be output. At the same time, the transmission reference trigger is differentiated by a wave-front differentiator 13 so as to be input to a fall counter 14. The fall counter 14 delays a wave-tail differential waveform of the clock cycle on the basis of the preset counting initial value so as to be output. Outputs of the counters 12, 14 are input to an FF 15, and a gate signal is generated. In this manner, initial values of counters 12, 14 are changed, the width of the gate signal is changed, and the ratio of a transmission signal level to a sideband level can be improved.

Title: Constant current circuit
Inventor: TEZUKA HIDEHARU
IPC: H03F1/30
Filed: 1982-02-23
Abstract: PURPOSE:To decrease greatly the number of elements to be used to obtain a constant current circuit which excels in the characteristics of temperature, load and voltage, respectively, by substituting a transistor for an operational amplifier. CONSTITUTION:The emitter voltage phi3 of a transistor TRQ5 is obtained from the reference voltage phi1+{VBE(Q12)-VBE(Q5)} which is obtained at an end of a constant voltage element 1, where VBE(Q12) and VBE(Q5) show base-emitter junction voltages of TRQ12 and Q5, respectively. The temperature characteristics are equal to each other between these voltages in terms of an IC. At the same time, the VBE(Q12) is equal to the VBE(Q5) since the emitter currents of the TRQ12 and Q5 are equal to each other as I1=I0 owing to a current mirror. As a result, phi3=phi1 is satisfied. Then the voltage applied to a resistance R2 is always set at a constant level. This ensures the stability to temperatures owing to the element 1.
