Abstract: PURPOSE:To enable the exact observation of welding phenomena without fluctuation in actual welding by providing a notched part on the side opposite from a welding surface on one side face of a base material and generating an arc along the contact surface between the quartz glass fitted in the notch and the side face of the notch. CONSTITUTION:A notched part 11 is provided on one side face of a base material 1 on the side opposite to the welding surface 10 of the material 1 except a flange-shaped part 12 which is allowed to remain on the face 10 side. The notched part 11 extends along the one side face of the base material. The one end edge of quartz glass 2 is tightly fitted in the notched part 11. The glass 2 is then disposed with its observation surface exposed to the outside without intervening in the welding surface of the base material 1. A welding wire 4 is positioned along the contact surface between the glass 2 and the side face of the notched part 11, and an arc 3 is generated along the contact surface. On the other hand, a light source 6 for extinguishing the arc is disposed so as to face to the welding position. The welding is observed with a camera 5 while it is progressed in an arrow direction.

Title: Continuous casting method of molten metal
Inventor: NAKAI KAZUYOSHI
IPC: B22D11/11
Filed: 1984-06-26
Abstract: PURPOSE:To prevent the sticking of slag to the wall surface of a tundish and to permit the easy reuse of the tundish by sucking away the molten slag in the tundish by a vacuum suction type slag remover when the pouring of a molten metal into the tundish is completed. CONSTITUTION:A header 1 of the vacuum suction type slag remover sucks away the slag 4 on the surface of the molten metal 3 through an aperture part 7 provided to a cap 6 of the tundish 2. The slag removal is started at such a timing when the removal of the slag 4 is completed upon completion of the pouring of the molten metal from a ladle 5. The time required for the reuse of the tundish after the casting is thus considerably reduced.

Title: Reading and writing separation type thin film magnetic head
Inventor: TANABE MASANORI
IPC: G11B5/31
Filed: 1986-06-09
Abstract: PURPOSE:To eliminate the need to position both heads and improve the writing and reading characteristics, and to improve the SN ratio and perform high- density recording by making a cut in the surface of a magnetic head facing a recording medium and separating the head into a writing and a reading head. CONSTITUTION:A lower magnetic film 3, a magnetic gap member 4, a conductor, and an upper magnetic film 6 are formed successively on a nonmagnetic substrate, and the cut is made in the tip part of the head along the orthogonal direction of the surface opposite the recording medium. The width TW of the writing head which has an upper magnetic film 51 is made larger than the width TR of the reading head to reduce off-track noises. A material which has low magnetic permeability is used for films 31 and 51 to lower the readout sensitivity of the head, thereby preventing the operation at the time of writing from affecting the reading head. A part 10 which has high magnetic permeability is provided to the film 5 of the reading head. Therefore, both heads need not be positioned breadthwise, the writing and reading characteristics are improved, and the SN ratio is increased, so that high-density recording is performed.

Title: Rubber composition
Inventor: IWASA TADANOBU
IPC: C08L33/02
Filed: 1982-07-30
Abstract: PURPOSE:A rubber composition, obtained by incorporating a special furnace carbon black with a rubber, and vulcanizing the resultant mixture, and having improved processability, e.g. extrusion characteristics, etc. and remarkably improved hardness and tensile stress. CONSTITUTION:A rubber composition obtained by incorporating furnace carbon black having 40-80mg/g iodine adsorption and >=140ml/100g dibutyl phthalate oil absorption with a rubber material, selected from natural rubber or synthetic rubber, and vulcanizing the resultant mixture. If the iodine absorption is below the lower limit value, sufficient hardness and stress are not obtained. If the iodine adsorption exceeds the upper limit value, the dispersibility is reduced, and the physical properties are widely varied. If the dibutyl phthalate oil adsorption is below the above-mentioned value, the dispersibility is reduced in case the iodine adsorption is large. Sufficient pnysical properties are not obtained in case the iodine absorption is small. EFFECT:The amount of the carbon black to be incorporated can be reduced for obtaining the equal physical properties. Thus, the weight of the rubber composition can be reduced.
