Filed: 1990-04-27
Abstract: PURPOSE:To measure the flow rate with good accuracy and stability even in an area of low Reynolds number by applying vibrations of a high frequency to a fluid flowing in a fluid device from outside of the liquid device with use of a vibrator such as a piezoelectric element. CONSTITUTION:A turbulent flow device 11 is provided which generates a turbulent flow by applying vibrations of a high frequency to a fluid running in a fluid logic element F of a fluid logic element flowmeter as a liquid device with use of a vibrator 11a, e.g., a piezoelectric element from outside of the flowmeter. In other words, the turbulent flow device 11 is attached to an upper lid 13 at the side downstream of an inlet 1 to a space 12. Since vibrations of a high frequency generated by force through excitation of the piezoelectric element 11a are added to the fluid from a main nozzle 2, the uniformity of the fluid velocity in the main nozzle 2 is improved, and the viscosity of the fluid is restricted. Therefore, the flow becomes a sufficiently developed turbulence even in an area of low Reynolds number. In this manner, it becomes possible to measure the flow rate with good accuracy and stability over an area of low Reynolds number.

IPC: G03F7/095
Filed: 1991-04-17
Abstract: PURPOSE:To get a high-resolution resist pattern which has a rectangular shape without decrease of a resist film. CONSTITUTION:A volatile material 1, which has shading property to an exposure X ray and volatilizes when the X ray is applied, is overlaid on a resist 2, and then the pattern is exposed. In the section abundant in the quantity of exposure, the volatile material 1 volatilizes immediately, and the resist is exposed, so the drop of quantity of applied light is small. On the other hand, in the section poor in the quantity of exposure, that volatile material 1 does not readily volatilize and the quantity of light which has reached the resist decreases sharply by the shading property. Accordingly, the X rays which have turned into the shading part, can be reduced enough, and it follows that the resolution improves.
