摘要： PURPOSE:To accurately measure the size of an article by stabilizing the sizing clock on the basis of a signal from an image sensor and the sizing clock having predetermined frequency from a PLL circuit. CONSTITUTION:When an article 14 is irradiated by a light source 15 and the light from the light source 15 is received through the article 14 by an image sensor 1, the sensor 1 produces a signal having a waveform shown in Fig. a. When the signal a is fed through an amplifier 9 and an envelope circuit 10, the circuit 10 produces a signal having a waveform shown in Fig. b. The signal output from the circuit 10 is then applied to a waveform shaper 11, which produces a signal c having pulse width t corresponding to the size of an article 14 to be measured. When the signal from the sensor 1 is, on the other hand, applied to a PLL circuit, the circuit produces a sizing clock having predetermined frequency shown in Fig. d from a variable frequency oscillator 6. When the output from the shaper 11 and the output from the oscillator 6 are then applied to an AND gate 14 as shown in Figs. c and d, the AND gate 14 produces a signal e having pulse number corresponding to the width of silver plated portion 18. The pulse number is counted by a counter 15 to measure the width of the portion 18.

摘要： PURPOSE:To set a certain level of reference voltage for each element to discriminate the presence or absence of a mark, by maximizing the level difference between the presence and absence of the mark with a simple circuit constitution in which a controlling resistance in series to a CdS. CONSTITUTION:A CdS, i.e., a photoconductive element is used as a sensor 14, and a controlling resistance is connected in series to the CdS to correspond to a code mark. These CdSs and resistances are arrayed in a matrix in correspondence to the code marks. With such controlling resistances, the difference of voltage levels between the presence and absence of the code mark is maximized regardless of the variance of the resistance value of each CdS. Thus the reference voltage is set constant for a comparator 16 that discriminates the presence or absence of the code mark. This reference voltage is obtained by a reference voltage sensor 15.

摘要： PURPOSE:To measure the plated state of an article on which surface is not partially plated on the basis of a sizing clock having predetermined frequency from a PLL circuit and of a signal from an image sensor. CONSTITUTION:Light rays are irradiated from a light source 19 to a flat article 16 on which silver is plated on the portion 18 on the surface of a copper plate 17. When the reflected light rays are applied to an image sensor 1, a signal having a waveform shown in Fig. a is produced from the sensor 1, because the reflectivities of the copper plate 17 and the silver plated portion 18 are different. When the signal a is fed through an amplifier 9 and an envelope circuit 10, the circuit 10 produces a signal having a waveform shown in Fig. b. When the output of the circuit 10 is applied to a waveform shaper 11, the shaper 11 prlduces a signal c having a pulse duration t corresponding to the width of the portion 18. When the signal output from the sensor 1 is applied, on the other hand, to a PLL circuit 2, the circuit 2 generates a sizing clock having predetermined frequency shown in Fig. d from a variable frequency oscillator 6. The output from the shaper 11 and the output from the oscillator 6 are applied then to an AND gate 14 as shown in Figs. c and d. Thus, the AND gate 14 produces a signal e having pulse number corresponding to the width of the portion 18. The pulse number is counted by a counter 15 to measure the width of the portion 18.

摘要： PURPOSE:To perform accurate, high-precision flaw discrimination through simple constitution, by permitting a monostable multivibrator, an AND gate, etc., to discriminate the successive generation of two scanning pulses of the opposite polarities which correspond to a flaw. CONSTITUTION:A flat plate streak 4 having a beltlike plated part 1, etc., is scanned widthwise, and pulses x1-, and y1- of the polarities which correspond to rising stage parts and falling stage parts are detected by an optical sensor 10 and a signal processing circuit 11 to detect successive pulses x2 and y1, y3 and y4, etc., of the different polarities from projecting and recessed flaw parts 2 and 3, etc. Those pulses trigger monostable multivibrators 13 and 14 through a threshold device 12. Then, outputs of the monostable multivibrators 13 and 14 and detection pulses of the other polarity are ANDed by AND gates 15 and 16 to discriminate the succession of detection pulses of the different polarity, thus detecting the presence of flaws. Therefore, a digital switch, a counter, etc., are unnecessary and accurate, high-precision flaw discrimination is performed through the simple constitution of the monostable multivibrators, AND gates, etc., without any erroneous detection.

摘要： PURPOSE:To improve the inspection precision of the surface condition of a body by finding in order the difference between an original signal and a plurality of delay signals formed from the original signal in order to obtain a response signal even from a defect of a gentle change. CONSTITUTION:A light-receiving device 32 outputs a signal (a) which has a response part (A) corresponding to a sharp defect 34 and a response part (B) corresponding to a gentle defect 34'. The signal (a) is sent to an amplifier 9 and an envelope circuit 10 to obtain a signal (b), which is provided with delays in delay circuits 111, 112, and 113 to obtain signals (e), (f), and (i) respectively. The difference between the signals (e), (f), and (i) and the original signal (b) is subtracted from the signals (e), (f), and (i) in differential amplifiers 121, 122, and 123 to obtain signals (d), (g), and (j) respectively. The signal (e) having a pulse (C) corresponding to the sharp defect 34 is obtained from the signal (d), a signal (h), from the signal (g), and a signal (k) having a pulse (D) corresponding to the gentle defect 34', from the signal (j). The signals (e), (h), and (k) are transmitted to an OR circuit 16 to obtain a signal l having the pulses (C) and (D) corresponding to the defect part.

摘要： PURPOSE:To perform connection of strands in stranded wiring work simply and in a short time regardless of the diameter of strand by connecting the end part of a strand being stranded to the tip of a new strand with a thin metallic tube to stake the both ends. CONSTITUTION:A positioning groove 3 that protrudes into the hollow part is provided at the middle part of the sleeve having a thin hollow inside metallic tubular shaped body. Opposed ends of a pair of strands 4, 4 to be connected are inserted into the hollow part until the ends come into contact with the groove 3. Connection of the two strands is achieved by staking 5, 5... on both longitudinal sides of the positioning groove 3 of the sleeve 1. Working time for connection of strands during stranded wiring work can be reduced remarkably by preparatory planning in inserting the tip of a new strand 4 into the sleeve 1 to be stacked as specified.
