Abstract: PURPOSE:To produce the titled high-purity beta-type silicon carbide powder in a short time by electrical heating a mixture of metallic silicon powder and carbon powder to excite a chemical chain reaction. CONSTITUTION:Metallic silicon powder and carbon powder are mixed in 0.5/1.5 ratio of C/Si, and the mixed powder is electrically heated or induction-heated in a vacuum or an inert gas atmosphere (Ar, He, etc., are used at ordinary pressure - 200atm). The power at this time is preferably controlled to about 100-2,000W, and beta-type SiC powder of high purity (

Abstract: PURPOSE:To obtain the peep projector of simple constitution suited for large volume producion by mounting or dismounting a film case containing film to or from a film case mounter and viewing the images of the film through the peep window provided to this mounter. CONSTITUTION:A film case 1 is mounted or dismounted to or from the fitting port 2 provided on the other side of a film case mounter 4 which is provided at one side with a peep window 3 mounted with a lens. An endless film 12 wound to a film containing disc 10 provided within the film case 1 is set to the feed drum 8 and film intermittent moving device 11 in the case 1 and the film 12 is moved by the rotation of the film feed drum 8, whereby the change of images may be enjoyed through the peep window 3. Another images may be enjoyed by replacing the film case 1 with other one of different images. In this way, the peel projector of simple construction suited for volume production may be obtained.
