Title: Signal detection system
Inventor: YAMASHITA JIYUNJI
IPC: G01S7/32
Filed: 1984-07-09
Abstract: PURPOSE:To detect a low-speed target with good performance by counting unnecessary radar echos (clutter signal) from the target on the basis of two low threshold values, and calculating statistically a detection signal from clutter signals. CONSTITUTION:A signal is inputted from a detection area gate 6 by a radar and inputted to clutter detectors 7 and 8. Detection threshold values of those detectors 7 and 8 are set lower than a target threshold value and made different, and clutter signals larger than the detection threshold value are counted. Then, a clutter counting circuit 9 calculates detection probability values F1 and F2 and inputs them to a clutter parameter circuit 10 to calculate a shape parameter and dispersed values, thereby grasping statistically the clutter signals. Then, a detection reference is so calculated by a detection reference arithmetic circuit 13 so that the probability of wrong detection is 10<-k>. This detection reference is inputted to a memory 12 and outputted from a target detector 11. Thus, the clutter signals are calculated statistically to obtain the detection reference signal, so the search target is detected with good performance.

Title: Machine for driving fixing pin into laminated printed substrate
Inventor: YOSHIDA ISAO
IPC: H05K3/46
Filed: 1987-06-07
Abstract: PURPOSE:To perform work rapidly with high accuracy by performing the formation of pin holes, driving and cutting of pins during the conveyance of the pins, thereby conveying them while fitting reference pins of a laminated printed substrate to a guide groove which is parallel to conveyers. CONSTITUTION:Once a laminated printed substrate 1 is conveyed through conveyers 11, its substrate 1 advances while being guided by a guide groove 12 through a reference pin 5. If a stopping mechanism operates, it causes the substrate 1 to stop at a part of a boring device 20. When a drive controlling device 60 operates in such a state, the device allows the boring device 20 to drive so as to make pin holes at the prescribed places of the substrate 1. Then, a device 30 for driving pins is driven to drive fixing pins 34 into the pin holes. Then a cutting device 40 is driven and the fixing pins 34 which protrude downward from the substrate 1 are cut. In this way, the work is performed rapidly and accurately.
