Title: Gas chromatograph
Inventor: OTA HAJIME
IPC: G01N30/86
Filed: 1991-10-21
Abstract: PURPOSE:To measure each component of sample gas accurately in gas chromatography. CONSTITUTION:The value of a gain offset voltage VG1 is measured before the arrival of a component 1 of sample gas, which arrives at first. The peak voltage of the arrived component 1 is measured. The value of the offset voltage VG1 is subtracted from the peak voltage, and the true peak voltage is obtained. When gain switching is performed for the measurement of the peak voltage of the following component 2, a gain offset voltage VG2 of the component 2 is computed based on the already-measured gain offset voltage VG1 and the switched gain value. The computed offset voltage VG2 is subtracted from the peak voltage of the component 2, and the true peak voltage is obtained. As a result, the gain offset voltages VG1 and VG2 caused by the gain switching are perfectly removed, and all components of the sample gas are accurately measured.

CONSTITUTION:The constituting components of the photograhpic processing agent contg. the constituting components for preparing the acidic hardening fixer contg. at least thiosulfate and water-soluble aluminum salt contain at least one kind of the acid components which have 0.1mol/liter ion intensity and <=5.0 logarithmic value pka of the inverse number of an acid dissociation constant at 25 deg.C and are solid at ordinary temp. and at least one kind of such acid components are solid and are so formed as the large particles as to have 3.00X10<-3> to 13.0X10<-3>m<2>/g specific surface area by a BET method. Since these acid components are large particles, the solubility at the time of preparing the fixer is gentle. The rapid degrease in the pH arising partially in the liquid is suppressed in consequence of the gradually dissolution. The sulfiding of the fixer which is thiosulfate is thus prevented. The acid components are an org. acid and/or hardener and further, contain the respective constituting components in a solid state.

Filed: 1995-10-12
Abstract: PROBLEM TO BE SOLVED: To provide a method for repairing by obscuring the traces of removing and repairing the defects on the surface or near the surface of artificial marble having no gel coating layers on its surface. SOLUTION: The surface of the artificial marble 1 having no gel coating layers is cut shallow or polished to remove the defects 2 near the surface. In succession, a coating material 4 contg. a silicone compd., such as silicone varnish or denatured silicone varnish, or contg. a fluorine silane compd. is applied on the parts 3 where the defects are removed. The marble is thereafter rested until the coating material 4 cures or is heated to accelerated the curing in order to shorten the curing time. The surface is made flush by polishing at need after curing of the coating material. The coating material 4 contg. the silicone compd. or the fluorine silane compd. is slight in difference in the gloss from the ambient artificial marble 1 and, therefore, the traces of the repair are obscure. In addition, the surface hardness is relatively large and the hot water resistance is sufficient.

Abstract: PURPOSE:To provide a rotary type coating device where excess coating liquid is prevented from being splashed about to the outside to contaminate the surroundings. CONSTITUTION:A trap part 20b is installed in a spacer 20. When a turntable 6 is turned and given centrifugal force equal to or greater than the constant one, excess coating liquid from a base plate 2 is stored in a trap part 20b.
