Title: Integrated circuit tester and integrated circuit testing method
Inventor: SASAKI MAKOTO
IPC: G01R31/319
Filed: 2000-02-03
Abstract: PROBLEM TO BE SOLVED: To correctly judge, at a low cost, whether an integrated circuit operating at a high speed is defective or not. SOLUTION: When test pattern data 124 is supplied from a pattern memory 110 to an LSI 104 in synchronization with a reference clock signal 120, the LSI 104 operates based on the supplied data 124 to output data 104A corresponding to the data 124 and a strobe signal 8. In synchronization with the signal 8, a result memory 6 takes in and holds the data outputted by the LSI 104. After all the data outputted by the LSI 104 correspondently to the data 124 is taken in and held by the memory 6, a test control means 106 controls the memory 6 and an expected-value memory 4 so that the memories 4, 6 successively output their held data to a comparison circuit 112. The circuit 112 compares the two groups of data with each other to judge whether or not the two coincide with each other.

Title: Fuel injection nozzle
Inventor: KATO MASAAKI
IPC: F02M61/10
Filed: 2000-02-04
Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection nozzle capable of preventing fuel leakage with a simple structure, feeding spray according to an operating condition of an engine, reducing NOx, black smoke, and HC, and improving power. SOLUTION: Fuel pressure in a fuel passage hole 23 outwardly expands an inner wall of the fuel passage hole 23 in valve closing to elastically deform and radially expand a second middle diameter part 28 and make a gap 33 smaller. Leakage of high-pressure fuel to a low-pressure part is prevented by changing the gap 33 between a valve needle 2 and a nozzle body 3 according to the fuel pressure. Leakage of fuel from a group of nozzle holes 40 can be thereby prevented to reduce hazardous component in exhaust gas, and lubrication and cooling of the valve needle 2 can be made excellent to prevent generation of deposit and seizure in the fuel injection nozzle 1. Since a passage for recovering leakage fuel is not required to be formed, manufacturing cost can be reduced by simplifying the structure of the fuel injection nozzle 1 capable of making opening area of the group of nozzle holes 40 variable.
