CONSTITUTION:When the cooking materials are put into a cooker and an AC power supply 3 is applied, the voltage Vd according to the temperature T is delivered from the point of connection between a thermistor 15 and a resistance 16. This voltage is converted into a detected temperature signal S1 through an A-D converter 17 to be supplied to a data converting part 18. At the beginning of application of the power supply 3, the detected temperature T is lower than 115 deg.C and a data converting part 18 is preset at the preset 20 after receiving the output of ''16'' as the digital information value D. At the same time, a driving signal S3 is delivered to turn on a thyristor 2. Thus the electric conduction is applied to a heater 1 to start heating, and a counter 20 counts the count signals S0. The ''16'' is preset again when the counter 20 counts 16 signals and then set at 0, and the heater 1 generates heat with the rated output of <=115 deg.C and then with the corresponding rated output at other levels of temperature.

Title: Inorganic plate and its production
Inventor: KUBO MASAAKI
IPC: C04B38/08
Filed: 1994-07-19
Abstract: PURPOSE:To reduce the weight of a cement-based inorganic plate formed through a curing and hardening treatment and containing lightweight aggregates without reduction of mechanical strength by making up this plate from three layers composed of surface layers and an interlayer and making the percentages of dimensional change of both the surface layers almost equal to each other and different from that of the interlayer during the course of curing and hardening. CONSTITUTION:This method for production of inorganic plate can improve mechanical strength since a prestress is generated between the front and back surface layers and the interlayer by dimensional change during the course of curing and hardening process. In this method, occurrence of a warp is scarce since both the front and back surface layers of the inorganic plate exhibit an almost equal dimensional change during the course of curing and hardening process. In addition, during the course of curing and hardening, one of the surface layers, and the interlayer is shrunk whereas the other is swollen. As its result, a high prestress is generated by a synergetic effect of the shrinkage and the swelling and it contributes to improvement of mechanical strength. Specifically, if vermiculite and 5 to 20wt.% pearlite are contained respectively in the surface layers and the interlayer, the interlayer us swollen without fail.
