Abstract: Polymeric resin matrix phase (thermoplastic, thermosetting or biomass) is reinforced with fiber filament or fine particles to enhance the mechanical properties (particularly, bending strength and bending stiffness), impact strength while keeping its original transparency. Plastic brackets (either previously reinforced as mentioned above or un-reinforced) can be surface-treated by plasma coating with thin film or simply ultra violet radiation to enhance the surface mechanical properties as well as anti-frictional force against the archwire's movement while again maintaining its transparency. Accordingly, the present invention can provide orthodontic brackets made of plastics with high mechanical strengths and clearness, so that aesthetic appearance is improved.

Abstract: A mirror for examining a confined area such as an intraoral cavity including posterior teeth, distal and/or lingual sides of teeth, is provided. The mirror includes a lit fog-free and contaminant-free mirror. Basically, the mirror includes a holding stem component and a mirror component. In the holding stem portion, a battery, motor, and on/off switch and rotation speed controlling device are present. In the mirror portion, a mirror is adhered to a rotatable disk, which rotates inside a circular concave housing and is driven by a shaft which is connected to a shaft in the holding stem component via a connecting mechanism. The circular concave housing has an outer circular surrounding collar which includes a plurality of sub-collars of irregular shapes. When the mirror on the rotatable disk is rotating, air turbulence is generated to spin off any dust, debris, contaminant, and moisture from the mirror surface. The mirror also includes an illuminating light to which electric power is supplied from an installed battery. Hence, the mirror surface is bright enough even when posterior teeth, distal and lingual sides of the teeth are observed and is moisture-free and dust-free.

Abstract: A method for bonding bodies made of metallic material is described herein, which method is characterized in that one ends of metallic bodies are butted against each other with a light mechanical load applied to the butted portion, and under such a loaded condition the proximity of said butted portion is subjected to a temperature cycle passing over a transformation point of said materials, whereby said metallic bodies may be pressure bonded while super-plastic phenomena are generated in said butted portion of said metallic bodies. In one preferred embodiment, the above-referred loaded condition can be realized without specifically and purposely applying a mechanical force to the bodies to be bonded, but instead one ends of the materials are butted against each other with the main portion thereof maintained in a substantially restrained state, so that the necessary mechanical load to the butted portion may be generated as compression stress based on thermal stress when said temperature cycle is applied to said bodies to be bonded.
