摘要： A sheet made from a foamed polystyrene resin which is heat-shrinkable in one axial direction and has a heat-insulatingness is prepared. A printing process is applied to this sheet to produce a label. A container made from a thermo-plastic resin is covered with said cylindrical label and is put in a furnace in order to heat-shrink the label to be fitted on the container.The container with the label manufactured in accordance with the present invention has a superior heat-insulatingness, and thus can maintain the temperature of water contained therein for a longer time. Also, when it is used in a electronic-range, a temperature of an outer wall surface of the container can be prevented from increasing, and thus the container can be held by a bare hand even immediately after cooking.

摘要： An optical pick-up apparatus for writing and/or reading information on and/or from an optical record medium including a light source, an objective lens projecting a light beam emitted by the light source onto the optical record medium, a holding member holding the objective lens movably in a focusing direction to perform a focusing control, a carriage to which the holding member is secured, a supporting mechanism for supporting the carriage movably in a tracking direction to effect a tracking control as well as an access control, and a driving member moving a movable member including the objective lens, holding member and carriage in the tracking direction. The supporting mechanism includes guide rails extending in the tracking direction and slide bearings formed in the carriage and coupled with the slide bearings. A coefficient of static friction of the movable member is set to a value not larger than 0.25.

摘要： An optical system driving apparatus including a holder 2 supporting an objective lens 1, resilient supporting members 29a, 29b for supporting the holder movably in a focusing direction Z perpendicular to a record medium, and focusing coils 4a, 4b secured to the holder 2 by means of viscoelastic members 3a and 3b. The focusing coils 4a, 4b and a viscoelastic members 3a, 3b serve as a dynamic damper so that undesired resonance can be effectively suppressed without narrowing a control frequency range.

摘要： Shafts are fixed to a base and extend in a direction parallel to a center axis of a through hole of the base. Two yoke arrangements are installed to the shafts. A lens holder frame holds a lens, which has an optical axis parallel to the central axis of the through hole of the base. The lens holder frame is axially placed in a space between the two yoke arrangements and is swingably supported by a plurality of wire springs, which are fixed to the base. Drive coils are fixed to the lens holder frame and generate a drive force to move the lens holder frame.
