Title: Foamed polystyrene product and its production
Inventor: FUJIMORI TAKASHI
IPC: B29K105/06
Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To provide a foamed polystyrene product capable of preventing the generation of black smoke on combustion, capable of improving heat resistance and capable of inhibiting the thermal contraction deformation of the foamed product. SOLUTION: Styrene beads are mixed with a boric acid-based inorganic substance, preliminarily foamed and subsequently left to age. The prefoamed beads are mixed with a boric acid-based inorganic substance and a thermosetting resin, and then mainly foamed. The surfaces of the foamed polystyrene beads 2 of the foamed polystyrene product 1 are thus coated with the coating films 3. When heated, the coating films 3 inhibit the combustion of the polystyrene beads 2. When heated with a large quantity of heat, the coating films 3 are changed into glassy coating films to prevent the deeper combustion of the polystyrene beads 2. The glassy coatings absorb black smoke to prevent the generation of the black smoke.

SOLUTION: When an AC current flows across the counter electrodes 5a, 5b in the ink boiling chamber 2 communicating with a common ink chamber 8 through conductive ink 1, an ink droplet 13 is discharged from a nozzle hole 3 by the pressure of boiling bubbles 12 generated between the counter electrodes 5a, 5b. In this case, a negative voltage is applied to a control electrode 15 through a control circuit 17 when the electrodes are not energized so that ink potential immediately before the start of erergization of the counter electrodes 5a, 5b becomes always constant.  At the time of the application of this voltage, the current on the control electrode 15 is restricted only in the direction from the conductive ink 1 to the control electrodes 15 by a rectifier of the control circuit 17 and, by this constitution, reduction at the counter electrodes 5a, 5b current is suppressed while the electrodes 5a, 5b are not energized.

Then the appearance frequencies of words of registered document information are calculated by the classifications. Thus, one image is divided to increase the probability of an image representing a single body and the kind contents of images can be increased.
