    • A method for continuously measuring the surface temperature of a heated steel strip, includes providing a flat reflecting plate so as to face a heated steel strip at an angle of inclination (.alpha.) with the steel strip. A radiation thermometer measures the amount of heat radiation energy which is emitted from an arbitrary point on the surface of the steel strip and comes directly into the radiation thermometer; and the thermometer also measures the total sum of heat radiation energy which (a) is emitted from a different point on the surface of the steel strip and comes into the radiation thermometer after having been reflected at least twice between the steel strip and the reflecting plate and, (b) is emitted from a final reflecting point, on the steel strip, of the heat radiation from said different point. The emissivity of the steel strip is computed on the basis of said total sum of the energies of the heat radiations and the amount of energy of the heat radiation from the arbitrary point; and the surface temperature of the steel strip is measured on the basis of the computed emissivity and the amount of energy of a reference heat radiation. The final angle of reflection (.theta.) from the steel strip of the heat radiation from said different point, and the angle of inclination (.alpha.) of the reflecting plate, are set at values which satisfy specific limits.

    • 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.
    • 提供了一种热熔体施加器,其包括(a)喷嘴开口,(b)设置在喷嘴开口上游的阀座,(c)形成在喷嘴开口和阀座之间的空腔,(d)阀体 可移动到阀座,使得阀座打开或关闭,和(e)用于偏压阀体的弹簧; 以及用于驱动弹簧的气动驱动气缸。 阀体成形为具有面向喷嘴开口的顶角的锥体,阀座形成有与锥体接触的锥形表面。 锥形表面的角度大于锥体的顶角,并且具有至少1mm的长度。 热熔胶器采用气动驱动气缸驱动阀体,从而压缩弹簧,弹簧又压缩阀体,从而避免了与大容量弹簧相比的热熔胶的极大阻力。 通过稍微改变阀体和阀座的角度,可以防止当阀门关闭时发生的泄漏。 通过将与阀体接触的阀座的锥形表面的长度设定在1mm至2mm的范围内,本发明使得可以防止用于具有大的胶的胶丝长度 粘度如热熔。 此外,将阀体的行程设定在0.3mm至0.5mm的范围内,确保更有效地防止了胶丝的制造。

    • In a high prrecision PLL circuit arrangement, a phase detecting circuit produces a detecting signal which is directly proportional to a phase difference between a horizontal synchronizing signal and a voltage-controlled oscillating signal. A loop filter circuit produces a delay signal for delaying a frequency control at a predetermined time constant in response to the detecting signal derived from the phase detecting circuit. A voltage-controlled oscillating circuit produces an oscillating signal having a frequency directly proportional to a voltage of the delay signal from the loop filter circuit. A non-linear circuit includes a non-linear element for changing at least one of an AC gain and a DC gain of the loop filter circuit, and prevents an erroneous capture phenomenon of the PLL circuit arrangement in response to the detecting signal from the phase detecting circuit.

    • A vertical deflection circuit used in a cathode ray tube display device for shortening a vertical blanking period is disclosed which includes back-flow blocking diode means for preventing an oscillating current from flowing backward to a vertical push-pull output amplifier circuit in the vertical blanking period, resonating capacitor means, and electrostatic energy supplying means for energizing a fly-back pulse. The resonating capacitor means is provided to generate resonance due to the capacitance of the capacitor means and the inductance of a vertical deflection coil, on the basis of the electro-magnetic energy of the vertical deflection coil at a time immediately before a retrace line starts from the bottom of display screen, thereby producing a fly-back pulse. The back-flow blocking diode means prevents the fly-back pulse from flowing backward to the vertical output circuit, that is, prevents the fly-back pulse from de-energizing the output of the vertical output circuit. According to the above vertical deflection circuit, the power consumption in a vertical retrace operation is reduced, and a ratio of the vertical blanking period to a vertical scanning period can be made small. Accordingly, an effective scanning time is increased, and it becomes possible to display information precisely.
