Induced electric power 10 is generated in the billet 1 by a magnetic field 8 and moving force of an arrow 9' is applied to the molten steel 2 of the billet by the power 10. The moving speed V of the molten steel is expressed by V=K0(f0-f) where the power source frequency of an electromagnetic stirrer 4 is designated as f0, the frequency of the induced electric power of the billet 1 as f and the constant K0. Since K0 and f0 are known, the moving speed V of the molten steel is detected by detecting (f) by a contactor 5 on the opposite side of the billet.

Title: Plated resin article
Inventor: MAEDA TETSUO
IPC: C08F279/00
Filed: 1984-02-09
Abstract: PURPOSE:To obtain a transparent plated ABS resin article, by a method wherein an ABS resin molded article comprising a specified amount of a diene rubber having a weight average particle diameter not larger than a specified value is subjected to wet-type plating. CONSTITUTION:An ABS resin comprising 10-24wt% of a diene rubber having a weight average paticle diameter of not larger than 150mum (particularly, not larger than 100mum) is molded. The molded ABS resin article is subjected to wet-type plating by a known method to obtain a transparent plated ABS resin article. If the weight average particle diameter of the rubber is larger than 150mum, the transparency of the plated ABS resin article becomes poor. If the rubber content is less than 10wt%, the adhesion of a plated film becomes poor. On the other hand, if the rubber content is more than 24wt%, fluidity is unfavorably lowered.

Abstract: PURPOSE:To inspect a space between a light-emitting element and a transparent glass plate easily by clogging the upper surface of the opening section of a cap covering the light-emitting element by the glass plate through low melting- point glass. CONSTITUTION:A glass plate 8 is joined with the upper surface of a cap 7 through low melting-point glass 10. The lower surface of the glass plate 8 can be viewed with eyes from an upper section because the low melting-point glass 10 is opaque. Consequently, when the focus is adjusted by a microscope, a space (l) between the upper end of a laser diode chip 4 and the lower surface of the glass plate 8 can be grasped accurately because the lower surface of the glass plate 8 and the upper end of the chip 4 as a light-emitting element can each be observed. Even a space (L) up to the upper surface of the glass plate 8 can also be made clear because the thickness of the glass plate 8 can be made known by a design drawing, etc.

Abstract: PURPOSE:To reduce the interference between adjacent recording tracks, by splitting each recording track into a plurality longitudinally and providing a means which inserts recording tracks split longitudinally to split intervals, in producing parallel magnetic recording tracks to a magnetic substance medium. CONSTITUTION:A head has two parted magnetic gaps like 5, 5'. The length (l) of the interval between the gaps 5 and 5' is taken almost the same as a normal gap length L.

The gaps 5 and 5' move to 6, 7... and 6', 7'... respectively as shown in figure. When recording is made with the 1st head having the gaps 5 and 5' and reproduction is made with the 2nd head having the gaps 15 and 15', the vicinity near the response 0 is mitigated and the interference of the adjacent recording tracks like recording tracks 1 and 2 can be reduced through the azimuth system.

Abstract: PURPOSE: To provide the titled film which has excellent adhesive properties to adherends (e.g. electrical wires) and retains heat resistance which polyimide resins originally possess, by monoaxially stretching a polyimide film formed from a specified polyamic acid.  
     CONSTITUTION: Biphenyltetracarboxylic acid dianhydride (BPDA) (e.g. 3,4,3',4'- BPDA) is reacted with an arom. diamine (e.g. 4,4'-diaminodiphenyl ether) in an org. polar solvent (e.g. N,N-dimethylformamide) to obtain a polyamic acid soln. having an intrinsic viscosity of 0.5 or above. Then this soln. is casted on a substrate. Part of the solvent is evaporated to form a film which is then heated to 200W 500°C. During this stage, at least 50wt% polyamic acid is converted to the corresponding polyimide (it is preferred that the volatile matter content of the film is not  more than 10wt%). Then the resulting film is monoaxially stretched 1.05W5 times  as long to obtain the desired heat-shrinkable polyimide film.
