Title: Production of heat-resistant resin foam
Inventor: FUWA HIDEO
IPC: C08J9/06
Filed: 1987-04-22
Abstract: PURPOSE:To obtain a uniform foam of a high-melting heat-resistant resin such as a thermoplastic resin, by mixing the heat-resistant resin with an alkali metal oxalate and melt-processing the mixture. CONSTITUTION:A heat-resistant resin is mixed with an alkali metal oxalate, and the obtained mixture is melt-processed to obtain the purpose resin foam. The thermoplastic resin used is a heat-resistant resin which is a high-melting thermoplatic resin and has a resin melting temperature of 330-450 deg.C. Examples of these resins include polyoxybenzoyl, its copolymers and polyether ether ketone. This foam can be obtained by adding a blowing agent to such a resin during its molding and melt-processing the mixture. Examples of the blowing agents used include alkali metal oxalates, especially, sodium and potassium salts. When the melting temperature of the resin is below 350 deg.C, said oxalate can not be decomposed during processing, and when that of the resin is above 450 deg.C, the salt decomposes before the resin is molten. Therefore, no foam can be obtained in these cases.

Title: Method of stopping and starting air spinning machine
Inventor: HONJIYOU TAKEO
IPC: D01H15/00
Filed: 1978-08-09
Abstract: PURPOSE:When the spinning machine stops, the air supply to the air nozzle is lastly stopped and then the operations restarts from the air supply whereby the start of the air spinning machine is mode under the best conditions. CONSTITUTION:When the machine is stopped, the roller-driving system is switched off to cause the break of slivers in the air nozzles by spinning, then the air supply is discontinued when the yarns on all spindles break. On the restart, the operations are initiated with the supply of air to nozzle 7, then the roller-driving system is switched on to start the sliver supply. At this time, as spun yarns are in break, they are continuously sucked in pipe and the signals of yarn break are dispatched from all the positions. Thereby carriage 14 with rnotter starts to operate and does yarn ending at each position. Since slivers and waste yarns do not collect inside and around nozzles and the yarn ends are wound on the packages, the sure pick- finding can be done.

Filed: 1987-04-21
Abstract: PURPOSE:To obtain a composite dielectric with a specific dielectric constant which is suitable for a capacitor of minute capacitance by composing this dielectric of a group BaO-TiO2-Nd2O3-PbO dielectric ceramics and an insulating high-molecular material end next by specifying contents of the dielectric ceramics and the insulating highmolecular material. CONSTITUTION:This dielectric is composed of a group BaO-TiO2-Nd2O3-PbO dielectric ceramics A and an insulating high-molecular material B. Contents of A and B are in the ranges of 10 to 70 capacity % and 30 to 90 capacity %, respectively, to the total capacity of A+B. When the content of the dielectric ceramics is less than 10 capacity % or that of the insulating high-molecular material is in excess of 90 capacity %, its specific dielectric constant does not increase. On the other hand, when the content of the dielectric ceramics is in excess of 70 capacity % or the insulating high-molecular material is in less than 30 capacity %, the amount of the dielectric ceramics is too large to obtain a homogeneous composite dielectric. This dielectric can be hence possessed of a specific dielectric constant which is suitable for a capacitor of minute capacitance, molding performance, and processibility.
