Title: Frequency adjusting method for sensor piezoelectric resonator
Inventor: KOYAIZU YASUO
IPC: H03H9/13
Filed: 1994-03-26
Abstract: PURPOSE:To enable frequency adjustment by evaporating a frequency adjusting metal onto the electrode of a piezoelectric resonator, directly or through a chemical reaction material. CONSTITUTION:A sensor electrode 2 is formed by evaporating Cr, as the base material of Au, at the facing position on both sides of a piezoelectric diaphragm 1, and then Au on the Cr, and further ZnO7 as a chemical reaction material on it. In this state, frequency is set higher than the desired one. The frequency is adjusted by evaporating an Ag6 in a not so wide area around the center of an electrode 2. That is where the frequency is easiest to change. The Ag6 may be evaporated on the ZnO7, the peripheral part of the electrode 2, instead of the central part of it. That is, the central part is for sensor action, and the peripheral part is used for frequency adjustment.

Filed: 1987-04-01
Abstract: PURPOSE:To obtain a compound useful as a surfactant for liquid detergents, shampoos, medicines and cosmetics, by sulfating or phosphorylating a polyoxyethylene alkyl ether by a conventional method, subjecting the resultant product to thin film evaporation and neutralizing the resultant substance. CONSTITUTION:A polyoxyethylene alkyl ether is sulfated or phosphorylated by a conventional method to provide a reaction product, which is then subjected to thin film evaporation at <=50 deg.C under reduced pressure, preferably at 20-40 deg.C under <=100mmHg pressure in an inert gas stream, such as nitrogen or air, to remove 1,4-dioxane. The resultant product is subsequently neutralized with a neutralizing agent, such as caustic soda, to afford the aimed substance. Since water is not required in evaporating and removing the 1,4-dioxane, foaming will not occur at all. Furthermore, since formation of the 1,4-dioxane as a by-product by thermal decomposition is suppressed and evaporation efficiency of the contained 1,4-dioxane is good, the aimed substance is obtained at a low treating cost.
