Title:
METHOD AND DEVICE FOR MOVING LIQUID AND MEASURING DEVICE UTILIZING THESE METHOD AND DEVICE
Document Type and Number:
Japanese Patent JPH0610900
Kind Code:
A
Abstract:

PURPOSE: To form a flow of no pulsation in a circulating path and to provide no dead space, so that a fine amount of liquid can be allowed to accurately flow, by giving energy to liquid exposed from an outlet part of the circulating path so as to continuously vaporize the liquid.

CONSTITUTION: A liquid reservoir part 2 for accumulating liquid is connected to one side of a fine circulating path 1, to form the other side to serve as an outlet part 3 of an opening. Relating to a pressure by a level of liquid in the liquid reservoir part 2, internal resistance of the circulating path 1 and surface tension of a liquid surface exposed to the outside in the outlet part 3 are balanced, to place a flow in a stationary condition. Now when vaporizing energy is given to the liquid exposed in the outside in the outlet part 3, the liquid in the outlet part 3 is vaporized to become vaporized matter 4 and released. Then by a vaporized amount, the liquid is supplied by a capillary phenomenon to flow in the outlet part 3 through the circulating path 1. Now when the vaporizing energy is continuously given to continue vaporization, a flow of no pulsation can be formed in the circulating path 1.
