Title: Fuel feed device and fuel feed control method
Inventor: FUJISHITA MASAKATSU
IPC: F02M37/20
Filed: 1994-04-28
Abstract: PURPOSE:To eliminate a fuel return pipe line and control a fuel injection amount over a wide range by introducing a fuel pressure control system for keeping the fuel pressure of a fuel injector constant, in addition to the on/off control of the fuel injector. CONSTITUTION:A control device 10, upon receipt of a signal for fuel pressure in a reservoir tank 6 from a fuel sensor 8, controls the delivery flowrate of a fuel pump 2 to draw and pressurize fuel 3 in a fuel tank 1 and jet fuel from a fuel injector 7, depending on the speed of the pump 2 that is voltage applied thereto. According to this construction, fuel pressure in the reservoir tank 6 is accurately controlled at constant level, and no excess fuel is supplied, thereby eliminating a return pipe line. Also, several types of fuel injection characteristics can be obtained with the same fuel injector, when an established fuel pressure value is changed, and the fuel injector can be standardized. In addition, the saturated fuel vapor pressure can be temporarily increased to restrain the occurrence of a vaporization phenomenon.

Then, a wiring material of Al, polysilicon or the like is deposited on the surface of the interlayer insulating film 6 and then patterned into first wiring patterns 7a and 7b and a dummy pattern 8 through a lithography process. At this point, the first dummy pattern 8 or a second wiring pattern 10 is so formed as not to two-dimensionally overlap each other, whereby an inter-board capacitance is prevented from increasing markedly due to the formation of the dummy pattern 8. By this setup, each wiring pattern of a multilayer interconnection structure can be flattened through a CMP method without deteriorating a semiconductor device in high speed operation properties.

Abstract: PURPOSE:To obtain one's own position continuously by a method wherein, when a combination of GPG (global positioning system) satellites is changed, the difference of one's own position which has been found by combinations of satellites before and after the change is found and corrected. CONSTITUTION:Whether a combination of satellites selected by means of a satellite selection part 7 has been changed over or not is judged by means of a positioning computation part 4. When it is judged that the combination has been changed over, a correction computation part 5 finds one's own position by means of the combination of satellites before its changeover and one's own position by means of the combination of satellites after the changeover, and the difference of one's own position is computated. The positioning computation part 4 executes a sequential positioning computation on the basis of a pseudo-distance which has been found by means of a pseudo-distance measuring part 3; it finds one's own current position. A correction part 6 adds the difference to one's own position which has been found, and corrects one's own position. Thereby, even when the selection of satellites is changed over by means of the satellite selection part 7, one's own position is not changed discontinuously, and it is possible to obtain one's own position continuously even when a fishing vessel is operated.
