IPC: G03C1/52
Filed: 1988-07-15
Abstract: PURPOSE:To improve storage stability and to enhance heat sensitivity by containing a specific diazonium compound and an org. basic compound melted by heat to become basic as a coupler in the photosensitive thermal layer provided on a support. CONSTITUTION:A diazonium compound represented by formula (wherein X is an alkali salt of sulfonic acid and n is 1-3) and an org. basic compound melted by heat to become basic as a coupler are contained in the photosensitive thermal layer provided on a support. Since only the diazonium compound component and the coupler component are present in the thermal recording material thus constituted during preservation before use, even if said recording material is heated by mistake, no color is formed and the storage stability thereof is good. Further, the diazonium compound represented by the formula shows a property generating photodecomposition by the irradiation with light to form a coupler having a naphthol skeleton. Therefore, by subjecting this thermal recording material to pre-exposure by irradiating the same with light of 5-30mJ/cm<2> before recording, the coupler having the naphthol skeletal is generated. As a result, when an imagewise heat pattern is imparted to the thermal recording material by directly heating a thermal head, the alkali generating agent of the heated part is melted to form a basic atmosphere and a good azo dye image 7 is obtained by the coupling reaction of the diazonium salt with the coupler having the naphthol skeletal.

Filed: 1993-06-24
Abstract: PURPOSE:To effectively and certainly wash a circulating line by filling the circulating line with water and supplying air to the circulating line from the lowermost part thereof to discharge the water in the circulating line. CONSTITUTION:After a circulating line 3 is filled with water, a valve 13 is closed and the valve 12 at the lowermost position is opened to send air into the circulating line 3. Water becomes a bubbling state by sending air into the circulating line 3 and vibration is transmitted to the polymer particles remaining in the circulating line 3 through the water in the line 3 and the polymer particles become a state floated from the wall surface of the circulating line 3 to be easily removed. After air is supplied, a lower valve 11 is opened to discharge the water in the line 3 at a stroke to easily remove the polymer particles in the circulating line 3. By this constitution, the washing of the circulating line 3 can effectively and certainly be performed.

Filed: 1982-10-12
Abstract: PURPOSE:To improve the corrosion resistance of an aluminum group wire while maintaining the low cost property of the wire, and to prevent disconnection due to corrosion by using the wire consisting of aluminum, silicon and copper. CONSTITUTION:The wire 6 contains 1-10% Si and 1-10% Cu besides Al. The range of the content of Si is selected because Si itself is hard, the flexibility of the wire lowers when the content exceeds 10%, and an effect of improving the corrosion resistance of the wire by the mixing of Si is not displayed sufficiently when it is less than 1%. On the other hand, the range of the content of Cu is limited because the corrosion resistance of the wire is not improved sufficiently when the content is less than 1%, and the elongation of the wire lowers and corrosion resistance and stress-resisting property deteriorate when it exceeds 10%. According to the composition, the corrosion resistance of the wire is improved largely, and the disconnection of the wire can be prevented.
