Title: Exhaust gas purifier for engine
Inventor: TANAKA HIDEKI
IPC: F02D21/08
Filed: 1979-08-31
Abstract: PURPOSE: To purify exhaust gas during warming up of an engine by performing exhaust recirculation and reduction in an air fuel ratio on the basis of each of two stages into which the warming up condition of the engine is divided.  
     CONSTITUTION: The signal of an O 2  sensor 8 attached to an exhaust pipe 5 of an engine 1 is input to an air fuel ratio controller 9, which controls a corrective unit 7 to vary an air bleed amount of a carburetor 3 or other factors. Suction and exhaust systems 4, 5 are communicated by an exhaust gas recirculation passage 10 which includes a control valve 12. A three-way solenoid valve 15 receiving a signal of a warming-up condition detector 17 is provided in a passage 13 which leads a suction pipe negative pressure into a negative pressure chamber inside the control valve 12. Under the state from the cooling condition to the first warming-up, the solenoid valve 15 is opened to perform gas recirculation only. When the condition is shifted from the first to the second warming-up, supply of air bleed is performed along with the recirculation by initiating the control of the corrective unit 7 so that an air fuel ratio may be reduced.

Title: Push-pull thyristor amplifier
Inventor: INABA HIROMI
IPC: H02M7/17
Filed: 1978-09-14
Abstract: PURPOSE:To realize a high stability in case the polarity of the load current is changed suddenly by setting the minimum ingnition angle to 10 degrees or more for the ingnition pulse in the single-phase and full-wave push-pull thyristor amplifier which uses the intermediate tap transformer as its power source. CONSTITUTION:In case thyristor th3 has ignition when thyristor th1 has ignition, a large amount of circulation current flows. However, the reverse voltage is applied to th3 to block the ignition by commutating the load current to th2 from th1 before ignition of th3. The ignition signals of th1 and th2 are not stopped even in case the load current is lowered from the positive to negative level. On the contrary, load L features the inductive load by leaving the ignition angle at the fixed level or more. As a result, the increment of the circulation current can be avoided when the polarity of the load current is switched suddenly.
