Title: Cooker
Inventor: ITO YUICHI
IPC: F24C7/02
Filed: 1988-12-29
Abstract: PURPOSE:To prevent a turning table form rotating at a high speed due to a failure of a photo-interrupter, in microwave oven cooking, by a method wherein one motor is used both of a turning table in microwave heating and for a kneading bar in dough kneading. CONSTITUTION:When cooking starts, it is judged whether it is microwave heating or dough kneading, and when it is dough kneading, a motor 17 is kept in operation at a full rotation speed until the cooking finishes. When it is microwave heating, the motor 17 is operated at a large output for a t1 seconds at the first step. When t1 seconds has passed, a rotation speed higher than Xrpm is input to a microcomputer 26. If the rotation speed is less than Xrpm, it is such a case that a photo-interrupter 35 is in a trouble. In this state, it is judged that the rotation speed is less than 6rpm after t3 seconds has passed at the third step, and the output of the motor 17 is increased by one step successively, and finally causing the motor 17 to operate at a maximum output to rotate a turning table 4 at a high speed. To avoid such a dangerous state, when the rotation speed is less than Xrpm after t1 has passed at the first step, the motor 17 is stopped to finish cooking, and the trouble of the motor is informed to a user.

Abstract: PURPOSE:To elevate the orientation property of a superconductive phase by filling a superconductive oxide in spiral grooves around a fire-resistant insulating tube, and shifting a fused part, which is formed by heating this oxide partially from one end of the groove to the other end continuously. CONSTITUTION:Oxide powder 13 in superconductive composition is filled in the groove 12 of a fire-resistant insulating tube 11 where a spiral groove is formed at the periphery. This powder is retained in the groove 12 by the flocculation of the powder 13 itself by being pushed by proper force. Next, a resistance heater 14 is arranged near the groove at one end of the insulating tube 11 so as to partially put the oxide powder 13 near the heater 14 in fused or half fused conditions. Next, the insulating tube 11 is rotated with the center axis as the axis, and simultaneously the heater 14 is shifted in the axial direction of the insulating tube 11 at the speed in accordance with the groove pitch so as to shift the fused or half fused part along the groove 12. Hereby, oxide powder 13 in the groove 12 solidifies after being fused or half fused in order.

Title: Decoloration of colored waste water
Inventor: MORI TATSUMA
IPC: C02F1/00
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To obtain an sufficient decoloration effect over a long period by penetrating colored waste water and more preferably, the waste water of livestock farming of a brow color subjected to a purification treatment into andosol which is volcanic soil. SOLUTION: When the chromatic waste water is penetrated into the andosol 5, the soil particles adsorb the coloration components contained in the chromatic waste water and decolor the chromatic waste water. When the penetration rate of the chromatic waste water is limited to <=60ml per 1g andosol at this time, the decoloration rate of the waste water attains >=60% and the decoloration effect sufficient for practicable use is exhibited. The reason why the andosol 5 exhibits the adsorption effect in such a manner is estimated to line in that the andosol contains much allophane and that the adsorption by an anion exchanger is actively effected. The andosol 5 varies in adsorption capability by the areas where the andosol is distributed. The andosol 5 which is distributed particularly in the Sannin district of Japan and contains much humus exhibits the excellent adsorption capability.
