Filed: 1987-12-18
Abstract: PURPOSE:To reduce the electric current consumed by a data I/O which uses a battery as a main power source so as to extend the usable time of the battery by providing a data latching circuit, control circuit, etc., and making the time accessing a RAM shorter. CONSTITUTION:An address signal AD from a CPU 4 is supplied to a control circuit 3 together with clock signals CLK. The circuit 3 outputs the signal AD which accesses a RAM 1 and a chip select signal CS and transfers the data read-out from the RAM 1 to a data latching circuit 2 composed of a high- speed C-MOSIC so as to make the access to the RAM 1 completed. Therefore, the RAM 1 which consumes a relatively large quantity of electric current is cut off and the data of the circuit 2 are secured until the RAM 1 rewrites the data. Thereafter, the data of the circuit 2 are read by a CPU 4 from the circuit 2 at the fall of data reading timing T3. By making the CPU 4 accessing time of the RAM 1 shorter and using the circuit 2 which consumes a less quantity of electric current in such way, the life of the battery can be extended.

Abstract: PURPOSE:To detect a high frequency magnetic field with high sensitivity by arranging a magnetic field detecting element, whose at least one or more faces in the axial direction are made of a superconducting body, in a constricted part in a cylinder made of a superconducting body. CONSTITUTION:A material in the superconductive state shows the Meissner effect to push the magnetic field to the outside of the material.

Meanwhile, end faces of the element 2 consisting of a cavity resonator are formed with two disk-shaped superconducting bodies 21 and 22, and the side face part of an interval (d) between them is formed with a metal in the normal conductive state. When the magnetic field H is applied, the normal conductive state and the superconductive state are brought about together in the element 2, and the high frequency magnetic field is detected with high sensitivity by the Q value and the change of the resonance frequency value.

Title: Automatic cooking control method of electronic cooking range
Inventor: KI TAE OU
IPC: H05B6/68
Filed: 1988-12-22
Abstract: PURPOSE: To conduct automatic cooking accurately while enhancing reliability by shortening the period for detecting inflow air temperature and lengthening the period for comparing the detected temperature thereby setting a temperature increment quickly. CONSTITUTION: Temperature Ui of air flowing into a heating chamber 4 in the initial state is detected at a constant period and when a current temperature Ui is equal to a temperature stored in a memory, temperature fluctuations ΔU, ΔV are determined for inflow air and outflow air thus determining a temperature increment compensation value δ. The value δ is subtracted from a preset temperature increment ΔT to set a compensated temperature increment ΔT' (initial operation process). Heating operation is then conducted until the temperature Vj of outflow air from the heating chamber 4 increases by ΔT' (first stage heating process). Subsequently, heating operation is conducted for a time equal to the first stage heating time multiplied by a constant α dependent on the kind of food (second stage heating process).
