Inventor: HIRONAKA TADAO
IPC: C21C5/46
Filed: 1992-07-10
Abstract: PURPOSE:To remove the metal stuck to the furnace opening part in a converter within short time. CONSTITUTION:This device is composed of a lance 1 having holes injecting oxygen sideward at the lower part and a lifting track 2 ascended/descended by fitting this lance, and a hollow shaft 5 rotated by a driving device is connected to the upper part of the lance through a rotary pipe joint 4.

The layer insulation paper 22 has a width nearly the same as the coil width and the part of the paper becomes underlay of the wire 1 of the 2nd layer to be wound later and thus is inserted between the 1st and the 2nd layers. The rest part of the paper 22 is overlapped on the wire 1 of the 2nd layer already wound and thus inserted between the 2nd and the 3rd layers. A larger number of sheets of layer insulation paper are laminated to the side of higher layer voltage and the insulation is reinforced. The same manner can be repeated on the 3rd layer and after and the insulation with excellent properties can be obtained economically.

Abstract: PROBLEM TO BE SOLVED: To prevent S/N deterioration by color and to prolong the life of a lamp by previously applying early deteriorating one of fluorescent materials by a little more quantity in consideration of the difference in the deterioration characteristic of the light emitting intensity of the fluorescent materials of three colors in a three-wavelength type fluorescent lamp, so as to nearly equalize the life due to the deterioration of the fluorescent materials of the three colors to nearly equalize the RGB output level of CCD.
