Title: Series compensating device and switching element controlling device
Inventor: KONISHI HIROO
IPC: H02J3/16
Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To enable a switching element to operate properly at the time of a system failure and the elimination of the failure. SOLUTION: The phase difference between a synchronizing pulse signal Sn that is synchronized with the current of a system and a reference pulse signal Ss is detected by a phase difference detecting circuit 44. This phase difference Δθ is amplified by a calculating and amplifying circuit 46 to obtain a control voltage Ec and to generate a pulse signal of an oscillating frequency in proportion to the control voltage Ec by a voltage controlling and oscillating circuit 56. The frequency of this pulse signal is divided by a frequency divider circuit 58 to generate a reference pulse signal Ss. Based on this signal, a firing pulse signal for igniting each thyristor is generated.  If a failure occurred in the system, a pulse signal is generated of the oscillating frequency based on the control voltage Ec' that has been stored in a phase memory circuit 54 prior to the occurrence of the failure. Then, the frequency of this pulse signal is divided by the frequency divider circuit 58 to generate the reference pulse signal Ss.

Title: Method for controlling air-fuel ratio of engine with exhaust gas recirculating device
Inventor: ITO YUZURU
IPC: F02D21/08
Filed: 1988-06-22
Abstract: PURPOSE:To prevent a temporary over-rich/over-lean condition by correcting an injecting fuel quantity during the operation delay time of an EGR valve according to a correcting quantity based on engine speed and the changed value of an intake-pipe negative pressure. CONSTITUTION:A fuel injection quantity in a steady condition is calculated based on an intake-pipe pressure from an intake pressure sensor 11 and engine speed by an arithmetic and control unit 13. A fuel injection correcting quantity corresponding to the delay in operation of the valve 10 of an EGR 7 is calculated from the changed values of the intake-pipe pressure and engine speed. The fuel quantity injected during the operation delay period of the valve 10 is corrected by this correcting quantity. Hence, because of the changes in the intake-pipe pressure and engine speed due to the rapid accelerating/decelerating operation of an engine 4, even if the delay in operation of the valve 10 takes place or even if the delay is not constant, it will not take place that an air-fuel ratio becomes temporarily over-rich or oven-lean.

IPC: H04N21/43
Filed: 1983-08-24
Abstract: PURPOSE:To correct automatically the relative time difference among plural information signals which are transmitted through the same system at the same time by inserting synchronizing signals into plural information signals. CONSTITUTION:Synchronizing signals (marker signal) are inserted into a sound signal and a video signal previously at a transmission side, and the sound signal is transmitted while advances in phase ahead of the video signal by a specific time T. The sound signal received at a reception side is supplied to a terminal 1 and its marker signal is detected by a marker detecting circuit 3. The video signal supplied to a terminal 2 is supplied to a marker detecting circuit 4 to detects its marker, and they are supplied to a time difference measuring circuit 5. This time difference measuring circuit 5 measures the time difference between both marker signals and stores it in a trailing-stage measured value storage circuit 6. When the measurement is taken at least twice, the start signal from the time difference measuring circuit 5 allows a decision circuit to decide on whether the delay time of the sound signal to the video signal should be corrected or not on the basis of the current measured value T1 and past measured value T2 stored in the measured value storage circuits 6 and 7.

Title: Test method for counter
Inventor: NISHIO HARUHIKO
IPC: H03K21/40
Filed: 1981-09-28
Abstract: PURPOSE:To quickly test each counter with a test use acceleration clock signal, by shifting the phase of a carry signal or a clock signal and supplying in parallel to a plurality of counter in series connection while preventing overlapping of  both signals. CONSTITUTION:A test use acceleration clock signal 5a is applied to counters 5, 11... from a terminal A. Further, an inverted acceleration clock signal 6a is applied to an even number counter 6,.... Each counter catches the trailing of pulses for count operation. In case of a decimal counter, when each counter counts the 10-th pulse, a carry signal 5b or 6b is outputted to the counter of the next stage. That is, the carry signal 5b of the 1st counter 5 is outputted to the 2nd counter 6. Since the inverting clock signal 6a is applied to the 2nd counter 6, the carry signal 5b is counted as the next pulse of the count value without being overlapped with the inverted clock signal 6a.
