Title: Investment composition for dental casting
Inventor: MORIWAKI YUTAKA
IPC: A61K6/00
Filed: 1983-03-18
Abstract: PURPOSE:The titled composition that contains, as a refractory material, crystalline aluminum tertiary phosphate, thus having excellent thermal expansion properties and giving molds with fine-texture surfaces. CONSTITUTION:The titled composition contains more than 5wt% of a powder of aluminum tertiary phosphate of less than 200mum particle sizes. When metallic moldings for dental purposes such as metallic crowns or inlays are formed by forming a molding with an investment and casting the molten metal of dental alloy into the mold, then solidifying it by cooling, the metal alloy causes volume contraction during the cooling, and it is required that the thermal contraction must be compensated by utilizing the thermal expansion of the investment on curing and heating. Aluminum tertiary phoshate causes no large change in thermal expansion all over the heating temperature zone and forms no crackings on heating, because it has a large thermal expansion coefficient. As the aluminum tertiary phosphate, berlinite or tridymite which is crystalline and free from crystal water is preferable.

Title: Image forming device
Inventor: ITO CHIHARU
IPC: H04N1/23
Filed: 1988-02-29
Abstract: PURPOSE:To miniaturize the device and to lower its cost by setting the number of faces of a rotatory polygon mirror to measures in which one is excluded of the total of scanning lines, and also setting the number of light beam generating means to measures except one, which is obtained by dividing the number of faces of the rotatory polygon mirror by the total of scanning lines, and by searching measures of the quotient. CONSTITUTION:The number of the light beam generating means is set to the measure 3 (101, 102, 103) except one out of 21, which is obtained by dividing the number of faces 25 of the rotatory polygon mirror 107 by the number of scanning lines. Because the number of the light beam generating means 101, 102 and 103 is set at three, three scanning lines are formed on a screen 110 at the same time. Therefore, rotatory speed of the rotatory polygon mirror 107 needs only 1/3 of scanning speed. When NTSC signal is given, rotating speed is determined by 15,750X60divided by Ndivided by 3rpm (N is the number of faces of the rotatory polygon mirror). Consequently, the device is miniaturized and its cost is lowered.
