IPC: F02D23/02
Filed: 1990-04-05
Abstract: PURPOSE:To restrain the gasification of injected fuel in medium load running and reduce combustion noises in an engine wherein the fuel injected into a combustion chamber is ignited by an ignition plug, by controllably setting the fuel injection timing in the medium load running later than that in low and high load running. CONSTITUTION:In a 2-cycle internal combustion engine in which an ignition plug is disposed in the center of the inner wall surface of a cylinder head 3 and a fuel injection valve 21 is disposed in the periphery of the intake valve 6 side inner wall surface of the cylinder head, when fuel injection from the fuel injection valve 21 is controlled by an electronic control unit 30, an exhaust valve 7 is opened earlier than the intake valve 6 and the injected fuel is ignited by the ignition plug 10 at the end of compression stroke. Then, the injection start timing is controllably delayed in the maximum degree during the medium load running of an engine wherein fuel grains have the highest temperature to promote the gasification of fuel so that the fuel becomes liable to be burnt in the early timing.

Title: Soi transistor and manufacture thereof
Inventor: YU ZENNICHI
IPC: H01L21/762
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device having an SOI transistor and also to provide a method for manufacturing the device. SOLUTION: In the transistor, a channel region 54 and a source region 52 are partially contacted simultaneously with a part region of an insulating film 46 and a part region of a conduction film 49 having a doping concentration higher than that if the channel region 54. Thereby the movement of holes to the source region 52 can be facilitated so that the accumulation of excessive holes in the channel region 54 can be avoided, variations in the threshold voltage of the transistor can be prevented, and a floating body effect(FBE) can be also suppressed. Further, since the conduction film 49 is doped with impurities at a high concentration, these impurities act as a stopper for blocking punch through between the source 52 and drain 50, thus improving an SCE in the transistor.
