Title: Correcting device for sensor output with hysteresis
Inventor: KUBOTA TOMOKI
IPC: G01D3/02
Filed: 1986-02-22
Abstract: PURPOSE:To obtain a high-accuracy sensor by using a material of low quality by storing hysteresis basic characteristic data of the sensor, generating reduction data from the data, and correcting the sensor output with the basic or reduction data. CONSTITUTION:A storage and arithmetic device 4 is stored previously with data on basic hysteresis characteristics of the sensor 1. A correction is mad with the basic data unless torque being measured is inverted in polarity in increasing or decreasing. If the polarity is inverted at some point of the characteristic data, the device 4 regards the return point between the increase and decrease in torque as a peak point and reduces the data about an origin as a center. The output of the sensor 1 is corrected on the bases of the reduced data and real torque is calculated and outputted. Thus, the hysteresis of the sensor 1 is easily corrected, so the high accuracy is obtained by utilizing the inexpensive material of low quality for the sensor.

Title: Electronically controlled cooker
Inventor: USAGAWA TATSUMI
IPC: F24C7/02
Filed: 1988-02-22
Abstract: PURPOSE:To stop the heating control from being started when a heating command has been given independent of the unstable condition of the sensor output prior to passage of a set time after turning on an AC power supply by providing a circuit designated to stop the execution of the heating. CONSTITUTION:When a command for heating specifying the condition for the heating is keyed in, despite a sign 'WAIT' on the display with a signal current circulating through steps S3-S5 prior to passage of a set time T after turning on an AC power supply, the step S4 acts thereupon, causing a step S7 to be executed. Since, however, the passage of the set time T has not yet been completed at this stage, a step S8 remains unexecuted, the signal current being returned to the step S3 and made to circulate through the steps S3-S5 without starting the heating control. Thus, it is stopped for the heating control to be started according to data on the detected humidity by a sensor under unstable condition; with the heating control started upon stabilization of the data on the detected humidity by the sensor, this system of cooking does not involve faulty cooking of foods to an undesirable state.
