Title: Liquid level control method
Inventor: SUZUKI KIYOSHI
IPC: G05D9/04
Filed: 1978-06-20
Abstract: PURPOSE: To secure an instantaneous and high-accuracy control for the liquid level by moving up and down the liquid level via the tangible substance and without varying the temperature characteristics of the controlled liquid.  
     CONSTITUTION: The lower end of stainless steel closed hollow column 2 is inserted into liquid H and supported with piston bar 21 of pen cylinder 20. Float 3 is floated to be opposed to action part 5 of switch 4 fixed at the prescribed position. Air source 6 is connected to device 11 (comprising filter 8, adjustment valve 9 and pressure gauge 10) via manual valve 7 and then connected to the upper part of cylinder 20 via electromagnetic valve 12 operated with switch 4 and flow amount adjustment needle valve 14. Flow amount adjustment needle valve 15 is closed constantly when in use. In this constitution, the exhaust liquid amount is varied for the tangible substance pushed into part of the controlled liquid to control the liquid level, and thus no change occurs to the temperature of the controlled liquid. As a result, an instantaneous and high-accuracy control becomes possible for the liquid level via the up and down movement of the tangible substance. The tangible substance features a hollow substance with reduced heat capacity and thus gives no effect to the temperature control.

Abstract: PURPOSE:To reduce the voltage dependency of a capacitor by constituting the lower electrode of the capacitor in impurity concentration higher than source and drain regions. CONSTITUTION:A field SiO2 film 2 is formed to one main surface of a P type Si substrate 1, a gate oxide film 3 is formed, and the gate electrode 5 of a MISFET by a poly Si film and the lower electrode 6 of the capacitor are formed to the whole surface. Ion beams 7 of an N type impurify are irradiated to the whole surface. Consequently, the N<+> type source region 8 and drain region 9 are formed on both sides in a self-alignment manner as using the electrode 5 as a mask while the resistance of the film 6 is reduced. A section on a MISFET section is coated selectively with a photo-resist, the ion beams of the N type impurity are irradiated while using the photoresist as a mask, and the quantity of the impurity introduced into the film 6 is increased. As a result, the film 6 is changed into N<++> type, and displays sufficiently low resistance value as the lower electrode of the capacitor. A SiO2 film 12 as a dielectric film is grown on the exposed surface of the film 6. Accordingly, a depletion layer is made difficult to extend in the film 6 on operation as the capacitor.
