Abstract: It is an object of the present invention to provide an electronic equipment of a high design property having an optical disc drive mounted thereon and an inexpensive and high-quality opening and closing mechanism for a tray door. The electronic equipment includes a front panel on a front surface of the equipment, and a link 25 rotatably engaged with a tray door 22. The tray door is provided with cams 22b engaged with cam pins 20b provided on the front panel to control the locus of the movement of the tray door. The discharging movement of the tray causes the link to be pushed and rotated by the tray, whereby the tray door is slid to below the tray with its upper design surface left turned upwards in the form of the movement controlled by the rotation of the link and the locus of the cams, and in this manner, the tray door is opened.

Abstract: An electronic apparatus, comprising: an optical disk drive, having an eject button for opening/closing a disk tray, and a controller means 1 for controlling and instructing the eject button; a tray open/close button for opening/closing the disk tray; a controller means 2 for controlling opening/closing of the disk tray, and a means for operating the eject button of the optical disk drive, which is disposed within a housing of the electronic apparatus, from an outside thereof.

Abstract: A reinforcing composition for mineral structures which comprises as reactive ingredients one or more radical-polymerizable or copolymerizable monomer and a bisulfite ion-supplying substance. The use of the reinforcing composition facilitates reinforcement of natural or artificial mineral structures and products.

Abstract: Dry process for the production of inorganic granular substances coated with plastics, characterized in that a radical-polymerizable vinylic monomer carried on the surface of an inorganic granular substance is brought in a gaseous phase into contact with gaseous sulfur dioxide to effect polymerization of the monomer. The resulting plastic-coated inorganic substances are useful in various fields of industry, for example, as fillers, construction materials, molding materials, electrode materials, delayed-action fertilizers, etc.

Abstract: A transition metal compound in powdered form or a mixture of a transition metal compound and other inorganic compounds in powdered form can be effectively coated with a polymer by contacting such powder with a vinyl monomer in the presence of hydrogen sulfite ions (HSO.sub.3 .sup.-).

Abstract: Particulate solids are coated with a polymer by bringing a particulate solid selected from glass particles, abrasive particles and sand particles into contact with a vinyl monomer in the presence of a polymerization intiator consisting essentially of bisulfite ions.

Abstract: A hardenable molding composition comprising hydratable gypsum, a vinyl monomer, a source of hydrogen sulfite ions and water is disclosed. With this molding composition a hardened product can be obtained having high strength due to the combined effect of the hydraulic reaction of the gypsum and the polymerization reaction of the vinyl monomer.

Abstract: Metal powder is suspended in an aqueous medium containing a radical-polymerizable monomer and polymerization is conducted in the presence of an acidic sulfite ion to produce a plastic coated metal powder which is effectively used for forming conductive plastics, molded articles for sintering, pressed powder magnetic cores and the like.

Abstract: A method of manufacturing reinforced resin moldings, wherein a fiber-reinforced plastic, obtained by the polymerization, in the presence of an inorganic fibrous substance selected from the group consisting of glass fiber, slag wool and asbestos, of a vinyl monomer, within an aqueous medium in the presence of sulfur dioxide, said fiber-reinforced plastic being composed of 5 - 50 wt.% of resin and 95 - 50 wt.% of inorganic substance and coated with a polymer, is subjected to compression molding.
