摘要： PROBLEM TO BE SOLVED: To solve the problem of a recorder using a reversible thermal recording medium, e.g. a rewritable paper, that the medium is readily electrified because the surface and back surface of the rewritable papers mounted on a sheet feed tray are touching each other, the rewritable papers stick together due to static electricity thereon and are not separated at a separating section to cause misfeed of sheet or the like. SOLUTION: The sheet feed tray 60 is formed of a conductive material (de-electrifying means), e.g. aluminum, at at least a part touching the rewritable paper 3 in order to prevent sheet a feed error due to static electricity on the rewritable paper 3.

摘要： PROBLEM TO BE SOLVED: To provide a liquid raw material for CVD which can dissolve even a material which causes many troubles in a conventional tetrahydrofuran (THF) solvent without troubles such as the occurrence of precipitations, which can be transferred through piping without clogging, and which can be applied to a solution vaporization system without the problem of vaporization efficiency. SOLUTION: A liquid raw material 9 for CVD is prepared by mixing one or more kinds of organometallic compounds into a solvent containing one or more kinds of polar solvents, and dissolving the compounds to a saturated state or below. The polar solvent contains at least one or more kinds selected from the derivatives of tetrahydrofuran (THF, C 4 H 8 O), and does not contain the tetrahydrofuran itself. Thus, the material which causes many troubles in the conventional THF solvent can be dissolved without troubles such as the occurrence of precipitations or the like and can also be transferred through piping 16 without clogging.
