Title: Lead material for electronic component, lead using the same and semiconductor device
Inventor: TANIMOTO MORIMASA
IPC: H01L23/50
Filed: 1997-11-11
Abstract: PROBLEM TO BE SOLVED: To enhance the solderability of a lead material and to make it possible to increase the welding strength of the welding part of the lead material with an aluminium wire or the like, by a method wherein the melting temperature of a second plated layer is made lower than that of a first plated layer. SOLUTION: A plated layer of two-layer structure, wherein a first plated layer 2 and a second plated layer 3 are laminated in this order of the layer 2 and the layer 3 on the surface of a conductive substrate 1, is formed. In this lead material A, the melting temperature of the layer 3, which is the uppermost layer, is set lower than that of the layer 2, which is positioned under the layer 3. Therefore, even if the layer 3, which is the uppermost layer, is molten when soldering to the uppermost layer is performed, melting of the layer 2, which is positioned under the layer 3, is not caused. As a result, this layer 2 results in functioning as a barrier to Cu or the like diffusing thermally from the conductive base body 1 by heat at the time when the layer 2 is soldered.  Accordingly, the deterioration of the solderability of the material A is inhibited and a good bonding strength between a solder on the layer 2 and a solder on the layer 3 is obtained.

IPC: G01R17/20
Filed: 1987-12-07
Abstract: PURPOSE:To prevent restriction on a driving range with the length of a closed magnetic circuit, by providing permanent magnets at the outside of a moving path for a magnetic detector. CONSTITUTION:A potentiometer is composed of the following parts: a closed magnetic circuit 16 comprising counter parallel thin plates 11 and 12 made of magnetic material and permanent magnets 13 and 14, which are held between said facing plates; and a magnetic detector 15, which linearly moves between the counter plates and detects leaking magnetic flux between the counter plates. The permanent magnets 13 and 14 are provided at the outsides of the extending lines of a moving path for the magnetic detector 15. Namely, the closed magnetic circuit 16 comprises a pair of the facing U-shaped thin plates 11 and 12 and the permanent magnets 13 and 14, which are held with end parts 11b, 11c, 12b and 12c, which are made to extend from the side surfaces of the thin plates 11 and 12. The gap between the central parts 11a and 12a of the thin plates 11 and 12 is the moving path of the magnetic detector 15. Therefore, the moving range of the magnetic detector 15 is not restricted. The magnetic detector 15 can be attached to a material to be measured, which moves in a range broader than the measuring range.

Title: Medical diagnosis support system
Inventor: TAGUCHI KATSUYUKI
IPC: G16H10/60
Filed: 1994-12-13
Abstract: PURPOSE: To read the pictures of plural sheets and plural examinees by using CAD by determining a tomographic picture doubtful of being a morbid part as a remarked picture from among plural sheets of the tomographic pictures. CONSTITUTION: A CPU 23a compares the judged result data of a CAD device 4 in all the re-constituted pictures (all slice pictures) of all patients stored in a memory with the read result data of a doctor. Then, the slice picture from which an abnormal shadow is extracted by the analysis of the CAD device 4 is reconstituted so that it becomes of a pitch smaller than other slice pictures. Namely, since the picture the CAD device 4 judges to be normal is usually normal in practice, the slice pitch of this part is made coarse. On the other hand, when an area the CAD device 4 judges to be abnormal is made into the fine slice pitch, the area the CAD device 4 judges to be abnormal comes to be read minutely even though all the pictures are read within the same period of time.
