Abstract: A liquid jet recording method using a recording head provided with a liquid jet part comprising an orifice through which the liquid is jetted to form a flying liquid droplet and a heat action section in communication with said orifice in which section the thermal energy for jetting the liquid acts on said liquid, and an electro-thermal transducer serving as means for generating the thermal energy, said method characterized in that said thermal energy is made to act on the liquid filling said heat action section so as to jet from said orifice such amount of liquid sufficient enough to include unnecessary bubbles generated in said liquid jet part and a liquid droplet is formed by said jetted liquid whereby said unnecessary bubbles are eliminated from said liquid jet part while repeating said liquid droplet formation to perform recording with said droplets. Further, said method is characterized by applying to said electro-thermal transducer a driving signal having a voltage value in the range of 1.02 to 1.

Abstract: The present invention provides a closure mechanism applied to a cartridge inserting opening in a floppy disk drive or the like and including a lid member rotatably supported on a panel having an opening through which a cartridge or the like can be inserted into the floppy disk drive, the lid member biased toward its closed position under the action of a biasing spring which is rigidly mounted at one end on the panel with the opposite free end being engaged by the lid member under a biasing pressure such that the biasing force on the lid member can be maintained substantially constant by slidably moving the free end of the biasing spring on the surface of the lid member when the lid member is being opened.
