    • This invention is intended to improve the heat resistance of PET bottles from a material aspect. A technical problem of this invention is to find a polyester resin which is suitable for heat and pressure resistant plastic bottles and which does not eat into productivity and is available at a low cost. The object of this invention is to provide a heat and pressure resistant plastic bottle that can be manufactured at a low cost and has pressure resistance at a high temperature and high impact strength. The means of fulfilling this object is a polyester resin comprising a major part of ethylene terephthalate units and containing at least one of minor copolymerizable components selected from a group consisting of isophthalic acid, cyclohexane dimethanol, and diethylene glycol, wherein three minor copolymerizable components have total content less than 3 mol. %.

    • An illumination device includes a control knob having a display portion, a tubular case combined with a back side of the control knob, a light guide plate attached to seal an upper opening of the tubular case, and LEDs disposed at a lower opening of the tubular case. Light emitted from the LEDs is applied to the display portion through the light guide plate. A plurality of retaining projections and a plurality of push-up projections are provided on an inner surface of the tubular case adjacent to the upper opening. An upper surface of an outer edge of the light guide plate is retained by lower ends of the retaining projections, and a lower surface of the outer edge is pushed up by upper ends of the push-up projections so that the light guide plate is held inside the tubular case while being bent upwardly.
