Title: Sensor circuit
Inventor: OOSHIMA KOUSEI
IPC: G05B11/36
Filed: 1984-05-15
Abstract: PURPOSE:To enhance the capacity of heat-cooking under all humidity environments, by enhancing sensitivity under low and high humidity conditions by forming a discharge circuit using a bidirectional non-linear element. CONSTITUTION:When voltage VIN is equal to a peak value VSS, voltages at both terminals of a bidirectional non-linear elements ZD1 become high even if the charge current of a condenser C1 is slight and voltage VOUT becomes also large. Because voltages at both terminals of the element ZD1 are constant even if the charge current becomes high and voltage VOUT is proportional to the reciprocal of sensor resistance RH, linearity is obtained and the sensitivity of a sensor circuit in a low humidity state is improved. Because the element ZD1 is bidirectional, the charged voltage of the capacitor C1 is discharged through the element ZD1. Then, constant at the time of discharging becomes almost equal to that at the time of charging and discharge is rapidly performed based on an extremely small value. Therefore, the charge applied to the capacitor C1, during the time when voltage VIN is equal to the peak value VSS, is discharged during the zero-volt period of voltage VIN. As a result, the sensor resistance RH (relative humidity) and the voltage VOUT show a linear characteristic and the sensor circuit shows good sensitivity even in low and high humidity regions.

Filed: 1985-05-10
Abstract: PURPOSE:To perform dynamic evaluation with high efficiency and high accuracy by using a secondary operator to add the rounding error between two data obtained by a main operator and the rounding error between the error data obtained by the secondary operator. CONSTITUTION:For the block diagram of an arithmetic circuit for addition/ subtraction, a main addition/subtraction device 5 and a secondary addition/ subtraction device 6 have the 64-bit width and the 16-bit width respectively. Under such conditions, the device 6 is used to carry out the operation between error data DELTAu and DELTAv read out to lines 21 and 22 in parallel with the main operation of the device 5. Then the rounding error DELTA(u+ or -v) obtained through a line 23 is added to the value (DELTAu+ or -DELTAv) obtained through a line 24 by the device 6 as soon as the main operation is through. The result of this addition is stored in an error register DELTAw. Here only the final DELTAw+(DELTAu+DELTAv) is carried out after the main operation. Thus just one-to-several scale suffices with the device 6 together with the extremely short time of operation compared with the device 5.

Title: Simultaneous measuring method for composition and density of thin film sample by epma
Inventor: NAKAGAWA YUKA
IPC: G01N23/225
Filed: 1990-04-13
Abstract: PURPOSE:To easily measure the element concentration and density of a sample even when both are unknown by finding respective element concentration values and density values with which an intensity ratio by the measurement of elements becomes equal to a calculated intensity ratio. CONSTITUTION:The respective component element concentration values and density values of a thin film of the sample are assumed from the X-ray intensity ratio of characteristic X rays radiated from the thin film of the sample excited with an electron beam accelerated with a proper acceleration voltage or a single body standard sample of component elements. Then computer simulation based upon the assumed thin film component element density values is carried out to calculate the X-ray intensity ratio and the concentration values and density values which are so assumed to equal the X-ray intensity ratio obtained by the measurement are corrected. The corrected values are used to repeat the same calculation and then the thin film and density can be determined in the manner of successive approximation. Consequently, even when the respective element concentration values and density values are both unknown, a qualitative analysis using X rays is taken to enable the measurement.
