Title: Production of polyethylene
Inventor: FUKAWA ISABUROU
IPC: C08F10/02
Filed: 1983-03-28
Abstract: PURPOSE:To produce polyethylene by deactivating a catalyst by adding a specified deactivator to an ethylene polymer mixture produced at a high temperature in the presence of a specified polymerization catalyst and separating unreacted monomer. CONSTITUTION:Ethylene or a mixture of ethylene with 3-18C alpha-olefins is polymerized under conditions including an average polymerization temperature >=130 deg.C by using a coordination polymerization catalyst containing a transition metal compound (e.g., a Ti or V compound) and an organometallic compound (e.g., an organoaluminum compound) in the presence or absence of an inert hydrocarbon solvent. To deactivate the catalyst, a polyether compound (derivative), e.g., polyethylene glycol, as a deactivator is added to the produced polymerization mixture. Unreacted monomer is separated from the produced polymer mixture to produce polyethylene. The above deactivator itself is not volatile nor forms any volatile reaction product when reacted with the catalyst, so that there is no risk of contamination of the recovered monomer or solvent.

Title: Manufacture of hermetic-coat optical fiber
Inventor: MIYAMOTO SUEHIRO
IPC: C03C25/10
Filed: 1988-03-07
Abstract: PURPOSE:To fix the linear speed of optical fibers so as to realize a uniform coating which is free from unevenness in film thickness in the length direction of the fibers by not performing the hermetic coat to the fibers in tandem with a spinning (wire drawing) process, but as a separate process. CONSTITUTION:In order to prevent optical fibers just wire-drawn from being scratched, the fibers are first covered with an ordinary coating material immediately after they are wire-drawn, thereafter, hermetic coat is performed on the fibers after the coating material is removed by means of a non-contacted means in another process. The above-mentioned non-contacted means means heat- resolution performed on the coating material covering the fibers and, as occasion demands, a removing means using an etching gas is added to the heat-resolution. In other words, the hermetic coat is performed on the optical fibers 1 by means of a coating device 4 of a process which is different from the spinning (wire- drawing) process. Therefore, control of the feeding speed of the optical fibers 1 becomes unnecessary in the coating process since the control of the outer diameter of the fibers is already performed in the spinning process. As a result, unevenness in the thickness of the coating thin film caused by unevenness in speed can be eliminated and a uniform thickness is obtained.

Abstract: PURPOSE:To continuously transfer a resources between different options by providing a resources control table to prepare two entires for each resources, and expressing the occupying state of one resources by one or two entries in correspondence to the kind of the option. CONSTITUTION:When it is requested to occupy the resources, the occupying state of the resources is determined by retrieving the two entries maximally out of a table 3.
