Abstract: PURPOSE: To improve purification performance for CO and NOx at a wide air-to- fuel ratio range by making Pt and Rh, which are active components, carried on a carrier at specific concentrations in a monolith type 3-element type catalyst for purification of waste gas of automobiles.  
     CONSTITUTION: A monolith type 3-element catalyst A is disposed in a catalyst device 2 provided in the exhaust pipe 1 of the engine of an automobile. This catalyst A is prepd. by impregnating Pt and Rh on a catalyst carrier 3 of cordierite composition, and changing the amount of impregnation of Pt so as to be made rich on the waste gas inlet 3a side of the catalyst carrier 3 and lean on the waste gas outlet side 3b. Also, that of Rh is so changed and carried as to be made conversely lean or nil on the waste gas inlet side 3a and be rich on the waste gas outlet side 3b. As a 3-element catalyst for HC, CO and NOx, this catalyst excells particularly in purification performance for CO and NOx and permits the expansion of the air-to-fuel ratio to be used.

Title: Drive control circuit of brush motor
Inventor: SHINOHARA SADAO
IPC: H03K17/66
Filed: 1985-02-18
Abstract: PURPOSE:To eliminate the flow of a penetrating current by outputting a normal rotation signal, a reverse rotation signal and a brake signal through a signal delay circuit. CONSTITUTION:When a signal IN1 is set to H, the output of a gate circuit 33 becomes H, and the output of a signal delay circuit 34 becomes H after the prescribed time. Thus, transistors 43, 46 become ON, and a motor 40 rotates in a normal direction. When the signal IN1 is then set to L and IN2 is set to H, the output of the gate circuit 33 becomes L, and the output of a gate circuit 31 becomes H. At this time, the output of the circuit 34 becomes L, and the transistors 43, 46 become OFF. The output of a signal delay circuit 32 becomes H after the prescribed time, transistors 44, 45 become OH, and the motor 40 rotates reversely. Thus, a penetrating current is eliminated when an operation mode is varied.
