    摘要: A production process for heat-expanded microspheres comprising the step of providing a gaseous fluid containing heat-expandable microspheres, which comprise shell of thermoplastic resin and a blowing agent encapsulated therein having a boiling point not higher than the softening point of the thermoplastic resin and have an average particle size from 1 to 100 μm, feeding the gaseous fluid through a gas-introducing tube having a dispersion nozzle on its outlet and being fixed inside a hot gas flow, and emitting a jet of the gaseous fluid through the dispersion nozzle; a step wherein the gaseous fluid is collided on a collision plate fixed under the dispersion nozzle so as to disperse the heat-expandable microspheres in the hot gas flow; and a step wherein the dispersed heat-expandable microspheres are heated in the hot gas flow at a temperature not lower than their expansion initiating temperature and thus expanded. The production process results in minimum difference in the variation coefficient of particle size distribution between the microspheres before and after heat-expansion, slight ratio of raw microspheres and slightly expanded microspheres contained in resultant heat-expanded microspheres, and suppressed formation of aggregated microspheres.

    摘要: The present invention provides thermo-expansive microspheres comprising thermoplastic resinous shell and a blowing agent being encapsulated in the shell, the blowing agent which is a fluorine-containing C2-10 compound having ether linkage, being free of chlorine and bromine atoms and gasifying at a temperature not higher than the softening point of the thermoplastic resin; and also provides the production and application processes thereof. The thermo-expansive microspheres have preferably an average particle size ranging from 1 to 100 μm and a CV, or coefficient of variation, of particle size distribution being 30% or less, and a retaining ratio of blowing agent encapsulated being 90% or more. The thermo-expansive microspheres have low environmental loading and superior flame-retardant or flame-resistant performance, and have particle sizes distributing in narrow ranges. Those thermo-expansive microspheres and foamed hollow microspheres are suitable for applying to fire-proof paints, flame-retardant or flame-resistant thermo-insulating materials, flame-retardant or flame-resistant lightweight fillers, and flame-retardant or flame-resistant lightweight molded products, in addition to the conventional application field.

    摘要: A jitter correcting system is provided in a video reproducing apparatus for reproducing a composite video signal of a given standard television system to be connected to a monitor television receiver including an automatic frequency control for a horizontal oscillator, comprising a circuit for phase modulating the horizontal synchronizing signal of the reproduced composite video signal, by the amount associated with the phase difference between the composite video signal to be applied to the picture tube of the monitor television receiver and the output signal of the automatic frequency control of the monitor television receiver, for providing a modified composite video signal a phase modulated horizontal synchronizing signal. The system further comprises a circuit for generating a pseudo video composite signal including vertical and horizontal synchronizing signals and a marking signal in the video signal phase region wherein the horizontal synchronizing signal has been phase shifted as compared with that of the standard television system of the video reproducing apparatus for applying the said pseudo composite video signal through the jitter correcting system to the monitor television receiver, whereby the phase modulating circuit can be adjusted while observing the marking indication caused by the marking signal appearing on the screen of the picture tube.

    摘要: The present invention provides a temperature-indicating sheet which, when exposed to temperatures higher than the prescribed temperature in temperature-control for the common low-temperature preserved goods, changes in color according to the exposure temperature and time. This object is attained by arranging one component which melts at the prescribed temperature and a substance which irreversibly changes in color in contact with said component through a membrane permeable to the component. The sheet of the present invention comprises a component which melts at the prescribed temperature, a substance which changes in color in contact with the component and a membrane permeable to the molten component, said component being included in microcapsules which can be broken by outer pressure at a temperature used, and in which the component and the substance are arranged at the opposite sides with respect to the membrane.
