Title: Signal processor
Inventor: HARUHARA HIROSHI
IPC: G01R23/16
Filed: 1981-07-28
Abstract: PURPOSE:To extract only desired signals out of input signals and to increase the ratio between a carrying level and noise, by detecting the signal of a prescribed level out of an output signals of an A/D converter and deleting the output signal of the A/D converter when a detected level is higher than a prescribed value. CONSTITUTION:An input analog signal receives A/D conversion 32, and this digital signal is supplied to a time compression processor 33 to undergo time compression and time division processes. The output signal of the processor 33 is branched into two parts. One of these two branched signals is fed to a zero detector 34 and the other signal is fed to a delaying device 38, respectively. A counter 35 detects the zero level out of the input signals and supplies it to a counter 35. The counter 35 counts the number of zero signals, and this counting value is compared with the reference value through a comparator 36. The comparator 36 inactivates a block time controlling circuit 37 when the reference value is larger than the counting value and actuates the controller 37 when the reference value is smaller than the counting value by delivering a signal to the controller 37. The input signal is delayed by the device 38 by the working time from the detector 34 to the controller 37 and fed to a gate circuit 39. The circuit 39 opens only when the reference value is larger than the counting value, and the input signal is delivered after a D/A conversion 40.

Filed: 1981-07-30
Abstract: PURPOSE:To obtain stable detaining force by sandwiching tensile fibers between an inside metallic sleeve and an outside metallic sleeve inserted onto a plastic pipe and press sticking the outside metallic sleeve. CONSTITUTION:After a plastic sheath 3 of a reinforcing tube for optical fibers is stripped in a prescribed position, tensile fibers 2 are placed uniformly on the circumference of a plastic pipe 1 by inserting a metallic inside tube 10 from the leading end of said tube, then an adhesive material 13 is coated thereon.

Finally, a case 14 for the detaining part is fixed to the sleeve 11, and a screw 9 for fixation is fitted. A rubber sleeve 16 is put on the case 14 and is fixed to a detaining plate. Since the tensile fibers are sandwiched between the sleeves 10 and 11 and are held press stuck from the outside, the fibers are hard to sag and provide stable detaining force.

Abstract: PURPOSE:To obtain the position of the center of a pattern to be detected precisely even when reflected-beam intensity distribution from the pattern is asymmetrized by processing a synthetic image detection signal by a weighted symmetrical evaluation function. CONSTITUTION:Reflected beams from a wafer-target pattern are detected by a two-dimensional image pickup element, and sent to a computer in a shape that reflected beams are A/D converted by a preprocessing circuit and further converted into one-dimensional detection signal.
