Title: Method for detecting polymerization degree of polyester oligomer
Inventor: SAKAMOTO SEIJI
IPC: C08G63/00
Filed: 1983-05-17
Abstract: PURPOSE:To make it possible to accurately control the final physical properties of polyester by simply and continuously detecting the polymerization degree of an oligomer, by measuring the dielectric constant of the transesterification reaction product of polyester based on polyethylene terephthalate. CONSTITUTION:The dielectric constant of a reaction product or quantity of electricity (e.g., electrostatic capacity) associated therewith is measured by a method wherein a pair of electrodes fixed in a transesterification reaction tank for preparing polyester based on terephthalic acid or lower ester thereof and ethylene glycol or a stirrer and the reaction tank are used as electrodes is measured. Because electrostatic capacity C is represented by formula (wherein K is a proportional constant, epsilon is the dielectric constant of a medium, that is, an oligomer, S is the area of an electrode plates and d is the distance between electrode plates), the tracking of a polymerization degree is enabled by preliminarily calculating the relation of the polymerization degree and the dielectric constant (electrostatic capacity) of the oligomer. By this method, the finish point of transesterification reaction is detected with good accuracy and a polyester solution by the next polycondensation can be accurately controlled and a polymer suitable for a use is obtained.

IPC: G03B27/54
Filed: 1987-04-08
Abstract: PURPOSE:To prevent a fuse from being damaged, by storing a heater, the fuse and a thermistor in a fluorescent lamp cover, allowing the fuse to have looseness, and absorbing a mechanical stress due to a thermal expansion of the cover. CONSTITUTION:A temperature fuse 108 and a thermistor 110 are fixed closely to the reverse side of a fluorescent lamp cover 102 with an adhesive 113. Also, insulating tapes 106, 109 are placed thereon and fixed. In this state, by the thermistor 110, a current to a heater is controlled, and also, by cutting of the temperature fuse 108, the runaway of a temperature rise is prevented. At that time, when the cover 102 is brought to a thermal expansion, the temperature fuse 108 is drawn and cut, therefore, by providing a folded part 116 on the temperature fuse 108, a mechanical stress is absorbed. Accordingly, since the part for absorbing the mechanical stress is provided on the temperature fuse, damage of the temperature fuse caused by a thermal expansion of the cover due to heating of a fluorescent lamp can be prevented.
