摘要： An apparatus for measuring the temperature of a metallic body in a non-contact maner includes an electronic circuitry for measuring a change in the impedance of a detecting coil arranged oppposite to the metallic body. The electronic circuitry comprises an operational amplifier, a negative feedback circuit with adjustable feedback factor, a positive feedback circuit, an oscillator, a phase shifter circuit and a synchronous detection circuit. The change in the impedance of the detecting coil is caused by the effect of eddy current produced by the application of alternating field to the metallic body, and this impedance change is dependent on change in the temperature of the metallic body. By adjusting the negative feedback factor .beta..sub.N of the negative feedback circuit and the phase angle .theta. of the phase shifter circuit in the electronic circuitry, the relationship between the distance measured between the detecting coil and the metallic body and the measured output level, the temperature measuring sensitivity relative to the temperature of the metallic body and the temperature measuring sensitivity relative to the measuring distance can be determined as desired.

摘要： In measuring the distance between a measuring sensor and a metallic body, the sensor is comprised by a resonance circuit including a capacitor and a coil, and the sensor is connected to the input of a Q multiplier circuit which is impressed with an AC signal having a predetermined frequency. The non-linear distance-inductance characteristic of the coil is compensated for by adjusting the selectivity of the resonance circuit so that the amplifier included in the Q multiplier circuit produces a linear output. Such compensation is performed by adjusting the gain and/or the amount of positive feedback of the Q multiplier circuit.

摘要： The detector comprises a reference AC signal generator with one terminal grounded, a feedback amplifier having one input connected to receive the reference AC signal; a feedback network coupled to the output of the feedback amplifier, the other input of the feedback amplifier, and the grounded terminal so as to supply a feedback voltage between the grounded terminal and the other input of the feedback amplifier; and a detector for detecting the output of the feedback amplifier. The feedback network includes two serially connected detection coils spaced in the direction of movement of a metallic member to be detected to vary their impedances in accordance with the variation in the electric or magnetic characteristic of the metallic member. Further, the pair of detection coils are arranged such that when the homogeneous portions of the metallic member pass by these coils they provide a substantially constant feedback ratio whereas when a portion having electric or magnetic characteristic different from those of the homogeneous portions passes between the detection coils, the inversion between a larger feedback ratio than the constant value and a smaller feedback ratio than the constant value is obtained, thereby detecting the position of the portion to be detected.

摘要： There is disclosed a molten metal level monitoring and controlling apparatus for continuous casting machines which employs an eddy-current type distance measuring device for measuring the level of the molten metal in the mold of a continuous casting machine. The eddy-current type distance measuring device generates a molten metal level signal by detecting in a noncontact manner the distance between its detecting mechanism fixedly mounted in place just above the surface of the molten metal and the molten metal level. According to another embodiment of the invention, the detecting mechanism of the eddy-current type distance measuring device is arranged so as to be vertically movable just above the surface of the molten metal, whereby the detecting mechanism is moved in response to variations in the level of the molten metal to always maintain constant the distance of the detecting mechanism from the molten metal level, and the potentiometer attached to the detecting mechanism generates a molten metal level signal indicative of the distance travelled by the detecting mechanism. The thusly generated molten metal level signal is displayed on a recorder and it is also used for adjusting the pouring rate and the casting withdrawing rate through a monitoring and controlling mechanism so as to maintain the level of the molten metal in the mold within a predetermined range.

摘要： There is provided a hot melt applicator including (a) a nozzle opening, (b) a valve seat disposed upstream of the nozzle opening, (c) an empty chamber formed between the nozzle opening and the valve seat, (d) a valve body movable to the valve seat so that the valve seat is open or closed, and (e) a spring for biasing the valve body; and a pneumatically driven cylinder for driving the spring. The valve body is shaped to be a cone having an apex angle facing the nozzle opening, and the valve seat is formed with a tapered surface which is to make a contact with the cone. The tapered surface has an angle greater than the apex angle of the cone, and has a length of at least 1 mm. The hot melt applicator uses a pneumatically driven cylinder for driving the valve body to thereby compress the spring which in turn compresses the valve body, and thus, avoids the great resistance of hot melt with the spring used as a large capacity. By slightly changing angles of the valve body and the valve seat, the leakage which would occur when the valve is closed is prevented. By setting a length of the taper surface of the valve seat which is to make contact with the valve body to be in the range of 1 mm to 2 mm, the present invention makes it possible to prevent making of glue filament for a glue having great viscosity such as hot melt. In addition, setting a stroke of the valve body in the range of 0.3 mm to 0.5 mm ensures more effectively to prevent making of glue filament.
