Title: Converter
Inventor: EBISAWA RITSU
IPC: C04B35/043
Filed: 1987-12-18
Abstract: PURPOSE:To improve thermal spalling resistance and to enable the refining of a Cr steel and dead soft steel without having carbon pickup into a product by using unburned MgO-C bricks bonded with a pitch-reformed phenolic resin as lining refractory bricks of a converter. CONSTITUTION:A raw material mixture composed of 5-10wt.% carbon such as graphite and the balance MgO clinker is kneaded with the pitch-reformed phenolic resin as a binder and is molded to a brick shape as the lining refractory brick of the converter. Such bricks are lined without being burned over a part or the entire part of the wall or bottom of the converter. These bricks have the excellent thermal spalling resistance as the MgO and the C forming the bricks do not react with each other even at a high temp. of >=1650 deg.C. An increase in the content of the C by the C pickup from the refractory bricks is obviated at the time of refining the dead soft steel. The chemical attack of the bricks by the drop of the m. p. of the Cr2O3-contg. molten slag by reduction of the Cr2O3 in the Cr2O3 contg. slag by the C in the bricks is obviated as well at the time of refining of the Cr-contg. molten iron.

Title: Heat shock tester
Inventor: TANAKA TAKASHI
IPC: G01N3/30
Filed: 1988-12-19
Abstract: PURPOSE:To enhance test accuracy by repeating the alteration of precooling and preheating temps. on the basis of the return time of the temp. of a test chamber to set temp. CONSTITUTION:The set temp. on a high temp. side and set temp. on a low temp. side of a test chamber are set by a temp. setting device 31. At the time of the changing-over of high and low temps., the return time of the temp. of the test chamber to set temp. due to the temp. sensor 25 of the test chamber is measured by a timer 28. The alteration output of the next precooling temp. of a precooling chamber and the next preheating temp. of a preheating chamber is sent to a heater control means 34 and a cooler control means 37 on the basis of said return time through a precooling and preheating temp. controller 30 to alter precooling and preheating temps. By repeating this operation, the return time to the set temp. can be shortened with good accuracy and, even when the heat capacity of a sample to be tested is different or the atmospheric temp. is varied, energy loss due to overheating and overcooling is reduced.

Title: Electrically warming curtain device
Inventor: KITAZUMI MOTOI
IPC: A47H23/08
Filed: 1987-12-18
Abstract: PURPOSE: To prevent accidental cutting of heater elements and increasing heating efficiency, by providing heating elements composed of flexible plate type electric heater elements to lower part of a curtain. CONSTITUTION: A plate type heating element 11 is composed of flexible conductive polymer material having a width smaller than a distance between curtain hooks 2 and a comparatively short length, and is installed in lower part of the curtain 3. Electrodes 12 are longitudinally arranged along with both sides of plate type heater elements 11, and a lead wire 13 is taken out from the electrodes. By connecting a plug 6 to a power source, expanding the curtain 3, and switching a switch 5 on, the plate type heater elements are heated by electricity. As the plate type heater elements 11 have the characteristics of positive temperature coefficient, the value of electrical resistance increases with temperature rise of the heater, thus the electrical current is restricted and enables self control of temperature.  So, even when the electricity is switched on at the folding condition of the curtain, the equipment is in safe condition without unusual temperature rise.

Abstract: PURPOSE:To prevent aging in ultraviolet-ray intensity due to deposition of reaction products and to obtain equal film characteristics such as a film thickness with almost no decrease in working ratio of an apparatus, by providing a double-window structure at a ultraviolet-ray transmitting window part, and detachably attaching the inner window. CONSTITUTION:An opening part through which projected light of ultraviolet rays from a low voltage mercury 1 is transmitted is provided at a part of an outer bell jar 2. A double structure is adopted for the ultraviolet ray transmitting window part of an inner bell jar 3. Synthetic quartz is used for an outer window 31 and an inner window 32 so that the projected ultraviolet light is transmitted. The two windows 31 and 32 are linked with a cylindrical or squarish tube 7. At this time, the inner window 32 is detachably attached to the tube 7. A gas inlet port 8 for introducing purging gas (a) which does not absorbs the ultraviolet light is provided at the tube. The purging is performed so that a raw material gas is not intruded between the windows 31 and 32. Even if reaction products are deposited on the inner window, the window can be replaced. Therefore, aging of ultraviolet ray intensity due to the deposition of the reaction products can be prevented.
