Title: Secondary monitoring radar device
Inventor: SHIGIYOU CHIKAAKI
IPC: G01S13/74
Filed: 1999-01-12
Abstract: PROBLEM TO BE SOLVED: To provide a means for eliminating a pseudo target according to the multipath phenomenon. SOLUTION: Since the electronic wave propagation path of the reflection wave of an aircraft response due to multipath is longer than that of a true direct wave, the reception time is delayed. Also, since the reception power level of the reflection wave of the aircraft response due to the multipath is attenuated as compared with the reception power level of the true direct wave, the time stamp of the reception time is made by the target detection part of an aircraft according to time from a reference time generation part 7, and comparison is made with the time stamp time with an aircraft having the same identification information of the response signal from the aircraft as a target by a multipath suppression part 9, thus suppressing the target data with slower reception time.  Also, the reception level of a reception signal is measured, and the reception level of a response signal from the aircraft is compared with an aircraft having the same identification information of the response signal from the aircraft as a target by the multipath suppression part 9, thus suppressing the target data with a low reception level.

Title: Measuring method for characteristic of semiconductor element
Inventor: OKA MUTSUMI
IPC: H01L21/66
Filed: 1993-01-18
Abstract: PURPOSE:To prevent deterioration of characteristics of an element by performing plasma-etching for a nitride film up to a thickness of 500Angstrom  and by measuring characteristics by etching the remainder with hydrofluoric acid solution to expose a surface of a metallic wiring. CONSTITUTION:When a nitride film 9 is etched by plasma, it is not completely etched and removed as in a conventional method but is etched extremely thin, i.e., 500Angstrom  or less. Then, Al electrodes 5, 6, 7 are exposed by etching the remaining nitride film 9 with buffered hydrofluoric acid to enable probing. Since buffered hydrofluoric acid covers a p-n junction surface and an oxide film 8 thereon during exposure, plasma ion by plasma etching does not enter the p-n junction surface unlike usual. Therefore, characteristic deterioration of an element can be prevented.

CONSTITUTION:A recess is provided at one part of an outer lead, and the lead width is narrower than the width of the wiring pattern of a frame 5 for stacking, and the opposed part of the through hole 8 provided at the wiring pattern part of the frame 5 is smaller than the through hole diameter. Since the line width of the outer lead 6 is smaller than the terminal 7 for connection of the frame 5 for stacking the space, in which fused solder can remain in the interlayer junction part, arises, and the quantity of solder flowing between the terminals for connection can be decreased, and solder protrusion to between terminals becomes small, and the short between terminals for connection can be prevented, and the connection strength can be raised. The solder of the lead part 7 flows in the through hole from the space, which is caused by the through hole 8 not being completely closed with an outer lead 7, and the wettability of the through hole part 7 becomes uniform, and the difference of connection strength between terminals becomes small.
