Title: Detecting device for magnetic variation
Inventor: OSAWA MASANORI
IPC: G01D5/244
Filed: 1991-05-31
Abstract: PURPOSE:To obtain a detecting device of magnetic variation which can execute highly-precise detection even when there are various factors of changes such as a change of a gap between a body to be detected and a sensor, nonuniformity in an output of the sensor itself and the temperature characteristic thereof. CONSTITUTION:The present value Dn of a digital output is taken in (S1), the update maximum value Dmax and minimum value Dmin are determined and a hysteresis width H is computed therefrom (S2). When a digital output Di shows a tendency to increase (S3), a binary-coded output Vout is switched over to '1' only when Dn > (Dmin+H) is satisfied (S4, S5). When the judgement at S3 shows a tendency to decrease, on the other hand, the binary-coded output Vout is switched over to '0' only when Dn < (Dmax-H) is satisfied (S6, S7). Since the hysteresis width is updated by using the update maximum/ minimum value, the same angular phase can always be made the time of inversion of the binary-coded output Vout.

Title: Lead frame for semiconductor substrate
Inventor: YAMAGUCHI HIROYUKI
IPC: H01L23/495
Filed: 1982-07-26
Abstract: PURPOSE:To form a lead frame for a semiconductor device whose pattern is difficult to deform and which has good workability by providing bending parts at edges of both outer frame parts. CONSTITUTION:The bending parts 7a and 7b for protecting a bent element mounting part 3 are provided. The lead frame can prevent the external force applied directly onto the element mounting part 3. Thereby, it is not necessary to use a protection plate 9 at the time of packaging. Since the patterns of lead frames do not tightly contact each other even on superposing them each other at the time of packaging, deformations such as the inclination of the element mounting part 3 by rubbing each other during transportation, the inclination of inner leads 4 toward right and left, the generation of stepwise differences by the inner leads 4 in the direction of the plate thickness are eliminated. Further, the generation of deflection due to the residual internal stress of the material of the lead frame is restrained by the increase of rigidity, and accordingly the large improvement of yield at the time of lead frame manufacture can be improved.

Filed: 1985-06-17
Abstract: PURPOSE:To inspect an object sample accurately and automatically by providing a procedure for obtaining density information on the object sample, a procedure for reducing a detection window to a narrow range, and a procedure for judging whether the sample is normal or not as to necessary irreducible conductor intervals. CONSTITUTION:Image information on the sample which is inputted from a television camera is A/D-converted and stored in an image memory in a procedure 1. An initial window is set and adjusted roughly to set a narrowed detection window in a procedure 2. Then, the point where the number of picture elements in pattern area is closets to a pattern designed value at the bottom of the density distribution in the detection window is determined as a slice level as the 1st stage and the density information in the detection window is converted into a binarization value on the basis of the determined level in a procedure 3. Then, the length of the part where the number of picture elements of '1' is continuously zero is compared with the necessary irreducible conductor intervals in the 2nd-the 4th stages to judge whether the sample is normal or not by scanning a peripheral distribution in crossing and diagonal directions. Thus, the accurate inspection is automated by the simple procedures.
