Abstract: PURPOSE: To enable the close property discrimination of fuel by computing the fuel injection quantity on the basis of a specified coefficient selected by a coefficient selecting means, and judging whether an air-fuel ratio is in a normal range in the actually injected state of the fuel. CONSTITUTION: At the time of starting an engine 1, the detection signals of a crank angle sensor, an airflow meter 4, an oxygen sensor 8, a fuel property sensor 15, and the like are read into a control unit 17.

In association with the operation of an engine, whether an air-fuel ratio is within a property range close to a stoichiometric air-fuel ratio is judged from the output of the oxygen sensor 8.  In the negative case, it can be so judged that a coefficient for computing the basic injection quantity does not coincide with the property of the fuel F, so that another characteristic line is read, and the density of the fuel F is property-discriminated on the basis of the delay time of ultrasonic wave detected by the fuel property sensor 15.

Title: Method for detecting lsi short-circuiting failure
Inventor: HAMADA HIROYUKI
IPC: H01L21/66
Filed: 1996-12-16
Abstract: PROBLEM TO BE SOLVED: To detect a wiring short-circuiting location in an LSI by emitting charged particle beams to the surface of an LSI without externally connecting a power supply and other electrical signal to the LSI and observing secondary electrons emitted from it. SOLUTION: When the left edge of a second wiring is irradiated, the initial potential of the wiring is reflected, so that the difference from the observed amount of secondary electron when the right edge of a first wiring is irradiated is increased. However, when the left edge of a third wiring is irradiated, the second and third wirings are short-circuited, so that a potential when the right side of the second wiring is irradiated is reflected, and the observed amount of the secondary electron becomes nearly identical to that in the case when the right edge of the second wiring is irradiated.  By utilizing this property and scanning electron beams from left to right, the observed amount of the secondary electron in the case when the right edge of the wiring is irradiated is compared with that in the case when the left edge of the right wiring is irradiated, thus it is judging that the wiring is short-circuited when the absolute value of the difference is at most a certain value.
