IPC: C21C5/46
Filed: 1986-03-25
Abstract: PURPOSE:To accurately and continuously predict the slopping of slag in a converter with a simple and inexpensive apparatus by measuring electric power due to radiant heat having a prescribed wavelength radiated from the slag during refining by blowing and by detecting a change in the electric power. CONSTITUTION:Radiant heat radiated from slag 3 formed on molten steel 2 in the body 1 of a converter during refining by blowing is received by an antenna 7 put on the window 6 of a stack duct 5.

Filed: 1984-04-04
Abstract: PURPOSE:To make a device small-sized by constituting the device with a cabinet provided with a tape driving mechanism, a main cover body where a cassette is stored, and an auxiliary cover body provided with a slide base to which a magnetic head is attached. CONSTITUTION:A tape recorder consists of a cabinet 11, a main cover body 14, and an auxiliary cover body 15. Since a slide base 27 having a magnetic head 29 is attached freely slidably to the auxiliary cover body 15, the slide base 27 is slided and the magnetic head 29 and a pinch roller 19 are retreated not to hinder a cassette 30 from being set into a storage chamber formed with the main cover body 14 and the surface of the cabinet 11 when the cassette 30 is loaded there, and thus, the cassette is easily set there. When the auxiliary cover body 15 is pushed back to the original position after this loading, the head 29 and the pinch roller 19 are moved to the operating position. Consequently, the cabinet 11 is made small-sized because the space required for sliding of the slide base 27 is unnecessary.

Title: Resin molded goods having plating layer and their production
Inventor: KAMIMURA TOSHIYA
IPC: B60K15/04
Filed: 1995-03-27
Abstract: PURPOSE: To provide resin molded goods with which the adhesion strength of plating layers to base materials is improved without degrading the properties of the molded goods and a process for producing these goods. CONSTITUTION: A fuel filler pipe 1 has a pipe body 2 and the plating layers 3 consisting of the electroless plating layer 3A and electroplating layer 3B on the outer side face of the body. The pipe body 2 is formed by using a high- density polyethylene as a principal material and incorporating fillers 11, such as mica, therein. The fillers 11 projecting from the pipe body 2 do not melt at the time of etching and act as start points for formation of the electroless plating layer 3A. The growth of the electroless plating layer 3A is thus accelerated. The formed electroless plating layer 3A provides one kind of chemical bond with the fillers 11 removed of the inert parts of the front layer by the etching in addition to the anchor effect of the fine ruggedness formed by the etching.  The secure bonding strength between the pipe body 2 and the electroless plating layer 3A via the fillers 11 is, therefore, assured.

Title: Method and apparatus for detection of ripples on hot-dip metal bath face
Inventor: EGUCHI NOBUYUKI
IPC: C23C2/00
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To uniformize the plating adhesion amount of a surface-treated steel sheet and perform a detecting operation with high accuracy by a method wherein a linear laser beam is cast on the bath face of a hot-dip metal plating bath inside a face which is at right angles to the face of the steel sheet and which is tilted with reference to the bath face and the wave height and the synchronization of ripples on the bath face are measured on the basis of the image on the bath face of the irradiation beam. SOLUTION: When a steel sheet 3 is pulled up to the verical direction from a hot-dip metal plating bath 1, ripples 6 are generated on a both face 2. In order to measure the shape of a waveform on the bath face, a laser light source 11 which projects a linear laser beam 12 is installed. Since the ripples 6 on the bath face are a wave motion parallel to the steel sheet 3, the laser beam 12 is arranged in such a way that a straight line by which the bath face 2 is crossed with the face of the steel sheet 3 is perpendicular to a straight line by which the bath face 2 is crossed with the linear laser beam 12.  That is to say, a linear-laser irradiation beam is projected onto the bath face 2 inside a face which is at right angles to the sheet face of the steel plate 3 and which is tilted with reference to the bath face 2 (i.e., which forms an angle of inclination 13 with reference to the vertical line). A monitoring range 5 which contains a projected image 14 is imaged by a camera 16 which detects a laser reflected beam 15. An image analyzer 17 computes the wave height and the synchronization of the ripples 6.

Abstract: PURPOSE:To eliminate an unintentional separation by providing a connecting plate having a deformation hole including small and large diameter parts communicating with an opening of an inserting gap on the surface of a pole of a permanent magnet of an attracting tool, providing an overhang collar partly at a ferromagnetic protrusion of a tool to be attracted at its free end side, and providing a gap between the protrusion and a ferromagnetic plate or the protrusion at the time of engaging. CONSTITUTION:If a ferromagnetic protrusion 3a of a tool B to be attracted is so mounted as to be engaged with a small diameter part 4a' side of a deformation hole 4a of an attracting tool A, the overhang collar 3b of the protrusion 3a is introduced to a gap between a peripheral edge of an engaging plate 4 of the tool A at the small diameter part 4a' side and the inner periphery of an inserting gap 5, and not removed. Since the protrusion 3a is not brought into contact with a ferromagnetic plate 2 or a ferromagnetic protrusion 2a, the plate 3 is brought into close contact with the attracting surface of the tool A, and lines of magnetic force are concentrated over a gap (s) between the protrusion 3a and the protrusion 2a or the plate 2, thereby increasing an attracting effect.

Abstract: PURPOSE:A high-temperature gas mixture containing pyromellitic dianhydride is introduced into a column with walls wetted with an organic medium to effect heat exchange between the gas mixture and the organic medium, then introduced into a column scrubber whereby pyromellitic dianhydride is readily and continuously collected with an organic medium. CONSTITUTION:An organic medium is introduced from nozzle 1 to the top of wall-wetted column 2, while a high-temperature gas mixture containing pyromellitic dianhydride is introduced from line 3. The gas mixture contacts with the films of the organic medium on the walls, while it passed through the column 2 to effect heat exchange to crystallize out a part of the pyromellitic dianhydride. The pyromellitic dianhydride crystallizing out is collected in the film of the organic medium. The resultant slurry or solution is exhausted out of the column bottom through line 4 to the solid-liquid separator 5. The gas mixture, after heat exchange, is brought into contact with the organic medium jetted from the shower nozzle 8 countercurrently, while it goes up through the column whereby pyromellitic dianhydride is collected.
