Title: Method for detecting abnormality in ionic activity measurement
Inventor: SAITO YOSHIO
IPC: G01N27/26
Filed: 1985-10-15
Abstract: PURPOSE:To easily detect the abnormality of a potential measuring system by measuring the potential difference between a pair of ion selective electrodes when a reference liquid and liquid to be inspected are supplied to an ion activity measuring system and further measuring the potential difference when a resistor of a prescribed value is connected in parallel to a potentiometer. CONSTITUTION:The potential difference E between a pair of ion selective electrodes is measured by a potentiometric system V when the reference liquid and the liquid to be inspected are supplied to the ion activity measuring system A by turning a switch SW off. The potential difference ER when the resistor Re having the value of 0.1-10 times the value of the internal resistance of the ion selective electrode pair is connected in parallel to the potentiometer V by turning the switch SW on is measured. Discrimination is made that the internal impedance Ri of the measuring system A is abnormal if such potential difference is out of a permissible range as compared to the standard relation between E and ER preliminarily determined from the standard value of Ri.

Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to obtain compatibility with various types of power saving without any auxiliary power supply, by applying a direct-current supply voltage from a commercial power line to a primary-side PWM control circuit and the like when a switching stabilized power supply is started. SOLUTION: A circuit comprising diodes D1-D7 and capacitors C1-C3 is clamped from a commercial power supply 1 with a voltage required for applications 3, so that negative voltage will not be produced during a period of negative half-wave rectification. A clamp circuit is constituted of such diodes and capacitors. That is, a voltage requested by applications, such as PWM control circuit, is supplied from the commercial power supply only at the time of switch-on during a period of positive half-wave. When, after starting, stabilization is obtained, power supply is switched to that from a switching transistor T1, and power supply is stopped. When a switch 2 is turned on at this time, an alternating current is supplied from the commercial power supply 1, and half-wave voltage is applied to point A.  As a result, the capacitance of the capacitor C2 for direct-current power supply dedicated to starting is made sufficiently smaller than the capacitance of C3.
