A temperature measuring device comprises: an optical fiber; a metallic protective tube for covering the optical tube to form a metal-covered optical fiber; and a radiation thermometer connected to the metal-covered optical fiber. A heat insulation coating can be formed to cover the protective tube. A level measuring device comprises: an optical fiber; a metallic protective tube for covering the optical tube to form a metal-covered optical fiber; a radiation thermometer connected to the metal-covered optical fiber; transfer device for sending the metal-covered optical fiber to a surface of a molten metal to be measured and retracting to wind the metal-covered optical fiber from the surface; and level determination device for determining a level of the surface of the molten metal based on a temperature change detected by the radiation thermometer and an amount of feed of the optical fiber through the transfer device.

A noise isolation sheet is installed in a car door that includes a door inner panel and an interior door trim. The door trim is provided inside the door inner panel. The noise isolation sheet partially or wholly covers the door inner panel. The noise isolation sheet has at least two layers including an outer side sheet and an inner side sheet. The outer side sheet includes a first foam body having water absorption of less than 30%, and the inner side sheet includes a second foam body having water absorption of 30% or more.

A glass run 5 fit on a door sash 2 of an automobile has: a cross-section roughly U-shape comprising an outer-cabin side wall 6, an inner-cabin side wall 7 and a connecting wall 18 which connects the outer-cabin side wall 6 and the inner-cabin side wall 7 for guiding a door glass 3 lifting or lowering into a ditch part 4; and an outer lip 9 and an inner lip 10 respectively formed on inner surfaces of both of the side walls 6, 7, which extend toward a connecting wall 18 side and are slidably brought into contact with the door glass 3, wherein: the connecting wall 18 has a part thereof swelled and curved toward an inner surface side thereof, which faces a position on the connecting wall 18 where the door glass 3 collides; the connecting wall 18 swelled and curved has two projections 21, 22 formed on an outer surface thereof, which come into contact with the door sash 2 and of which an interval 50 therebetween is not more than thickness 60 of the door glass 3; and a position surrounded by the two projections 21, 22, the connecting wall 18 and the door sash 2 is formed into a space 40 having a cross-section roughly semicylindrical shape.
摘要:
A method for analyzing steel which comprises: grinding an analysis area of a steel ingot; sealing the analysis area with a sealing section of a cell for generating fine particles; again grinding the analysis area, while an argon gas is introduced into the cell; irradiating a pulsed laser beam of 10.sup.8 W/cm.sup.2 or more onto the analysis area at an irradiating spot of at least 1 mm.sup.2 to generate the fine particles; moving the irradiating spot; and transferring the generated fine particles by the argon gas to a plasma emission analysis for analysis. A further method for analyzing steel comprises: solidifying a molten steel sample, forming a red-hot sample; putting the sample into a sample holding section of a sample chamber under a purified argon gas atmosphere, the sample holding section having an inner curved surface the same as a curved surface of the sample; irradiating a pulsed laser onto the sample to remove a sample surface layer of 25 .mu.m or more of the sample and to generate fine particles from the sample; and exciting the fine particles by a plasma emission analyzer to analyze the composition of the fine particles.

A continuous-casting operation controlling method and apparatus in which: the molten-bath level of molten steel in a mold is detected in a period of from the time point just after the start of injection of the molten steel to the time point when the molten-bath level reaches a molten-bath level for the steady-state operation; and the quantity of discharge of the molten steel is controlled appropriately on the basis of the detected molten-bath level to thereby make it possible to start drawing-out of casting automatically. The molten-bath level is measured continuously by an electrode type molten-bath level meter, so that the molten-bath level ascending rate is obtained on the basis of the change of the molten-bath level. The flow rate of the molten steel discharged from a tundish is adjusted on the basis of the deviation of the molten-bath level ascending rate from a reference rate. When the molten-bath level then reaches a predetermined reference level lower than the molten-bath level for the steady-state operation, drawing-out of casting is started.

A car door structure comprises a door inner panel 11, an interior door trim 12 and a noise insulation sheet 20. The interior door trim 12 is installed in the interior side of the door inner panel 11. The noise insulation sheet 20 is provided between the door inner panel 11 and the door trim 12, where it is hung down from the upper side to the lower side of the door inner panel like a curtain. The noise insulation sheet 20 is fixed to either the door inner panel 11 or the door trim 12. The noise insulation sheet 20 is provided at about an upper half or a lower half of the door inner panel 11, or it is provided at a central part of the door inner panel 11 while dividing approximately into three sections in a vertical direction or a horizontal direction.
