Patent JP-S62294954-A (JP)
Title: Apparatus for determining component in liquid
Inventor: OKAMOTO TOYOKATSU
IPC: G01N27/416
Filed: 1986-06-14
Abstract: PURPOSE:To achieve a higher working efficiency, by a method wherein a voltage to be applied between two electrodes is provided once raised higher than a measuring voltage when a power source is closed and after a fixed time, it is set for the measuring voltage to reduce the time until current output of a sensor section is made ready to measure after the closing of a power source. CONSTITUTION:When a power source is closed, a switch SW at a bias switching circuit section 2 is kept open by a signal from an arithmetic processing section 6 and a voltage V1 higher than a measuring voltage is applied between two electrodes of a sensor section 3. With the application of the voltage V1, a large jump current flows through the sensor section 3 and, then, the current lessens gradually to regain a stable condition. Then, the processing section 6 for which a specified time is set previously generates a signal after a specified time elapses from the closing of the power source to close the switch SW of the bias switching section circuit 2. Then, a measuring voltage V2 is applied between the two electrodes of the sensor section 3. As an electric charge is stored across the sensor section with the voltage V1, with a discharge, a reverse current flows temporarily but soon, a positive current flows to regain a stable condition.

CONSTITUTION:A temperature T of a holding body 38 is detected by a thermistor 40 as the thermosensitive element and is sent to a comparator 44 and is compared with a set temperature T0, and an output corresponding to the difference (T-T0) between them is sent to a temperature controller 46, and the power supply to a Peltier element 42 is so controlled that the temperature of the holding body 38 is equalized to the set temperature T0. Consequently, the temperature of the holding body 38 is controlled to a value near the set temperature T0, and the temperature of a semiconductor laser 10 is controlled to a value near the temperature T0 indirectly. If the characteristic curve is changed with time, the set temperature set to the comparator 44 is changed manually by a set temperature changing means 48.

Title: Measuring method for film thickness
Inventor: KISHIDA HARUO
IPC: G01N23/06
Filed: 1978-11-13
Abstract: PURPOSE: To enable the measurement under a wide variety of conditions such as types of material, state of material, and film thickness, by using mono-color X-rays in spectrum and selecting the energy near the X-ray absorption end of measured substance.  
     CONSTITUTION: The absorption edge effect is used by using the emitted X-ray having the energy width of comparatively narrow region as measured media. For example, the characteristic X-rays from an element (including the both of emitted X-rays and fluorescent X-rays) have two or more peaks of energy depending on the exciting conditions. The K series rays and the L series rays are generated with sufficient intensity and the lower energy rays, the L series rays in this case, are selected near the absorption edge of measured substance. The ratio of intensity between the K and L series rays of the characteristic X-rays generated is constant independently of the amount of excitation if the excited energy is constant. Since the ratio is remarkably changed when the X-rays transmit through the film, the thickness can be obtained from the ratio of intensity of transmission by experimentally or theoretically calibrating the relation with the thickness.
