Title: Mechanism for correcting air volume upon acceleration in fuel injection device for internal-combustion engine
Inventor: TOMINARI NOBORU
IPC: F02D41/02
Filed: 1981-06-22
Abstract: PURPOSE:To obtain proper mixture by a method wherein insufficient air volume is corrected when the treading speed of an accelerator is arrived at a predetermined speed in the fuel injection device for a fuel system. CONSTITUTION:The system is constituted so that a valve 5 is controlled by a computer 3, receiving the outputs of pressure sensers 8, 9 at the upstream and the downstream of a throttle valve 5 on an air supply path 7, the output A of a position detecting senser for the accelerator 2 or the like, through a servo mechanism 4. An air supply valve 6, which is the mechanism for correcting the air volume, is arranged at the downstream of the valve 5. When the treading speed of the acccelerator 2 has arrived at the predetermined valve or more, the computer 3 operates the valve 6 to correct the insufficient air volume q due to the time delay to of the command curve c of the output C of the mechanism 4 with respect to the command curve a of a necessary air volume determined by the output A. According to this method, proper mixture may be supplied even upon accelerating suddenly and knocking or the like may be prevented.

Filed: 1993-03-30
Abstract: PURPOSE:To shorten the heating time required for supplying hydrogen by forming a hydrogen supply film for supplying hydrogen to the channel layer before forming the wiring layer of the source or drain electrode. CONSTITUTION:A hydrogen supply layer 21 for supplying hydrogen to a channel layer 3 formed on a substrate 2 is formed before a wiring layer 23 of the source of drain electrode is formed. After an layer insulating film 6 as the first layer covering a gate electrode 5 is formed, a plasma silicon nitride film 21 is formed and a hydrogen group is diffused into the channel layer by a heat treatment.
