Title: Thermal recording medium
Inventor: MATSUI TAKESHI
IPC: B41M5/28
Filed: 1989-04-22
Abstract: PURPOSE:To obtain a recording image having high density and high freshness with excellent resolution and fine printing energy by employing a synthetic resin film layer having a specific range of content of fine cavities as one component of the support of a thermal recording layer. CONSTITUTION:The content of the fine cavities of a synthetic resin film layer provided underneath a thermal recording layer is 40-100cc/100g. In order to obtain the film having the above fine cavities, synthetic resin and substance insoluble in the synthetic resin are mixed, melted, and extruded to obtain an unoriented film. Then, when it is sequentially oriented biaxially, the insoluble substance become nuclei at the time of orientation, and cavities are generated in the orienting direction. In this case, the higher the orientation magnification is, or the lower the orientation temperature is, the more the quantity of generated cavities tends to be increased. Thus, the orientation magnification and temperature are so regulated as to become the content of the cavities as described above. Polyolefin is recommended as the resin to be used in view of suitable cushioning properties, easiness of film formation, stability for moisture, no generation of chlorine at the time of incineration, and economy.

Title: Purification of aliphatic isocyanate
Inventor: AIGA MAKOTO
IPC: C07C265/14
Filed: 1982-06-17
Abstract: PURPOSE:To purify the titled compound in high purity, and to suppress the discoloration of the compound, by distilling out the solvent after the reaction of an aliphatic diisocyanate to obtain a concentrated liquid having a specific solvent concentration, removing the tar component from the liquid, and heating the product within a specific temperature range. CONSTITUTION:An aliphatic diamine or its hydrochloride is made to react with phosgene in the presence of an inert organic solvent (e.g. o-dichlorobenzene) to obtain the corresponding aliphatic diisocyanate (e.g. hexamethylene diisocyanate). The solvent in the obtained reaction mixture is distilled out to obtain a concentrated diisocyanate solution containing 10-50wt% of solvent. After removing the tar component from the solution, the solution is heat-treated at a temperature between the boiling point of the residual reaction solvent and the point lower than the boiling point by 30 deg.C, and fractionated. The colored components in the liquid to be purified can be converted to polymeric tar and removed. By combining the tar-removal process, the present process enables to suppress the colored impurities produced by the decomposition of tar during the heat-treatment.

Title: Method for measuring magnetite concentration in flash smelting furnace slag
Inventor: IEMORI NOBUMASA
IPC: G01N33/20
Filed: 1985-05-14
Abstract: PURPOSE:To measure quickly the magnetite content in flash smelting furnace slag by measuring the oxygen partial pressure in said slag, correcting the same with respect to a prescribed temp. to obtain a standard value, substituting said value and the weight ratio of Fe/SiO2 into a prescribed equation and making calculation. CONSTITUTION:The oxygen partial pressure in the slag discharged from a flash smelting furnace or the flash smelting furnace slag discharged from a smelting furnace is measured by using a probe contg. an oxygen concn. cell. The value is then standardized to the oxygen partial pressure at the predetermined temp. and the corrected value is determined as the standardized oxygen partial pressure (logPo2). The slag is analyzed by fluorescent X-rays, etc. and the weight ratio of Fe/SiO2 is determined. These values are substd. into the equation (where %FeO1.5, %FeO denote the weight % of Fe2O3 and FeO and X, Y denote constants), by which the magnetite content is determined. Since the weight ratio of Fe/SiO2 is controlled constant at all times, the magnetite concn. is measured quickly simply by measuring the oxygen partial pressure.
