Title: Manufacture of polyester composition
Inventor: TATSUMI HIROAKI
IPC: C08L67/00
Filed: 1993-05-18
Abstract: PURPOSE:To obtain a polyester composition excellent in dispersion, by a method wherein in a kneading machine provided with a vent hole, inert gas is added to polyester containing particles in a molten state. CONSTITUTION:Polyester containing particles which is obtained by allowing the polyester such as polyethylene terephthalate to contain an inorganic particles or an organic particles such as titanium oxide or a styrene-divinylbenzene copolymer is supplied to a kneading machine provided with a vent hole in a solidified state such as a chip or a molten state and made into a molten state directly before addition of the inert gas. Then, the polyester prepared by continuous polymerization may be supplied to the kneading machine provided with the vent hole as it is in the molten state. The partiles are supplied under a state of powder or slurry or a master polymer. Then, it is necessary that the inert gas is added in the kneading machine provide with the vent hole. Hereby, dispersion of the particles agglomerated firmly becomes possible. Then shearing heating becomes low and a fall of intrinsic viscosity and a color tone are almost eliminated.

IPC: E05F1/06
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To simplify the structure of an automatic door opening/closing device and reduce cost by providing a pair of hinges at a door body and a fixed body such as a wall. SOLUTION: When a door body is opened by a specified angle from the closed state to a fixed body 2, a hinge 6 is shifted upward while being rotated around a hinge shaft 7 so as to form a clearance S between a joint face 5b of a bearing part 5a and a joint face 6b of a bearing part 6a. When the door body 3 is opened in the shifted-up state of the door body 3, the own weight of the door body 3 is applied to the hinge 4. This load from the door body 3 imparts downward turning force to the hinge 4, so that the door body 3 is rotated in such a way as to be automatically returned into the original position by this turning force. The joint face 5b of the bearing part 5a and the joint face 6b of the bearing part 6a are thereby returned into the contact state to close.

Filed: 1982-07-05
Abstract: PURPOSE:To analyze many elements from a small amt. of sample by the atomic absorption spectrochemical analysis, by specifying an amt. of sample soln. to be sprayed with an atomizer per one analysis. CONSTITUTION:Atomic absorption spectrochemical analyses were repeated in 9 times by changing an amt. of sample contg. 10ppm Zn to be sprayed per one analysis to 30, 50, 100, 200, 300, 400, an 500mul, and using different vessels of A, B, C, D, and E. It was found from the relationship between the wave heights and fluctuation coeffts. obtained at each analysis that the range of 200-500mul spray amt. gave sufficient accuracy and sensitivity. Since a necessary amt. of sample to be sprayed per one analysis is <=1/10 the amt. sprayed per one conventional analysis, so many elements can be analyzed in a small amt. of sample. When a sample soln. is prepd. from the same sample, a concn. rate can be raised to >=10 times to enhance accuracy of analysis.

Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To prevent a discharge from occurring in a place where it should not. SOLUTION: A magnetron is connected to a waveguide 56 and microwaves emitted by the magnetron are guided. A fixed member 54 has between the end 571 of the top plate 570 of a heating chamber 50 and an antenna shaft 53 a shield part 540 for shielding the end 571 from the antenna shaft 53. The thickness of the top plate 570 is about 0.4 mm. The shield part 540 is extended about 5 mm above the end 571 in order to surely shield the end 571 of the top plate 570. Therefore, foreign matter such as fragments of solder is unlikely to enter between the end 571 and the antenna shaft 53. Even if such foreign matter has entered, a discharge at that site does not occur since the end 571 is shielded by the shield part 540 from the antenna shaft 53.
