    摘要: It is an object of the invention to provide a video projector which can be driven by a battery and can be reduced in both size and weight. A packing case for a video projector is composed of a cabinet, which is divided into two upper and lower parts, and a cover disposed behind the cabinet. The cover is disposed removably with respect to the cabinet. By opening the cover situated behind the projector light source, a lamp forming the projector light source can be replaced easily. Also, the cover includes on the back surface thereof a battery mounting portion for mounting a battery used to drive the projector, so that the battery can be mounted to the outer back surface of the cover.

    摘要: A firing underlying board having a long use life free from thermal expansion and which does not cause twisting of ribs, deformation of an end face, color change or cracking in a honeycomb structural body fired on the underlying board. The firing underlying board is composed mainly of 55-85 wt % of cordierite and 15-45 wt % of mullite. The firing underlying board is used to fire green ceramic honeycomb structural bodies placed thereon.
