Filed: 1994-07-26
Abstract: PURPOSE:To obtain the subject fiber passing a flame-retardant test of JIS-L specification, free from the generation of a toxic gas and excellent in washing durability by incorporating a polyester fiber with a specific phosphorus- containing compound. CONSTITUTION:This flame-retardant polyester fiber is obtained by immersing and treating a polyester fiber in a solution prepared by dissolving or homogeneously dispersing a phosphorus-containing compound expressed by the formula. The phosphorus-containing compound is attached on the treated fiber in an amount of 23% of weight of the fiber. The obtained fiber is free from the generation of a halogen-containing toxic gas and the deterioration of fiber properties and excellent in washing durability. The flameretardant fiber exhibits a carbonizing area at 45 degree by A-1 method of <=30cm<2> and that by A-2 method of <=40cm<2> and the number of flame contact in a coil method of >=3 in the specification of JIS-L-1091. The flame-retardant compound can be applied in the same bath as dyeing and, accordingly, dyeing and flame-retardant treatment can be performed at the same time.

Abstract: PURPOSE:To suppress the occurrence of curl by varying the angle formed between the line, which is perpendicular to the line connecting the centers of rotation of a fixing roll and a pressure roll and passes the nip part between these rolls, and the line connecting this nip part and the nip part between a pair of eject rolls. CONSTITUTION:A paper eject roll 10 and an inverted roll 11 are arranged on a paper eject side plate 14 which can be turned around a point O1 at which a line l1 connecting the centers of rotation of a fixing roll 2 and a pressure roll 3 crosses the nip part. One end of the paper eject side plate 14 forms a gear 15 and is coupled to a stepping motor 16. The position of a nip part O2 between rolls 10 and 11 to the point O1 can be changed by driving of the motor 16. This extent of movement is expressed with an angle theta formed between a line l2 perpendicular to the line l1 and a line l3 passing points O1 and O2. The angle theta is changed in accordance with outputs of various sensors to suppress the occurrence of curl.

Title: Method for removing chromatic component from liquid
Inventor: WATANABE AKIRA
IPC: C02F3/34
Filed: 1987-07-15
Abstract: PURPOSE:To perform an efficient adsorption, decomposition and removal of chromatic components by inoculating the waste water containing the nonbiodegradable chromatic components such as kraft pulp waste water, night soil, sewage and drainage with penicillium janthinellum. CONSTITUTION:The waste water containing the nonbiodegradable chromatic components such as kraft pulp waste water, night soil, sewage and drainage is inoculated with the strain belonging to penicillium janthinellum which is separated from rotten chips of wood and cultivated in a medium including alkali lignin, humic acid and bile as chromatic components, whereby such chromatic components are rapidly removed from the medium for causing the transparency thereof. Since the mycelium becomes colored as the decolorization of the aforesaid strain proceeds, the removal of most of the chromatic components from the medium is conceivably ascribed to the adsorption thereof to the surface of the mycelium.
