Title: Pollution detecting method
Inventor: IWATSUKI MINORU
IPC: H01B17/00
Filed: 1993-01-12
Abstract: PURPOSE:To measure stain with high accuracy without being influenced by a part of an electrode by taking a measured value of an electrode when the increasing ratio of a leakage current between electrodes or of the electrode monitored at all times becomes not larger than a set ratio, and averaging the measured values for each electrode. CONSTITUTION:Switching circuits 3, 4 in the lateral and longitudinal directions connected to each of many electrodes 2 on an insulating plate 1 are sequentially switched, and the selected electrode 2 is connected to a measuring resistance 8. When a current running in the resistance 8 is measured, a leakage current of the selected electrode 2 flows in the circuit and an electromotive force proportional to the leakage current is generated in the resistance 8. A voltage value at both ends of the resistance 8 is input by an operational device 10. In other words, the device 10 monitors the leakage current between electrodes at all times, performing an operation between measured values YA1 and YA2, of the leakage current t1 and t2, seconds later from the star of dampening. When the increasing ratio (YA2-YA1)/YA2 becomes not larger than a set ratio, it is so judged as the generation of saturation, and the measured value at that time is read. Accordingly, it is possible to detect pollution with high accuracy if the whole saturation values are taken and averaged at a completing time point irrespective of the part of every electrode.

Filed: 1974-12-25
Abstract: An electronic timepiece powered during use by a cell comprises an oscillating circuit for generating a high frequency output signal and a multi-stage divider circuit for receiving the high frequency output signal and dividing it at successive stages to lower frequency output signals and providing at its last stage standard pulses suitable as a time standard. A first gate circuit receives the divided signals and gates therethrough higher frequency pulses than that of the standard pulses. A control pulse generating circuit generates a given number of control pulses having a predetermined pulse width in successive predetermined periods, and a second gate circuit receives at its input both the higher frequency pulses and the control pulses and gates therethrough a number of higher frequency pulses corresponding in number to the predetermined period within the duration of the predetermined pulse width. A timing device responds to pulses applied thereto for indicating time, and a voltage detecting circuit detects the cell output voltage and provides one signal when the cell voltage is above a predetermined voltage level and another signal when the cell voltage drops below this level. A third gate circuit connected to the voltage detecting circuit responds to the one signal and gates the standard pulses to the timing device and responds to the other signal and gates the higher frequency pulses to the timing device. The timing device indicates the time in the normal manner in response to the standard pulses and in a periodic abnormal manner in response to the higher frequency pulses thereby signifying to the user that the cell is near exhaustion and needs replacement.

IPC: H01L21/76
Filed: 1984-01-13
Abstract: PURPOSE:To improve the withstand radiation property of a semiconductor integrated circuit by a method wherein element isolation regions are made with an excess silicon- containing insulating substance. CONSTITUTION:An etching is selectively performed on the surface of a substrate 101 using masking materials 103 for etching provided on the semiconductor substrate 101 respectively as a mask. P type impurities 105 are ion-implanted in the bottom parts of etched grooves 104 using the masking materials 103 respectively as a mask for performing an ion-implantation and channel stopper regions 106 are formed. After the masking materials 103 were removed, a silicon oxide film 107 is made to grow on the surface of the substrate 101. Insulating substance films 108 containing excess silicons having a large number of covalent bondings between insular silicon particles or silicon atoms are formed in only the etched grooves 104. According to this constitution, even though the insulating element isolation regions were irradiated with an ionizing radiation, a positive charge electrification scarcely generates in the substance films 108, because electron-hole pairs immediately recouple by excess silicons and annihilate. As a result, the withstand radiation property of the semiconductor integrated circuit is improved.
