Patent JP-H0370984-A (JP)
Title: High-frequency induction smelting furnace
Inventor: IWANO KUNIZO
IPC: F27B3/08
Filed: 1989-08-10
Abstract: PURPOSE:To prevent reaction between smelting metal by a method wherein specified sol-type or slurry-type refractory is applied on the inner wall of a second crucible in a first crucible and, thereafter, is calcined to form a coated mold. CONSTITUTION:In order to form a coated mold 7 in a second crucible 6, arranged detachably in the inner periphery of a first crucible 5, refractory, having a melting temperature higher than a material metal thrown into the second crucible 6 and an oxidizing degree in the melting temperature larger than the same of the material metal, is mixed with adhering water to produce slurry-type or sol-type refractory while the refractory is applied uniformly on the inner wall of the crucible 6. In this case, the crucible 6, manufactured by slip casting method, is porous with the porosity of 20% or more and, therefore, the adhering water will never flow along the inner wall but is absorbed quickly into the crucible 6 whereby the refractory may be adhered to the inner wall of the crucible 6 surely. According to this method, oxidizing and/or reducing reactions between the smelted metal and the crucible 6 may be precluded while the coated mold 7 will never be molten whereby smelting with a high purity may be effected.

Title: Tile shape measurement method and device therefor
Inventor: FUNAISHI YASUYUKI
IPC: E04D1/04
Filed: 1993-07-30
Abstract: PURPOSE:To measure a tile shape with relative ease and yet with accuracy by rolling a probe having a roller continuously in the state of contact with the upper or reverse side of a tile, and finding data about the center position of the roller at every measurement point. CONSTITUTION:A tile W is horizontally placed on the support members 36 and 38 of a turntable 22, and the positioning lever 68 of a portal section 50 is coupled to the predetermined positioning hole. Furthermore, a probe 128 fitted to the lower end of the measurement board 114 of a main measurement section 78 is kept in contact with the upper surface of the tile W and a measurement switch is operated to roll the roller of the probe 128 from a tile batten to a hipped section via a valley section. When the board 114 and a lifting body traverse the surface of the tile W due to the change of the vertical contact position of the roller, the vertical position thereof is read at a constant interval. In this case, when a tangential line with a circle expressed with the roller is drawn, the crossing point of a segment orthogonal with the tangential line and the center of the roller becomes a measurement point. Position data is arithmetically processed at each measurement point, and saved as measurement data. Also, a straight line is drawn between each measurement point to display the surface of the tile W approximately.

CONSTITUTION:When an abnormality is generated in a cooling device and the contact 2 of a protecting device B is opened, the excitation of an auxiliary relay 6 is released, the contact 6a is opened and a compressor 10 is stopped. In this case, the conduction of the primary side of a photocoupler 5, inserted in series to a self-holding circuit, is interrupted and, therefore, the transistor of the secondary side of the photocoupler is turned OFF whereby the voltage of an input 2 is changed from Lo level into Hi level with a time constant determined by the values of a resistor and a capacitor. The contact 1 of the protecting device A is closed in this case and the primary side of the photocoupler 4 is conducted consequently whereby the voltage of an input 1 is left in Hi level as it is. A microcomputer in a control device 9 detects this condition whereby the operation of the protecting device B may be detected.

Abstract: PURPOSE:To prevent deterioration in the life of an ink ribbon and a film ribbon by making arc the cross-section of a printing end of printing wire. CONSTITUTION:Printing wire 8 is held by a tip guide 6 attached to a nose 1, wire guides 7 and back guides 14, and also is guided so that 1, zigzags in two longitudinal rows at its tip. The tip of the printing wire is circular without the edge of the wire end.
