Title: Evaluation of wettability of molton metal by utilizing microgravity environment
Inventor: NAGAI HIDEAKI
IPC: G01N13/00
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To carry out quantitative evaluation of wettability without requiring measurement of the contact angle and the surface tensile force by measuring the shapes of a single molton metal kept still on a substrate under a normal gravity and a micro gravity and measuring the wettability from the alteration of the shapes of the molton metal under the normal gravity and the micro gravity. SOLUTION: A molton metal has an approximately elliptical shape under a normal gravity and has an approximately spherical shape under a micro gravity. In this case, the contact point of the molton metal and the substrate moves and the interface surface area of the molton metal and the substrate is decreased. The work lost in the decrement of the interface surface area is adhesion work and corresponds to the potential energy lost of the molton metal when the gravity is changed from the normal gravity to the micro gravity. As long as the liquid shapes of the molton metal put on the substrate can precisely be recorded, any types of image recording apparatuses such as a camera and a video camera may be employed.

Title: Magnetic recording medium and its production
Inventor: KITO MAKOTO
IPC: G11B5/72
Filed: 1985-03-27
Abstract: PURPOSE:To prolong the life of the title magnetic recording medium by vapor- depositing perfluoroalkylcarboxylic acid on the surface of a magnetic recording medium obtained by providing a ferromagnetic body vapor-deposited thin film on a nonmagnetic substrate. CONSTITUTION:A lubricant of an org. substance forming only a monomolecular layer is vapor-deposited on the surface of a magnetic recording medium obtained by providing a ferromagnetic body vapordeposited film on a nonmagnetic substrate. Perfluoroalkylcarboxylic acid such as perfluoroacetic acid and perfluoropropionic acid is used as the org. substance forming only a monomolecular layer. When the substances are vapor-deposited, the carboxylic acid is deposited on the side of the thin film magnetic recording medium and firmly attached to the side and the surface is formed with fluorocarbon. Since the surface layer of the fluorocarbon has small surface energy and is immediately vaporized and scattered, a monomolecular layer can be easily formed. Consequently, the medium is not stuck to a head during sliding, the characteristic is not deteriorated and the life of the magnetic recording medium is prolonged.

Abstract: PURPOSE:To sufficiently suppress the pressure variation on the downstream side of a self-operated pressure regulator by operating a self-operated pressure regulator automatically to the direction of valve opening or valve closing forcibly only for a specified time by the operation of an electric drive means which receives an instruction from a timing setting device when a flow rate regulating valve is operated rapidly and with a large change in opening. CONSTITUTION:When the load that is detected increases much, the degree of opening of a pressure regulator 2 is increased forcibly and in an appropriate width by an electromagnet 10 a little faster than the increase in the degree of opening of a flow rate control valve 5, and then the degree of opening of the flow rate control valve 5 is increased rapidly and in a great deal to obtain a large calorific value which matches a large load in a large size combustion device 3. And, when a value of load that is detected decreases much rapidly, the degree of opening of the pressure regulating device 2 is reduced forcibly and in an appropriate width by the electromagnet 10 a little faster than the reduction of the degree of opening of the flow rate regulating valve 5, and then the degree of opening of the flow rate regulating valve 5 is reduced rapidly and in a large width in order to obtain a small calorific value which matches the small load of the large size combustion device 3.
