Title: Color erasable with water
Inventor: MATSUI YOSHI
IPC: C09D5/06
Filed: 1989-06-21
Abstract: PURPOSE:To prepare a color which turns bright white when water is added to it and which is removable with water by mixing cobalt thiocyanate, a white pigment, and a water-sol. binder. CONSTITUTION:A color which can be erased with water is prepd. by mixing cobalt thiocyanate, a white pigment, and a water-sol. binder. Cobalt thiocyanate is prepd. from Ca(SCN)2 or NH4SCN as a thiocyanate salt and CoSO4, CoCO3 or Co(NO3)2 as a cobalt oxide. TiO2, Al2O3, or CaCO3 is used as the white pigment; and sodium cellulose glycolate, as the water-sol. binder. Capable of sensitively reacting with water to change its color, the resulting color is useful for detecting a defect such as a water-leaking section, and the moisture content or dryness of a chemical contg. the resulting color can be confirmed by the change in color of the chemical.

A so-called in-situ vapor etching method wherein a gas in which a group III source has been bypassed in a substrate- placed growth region and which is provided with the etching action of HCl or the like is used as the vapor etching operation. Since impurities are contained in the HCl gas, a reaction tube is purged by means of a carrier gas after the vapor etching operation, and the impurities which are left inside the reaction tube are removed and treated. Thereby, a high-purity epitaxial film can be grown on the clean surface of the substrate.

Filed: 1979-12-04
Abstract: PURPOSE:To detect incomplete combustion of fuel through detection of change in the flame structure. CONSTITUTION:A detector unit 1 consisting of a sensor 1a and a sensor holder 1b in placed above a secondary-air controlling plate 3 which couples a plurality of burners to each other, in the manner that it is not held in contact with flame 4, and an air passage 1c is formed in the detector unit 1 in the manner that it extends perpendicularly to the flame flow. When the secondary air is supplied sufficiently, uniform flame is formed as shown at 4 in the drawing. However, when the amount of the secondary air is not sufficient and the amount of O2 at a flame hole portion where the secondary air controlling plate 3 is located is reduced resultantly, negative pressure is developed locally above the plate 3 by the upward flow of the secondary air, so that the flame as shown at 4' in the drawing is formed. In this state, the density of O2 is lowered and CO is produced. Here, if such a flame structure 4' is detected by the sensor 1a, it is enabled to detect incomplete combustion of fuel and to stop supply of fuel gas.
