摘要： Flame-retardant epoxy resin compositions comprising a polyepoxide, an acid anhydride curing agent, an imidazole curing accelerator, aluminum trihydrate powder and red phosphorus powder or red phosphorus powder coated by a thermo-setting resin have a lower viscosity and therefore show a longer pot life and better workability on casting as compared with prior art resin compositions. Also, a fly-back transformer coil produced by casting of said flame-retardant epoxy resin compositions is flame-retardant. Even if it burns slightly, no toxic gas is produced. Therefore, the coil has advantages in that a magnet wire is not corroded and voids are difficult to be formed and thereby partial discharge is difficult to occur, resulting in a long life and a stable output voltage.

摘要： A rear projection apparatus having a projector containing a light source and a liquid crystal cell, a mirror for reflecting a light from the projector, and a screen for projecting the light reflected by the mirror. The screen is being composed of an optical film having an optical element capable of forming a spatial distribution of light transmittance, a light shield layer and a light diffusion layer. The light shield layer is positioned between the optical element and the light diffusion layer and is composed of a compound which changes light transmittance depending on irradiation of an energy beam. The light transmittance passing the light shield layer is modulated spatially depending on a dose of the energy beam.

摘要： For removing re-deposited particulates produced during an etching process of a magnetic head slider and forming a minute chamfered portion, a polishing process is carried out by using polishing cloth such as non-woven polyester fabric after having formed rails of non-linear shape on a floating surface by the etching process. Thus, the re-deposited particulates produced during the etching process are removed, whereby the reliability of the floating characteristic of magnetic head is improved.
