Title: Automatic welding machine
Inventor: TAKI MASAKAZU
IPC: B23K9/127
Filed: 1984-03-26
Abstract: PURPOSE:To raise a profiling accuracy of a weld line by detecting a distance between a magnetic sensor and an object to be welded, so that the distance becomes a prescribed one. CONSTITUTION:When welding is executed, an object 5 to be welded is deformed due to a thermal distortion. As a result, a variation is generated in a distance between the object 5 to be welded and magnetic sensors 6a, 6b, by which a low frequency magnetic field received by a receiving coil is varied. The variation of this low frequency magnetic field is converted to an electric signal by a low frequency magnetic field receiver, and used as a control signal of a distance control device 12. A driving motor of the distance control device 12 rotates so that a driving mechanism moves in the upper direction, if the distance between the magnetic sensors 6a, 6b and the object 5 to be welded is smaller than an initial set value, and on the contrary, rotates so that the driving mechanism moves in the lower direction, if said distance is larger than the initial set value. Accordingly, a constant interval is always held even in case when the object 5 to be welded is varied, and the distance between said object and the magnetic sensors 6a, 6b is varied.

Abstract: PURPOSE:To improve remarkably the utility factor of raw material, while the flatness of a product is kept and the breakage or crack in the product does not occur by grinding with a copy buff the outer peripheral surface of the ceramic molding having been formed under isotropic pressure. CONSTITUTION:In the finishing process of the ceramic molding having been formed under isotropic pressure, the high smoothness of an outer peripheral surface is obtained by, buffing the outer peripheral surface of the molding.

Title: Cooker
Inventor: MATSUMOTO TOSHINARI
IPC: F24C7/08
Filed: 1986-03-17
Abstract: PURPOSE:To prevent the boiling-over and scorching of the content of a cooker from occurring by a method wherein a sensing part, which is arranged at the central part of a cooking hotplate and contacts with the bottom of a cookpot, is provided so as to reduce the electric power when the temperature at the bottom of the cookpot reaches a specified temperature in order to heat the cookpot from that time on at another specified temperature, which is lower than the equilibrium temperature at boiling of the content. CONSTITUTION:A sensor part 12, in the interior of which a sensor 13 is arranged, is provided at the center of a cooking hotplate 11. When a power switch 17 is turned ON, the cooking hotplate 11 is brought into energized state so as to be raised in temperature in order to heat a cookpot 15. When the temperature of the sensor 13 reaches 95 deg.C, a control circuit 16 reduces the power consumption of the cooking hotplate 11. As a result, both the temperature of the sensor and the inner temperature of the cookpot 15 decrease in their rising speeds so as to bring them to their equilibrium states at boiling. Then, when the temperature of the sensor 13 comes also the equilibrium state, the control circuit keeps a temperature lower than that of the equilibrium temperature of the sensor by 2 deg.C so as to hold the mild boiling state to the end of cooking.
