Title: Air fuel ratio controller of internal combustion engine
Inventor: AOTA HIROYUKI
IPC: F02D41/14
Filed: 1993-09-03
Abstract: PURPOSE:To steadily feed a purge flow without using a low duty ratio range of a flow control valve, where the operation of an internal combustion engine becomes unstable. CONSTITUTION:The amount of fuel to be fed to an internal combustion engine 1 is adjusted by an injector 6 based on the output signal from an electronic control unit(ECU), 16. The opening of a purge duty vacuum switching valve(VSV) 14 is adjusted by means of duty ratio control based on the pulse width modulation of the ECU 16, and the purge flow of air to be fed to the internal combustion engine 1 containing evaporated fuel from a canister 11, by which the evaporated fuel in a fuel tank 10 is absorbed, is adjusted. Since the purge duty VSV 14 is driven only when the duty ratio is no less than a predetermined value, variation in the purge flow is limited to a low level, resulting in no large fluctuation in air fuel ratio, and degradation of exhaust emission is thus prevented.

Title: Semiconductor device and its manufacture
Inventor: AOKI HIDEO
IPC: H01L23/522
Filed: 1998-08-04
Abstract: PROBLEM TO BE SOLVED: To prevent resistance increases of wiring layers due to dishing which occurs in the course of CMP by preventing disconnection or resistance increases caused by insufficiently buried wiring layers in groove sections. SOLUTION: In a semiconductor device in which wiring layers 6 are laminated through interlayer insulating film 20 are connected to each other through plugs 21 formed penetrating through the insulating film 20, grooves in which the wiring layers 6 are formed are formed into the insulating film 20, after the plugs 21 are formed to the upper surface of the insulating film 20 and the wiring layers 6 are formed in the grooves. Consequently, the plugs 21 reach the upper surface of the wiring layers 6, and the side faces of the plugs 21 are connected to the wiring layers 6. Therefore, disconnection and resistance increases in the wiring layers 6 due to their insufficiently buried states can be prevented through forming wiring layers by partially extending the plugs instead of the wiring layers 6 in such portions that the wiring widths are narrow.  In addition, dishing can be prevented, because the plugs 21 reaching the upper surfaces of the wiring layers 6 prevent the excessive polishing of copper films during the course of CMP.
