Abstract: PROBLEM TO BE SOLVED: To make it possible to judge a reinforcement effect by transforming the time region data on normal tremors before and after a countermeasure action into spectrums, obtaining the spectral ratio, graphing the relation with frequency, and confirming a ridge and a valley across a specific value. SOLUTION: A pickup PU is installed on a structure, and normal tremors before and after a countermeasure action are measured and stored in a hard disk 21. A transformation section 22 Fourier-transforms the time region data on the stored normal tremors to obtain two Fourier spectral data, and a comparison section 23 compares both data to obtain the Fourier spectral ratio. A monitor 30 displays the relation between the spectral ratio and frequency in a graph. When the graph shows a ridge and a valley across 1.0, it is judged that a reinforcement effect is obtained. When they are not clearly shown, it is judged that no reinforcement effect is obtained. The reinforcement effect can be judged only by the measurement of normal tremors and no large-scale facility is required.

Title: Semiconductor integrated circuit device
Inventor: TANIGUCHI MASAHARU
IPC: H01L27/08
Filed: 1982-05-06
Abstract: PURPOSE:To improve latch-up resistance without lowering dielectric resistance between a substrate and an island by forming the buried layer of a diffusion region of the same conduction type as the substrate and high concentration so as not to be brought in contact with the island in the C-MOSIC. CONSTITUTION:The buried layer 112 of the n<+> type region is formed just under sections except the island 106 so as not to be in contact with the P<-> type island 106. When positive surge voltage is applied to an output terminal OUT in the IC constituted in this manner, the base concentration of PNP transistors TRs 1, 2 formed between each layer becomes higher by the layer 112 when the layer 112 is formed so as not to be in contact with the island 106, thus increasing numbers of which carriers recombine in a base. Accordingly, flowing currents reduce only by the increase, an amplification factor drops, and latch-up resistance increases. Dielectric resistance between the island 106 and the substrate 105 does not lower because n<+> of high concentration does not collide with the island 106 even when it floats. The amplification factor does not increase because the base length of NPNTRs 3, 4 also does not change.

Title: Fine adjustment mechanism for feeding wire in spring manufacturing machine
Inventor: TAKANO SENSHIROU
IPC: B21F3/06
Filed: 1989-03-29
Abstract: PURPOSE:To easily and quickly make fine adjustment without stopping operation by rocking a sector gear through a rotary member and an adjusting lever, setting the radius of gyration of the rotary member and rocking the adjusting lever by this rotation through the engagement of its pin with a groove. CONSTITUTION:Wire feed rollers 1, 2 are rotated intermittently to feed a wire by prescribed length. A sector gear 7 is fluctuated through a rotary member 5 and an adjusting lever 6. In other words, as the radius R of gyration of the rotary member 5 is set, an adjusting lever 6 is rocked by the rotation of the rotary member through the engagement of the pin 21 with the groove and, therewith, the sector gear 7 is rocked. The rocking angle of the adjusting lever is adjusted by changing the position of the fulcrum 26 and thereby the fine adjustment of the sector gear is made. Besides, the amount of feed (main feed) of the wire is changed by changing the radius R of gyration of the rotary member. Thus, high-precision adjustment can be made and since it accompanies no impact a desirable effect is obtained from the view point of operation.
