Title: Penetration structure for high temperature tubing of reactor containment vessel made of concrete
Inventor: NAGATA TETSUYA
IPC: G21C13/036
Filed: 1988-11-11
Abstract: PURPOSE:To control the temperature increase by heat transferred on a housing at an allowable value or less by setting the minimum value at which such a radiation that the local temperature of the concrete housing shows the allowable value or less is made possible and making the outside length of a containment vessel of a sleeve the length equal to or longer than the minimum value. CONSTITUTION:In regard to the outside projected length L of a containment vessel the outer diameter D1 of a sleeve 4 or the diameter D1 of high temperature tubing 2 is used as parameters and the minimum value at which such the radiation that the local temperature at the contact portion with the sleeve 4 of a concrete housing 1A is made the allowable value or less is made possible is set and the outside length L of the containment vessel of the sleeve 4 is made equal to or longer than the minimum value. The outside projected length of the containment vessel of the sleeve 4 is 1,200mm or more in the case where the outer diameter of the sleeve 4 is 800A or less, the outside projected length is 1,400mm or more in the case where the outer diameter is 1100A, and the outside projected length is equal to or more than the value which is a linear interpolation of the said two values in the case where the outer diameter is from 800A to 1100A. As a result, the contact portion with the sleeve 4 on the reactor containment vessel concrete housing 1A can be controlled at 90 deg.C or less of the allowable value of the temperature increase thereof.

Title: Analog input system
Inventor: EGAMI NORITAKA
IPC: G01R27/02
Filed: 1991-10-07
Abstract: PURPOSE:To provide an analog input system on which the temperature change hardly has an influence. CONSTITUTION:A measured value is corrected by the output A/D conversion value obtained in the case of inputting voltages at one middle points of bridge circuits 1a to 1n to both input terminals of differential analog amplifiers 3a to 3n, or respective middle point voltages of bridge circuits 1a to 1n are inputted to input terminals of analog amplifiers 3a to 3n in order and the measured value is obtained based on the differences of output A/D conversion values. Thus, an influence of the temperature change is effectively excluded to obtain the analog input system of high precision.

Filed: 1991-10-31
Abstract: PURPOSE:To prevent destruction of a gate insulation film by providing a transistor, whose channel length is short, between the gate and the signal output terminal of an output transistor and thereby preventing a high voltage from generating between the gate and the source or the drain. CONSTITUTION:The channel length is set as mum, transistors(TRs) Q1, Q2 as 1.5, TRs Q3, Q4 as 1.0 which is sufficiently short, a control signal phi1, phi2 is inputted to the gates of TRs Q1, Q2, and an output signal is obtained for a signal output terminal Dout. TRs Q3, Q4 are not operated under a normal state, but an electrostatic discharge voltage in negative polarities is applied to the terminal Dout, the gate potential is dropped to the same potential as the terminal Dout. Therefore, a high voltage is not applied between the gate and the source of TR Q1 or between the gate and the drain of TR Q2; and since TRs Q3, Q4 are sufficiently short in the channel length, the charge is discharged before the gate is destroyed. Thus, the destruction of the gate insulation film is prevented.

IPC: H01L21/302
Filed: 1990-10-23
Abstract: PURPOSE:To prevent etching defects after reactive ion etching(RIE) and improve the precision of the formation pattern by shifting the focus during exposure. CONSTITUTION:After coating the surface of the SiO2 process substrate 2 with a g-line positive photoresist and baking on a hot plate, a specially designed reticule and g-line stepper with a 0.54 N.A. (lens opening) are used and the pattern is transferred after shifting the focus 0.5mum from the best focus point in the direction of shortening the distance between the process substrate 2 and the lens. After that, when the post exposure bake is completed, the development process is performed and a resist pattern l is obtained. By shifting the focus during exposure in this way, the more minute the pattern is, the more possible it is to taper resist patterns and minimize the microloading effect during RIE processing. As a result, the occurrence of etching defects can be prevented and the precision of the formation pattern can be increased.
