Title: Air-fuel ratio control device for engine
Inventor: TANAKA HIDEKI
IPC: F02D41/04
Filed: 1986-01-17
Abstract: PURPOSE:To reduce an output fluctuation due to a change in air-fuel ratio by changing an air-fuel ratio control means over to the lean side in step rather than to a theoretical air-fuel ratio, and opening and closing a valve device within a bypass passage bypassing a throttle valve with a control means. CONSTITUTION:When an engine 1 is running, ECU 22 is inputted with a water temperature signal 'Tw' from a water temperature sensor and an opening signal 'TVtheta' from a throttle sensor 21. If water temperature 'Tw' is lower than predetermined temperature 'T1', or 'Tw' is higher than 'T1' and the throttle opening 'TVtheta' exceeds predetermined opening 'theta1', air-fuel ratio control is made to go on according to a theoretical air-fuel ratio. Namely, when the engine 1 is in an idling state in this case, a valve device 18 within a bypass passage 17 formed bypassing a throttle valve 5 is made to open, while said device 18 is made to close in non-idling operation. Also, when 'Tw' is higher than 'T1' and 'TVtheta' is less than 'theta1', the valve device 18 is made to open and a large quantity of intake air is fed to a combustion chamber 9, thereby enabling the engine 1 to be operated on a lean air-fuel ratio.

Title: Angle steel processing apparatus
Inventor: HERUMUUTO ROSHIBUARU
IPC: B23Q37/00
Filed: 1984-01-23
Abstract: An apparatus for working a elongated angle-iron workpiece having a pair of nonparallel flanges at least one of which is to be drilled has a transport unit for displacing the workpiece longitudinally through a working station and a support in the station for holding the workpiece with the one flange forming an acute angle with the horizontal. A drilling unit including a drilling tool can move horizontally in the station transverse to the workpiece and transverse to the workpiece and at the acute angle to the horizontal perpendicularly through the one flange. To obtain a given displacement along the workpiece flange, the carriage supporting the drill unit is moved horizontally through a horizontal distance equal to the desired displacement times the secant of the angle that the flange forms with the horizontal. The drilling tool can be moved perpendicularly of the one flange during displacement of the carriage through the horizontal distance through a distance equal to the predetermined distance multiplied by the tangent of the acute angle the one flange forms with the horizontal so the drilling tool does not change spacing from the one flange during horizontal adjustment.
