By removing this moisture absorbed in the hygroscopic agent, the reproduction of the hygroscopic agent is executed. When the reproducing stage of the hygroscopic agent in the dry unit 13 approaches to its end, the shutter 12 gradually moves to the position to be closed, and when the shutter 12 outside the store reaches the position shown by the continuous line, the positive temp. coefficient thermistor 14 becomes off state, and the reproducing stage of the hygroscopic agent in the dry unit 13 is finished.

Abstract: PURPOSE: To evaluate an error included in a terminal current value according to an error distribution of current density, etc., by determining a closed area containing the interface between a terminal electrode whose error is to be found and an element, and finding the terminal current error. CONSTITUTION: Element characteristics such as the current density distribution, etc., in the element are calculated. Then the error distribution of the current density and an error distribution of the generation rate of unit positive charges found from the generation recoupling rate of carriers are found. Then the closed area 2 containing the interface between the electrode 1 of the terminal whose error is to be found and the element is determined and in the closed area 2, the error in terminal current value is estimated from the quantity obtained by integrating the error of the generation rate of the unit positive charges and the quantity based upon the error of outward current density that is perpendicular to the surface 3 of the closed area at the part excluding the electrode interface of the closed area surface 3.  Therefore, a user of a simulator can distinctively judge whether or not an analysis is taken with sufficient precision. Even when a grating is a little rough, a precise value can be obtained by correcting the terminal current value.

Abstract: PURPOSE:To abate a force fight as securing accuracy by detecting a signal of a forward circuit, making it feedback to a command signal, while integrating a deviation between a displacement signal and this command signal, and inputting it into the forward circuit. CONSTITUTION:A signal of a servoamplifier 21 (forward circuit) varying according to external force being added to an actuator is amplified by a gain alphad and fed back to a command signal. Then, a deviation between a current feed back value to the command signal and a piston position feedback value is integrated by an integrating circuit 33 with a transfer function, say, Ka/S, and a deviation between this integral output and the piston position feedback value by a demodulator 16 is inputted into a servoamplifier 21. With this constitution, since a steady-state deviation by external force is adjustable to an optional value, a force fight is abatable as securing accuracy.

Filed: 1988-07-11
Abstract: PURPOSE:To form a semiconductor layer simultaneously upon formation of an epitaxial semiconductor layer of a semiconductor layer forming substrate and to reduce an impurity automatic doping by disposing the substrate held at a low temperature oppositely to a semiconductor substrate. CONSTITUTION:A semiconductor layer forming substrate 4 of a temperature lower than that of a semiconductor substrate 2 to be formed with an epitaxial semiconductor layer 3 is disposed oppositely to the substrate 2. Thus, the layer 3 is epitaxially grown on the substrate 2, and the substrate 4 is also covered with a semiconductor layer 31. In this case, the temperature of the substrate 4 is set to a temperature lower than that of the substrate 2 formed with the layer 3 to be formed. An impurity evaporated from the substrate 2 is efficiently doped in the layer 31 on the substrate formed at the low temperature in this manner. An automatic doping to the layer 3 epitaxially grown on the substrate 2 to be formed is effectively avoided.
