Inventor: YAMAGUCHI NOBORU
IPC: H01L21/66
Filed: 1986-08-20
Abstract: PURPOSE:To diagnose trouble quickly and precisely by detecting the input/output signal row of a functional block for a logic IC during operation in a noncontact manner, conducting logic simulation by an input signal row obtained and analyzing mismatch information with a noncontact output signal row. CONSTITUTION:A functional block 2 for an IC chip 1 during operation is irradiated with electron beams, and signal potential is observed 3, and converted 4 into logic information. Conversion timing is displayed by phase difference with a fundamental clock, and indicated by a general purpose computer. Relative movement is acquired from the absolute coordinates where mask information existing in the computer 7 is obtained, and the shifting of a sample base and a beam deflection angle are controlled, thus determining 5 an observation point. A general purpose tester 6 outputs test information memorized to the IC 1 according to timing control information. The computer 7 stores test information, the mask pattern information of the chip 1 and logic connection information, and has a program, from which the positional coordinates of a signal line are acquired, and a logic simulator. According to the constitution, troubles can be diagnosed rapidly by predetermined operation.

Title: Stud thread structure
Inventor: HASHIGUCHI SATORU
IPC: F16B31/06
Filed: 1997-07-17
Abstract: PROBLEM TO BE SOLVED: To enhance fatigue strength by making the root of a stud thread larger than that of a standard thread, and enlarging an inner diameter on the internal thread side. SOLUTION: The root R (R=R1) of a stud thread in relation to a thread pitch P is to be R1=0.108P-0.144P, and the minimum value Dmin of a corresponding internal thread inner diameter is to be Dmin=d2 max-2(H/2-3/2.Rmax), Dmin=d2 max-H+3Rmax, where d2 max is the maximum value of the effective diameter of the stud thread, H is 0.866025P, Rmax is the maximum value (0.144P) of the thread root R, from the geometric relation so as not to interfere with the root of an external thread. With this constitution, in case of fastening the stud thread to the internal thread to fit a mechanical element, stress concentration on the stud thread is relaxed, so that stress applied to the stud thread is reduced. Fatigue strength as stud thread structure is therefore enhanced.
