Title: Production of vinyl chloride monomer by thermal decomposition of 1,2-dichloroethane
Inventor: TEJIMA HIROSHI
IPC: C07C21/06
Filed: 1986-11-29
Abstract: PURPOSE:To reduce the amount of attached coke in the titled method, by carrying out heat exchange of EDC to be fed to a thermal cracking furnace and a high-temperature cracked run-off from the thermal cracking furnace while cooling the cracked run-off gas to a specific temperature and making gas flow velocity of the run-off gas at a specific velocity. CONSTITUTION:In obtaining vinyl chloride monomer by thermally cracking 1,2-dichloroethane (EDC) under pressure, a high-temperature run-off gas from a thermal cracking furnace is subjected to heat exchange with EDC to be fed to the thermal cracking furnace by using a heat exchanger of a structure wherein the cracked run-off gas is cooled to 180-350 deg.C, the flow velocity is 5-20m/s, preferably the cracked gas is circulated to a heat transfer pipe side and liquid EDC is introduced to the furnace in such a way that the heat transfer pipe is dipped in the EDC. Pressure reduction in the heat exchanger carrying out preheating and gasification of EDC is reduced and the amount of coke attached to the heat exchanger can be reduced.

Title: Electron gun unit
Inventor: TAGAWA YASUHIRO
IPC: H01J1/28
Filed: 1986-11-28
Abstract: PURPOSE:To avoid any secular change in an operating characteristic because of sticking of cathode material to an outer circumferential edge of an electron beam transmitting hole so effectively, by covering a shielder on an electron emission surface of the cathode, and limiting an emission part of electron beams out of the cathode, to only an electron beam transmitting hole part of a first grid. CONSTITUTION:This electron gun unit has an electrode group consisting of first to fifth grids inclusive of the first grid having an impregnated type cathode K and an end plate 4 where an electron beam transmitting hole h1 is installed in opposition to this impregnated cathode K. An electron emission surface 3 of the impregnated cathode K is covered with an electron emission shielder 10 for interrupting the electron emission, and a through hole 11a having a diameter phi0 in a part being opposed to the electron beam transmitting hole h1 of the first grid is installed therein whereby electron beams are made so as to be limitedly emitted out of a part of the electron emission surface 3. With this constitution, such a possibility that cathode material, for example, Ba to be evaporated out of the cathode is stuck and accumulated to a peripheral part of the electron beam transmitting hole h1 is effectively avoidable, and simultaneously the incurrence of decrease in an interspace d01 between the first grid and the cathode K is substantially avoidable, thus a secular change in cutoff voltage is remarkably reducible.

Abstract: PURPOSE:To enable cooling of a printing head to be accelerated without contaminating paper, by providing a gap-controlling means for setting a gap at the time of accelerating the cooling of the printing head to be wider than the gap at the time of printing. CONSTITUTION:When an abnormal high temperature condition of a printing head 15 is detected by a head temperature detecting circuit 25, a controlling circuit 22 stops printing by stopping the supply of a printing signal to a printing head driving circuit 24, and then outputs a carriage idle-reciprocation signal to a carriage motor driving circuit 26 to reciprocate the head 15, thereby accelerating the cooling of the head 15. Before the reciprocation of the head 15, the controlling circuit 15 outputs a gap-enlarging signal to a driving circuit 27 for a gap-adjusting motor, thereby widening the gap. Thus, the gap at the time of cooling the head 15 is made wider than that at the time of printing, and the head 15 is reciprocated over the same line on a paper 12, with a sufficient gap therebetween, whereby the head 15 is supplied with an air flow.
