摘要： PURPOSE:To prevent the drop of a steam permeation quantity due to clogging of a membrane surface, by monitoring the differential pressure of the membrane of a membrane demister provided to the passage of steam and the dosage rate of the membrane surface, and washing the surface of the membrane demister accordingly. CONSTITUTION:The steam generated within a dryer 1 is led to a mist separator 2 and brought into contact with a washing solution supplied from a membrane demister 3, and large mists are removed. The steam to rise through the separator 2 goes out from the upside and is led to the membrane 3. The steam permeates pores of the membrane 3 and on that occasion the mist is catched. By this, a decontamination factor is improved. The differential pressure between the inlet and outlet of the membrane 3 is measured by a differential manometer 7, the dosage rate of impurities adhering to the membrane 3 surface is monitored by a dose meter 8, and the surface is washed with a washing nozzle 9 provided in front of the membrane 3 surface, by supplying the condensed water from a condenser 4, when either value of those becomes a fixed value or more. By this, impurities adhering to the membrane 3 surface are removed, and the drop of a steam permeation quantity and the deterioration of the membrane 3 due to the radioactive material can be prevented.

摘要： PROBLEM TO BE SOLVED: To improve the positioning accuracy and reliability of a semiconductor substrate. SOLUTION: This device has a press contact structure such that a semiconductor substrate 13 stacked by electrode layers 11a and 11b and stress absorbing materials 12a and 12b in the surface region except for the periphery is sandwiched by post electrodes 14a and 14b. In two ring members 17a and 17b, projecting parts 17A and 17B are formed along the inner circumference. When the ring members 17a and 17b are fit, end faces 17A1 and 17B2 of the projecting parts 17A and 17B directly sandwich the semiconductor substrate 13, thereby positioning the semiconductor substrate 13 for the post electrode 14a. Since inner circumferential faces 17A2 and 17B2 of the projecting parts 17A and 17B restrict the movement of the outer circumferential faces of the stress absorbing members 12a and 12b and the movement of the outer circumferential faces of the electrode layers 11a and 11b, the situation such that a load is applied on a protective member covering the edges of the semiconductor substrate 13 is prevented.

摘要： PURPOSE: In the aerobic cultivation of a microorganism, the oxygen dissolved in the culture mixture is properly controlled through three stage operations, namely the control of the rotation of the stirrer in the first stage, of the oxygen partial pressure of the aeration gas in the second and of the aeration rate in the third.
CONSTITUTION: A germ seed is charged into the cultivation tank 1 and the substrate is fed from the tank 2 through pump 8 to the tank 1. At this time, signals from the D0 sensor 9, the oxygen partial pressure meter 5 and the aeration rate meter 6 are processed in the control computer 4 and another signal is sent to the oxygen separator 3, the stirrer 2 or the pressure controller 11 in accordance with the control programs to control the stirrer rotation, the oxygen partial pressure in the aeration gas or the aeration rate. Thus, when D0 in the culture mixture is lowered, the rotation of the stirrer is increased as the first stage, when the D0 comes to the upper limit of set value, the oxygen partial pressure in the aeration gas is raised as the second stage, and further, when coming to the next upper limit, the aeration rate is increased as the third stage.
